SUMMARY 1. Gary Wells filed the application for Tualatin Valley Fire & Rescue ("TVF&R" or the "applicant"). The applicant requests approval of a conditional use permit to construct and operate an 11,882 square foot fire station at 12585 SW Walnut Street; also known as tax lot 4500 WCTM 2S 104AD(the"site"). The fire station will include an apparatus bay for three fire engines, staff dormitories, locker rooms, kitchen, dining and day room, offices, exercise room and storage. The fire station will also provide a 767 square foot community room that will be available for public use. The applicant will provide off-street parking for station staff, the community room and the adjacent park. The applicant also requests sensitive lands review for construction of stormwater facilities within the Krueger Creek buffer area, an adjustment to reduce the driveway spacing requirements along a collector from 200 feet to 25 feet and a sign permit for a double-faced freestanding sign. Additional basic facts about the site and surrounding land and applicable approval standards are provided in the Staff Report to the Hearings Officer dated December 10, 2007 (the " Staff Report"), incorporated herein by reference. 2. Tigard Hearings Officer Joe Turner(the "hearings officer") conducted a duly noticed public hearing to receive testimony and evidence in the matter. At the public hearing, City staff recommended conditional approval of the application. Representatives of the applicant testified in support of the application. One person testified orally in support of the application. One person testified orally with questions and concerns. Other persons testified in writing. Disputed issues in this case include: a. Whether the proposed development complies with CWS buffer requirements for streams and wetlands; b. Whether the City can require a larger stream buffer to protect water quality and wildlife habitat; and c. Whether the development provides an adequate number of off-street parking spaces. 3. The hearings officer concludes that the applicant sustained the burden of proof for a conditional use permit based on the findings and conclusions included and incorporated herein and subject to conditions at the end of this final order. • B. HEARING AND RECORD 1. The hearings officer held a duly noticed public hearing on December 17, 2007 to receive and consider public testimony in this matter. The record includes a witness list, materials in the casefile as of the close of the record, including materials submitted after the hearing, and an audio record of the hearing. At the beginning of the hearing, the hearings officer made the declaration required by ORS 197.763. The hearings officer disclaimed any ex parte contacts, bias or conflicts of interest. The following is a summary by the hearings officer of selected relevant testimony offered at the hearing. 2. City planner Cheryl Caines summarized the Staff Report. a. She noted that the City received a written comment from Verizon Communications stating that phone service is available to the site. b. The City also received a letter from Sue Beilke, director of the Biodiversity Project of Tigard and vice-president of Friends of Summer Creek. Ms. Beilke argued that the proposed 50-foot stream buffer should be measured from the edge of the wetland associated with the stream, based on CWS regulations. Ms. Beilke further argued that the 50-foot buffer is inadequate to protect water quality and wildlife. The buffer should be increased to a minimum 200 feet. Ms. Caines noted that CWS issued a service provider letter approving the proposed buffer. The City has no authority to require a larger vegetated corridor or otherwise apply CWS's regulations in this proceeding. c. She noted that the applicant submitted a supplemental sight distance analysis dated November 29, 2007. d. In response to Ms. Cameron's testimony, she testified that the stream setback requirements are determined by CWS. The applicant proposed to remove two trees on the site, but all of the trees near the stream will remain. The parking requirements are based on the size of the facility and the meeting room. 3. City engineer Kim McMillan testified that CWS issued a service provider letter accepting the 50-foot buffer proposed by the applicant. The applicant must obtain formal approval from CWS before the City will issue building permits for the fire station. She opined that traffic generated by the proposed facility will be imperceptible to surrounding residents. 