The existing facility 8770 SW Scoffins) received Site development review approval for an office building in 1979 (SDR29-79). The current tenants have been in the building since 1990. The area to be expanded upon was addressed 8750 SW Scoffins and received Site Develoment Review approval in 1992 (SDR92-0003) to construct a residential treatment home group living facility) in conjunction with the Tualatin Valley Center. While this was approved, the improvements were never constructed and the approval expired. No other land use action was found in the City records for either of the addresses. Vicinity Information: The subject site is located on the south side of SW Scoffins Street. The property is bordered to the north by Scoffins and across the street by property developed with Commercial Retail uses. To the south and west, is property developed with a residential mobile home park. To the east is a sin le-family residence. All of the surrounding properties are zoned Central Business District CBD). Site Information and Proposal Description: The site consists of the existing 8,056 square foot facility and an existing single-family structure which is proposed to be demolished. The proposal is to construct a 12,036 square foot addition onto the existing facility to create a 20,092 square foot facility. The site will have access to shared parking on the parking lot across Scoffins Street which is part of the Rite Aid shopping center rear parking lot. The property is addressed as 8770 SW Scoffins; WCTM 2S102AA, Tax Lot 02800. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 4 OF 22 SECTION IV. COMMENTS FROM PROPERTY OWNERS WITHIN 500 FEET The Tigard Development Code requires that property owners within 500 feet of the subject site be notified of the proposal and be given the opportunity to provide written comments prior to a decision being made. Staff received written concerns which are summarized below. Copies of letters submitted are in the public record and are available for review at the City. One individual wrote with concerns about existing traffic congestion at the site due to school busses, taxis and vans waiting topick children up and dropping them off. It was stated that currently, Tualatin Valley Center parking spaces fill up which forces parking on the street, in the Rite-aid shopping center and blocking neighboring driveways. The concern is that the addition will result in more people coming to the site which will increase traffic congestion. An additional concern is visibility while entering onto Scoffins Street from the new driveway. Staff Response: Traffic will be addressed further in this decision under street and utility improvement standards. While the number of people coming to the site may increase, the design and layout of the parking will significantly increase the maneuverability of vehicles on-site. The applicant will be providing a one-way circular route around the building with loading towards the rear of the building. The applicant has also obtained permission to use a portion of the Rite-Aid shopping center for parking. Vision clearance has been addressed and Is discussed in detail further in this decision. Staff has reviewed the proposal with these concerns in mind and has imposed conditions necessary to address the,criteria, as well as, the concerns mentioned above. SECTION V.

Applicable Development Code Standards The Site development Review approval standards require that a development proposal be found to be consistent with the various standards of the Community Develo ment Code. The applicable criteria in this case are Chapters 18.360, 18.390, 18.5201 18.705, 18.745; 18.755, 18.765, 18.790, 18.795, and 18.810. The proposals consistency with these Code Chapters is reviewed in the following sections. The proposal contains no elements related to the following Development Code Chapters which are also listed under Section 18.360.090.A.1: 18.350 (Planned Developments), 18.715 (Density Computations), or 18.750 (Manufactured/Mobile Home Regulations) These Chapters are, therefore, found to be inapplicable as approval standards, and are not discussed in this decision. NOTICE OF TYPE 11 DECISION SDR2000-00017/rUALATIN VALLEY CENTER ADDITION PAGE 5 OF 22 Access, Egress and Circulation (18.705): Walkways: On-site pedestrian walkways shall comply with the following standards: Walkways shall extend from theground floor entrances or from the ground floor landing of stairs, ramps, or elevators of all commercial, institutional, and industrial uses, to the streets which provide the required access and egress. Walkways shall provide convenient connections between buildings in multi-building commercial, institutional, and industrial complexes. Unless impractical, walkways shall be constructed between new and existing developments and neighboring developments; The plans submitted by the applicant indicate that a walkway will be provided from street to the building entrance. Wherever required walkways cross vehicle access driveways or parking lots, such crossings shall be designed and located for pedestrian safety. Required walkways shall be physically separated from motor vehicle traffic and parking by either a minimum 6-inch vertical separation (curbed) or a minimum 3-foot horizontal separation, except that pedestrian crossings of traffic aisles are permitted for distances no greater than 36 feet if appropriate landscaping, pavement markings, or contrasting pavement materials are used. Walkways shall be a minimum of four feet in width, exclusive of vehicle overhangs and obstructions such as mailboxes, benches, bicycle racks, and sign posts, and shall be in compliance with ADA standards; The proposed walkway location crosses the parking lot access aisle. The section crossing the parking lot access aisle is 28 feet and will be marked with pavement striping, thus satisfying this criterion. Required walkways shall be paved with hard surfaced materials such as concrete, asphalt, stone, brick, etc. Walkways may be required to be lighted and/or signed as needed for safety purposes. Soft-surfaced public use pathways may be provided only if such pathways are provided in addition to required pathways. The entire parking lot will be paved with asphalt and the remaining portion of the walkway will be paved with concrete, therefore, this standard is met. Minimum Access Requirements for Commercial and Industrial Use: Section 18.705.030.1 provides the minimum access requirements for commercial and industrial uses: Table 18.705.3 indicates that the required access width for developments with less than 100 parking spaces is one 30 foot access point with 24 feet of pavement. Vehicular access shall be provided to commercial or industrial uses, and shall be located to within 50 feet of the primary ground floor entrances; additional requirements for truck traffic may be placed as conditions of site development review. The development will have less than 100 parking spaces and has 2 points of access into the parking lot. Both accesses have 24 feet of pavement. FINDING: Based on the analysis above, the access and egress standards have been satisfied. Landscaping and Screening (18.745)- Street Trees: Section 18.745.040 states that all development projects fronting on a public street or a private drive more than 100 feet in length shall be required to plant street trees in accordance with Section 18.745.040.0 Section 18.745.040.0 requires that street trees be spaced between 20 and 40 feet apart depending on the size classification of the tree at maturity (small, medium or large). Street trees are existing in front of the existing facility and the applicant has proposed to plant 2 Sunburst Locust trees spaced 30 feet on center. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 6 OF 22 Buffering and Screening: Section 18.745 Tables 1 & 2 state that a 10-20 foot buffer is required between a proposed office use and existing residential uses and a 6-10 foot buffer is required between parking lots and residential uses. The property to the east, west and south are developed with residential properties. The property to the west and south was developed residential as a mobile home park in 1979 when the existing facility was originally constructed. Because there is no change on this portion of the site and it was approved with the current landscapingbuffer, no additional buffer will be required in this area. A 10-20 foot buffer is required adjacent to the residential uses abutting the area of expansion. The buffer width adjacent to the area of expansion on the south and east is no less than 11 feet and as large as 21 feet. There is an existing dense hedge adjacent to the southern property line, however, because the buffer width is only 10 feet, the landscape standard has not been met. Staff will not require a wall to be constructed because doing so would damage the existing mature hedge. The applicant must, however, submit a revised landscape plan that shows at least 10, five-gallon or 20, one-gallon shrubs for every 1,000 square feet of required buffer and a row of trees spaced in accordance with the standards along both the south and east property lines. Screening: Special Provisions: Section 18.745.050.E requires the screening of parking and loading areas. Landscaped parking areas shall include special design features, which effectively screen the parking lot areas from view. Planting materials to be installed should achieve a relative balance between low lying and vertical shrubbery and trees. Trees shall be planted in landscaped islands in all parking areas, and shall be equally distributed on the basis of one (1) tree for each seven (7) parking spaces in order to provide a canopy effect. The minimum dimension on the landscape islands shall be three (3) feet wide and the landscaping shall be protected from vehicular damage by some form of wheel guard or curb. If the applicant complies with the condition listed above for buffering and screening, the parking lot screening standard will also be met along the property lines. The landscape plan does not show that landscaping will be provided adjacent to the street which will provide a balance of low lying and vertical shrubbery to effectively screen the parking lot (up to 3 feet) from view. The applicant's plans provide for new parking lot trees within the new parking lot areas with one tree for at least every 7 parking spaces. Screening of service facilities. Except for one-family and two-family dwellings, any refuse container or disposal area and service facilities such as gas meters and air conditioners which would otherwise be visible from a public street, customer or resident parking area, any public facility or any residential area shall be screened from view by placement of a solid wood fence or masonry wall between five and eight feet in height. All refuse materials shall be contained within the screened area; The applicant's plans do not show the location of service facilities, therefore, staff can not confirm that these areas will be screened in accordance with the standards. Screening of refuse containers. Except for one- and two-family dwellings, any refuse container or refuse collection area which would be visible from a public street, parking lot, residential or commercial area, or any public facility such as a school or park shall be screened or enclosed from view by placement of a solid wood fence, masonry wall or evergreen hedge. All refuse shall be contained within the screened area. The applicant's plans do not clearly show the refuse container will be screened. The existing refuse containers are not screened but are located in the back of the site. The applicant must submit a plan that clearly shows the trash enclosure will be screened. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 7 OF 22 FINDING: Based on the analysis above, the landscaping and screening standards have not been fully met. If the applicant complies with the conditions listed below, the standards will be met. CONDITIONS: Submit a revised landscape plan that shows at least 10, five-gallon or 20, one-gallon shrubs for every 1,000 square feet of required buffer and a row of trees spaced in accordance with the standards along both the south and east property Imes. The landscape plan must also show a 6-foot fence will be installed along the east property line, adjacent to the residential use. Submit a revised plan that shows that service facilities (gas meters, air conditioners, etc.)will be screened from view. Submit a revised plan that clearly shows the trash enclosure will be screened by a 6-foot wood fence. Mixed Solid Waste and Recyclables Storage (18.755): Chapter 18.755 requires that new construction incorporates functional and adequate space for on-site storage and efficient collection of mixed solid waste and source separated Recyclables prior to pick-up and removal by haulers. The applicant must choose one (1) of the following four (4) methods to demonstrate compliance: Minimum Standard, Waste Assessment, Comprehensive Recycling Plan, or Franchised Hauler Review and Sign-Off. The applicant will have to submit evidence or a plan that indicates compliance with this section. The applicant's narrative does not address mixed solid waste and recyclable storage. The site plan shows the location of the proposed trash enclosure, but there has been no evidence that the size and location of the proposed trash enclosure meets any of the options available. The applicant must provide evidence that the size and location meets one of the 4 compliance methods listed above. Location standards. To encourage its use, the storage area for source-separated recyclable shall be co- located with the storage area for residual mixed solid waste; Indoor and outdoor storage areas shall comply with Uniform Building and Fire Code requirements; Storage area space requirements can be satisfied with a single location or multiple locations, and can combine both interior and exterior locations; Exterior storage areas can be located within interior side yard or rear yard areas. Exterior storage areas shall not be located within a required front yard setback or in a yard adjacent to a public or private street; Exterior storage areas shall be located in central and visible locations on a site to enhance security for users; Exterior storage areas can be located in a parking area, if the proposed use provides at least the minimum number of parking spaces required for the use after deducting the area used for storage. Storage areas shall be appropriately screened according to the provisions in 18.755.050 C, design standards; The storage area shall be accessible for collection vehicles and located so that the storage area will not obstruct pedestrian or vehicle traffic movement on the site or on public streets adjacent to the site. The location proposed is in the rear of the building and is not ad)acent to a public or private street. While the proposed location is not within any required parking areas, it appears that it will only be accessible through a parking space. The location must be oriented so that it can be serviced without the need for service trucks to utilize parking spaces. There is no detail indicating that the refuse containers will be screened by a 6-foot wood fence. The waste hauler has not signed off on the location, therefore, staff can not confirm that the location is accessible to their trucks and meets their locational needs. The applicant must revise the location so it is oriented in such a way that service trucks will not have to utilize parking spaces to service the trash. The applicant has been conditioned previously to screen the trash enclosure. The applicant must submit written sign-off from the waste hauler that the location is accessible to their trucks. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 8 OF 22 Design standards. The dimensions of the storage area shall accommodate containers consistent with current methods of local collection; Storage containers shall meet Uniform Fire Code standards and be made and covered with waterproof materials or situated in a covered area; Exterior storage areas shall be enclosed by a sight-obscuring fence wall, or hedge at least six feet in height. Gate openings which allow access to users and haulers shall be provided. Gate openings for haulers shall be a minimum of 10 feet wide and shall be capable of being secured in a closed and open position; Storage area(s) and containers shall be clearly labeled to indicate the type of materials accepted. The applicant has not submitted detail of the trash enclosure or refuse container. The applicant must submit details addressing the design standards in order for Staff to determine that this standard has been met. FINDING: Because the applicant has not provided evidence that the mixed solid waste and recyclables storage location is accessible to waste hauler vehicles and staff, this standard has not been met. If the applicant complies with the condition listed below, the standards will be met. CONDITIONS: Submit information indicating how theproposed trash enclosure meets one of the 4 compliance methods listed In Chapter 18.755. Revise the location so it is oriented in such a way that service trucks will not have to utilize parking spaces to service the trash. Submit confirmation from the waste hauler that the location of the proposed receptacle is accessible to their vehicles and staff. The applicant must submit details addressing the trash enclosure design standards in order for Staff to determine that the standards will be met. Off-Street Parking and Loading (18.765): Preferential long-term carpoo /vanpool parking: Parking lots providing in excess of 20 long-term parking spaces shall provide preferential long-term carpool and vanpool parking for employees, students and other regular visitors to the site. At least 5% of total long-term parking spaces shall be reserved for carpool/vanpool use. Preferential parking for carpools/vanpools shall be closer to the main entrances of the building than any other employee or student parking except parking spaces designated for use by the disabled. Preferential carpool/vanpool spaces shall be full-sized per requirements in Section 18.765.040N and shall be clearly designated for use only by carpools and vanpools between 7:00 AM and 5:30 PM Monday through Friday. The plans provide for more than 20 parking spaces, therefore, carpool/vanpool parking is required. The narrative does not address carpool parking requirements The applicant must provide at least 5% carpool spaces based on the number provided on-site. Because the number of spaces provided on-site will change as a result of conditions within this decision, staff can not state the exact number of carpool spaces required. The applicant will be conditioned to designate (with pavement marking and/or signs at least 5% of the spaces as carpool. Disabled-accessible parking: All parking areas shall be provided with the required number of parking spaces for disabled persons as specified by the State of Oregon Uniform Building Code and federal standards. Such parking spaces shall be sized, signed and marked as required by these regulations. NOTICE OF TYPE 11 DECISION SDR2000-00017lTUALATIN VALLEY CENTER ADDITION PAGE 9 OF 22 The applicant has shown 40 parking spaces on-site (with additional parking to be provided via a shared parking agreement), therefore, 2 ADA handicap spaces are required, one (1) of which is van accessible (9 feet wide with and 8-foot aisle). The applicant's site plan (sheet SD3) shows 2 spaces will be marked as ADA accessible. Bot spaces are van accessible. Access Drives: With regard to access to public streets from off-street parking: access drives from the street to off-street parking or loading areas shall be designed and constructed to facilitate the flow of traffic and provide maximum safety for pedestrian and vehicular traffic on the site- the number and size of access drives shall be in accordance with the requirements of 6hapter, 18.705 Access Egress and Circulation; access drives shall be clearly and permanently marked and defined through use of rails, fences, walls or other barriers or markers on frontage not occupied by service drives; access drives shall have a minimum vision clearance in accordance with Chapter 18.795, Visual Clearance; access drives shall be improved with an asphalt or concrete surface; and excludin single-family and duplex residences, except as provided by Subsection 18.810.030 groups of two or more parking spaces shall be served by a service drive so that no acking movements or other maneuvering within a street or other public right-of-way will be required. The driveway andparking will be asphalted in accordance with the requirements. The number and size of the access drives is regulated by the standards specified in Section 18.705.030 and has been. discussed previously in this decision. Vision clearance will be addressed further in this decision. Loading/Unloading Driveways: A driveway designed for continuous forward flow of passenger vehicles for the purpose of loading and unloading passengers shall be located on the site of any school or other meeting place which is designed to accommodate more than 25 people at one time. Staff received comments that there is currently a problem with vehicles coming to drop students off and pick them up. While this will be alleviated slightly by the new driveway layout, the applicant still must designate a location, outside of the required aisle width, to provide for dropping off and picking up of students. Staff has determined that this is feasible if the access aisle is designated one-way as will be discussed further in this decision. A condition is necessary in order for this standard to be fully met. Pedestrian Access: Pedestrian access through parking lots shall be provided in accordance with Section 18.705.030.F. Where a parking area or other vehicle area has a drop-off grade separation, the property owner shall install a wall, railing, or other barrier which will prevent a slow-moving vehicle or driverless vehicle from escaping such area and which will prevent pedestrians from walking over drop-off edges. Pedestrian access has been discussed previously in this decision. Parking Lot Striping: Except for single-family and duplex residences, any area intended to be used to meet the off-street parking requirements as contained in this Chapter shall have all parking spaces clearly marked; and all interior drives and access aisles shall be clearly marked and signed to show direction of flow and maintain vehicular and pedestrian safety. The plans submitted show the parking spaces on-site will be clearly marked with striping The site plan shows the southern portion of the drive to the rear of the building will be one-way and marked accordingly. As will be discussed in more detail further in this decision, the northern access aisle serving the rear of the site must be marked one-way as well due to the aisle width of only 18 feet. In addition, signage is necessary at the entrance to the one-way drive indicating "exit only" and "entrance only". A site visit revealed the existing striping on the lot across the street is basically non-existent. In order to be permitted to use this parking as part of the shared parking, the lot must be striped with the required parking dimensions. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 10 OF 22 Wheel Stops: Parking spaces along the boundaries of a parking lot or adjacent to interior landscaped areas or sidewalks shall be provided with a wheel stop at least four inches high located three feet back from the front of the parking stall. The front three feet of the parking stall may be concrete, asphalt or low lying landscape material that does not exceed the height of the wheel stop. This area cannot be calculated to meet landscaping or sidewalk requirements. While the applicant's vicinity map dated October 6, 2000 shows wheel stops, the site plan set dated July , 2000 does not show wheel stops will be installed. Wheel stops are required where the parking abuts walkways and landscaping areas. If curbs are installed adjacent to the landscape areas, the vehicle may overhang into the landscape area provided the landscaping is low growing and the 3 foot area of vehicle overhang is excluded from the landscape percentage calculations. The applicant must submit revised plans that show wheel stops will be provided where the parking abuts landscaping and walkways or that shows the 3 foot landscape strip adjacent to parking will be planted with low lying shrubbery and is excluded from the landscape percentage. Space and Aisle Dimensions: Section 18.765.040.N states that: "except as modified for angled parking in Figures 18.765.1 and 18.765.2 the minimum dimensions forparking spaces are: 8.5 feet x 18.5 feet for a standard space and 7.5 feet x 16.5 feet for a compact space; aisles accommodating two direction traffic, or allowing access from both ends, shall be 24 feet in width. The site plan dated July 26, 2000 shows 39 parking spaces provided on-site, whereas, the vicinity map dated October 6, 2000 shows 40. Both of these plans have parking spaces that do not provide the adequate space and aisle dimensions. Staff s comments are based on the site plan as opposed to the vicinity map. All of the 90 degree parking spaces are dimensioned adequately and meet the aisle dimension standards of 24 feet. The parallel spaces along the northern property line, however, are of concern. The Code does not have dimensional criteria for parallelparking spaces. The Engineering Department uses the Manual for Uniform Traffic Control Devices (MUTCD) for parallel parking on streets. If using the MUTCD as a guide, the required minimum length for parallel parking spaces is 20 feet by 8 feet. The applicant has shown the spaces will be 20 feet in length and 8'6" in width. The parallel parking space closest to the street creates an access aisle width of only 18 feet which is not adequate for 2-way traffic. Because the driveway is circular, the northern access drive could be designed as one-way, thus alleviating the access aisle width issue. The parallel parking space furthest from the street is not adeqquate because it provides no maneuvering room to pull into and out of theparking space. The roper way to parallel park is to pull up and then back into the space, however, because of the layout of the parking lot, it is not possible to do that for this proposed space. This space does not exist on the current site and must be eliminated from the site plans. The applicant attempted to show an additional parking space closer to the street on the vicinity plan, however, this would result in an access aisle that is only 11 feet wide. The applicant must revise the plan to provide for parking spaces that meet the access aisle and dimension requirements and also provides for necessarymaneuvering for vehicles to get into the parkingg s aces. The Code allows off-street arking to be located within 200 feet of the building tFiat theare required to serve. The applicant has indicated that they have a joint parking agreemen with the lot across the street, evidence of which will be conditioned within this decision. Because this parking lot is within 200 feet of the building, this parking may be used and the parking on-site may be reduced in order to meet the other conditions of approval. Bicycle Parking Location and Access: Section 18.765.050 states bicycle parking areas shall be provided at locations within 50 feet of primary entrances yo structures; bicycleparking areas shall not be located within parking aisles, landscape areas or pedestrian ways; outdoor bicycle parking shall be visible from on-site buildings and/or the street. When the bicycle parking area is not visible from the street, directional signs shall be used to located the parking area; and bicycle parking may be located inside a building on a floor which has an outdoor entrance open for use and floor location which does not require the bicyclist to use stairs to gain access to the space. . Exceptions may be made to the latter requirement for parking on upper stories within a multi-story residential building. NOTICE OF TYPE 11 DECISION SDR2000-00017frUALATIN VALLEY CENTER ADDITION PAGE 11 OF 22 The plan shows a 10 space bicycle rack will be provided near the main entrance of the building within 50 feet of the building entrance. Bicycle Parking gg Design Requirements: Section 18.765.050.C. The following design requirements apply to the installation of bicycle racks: The racks required for required bicycle parking spaces shall ensure that bicycles may be securely locked to them without undue inconvenience. Provision of bicycle lockers for long-term (employee) parking is encouraged but not required; bicycle racks must be securely anchored to the ground, wall or other structure; bicycle parking spaces shall be at least 21/2 feet by six feet long, and, when covered, with a vertical clearance of seven feet. An access aisle of at least five feet wide shall be provided and maintained beside or between each row of bicycle parking; each required bicycle parking space must be accessible without moving another bicycle; required bicycle parking spaces may not be rented or leased except where required motor vehicle parking is rented or leased. At-cost or deposit fees for bicycle parking are exempt from this requirement; and areas set aside for required bicycle parking must be clearly reserved for bicycle parking only. Outdoor bicycle parking facilities shall be surfaced with a hard surfaced material, i.e., pavers, asphalt, concrete or similar material. This surface must be designed to remain well drained. The applicant has not provided a detail of the bike rack to be used, therefore, staff is unable to confirm that this standard is met. Minimum Bicycle Parking Requirements: The total number of required bicycle parking spaces for each use is specified in Table 18.765.2 in Section 18.765.070.H. In no case shall there be less than two bicycle parking spaces. Table 18.765.2 states that for Medical Office Uses, .4 bicycle parking spaces are required for every 1,000 square feet of gross floor area, therefore, 8 bicycle parking spaces must be provided. The applicant's plan indicates 10 bicycle spaces will be provided near the main building entrance. Provided the applicant complies with the condition previously discussed for bicycle parking design this standard will be met. Minimum Off-Street Parking: Section 18.765.070.H states that the minimum and maximum parking shall be as required in Table 18.765.2. Table 18.765.2 states that the minimum parking for a Medical Office Use is 3.9 spaces per 1000 square feet and the maximum is 98 parking spaces per 1000 square feet (Parking Zone A). The applicant is, therefore, required to provide between 78 and 98 parking spaces based on the total building square footage. The Site Plan (sheet SD3) shows 39 parking spaces, however, the Vicinity map (Sheet SD1.1) shows 40 spaces on-site and 15 additional spaces across the street. The Code permits shared parking arrangements when the shared parking is within 200 feet of the use, and the parking is in excess of the required parking for the site providing the shared parking. The shared parking area is behind the existing Rite-Aid shopping center. The Rite-Aid shopping center is required to have 265 parking spaces. There are currently 288 parking spaces in front of the shopping center and 70 spaces in the rear. Because the shopping center has more parking than is required for the use, the Tualatin Valley Center may utilize some of the parking in the rear of the shopping center. The shopping center parking lot is within 200 feet of the site. While the Vicinity Map shows 40 parking spaces, the dimensions will not meet the criteria (as discussed in detail previously in this decision). The applicant has been conditioned to meet the dimensional requirements for the 40 required parking spaces on-site. In addition, the applicant utilized general office parking requirements instead of medical office parking requirements, therefore, the applicant must have access to 38 parking spaces on the Rite-Aid shopping center site instead of the 15 previously proposed. While the applicant submitted a written agreement from a representative of the Rite-Aid shopping center indicating that they may use their excess parking, this agreement must be formalized and recorded so that it is binding on the property to insure that the shopping center can not remove the shared parking agreement and thus bring the Tualatin Valley Center site into non-compliance. NOTICE OF TYPE 11 DECISION SDR2000-00017(TUALATIN VALLEY CENTER ADDITION PAGE 12 OF 22 Off-Street Loading Spaces: Commercial, industrial and institutional buildings or structures to be built or altered which receive and distribute material or merchandise by truck shall provide and maintain off-street loading and maneuvering space as follows: A minimum of one loading space is required for buildings with 10,000 gross square feet or more; A minimum of two loading spaces for buildings with 40,000 gross square feet or more. The building will be over 10,000 square feet, thus requiring a loading space. The siteplan shows a loading space, however, it is located in the middle of the access aisle and, therefore, can not be approved. The applicant must submit a revised plan that provides for a loading space which will not obstruct traffic or take up required parking. FINDING: Based on the analysis above, the off-streetparking and loading standards have not been fully met, however, if the applicant complies with the conditions listed below, the standards will be fully met. CONDITIONS: Submit a revised pplan that clearly shows at least 5% of the parking spaces on-site will be designated as carpool parking spaces. Submit a revised plan that shows the location of a drop-off and pick-up loading zone that is outside of the required aisle width. Submit a revised plan that shows the northern access aisle to the rear of the lot will be marked as one-way. Staff recommends that this be designated one-way going out and the southern access drive be designated one-way going in. The plans must indicate signage, as well as, pavement markings will be used. Prior to final inspection and occupancy, the parking used as part of the shared parking in the Rite-Aid parking lot must be re-striped so that the spaces are clearly visible. Submit a revised plan that shows wheel stops will be installed where the parking abuts walkways and landscaping. Alternatively, the plan may show a curb and low growing landscaping where the parking abuts landscaping as long as the applicant provides evidence that the landscape percentages are met after excluding the 3-foot overhang area from the landscape calculations. Submit a revisedplan that provides for parking spaces that meets the access aisle and dimensions requirements and also provides for necessary maneuvering for vehicles to get into the parking spaces. Submit details of the bicycle rack to be used. Submit a copy of a formal and binding (recorded) agreement with the Rite-Aid shopping center indicating that Tualatin Valley Center may share at least 38 (or more as needed to total 78 over both parking lots) parking spaces. Submit a revised plans that provides for a loading space that does not block vehicle access within the parking lot or takes up required parking. Si ns (18.780): Chapter 18.780.130.D lists the type of allowable signs and sign area permitted in the CBD Zoning District. NOTICE OF TYPE 11 DECISION SDR2000-00017rrUALATIN VALLEY CENTER ADDITION PAGE 13 OF 22 The applicant has one existing sign. The narrative indicates that the applicant would like to install an additional sign at the new driveway entrance to allow for better visibility in order to avoid potential problems with cars braking suddenly to turn into the site. The sign code does not allow for more than 1 sign in this zone unless it has multiple street frontages. The existing sign is non-conforming because it is within the vision clearance area. Staff is requiring a condition to alter the location of the existing sign to increase visibility from both directions. The new sign location will be reviewed through a separate permit process administered by the Planning and Engineering Permit Technicians. FINDING: Because a sign permit has not been obtained for the re-location of the sign so that it is outside of vision clearance areas, this standard has not been met. If the applicant obtains a sign permit, this standard will be satisfied. CONDITION: Prior to final building inspection, apply for and receive a sign permit to alter the location of the existing sign so that it is not within a vision clearance area. Tree Removal (18.790 S_e_c_fi`on18.790.030 requires that a tree plan for the planting, removal and protection of trees prepared b a certified arborist shall be provided with a site development review application. The by plan shall include identification of all existing trees, identification of a program to save existing trees or mitigate tree removal over 12 inches in caliper, which trees are to be removed, protection program defining standards and methods that will be used by the applicant to protect trees during and after construction. The applicant has submitted a landscape plan that shows trees to be removed. They have also submitted a tree preservation and mitigation plan, however, the two plans submitted do not match. The tree preservation and mitigation plan, preppared by a certified arborist, refers to a map that is not attached. It indicates that there are 15 trees on the site over 12 inches that must be removed. The landscape plan (sheet SD4) shows only 11 trees that are to be removed and the numbers do not correspond to the numbers on the plan prepared by the arborist. The applicant must submit a plan that clearly shows the size and location of all trees in the site over 12 inches and those that are to be removed. Mitigation will be required based on the number of trees and inches removed. FINDING: Based on the analyysis above, staff can not confirm that the tree removal standards are met. If the applicant complies with the conditions listed below, the standards will be met. CONDITIONS: Submit a plan and arborist report that clearly shows the number, location, and size of all existing trees on the site and the number of 12 inch trees that will be removed. Based on the percentage of trees to be removed versus retained, submit a mitigation plan for the caliper inches removed indicating whether planting will be done on-site, off-site, or by paying the fee in-lieu. Prior to any site work, install tree protection measures for trees that are to be retained. Prior to final inspection, tree mitigation must be completed. Visual Clearance Areas (18.795 Chapter 18.795 requires that a clear vision area shall be maintained on the corners of all property adjacent to intersecting right-of-ways or the intersection of a public street and a private driveway. A clear vision area shall contain no vehicle, hedge, lanting, fence, wall structure, or temporary or permanent obstruction exceeding three (3rfeet in height. The code provides that obstructions that may be located in this area shall be visually clear between three (3) and eight (8) feet in height (8) (trees may be placed within this area provided that all branches below eight (8) feet are removed). A visual clearance area is the triangular area formed by measuring a 30-foot distance along the street right- of-way and the driveway, and then connecting these two (2), 30-foot distance points with a straight line. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 14 OF 22 The site plan does not identify the vision clearance areas. The narrative indicates that the standards are met, however, when staff scaled the vision clearance areas off on the plans, parking, landscaping and the existing and proposed signs are located within these areas. The plans must be revised to show no parking and only low growing vegetation will be located within the vision clearance area adjacent to the easternmost driveway and to show the existing sign will be re-located as conditioned previously. FINDING: Based on the analysis above, the vision clearance standards have been not been met. If the applicant complies with the condition below, the standards will be met. CONDITION: Submit a revised landscape plan that shows no parking or vegetation will be located in the vision clearance area at the easternmost driveway that exceed 3 feet in height. B. Specific Site Development Review Approval Standards Section 18.360.090(A)(2) through 18.360.090(A)(15) provides additional Site Development Review approval standards not necessarily covered by the provisions of the previously listed sections. These additional standards are addressed immediately below with the following exceptions: The proposal contains no elements related to the provisions of the following and are, therefore, found to be inapplicable as approval standards: 18.360.090.3 (Exterior Elevations);); 18.360.090.5 (Privacy and Noise: Multi-family or Group Living Uses); 18.360.090.6 (Private Outdoor Areas: Multi-family Use); 18.360.090.7 (Shared Outdoor Recreation Areas: Multi-family Use); and 18.360.090.9 (Demarcation of Spaces). The following sections were discussed previously in this decision and, therefore, will not be addressed in this section: 18.360.090.4 Buffering Screening and Compatibility Between Adjoining Uses; 18.360.090.13 Parking); 18. 60.090.14 (Landscaping); 18.360.090.15 (Drainage); and 18.360.090.14 Provision for the Disabled). Relationship to the Natural and Physical Environment: Buildings shall be: located to preserve existing trees, topography and natural drainage where possible based upon existing site conditions; located in areas not subject to ground slumping or sliding; located to provide adequate distance between adjoining buildings for adequate light, air circulation, and fire-fighting; and oriented with consideration for sun and wind. Trees shall be preserved to the extent possible. Replacement of trees is subject to the requirements of Chapter 18.790, Tree Removal. Because the proposal is an addition onto an existing building, the location can not be altered. The proposal wilt retain as many trees on-site as possible. The area is not subject to slumping or sliding and there are no known natural drainage areas on the site. The Fire Department has reviewed the proposal and provided comments which have been incorporated into this decision. They did not raise any concerns with the building location, orientation or design. FINDING: Based on the analysis above, this standard has been satisfied. Crime Prevention and Safety: Windows shall be located so that areas vulnerable to crime can be surveyed by the occupants; Interior laundry and service areas shall be located in a way that they can be observed by others; Mail boxes shall be located in lighted areas having vehicular or pedestrian traffic; NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 15 OF 22 The exterior lighting levels shall be selected and the angles shall be oriented towards areas vulnerable to crime; and Light fixtures shall be provided in areas having heavy pedestrian or vehicular traffic and in potentially dangerous areas such as parking lots, stairs, ramps and abrupt grade changes. Fixtures shall be placed at a height so that light patterns overlap at a height of seven feet, which is sufficient to illuminate a person. Windows are oriented towards the parking lots. The City of Tigard Police Department has reviewed this project and has requested that a lighting plan be provided for their review. Because the Police Department has indicated that a lighting plan is needed, the Crime Prevention and Safety standards have not been fully met. If the applicant submits a lighting plan for review and approval to the Police Department, the standards will be met. Please note that the lighting must be directed away from the residential properties. FINDING: Because the Police Department has indicated that they must see a lighting plan, this standard has not been met. If the applicant complies with the condition specified below, the standard will be met. CONDITION: Submit a lighting plan to the Police Department for review and approval. The lighting plan must also show that lights will be directed away from the residential properties and the public right-of-way. Public Transit: Provisions within the plan shall be included for providing for transit if the development proposal is adjacent to existing or proposed transit route; the requirements for transit facilities shall be based on: the location of other transit facilities in the area; and the size and type of the proposal. The following facilities may be required after City and Tri-Met review: bus stop shelters; turnouts for buses; and connecting paths to the shelters. The site has frontage on SW Scoffins which is within a '/< mile of a Tri-met transit route. Staff sent a request for comments to Tri-met, however, they did not respond with a request for the applicant to provide additional transit facilities along the frontage. FINDING: Based on the analysis above, this standard is satisfied. 100-year floodplain Where landfill and/or development is allowed within and adjacent to the 100-year floodplain, the City shall require consideration of the dedication of sufficient open land area for greenway adjoining and within the floodplain. This area shall include portions at a suitable elevation for the construction of a pedestrian/bicycle pathway within the floodplain in accordance with the adopted pedestrian/ bicycle plan. The property is not within or adjacent to the 100-year floodplain, therefore, this standard does not apply. FINDING: Based on the information above, this standard does not apply. Provisions of the Underlying Zone: All of the provisions and reguy lations of the underlying zone shall app/ unless modified by other sections or this title, e.g., Planned Developments, Chapter 18.350; or a variance or adjustment granted under Chapter 18.370. Use Classification: The applicant is proposing to construct an addition onto the existing day treatment counseling facility The zone is CBD. The proposed use would be considered a counseling office which is allowed in this zone. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 16 OF 22 Dimensional Requirements: The following table compares the dimensional requirements with the proposed requirements.