4. Planner Frank Angelo and TVF&R Division Chief Gary Wells testified for the applicant. a. Mr. Angelo accepted the findings and conditions in the Staff Report with one exception outlined in his December 17, 2007 letter. He noted that there are no overhead utility lines along the site's Walnut Street frontage. Therefore condition of approval 28 should be deleted. He testified that many fire stations provide community rooms. The 767 square foot community meeting room proposed on this site will accommodate a maximum of roughly 20 CUP2007-00003/SLR2007-00004/VAR2007-00036/SGN2007-00171 Hearings Officer Final Order (TVF&R Walnut Station) Page 2 • • people. The Fire District can control the use of the room. He waived the applicant's right to submit a final written argument. b. Mr. Wells testified that the site is located in an area that is currently underserved by TVF&R. Response times in the area range from ten to twelve minutes, compared to six minute average response times in the remainder of TVF&R's service area. The proposed fire station is expected to reduce response times in the area to six minutes or less, consistent with the remainder of TVF&R's service area. 5. Mark Padgett, president of the Quail Hollows homeowners association testified in support of the application. He argued that the proposed fire station will increase public health, safety and welfare. 6. Donna Cameron questioned whether the facility provides sufficient parking to accommodate the proposed community room and the adjacent park. She questioned whether the facility will be setback away from the stream and associated wetlands. The "swampy areas" extend some distance away from the stream. She questioned whether the applicant will remove trees near the stream. 7. At the end of the hearing, the hearings officer closed the public record and announced his intention to approve the application subject generally to recommended conditions in the Staff Report. C.DISCUSSION 1. The Staff Report identifies the applicable approval criteria for the application and applies them to the record in the case. The hearings officer agrees that the standards identified in the Staff Report are applicable and finds that they are correctly applied to the facts of the case in the Staff Report. Substantial evidence in the record shows that the proposed use does or can comply with the applicable approval criteria for a CUP, and adoption of recommended conditions of approval as amended will ensure final plans are submitted and implemented as approved consistent with those criteria and standards and will prevent, reduce or mitigate potential adverse impacts of the development consistent with the requirements of the TMC. The hearings officer adopts the findings and conclusions in the Staff Report, as modified, as his own. 2. The photographs attached to Mr. Angelo's December 17, 2007 letter demonstrate that there are no overhead utility lines along the site's Walnut Street frontage. Therefore condition of approval should be deleted. 3. Ms. Beilke argued that the stream buffer should be measured from the edge of the wetland, rather than from the stream, based on CWS regulations. However the hearings officer has no authority to construe or apply CWS's regulations. The hearings officer finds that the proposed buffer is sufficient to comply with CWS's regulations based on the CWS service provider letter CWS approved site plan. Exhibit B of the application. There is no substantial evidence to the contrary. If Ms. Beilke disagrees with CWS's determination she can appeal it consistent with CWS's regulations. CUP2007-00003/SLR2007-00004/VAR2007-00036/SGN2007-00171 Hearings Officer Final Order (TVF&R Walnut Station) Page 3 • • a. The hearings officer has no authority to require a larger buffer in this case to protect water quality and wildlife. b. The applicant did not propose a trail within the stream buffer with this application. If a trail is proposed in the future it will be subject to further review at that time. 4. The hearings officer finds that the proposed development complies with the approval criteria for sensitive lands review based on the findings in the Staff Report. There is no substantial evidence to the contrary. 5. The hearings officer finds that the proposed facility provides an adequate number of off-street parking spaces to accommodate the demands of the proposed fire station, including the community meeting room. As discussed in the Staff Report, TMC 18.765 requires a minimum of 31 and a maximum of 45 off-street parking spaces to accommodate the uses proposed on the site. The applicant proposed 39 spaces which meets both minimum and maximum standards. The applicant is not required to provide parking for the park, since park development is not proposed with this application. D. CONCLUSIONS Based on the findings and discussion provided or incorporated in this final order, the hearings officer concludes that the applicant sustained the burden of proof that the proposed conditional use permit does or will comply with the applicable criteria of the Community Development Code, provided development that occurs after this decision complies with applicable local, state, and federal laws and with conditions of approval warranted to ensure such compliance occurs in fact. E. DECISION In recognition of the findings and conclusions contained herein, and incorporating the Staff Report and public testimony and exhibits received in this matter, the hearings officer hereby approves CUP2007-00003 (TVF&R Walnut Station), subject to the following conditions of approval: CONDITIONS OF APPROVAL THE FOLLOWING CONDITIONS SHALL BE SATISFIED PRIOR TO THE ISSUANCE OF SITEBUILDING PERMITS: Submit to the Planning Department (Cheryl Caines, 639-4171, ext. 2437) for review and approval: 1.

Prior to issuance of any Certificates of Occupancy, the Project Arborist will submit a final certification indicating the elements of the Tree Protection Plan were followed and that all remaining trees on the site are healthy, stable, and viable in their modified growing environment. 7.

The specific finding is found on page 26 of 30 of the Staff Report and states: "There are existing overhead utility lines along the.frontage of SW Walnut Street... " The Staff Report then continues to require either undergrounding of the utilities or payment of a fee-in-lieu if approved by the City Engineer. We would like the record to reflect that there are no overhead utility lines located along the site's frontage with SW Walnut Street. The attached photos show the frontage along SW Walnut and, as can be seen, there are no overhead utility lines. Given this fact, the applicant would request that this finding be amended to indicate that the utilities are located underground. As well we would request that condition of approval #28 (page 4 of 30) be removed since it is based on the presence of overhead utility lines. Condition of Approval #28 states: The applicant shall place the existing overhead utility lines along SW Walnut Street underground as a part of this project, or. if approved by the City, they shall pay the fee in-lieu of undergrounding... " Amending the finding and removing this condition will accurately reflect the existing situation along the site's frontage.

Coffey,P.E.,DKS Associates SUBJECT: Tualatin Valley Fire & Rescue Walnut Street Station Supplemental Driveway Sight Distance Information P07059-000 This memorandum provides supplemental information regarding driveway sight distance for the proposed Tualatin Valley Fire&Rescue(TVF&R)Walnut Street Station and Community Center located on the north side of Walnut Street between SW Gaarde Street and SW 121st Avenue in the City of Tigard. The transportation impact analysis for this project(dated July 2007) identified a sight distance issue with the proposed westerly access to the sight. Based on discussions with Kim McMillan of the City of Tigard', it was decided that since Walnut Street was recently improved by Washington County,that using Washington County standards for intersection/driveway sight distance would be appropriate. The Washington County standards for intersection/driveway sight distance are attached. The 85th percentile speed on Walnut Street in the westbound direction is 40 mph2 and is 43 mph in the eastbound direction. Therefore, 400 feet of sight distance is required from the proposed westerly driveway to the east. Based on field measurements taken on November 13, 2007,there is 390 feet of sight distance available from the estimated location of the westerly driveway3 looking to the east as shown in Figure 14. A short(approximately five feet in height) wood fence creates the sight distance obstruction. If a portion of the short fence is removed,then there would be 405 feet of sight distance available which would meet the sight distance requirement. If the fence obstruction is removed,then a shed will create the sight distance obstruction at 405 Telephone discussion between Peter Coffey(DKS Associates)and Kim McMillan of the City of Tigard on November 8,2007. 2 24-hour volume and speed survey conducted April 3,2007. 3 Assumed location for sight distance measurement is 47 feet west of the center line of the existing driveway to the site. 4 The 390 feet of sight distance was measured from the approximate location of the proposed westerly site driveway with a driver's eye located 10 feet from the face of curb and 3.5 feet above the driveway to an object height of 4.25 feet. 1400 SW Fifth Avenue Suite 500 Portland,OR 97201 (503)243-3500 ((503)243-1934 fax • www.dksassociates.com 9 , .. .. . , .. -- ---• b:_--- t4,,:,..,_:...1.i.1,-.,-.,‘,.. _r ,,,,,..,,7,1,-Avs .N.1•;-:!-- —".--- '- 10 7,,-..:,..,:;,..,•r,;i: 1,:i; :I.,,,,i, .