Street And Utility Improvement Standards (18.810) Street And Utility Improvements Standards (Section 18.810): Chapter 18.810 provides construction standards for the implementation of public and private facilities and utilities such as streets, sewers, and drainage. The applicable standards are addressed below: Streets: Improvements: Section 18.810.030.A.1 states that streets within a development and streets adjacent shall be improved in accordance with the TDC standards. Section 18.810.030.A.2 states that any new street or additional street width planned as a portion of an existing street shall be dedicated and improved in accordance with the TDC. Minimum Rights-of-Way and Street Widths: Section 18.810.030(E) requires a local commercial/industrial street to have a 50-foot right-of-way width and a 34-foot paved section. Other improvements required may include on-street parking, sidewalks and bikeways, underground utilities, street lighting, storm drainage, and street trees. This site lies adjacent to SW Scoffins Street, which is classified as a local commercial/industrial street on the City of Tigard Transportation Plan Map. At present, there is approximately 50 feet of ROW, according to the most recent tax assessor's map. No additional dedications are necessary. SW Scoffins Street is currently fully improved adjacent to this site. No additional improvements are necessary. The applicant's plan shows that a new 25-foot wide driveway is proposed near the east boundary of the site to serve the parking area adjacent to the new addition. The driveway location meets City requirements for driveway spacing and setbacks from a property line. Sidewalks: Section 18.810.070.A requires that sidewalks be constructed to meet City design standards and be located on both sides of arterial, collector and local residential streets. SW Scoffins Street is already improved with sidewalk adjacent to this site. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 17 OF 22 Sanitary Sewers: Sewers Required: Section 18.810.090.A requires that sanitary sewer be installed to serve each new development and to connect developments to existing mains in accordance with the provisions set forth in Design and Construction Standards for Sanitary and Surface Water Management (as adopted by the Unified Sewerage Agency in 1996 and including any future revisions or amendments) and the adopted policies of the comprehensive plan. Over-sizing: Section 18.810.090.0 states that proposed sewer systems shall include consideration of additional development within the area as projected by the Comprehensive Plan. There is an existing 8-inch public sanitary sewer line located in SW Scoffins Street that can serve the new building addition. The applicant must obtain a Street Opening Permit to perform the sewer connection work in the ROW of SW Scoffins Street. Storm Drainage: General Provisions: Section 18.810.100.A states requires developers to make adequate provisions for storm water and flood water runoff. Accommodation of Upstream Drainage: Section 18.810.100.0 states that a culvert or other drainage facility shall be large enough to accommodate potential runoff from its entire upstream drainage area, whether inside or outside the development. The City Engineer shall approve the necessary size of the facility, based on the provisions of Design and Construction Standards for Sanitary and Surface Water Management (as adopted by the Unified Sewerage Agency in 2000 and including any future revisions or amendments). The applicant's plan provides new onsite catch basins and storm drainage piping to collect all onsite runoff and will allow collection of any offsite runoff that currently flows onto the site. Effect on Downstream Drainage: Section 18.810.100.1) states that where it is anticipated by the City Engineer that the additional runoff resulting from the development will overload an existing drainage facility, the Director and Engineer shall withhold approval of the development until provisions have been made for improvement of the potential condition or until provisions have been made for storage of additional runoff caused by the development in accordance with the Design and Construction Standards for Sanitary and Surface Water Management (as adopted by the Unified Sewerage agency in 2000 and including any future revisions or amendments). In 1997, the Unified Sewerage Agency (USA) completed a basin study of Fanno Creek and adopted the Fanno Creek Watershed Management Plan. Section V of that plan includes a recommendation that local governments institute a stormwater detention/effective impervious area reduction program resulting in no net increase in storm peak flows up to the 25-year event. The City will require that all new developments resulting in an increase of impervious surfaces provide onsite detention facilities, unless the development is located adjacent to Fanno Creek. For those developments adjacent to Fanno Creek, the storm water runoff will be permitted to discharge without detention. The applicant's plan proposes an onsite detention pipe to accommodate the 25-year detention requirement. The pipe concept is acceptable, but the final design should include convenient manhole access Into the detention pipe for cleaning purposes. The property owner will be required to maintain this pipe. The applicant's plan also shows that their onsite stormwater runoff will be conveyed into the ROW of SW Scoffins Street. The plan shows an offsite extension of a public storm drainage line from the east. This new public storm line extension will be terminated at the site because there is a crest in the roadway adjacent to where the new addition will be constructed. In summary, the applicant's storm drainage plan is acceptable. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 18 OF 22 Bikeways and Pedestrian Pathways: Bikeway Extension: Section 18.810.110.A states that developments adjoining proposed bikeways identified on the City's adopted pedestrian/bikeway plan shall include provisions for the future extension of such bikeways through the dedication of easements or right-of-way. The proposed development does not abut a bikeway, therefore this standard does not apply. Utilities: Section 18.810.120 states that all utility lines, but not limited to those required for electric, communication, lighting and cable television services and related facilities shall be placed underground, except for surface mounted transformers, surface mounted connection boxes and meter cabinets which may be placed above ground, temporary utility service facilities during construction, high capacity electric lines operating at 50,000 volts or above, and: The developer shall make all necessary arrangements with the serving utility to provide the underground services; The City reserves the right to approve location of all surface mounted facilities; All underground utilities, including sanitary sewers and storm drains installed in streets by the developer, shall be constructed prior to the surfacing of the streets; and Stubs for service connections shall be long enough to avoid disturbing the street improvements when service connections are made. Exception to Under-Grounding Requirement: Section 18.810.120.0 states that a developer shall pay a fee in-lieu of under-grounding costs when the development is proposed to take place on a street where existing utilities which are not underground will serve the development and the approval authority determines that the cost and technical difficulty of under-grounding the utilities outweighs the benefit of under-grounding in conjunction with the development. The determination shall be on a case-by-case basis. The most common, but not the only, such situation is a short frontage development for which under-grounding would result in the placement of additional poles, rather than the removal of above-ground utilities facilities. An applicant for a development which is served by utilities which are not underground and which are located across a public right-of-way from the applicant's property shall pay a fee in-lieu of under-grounding. There are existing overhead utility lines along SW Scoffins Street. If the fee in-lieu is proposed, it is equal to $27.50 per lineal foot of street frontage that contains the overhead nes. The frontage along this site is 190 lineal feet; therefore the fee would be $5,225.00. ADDITIONAL CITY AND/OR AGENCY CONCERNS WITH STREET AND UTILITY IMPROVEMENT STANDARDS: Public Water System: There is an existing City water main in SW Scoffins Street that can serve the new addition. The plans show that there is an existing water meter that will be used to serve the new addition. Storm Water Quality The City has agreed to enforce Surface Water Management (SWM) regulations established by the Unified Sewerage Agency (USA) Design and Construction Standards (adopted by Resolution and Order No. 00- ) which require the construction of on-site water quality facilities. The facilities shall be designed to remove 65 percent of the phosphorus contained in 100 percent of the storm water runoff generated from newly created impervious surfaces. In addition, a maintenance plan shall be submitted indicating the frequency and method to be used in keeping the facility maintained through tg a year. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 19 OF 22 Prior to issuance of the site permit, the applicant shall submit plans and calculations for a water quality facility that will meet the intent of the USA Design Standards. In addition, the applicant shall submit a maintenance plan for the facility that must be reviewed and approved by the City prior to construction. The applicant's plans indicate they will treat the onsite surface water runoff with two Stormwater Management catch basin filter units. These units have been approved for use on privately maintained systems, provided the owner enters into a maintenance contract with Stormwater Management. To ensure compliance with Unified Sewerage Agency, design and construction standards, the applicant shall employ the design engineer responsible for the design and specifications of the private water quality facility to perform construction and visual observation of the water quality facility for compliance with the design and specifications. These inspections shall be made at significant stages throughout the project and at completion of the construction. Prior to final building inspection, the design engineer shall provide the City of Tigard (Inspection Supervisor) with written confirmation that 1he water quality facility is in compliance with the design and specifications. Gradina and Erosion Control: USA Design and Construction Standards also regulate erosion control to reduce the amount of sediment and other pollutants reaching the public storm and surface water system resulting from development, construction, grading, excavating, clearing, and any other activity which accelerates erosion. Per USA regulations, the applicant is required to submit an erosion control plan for City review and approval prior to issuance of City permits. Grading and erosion control plans will be required to be submitted to the Building Division prior to construction. C. Impact Study (18.390) Section 18.360.090 states, "The Director shall make a finding with respect to each of the following criteria when approving, approving with conditions or denying an application:" Section 18.390.040 states that the applicant shall provide an impact study to quantify the effect of development on public facilities and services. For each public facility system and type of impact, the study shall propose improvements necessary to meet City standard, and to minimize the impact of the development on the public at large, public facilities systems, and affected private property users. In situations where the Community Development Code requires the dedication of real property interests, the applicant shall either specifically concur with a requirement for public right-of-way dedication, or provide evidence that supports that the real property dedication is not roughly proportional to the projected impacts of the development. Section 18.390.040 states that when a condition of approval requires the transfer to the public of an interest in real property, the approval authority shall adopt findings which support the conclusion that the interest in real property to be transferred is roughly proportional to the impact the proposed development will have on the public. The applicant has provided an impact study addressingg the project's impacts on public systems. The Washington County Traffic Impact Fee (TIF) is a mitigation measure that is required at the time of development. Based on a transportation impact study prepared by Mr. David Larson for the A-Boy Expansion/Dolan II/Resolution 95-61, TIF's are expected to recapture 32 percent of the traffic impact of new development on the Collector and Arterial Street system. The applicant will be required to pay TIF's of approximately $55,836 based on the use proposed. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 20 OF 22 Based on the estimate that total TIF fees cover 32 percent of the impact on major street improvements citywide, a fee that would cover 100 percent of this projects traffic impact is $174,487 ($55,836 divided by .32). The difference between the TIF paid, and the full impact, is considered the unmitigated Impact on the street system. The unmitigated impact of this project on the transportation system Is $118,651 . There is no dedication or improvement requirement for this project. SECTION VII. OTHER STAFF COMMENTS The City of Tigard Building Division has reviewed this application and offered the following comments: 1. Will require 3 hydrants; 2.) Existing building will require a total seismic and ADA upgrade; 3. An elevator will be required; 4.) Existing will require energy code upgrade; 5.) Depending on use, this may be an I Division 1.1 occupancy. Note: Applicant must contact Building Department directly regarding these comments.

TUALATIN VALLEY CENTER ADDITION si /..1Z .0 A ny or b.b P' t \ REQUEST FOR COMMENTS MEMORANDUM CITY OF TIGARD, OREGON DATE: November 20, 2000 TO: Julia Hajduk, Associate Planner FROM: Brian Rager, Development Review Engineer RE: SDR 2000-00017, Tualatin Valley Centers Addition Street And Utility Improvements Standards (Section 18.810 Chapter 18.810 provides construction standards for the implementation of public and private facilities and utilities such as streets, sewers, and drainage. The applicable standards are addressed below: Streets: Improvements: Section 18.810.030.A.1 states that streets within a development and streets adjacent shall be improved in accordance with the TDC standards. Section 18.810.030.A.2 states that any new street or additional street width planned as a portion of an existing street shall be dedicated and improved in accordance with the TDC. Minimum Rights-of-Way and Street Widths: Section 18.810.030(E) requires a local commercial/industrial street to have a 50-foot right-of-way width and a 34-foot paved section. Other improvements required may include on-street parking, sidewalks and bikeways, underground utilities, street lighting, storm drainage, and street trees. This site lies adjacent to SW Scoffins Street, which is classified as a local commercial/industrial street on the City of Tigard Transportation Plan Map. At present, there is approximately 50 feet of ROW, according to the most recent tax assessor's map. No additional dedications are necessary. SW Scoffins Street is currently fully improved adjacent to this site. No additional improvements are necessary. The applicant's plan shows that a new 25-foot wide driveway is proposed near the east boundary of the site to serve the parking area adjacent to the new addition. The driveway location meets City requirements for driveway spacing and setbacks from a property line. ENGINEERING COMMENTS SDR 2000-00017 Tualatin Valley Centers PAGE 1 Sidewalks: Section 18.810.070.A requires that sidewalks be constructed to meet City design standards and be located on both sides of arterial, collector and local residential streets. SW Scoffins Street is already improved with sidewalk adjacent to this site. Sanitary Sewers: Sewers Required: Section 18.810.090.A requires that sanitary sewer be installed to serve each new development and to connect developments to existing mains in accordance with the provisions set forth in Design and Construction Standards for Sanitary and Surface Water Management (as adopted by the Unified Sewerage Agency in 1996 and including any future revisions or amendments) and the adopted policies of the comprehensive plan. Over-sizing: Section 18.810.090.0 states that proposed sewer systems shall include consideration of additional development within the area as projected by the Comprehensive Plan. There is an existing 8-inch public sanitary sewer line located in SW Scoffins Street that can serve the new building addition. The applicant must obtain a Street Opening Permit to perform the sewer connection work in the ROW of SW Scoffins Street. Storm Drainage: General Provisions: Section 18.810.100.A states requires developers to make adequate provisions for storm water and flood water runoff. Accommodation of Upstream Drainage: Section 18.810.100.0 states that a culvert or other drainage facility shall be large enough to accommodate potential runoff from its entire upstream drainage area, whether inside or outside the development. The City Engineer shall approve the necessary size of the facility, based on the provisions of Design and Construction Standards for Sanitary and Surface Water Management (as adopted by the Unified Sewerage Agency in 2000 and including any future revisions or amendments). The applicant's plan provides new onsite catch basins and storm drainage piping to collect all onsite runoff and will allow collection of any offsite runoff that currently flows onto the site. ENGINEERING COMMENTS SDR 2000-00017 Tualatin Valley Centers PAGE 2 Effect on Downstream Drainage: Section 18.810.100.D states that where it is anticipated by the City Engineer that the additional runoff resulting from the development will overload an existing drainage facility, the Director and Engineer shall withhold approval of the development until provisions have been made for improvement of the potential condition or until provisions have been made for storage of additional runoff caused by the development in accordance with the Design and Construction Standards for Sanitary and Surface Water Management (as adopted by the Unified Sewerage agency in 2000 and including any future revisions or amendments). In 1997, the Unified Sewerage Agency (USA) completed a basin study of Fanno Creek and adopted the Fanno Creek Watershed Management Plan. Section V of that plan includes a recommendation that local governments institute a stormwater detention/effective impervious area reduction program resulting in no net increase in storm peak flows up to the 25-year event. The City will require that all new developments resulting in an increase of impervious surfaces provide onsite detention facilities, unless the development is located adjacent to Fanno Creek. For those developments adjacent to Fanno Creek, the storm water runoff will be permitted to discharge without detention. The applicant's plan proposes an onsite detention pipe to accommodate the 25- year detention requirement. The pipe concept is acceptable, but the final design should include convenient manhole access into the detention pipe for cleaning purposes. The property owner will be required to maintain this pipe. The applicant's plan also shows that their onsite stormwater runoff will be conveyed into the ROW of SW Scoffins Street. The plan shows an offsite extension of a public storm drainage line from the east. This new public storm line extension will be terminated at the site because there is a crest in the roadway adjacent to where the new addition will be constructed. In summary, the applicant's storm drainage plan is acceptable. Bikeways and Pedestrian Pathways: Bikeway Extension: Section 18.810.110.A states that developments adjoining proposed bikeways identified on the City's adopted pedestrian/bikeway plan shall include provisions for the future extension of such bikeways through the dedication of easements or right-of-way. Cost of Construction: Section 18.810.110.13 states that development permits issued for planned unit developments, conditional use permits, subdivisions, and other developments which will principally benefit from ENGINEERING COMMENTS SDR 2000-00017 Tualatin Valley Centers PAGE 3 such bikeways shall be conditioned to include the cost or construction of bikeway improvements. Minimum Width: Section 18.810.110.0 states that the minimum width for bikeways within the roadway is five feet per bicycle travel lane. Minimum width for two-way bikeways separated from the road is eight feet. Utilities: Section 18.810.120 states that all utility lines, but not limited to those required for electric, communication, lighting and cable television services and related facilities shall be placed underground, except for surface mounted transformers, surface mounted connection boxes and meter cabinets which may be placed above ground, temporary utility service facilities during construction, high capacity electric lines operating at 50,000 volts or above, and: • The developer shall make all necessary arrangements with the serving utility to provide the underground services; • The City reserves the right to approve location of all surface mounted facilities; • All underground utilities, including sanitary sewers and storm drains installed in streets by the developer, shall be constructed prior to the surfacing of the streets; and • Stubs for service connections shall be long enough to avoid disturbing the street improvements when service connections are made. Exception to Under-Grounding Requirement: Section 18.810.120.0 states that a developer shall pay a fee in-lieu of under-grounding costs when the development is proposed to take place on a street where existing utilities which are not underground will serve the development and the approval authority determines that the cost and technical difficulty of under- grounding the utilities outweighs the benefit of under-grounding in conjunction with the development. The determination shall be on a case- by-case basis. The most common, but not the only, such situation is a short frontage development for which under-grounding would result in the placement of additional poles, rather than the removal of above-ground utilities facilities. An applicant for a development which is served by utilities which are not underground and which are located across a public right-of-way from the applicant's property shall pay a fee in-lieu of under- grounding. ENGINEERING COMMENTS SDR 2000-00017 Tualatin Valley Centers PAGE 4 There are existing overhead utility lines along SW Scoffins Street. If the fee in- lieu is proposed, it is equal to $ 27.50 per lineal foot of street frontage that contains the overhead lines. The frontage along this site is 190 lineal feet; therefore the fee would be $ 5,225.00. ADDITIONAL CITY AND/OR AGENCY CONCERNS WITH STREET AND UTILITY IMPROVEMENT STANDARDS: Public Water System: There is an existing City water main in SW Scoff ins Street that can serve the new addition. The plans show that there is an existing water meter that will be used to serve the new addition. Storm Water Quality: The City has agreed to enforce Surface Water Management (SWM) regulations established by the Unified Sewerage Agency (USA) Design and Construction Standards (adopted by Resolution and Order No. 00-7) which require the construction of on-site water quality facilities. The facilities shall be designed to remove 65 percent of the phosphorus contained in 100 percent of the storm water runoff generated from newly created impervious surfaces. In addition, a maintenance plan shall be submitted indicating the frequency and method to be used in keeping the facility maintained through the year. Prior to issuance of the site permit, the applicant shall submit plans and calculations for a water quality facility that will meet the intent of the USA Design Standards. In addition, the applicant shall submit a maintenance plan for the facility that must be reviewed and approved by the City prior to construction. The applicant's plans indicate they will treat the onsite surface water runoff with two Stormwater Management catch basin filter units. These units have been approved for use on privately maintained systems, provided the owner enters into a maintenance contract with Stormwater Management. To ensure compliance with Unified Sewerage Agency design and construction standards, the applicant shall employ the design engineer responsible for the design and specifications of the private water quality facility to perform construction and visual observation of the water quality facility for compliance with the design and specifications. These inspections shall be made at significant stages throughout the project and at completion of the construction. ENGINEERING COMMENTS SDR 2000-00017 Tualatin Valley Centers PAGE 5 Prior to final building inspection, the design engineer shall provide the City of Tigard (Inspection Supervisor) with written confirmation that the water quality facility is in compliance with the design and specifications. Grading and Erosion Control: USA Design and Construction Standards also regulate erosion control to reduce the amount of sediment and other pollutants reaching the public storm and surface water system resulting from development, construction, grading, excavating, clearing, and any other activity which accelerates erosion. Per USA regulations, the applicant is required to submit an erosion control plan for City review and approval prior to issuance of City permits. Grading and erosion control plans will be required to be submitted to the Building Division prior to construction. Recommendations: THE FOLLOWING CONDITIONS SHALL BE SATISFIED PRIOR TO ISSUANCE OF THE SITE PERMIT: Submit to the Engineering Department (Brian Rager, 639-4171, ext. 318) for review and approval: Prior to issuance of a site permit, a Street Opening Permit will be required for this project to cover the new driveway, the sanitary sewer tap and the public storm drainage line extension. The applicant will need to submit five (5) copies of a proposed public improvement plan for review and approval. NOTE: these plans are in addition to any drawings required by the Building Division and should only include information relevant to the public improvements. As a part of the public improvement plan submittal, the Engineering Department shall be provided with the exact legal name, address and telephone number of the individual or corporate entity who will be responsible for executing the compliance agreement (if one is required) and providing the financial assurance for the public improvements. For example, specify if the entity is a corporation, limited partnership, LLC, etc. Also specify the state within which the entity is incorporated and provide the name of the corporate contact person. Failure to provide accurate information to the Engineering Department will delay processing of project documents. ENGINEERING COMMENTS SDR 2000-00017 Tualatin Valley Centers PAGE 6 The applicant shall provide an on-site water quality facility as required by Unified Sewerage Agency Design and Construction Standards (adopted by Resolution and Order No. 00-7). Final plans and calculations shall be submitted to the Engineering Department (Brian Rager) for review and approval prior to issuance of the site permit. In addition, a proposed maintenance plan shall be submitted along with the plans and calculations for review and approval. THE FOLLOWING CONDITIONS SHALL BE SATISFIED PRIOR TO A FINAL BUILDING INSPECTION: Submit to the Engineering Department (Brian Rager, 639-4171, ext. 318) for review and approval: Prior to a final building inspection, the applicant shall complete any work in the public right-of-way (or public easement) and obtain approval from the Engineering Department. Prior to a final building inspection, the applicant shall provide the City with as-built drawings of the public improvements as follows: 1) mylars, and 2) a diskette of the as-builts in "DWG" format, if available; otherwise "DXF" will be acceptable. Note: if the public improvement drawings were hand-drawn, then a diskette is not required. The applicant shall either place the existing overhead utility lines along SW Scoffins Street underground as a part of this project, or they shall pay the fee in-lieu of undergrounding. The fee shall be calculated by the frontage of the site that is parallel to the utility lines and will be $ 27.50 per lineal foot. If the fee option is chosen, the amount will be $ 5,225.00 and it shall be paid prior to a final building inspection. To ensure compliance with Unified Sewerage Agency design and construction standards, the applicant shall employ the design engineer responsible for the design and specifications of the private water quality facility to perform construction and visual observation of the water quality facility for compliance with the design and specifications. These inspections shall be made at significant stages, and at completion of the construction. Prior to final building inspection, the design engineer shall provide the City of Tigard (Inspection Supervisor) with written confirmation that the water quality facility is in compliance with the design and specifications. Staff Contact: Hap Watkins, Building Division. ENGINEERING COMMENTS SDR 2000-00017 Tualatin Valley Centers PAGE 7 Prior to a final building inspection, the applicant shall demonstrate that they have entered into a maintenance agreement with Stormwater Management for the proposed onsite storm water treatment facility. i:lenglbrianrlcom m entslsdrlsdr2000-00017.doc ENGINEERING COMMENTS SDR 2000-00017 Tualatin Valley Centers PAGE 8 Kenneth H. Osterman RECEIVED PLANNING Tax Consultant 8810 S.W. Scoffins Street OCT 2 ) 2000 Tigard, Oregon 97223 (503) 639-2200 CITY OF TIGARD October 20, 2000 Julia Powell Hajduk Planning Division 13125 S.W. Hall Boulevard Tigard, Oregon 97223 RE: Review of 8770 S.W. Scoffins Street plans First, let me say that Tualatin Valley Center (TVC) has been a good neighbor since we moved into our building next door to TVC in 1990. My only concern regarding the new addition is the issue of parking and school bus/taxi traffic. At present, the school buses tend to 'pile up' in the afternoon during pickup of students. This results in the buses filling up TVC's parking spaces, parking across the street behind Rite-Aid, stopping on Scoffins Street which blocks our driveway and, in the past, parking at idle in our driveway. To NC's credit, when we voiced concern about the school buses turning around in our parking lot and idling in the driveway, they erected the present cyclone fence between TVC and our driveway. This has reduced this occurrence to almost zero. We only occasionally have to ask a bus to move. (if you look at TUC's driveway, which has been resurfaced once or twice in the past 10 years, you can see our concern regarding heavy vehicle damage to our parking/driveway). So my concern is "Will we see school bus/taxi traffic increase from the current 10 to 20 per day to a number two or three times that amount which will overwhelm the street and parking capacity?" I would hope that you have addressed concerns over increased vehicle traffic, bus parking, visibility while entering onto Scoffins Street from the new driveway, etc. Yours truly, \l Ken Osterman c.c. Greg Davidson Mark Lewis UNIFIED SEWERAGE AGENCY OF WASHINGTON COUNTY MEMORANDUM DATE: October 18, 2000 TO: Julia Hajduk, City of Tigard FROM: Julia Huffman, USA dl�- SUBJECT: Tualatin Valley Center Addition, SDR 2000-00017 SANITARY SEWER The development should be provided with a means of disposal for sanitary sewer. The means of disposal should be in accordance with Unified Sewerage Agency's Design and Construction Standards. Engineer should verify that public sanitary sewer is available to uphill adjacent properties, or extend service as required by R&O 00-7. STORM SEWER The development should have access to public storm sewer. Engineer should verify that public storm sewer is available to uphill adjacent properties, or extend storm service as required by the R&O.

The property is bordered to the north by Scoffins and across the street by property developed with Commercial Retail uses. To the south and west, is property developed with a residential mobile home park. To the east is a sin le-family residence. All of the surrounding properties are zoned Central Business District(CBD ). Site Information and Proposal Description: The site consists of the existing 8,056 square foot facility and an existing single-family structure which is proposed to be demolished. The proposal is to construct a 12,036 square foot addition onto the existing facility to create a 20,092 square foot facility. The site will have access to shared parking on the parking lot across Scoffins Street which is part of the Rite Aid shopping center rear parking lot.

COMMENTS FROM PROPERTY OWNERS WITHIN 500 FEET The Tigard Development Code requires that property owners within 500 feet of the subject site be notified of the proposal and be given the opportunity to provide written comments prior to a decision being made. Staff received written concerns which are summarized below. Copies of letters submitted are in the public record and are available for review at the City. One individual wrote with concerns about existing traffic congestion at the site due to school busses, taxis and vans waiting to pick children up and dropping them off. It was stated that currently, Tualatin Valley Center parking spaces fill up which forces parking on the street, in the Rite-aid shopping center and blocking neighboring driveways. The concern is that the addition will result in more people coming to the site which will increase traffic congestion. An additional concern is visibility while entering onto Scoffins Street from the new driveway. Staff Response: Traffic will be addressed further in this decision under street and utility improvement standards. While the number of people coming to the site may increase, the design and layout of theparking will significantly Increase the maneuverability of vehicles on-site. The applicant will be providing a one-way circular route around the building with loading towards the rear of the building. The applicant has also obtained permission to use a portion of the Rite-Aid shopping center for parking. Vision clearance has been addressed and is discussed in detail further in this decision. Staff has reviewed the proposal with these concerns in mind and has imposed conditions necessary to address the criteria, as well as, the concerns mentioned above. SECTION V.