APPLICABLE REVIEW CRITERIA AND FINDINGS A. SPECIFIC CONDITIONAL USE APPROVAL CRITERIA Section 18.330.010.A states that the purpose of this chapter is to provide standards and procedures under which a conditional use may-be permitted, enlarged or altered if the site is appropriate and if other appropriate conditions of approval can be met. There are certain uses which due to the nature of the impacts on surrounding land uses and public facilities require a case-by-case review and analysis. Section 18.330.020.A states that a request for approval for a new conditional use shall be processed as a Type III-HO rocedure, as regulated by Chapter 18.390.050 using approval criteria contained in Section 18.330.030A and subject to other requirements in Chapter 18.330. GENERAL APPROVAL CRITERIA FORA CONDITIONAL USE: SECTION 18.330.030 The site size and dimensions provide adequate area for the needs of the proposed use; The existing site is approximately 142,660 square feet (3.28 acres). The proposed building is 11,882 square feet. The building and associated parking will cover 43,163 square feet (approximately 30%) of the site. This report evaluates the proposal and necessary setbacks,landscaping, etc., and as demonstrated in the application and this report,the site size is adequate for the needs of the proposed use. The impacts of the proposed use of the site can be accommodated considering the size, shape, location,topography,and natural features; The station and associated parking have been designed to fit in the southeast corner of the site, avoiding the sensitive areas. The fire station along with associated parking, will cover approximately 30% of the site. Impacts of the proposed use can to accommodated within the site parameters. All required public facilities have adequate capacity to serve the proposal;and All public facilities including streets and storm sewers have adequate capacity to serve the site as discussed in detail elsewhere in this report. The applicable requirements of the zoning district are met except as modified by this chapter. The proposed site is located within the R-4.5 zoning district. Emergency Service facilities are permitted conditionally. As discussed in this report, the project will meet the applicable requirements of the zoning district. The supplementary requirements set forth in other chapters of this Code including but not limited to Chapter 18.780, Signs, and Chapter 18.360, Site Development Review, if applicable, are met or can be conditioned to be satisfied.

TVF&R WALNUT STATION(CUP2007-00003) PAGE 6 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER The use will comply with the applicable policies of the Comprehensive Plan. The Community Development Code implements the Comprehensive Plan. Compliance with Comprehensive Plan policies are, therefore, assured by satisfaction of the applicable development standards of the development code as addressed within this report. FINDING: Based on the analysis above,the General Approval Criteria for a Conditional Use are satisfied. ADDITIONAL CONDITIONS OF APPROVAL FOR CONDITIONAL USE. Section 18.330.030.B states that the Hearings Authority may impose conditions on the approval of a conditional use, which are found necessary to ensure the use is compatible with other uses in the vicinity, and that the impact of the proposed use on the surrounding uses and public facilities is minimized. These conditions may include,but are not limited to the following: Limiting the hours, days, place and/or manner of operation; The proposed use is a fire station and therefore setting limits on hours or manner of operation is not feasible. Requiring design features which minimize environmental impacts such as noise, vibration, air pollution, glare, odor and/or dust; The proposal will not generate any air pollution, odor, glare, or dust that would be considered out of character for the use. An emergency vehicle signal is proposed to alleviate the need to utilize sirens. Because the siren is used for safety when maneuvering in traffic, no further limitations will be imposed to reduce noise impacts. Requiring additional setback areas, lot area, and/or lot depth or width; The.pro osed fire station meets or exceeds any setback requirements. The minimum lot size for emergency services (p5,000 square feet) is also exceeded since the site is over 142,231 square feet. No additional lot area or setbacks are necessary. Limiting the building height, size or lot coverage, and/or location on the site; The proposal is far below the allowances for lot coverage and building height. Because there are sensitive lands on the site, the building has been located in the southeast corner. Further limitations are not necessary for these standards. This criterion is satisfied. Designating the size, number, location and/or design of vehicle access points; Three vehicle access points are proposed. The fire station needs visitor traffic to be kept separate from the areas accessible to employees. Safety has been reviewed by the applicant's traffic engineer (DKS Associates). The three access points meet the code requirements except access spacing standards along a collector. An adjustment is being approved to allow the proposed spacing. Requiring street