Applicable Development Code Standards The Site development Review approval standards require that a development proposal be found to be consistent with the various standards of the Community Development Code. The applicable criteria in this case are Chapters 18.360, 18.390, 18.520, 18.705, 18.745, 18.755, 18.765, 18.790, 18.795, and 18.810. The proposal's consistency with these Code Chapters is reviewed in the following sections. The proposal contains no elements related to the following Development Code Chapters which are also listed under Section 18.360.090.A.1 : 18.350 (Planned Developments), 18.715 (Density Computations), or 18.750 (Manufactured/Mobile Home Regulations) These Chapters are, therefore, found to be inapplicable as approval standards, and are not discussed In this decision. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 5 OF 22 Access Egress and Circulation (18.705): Walkways: On-site pedestrian walkways shall comply with the following standards: Walkways shall extend from theground floor entrances or from the ground floor landing of stairs, ramps, or elevators of all commercial, institutional, and industrial uses, to the streets which provide the required access and egress. Walkways shall provide convenient connections between buildings in multi-building commercial, institutional, and industrial complexes. Unless impractical, walkways shall be constructed between new and existing developments and neighboring developments; The plans submitted by the applicant indicate that a walkway will be provided from street to the building entrance. Wherever required walkways cross vehicle access driveways or parking lots, such crossings shall be designed and located for pedestrian safety. Required walkways shall be physically separated from motor vehicle traffic and parking by either a minimum 6-inch vertical separation (curbed) or a minimum 3-foot horizontal separation, except that pedestrian crossings of traffic aisles are permitted for distances no greater than 36 feet if appropriate landscaping, pavement markings, or contrasting pavement materials are used. Walkways shall be a minimum of four feet in width, exclusive of vehicle overhangs and obstructions such as mailboxes, benches, bicycle racks, and sign posts, and shall be in compliance with ADA standards; The proposed walkway location crosses the parking lot access aisle. The section crossing the parking lot access aisle is 28 feet and will be marked with pavement striping, thus satisfying this criterion. Required walkways shall be paved with hard surfaced materials such as concrete, asphalt, stone, brick, etc. Walkways may be required to be lighted and/or signed as needed for safety purposes. Soft-surfaced public use pathways may be provided only if such pathways are provided in addition to required pathways. The entire parking lot will be paved with asphalt and the remaining portion of the walkway will be paved with concrete, therefore, this standard is met. Minimum Access Requirements for Commercial and Industrial Use: Section 18.705.030.1 provides the minimum access requirements for commercial and industrial uses: Table 18.705.3 indicates that the required access width for developments with less than 100 parking spaces is one 30 foot access point with 24 feet of pavement. Vehicular access shall be provided to commercial or industrial uses, and shall be located to within 50 feet of the primary ground floor entrances; additional requirements for truck traffic may be placed as conditions of site development review. The development will have less than 100 parking spaces and has 2 points of access into the parking lot. Both accesses have 24 feet of pavement. FINDING: Based on the analysis above, the access and egress standards have been satisfied. Landscaping and Screening (18.745 Street Trees: Section 18.745.040 states that all development projects fronting on a public street or a private drive more than 100 feet in length shall be required to plant street trees in accordance with Section 18.745.040.0 Section 18.745.040.0 requires that street trees be spaced between 20 and 40 feet apart depending on the size classification of the tree at maturity (small, medium or large). Street trees are existing in front of the existing facility and the applicant has proposed to plant 2 Sunburst Locust trees spaced 30 feet on center. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 6 OF 22 Buffering and Screening: Section 18.745 Tables 1 & 2 state that a 10-20 foot buffer is required between a proposed office use and existing residential uses and a 6-10 foot buffer is required between parking lots and residential uses. The property to the east, west and south are developed with residential properties. The property to the west and south was developed residential as a mobile home park in 1979 when the existing facility was originally constructed. Because there is no change on this portion of the site and it was approved with the current landscaping buffer, no additional buffer will be required in this area. A 10-20 foot buffer is required adjacent to the residential uses abutting the area of expansion. The buffer width adjacent to the area of expansion on the south and east Is no less than 11 feet and as large as 21 feet. There is an existing dense hedge adjacent to the southern property line, however, because the buffer width is only 10 feet, the landscape standard has not been met. Staff will not require a wall to be constructed because doing so would damage the existing mature hedge. The applicant must, however, submit a revised landscape plan that shows at least 10, five-gallon or 20, one-gallon shrubs for every 1,000 square feet of required buffer and a row of trees spaced in accordance with the standards along both the south and east property lines. Screening: Special Provisions: Section 18.745.050.E requires the screening of parkin and loading areas. Landscaped U areas shall include special design features, which effectively screen the parking lot areas from view. Planting materials to be installed should achieve a relative balance between low lying and vertical shrubbery and trees. Trees shall be planted in landscaped islands in all parking areas, and shall be equally distributed on the basis of one (1) tree for each seven (7) parking spaces in order to provide a canopy effect. The minimum dimension on the landscape islands shall be three (3) feet wide and the landscaping shall be protected from vehicular damage by some form of wheel guard or curb. If the applicant complies with the condition listed above for buffering and screening, the parking lot screening standard will also be met along the property lines. The landscape plan does not show that landscaping will be provided adjacent to the street which willprovide a balance of low lying and vertical shrubbery to effectively screen the parking lot (up to 3 feet) from view. The applicant's plans provide for new parking lot trees within the new parking lot areas with one tree for at least every 7 parking spaces. Screening of service facilities. Except for one-family and two-family dwellings, any refuse container or disposal area and service facilities such as gas meters and air conditioners which would otherwise be visible from a public street, customer or resident parking area, any public facility or any residential area shall be screened from view by placement of a solid wood fence or masonry wall between five and eight feet in height. All refuse materials shall be contained within the screened area; The applicant's plans do not show the location of service facilities, therefore, staff can not confirm that these areas will be screened in accordance with the standards. Screening of refuse containers. Except for one- and two-family dwellings, any refuse container or refuse collection area which would be visible from a public street, parking lot, residential or commercial area, or any public facility such as a school or park shall be screened or enclosed from view by placement of a solid wood fence, masonry wall or evergreen hedge. All refuse shall be contained within the screened area. The applicant's plans do not clearly show the refuse container will be screened. The existing refuse containers are not screened but are located in the back of the site. The applicant must submit a plan that clearly shows the trash enclosure will be screened. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 7 OF 22 FINDING: Based on the analysis above, the landscaping and screening standards have not been fully met. If the applicant complies with the conditions listed below, the standards will be met. CONDITIONS: Submit a revised landscape plan that shows at least 10, five-gallon or 20, one-gallon shrubs for every 1,000 square feet of required buffer and a row of trees spaced in accordance with the standards along both the south and east property lines. The landscape plan must also show a 6-foot fence will be installed along the east property line, adjacent to the residential use. Submit a revised plan that shows that service facilities (gas meters, air conditioners, etc.) will be screened from view. Submit a revised plan that clearly shows the trash enclosure will be screened by a 6-foot wood fence. Mixed Solid Waste and Recyclables Storage (18.755): Chapter 18.755 requires that new construction incorporates functional and adequate space for on-site storage and efficient collection of mixed solid waste and source separated Recyclables prior to pick-up and removal by haulers. The applicant must choose one (1) of the following four (4) methods to demonstrate compliance: Minimum Standard, Waste Assessment, Comprehensive Recycling Plan, or Franchised Hauler Review and Sign-Off. The applicant will have to submit evidence or a plan that indicates compliance with this section. The applicant's narrative does not address mixed solid waste and recyclable storage. The site plan shows the location of the proposed trash enclosure, but there has been no evidence that the size and location of the proposed trash enclosure meets any of the options available. The applicant must provide evidence that the size and location meets one of the 4 compliance methods listed above. Location standards. To encourage its use, the storage area for source-separated recyclable shall be co- located with the storage area for residual mixed solid waste; Indoor and outdoor storage areas shall comply with Uniform Building and Fire Code requirements; Storage area space requirements can be satisfied with a single location or multiple locations, and can combine both interior and exterior locations; Exterior storage areas can be located within interior side yard or rear yard areas. Exterior storage areas shall not be located within a required front yard setback or in a yard adjacent to a public or private street; Exterior storage areas shall be located in central and visible locations on a site to enhance security for users; Exterior storage areas can be located in a parking area, if the proposed use provides at least the minimum number of parking spaces required for the use after deducting the area used for storage. Storage areas shall be appropriately screened according to the provisions in 18.755.050 C, design standards; The storage area shall be accessible for collection vehicles and located so that the storage area will not obstruct pedestrian or vehicle traffic movement on the site or on public streets adjacent to the site. The location proposed is in the rear of the building and is not adjacent to a public or private street. While the proposed location is not within any required parking areas, It appears that it will only be accessible through a parking space. The location must be oriented so that It can be serviced without the need for service trucks to utilize parking spaces. There is no detail indicating that the refuse containers will be screened by a 6-foot wood fence. The waste hauler has not signed off on the location, therefore, staff can not confirm that the location is accessible to their trucks and meets their locational needs. The applicant must revise the location so it is oriented in such a way that service trucks will not have to utilize parking spaces to service the trash. The applicant has been conditioned previously to screen the trash enclosure. The applicant must submit written sign-off from the waste hauler that the location is accessible to their trucks. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 8 OF 22 Design standards. The dimensions of the storage area shall accommodate containers consistent with current methods of local collection; Storage containers shall meet Uniform Fire Code standards and be made and covered with waterproof materials or situated in a covered area; Exterior storage areas shall be enclosed by a sight-obscuring fence wall, or hedge at least six feet in height. Gate openings which allow access to users and haulers shall be provided. Gate openings for haulers shall be a minimum of 10 feet wide and shall be capable of being secured in a closed and open position; Storage area(s) and containers shall be clearly labeled to indicate the type of materials accepted. The applicant has not submitted detail of the trash enclosure or refuse container. The applicant must submit details addressing the design standards in order for Staff to determine that this standard has been met. FINDING: Because the applicant has not provided evidence that the mixed solid waste and recyclables storage location is accessible to waste hauler vehicles and staff, this standard has not been met. If the applicant complies with the condition listed below, the standards will be met. CONDITIONS: Submit information indicating how the proposed trash enclosure meets one of the 4 compliance methods listed In Chapter 18.755. Revise the location so it is oriented in such a way that service trucks will not have to utilize parking spaces to service the trash. Submit confirmation from the waste hauler that the location of the proposed receptacle is accessible to their vehicles and staff. The applicant must submit details addressing the trash enclosure design standards in order for Staff to determine that the standards will be met. Off-Street Parking and Loadina (18.765): Preferential long-term carpoo /vanpool parking: Parking lots providing in excess of 20 long-term parking spaces shall provide preferential long-term carpool and vanpool parking for employees, students and other regular visitors to the site. At least 5% of total long-term parkingg spaces shall be reserved for carpool/vanpool use. Preferential parking for carpools/vanpools shall be closer to the main entrances of the building than any other employee or student parking except parking spaces designated for use by the disabled. Preferential carpool/vanpool spaces shall be full-sized per requirements in Section 18.765.040N and shall be clearly designated for use only by carpools and vanpools between 7:00 AM and 5:30 PM Monday through Friday. The plans provide for more than 20 parking spaces, therefore, carpool/vanpool parking is required. The narrative does not address carpool parking requirements The applicant must provide at least 5% carpool spaces based on the number provided on-site. Because the number of spaces provided on-site will change as a result of conditions within this decision, staff can not state the exact number of carpool spaces required. The applicant will be conditioned to designate (with pavement marking and/or signs) at least 5% of the spaces as carpool. Disabled-accessible parking: All parking areas shall be provided with the required number of parking spaces for disabled persons as specified by the State of Oregon Uniform Building Code and federal standards. Such parking spaces shall be sized, signed and marked as required by these regulations. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 9 OF 22 The applicant has shown 40 parking spaces on-site (with additional parking to be provided via a shared parking agreement), therefore, 2 ADA handicap spaces are required, one (1) of which is van accessible (9 feet wide with and 8-foot aisle). The applicant's site plan (sheet SD3) shows 2 spaces will be marked as ADA accessible. Both spaces are van accessible. Access Drives: With regard to access to public streets from off-street parking: access drives from the street to off-street parking or loading areas shall be designed and constructed to facilitate the flow of traffic and provide maximum safety for pedestrian and vehicular traffic on the site- the number and size of access drives shall be in accordance with the requirements of dhapter, 18.705 Access Egress and Circulation; access drives shall be clearly and permanently marked and defined through use of rails, fences, walls or other barriers or markers on frontage.not occupied by service drives; access drives shall have a minimum vision clearance in accordance with Chapter 18.795, Visual Clearance; access drives shall be improved with an asphalt or concrete surface; and excludingy single-family and duplex residences, except as provided by Subsection 18.810.030.x, groups of two or more parking spaces shall be served by a service drive so that no backing movements or other maneuvering within a street or other public right-of-way will be required. The driveway andparking will be asphalted in accordance with the requirements. The number and size of the access drives is regulated by the standards specified in Section 18.705.030 and has been discussed previously in this decision. Vision clearance will be addressed further in this decision. Loading/Unloading Driveways: A driveway designed for continuous forward flow of passenger vehicles for the purpose of loading and unloading passengers shall be located on the site of any school or other meeting place which is designed to accommodate more than 25 people at one time. Staff received comments that there is currently a problem with vehicles coming to drop students off and pick them up. While this will be alleviated slightly by the new driveway layout, the applicant still must designate a location, outside of the required aisle width, to provide for dropping off and picking up of students. Staff has determined that this is feasible if the access aisle is designated one-way as will be discussed further in this decision. A condition is necessary in order for this standard to be fully met. Pedestrian Access: Pedestrian access through parking lots shall be provided in accordance with Section 18.705.030.F. Where a parking area or other vehicle area has a drop-off grade separation, the property owner shall install a wall, railing, or other barrier which will prevent a slow-moving vehicle or driverless vehicle from escaping such area and which will prevent pedestrians from walking over drop-off edges. Pedestrian access has been discussed previously in this decision. Parking Lot Striping: Except for single-family and duplex residences, any area intended to be used to meet the off-street parking requiremerits as contained in this Chapter shall have all parking spaces clearly marked; and all interior drives and access aisles shall be clearly marked and signed to show direction of flow and maintain vehicular and pedestrian safety. The plans submitted show the parking spaces on-site will be clearly marked with striping. The site plan shows the southern portion of the drive to the rear of the building will be one-way and marked accordingly. As will be discussed in more detail further in this decision, the northern access aisle serving the rear of the site must be marked one-way as well due to the aisle width of only 18 feet. In addition, signage is necessary at the entrance to the one-way drive indicating "exit only" and "entrance only". A site visit revealed the existing striping on the lot across the street is basically non-existent. In order to be permitted to use this parking as part of the shared parking, the lot must be striped with the required parking dimensions. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 10 OF 22 Wheel Stops: Parking spaces along the boundaries of a parking lot or adjacent to interior landscaped areas or sidewalks shall be provided with a wheel stop at least four inches high located three feet back from the front of the parking stall. The front three feet of the parking stall may be concrete, asphalt or low lying landscape material that does not exceed the height of the wheel stop. This area cannot be calculated to meet landscaping or sidewalk requirements. While the applicant's vicinity map dated October 6, 2000 shows wheel stops, the site plan set dated July 6, 2000 does not show wheel stops will be installed. Wheel stops are required where the parking abuts walkways and landscaping areas. If curbs are installed adjacent to the landscape areas, the vehicle may overhang into the landscape area provided the landscaping is low growing and the 3 foot area of vehicle overhang is excluded from the landscape percentage calculations. The applicant must submit revised plans that show wheel stops will be provided where the parking abuts landscaping and walkways or that shows the 3 foot landscape strip adjacent to parking will be planted with low lying shrubbery and is excluded from the landscape percentage. Space and Aisle Dimensions: Section 18.765.040.N states that: "except as modified for angled parking in Figures 18.765.1 and 18.765.2 the minimum dimensions for parking spaces are: 8.5 feet x 18.5 feet for a standard space and 7.5 feet x 16.5 feet for a compact space; aisles accommodating two direction traffic, or allowing access from both ends, shall be 24 feet in width. The site plan dated July 26, 2000 shows 39 parking spaces provided on-site, whereas, the vicinity map dated October 6, 2000 shows 40. Both of these plans have parking spaces that do not provide the adequate space and aisle dimensions. Staff's comments are based on the site plan as opposed to the vicinity map. All of the 90 degree parking spaces are dimensioned adequately and meet the aisle dimension standards of 24 feet. The parallel spaces along the northern property line, however, are of concern. The Code does not have dimensional criteria for parallel parking spaces. The Engineering Department uses the Manual for Uniform Traffic Control Devices (MUTCD) for parallel parking on streets. If using the MUTCD as a guide, the required minimum length for parallel parking spaces is 20 feet by 8 feet. The applicant has shown the spaces will be 20 feet in length and 8'6" In width. The parallel parking space closest to the street creates an access aisle width of only 18 feet which Is not adequate for 2-way traffic. Because the driveway is circular, the northern access drive could be designed as one-way, thus alleviating the access aisle width issue. The parallel parking space furthest from the street is not adequate because it provides no maneuvering room to pull into and out of the parking space. The proper way to parallel park is to pull up and then back Into the space, however, because of the layout of the parking lot, it Is not possible to do that for this proposed space. This space does not exist on the current site and must be eliminated from the site plans. The applicant attempted to show an additional parking space closer to the street on the vicinity plan, however, this would result in an access aisle that Is only 11 feet wide. The applicant must revise the plan to provide for parking spaces that meet the access aisle and dimension requirements and also provides for necessarymaneuvering for vehicles to get into the parkin spaces. The Code allows off-street arking to be located within 200 feet of the building that they are required to serve. The applicant has indicated that they have a joint parking agreement with the lot across the street, evidence of which will be conditioned within this decision. Because this parking lot is within 200 feet of the building this parking may be used and the parking on-site may be reduced in order to meet the other conditions of approval. Bicycle Parkin Location and Access: Section 18.765050 states bicycle parking areas shall be provided at locations within 50 feet of primary entrances to structures; bicycle parking areas shall not be located within parking aisles, landscape areas or pedestrian ways; outdoor bicycle parking shall be visible from on-site buildings and/or the street. When the bicycle parking area is not visible from the street, directional signs shall be used to located the parking area; and bicycle parking may be located inside a building on a floor which has an outdoor entrance open for use and floor location which does not require the bicyclist to use stairs to gain access to the space. Exceptions may be made to the latter requirement for parking on upper stories within a multi-story residential building. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 11 OF 22 The plan shows a 10 space bicycle rack will be provided near the main entrance of the building within 50 feet of the building entrance. Bicycle Parking Design Requirements: Section 18.765.050.C. The following design requirements apply to the installation of bicycle racks: The racks required for required bicycle parking spaces shall ensure that bicycles may be securely locked to them without undue inconvenience. Provision of bicycle lockers for long-term (employee) parking is encouraged but not required; bicycle racks must be securely anchored to the ground, wall or other structure; bicycle parking spaces shall be at least 21/2 feet by six feet long, and, when covered, with a vertical clearance of seven feet. An access aisle of at least five feet wide shall be provided and maintained beside or between each row of bicycle parking; each required bicycle parking space must be accessible without moving another bicycle; required bicycle parking spaces may not be rented or leased except where required motor vehicle parking is rented or leased. At-cost or deposit fees for bicycle parking are exempt from this requirement; and areas set aside for required bicycle parking must be clearly reserved for bicycle parking only. Outdoor bicycle parking facilities shall be surfaced with a hard surfaced material, i.e., pavers, asphalt, concrete or similar material. This surface must be designed to remain well drained. The applicant has not provided a detail of the bike rack to be used, therefore, staff is unable to confirm that this standard is met. Minimum Bicycle Parking Requirements: The total number of required bicycle parking spaces for each use is specified in Table 18.765.2 in Section 18.765.070.H. In no case shall there be less than two bicycle parking spaces. Table 18.765.2 states that for Medical Office Uses, .4 bicycle parking spaces are required for every 1 ,000 square feet of gross floor area, therefore, 8 bicycle parking spaces must be provided. The applicant's plan indicates 10 bicycle spaces will be provided near the main building entrance. Provided the applicant complies with the condition previously discussed for bicycle parking design this standard will be met. Minimum Off-Street Parking: Section 18.765.070.H states that the minimum and maximum parking shall be as required in Table 18.765.2. Table 18.765.2 states that the minimum parking for a Medical Office Use is 3.9 spaces per 1000 square feet and the maximum is 98 parking spaces per 1000 square feet (Parking Zone A). The applicant is, therefore, required to provide between 78 and 98 parking spaces based on the total building square footage. The Site Plan (sheet SD3) shows 39 parking spaces, however, the Vicinity map (Sheet SD1.1) shows 40 spaces on-site and 15 additional spaces across the street. The Code permits shared parking arrangements when the shared parking is within 200 feet of the use, and the parking is in excess of the required parking for the site providing the shared parking. The shared parking area is behind the existing Rite-Aid shopping center. The Rite-Aid Shopping center is required to have 265 parking spaces. There are currently 288 parking spaces in front of the shopping center and 70 spaces in the rear. Because the shopping center has more parking than is required for the use, the Tualatin Valley Center may utilize some of the parking in the rear of the shopping center. The shopping center parking lot is within 200 feet of the site. While the Vicinity Map shows 40 arking spaces, the dimensions will not meet the criteria (as discussed in detail previously in this decision). The applicant has been conditioned to meet the dimensional requirements for the 40 required parking spaces on-site. In addition, the applicant utilized general office parking requirements instead of medical office parking requirements, therefore, the applicant must nave access to 38 parking spaces on the Rite-Aid shopping center site instead of the 15 previously proposed. While the applicant submitted a written agreement from a representative of the Rite-Aid shopping center indicating that they may use their excess parking, this agreement must be formalized and recorded so that it is binding on the property to insure that the shopping center can not remove the shared parking agreement and thus bring the Tualatin Valley Center site into non-compliance. NOTICE OF TYPE 11 DECISION SDR2000-000171TUALATIN VALLEY CENTER ADDITION PAGE 12 OF 22 Off-Street Loading Spaces: Commercial, industrial and institutional buildings or structures to be built or altered which receive and distribute material or merchandise by truck shall provide and maintain off-street loading and maneuvering space as follows: A minimum of one loading space is required for buildings with 10,000 gross square feet or more; A minimum of two loading spaces for buildings with 40,000 gross square feet or more. The building will be over 10,000 square feet, thus requiring a loading space. The site plan shows a loading space, however, it is located in the middle of the access aisle and, therefore, can not be approved. The applicant must submit a revised plan that provides for a loading space which will not obstruct traffic or take up required parking. FINDING: Based on the analysis above, the off-street parking and loading standards have not been fully met, however, if the applicant complies with the conditions listed below, the standards will be fully met. CONDITIONS: Submit a revised plan that clearly shows at least 5% of the parking spaces on-site will be designated as carpool parking spaces. Submit a revised plan that shows the location of a drop-off and pick-up loading zone that is outside of the required aisle width. Submit a revised plan that shows the northern access aisle to the rear of the lot will be marked as one-way. Staff recommends that this be designated one-way going out and the southern access drive be designated one-way going In. The plans must indicate signage, as well as, pavement markings will be used. Prior to final inspection and occupancy, the parking used as part of the shared parking in the Rite-Aid parking lot must be re-striped so that the spaces are clearly visible. Submit a revisedplan that shows wheel stops will be installed where the parking abuts walkways and landscaping. Alternatively, the plan may show a curb and low growing landscaping where the parking abuts landscaping as long as the applicant provides evidence that the landscape percentages are met after excluding the 3-foot overhang area from the landscape calculations. Submit a revisedplan that provides for parking spaces that meets the access aisle and dimensions requirements and also provides for necessary maneuvering for vehicles to get into the parking spaces. Submit details of the bicycle rack to be used. Submit a copy of a formal and binding (recorded) agreement with the Rite-Aid shopping center indicating that Tualatin Valley Center may share at least 38 (or more as needed to total 78 over both parking lots) parking spaces. Submit a revised plans that provides for a loading space that does not block vehicle access within the parking lot or takes up required parking. Si ns (18.780): Chapter 18.780.130.D lists the type of allowable signs and sign area permitted in the CBD Zoning District. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 13 OF 22 The applicant has one existing sign. The narrative indicates that the applicant would like to install an additional sign at the new driveway entrance to allow for better visibility in order to avoid potential problems with cars braking suddenly to turn into the site. The sign code does not allow for more than 1 sign in this zone unless it has multiple street frontages. The existing sign is non-conforming because it is within the vision clearance area. Staff is requiring a condition to alter the location of the existing sign to increase visibility from both directions. The new sign location will be reviewed through a separate permit process administered by the Planning and Engineering Permit Technicians. FINDING: Because a sign permit has not been obtained for the re-location of the sign so that it is outside of vision clearance areas, this standard has not been met. If the applicant obtains a sign permit, this standard will be satisfied. CONDITION: Prior to final building inspection, apply for and receive a sign permit to alter the location of the existing sign so that it is not within a vision clearance area. Tree Removal (18.790 Section 18.790.030 requires that a tree plan for the planting, removal and protection of trees prepared b a certified arborist shall be provided with a site development review application. The Yree.plan shall include identification of all existing trees, identification of a program to save existing trees or mitigate tree removal over 12 inches in caliper, which trees are to be removed, protection program defining standards and methods that will be used by the applicant to protect trees during and after construction. The applicant has submitted a landscape plan that shows trees to be removed. They have also submitted a tree preservation and mitigation plan, however, the two plans submitted do not match. The tree preservation and mitigation plan, preppared by a certified arborist, refers to a map that is not attached. It indicates that there are 15 trees on the site over 12 inches that must be removed. The landscape plan (sheet SD4) shows only 11 trees that are to be removed and the numbers do not correspond to the numbers on the plan prepared by the arborist. The applicant must submit a plan that clearly shows the size and location of all trees in the site over 12 inches and those that are to be removed. Mitigation will be required based on the number of trees and inches removed. FINDING: Based on the analysis above, staff can not confirm that the tree removal standards are met. f the applicant complies with the conditions listed below, the standards will be met. CONDITIONS: Submit a plan and arborist report that clearly shows the number, location, and size of all existing trees on the site and the number of 12 inch trees that will be removed. Based on the percentage of trees to be removed versus retained, submit a mitigation plan for the caliper inches removed indicating whether planting will be done on-site, off-site, or by paying the fee in-lieu. Prior to any site work, install tree protection measures for trees that are to be retained. Prior to final inspection, tree mitigation must be completed. Visual Clearance Areas (18.795 Chapter 18.795 requires that a clear vision area shall be maintained on the corners of all property adjacent to intersecting right-of-ways or the intersection of a public street and a private driveway. A clear vision area shall contain no vehicle, hedge, planting, fence, wall structure, or temporary or permanent obstruction exceeding three (3) feet in height. The code provides that obstructions that may be located in this area shall be visually clear between three �3) and eight (8) feet in height (8) (trees may be placed within this area provided that a I branches below eight (8) feet are removed). A visual clearance area is the triangular area formed by measuring a 30-foot distance along the street right- of-way and the driveway, and then connecting these two (2), 30-foot distance points with a straight line. NOTICE OF TYPE 11 DECISION SDR2000-00017fTUALATIN VALLEY CENTER ADDITION PAGE 14 OF 22 The site plan does not identify the vision clearance areas. The narrative indicates that the standards are met, however, when staff scaled the vision clearance areas off on the plans, parking, landscaping and the existing and proposed signs are located within these areas. The plans must be revised to show no parking and only low growing vegetation will be located within the vision clearance area adjacent to the easternmost driveway and to show the existing sign will be re-located as conditioned previously. FINDING: Based on the analysis above, the vision clearance standards have been not been met. If the applicant complies with the condition below, the standards will be met. CONDITION: Submit a revised landscape plan that shows no parking or vegetation will be located in the vision clearance area at the easternmost driveway that exceed 3 feet in height. B. Specific Site Development Review Approval Standards Section 18.360.090(A)(2) through 18.360.090(A)(15) provides additional Site Development Review approval standards not necessarily covered by the provisions of the previously listed sections. These additional standards are addressed immediately below with the following exceptions: The proposal contains no elements related to the provisions of the following and are, therefore, found to be inapplicable as approval standards: 18.360.090.3 (Exterior Elevations);); 18.360.090.5 (Privacy and Noise: Multi-family or Group Living Uses); 18.360.090.6 (Private Outdoor Areas: Multi-family Use); 18.360.090.7 (Shared Outdoor Recreation Areas: Multi-family Use); and 18.360.090.9 (Demarcation of Spaces). The following sections were discussed previously in this decision and, therefore, will not be addressed in this section: 18.360.090.4Buffering Screening and Compatibility Between Adjoining Uses; 18.360.090.13 Parking); 18. 60.090.14 (Landscaping); 18.360.090.15 (Drainage); and 18.360.090.14 Provision for the Disabled). Relationship to the Natural and Physical Environment: Buildings shall be: located to preserve existing trees, topography and natural drainage where possible based upon existing site conditions; located in areas not subject to ground slumping or sliding; located to provide adequate distance between adjoining buildings for adequate light, air circulation, and fire-fighting; and oriented with consideration for sun and wind. Trees shall be preserved to the extent possible. Replacement of trees is subject to the requirements of Chapter 18.790, Tree Removal. Because the proposal is an addition onto an existing building the location can not be altered. The proposal will retain as many trees on-site as possible. The area is not subject to slumping or sliding and there are no known natural drainage areas on the site. The Fire Department has reviewed the proposal and provided comments which have been incorporated into this decision. They did not raise any concerns with the building location, orientation or design. FINDING: Based on the analysis above, this standard has been satisfied. Crime Prevention and Safety: Windows shall be located so that areas vulnerable to crime can be surveyed by the occupants; Interior laundry and service areas shall be located in a way that they can be observed by others; Mail boxes shall be located in lighted areas having vehicular or pedestrian traffic; NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 15 OF 22 The exterior lighting levels shall be selected and the angles shall be oriented towards areas vulnerable to crime; and Light fixtures shall be provided in areas having heavy pedestrian or vehicular traffic and in potentially dangerous areas such as parking lots, stairs, ramps and abru�t grade changes. Fixtures shall be placed at a height so that light patterns overrap at a height of seven feet, which is sufficient to illuminate a person. Windows are oriented towards the parking lots. The City of Tigard Police Department has reviewed this project and has requested that a lighting plan be provided for their review. Because the Police Department has indicated that a lighting plan is needed, the Crime Prevention and Safety standards have not been fully met. If the applicant submits a lighting plan for review and appproval to the Police Department, the standards will be met. Please note that the lighting must be directed away from the residential properties. FINDING: Because the Police Department has indicated that they must see a lighting plan, this standard has not been met. If the applicant complies with the condition specified below, the standard will be met. CONDITION: Submit a lighting plan to the Police Department for review and approval. The lighting plan must also show that lights will be directed away from the residential properties and the public right-of-way. Public Transit: Provisions within the plan shall be included for providing for transit if the development proposal is adjacent to existing or proposed transit route; the requirements for transit facilities shall be based on: the location of other transit facilities in the area; and the size and type of the proposal. The following facilities may be required after City and Tri-Met review: bus stop shelters; turnouts for buses; and connecting paths to the shelters. The site has frontage on SW Scoffins which is within a '/4 mile of a Tri-met transit route. Staff sent a request for comments to Tri-met, however, they did not respond with a request for the applicant to provide additional transit facilities along the frontage. FINDING: Based on the analysis above, this standard is satisfied. 100-year floodplain Where landfill and/or development is allowed within and adjacent to the 100-year floodplain, the City shall require consideration of the dedication of sufficient open land area for greenway adjoining and within the floodplain. This area shall include portions at a suitable elevation for the construction of a pedestrian/bicycle pathway within the floodplain in accordance with the adopted pedestrian/ bicycle plan. The property is not within or adjacent to the 100-year floodplain, therefore, this standard does not apply. FINDING: Based on the information above, this standard does not apply. Provisions of the Underlying Zone: All of the provisions and regulations of the underlying zone shall app/y unless modified by other sections or this title, e.g., Planned Developments, Chapter 18.350; or a variance or adjustment granted under Chapter 18.370. Use Classification: The applicant is proposing to construct an addition onto the existing day treatment counseling facility The zone is CBD. The proposed use would be considered a counseling office which is allowed in this zone. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 16 OF 22 Dimensional Requirements: The following table compares the dimensional requirements with the proposed requirements. As can be seen from the table, the proposal fully complies with the dimensional requirements.

FINDING: Based on the analysis above, the provisions of the underlying zone are met. Street And Utility Improvement Standards (18.810) Street And Utility Improvements Standards (Section 18.810): Chapter 18.810 provides construction standards for the implementation of public and private facilities and utilities such as streets, sewers, and drainage. The applicable standards are addressed below: Streets: Improvements: Section 18.810.030.A.1 states that streets within a development and streets adjacent shall be improved in accordance with the TDC standards. Section 18.810.030.A.2 states that any new street or additional street width planned as a portion of an existing street shall be dedicated and improved in accordance with the TDC. Minimum Rights-of-Way and Street Widths: Section 18.810.030(E) requires a local commercial/industrial street to have a 50-foot right-of-way width and a 34-foot paved section. Other improvements required may include on-street parking, sidewalks and bikeways, underground utilities, street lighting, storm drainage, and street trees. This site lies adjacent to SW Scoffins Street, which is classified as a local commercial/industrial street on the City of Tigard Transportation Plan Map. At present, there is approximately 50 feet of ROW, according to the most recent tax assessor's map. No additional dedications are necessary. SW Scoffins Street is currently fully improved adjacent to this site. No additional improvements are necessary. The applicant's plan shows that a new 25-foot wide driveway is proposed near the east boundary of the site to serve the parking area adjacent to the new addition. The driveway location meets City requirements for driveway spacing and setbacks from a property line. Sidewalks: Section 18.810.070.A requires that sidewalks be constructed to meet City design standards and be located on both sides of arterial, collector and local residential streets. SW Scoffins Street is already improved with sidewalk adjacent to this site. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 17 OF 22 Sanitary Sewers: Sewers Required: Section 18.810.090.A requires that sanitary sewer be installed to serve each new development and to connect developments to existing mains in accordance with the provisions set forth in Design and Construction Standards for Sanitary and Surface Water Management (as adopted by the Unified Sewerage Agency in 1996 and including any future revisions or amendments) and the adopted policies of the comprehensive plan. Over-sizing: Section 18.810.090.0 states that proposed sewer systems shall include consideration of additional development within the area as projected by the Comprehensive Plan. There is an existing 8-inch public sanitary sewer line located in SW Scoffins Street that can serve the new building addition. The applicant must obtain a Street Opening Permit to perform the sewer connection work in the ROW of SW Scoffins Street. Storm Drainage: General Provisions: Section 18.810.100.A states requires developers to make unoff adequate provisions for storm water and flood water r . Accommodation of Upstream Drainage: Section 18.810.100.0 states that a culvert or other drainage facility shall be large enough to accommodate potential runoff from its entire upstream drainage area, whether inside or outside the development. The City Engineer shall approve the necessary size of the facility, based on the provisions of Design and Construction Standards for Sanitary and Surface Water Management (as adopted by the Unified Sewerage Agency in 2000 and including any future revisions or amendments). The applicant's plan provides new onsite catch basins and storm drainage piping to collect all onsite runoff and will allow collection of any offsite runoff that currently flows onto the site. Effect on Downstream Drainage: Section 18.810.100.D states that where it is anticipated by the City Engineer that the additional runoff resulting from the development will overload an existing drainage facility, the Director and Engineer shall withhold approval of the development until provisions have been made for improvement of the potential condition or until provisions have been made for storage of additional runoff caused by the development in accordance with the Design and Construction Standards for Sanitary and Surface Water Management (as adopted by the Unified Sewerage agency in 2000 and including any future revisions or amendments). In 1997, the Unified Sewerage Agency (USA) completed a basin study of Fanno Creek and adopted the Fanno Creek Watershed Management Plan. Section V of that plan includes a recommendation that local governments institute a stormwater detention/effective impervious area reduction program resulting in no net increase in storm peak flows up to the 25-year event. The City will require that all new developments resulting In an increase of impervious surfaces provide onsite detention facilities, unless the development is located adjacent to Fanno Creek. For those developments adjacent to Fanno Creek, the storm water runoff will be permitted to discharge without detention. The applicant's plan proposes an onsite detention pipe to accommodate the 25-year detention requirement. The pipe concept is acceptable, but the final design should include convenient manhole access Into the detention pipe for cleaning purposes. The property owner will be required to maintain this pipe. The applicant's plan also shows that their onsite stormwater runoff will be conveyed into the ROW of SW Scoffins Street. The plan shows an offsite extension of a public storm drainage line from the east. This new public storm line extension will be terminated at the site because there is a crest in the roadway adjacent to where the new addition will be constructed. In summary, the applicant's storm drainage plan is acceptable. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 18 OF 22 Bikeways and Pedestrian Pathways: Bikeway Extension: Section 18.810.110.A states that developments adjoining proposed bikeways identified on the City's adopted pedestrian/bikewayplan shall include provisions for the future extension of such bikeways through the dedication of easements or right-of-way. The proposed development does not abut a bikeway, therefore this standard does not apply. Utilities: Section 18.810.120 states that all utility lines, but not limited to those required for electric, communication, lighting and cable television services and related facilities shall be placed underground, except for surface mounted transformers, surface mounted connection boxes and meter cabinets which may be placed above ground, temporary utility service facilities during construction, high capacity electric lines operating at 50,000 volts or above, and: The developer shall make all necessary arrangements with the serving utility to Y the underground services; The City reserves the right to approve location of all surface mounted facilities; All underground utilities, including sanitary sewers and storm drains installed in streets by the developer, shall be constructed prior to the surfacing of the streets; and Stubs for service connections shall be long enough to avoid disturbing the street improvements when service connections are made. Exception to Under-Grounding Requirement: Section 18.810.120.0 states that a developer shall pay a fee in-lieu of under,groundin.Q costs when the development is proposed to take place on a street where existing utilities which are not underground will serve the development and the approval authority determines that the cost and technical difficulty of under-grounding the utilities outweighs the benefit of under-grounding in conjunction with the development. The determination shall be on a case-by-case basis. The most common, but not the only, such situation is a short frontage development for which under-grounding would result in the placement of additional poles, rather than the removal of above-ground utilities facilities. An applicant for a development which is served by utilities which are not underground and which are located across a public right-of-way from the applicant's property shall pay a fee in-lieu of under-grounding. There are existing overhead utility lines along SW Scoffins Street. If the fee in-lieu is proposed, it is equal to $27.50 per lineal foot of street frontage that contains the overhead lines. The frontage along this site is 190 lineal feet; therefore the fee would be $5,225.00. ADDITIONAL CITY AND/OR AGENCY CONCERNS WITH STREET AND UTILITY IMPROVEMENT STANDARDS: Public Water Svstem: There is an existing City water main in SW Scoffins Street that can serve the new addition. The plans show that there Is an existing water meter that will be used to serve the new addition. Storm Water Quality: The City has agreed to enforce Surface Water Management (SWM) regulations established by the Unified Sewerage Agency (USA) Desiqn and Construction Standards (adopted bar Resolution and Order No. 00- ) which require the construction of on-site water quality facilities. The facilities shall be designed to remove 65 percent of the phosphorus contained in 100percent of the storm water runoff generated from newly created impervious surfaces. In addition, a maintenance plan shall be submitted indicating the frequency and method to be used in keeping the facility maintained through the year. NOTICE OF TYPE 11 DECISION SDR2000-00017/TUALATIN VALLEY CENTER ADDITION PAGE 19 OF 22 Prior to issuance of the site permit, the applicant shall submit plans and calculations for a water quality facility that will meet the intent of the USA Design Standards. In addition, the applicant shall submit a maintenance plan for the facility that must be reviewed and approved by the City prior to construction. The applicant's plans indicate they will treat the onsite surface water runoff with two Stormwater Management catch basin filter units. These units have been approved for use on privately maintained systems, provided the owner enters into a maintenance contract with Stormwater Management. To ensure compliance with Unified Sewerage Agency design and construction standards, the applicant shall employ the design engineer responsible for the design and specifications of the private water quality facility to perform construction and visual observation of the water quality facility for compliance with the design and specifications. These inspections shall be made at significant stages throughout the project and at completion of the construction. Prior to final building inspection, the design engineer shall provide the City of Tigard (Inspection Supervisor) with written confirmation that the water quality facility is in compliance with the design and specifications. Grading and Erosion Control: USA Design and Construction Standards also regulate erosion control to reduce the Z mount of sediment and other pollutants reaching the public storm and surface water system resulting from development, construction, grading, excavating, clearing, and any other activity which accelerates erosion. Per USA regulations, the applicant is required to submit an erosion control plan for City review and approval prior to issuance of City permits. Grading and erosion control plans will be required to be submitted to the Building Division prior to construction. C. Impact Study (18.390) Section 18.360.090 states, "The Director shall make a finding with respect to each of the following criteria when approving, approving with conditions or denying an application:" Section 18.390.040 states that the applicant shallprovide an impact study to quantify the effect of development on public facilities and services. For each public facility system and type of impact, the study shall propose improvements necessary to meet City standard, and to minimize the impact of the development on the public at large, public facilities systems, and affected private property users. In situations where the Community Development Code requires the dedication of real property interests, the applicant shall either specifically concur with a requirement for public right-of-way dedication, or provide evidence that supports that the real property dedication is not roughly proportional to the projected impacts of the development. Section 18.390.040 states that when a condition of approval requires the transfer to the public of an interest in real property, the approval authority shall adopt findings which support the conclusion that the interest in real property to be transferred is roughly proportional to the impact the proposed development will have on the public. The applicant has provided an impact study addressing the project's impacts on public systems. The Washington County Traffic Impact Fee (TIF) is a mitigation measure that is required at the time of development. Based on a transportation impact study prepared by Mr. David Larson for the A-Boy Expansion/Dolan II/Resolution 95-61, TIF's are expected to recapture 32 percent of the traffic Impact of new development on the Collector and Arterial Street system. The applicant will be required to pay TIF's of approximately $55,836 based on the use proposed. NOTICE OF TYPE 11 DECISION SDR2000-000171TUALATIN VALLEY CENTER ADDITION PAGE 20 OF 22 Based on the estimate that total TIF fees cover 32 percent of the impact on major street improvements citywide, a fee that would cover 100 percent of this projects traffic Impact Is $174,487 ($55,836 divided by .32). The difference between the TIF paid, and the full impact, is considered the unmitigated Impact on the street system. The unmitigated impact of this project on the transportation system is $118,651. There is no dedication or improvement requirement for this project. SECTION VII. OTHER STAFF COMMENTS The City of Tigard Building Division has reviewed this application and offered the following comments: 1 .) Will require 3 hydrants; 2.) Existing building will require a total seismic and ADA upgrade; 3.) An elevator will be required; 4.) Existing will require energy code upgrade; 5.) Depending on use, this may be an I Division 1 .1 occupancy. Note: Applicant must contact Building Department directly regarding these comments. Any changes to the site plan as a result of building requirements must be approved by Planning. Building does not automatically route plans to Planning. The City of Tigard Operations Utility Manager has reviewed the proposal and provided the following comments: Currently, the site has two water services. One to the existing building at 8770 SW Scoffins (1" meter) and one to the proposed building to be demolished at 8750 Scoffins (5/8" x 3/4" meter). We will only allow one service for the one building. The existing 1-inch meter may not be adequate (not enough capacity) and need to be enlarged. Developer to supply fixture calculations. Also, we will require a double check valve assembly (backflow protection) be installed directly behind the water meter (customer side of meter). The City of Tigard Police Department has reviewed the proposal and offered the following comments: "Request lighting design for exterior and parking areas. No lighting is indicated on the plans". The City of Tigard Property Manager has reviewed the application and has provided no comments or objections. SECTION VIII. AGENCY COMMENTS Unified Sewerage Agency has reviewed the proposal and provided comments which were incorporated in to the body of this decision. TVF&R has reviewed the proposal and provided the following comments: 1 . Because the entire building will be provided with a central supervised automatic fire sprinkler system, the required fire flow is reduced to 1500 gpm @ 20 psi. Prior to the issuance of building permits, documentation shall be provided that indicates the minimum required fire flow Is available at the required hydrants. 2. A minimum of 3 fire hydrants is required for this project. The hydrants shall be located so that all portions of the building are within 500 feet of a hydrant. 3.

Portland, OR 97229 Dear Ms. Weyrauch: The City of Tigard has received the response to our incompleteness letter dated 8-23-00. After reviewing this information, we have determined that all outstanding items have been addressed sufficiently with the exception of the parking issue. I have spoken to your Architect regarding this issue and it is my understanding they are working on getting the additional information necessary for us to review the parking a proposed. For your information, the following information is necessary for the City to continue reviewing the proposal with fewer on-site parking spaces than required by code: Show the location of the shared off-site parking for staff to confirm that it is within 300 feet of the project site Provide a revised plan that shows at least 40 parking spaces on-site Submit a copy of a recorded shared parking agreement between the subject site and the site providing the extra parking spaces. The parking agreement must be irrevocable. Submit information for staff to confirm that the site providing the additional parking spaces has more parking than they are required to have based on their use In addition, we will need 3 additional copies of the Preliminary Stormwater Calculations plan Alternatively, you may apply for a parking adjustment to reduce the required parking on-site via a parking adjustment. This type of adjustment allows a reduction of only 20% however, and the parking provided on-site is less than 20% of the required. Once this additional information is submitted, staff will deem the application complete and schedule the project for review. The estimated time frame for review once the application is deemed complete is 6-8 weeks.

Staff has completed an initial completeness review of the project and has determined that additional information is necessary before staff can begin reviewing the request. Please submit the following in order for staff to deem the application complete: Pay for and formally apply for a parking variance. The code allows up to 20% reduction in parking if certain criteria are met. If more than 20% reduction is requested, a standard variance is required. The criteria for a standard variance are very difficult to meet and it is unlikely that staff would be able to support this in this instance because it is possible to provide the required parking (or at least more parking) on-site. You may wish to modify the proposed plan to provide enough parking to apply for a 20% reduction. In either case, additional narrative and supporting information will be necessary to justify the request. In addition, the required fee of $109 must be paid Submit a copy of the USA Service Provider letter. In accordance with the standards that became effective on February 5, 2000, this letter is required to be submitted before an application can be deemed complete. The requirement is for all applications submitted after February 5, 2000. 1 am enclosing contact-information for your reference. Provide clarification on the applicant contact information. The narrative and site plans state the contact address is 8770 SW Scoffins, however, the application form indicates that the contact address is 14600 NW Cornell Road.

The following are responses to your comments: 1. Pay for and formally apply for a parking variance. Our intent is not to request a reduction in the amount of parking provided. Based on the City of Tigard zoning we are required to provide 2.7 spaces per 1,000 square feet or 54 spaces. We also have a required 15% landscape requirement. Per section 18.765.030.B Tualatin Valley Center° may provide for spaces in excess of the required first 40 spaces up to a distance of 300 feet from the primary site." Tualatin Valley Center has an agreement with the owners of the shopping center to the north to allow Tualatin Valley Center staff to park in their lot directly across Scoffins Street. Although more parking could be located directly on site, Tualatin Valley Center would like to maximize the amount of contiguous open common space and landscaping to keep within the intent of the facility. (See 18.765 Off-street Parking and Loading pages 5-6 of the project narrative.) 2. Submit a copy of the USA service provider letter. Letter will be forwarded upon receipt.

The first concern deals with joint parking having a demand load exceeding its capacity due to peak hours being in conflict. Tualatin Valley Centers opens for business from 9:00 a.m. to 6:00 p.m., Monday thru Friday. As with most shopping malls, The Rite Aide Shopping Center has its highest use on the weekends. Therefore the peak hours are not in direct conflict. This is, in fact, the basis on which the long-standing shared parking agreement was established. The other concern relates to the size and location of the joint parking facility. At this mall there is a public parking facility in front of the mall consisting of approximately 288 spaces and a parking facility behind the mall consisting of 70 spaces which is primarily intended for employee use. The combined net square footage of leasable retail space in the mall is 71,713 square feet. The allocation ratio of 3.7 parking spaces for every 1,000 square feet of retail space, indicates that 265 spaces would be required for the use of the mall. This leaves 23 spaces unused in front and 70 spaces unused behind the mall. Therefore, Tualatin Valley Center's parking agreement to use 15 spaces in the rear lot does not impact the quantity of parking required for the shopping mall. If you have any further questions, please do not hesitate to call. Thank you, Mark D. Hinrich , Architect John W.

FINKLEA, ARCHITECT 3223 SW NAITO PARKWAY PORTLAND, OR. 97201 (503) 248-0617 TUALATIN VALLEY CENTERS - ADOLESCENT DAY TREATMENT PROGRAM I. INTRODUCTION Tualatin Valley Centers is a non-profit organization providing a variety of counseling and mental health services to clients throughout the metropolitan Portland area. In addition to its involvement in various South County sponsored programs, TVC currently operates the Adolescent Day Treatment Program, a counseling center for children, teens and their families, at 8770 SW Scoffins Street, Tigard, Oregon. This program essentially provides therapy to adolescents who are having difficulty performing academically and socially in a school environment. The ADT Program began in a facility designed for its purposes on Cornell Road. The program grew quickly and was relocated to Tigard in 1990 with the purchase of the Scoffins Street property. The type of services provided by the ADT Program are extremely valuable and in great demand. As a result, the program has now outgrown the Scoffins Street facility after over 10 years of successful operation. Since the adjacent property is available and the zoning is appropriate, Tualatin Valley Center has decided to expand the existing facility rather than move to another location, helping to maintain continuity for its clients as well as promoting an efficient use of resources by keeping new and expanding programs in close proximity. The existing facility is a two-story, 8,056 square foot, wood-framed building constructed in the 1970s. It has been remodeled for Tualatin Valley Center's use on two prior occasions. TVC recently acquired the property to the Southeast at 8750 SW Scoffins and proposes to construct a new two-story, 12,036 square foot, wood frame addition. The new structure will adjoin the existing building on its east side and will include improved amenities for parking, handicap access, vehicular and pedestrian circulation, and an outdoor recreation area for children. II. SITE DESCRIPTION Legal Description: Lots 25 & 26, "Tigard Highway Tracts," Tax Lot# 2S 1-02AA-02800 Address: 8750 & 8770 SW Scoffins Street, Tigard, Washington County, Oregon, 97223 Owner: Tualatin Valley Centers 14600 Cornell Road, Portland, Oregon 97229 Contact: Mark Lewinsohn, Director, TVADTP (503) 684-1424 The site is 47,500 square feet (1.09 acres) located in the Central Business District zone. The east property line measures 190 feet fronting on SW Scoffins Street. Two structures currently exist on the property: a two-story commercial building and a two-story wood frame house. The house is owned by Tualatin Valley Center and is used for office and counseling activities. The house will be relocated or removed to allow for construction of the new building. The topography of the site slopes down to each property line from a point near the Scoffins Street entrance of the commercial building, with a maximum change in elevation of approximately 11 feet. The site is bounded on three sides by residential properties: a single family house to the Southeast and mobile home courts to the Southwest and Northwest, all located within the CBD zone. SW Scoffins is a designated Minor Collector Street, with two lanes and a center turning lane. On-street parking is not allowed adjacent to the site frontage. SW Scoffins does not carry any Tri-Met bus routes. However, the Tigard Transit Center is nearby and Tri-Met routes #78 and # 64X run a few blocks away from the site, along SW Hall and SW Main respectively. All public utilities are currently available to the site. III. NARRATIVE RESPONSE TO COMMUNITY DEVELOPMENT CODE 18.360 SITE DEVELOPMENT REVIEW Rationale for proposed modifications per Subsection B: The proposed project will increase the gross floor area of the facility from 8,056 square feet to a total of 20,092 square feet . Per Table 18.765.2, the minimum number of parking spaces required would be 2.7 for every 1000 sq. ft., or fifty-five (55) spaces, in addition to two (2) designated disabled-accessible parking spaces. The site currently has approximately 20 parking spaces, 2 of which are designated as disabled-accessible. TVC is planning to add an additional 17 spaces, bringing the total to 35 standard spaces and 2 disabled-accessible spaces. The number of staff is expected to increase from approximately 17 to approximately 30, many of whom carpool, take public transit, or work part-time and/or staggered shifts and are not on- site simultaneously. The client base is also expected to increase, however, the children and adolescents who comprise the client base either arrive by van or are dropped off by private vehicles. Consequently, calculating the necessary number of parking spaces based strictly on square footage in this case would lead to an excessive number of spaces, most of which would remain unused. The proposed project has been designed to allow for additional parking to be added in the future should the need arise through a change of ownership or use. At this time TVC would like to limit the number of parking spaces in order to better meet the intent of the code, i.e. to ensure adequate parking and maintain the traffic carrying-capacity of the street while preserving as much area as possible for common open space and landscaping. The design of the project as proposed allows for 18% of the site to remain open space/ landscaping. 18.390 IMPACT STUDY The project as proposed is likely to have a minimal impact on the transportation system. The staff is expected to increase with a proportional increase in the number of staff that carpool or take public transit. In addition, many of the staff work part-time and/ or staggered shifts, so that additional traffic to the site would be dispersed over the course of the business day. The client base is also expected to increase. The children and adolescent clients are generally dropped off and picked up via bus, van or private vehicle at intermittent periods during the business day. The current parking and vehicular circulation on the site is such that traffic traveling on SW Scoffins Street is occasionally obstructed by vehicles entering or leaving the site or by vehicles stopping to pick-up/drop-off passengers. The proposed project will reconfigure the parking and driveways to provide for more efficient circulation as well as locating passenger pick-up/ drop-off entirely on-site, thereby alleviating problems with blocking traffic on SW Scoffins and mitigating any potential increase in the overall level of traffic to the site. There is no bicycle traffic to the facility at this time, nor is any anticipated with the proposed project, therefore, there will be no impact on the local bikeway system. The project includes its own outdoor recreation areas and since clients are confined to the site, 2 the proposed expansion will not impact the local park system. The storm water drainage system has been designed by HBH Consulting Engineers. Please see the HBH drawings and the report with preliminary sizing calculations for the drainage system will included with this Site Development Review Application. The Unified Sewerage Agency has been contacted concerning water quality & detention facility requirements. The existing building has 4 water closets, 4 lavatories, 1 shower, 2 kitchen sinks, 2 utility sinks, and 2 drinking fountains for a total of 15 fixtures. The new addition will add only the minimum 18 fixtures required by code; 6 water closets, 6 lavatories, 2 kitchen sinks, 2 utility sinks and 2 drinking fountains, bringing the total for the facility to 33 fixtures. The new addition will also be fully sprinklered, per discussions with Tualatin Valley Fire and Rescue. A water meter/ connection is located in SW Scoffins directly in front of the existing building. It may be necessary to increase the size of the supply line from this connection to accommodate the demands of the new addition. Two sanitary sewer connections are located near the site in SW Scoffins, with the system for the existing building running to the northern-most location. It is expected that the existing system will be adequate with modifications to the size and connections. HBH Consulting Engineers is reviewing the system to determine exactly what modifications are required. Most activities of the ADT Program take place inside the building during the regular weekday business hours. These activities are essentially limited to standard office and counseling interactions and rarely, if ever, generate an inordinate level of noise. The impact of any noise generated becomes even less after taking into consideration the distance from the building to the adjacent properties and structures (41' min. to closest property line). The only activities that could produce a higher level of noise would be those which take place in the outdoor recreation area, i.e. children and adolescents at play, but again that would occur only during regular weekday business hours and in appropriate weather. 18.520 COMMERCIAL ZONING DISTRICTS All Development Standards of Table 18.520.2 are met or exceeded by the proposed design of the project: Building setbacks: Scoffins Street: 73'-6" Required: 30' Rear yard: 49'-0" Required: 30' NW side yard: 41'-8" Required: 30' SE side yard: 41'-10" Required: 30' Bldg height: 30' Max. allowed: 85' Site coverage: Bldg: 23% Hardscape: 59% Total: 82% Max. allowed: 85% Landscaping: 18% Min. required: 15% 3 18.520.60 ADDITIONAL DEVELOPMENT AND DESIGN GUIDELINES SW Scoffins Street is a designated Minor Collector Street and does not carry any Tri-Met bus routes or bikeway paths. However, the Tigard Transit Center is nearby and Tri-Met routes #78 and # 64X run a short distance away from the site, along SW Hall and SW Main respectively. The main public entrances to the building are oriented to SW Scoffins, which already has sidewalks in place for use by pedestrians traveling to and from transit stops. A new pedestrian walkway will make a direct link from the main entrance to the street. Pedestrian walkways and street level windows occur along the SW Scoffins facade as well as along the NE & SE elevations of the building near the outdoor recreation areas. A bicycle parking area for a minimum of eight (8) bicycles (as required per Subsection 18.765.050) has been located adjacent to the walkway near the main public entrance to the new building. Parking areas for staff have been located along the NW & SW edges of the site with walkways leading into entrances at the side and rear of the building. Near the outdoor recreation area, the drive is held as far from the building as possible to promote the safety of the clients and allow the largest possible contiguous area to be devoted to open space. In addition, this drive will be used only by delivery vehicles and vehicles dropping off or picking up clients. At any time during the day when that activity is not underway, the drive will be closed to all other traffic. Vehicles entering or leaving the staff parking lot will not be allowed to use that drive but will instead be required to use the two lane drive at the NW entry to the site. The highest incidence of traffic will be through the front parking lot for clients and other visitors concentrated in the zone between the building and SW Scoffins Street. This parking area includes pedestrian walkways along the building front and along the street as well as connecting directly from the street to the main entrance of the buildings. All pedestrian and parking area will have outdoor lighting to ensure visibility and safety. Recycling, dumpsters, and other refuse containers will be located near the rear entrance to the building, screened from the main street by the building itself. In addition, this area will be screened from adjacent properties by existing mature vegetation and fencing along the other three property lines. 18.705 ACCESS, EGRESS AND CIRCULATION The main public entrances to the building are oriented to SW Scoffins Street, which already has sidewalks in place for use by pedestrians. A new five foot wide, ADA-compliant concrete pedestrian walkway will make a direct link from the main entrance to the street sidewalk. This walkway will be separated from the parking area through which it crosses by a six inch curb and landscape islands, and by a contrasting texture for the 27 feet that it traverses the actual drive. Entrances to the existing and new buildings are connected to each other and to the parking area by a new ADA-compliant concrete walkway approximately 4'-9" in width. The current parking and vehicular circulation on the site is such that traffic traveling on SW Scoffins Street is occasionally obstructed by vehicles entering or leaving the site or by vehicles stopping to pick-up/drop-off passengers. The proposed project will reconfigure the parking and driveways to provide for more efficient circulation as well as locating passenger pick-up/ drop-off entirely on-site, thereby alleviating problems with blocking traffic on SW Scoffins. Emergency vehicles can access the site via a new paved drive connecting the existing NW entrance and drive with a new entrance to the South. This drive allows any emergency vehicle to circle through the site rather than requiring the vehicle to turn around or back into the street. Likewise, the new entrance combined with two-way drives will allow all vehicles to leave the 4 site in a forward motion. The design of vehicle and pedestrian circulation on the site is intended to promote efficiency and convenience by placing the main entrances to the buildings in close proximity to each other and by clustering the parking spaces near the entrances. In addition, pedestrian safety is enhanced by locating the vehicular circulation at the perimeter of the site, away from the building. Delivery vehicles will have access to the building at the rear ground-floor entrance. 18.745 LANDSCAPING AND SCREENING The design of the project as proposed allows for 18% of the site to remain open space/ landscaping. The new building has been placed in the interior of the site to minimize the removal of existing landscaping while preserving as much contiguous space as possible for landscaping and open space near the outdoor recreation area. The existing mature trees, vegetation, fences and walls located along the interior property lines will remain and will be protected during construction by fabric netting or fencing and bio-filtration bags. During grading and construction, topsoil will be stockpiled and protected with erosion control barriers near the Southernmost corner of the site for later use in the new landscaped areas. New landscaping elements will be of a similar size and species to blend well with the existing vegetation and will be serviced by extending the existing irrigation system as needed. Preliminary selections for new landscaping include laurel hedges, azaleas and sunburst locust trees. Sunburst locust has also been proposed for two new street trees. Please see the Landscape Plan for number, species and location of new and remaining plantings. All interior property lines are currently screened by dense mature vegetation composed of hedges, trees and/ or fences and walls. Per Table 745.1, Buffer Matrix, a "D" buffer is required between a commercial use in the CBD zone and a residential use. The buffers along the NW and SW property lines adjoining the mobile home park is consistent with an Option 2 buffer per Table 745.2, Buffer Combinations, with trees at 18" spacing, shrubbery and a 6' fence. The buffer along the SW property line is fully mature and the one along the NW property line can be expected to reach maturity and full screening within two years or less. Existing vegetation along the SE property line is extremely dense, with large mature trees and a full 6' hedge rendering complete visual opacity on that edge of the site. A portion of the hedge will need to be removed near SW Scoffins Street to allow for adequate visual clearance from the new entry drive. 18.765 OFF-STREET PARKING & LOADING The proposed project will increase the gross floor area of the facility from 8,056 square feet to a total of 20,092 square feet , Per Table 18.765.2, the minimum number of parking spaces required would be 2.7 for every 1000 sq. ft., or fifty-five (55) spaces, in addition to two (2) designated disabled-accessible parking spaces. The site currently has approximately 20 parking spaces, 2 of which are designated as disabled-accessible. TVC is planning to add an additional 17 spaces, bringing the total to 35 standard spaces and 2 disabled-accessible spaces. All of the required spaces can be located on-site well within 200 feet of the buildings. The number of staff is expected to increase from approximately 17 to approximately 30, many of whom carpool, take public transit, or work part-time and/or staggered shifts and are not on- site simultaneously. The client base is also expected to increase, however, the children and adolescents who comprise the client base either arrive by bus, van or private vehicles. Consequently, calculating the necessary number of parking spaces based strictly on square footage in this case would lead to an excessive number of spaces, most of which would 5 remain unused. The proposed project has been designed to allow for additional parking to be added in the future should the need arise through a change of ownership or use. The site layout can accommodate an additional nine (9) parking spaces and still retain the required 15% landscaping. That would bring the total on-site parking to forty-six (46) spaces. Per Section 18.765.030.13, required parking spaces in excess of forty (40) may be located off-site, within 300 feet of the primary site. TVC has an agreement with the property owners of the shopping center to the North to allow TVC staff to park in the auxiliary lot located in the Southeast area of the shopping center property, directly across SW Scoffins Street from the main building entry. This would allow TVC, or any future owner or use, to fully meet the parking requirements of the code. TVC would like to limit the number of parking spaces in order to better meet the intent of the code, i.e. to ensure adequate parking and maintain the traffic carrying-capacity of the street, and to preserve as much area as possible for common open space and landscaping. The design of the project as proposed allows for 18% of the site to remain open space/ landscaping. Sixteen (16) parking spaces for staff have been located along the NW & SW edges of the site with walkways leading into entrances at the side and rear of the building. Vehicles entering or leaving the main staff parking lot will be required to use the two lane drive at the NW entry to the site. Twenty-one (21) parking spaces for overflow staff and visitors are located in the front parking lot between the buildings and SW Scoffins Street. Two (2) disabled-accessible parking spaces are located in the front lot near the main entrances. Both access drives to the front parking area are designed to carry two way traffic. All drives and parking areas will be improved with an asphalt or concrete surface. Delivery vehicles will also have access to the building via the two lane drive from the NW entry. Loading and unloading of goods will occur at the rear ground floor entrance. Clients traveling by van or bus will also disembark at the rear ground floor entrance. Van and bus traffic will arrive at the site via the NE entry drive and travel around the outdoor recreation area to the rear ground floor entrance. Vans and buses will then continue in a forward motion and exit the site at the NW entry. When not in use, the drive around the perimeter of the recreation area will be closed to traffic. The current parking and vehicular circulation on the site is such that traffic traveling on SW Scoffins Street is occasionally obstructed by vehicles entering or leaving the site or by vehicles stopping to pick-up/drop-off passengers. The proposed project will reconfigure the parking and driveways to provide for more efficient circulation as well as locating passenger pick-up/ drop-off entirely on-site, thereby alleviating problems with blocking traffic on SW Scoffins. A bicycle parking area for a minimum of eight (8) bicycles (as required per Subsection 18.765.050) has been located adjacent to the walkway under the canopy (within 10' feet) of the main public entrance to the new building. 18.780 SIGNS The facility currently has a single sign. It is a free-standing structure located on a concrete pad by the property line, just to the north of the existing entry drive and approximately 6 feet from the edge of the SW Scoffins Street sidewalk. The structure is about 1 foot thick and has two faces, each approximately 4 feet wide by 10 feet tall, with painted wood siding, and smaller plastic signs duplicated on both faces announcing the individual programs housed at the Center. Pendant lamps focused on the signage extend approximately 2 feet beyond the 6 structure above each face at the top. However, these lamps are rarely used. As vehicular traffic approaches from the South over the rise of the hill, drivers are not able to see the sign until it is almost too late to safely turn into the drive, often causing them to brake and turn suddenly without proper signaling. This potential hazard could be alleviated by placing an additional sign adjacent to the new entry drive proposed at the opposite end of the street frontage to the site. The new sign structure would be very similar in configuration and appearance to the existing sign but would differ in that it would be somewhat smaller and would not require a foundation or lighting. The new sign will be placed to the north of the new entry drive and out of the public right-of-way to maintain visual clearance for drivers entering or leaving the site. Please see the Site Plan for the location of existing and proposed signs. 18.790 TREE REMOVAL The project has been designed to minimize the removal of existing landscaping while preserving as much contiguous space as possible for landscaping and open space near the outdoor recreation area. All trees and vegetation to be removed are centralized in the interior of the site, in the immediate area of the new building, or in the area of the new parking lot and entry drive. Eight (8) trees of 12" or greater in diameter will be removed. Thirteen (13) trees of 12" or greater in diameter will remain. Four new deciduous trees are planned for the parking area along with two new street trees on that portion of SW Scoffins. It should also be noted that all four of the largest trees (24" �) on the site will remain, as will a number of trees of less than 12"� not listed below. Therefore, while the percentage of trees (in number) removed is more than 25%, the actual net loss of trees (in number) is 9% and the cumulative loss of canopy cover is negligible. Trees with 12"� or greater to be removed: Trees with 12"� or greater to remain: 16"� cherry 12"� pine 16"� cedar 24"� cedar 20"� walnut 14"� spruce 20"� maple 14"� fir 14"� apple 14"� fir 20"� apple 24"� fir 12"� pine 24"� fir 12"� spruce 24"� cedar 14"� cedar 14"� cedar 14"� pine 12"� maple 12"� maple 18.795 VISUAL CLEARANCE AREAS The site is located on the crest of a hill on SW Scoffins Street, a designated Minor Collector with two lanes and a center turning lane. As vehicular traffic approaches from the South over the rise of the hill, drivers are not able to see the sign indicating the entrance to the site until it is almost too late to safely turn into the drive, often causing them to brake and turn suddenly without proper signaling. This potential hazard could be alleviated by placing an additional sign adjacent to the new entry drive proposed at the opposite end of the street frontage to the site. The new sign would be placed adjacent to the new entry drive and out of the public right- of-way to maintain visual clearance for drivers entering or leaving the site. 7 SW Scoffins Street in a non-arterial street approximately 34 feet in width. The new drive will be a minimum of 24 feet in width. The resulting visual clearance triangle will be delineated, per Section 18.795.040.13, from points on the property line 30 feet to each side of the centerline of the drive and a point on the centerline 30 feet back from the property line. Portions of the existing hedge along the SE property line near SW Scoffins will need to be removed to allow for adequate visual clearance to the south of the new entry drive. No new street trees or other landscaping over 3 feet in height will be located in this triangle. 18.810 STREET & UTILITY IMPROVEMENT STANDARDS SW Scoffins Street currently has 5' public sidewalks and 5' planting areas in place along the site frontage. However, the project will require the removal of an existing curb cut (at the driveway for the two story wood frame house) and the introduction of a new curb cut at the location of the new NE entry drive. Consequently, a portion of the sidewalk along that area will be replaced by a new ADA compliant, 5' sidewalk, and a 5' planting area with street trees as required. No new street signs will be required. All public utilities are already available on the site. No new easements will be necessary. The project requires three-phase electrical power for the elevators and sanitary sewer pumps. A three-phase transformer is located directly across SW Scoffins Street from the site. New underground lines will bring power from the existing transformer to a new on-site transformer located in the landscaped zone south of the entrance to the new building. The new transformer will be screened fully from public view by appropriate hedges, fences or other landscaping elements. The owner is still considering options with regard to the relocation of the overhead utility lines serving the site. The sanitary sewer line to the existing building connects to an existing sanitary sewer main located in SW Scoffins Street near the existing NW entry drive. That main represents the end of that sewer line, consequently, the City Engineer has suggested that a new six inch sanitary sewer line connect the new building to the existing main without requiring an additional, intervening manhole. HBH Consulting Engineers has been contracted to design the on-site storm drainage system. Please reference the HBH drawings included with the permit submittal. There are no designated bikeways or pedestrian pathways adjoining the site. The project is designed to have minimum impact, enhanced safety, improved circulation and provide an improved business and service environment for the Tualatin Valley Centers Adolescent Day Treatment Program. 8 TUALATIN VALLEY CENTERS ADOLESCENT DAY TREATMENT PROGRAM MARK LEWIl--TSOHN, DIRECTOR 8770 SW SCOFFINS ST. TIGARD, OR. 97223 (503) 684-1424 LANDSCAPE NARRATIVE JULY 25, 2000 #LUR 99-00322 v JOHN W. FINKLEA, ARCHITECT 3223 SW NAITO PARKWAY PORTLAND, OR. 97201 (503) 248-0617 Tualatin Valley Centers - Scoffins Street - Tigard Landscape Narrative: The current facility occupied by Tualatin Valley Centers is an 8,000 square foot, two story wood frame structure with paved parking areas on the north, east, and west sides of the building. The south side of the building is adjacent to a densely landscaped area which followed a previous lot line demarcation. This landscaping includes an 8'-10' high laurel hedge running the entire length of the site. Directly south of the building are several Rhododendron bushes and a small number of flowering Azaleas. The landscaped areas around the parking areas are similarly planted with small deciduous trees and shrubs. 4� Since much of the existing planting and landscaped areas will remain intact, ti c rip. the intent of the new landscaping will be to blend in with the existing. Street trees and t shrubs will be of the same species and will be spaced with similar distances between ° 3. yyyggiR'r.- trees. The new landscaping areas around the proposed addition will contain shrubs 'SMI and flowering bushes of similar size and species as the areas surrounding the existing building. These plantings will be serviced by extending the existing irrigation system as needed. As construction progresses, the topsoil will be stockpiled in the southwest r comer of the site. The soil will be covered with plastic and surrounded by silt fences to protect from erosion. Since the site and main area of construction slopes away from the street, much erosion will run to the back of the site. Bio-filter bags will be used to protect all existing catch basins both on and off site.