right-of-way to be dedicated and street(s) to be improved; A recent project widened and improved SW Walnut Street. Right-of-way at both ends of the site does not meet current standards of 35 feet from centerline. The additional dedication is required as discussed under the Streets and Utility sections of this report. Requiring landscaping, screening, drainage and/or surfacing of parking and loading areas; These items are addressed later in this report. As conditioned, the proposal will meet the prescribed requirements of the Tigard Development Code (TDC). Limiting the number, size, location, height and/or lighting of signs; Only one freestanding sign is proposed. A sign permit application was submitted as part of the proposal. The proposed sign meets the requirements for a non-residential use within a residential zone. TVF&R WALNUT STATION(CUP2007-00003) PAGE 7 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER • • Limiting or setting standards for the location and/or intensity of outdoor lighting; A lighting plan was submitted that shows the location and luminaries of proposed pole and wall-mounted fixtures. One light pole in the employee parking area spills over into the back yards of neighborin properties. Staff suggests the Hearing's Officer ask about the intensity of the light and suggest a shield if necessary. Requiring berms, screening or landscaping and the establishment of standards for their installation and maintenance; The landscape buffer along the western boundary does not meet Code. The applicant has been conditioned to revise the buffer. This criterion is discussed in more detail later in this report. Requiring and designating the size, height, location and/or materials for fences; Wooden fencing is proposed around the trash/recyclables storage area. Shrubbery will further screen the enclosure. This criterion is satisfied. Requiring the protection and preservation of existing trees, soils, vegetation, watercourses, habitat areas and/or drainage areas; The building is located in the southeast corner of the site to minimize impact to the on-site wetlands and Krueger Creek. The original proposal was to trench a storm line to the creek from the proposed water quality/detention facility. To minimize impacts on the creek and wetlands, the applicant has revised the proposal to discharge Le stormwater to flow into the vegetated corridor before draining into Krueger Creek. Two trees are being removed, but the majority of trees on-site are being retained. This standard is met. Requiring the dedication of sufficient open land area for a greenway adjoining and within the floodplain when land form alterations and development are allowed within the 100-year floodplain; and Requiring the construction of a pedestrian/bicycle pathway within the floodplain in accordance with the adopted pedestrian/bicycle pathway plan. There is no floodplain on or adjacent to the site. These criteria are satisfied. ADDITIONAL DEVELOPMENT STANDARDS FOR CONDITIONAL USE TYPES: SECTION 18.330.050 Emergency Services and Basic Utilities: a. Minimum lot size shall be 5,000 square feet; b. Minimum setbacks shall be those in the applicable zone; c. Height limitation shall be in accordance with Chapter 18.730; d. Off-street parking and loading requirement shall be in accordance with Chapter 18.765; and e. Screening shall be in accordance with Chapter 18.745. The site is approximately 3.28 acres. Setbacks, height off-street parking and screening standards have been met and are discussed further in relative sections of this report. FINDING: The additional standards for conditional use types can be satisfied as conditioned below. CONDITION: Prior to final building inspection, the applicant shall install a shield on the light pole adjacent to tax lots 4700 and 4800 or direct light away from neighboring residential uses. TVF&R WALNUT STATION(MI32007-00003) PAGE 8 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER . • B. APPLICABLE DEVELOPMENT CODE STANDARDS SITE DEVELOPMENT REVIEW(18.360) 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 proposal's consistency with these Code Chapters is reviewed in the following sections. 18.360.090 Approval Criteria. The Director shall make a finding with respect to each of the following criteria when approving,approving with conditions,or denying an application: Compliance with all of the applicable requirements of this title including Chapter 18.810, Street and Utility Standards; This will be addressed in the relevant other sections of this report. Relationship to the natural and physical environment: a. Buildings shall be: (1) Located to preserve existing trees, topography and natural drainage where possible based upon existing site conditions; (2) Located in areas not subject to ground slumping or sliding; (3) Located to provide adequate distance between adjoining buildings for adequate light, air circulation,and fire-fighting;and (4) Oriented with consideration for sun and wind. b. Trees shall be preserved to the extent possible.Replacement of trees is subject to the requirements of Chapter 18.790,Tree Removal. The build' is proposed in the SW corner of the site to minimize impacts on Krueger Creek As proposed two trees will be removed. Both are within