If the trees are fenced, protected and kept from injury, I am confident that all the trees will survive and grow well into the future. I would however point out that the Lawson false cypress could surrcome to phytophthora, which has been a problem for that tree species. A treatment of Subdue granules made annually could be applied to preserve the tree from that fungal pathogen, but phytophthora has little to do with the construction process. Should irrigation or drainage be considered I would like to have some say as to how that is done. Removals are trees that could not be saved because they fall into the footprint of the building or drive. Regarding the trees being saved that are impacted by the construction process I have the following recommendations. • Fence off the north side drip line of trees 5-11 to keep out of the construction area. • Should roots over 2" in diameter be encountered I would like to inspect the root and make the cut on those roots. Trees to save but not directly impacted by the construction process need to be protected from dumping or storage of any construction materials in order to keep the trees as healthy in the long run as possible. -Prepared by:John Buttrell, ISI Certified Arborist.

Project Description: The improvements to this site is to demolish an existing house and driveway and to expand the Tualatin Valley Centers building. The building expansion will double the current roof area and square footage. With the new building there will be an expanded parking area in front of the building and an access road that wraps around to the adjoining lower parking lot. See appendix A for a site plan. Basin Parameters: Existing: Currently the entire site drains into the Fanno Creek via two separate means. After splitting the site into three (3) existing basins E1, E2, and E3, we can look at how the water arrives into Fanno Creek. Basins E1 and E2 are collected on site by sump type catch basins and are piped downstream through the neighboring storm system to Fanno Creek. Basin E 1 is piped into Basin E2 where they are combined before leaving the site. See attached Basin Map Basin-01, Existing Drainage Basins. Basin E3 currently leaves the site via overland flow and enters the neighboring storm system. As it enters the neighboring system it is joined with the drainage from Basins E1 and E2 as it flows into Fanno Creek. The combination of all three basins is shown in the report as Basin E4. Below is a table of the Existing Basin Parameter used in the King County"Hyd" program to determine existing peak flows off the site. These parameters are the Hydrologic Soil group (G), pervious area(P), impervious area(I),Total Area(T), pervious area curve number(CP), and impervious area curve number(Cl). See appendix A for maps of existing basins.

Proposed: After the proposed development occurs the site will be split into five (5) basins, Pl, P2, P3, P4, and P5. Basins P4 and P5 continue to drain off site through the neighboring storm system and remain unchanged except that some of the flow is rerouted, they compose of parts of Basins E1 and E2 respectively. Basin P3 stays unchanged and flows off site into the neighboring storm system as before, it was part of Basin E3. Proposed Basins P 1 and P2 will catch and reroute the runoff via two (2) storm filter catch basins. The water will be filtered and treated for both particulate and phosphorus removal,then piped to an underground detention facility. The detention facility will be sized to allow predeveloped flows off the site for 2, 5, 10, and 25 year storm events. The storm water will then be conveyed to an existing public storm system in the intersection of S.W. Ash and S.W. Scoffins. This existing public line then drains into Fanno Creek where the runoff originally went. Basin P6 is a combination of Basins P3, P4 and P5 which flow offsite via the neighboring storm system as they did before. Basin P7 is a combination of Basins P 1 and P2 that flow offsite into an existing public storm system. Below is a table of the Proposed Basin Parameter used in the King County"Hyd" program to determine proposed flows off the site if there were no detention. The detention facility shall be sized(as noted above) so that the site releases no more runoff than it did prior to any improvements. These parameters are the Hydrologic Soil group (G), pervious area(P), impervious area(I), Total Area(T),pervious area curve number (CP), and impervious area curve number(Q.

Time of Concentration: Per the 1990 King County Surface Water Design Manual,travel time is the time it takes water to travel from one location to another in a watershed. It is a component of the time of concentration,which is the time for runoff to travel from the hydraulically most distant point of the water shed. Time of concentration is computed by summing all the travel times for consecutive components of the drainage conveyance system. However since the length of travel is less than 300 feet for our particular site, the runoff hasn't begun to chanalize. Therefore the time of concentration is calculated as sheet flow, which we use the following kinematics equation given to us by the Surface water design manual on page 3.5.2-6. 0.42(n.,L)o.s T� _ (P)0.5(SO)0.4 where: Tt = Travel Time (min) NS = Manning's roughness coefficient from table 3.5.2c L = Flow Length(ft) P = 24-hr rainfall depth (inches) So = slope of hydraulic grade line (ft/ft) Existing: Basin E1 Basin E2 Basin E3 N1 0.011 0.15 0.15 0.011 L1 150 170 260 60 P 2.5 2.5 2.5 2.5 S1 0.0800 0.0412 0.0423 0.0333 T min 1.09 13.44 17.64 *Basin E4 uses the longest time of concentration of the other three basins. *The two year storm depth is conservatively used for all storms since it produces the longest time of concentration.

Hydrology: Peak flows were determined by using the 1990 King County"HYD"Program. The program uses a SCS Type 1A, 24 hour duration storm event. Rainfall depth's were taken from the Unified Sewerage Agency(USA) Design and Construction Standards for Sanitary and Surface Water Management,Chapter 3 -Page 2. The total depth of rainfall (in tenths of an inch) for storms of 24-Hour duration and 2, 5, 10, 25, 50, and 100 year recurrence are 2.50, 3.10, 3.45, 3.90,4.20, 4.50 inches respectively.

Basins P 1 and P2 are diverted to a nearby public storm system. Water Quantity: With the use of an underground detention pipe, the site will not discharge more runoff into Fanno Creek than it did prior to our proposed improvements. The flow will be controlled by a weir type flow control manhole as shown in appendix A. The detention pipe will be sized to store the excess volume of water created with the proposed impervious area created. The existing portion of the site which drains offsite via the neighboring storm system will remain the same. Currently the entire site flowed through this system(basin E4) which was 0.31 cfs for the two year storm. Because we are not removing the existing storm system(just rerouting some of the water) the flow entering the neighbors system is decreased but not detained. Currently the entire site (basin E4)released 0.31 cfs of runoff into Fanno Creek, after development(basin P6) 0.23 cfs is drained without detention leaving only 0.08 cfs of available drainage. This requires us to only release the 0.08 cfs from basin P7 for the two year storm. 2 year 5 year 10 ear 25 year 100 year Basin E4 0.31 0.43 0.50 0.60 0.73 Basin P6 0.23 0.31 0.35 0.40 0.48 Allowable 0.08 0.12 0.15 0.20 0.25 release See appendix C for King County print outs Storm Measured Allowable Actual Height Storage 2 0.22 0.08 0.08 2.25 560 5 0.29 0.12 0.11 3.05 790 10 j 0.33 0.15 0.15 3.33 860 25 1 0.37 0.20 0.20 3.99 960 From the King county print out we can see that two (2) orifices are needed. The bottom orifice is to be 1 3/8". The top orifice located 2.9' up from the invert elevation is 17/8". There will be an overflow at 4.0' above the invert that will release anything greater than the 25-year storm event. Detention will be accomplished with an underground 48" corrugated metal pipe (aluminized). A detail of the detention facility can be found in appendix A. The orifice structure will be an overflow weir with two orifices as described above. Below are the calculations necessary to find the required length of detention pipe. Area of Pipe = 71 (radius)2 = 3.14 (2.0)2 = 12.57 ft2 Volume required = 960 ft' Length =Volume/Area =960/ 12.57 =771f Water Quality: Water Quality for the site was based on the Unified Sewerage Agency(USA)Design and Construction Standards for Sanitary Sewer and Surface Water Management Chapter 3 — Page 32. The facility is to remove 65 percent of the total phosphorous from the runoff from 100 percent of newly constructed impervious surfaces for the storm water event. The water quality devices are designed for a four(4) hour storm event totaling 0.36 inches of rainfall with an average return of 96 hours. The above requirements are met with a storm filter catch basin unit. See appendix D for drawings and removal efficiencies. Down Stream Analysis: The runoff of the existing storm system located on site(basins E1 and E2) is to remain in place unchanged. After the proposed improvements have taken place the existing storm system will drain proposed basins P4 and P5. As we can see from the Hydrology section of this report the increase of flow in basin P4 is less than the increase in flow in basin P5. Hence, the net proposed flow being release into the existing storm system is less than existing conditions therefore no downstream analysis is needed. Proposed basin P3 remains unchanged from existing conditions therefore no evaluation is needed. It was included in this report for detention purposes only. As described above the proposed detention facility was oversized to detain for the whole site to prevent demolition of existing structures. The remaining two (2)basins (P 1 and P2)that flow offsite into an existing nearby public storm system as released by the detention facility. From the water quantity section of the report we see that the 25-year storm only releases 0.20 cfs. HBH Basin Maps Appendix A i \ y, \'' GRAPHIC SCALE # L i 3 ' S' BUIL IN G 1 Inch= 30 t.

Interpretations of such provisions and their application in specific circumstances shall be made by the Agency and City. Any city operating a Local Program may adopt stricter design specifications within its jurisdiction than the specifications stated in this chapter. The engineer may use various computer models or formulas for its hydrograph analysis but the Agency will verify the design calculations based on "HYD". 3.02 Hydrologic Analysis This section presents the acceptable methods for estimating the quantity and characteristics of surface water runoff, as well as the assumptions and data required as input to the methods. These methods are used to analyze existing and design-proposed drainage systems and facilities. 3.02.1 Design Storm The design storms shall be based on two parameters: • Total rainfall (depth in inches). • Rainfall distribution (dimensionless). The design storm event is specified by return frequency and duration. 3.02.2 Hydrograph Method To obtain a realistic and consistent hydrologic analysis for each development site, all developments shall use the hydrograph analysis method for drainage planning and design unless otherwise approved in advance by the Agency. The "HYD" computer program, developed by King County,Washington in its Surface Water Design Manual,January 1990 uses these methods to generate, add and route hydrographs. The Agency will allow the use of the rational method for analysis of drainage basins of 25 acres or less. Design for SWM Chapter 3-- Page I The physical characteristics of the site and the design storm shall be used to determine the magnitude, volume and duration of the runoff hydrograph. ' 3.02.3 Design Storm Distribution K4 The rainfall distribution to be used within the Agency is the design storm o 24-hour duration based on the standard SCS Type 1A rainfall distribution using the chart on the following page. The total depth of rainfall (in tenths of an inch) ^r for storms of 24-hour duration and 2, 5, 10, 25,50 and 100 year recurrence are ��^^F 2.50, 3.10,3.45, 3.90, 4.20, 4.50 inches respectively. ^Yh 'A' ;as NZ39 L Hk F�7�yJ Y 'V t+ SAM s� • ;'.fie *r Design for SWM re. Chapter 3 --Page 2 i. } 3.10.3 On-site Detention Design Criteria a. When required, stormwater quantity on-site detention facilities shall be designed to capture run-off so the run-off rates from the site after development do not exceed the predevelopment conditions, based upon a 2- through 25-year, 24-hour return storm. b. When required because of an identified downstream deficiency, stormwater quantity on-site detention facilities shall be designed such that the peak run-off rates will not exceed predevelopment rates for the specific range of storms which cause the downstream deficiency. C. Construction of on-site detention shall not be allowed as an option if such a detention facility would have an adverse effect upon receiving waters in the basin or subbasin in the event of flooding, or would increase the likelihood or severity of flooding problems downstream of the site. 3.10.4 Impervious Area Used In Design a. For single family and duplex residential subdivisions,stormwater quantity N detention facilities shall be sized for all impervious areas created by the subdivision, including all residences on individual lots at a rate of 2640 square feet of impervious surface area per dwelling unit. Such facilities shall be constructed as part of the subdivision public improvements. b. For all developments other than single family and duplex,the sizing of stormwater quantity detention facilities shall be based on the impervious area to be created by the development, including structures and all roads and impervious areas. Impervious surfaces shall be determined based upon building permits,construction plans, or other appropriate methods deemed reliable by Agency and/or City. 3.10.5 Detention Pond Design. a. Facility Geometrics 1) Interior side slopes up to the maximum water surface shall be no steeper than 3H:1V (Horizontal:Vertical) unless a fence is provided around the facility. If the interior slope needs to be mowed, the slope shall be 4H:1V. Design for SWM Chapter 3 --Page 23 Ursa e. The vegetation inventory,if required,shall include mapping of vegetation types,percent ground and canopy coverage, and tree inventory including tree locations,approximate heights, types, and trunk diameters measured three feet above the ground. Mitigation plan shall include revegetation landscape plan and technical report presenting existing water quality benefits of vegetated corridor and how plan will replace these benefits upon completion of construction. 3.11.5 Water Quality Facilities a. Purpose New development and other activities which create new impervious surfaces are required to construct or fund permanent water quality facilities to reduce contaminants entering the storm and surface water system. b. On-site Water QualityFacilities Required 1) Except as provided in Subsection 2) below, no person shall cause any change to improved or unimproved real property that will, or is likely to, increase the rate or quantity of run-off or pollution from the site without first obtaining a permit from the Agency and following the conditions of the permit. No permit for construction, or land development, or plat or site plan shall be approved unless the conditions of the plat, plan, or permit approval require the construction or funding of permanent stormwater quality facilities meeting the requirements of this Section. 2) Exempt from this permit requirement are sewer lines,water lines, utilities, or other land development activities that will not directly add impervious surface area or increase the amount of storm water run-off or pollution leaving the site once construction has been completed and the site is either restored to or not altered from its approximate original condition. C. Design Standards 1) The stormwater quality facilities shall be designed to remove 65 percent of the total phosphorous from the runoff from 100 percent of the newly constructed impervious surfaces. Impervious surfaces Design for SWM Chapter 3 -- Page 32 shall include pavement, gravel roads,buildings, public and private roadways, and all other surfaces with similar runoff characteristics. 2) The phosphorous removal efficiency specifies only the design requirements and is not intended as a basis for performance evaluation or compliance determination of the stormwater quality control facility installed or constructed pursuant to this Chapter. 3) If an onsite water quality facility cannot be constructed to treat the runoff from the development's impervious surface,then with Agency or City approval, an on-or off-site water quality facility may be designed to treat runoff from an equivalent area of adjacent untreated impervious surfaces. 4) The stormwater quality facilities shall be designed for a dry weather storm event totaling 0.35 inches of precipitation falling in 4 hours with an average storm return period of 95 hours. 5 The water quality facilities for any single family or duplex subdivision shall be adequately sized for the public improvements of the subdivision and for the future construction of single family or duplex houses on the individual lots at a rate of 2640 square feet of impervious surface per dwelling unit. n tions for meeting this Section may be considered by 6) Other design op g Y the Agency for approval. d. Criteria for Requiring Construction of a Water Quality Facility 1) A water quality facility shall be constructed unless,in the judgment of the Agency or City,any of the following conditions exist: a) The site topography or soils makes it impractical,or ineffective to construct an on-site facility; b) The site is small compared to the development plan,and the loss of area for the on-site facility would preclude the effective development. c) There is a more efficient and effective regional site within the subbasin that was designed to incorporate the Design for SWM Chapter 3 -- Page 33 KING COUNTY, WASHINGTON, SURFACE WATER DESIGN MANUAL i where i T, = time of concentration (min), and m = number of flow segments I Sheet Flow: Sheet flow is flow over plane surfaces. It usually occurs In the headwater of streams. With sheet flow, the friction value (n,) (a modified Manning's effective roughness coefficient that includes the effect of raindrop impact; drag over the plane surface; obstacles such as litter, crop ridges, and rocks; and erosion and transportation of sediment) is used. These n,values are for very shallow flow depths of about 0.1 foot and are only used for travel lengths up to 300 feet. Table 3.5.2.0 gives Manning's n, values for sheet flow for various surface conditions. For sheet flow up to 300 feet, use Manning's kinematic solution to directly compute T,: Sheet flow: Tt = 0.42 (n,L)°'8 (Pz) 0.5 where r T, = travel time (min), n, = sheet flow Manning's effective roughness coefficient (from Table 3.5.2C), r L = flow length (ft), P2 = 2-year, 24-hour rainfall (in), (see Figure 3.5.1C) and S. = slope of hydraulic grade line (land slope, ft/ft) Velocity Equation A commonly used method of computing average velocity of flow, once it has measurable depth, is the following equation: V = k � where: V = velocity (ft/s) k = time of concentration velocity factor (ft/s) so = slope of flow path (ft/ft) "k" is computed for various land' .Dvers and channel characteristics with assumptions made for hydraulic radius using the following rearrangement ci N anning's equation: k = (1.49 (R) 0.657 where • R = an assumed hydraulic radius n = Manning's roughness coefficient for open channel flow (from Table 4.3.78 in Chapter 4) 3.5.2-6 1.``o • � T M_- KING COUNTY, WASHINGTON, SURFACE WATER DESIGN MANUAL r CABLE 3.5.2C "n" AND "k" VALUES USED IN TIME CALCULATIONS FOR HYDROGRAPHS 'rt.'Sheet Flow Equation Manning's Values(For the initial 300 It of travel) n,• Smooth surfaces(concrete,asphalt,gravel,or bare hard packed soil) 0.011 Fallow fields or loose soil surface(no residue) 0.05 Cultivated soil with residue cover(s <-0.20 ft/tt) 0,06 Cultivated soil with residue cover(S> 0.20 ft/ft) 0,17 Short prairie grass and lawns 0.15 Dense grasses 0,24 Bermuda grass 0.41 Range(natural) 0.13 Woods or forest with light underbrush 0.40 Woods or forest with dense underbrush 0.80 I Manning values for sheet flow only,from Overton and Meadows 1976(See TR-55,1988) 'k'Values Used In Travel Time/Time of Concentration Calculations Shallow Concentrated Flow (After the initial 300 R of sheet flow,R - 0.1) k, t.

In the Catch Basin StormFilter,polluted runoff enters the system through a traffic-bearing grate into the primary settling chamber where heavier solids drop to a sump.Lighter solids and dissolved pollutants.are then directed under a baffle into the cartridge chamber where the StormFilter cartridge is housed.During filtration, lighter solids and soluble pollutants are removed and clean water is discharged from the filter into the outlet.During extremely heavy storms,water in the primary settling chamber overflows the bypass weir, preventing the re-suspension of sediments and pollutants trapped in the cartridge chamber.

STORMWATER - MANAGE M NT T H E @4� M I R Lg E R ICARITR IM E The patented StormFilter'"cartridge is the heart of the StormFilter system.Its versatility in allowing the filter media to be selected based on your site needs I and passive siphon function that maximizes filter efficiency and longevity make it the leading stormwater treatment technology available today. The StormFilter cartridges are typically housed in a concrete vault.The vault is composed of three bays:a pretreatment bay,a filter bay,and an outlet bay. Polluted stormwater enters the pretreatment bay where heavy solids and floatables are trapped.The pretreated flows are then directed to the filter bay for full treatment.Flow passes through the filters into an underdrain manifold that discharges fully treated flow to the outlet bay.The outlet bay collects flow from the underdrain manifold for discharge through a single outlet pipe. During a storm,the float system in the center of the filter cartridge helps prime a siphon that draws the polluted stormwater through the filtration media and into a center drainage tube.The siphon mechanism is activated as the vault fills with water and the trapped air is purged from under the filter cartridge hood through the air relief valve.When the water in the cartridge reaches the top of the float, buoyant forces pull the float free and allow the filtered water to drain out into the underdrain manifold for discharge.At this point, the air relief valve closes to create the siphon effect.The siphon increases the flow potential and distribution of pollutants across the filter media,increasing the effectiveness and useful life of the filter cartridge. The siphon effect continues until the stormwater in AIR VENT AIR RELIEF VALVE the vault begins to subside.A standing water SCREW CA' column will remain under the filter cartridge GRANULAR MEDIA FLOAT hood until the water level in the vault ROOD reaches the bottom lip of the hood. OUTER SCREEN CENTER DRAINAGE TUBE As the water in the vault continues to drop,air rushes OPTIONAL PLEATED FABRIC INSERT into the cartridge as the water under the hood is released.The BALL VALVE air bubbles agitate the surface of the filter media,causing much of the FLOOR accumulated sediment to drop to the d FLOW a vault floor.This self-cleaning mechanism �� a also increases the effective life of the filter. as e UNDERDRAIN MANIFOLD 2035 NE Columbia BIVd.

It is the only stormwater treatment system to offer such versatility in removing site-specific pollutants.The StormFilter can be customized for each site by using different filter media to remove sediments, soluble phosphorus, nitrates, soluble metals,and oil &grease.In many cases,a combination of media is recommended to maximize the effectiveness of pollutant removal. PERLITE f .µ Perlite is a naturally-occurring puffed volcanic ash. Its highly porous nature, multicellular " structure, and rough edges make it very effective for removing fine particles. Perlite can be used as a stand-alone media or in conjunction with other media. As a stand alone media, perlite effectively removes suspended solids (TSS) and oil & grease. CSF' LEAF MEDIA Using a feed stock of pure deciduous leaves collected by the City of Portland, Oregon, Stormwater Management composts leaves into a mature stable humus. We then process the finished compost into an organic granular media used to remove TSS, oil & grease, and soluble metals. ZEOLITE Zeolite is a naturally-occurring mineral that has been used in a variety of applications to filter 3 water. Zeolite is used to remove soluble metals, ammonium and some organics. Stormwater Management also uses a modified zeolite (SMZ), which is effective for removing soluble phosphorus and nitrates as well as soluble metals,ammonium and some organics. ° t PLEATED FABRIC INSERTS Stormwater Management's pleated fabric inserts are designed to be used as a stand-alone f� t media or in conjunction with other media for more effective pollutant removal.The pleated fabric insert is used primarily for TSS control.The reusable insert fits inside the standard i 1 cartridge,leaving a space between the inside of the insert and the drainage tube.Granular media can be placed in this space to remove selected soluble pollutants. 2035 NE Columbia Blvd. Portland, OR 97211 (I l 503.240.3393 800.548.4667 ".) 503.240.9553 +3,1 stormwatermgt.com GAC (GRANULATED ACTIVATED CARBON) GAC has been used in the water filtration industry for many years.This media is known for its microporous structure and extensive surface area,which provides high levels of adsorption.Stormwater Management has taken this developed filtration media and applied �v it to the stormwater industry for the removal of oil and grease and organics such as pentachlorophenol (PCP) and TNT. IRON-INFUSED MEDIA Stormwater Management's newest addition to media filtration is the iron-infused media. This open-cell structured media is infused with small bits of iron to remove dissolved phosphate. This media has also been shown to reduce soluble copper and zinc, making it extremely f valuable for sensitive watersheds with nutrient loading problems. JJ MEDIA SELECTION The media for your application needs to be selected with an understanding of the pollutants generated from the site and the sensitivity of the receiving waters.The media selection guide below can be used as a basic guideline to maximize the StormFilter's effectiveness.

The purpose of the StormFilter'"is to remove pollutants.To do its job effectively, n each StormFilter is designed to be maintained at regular intervals. StormFilter maintenance is straightforward, efficient and cost-effective.Filter cartridges are removed,the vault cleaned and inspected and new,recharged cartridges installed. The StormFilter design allows maintenance to be performed in dry conditions,which eliminates the need to remove and dispose of large volumes of contaminated standing water.Maintenance is typically annual, but can depend on the pollutant load characteristics of each site.Maintenance for a typical 8'x16' StormFilter with 30 cartridges takes an average of 2.5 hours.After maintenance is completed,Stormwater Management provides a Certificate of Compliance that verifies maintenance has been performed and the StormFilter continues to meet original design standards.This Certificate is sent to the owner and a copy can be sent to the relevant local stormwater authority on request. Stormwater Management provides detailed Operation& MaintenanceMAJ-�--magi `.

The District should be contacted for information regarding the adequacy of circulation systems, the need for fire hydrants, or other questions related tc fire protection. Storm Sewer Improvements: All proposed development within the City shall be designed such that storm water runoff is conveyer to an approved public drainage system. The applicant will be required to submit a proposed storrr drainage plan for the site, and may be required to prepare a sub=basin drainage analysis to ensure that the proposed system will accommodate runoff from upstream properties when fully developed.

The facilities shall be designed to remove 65 percent of the phosphorus contained in 100 percent of the storm water runoff generated from CITY OF nGABO Pre-MaRcatlon Conference Notes Page 3 of 6 Engineering gepnrtment Section newly created impervious aces. The resolution contains a p, Sion that would allow an applican� to pay a fee in-lieu of constructing an on-site facility provided specific criteria are met. The City wil use discretion in determining whether or not the fee in-lieu will be offered. If the fee is allowed, it wil be based upon the amount of new impervious surfaces created; for every 2,640 square feet, of portion thereof, the fee shall be $210. Preliminary sizing calculations for any proposed water qualit} facility shall be submitted with the development application. It is anticipated that this project wil require: Construction of an on-site water quality facility. ( ) Payment of the fee in-lieu. Other Comments: All proposed sanitary sewer and storm drainage systems shall be designed such that Cit} maintenance vehicles will have unobstructed access to critical manholes in the systems. MaintenancE access roadways may be required if existing or proposed facilities are not otherwise readily accessible. TRAFFIC IMPACT FEES In 1990, Washington County adopted a county-wide Traffic Impact Fee (TIF) ordinance. The Traffic Impact Fee program collects fees from new development based on the development's projectec impact upon the City's transportation system. The applicant shall be required to pay a fee based upor the number of trips which are projected to result from the proposed development. The calculation o the TIF is based on the proposed use of the land, the size of the project, and a general use based feE category. The TIF shall be calculated at the time of building permit issuance. In limitec circumstances, payment of the TIF may be allowed to be deferred until the issuance of an occupancy permit. Deferral of the payment until occupancy is permissible g-aly when the TIF is greater thar $5,000.00. PERMITS Engineering Department Permits: Any work within a public right-of-way in the City of Tigard requires a permit from the Engineerinc Department. There are two types of permits issued by Engineering, as follows: Street Opening Permit (SOP). This permit covers relatively minor work in a public right-of-wad or easement, such as sidewalk and driveway installation or repair, and service connections tc main utility lines. This work may involve open trench work within the street. The permitteE must submit a plan of the proposed work for review and approval. The cost of this type o permit is calculated as 4% of the cost of the work and is payable prior to issuance of the permit CITY OF TI AUD Pre-Application Conference Notes Page 4 of f FnglaaeHag aepartmaat Sectlea In addition, the pen _�e will be required to post a bon, similar financial security for the work. Compliance Agreement (CAP). This permit covers more extensive work such as main utility line extensions, street improvements, etc. In subdivisions, this type of permit also covers all grading and private utility work. Plans prepared by a registered professional engineer must be submitted for review and approval.

At the Tigard Location, 8770 SW Scoffins Street, there are a variety of services provided. Many of the services provided are actually off- site, such as school based,programs,programs where services are provided at the client's home, etc. The primary program based at that site is our Adolescent Day Treatment Program. This program serves about 28 students (ages 12-18). The staff plan and administer a treatment plan of group, individual, family and recreational therapy, community and transitional school involvement and psychiatric medical services in'an academic setting. There are seven staff in this program. The students are brought to the center by school bus, cab or private care. In all cases, they are dropped off and no parking is required for their transportation. The program operates from 8:00 AM to 2:30 PM. The Tigard Location also conducts group therapy in the afternoon and in the evening up to 7:30 PM. This activity begins after the Adolescent Day Treatment Program is finished for the day and most associated staff have left. The addition is approximately 12,000 square feet. A portion of which is a recreation area that will only be occupied by the individuals already on site. The existing Adolescent Day Treatment area will house a one room Headstart program with approximately four staff members with hours similar to the Adolescent Day Treatment Program. The addition will provide for three group therapy rooms for the Adolescent Day., Treatment Program with an addition of approximately four staff members. Additionally, two-group rooms for a Young Children Treatment Program will also be provided. These will serve up to 12 children(7-11)with an additional staff of four(4). Two more administrative staff will be added. The addition will provide counseling offices and small group therapy rooms for the various programs. The program hours for the adolescents and young children will remain the same as well as the transportation means.

The owner has agreed to increase the amount of available parking to fifteen(15) spaces. The total parking provided on site is forty(40) spaces which brings the total to fifty-five (55)spaces. Tualatin Valley Centers functions as a general office facility rather than one for medical office use. The psychiatrist is at that site eight(8)hours/month. The majority of the clients that use the services arrive by bus, cab or private car requiring no parking.

Many of the staff based at the Tigard Lovatien.provide services a vay from the site and do not requirc all day parking. The new addition will not require additional parking commensurate with its size. The function of the facility is not related to a medical office building and will not require the amount of parking normally associated with office use.

Finklea, Architect 3233 SW Naito Parkway Portland, OR 97201 Dear John: Thank you for your letter with information from the Tualatin Valley Centers (SDR2000-00017). Staff agrees that parking spaces should be calculated for this facility based on the General Office category, rather than Medical Office. Site Development Review (SDR) 2000-00017 was approved with conditions based on the Center's original submittal. We requested the information prior to approval being effective. However, future plan submittals, improvements and occupancy, will be judged according to the General Office parking standard. This will render the condition regarding added parking moot.

Dear Jim: Enclosed please find a site plan showing the existing building and new addition to the Tualatin Valley Centers Facility. The City of Tigard building department requires approval from your office with respect to the site and building lighting for the new addition. Please note that it is our understanding the existing (west) half of the site can remain as is and does not require additional fixtures. For the new addition, we will be providing exterior wall mounted fixtures adjacent to each exit door. At the east and south walls of the addition we plan to use fixture "J" mounted above each doorway. Along the north wall of the building we plan to use fixture "K". This fixture adds a partial uplighting feature which will provide more lighting on the main facade. The parking area and access drive will be illuminated with pole mounted metal halide fixtures "H". We have selected these fixtures because they provide ease of maintenance as well as the ability to sharply cut-off the lighting pattern near the adjacent residential area. This should provide you with enough information to approve our lighting plan. If you have any questions or would like to make suggestions, please call me at 503-248-0617.

Dear Ms. Hajduk: Our plans show a 20' wide x 10' deep trash enclosure along the west property line. This design is based on the minimum standards method described in 18.755.040 Methods of Demonstrating Compliance. For a non-residential use the requirement is 4 sq.ft./1 ,000 GFA. These requirements combine for a total minimum required area of (10 sq.ft. + (4 x 20) 90 sq.ft. which is substantially less than the 200 sq.ft. we are proposing. The sanitation vendor (Pride Disposal) has approved the size and location of our proposed trash enclosure. (See the enclosed approval letter). If you have any questions, please call 503-248-0617.

Dear Julia: The following are responses to your site development review conditions of approval: 1. Five copies of the proposed public improvement plan have been submitted to Brian Rager for his review. 2. The engineering department has been provided with information regarding the party responsible for providing financial assurance for the public improvements. 3. Plans and calculations regarding the on-site water quality facility as required by Unified Sewerage Agency have been submitted to Brian Rager. 4. Sheet 1.1 shows the revised landscape plan showing shrubs as required for the buffer zone.

As you know, there is a remaining planning review issue that has not been resolved to the satisfaction of the City of Tigard. This issue is in regards to the quantity of parking that is required onsite by the City of Tigard for a building of this size and occupancy. Our intent is to provide a more open, landscaped site while still meeting the minimum parking requirements. While the 40 parking spaces we have provided onsite meets the requirement of the code, it is important to consider that this is more than the intended use of the facility would need. In addition, providing less impervious area will help reduce the environmental impact caused by increased run-off. For these reasons, we feel that shared parking with the property across Scoffins Street truly meets the needs of the project and the neighborhood. Currently, we have an ongoing agreement with the lessee of the property across Scoffins Street that allows Tualatin Valley Center to park unrestricted in the overflow parking area behind the existing buildings. This agreement has been in place for many years without any complaint or restriction and has served both parties quite well. Recently, at the request of the City of Tigard, this agreement was renewed in written form with signatures from both parties and forwarded to the City of Tigard Planning Department. The requirement by the City of Tigard for a "legal binding agreement" that would document this arrangement may be impossible to obtain for many reasons. The property is being leased on a two year revolving term to Rite-Aid by an owner group based out of state. Because of the lease arrangement, the owner cannot give us any long term access to property that is leased to another party. Rite-Aid has agreed that we can park there unrestricted. SDR2000-00017 (cont.) Page 2 In conversations with the property manager, who represents the owner and is the liaison to the lessee, they feel that if we try to push for a more binding agreement we may undermine our existing position making it quite likely that we could not get a binding agreement for longer than a two year period, if at all. The site is large enough that with a revision of the parking and circulation it can accommodate the required number of parking spaces for the building size as well as provide the landscaping as required by the zoning regulations. i his reconfiguration of the site would mean giving up open spaces and providing parking that the building owner does not need. We have designed.a building site that can accommodate the -required parking if, in the future, this building changes hands and another owner occupies this building. With a modest investment, a new property owner could reconfigure this property and provide the required parking spaces onsite. It is our request that we be approved for the site plan that we have presented to the City of Tigard which gives the property reasonable circulation for the function intended and provides the necessary parking that the facility needs to accommodate its use. We respectfully requestthat you allow us to proceed with this project with the approval of the City of Tigard for the parking that is provided with the current agreement with Rite-Aid and with the understanding that this building, in the future, could accommodate the appropriate parking for another tenant should it become necessary or should the agreements with Rite-Aid become restrictive. This will accomplish what is required by the code to the degree that the project should be allowed to move forward. Also, it will give us a site that has an abundance of landscaped and open area, which is what the client and the community desire. We WIN' have overflow parking if we need it and in the future, if the need arises for a change in use, parking can be accommodated onsite. We will work with the City of Tigard to formulate any stipulations or agreements about future use in order to make this approach work and we welcome your cooperation and assistance in moving this project forward.

Removals are trees that could not be saved because they fall into the footprint of the building or drive.

Dear Mr. Brewersdorff: You have requested a letter confirming that not having the ability to use the lower level parking area of the American Legion Post 158 after 3:30PM on Fridays will not cause parking problems for our staff and/or clients. Many of our programs don't operate on Fridays. Currently, the upstairs portion of our existing building is closed on Fridays. Our Adolescent Day Program (located on the lower level of our current building) does operate 5 days per week, but students leave by 2:30 PM. The other program that will be operating (Headstart) 5 days/week, is a half day program. Both of those programs have parents or buses drop off the students in the morning and pick them up in.the afternoon. They will be finished by 12:30 or 1:00 everyday. T do not believe that the American Legion or Tualatin Valley Centers will have any problems sharing the lower level of the American Legion's parking lot. If you have additional questions, please call me at(503)617-3827. Thanks for your cooperation and understanding in resolving this issue.

The TVC is building a 12,000 square foot expansion to an existing 8,000 square foot building. In regard to the Building Division, there appears to be no one still with the organization who knows of any issues related to the permit issuance or the plan check process for building. Various Building Division permits are still coming in. An electrical permit was taken in on November 19, 2001 . A pre-application conference was held on 4-20-00. A Site Development Review application was submitted for the project on 7-27-00. On 8-23-00, the TVC was sent an incompleteness letter. Among the six items that needed to be addressed were parking, fire hydrants, water quality sizing or detention and location, and a USA service provider concurrence. In relation to parking, plans did not address the code required parking. It was suggested that TVC could apply for a 20% parking adjustment. On 9-6-00, the City received a letter from the project architects indicating that it was not their intent to require reduction of parking because they had an agreement with Rite-Aid across Scoffins Street to use some of that center's parking. On 9-11-00, the City received substantiation that the Rite-Aid parking was not in conflict with TVC hours and the number of stalls available. Page 1 of 2 On 9-12-00, the City sent a letter to Connie Weyrauch regarding outstanding issues including the need to show the location of shared off site parking and a plan to show 40 spaces on the TVC site, as well as, documentation of a recorded shared parking agreement with the shopping center for the additional 15 required spaces. On 10-1-00, the current Building Division fees were established. On 10-11-00, the TVC application was deemed complete by Planning. It included plans for 40 spaces on site and 15 behind Rite-Aid. On 11-22-00, the Site Development Review approval was issued with some 31 conditions. Included were conditions regarding an on-site water quality facility and parking and access. One of the conditions required submittal of a formal binding agreement with the Rite-Aid center to provide the additional parking to meet ordinance standards. On 1-8-01, the City received a letter from the architects justifying the TVC operation as general office space as opposed to medical offices, which TVC was considered in the SDR. The latter would have further increased the TVC parking requirement. On 1-24-01 , the City sent a letter to the TVC agreeing that the required parking should be calculated at the general office standard rather than the medical office standard. On 2-1-01, the TVC building permit application was submitted. The application requested deferral of the traffic impact fee. This will mean that the TIF will be six percent higher since Washington County raised TIF's six percent effective 7-1-01. They were informed at the time that the fee would increase. They paid their park system development at this time. The parks SDC fee went up 5-10-01. Sanitary and storm sewer charges did not increase. On 5-15-01, the City received a letter from the project architect indicating one remaining issue. The letter indicated that Rite-Aid was in a two year lease with the out-of-state owner. Since Rite-Aid could not provide a legally binding parking agreement, the TVC pursued other options. On 8-3-01, the TVC provide a parking agreement with the American Legion Post 158. On 8-6-01, the TVC provided a schedule to show that the shared parking would not overlap the two uses. On 8-6-01, the City released the development for go-ahead. On 10-26-01, the main building permit was issued. In summary, the architects and TVC did struggle with providing the required parking. From the start, they had issues with the requirements, but these were finally worked out with the agreement with the American Legion. Rather than repeat the material, I have attached Brian Rager's memo regarding the Engineering process for your review.

TO: Jim Hendryx ✓ C(v FROM: Bill Monahan VVIA DATE: November 14, 2001 ,A PfN SUBJECT: Tualatin Valley Centers, Child and Adolescent Center Attached is information provided to me by Councilor Ken Scheckla. Ken is a member of the Community Development Block Grant Committee. At a recent meeting of the committee, the representatives of the centers outlined their plans for construction of a new facility on Scoffins in Tigard. Please review the materials. According to the agency representatives, actions by the City of Tigard resulted in greater than budgeted fees for planning and building permits. Councilor Scheckla expressed concern over this. I advised Councilor Scheckla that I was unaware of the situation until November 13. Would you please check with your staff and determine the sequence of events where representatives of the centers held a pre-application conference, discussed details with counter staff, building staff, or planning staff. Please also compare the information provided within the materials and provide me with a memo which provides facts from the city's point of view. I expect that Councilor Scheckla will speak with the staff of Tualatin Valley Centers and advise them that the city could consider a waiver of fee requests. Councilor Scheckla asked me if a request could be filed on behalf of the centers, I advised that one could be filed. I told him that to my knowledge no request had been made. Please provide within your response memo clarification of whether this is true. Please provide me with the memo by Wednesday, November 21, so I can include the information in a memo to council within my newsletter next week. aft I.ADWSILLWEMO&TUAL VALLEY CENTERS.DOC WAShINGTON COUNTY OREGON - ACTION - DATE: November 2, 2001 TO: Policy Advisory Board FROM: Staff, Office of Community Develop ent SUBJECT: Tualatin Valley Centers, Child and Adolescent Center In the Agenda packet sent to you last week, we noted that due to the late receipt of the request for Contingency funds for the above referenced project, we were unable to provide your Board with a complete analysis of the request. In February 2000 your Board approved a $450,000 funding request from the Tualatin Valley Centers for their Child and Adolescent Center. By late Spring the agency had nearly completed its successful fund raising campaign (including sufficient funds to enabled the agency to increase the size of the facility by 2,000 sq. ft.), the architect was preparing the final drawings, and the agency was preparing the final plans for submittal to the City of Tigard's planning and building departments. The agency anticipated start of construction in the Fall of that year and completion within 9 months. Because of the building size and type of construction, the agency had budgeted approximately $100,000 toward architectural and owners representation fees and $28,000 to comply with the City's planning and building requirements and to obtain the necessary permits. In addition, the agency had estimated that it would take approximately 90 to 120 days for the City to review the project and grant final approval. Unfortunately, due to unforeseen circumstances the agency underestimated both the time and cost needed to gain final approval for the project. Soon after the submittal of the plans, it became apparent that an impasse had developed between the City and the agency regarding compliance with several City requirements. The impasse lasted for nearly a year while the agency and the City Office of Community Development 1 1 1 SE Washington Street, MS 7, Hillsboro, OR 97123-4055 phone: (503) 846-8814 • fax: (503)846-2882 Page 2 Policy Advisory Board TVC, Child and Adolescent Center Worked toward-a-satisfactory resolution of several is ' es including parking, water qualii acement of natural gas lines and off sifI ngineen g. These additional p 6laM management requfiements-ad-ded-$25-G-,0 a cost of the project. In addition, the permitting fees totaled $63,000 or $35,000 more than the agency had budgeted. In order to offset these additional costs, the agency has had to transfer some of the funds originally budgeted for construction to these other cost areas. The agency is currently working toward increasing contributions from the community and has secured a line-of-credit from a financial institution in order to meet the building construction costs. However, in order to reduce the need for the line-of- credit, the agency is requesting an additional $100,000 from the Block Grant program to be applied to the cost of construction. The agency has given assurance that it will be able to expend all of the Block Grant funds by April 1, 2002. STAFF RECOMMENDATION: Following review and discussion, your Board favorably consider awarding the Tualatin Valley Centers an additional $100,000 for the construction of the Child and Adolescent Center. S/Con-00/2233 PAB ACTN-TVC AGENDA ORDER WASHINGTON COUNTY OREGON - iNFO - DATE: October 31, 2001 TO: Policy Advisory Board FROM: Staff, Office of Community Develop ent SUBJECT: Tualatin Valley Centers, Child and Adolescent Center Attachment A is a letter just received from the Tualatin Valley Centers requesting an additional $100,000 in Contingency funds for the above project. In January 2000 your Board rated and ranked the above project second on the list for all Public Facility projects for the 2000 — 2003 funding cycle. Although the agency intended to start the project shortly after the start of the contract period July 1, 2000 the agency encountered unforeseen costs and delays associated with obtaining all of the necessary approvals and permits. Due to the recent receipt of this request, staff was not able to prepare a complete analysis before the mail-out date. However, staff will complete its analysis and distribute a written report, with a recommendation, to your Board at your November 8, 2001 meeting. The agency will also have a representative at the meeting to answer any questions, cc: Mary Monnat Connie Dunkle-Weyrauch S/Con-00/2233 PAB-NC Office of community Development i 1 1 I SE Washington Street, MS 7, Hillsboro, OR 97123-4055 phone: (503)846-8814 • fax• (KnZi RdR_7RR`) OCT TU_ALA_TINl_ VALLEY C 1: N T 1:--- R- -S October 31, 2001 Peggy Scheer Program Manager Office of Community Development 111 SE Washington St. Hillsboro, OR 97123 Dear Peggy: Tualatin Valley Centers is very appreciative of your award of$450,000 of Community Development Block Grant funds in support of our Child and Family Center project, which houses our Adolescent Day Tieatment Center and a host of other programs to help severely emotionally disturbed children and youth. With your early funding support to lead the way and demonstrate trust in our stewardship, we have been successful in raising i approximately$1.87 million thus far. We have received major grants from many of the local and regional private foundations, as well as contributions from business and community leaders. Now as we face new challenges, both local and national, we ask your help with Contingency Fund Assistance in the amount of$100,000. This request is urgently needed to pay increased building costs. I have enclosed a report detailing the circumstances leading to the additional costs and the current status of the project. As stated in the report, we,have entered the active construction phase and can assure you that we will completely spend down the entire amount of CDBG funding by April 1, 2002. Our Capital Campaign Committee, chaired by local business leaders Conrad and Barbara Pearson of the Pearson Financial Group, and Dave Hansen, of the West Coast Bank, are actively seeking further contributions from business and individual donors to complete our fundraising. We have every confidence that they will be equal to the task, but recognize that these are challenging times for nonprofit fundraising. Once again, your vote of confidence can make all the difference in positioning these contributions as an investment in a healthy community. Thank you once again for all your support. Throughout our 40 years of service to the community, we have been truly fortunate to have our roots in Washington County, where our compassionate services are recognized and valued. We are excited about going forward together to create a new center to serve the needs of more than 1,200 children and families in our community. Sinc ely, r Mary o at President/CEO ® Administration inted .. ... ('ori.,.X4711 Cis.. i r.:nn vn• October 31, 2001 Subject: Request for contingency and/or Re-programmable Income Funds, Project 2233, TVC's Child and Adolescent Center. Dear Policy Advisory Board, In July 2000, Tualatin Valley Centers received a$450,000 CDBG award to help fund a million dollar-plus expansion of our existing facility located on Scoffins Road near the Tigard downtown area. We expected that we would start construction in the fall of 2000, and the project would be completed by June of 2001. On the one hand, we have faced and overcome a number of challenges, and are happy to report that those associated with major fund raising and the positioning of matching funds have been successful, although not totally finished as of this writing. On the other hand, we also were faced with several issues that were beyond our control. We'll elaborate more as we review some of the changes we were forced to make over the course of the past year. Changes in Initial Project Initially, with the success we had in raising funds for this project, it was determined that we would have sufficient resources to permit us to add back 2,000 square feet of much needed space that we had to cut from the original budget. This increased both the classroom size as well as the recreation area. Funding Obtained to Date: CDBG Funding: $450,000 Meyer Memorial Trust: $400,000 Collins Foundation 100,000 M.J.