or near parking areas. Drainage will be preserved or improved throughout the site. Based on the topography,the site drains naturally to the north and-west toward the creek The majority of the proposed grading is to create a water quality/detention pond where the storm water will be collected before being released into the creek There will be no circulation, solar or wind issues since there are no other buildings proposed. Exterior elevations: a.Along the vertical face of single-family attached and multiple-family structures... This is not a single-family or multi-family project. This standard does not apply. Buffering,screening and compatibility between adjoining uses: a. Buffering shall be provided between different types of land uses for example, between single- family and multiple-family residential,and residential and commercial uses,and the following factors shall be considered in determining the adequacy of the type and extent of the buffer... Based on the Buffering Matrix (Table 18.745.1), no buffering or screening is required between the proposed and existing uses, emergency services and the existing single-family residences. The proposed parking area on the east side of the site must be buffered. Setbacks of at feast 66 feet exist between the proposed building and neighboring properties. An 8-9 foot landscape buffer is proposed with an evergreen hedge which does not meet the standard. This is discussed further under the Landscaping and Screeni e ng section of gins report. Privacy and noise:multi-family or group living uses: This is not a multi-family project,therefore this standard is inapplicable. Private outdoor area:multi-family use: This is not a multi-family project,therefore this standard is inapplicable. TVF&R WALNUT STATION(CUP2007-00003) PAGE 9 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER • • Shared outdoor recreation areas:multi-family use: This is not a multi-family project,therefore this standard is inapplicable. Where landfill and/or development is allowed within and adjacent to the 100-year floodplain... This area does not abut or lie within a 100-year floodplain.The nearest floodplain is 2,000 feet to the northeast of the site along Summer Creek. The flood elevation at that point is 166 feet,while the lowest elevation on the subject site is 208. Therefore this standard is inapplicable. Demarcation of public,semi-public and private spaces for crime prevention: a. The structures and site improvements shall be designed so that public areas such as streets or public gathering places, semi-public areas and private outdoor areas are clearly defined to establish persons having a right to be in the space, to provide for crime prevention and to establish i maintenance responsibility;and Visitor parking is located on the west side of the building near the community room entrance. Employee parking is on the east side of the building. No on-site walkways are provided that connect the two areas. Crime prevention and safety: a.Windows shall be located so that areas vulnerable to crime can be surveyed by the occupants; b.Interior laundry and service areas shall be located in a way that they can be observed by others; c.Mail boxes shall be located in lighted areas having vehicular or pedestrian traffic; d. The exterior lighting levels shall be selected and the angles shall be oriented towards areas vulnerable to crime;and e. 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. The applicant states that public safety and crime prevention were considered when designing the fire station. Gear lines of sight and visibility are provided for public areas. Lighting is provided to avoid dark spaces and assure safety and comfort for members of the pubic. A lighting plan was provided with the application. The proposed plan was reviewed by Tigard Police and no objections were given. Public transit: a. Provisions within the plan shall be included for providing for transit if the development proposal is adjacent to or within 500 feet of existing or proposed transit route... The site is not adjacent to a transit route; the Walnut Street route (#45) turns north at 121St Avenue. This intersection is less than half a mile east of the site. This criterion is not applicable. Landscaping: a.All landscaping shall be designed in accordance with the requirements set forth in Chapter 18.745; b. In addition to the open space and recreation area requirements of subsections 5 and 6 above, a minimum of 20 percent of the gross area including parking, loading and service areas shall be landscaped;and c.A minimum of 15 percent of the gross site area shall be landscaped. The development site is approximately 142,231 square feet. The proposed landscaping is approximately 21,986 square feet; therefore 15.5% of the site is being landscaped. This fin-e does not take into consideration all of the pervious open space on the site,only the landscaped areas. This standard is met. Drainage: All drainage plans shall be designed in accordance with the criteria in the adopted 1981 master drainage plan; Drainage will be reviewed under 18.810, Utilities. The proposed storm d nage plan has been designed in accordance with Clean Water Services (CWS) Design and Construction Standards which meet and exceed