The most significant were the difficulties we encountered trying to work through municipal development requirements. The Agency encountered a six month delay while we worked with the city of Tigard to resolve an issue related to 14 parking spaces. This resulted in a $75,000 cost that was neither anticipated nor budgeted. Other costs not anticipated included: City extension of services requirements; water quality requirements (not being able to do them on our site); paying for bas lines underground even though tive aren't doing any lines underground; off-site engineering costs which came in at twice as much as anticipated; as well as road usage fees which were also twice the amount. The total amount of unanticipated cost has escalated to more than $250,000. The additional costs had the effect of nullifying what we thought our fund-raising efforts had seemingly cushioned us with. We certainly do not fault the City of Tigard, but more or less reproach ourselves for not realizing that the true costs associated with very large capital projects become a "reality" only when all the pieces of the development process fall into place. Current Status of Project We have been able to work through all the issues keeping us from starting construction. Groundbreaking took place on October 29`'', 2001. Our contract with Par Construction states that construction will be complete by June 1, 2002. Included is a time-line from the contractor. However, after receiving the lowest bid for the project and re-forecasting our budget, we find that we are still $250,000 off our revised budget. As noted, we approached and have been awarded funding from several trusts and charities. We will continue to submit grants for others we haven't approached yet or believe there may be an opportunity to ask for more funding. Additionally, we are just launching the public phase of our Capital Campaign targeting individuals and local companies. We also have pre-positioned ourselves to take advantage of using a letter of credit with a local financial institution. We would like the opportunity to discuss our situation with your Board and ask you for further assistance from your contingency and/or re-programmable income sources. We are respectfully asking for your consideration and favorable endorsement to award an additional sum of$100,000 to help underwrite the success of this project. We feel such a request makes a lot of sense because we want to avoid using the line of credit so that we do not ultimately find ourselves in a financial position similar to the one that confronted the Community Action Organization a few years ago. We believe injecting additional support now is both prudent and timely. With your assistance, we will certainly commit to completing this project as expeditiously as possible. We would also like to assure you that we will spend down the entire amount of CDBG funding by April 1, 2002.

More specifically the site is 1.09 acres within the City of Tigard at 8770 and 8750 S.W. Scoffins Street In between S.W. Hall Blvd and Pacific Hwy. oom O eS� 900ft Sx Tangelo Gt C'r, Cti �a t sr ' t Tigard N) 217 � ' ,, S'�y TreceSITE 02001 AAapQuest.00m, Inc.;02001 Navigation Technobgias No M Project Description: The improvements to this site is to demolish an existing house and driveway and to expand the Tualatin Valley Centers building. The building expansion will double the current roof area and square footage. With the new building there will be an expanded parking area in front of the building and an access road that wraps around to the adjoining lower parking lot. See appendix A for a site plan. 2 as qM Basin Parameters: Existing: Currently the entire site drains into the Fanno Creek via two separate means. After splitting the site into three(3) existing basins E1, E2, and E3, we can look at how the water arrives into Fanno Creek. Basins E 1 and E2 are collected on site by sump type catch basins, Basin E1 is piped into Basin E2 where they are combined before being piped downstream through the neighboring storm system to Fanno Creek. See attached Basin Map Basin-01, Existing Drainage Basins in appendix A. Basin E3 currently leaves the site via overland flow and enters the same neighboring storm system. As it enters the neighboring system it is joined with the drainage from Basins E I and E2 as it flows into Fanno Creek. The combination of all three basins is shown in the report as Basin E4. This basin was used to find the total runoff from the site in determining detention volumes and release rates. .. Below is a table of the Existing Basin Parameter used in the King County"Hyd"program to determine existing peak flows off the site. These parameters are the Hydrologic Soil group (G), pervious area(P), impervious area(I), Total Area(T), pervious area curve number(CP), and impervious area curve number(CI). See appendix A for maps of existing basins. Table 1.1 �. Basin G P I T CP CI (acres) (acres) (acres) E1 C 0.0258 0.1807 0.2066 79 98 ..

Proposed: After the proposed development occurs the site will be split into five(5)basins, PI, P2, P3, P4, and P5. Basins P4 and P5 continue to drain off site through the neighboring storm system and remain unchanged except that some of the flow is rerouted, they compose of parts of Basins E I and E2 respectively. Basin P3 stays unchanged and flows off site into the neighboring storm system as before, it was part of Basin E3. 3 O. wr Proposed Basins P1 and P2 will catch and reroute the runoff via two (2) storm filter catch basins. The water will be filtered and treated for both particulate and phosphorus removal, then piped to an underground detention facility. The detention facility will be sized to allow predeveloped flows off the site for 2, 5, 10, and 25-year storm events. The storm water will then be conveyed to an existing public storm system in the intersection of S.W. Ash and S.W. Scoffins via a new 12"public storm system. This existing public „. line then connects with the neighboring storm system before draining into Fanno Creek. Basin P6 is a combination of Basins P3, P4 and P5 which flow offsite via the neighboring . storm system as they did before. Basin P7 is a combination of Basins P 1 and P2 that flow offsite into an existing public storm system. .. Below is a table of the Proposed Basin Parameter used in the King County"Hyd" program to determine proposed peak flows off the site if there were no detention. The detention facility shall be sized(as noted above) so that the site releases no more runoff .r than it did prior to any improvements. These parameters are the Hydrologic Soil group (G), pervious area(P), impervious area(I), Total Area(T), pervious area curve number (CP), and impervious area curve number(CI).

It is a component of the time of concentration, which is the time for runoff to travel from the hydraulically most distant point of the water shed. Time of concentration is computed by summing all the travel Ow times for consecutive components of the drainage conveyance system. However since the length of travel is less than 300 feet for our particular site, the runoff hasn't begun to chanalize. Therefore the time of concentration is calculated as sheet flow, which we use the following kinematics equation given to us by the King County Surface water design manual on page 3.5.2-6.

The flow will be controlled by a weir type flow control manhole as shown in appendix A. The detention pipe will be sized to store the excess volume of water created with the proposed impervious area created. The existing portion of the site which drains offsite via the neighboring storm system will remain the same. Currently the entire site flowed through this system(basin E4)which was 0.31 cfs for the two year storm Because we are not removing the existing storm system(just rerouting some of the water)the flow entering the neighbors system is decreased but not detained. Currently the entire site (basin E4)released 0.31 cfs of runoff into Fanno Creek, after development (basin P6) 0.23 cfs is drained without detention leaving only 0.08 cfs of available drainage. This requires us to only release the 0.08 cfs from basin P7 for the two year storm.

The bottom orifice is to be 13/8". The top orifice located 2.9' up from the invert elevation is 1 7/8". There will be an overflow at 4.0' above the invert that will release anything greater than the 25-year storm event. Detention will be accomplished with an underground 48" corrugated metal pipe (aluminized). A detail of the detention facility can be found in appendix A. The orifice structure will be an overflow weir with two orifices as described above. Below are the calculations necessary to find the required length of detention pipe. %W 8 Area of Pipe =Tt (radius)2 = 3.14 (2.0)2 = 12.57 ft2 Volume required =940 ft' Length =Volume/Area = 940/ 12.57 = 75 if .r aw a. a. .. 9 am .r .► Water Quality: Water Quality for the site was based on the Unified Sewerage Agency(USA) Design and 00 Construction Standards for Sanitary Sewer and Surface Water Management Chapter 3 — Page 32. The facility is to remove 65 percent of the total phosphorous from the runoff from 100 percent of newly constructed impervious surfaces for the storm water event. '■' The water quality devices are designed for a four(4) hour storm event totaling 0.36 inches of rainfall with an average return of 96 hours. The above requirements are met with a storm filter catch basin unit. See appendix D for drawings and removal efficiencies. Table 1.8 WQ Basin P6 0.027 Basin P7 0.033 .. .N go AV .. .r 10 .W Down Stream Analysis: The runoff of the existing storm system located on site (basins E 1 and E2) is to remain unchanged. After the proposed improvements have taken place, the existing storm system will continue to drain proposed basins P4 and P5. Conveying the runoff into a public storm system, draining into Fanno creek. As we can see from the Hydrology section of this report the increase of flow in basin P4 is less than the increase in flow in basin P5. Hence, the net proposed flow being release into the existing storm system is less than existing conditions therefore no downstream analysis is needed. Proposed basin P3 remains unchanged from existing conditions therefore no evaluation is needed. The runoff flows overland across lawns onto adjacent properties, eventually connecting with the storm system mentioned above. It was included in this report for detention purposes only. As described above the proposed detention facility was oversized to detain for the whole site to prevent demolition of existing structures. The remaining two (2) basins P1 and P2 are rerouted offsite into an existing nearby public storm system with a 25-year storm releases of 0.20 cfs. The basins runoff currently flowed overland across lawns onto adjacent properties with basin P3, eventually draining into the above mentioned storm system. Once released into the public storm system the runoff then connects up with the existing on-site storm system and continues on until eventually released into Fanno creek. Rerouting the runoff simply increased the time of concentration of the runoff into Fanno creek, which would decrease the peak flow. .. The existing storm system is more than adequate to handle the additional flows we are contributing, however further downstream where the two systems converge there is an existing capacity problem. The city of Tigard is aware of flooding in this area and already has plans for updating the system. .. .n r ow 11 ■w .r .r to .r to .w +rr rr HBH Basin Maps .w .o go go go Appendix A � I i I t r E2 I � , � u GRAPHIC SCALE s � ^ rr E1 t IN FEET) E,xISTINl, BILI 1 I `I G' I inch = 30 ft. v I AREA'S S Fl: TOTAL 8998 PERVIOUS = 11125 E'Xil;T1NIG o BUILDING IMPERVIOUS = 787U = -T-1 Ez. _ I TOTAL 1-17025 PERVIOUS = 7-71,3 --- _ I M P E P 10t,_' - 2 E _ ,SPNA�T 1 I TOTAL = ?115,3 PE `,f"10US = 19746 M ERVIOUS = 17186 1 . ..

Interpretations of such provisions and their application in specific — ` circumstances shall be made by the Agency and City. Any city operating a Local Program may adopt stricter design specifications within its jurisdiction than the specifications stated in this chapter. The engineer may use various computer models or formulas for its hydrograph analysis but the Agency will verify the design calculations based on "HYD". r3.02 Hydrologic Analysis This section presents the acceptable methods for estimating the quantity and characteristics of surface water runoff, as well as the assumptions and data required as input to the methods. These methods are used to analyze existing and design-proposed drainage systems and facilities. 3.02.1 Design Storm The design storms shall be based on two parameters: • Total rainfall (depth in inches). Rainfall distribution(dimensionless). ' The design storm event is specified by return frequency and duration. 3.02.2 Hydrograph Method To obtain a realistic and consistent hydrologic analysis for each development site, all developments shall use the hydrograph analysis method for drainage planning and design unless otherwise approved in advance by the Agency. The "HYD" computer program, developed by King County,Washington in its Surface Water Design Manual,January 1990 uses these methods to generate, add and route hydrographs. The Agency will allow the use of the rational method for analysis of drainage basins of 25 acres or less. Design for SWM IChapter 3 --Page 1 x" The physical characteristics of the site and the design storm Shall be used to P Y determine the magnitude,volume and duration of the runoff hey graph. c 3.02.3 Design Storm Distribution .- The rainfall distribution to be used within the Agency is the design storm o 24-hour duration based on the standard SCS Type 1A rainfall distribution using the chart on the following page. The total depth of rainfall in tenths of an inch) 4 for storms of 24-hour duration and 2, 5, 10, 25, 50 and 100 year recurrence are 3" 2.50, 3.10,3.45, 3.90,4.20,4.50 inches respectively. w t5 a� q a QPM z t a�V01P- f Design for SWM Page 2 Chapter 3 -- rrr 3.10.3 On-site Detention Design Criteria a. When required,stormwater quantity on-site detention facilitkshall be designed to capture run-off so the run-off rates from the site development do not exceed the predevelopment conditions, based upon a 2-through 25-year, 24-hour return storm. b. When required because of an identified downstream deficiency, stormwater quantity on-site detention facilities shall be designed such that the peak run-off rates will not exceed predevelopment rates for the specific range of storms which cause the downstream deficiency. C. Construction of on-site detention shall not be allowed as an option if such a 4 detention facility would have an adverse effect upon receiving waters in the basin or subbasin in the event of flooding, or would increase the likelihood ion or severity of flooding problems downstream of the site. 3.10.4 Impervious Area Used In Design moil a. For single family and duplex residential subdivisions,stormwater quantity detention facilities shall be sized for all impervious areas created by the subdivision, including all residences on individual lots at a rate of 2640 square feet of impervious surface area per dwelling unit. Such facilities ® shall be constructed as part of the subdivision public improvements. b. For all developments other than single family and duplex,the sizing of stormwater quantity detention facilities shall be based on the impervious area to be created by the development, including structures and all roads and impervious areas. Impervious surfaces shall be determined based upon �. building permits,construction plans, or other appropriate methods deemed reliable by Agency and/or City. • 3.10.5 Detention Pond Design. a. Facility Geometrics 1) Interior side slopes up to the maximum water surface shall be no steeper than 3HAV(Horizontal:Vertical)unless a fence is provided +• ' around the facility. If the interior slope needs to be mowed, the slope shall be 411:M Design for SWM Chapter 3 --Page 23 w e. The vegetation inventory,if required, shall include ma�pi of vegetation types,percent ground and canopy coverage,and tree inventory including tree locations, approximate heights, types, and trunk diameters measured three feet above the ground. Mitigation plan shall include revegetation landscape plan and technical report presenting existing water quality benefits of vegetated corridor and how plan will replace these benefits upon completion of construction. 3.11.5 Water Quality Facilities a. Purpose New development and other activities which create new impervious surfaces are required to construct or fund permanent water quality facilities to reduce contaminants entering the storm and surface water system. b. On-site Water Quality Facilities Required 1) Except as provided in Subsection 2) below,no person shall cause any change to improved or unimproved real property that will, or is likely to, increase the rate or quantity of run-off or pollution from - the site without first obtaining a permit from the Agency and _. " following the conditions of the permit. No permit for construction, or land development, or plat or site plan shall be approved unless the conditions of the plat, plan, or permit approval require the construction or funding of permanent stormwater quality facilities meeting the requirements of this Section. 2) Exempt from this permit requirement are sewer lines,water lines, utilities, or other land development activities that will not directly add impervious surface area or increase the amount of storm water run-off or pollution leaving the site once construction has been completed and the site is either restored to or not altered from its approximate original condition. C. Design Standards 1) The stormwater quality facilities shall be designed to remove 65 percent of the total phosphorous from the runoff from 100 percent of the newly constructed impervious surfaces. Impervious surfaces to Design for SWM Chapter 3 -- Page 32 shall include pavement, gravel roadi,buildings,public and private roadways, and all other surfaces with,4milar runoff characteristics. 2) The phosphorous removal efficiency specifies only the design requirements and is not intended as a basis for performance evaluation or compliance determination of the stormwater quality control facility installed or constructed pursuant to this Chapter. 3) If an onsite water quality facility cannot be constructed to treat the runoff from the development's impervious surface,then with Agency or City approval,an on-or off-site water quality facility may be designed to treat runoff from an equivalent area of adjacent untreated impervious surfaces. qM 4) The stormwater quality facilities shall be designed for a dry weather storm event totaling 0.36 inches of precipitation falling in 4 hours with an average storm return period of 96 hours. 5 The wateruali facilities for any single family or duplex q ty subdivision shall be adequately sized for the public improvements of the subdivision and for the future construction of single family or duplex houses on the individual lots at a rate of 2640 square feet of impervious surface per dwelling unit. 6) Other design options for meeting this Section may be considered by the Agency for approval. d. Criteria for Requiring Construction of a Water Quality Facility 1) A water quality facility shall be constructed unless,in the judgment of the Agency or City,any of the following conditions exist: a) The site topography or soils makes it impractical,or ineffective to construct an on-site facility; b) The site is small compared to the development plan,and the loss of area for the on-site facility would preclude the effective development. c) There is a more efficient and effective regional site within the subbasin that was designed to incorporate the Design for SWM Chapter 3 --Page 33 J KING COUNTY, WASHINGTON, SURFACE WATER DESIGN MANUAL �r where T, = time of concentration (min), and f m = number of flow segments Sheet Flow: Sheet flow is flow over plane surfaces. It usually occurs In the headwater of streams. With sheet flow, the friction value (n,) (a modified Manning's effective roughness coefficient that includes the effect of raindrop impact; drag over the plane surface; obstacles such as litter, crop ridges, and rocks; and d erosion and transportation of sediment) is used. These n,values are for very shallow flow depths of about 0.1 foot and are only used for travel lengths up to 300 feet. Table 3.5.2.0 gives Manning's n, values for sheet flow for various surface conditions. i For sheet flow up to 300 feet, use Manning's kinemat-it 56l Bion to directly compute T,: r.

In the Catch Basin StormFilter, polluted runoff enters the system through a traffic-bearing grate into the primary settling chamber where heavier solids drop to a sump. Lighter solids and dissolved pollutants are then directed under a'baffleinto the cartridge chamber where the StormFilter cartridge is housed. During filtration,lighter solids and soluble pollutants are removed,and clean water is discharged from the filter into the outlet.During extremely heavy storms,water in the primary settling chamber overflows the bypass weir, preventing the re-suspension of sediments and poilutantstrapped in the cartridge chamber.

Its versatility in allowing the filter media to be selected based on your site needs and passive siphon function that maximizes filter efficiency and longevity make it the leading stormwater treatment technology available today. The StormFilter cartridges are typically housed in a concrete vault.The vault is composed of three bays:a pretreatment bay,a filter bay,and an outlet bay. Polluted stormwater enters the pretreatment bay where heavy solids and floatables are trapped.The pretreated flows are then directed to the filter bay for full treatment.Flow passes through the filters into an underdrain manifold that discharges fully treated flow to the outlet bay.The outlet bay collects flow wo from the underdrain manifold for discharge through a single outlet pipe. During a storm,the float system in the center of the filter cartridge helps prime a siphon that draws the polluted stormwater through the filtration media and into a center drainage tube.The siphon mechanism is activated as the vault fills with water and the trapped air is purged from under the filter cartridge hood through the air relief valve.When the water in the cartridge reaches the-top of the float, buoyant forces pull wrl the float free and allow the filtered water to drain out into the underdrain manifold for discharge.At this point, the air relief valve closes to create the siphon effect.The siphon increases the flow potential and distribution of pollutants across the filter media,increasing the effectiveness and useful life of the filter cartridge. rrr The siphon effect continues until the stormwater in AIR VENT AIR RELIEF VALVE the vault begins to subside.A standing water SCREW CAP *01 column will remain under the filter cartridge GRANULAR MEDIA FLOAT hood until the water level in the vault HOOD reaches the bottom lip of the hood. OUTER SCREEN CENTER DRAINAGE TUBE As the water in the vault continues to drop,air rushes OPTIONAL PLEATED FABRIC INSERT w into the cartridge as the water under the hood is released.The BALL VALVE air bubbles agitate the surface of dw the filter media,causing much of the FLOOR accumulated sediment to drop to the d ° FLOW arr vault floor.This self-cleaning mechanism d also increases the effective life of the filter.

PERLITE artr , Perlite is a naturally-occurring puffed volcanic ash. Its highly porous nature,multicellular structure,and rough edges make it very effective for removing fine particles. Perlite can be °rr used as a stand-alone media or in conjunction with other media.As a stand alone media, perlite effectively removes suspended solids(TSS)and oil &grease. +r CSF® LEAF MEDIA 4� Using a feed stock of pure deciduous leaves collected by the City of Portland,Oregon, to Stormwater Management composts leaves into a mature stable humus.We then process the finished compost into an organic granular media used to remove TSS, oil &grease, rw and soluble metals. ZEOLITE Zeolite is a naturally-occurring mineral that has been used in a variety of applications to filter water.Zeolite is used to remove soluble metals,ammonium and some organics.Stormwater y,w Management also uses a modified zeolite(SMZ),which is effective for removing soluble phosphorus and nitrates as well as soluble metals, ammonium and some organics. PLEATED FABRIC INSERTS Stormwater Management's pleated fabric inserts are designed to be used as a stand-alone 1 media or in conjunction with other media for more effective pollutant removal.The pleated 1 fabric insert is used primarily for TSS control. The reusable insert fits inside the standard is cartridge, leaving a space between the inside of the insert and the drainage tube.Granular �w media can be placed in this space to remove selected soluble pollutants. r�r orr r 2035 NE Columbia Blvd. Portland, OR 97211 �� 503.240.3393 800.548.4667 0 503.240.9553 stormwatermgt.com rrr 1. err •-- s GAC (GRANULATED ACTIVATED CARBON) GAC has been used in the water filtration industry for many years.This media is known for its microporous structure and extensive surface area,which provides high levels of arr adsorption.Stormwater Management has taken this developed filtration media and applied it to the stormwater industry for the removal of oil and grease and organics such as �r+ pentachlorophenol (PCP)and TNT. IRON-INFUSED MEDIA rr � Stormwater Management's newest addition to media filtration is the iron-infused media.This open-cell structured media is infused with small bits of iron to remove dissolved phosphate. This media has also been shown to reduce soluble copper and zinc,making it extremely valuable for sensitive watersheds with nutrient loading problems.

STORMWATER - MANAGE M NT rrr MAINTENANCEMaintenance is crucial to the ongoing effectiveness of all stormwater - treatment solutions.' Orr NEW Tke purpose of the StormFilterT"is to remove pollutants.To do its job effectively, rrD each StormFilter is designed to be ` maintained at regular intervals. �.w . StormFilter maintenance is straightforward, w efficient and cost-effective.Filter cartridges I allare removed,the vault cleaned and inspected and new,recharged cartridges installed. The StormFilter design allows maintenance ' to be performed in dry conditions,which eliminates the need to remove and dispose of large volumes of contaminated standing water. Maintenance is typically annual,but can depend on the pollutant load characteristics of each site.Maintenance for a typical 8'x16'StormFilter with 30 cartridges takes an average of 2.5 hours.After maintenance is completed,Stormwater Management provides a Certificate of Compliance that verifies maintenance has been performed and the StormFilter continues to meet original design standards.This Certificate is sent to the owner and a copy can be sent to the relevant local stormwater authority on request. Stormwater Management provides detailed Operation&Maintenance �— Guidelines with each system and offers a complete range of eAA.,: maintenance services.The Company offers long-term contracts as well wrr as single maintenance arrangements with a variety of payment options. } :OflfiNf4viAv, ` Stormwater Management can perform the entire maintenance or work } � directly with owners who wish to perform their own maintenance.The .rr , Company,as part of our complete service orientation,tracks each system and notifies the owner regarding maintenance needs.We also work with owners to implement source control measures,thereby improving site stormwater management and lowering overall maintenance costs. _ For jurisdictional authorities,Stormwater Management maintains an extensive database and permanent files for all StormFilter installations. « .rr ow +ar 2035 NE Columbia Blvd. Portland, OR 97211 \� 503.240.3393 800.548.4667 0 503.240.9553 0 stormwatermgt.com SDR2000 -00017 TUALATIN VALLEY CENTER ADDITION 24'-01/S' I' TALL LETTERING F=',4 RK ��' • ` "�` EXISTING MANUF.