the requirements of the 1981 master drainage plan. TVF&R WALNUT STATION(CUP2007-00003) PAGE 10 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER • Provision for the disabled: All facilities for the disabled shall be designed in accordance with the requirements set forth in ORS Chapter 447;and The applicant states that the development is being designed in accordance with ADA requirements. Typically ADA requirements are reviewed by the Tigard Building Division. Two accessible parking spaces are proposed as required. All of the provisions and regulations of the underlying zone shall apply unless modified by other sections or this title,e.g.,Planned Developments,Chapter 18.350; or a vanance or adjustment granted under Chapter 18.370. The applicant is requesting an adjustment to the access/egress spacing standards. Criteria for this adjustment are adrressed under the Variances and Adjustments section of this report. FINDING: The review criteria of the site development standards are met. Variances and Adjustments (18.370) Section 18.705.020.C.5 states that in all zoning districts where access and egress drives cannot be readily designed to conform to Code standards within a particular parcel, access with an adjoining property shall be considered. If access in conjunction with another parcel cannot reasonably be achieved, the Director may grant an adjustment to the access requirements of Chapter 18.705 through a Type II procedure, as governed in Section 18.390.030, using the following approval criteria: • It is not possible to share access; • There are no other alternative access points on the street in question or from another street; • The access separation requirements cannot be met; • The request is the minimum adjustment required to provide adequate access; • The approved access or access approved with conditions will result in a safe access; and • The visual clearance requirements of Chapter 18.795 will be met. Due to the site's proximity to existing driveways and streets along Walnut, the applicant cannot meet the spacing standard of 200 feet. The easternmost access will be Located approximately 25 feet from the nearest residential driveway; therefore an adjustment is being requested. The applicant has proposed three access points to Walnut. The spacing of these driveways does not meet the standard. The applicant's traffic engineer states that due to the nature of the proposed uses, three separate driveways are recommended. Emergency vehicles have specific needs and should be kept separate from the visitor vehicles. Adjacent existing access drives are for residential use. Shared access between residential uses and fire trucks/employees is not appropriate. Walnut is the only street access to the site due to the sensitive lands on-site and existing development patterns. The applicant designed the plan to have minimal off-site traffic impacts by making the eastern driveway enter-only for fire trucks and employees. According to the applicant's traffic engineer, traffic volumes at this driveway will be low and spread throughout the day. The middle driveway is signalized and is exit- only for fire trucks. The emergency vehicle traffic signal will eliminate potential vehicle conflicts. The western-most drive will be entry/exit for visitors and employees. Traffic volume for this access is also estimated to be low. A gate is proposed to prevent visitor traffic from accessing the rear of the building and exiting through the employee entrance. Based on information provided by the traffic engineer, the proposed design is not expected to create an unsafe situation along Walnut Street. The request is the minimum necessary. There is currently one access to the site. The proposed site plan will add one new entrance-only access and one exit-only access. Based on the site plan, there are no structures existing or proposed within the vision clearance areas. A neighbor's fence prevents sight-distance to the east. The applicant is conditioned to meet this requirement by the City's Engineering division. FINDING: The proposed uses have unique traffic flow needs. Due to the large number of existing driveways along Walnut, it is not possible to meet the access spacing standards. Shared access or access from another street is not an option. The proposed development has been designed to minimize traffic impacts and will not create a hazardous situation. For these reasons,the adjustment request is approved. TVF&R WALNUT STATION(CUP2007-00003) PAGE 11 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER I • RESIDENTIAL ZONING DISTRICTS(18.510) The R-4.5 zoning district is designed to accommodate detached single-family homes with or without accessory residential units, at a minimum lot size of 7,500 square feet. Duplexes attached single-family residences, and some civic and institutional uses are permitted conditionally. Section 18.520.040 states that Development standards in Residential zoning districts are contained in Table 18.520.2 below: TABLE 18.510.2 DEVELOPMENT STANDARDS IN RESIDENTIAL ZONES STANDARD R-4.5 Proposed Minimum Lot Size[1] 7,500 s.f. 142,231 s.f. Average Minimum Lot Width 50 ft. 467 ft. Maximum Lot Coverage - 43,165 s.f. Minimum Setbacks - Front yard 20 ft. 20 ft. - Side facing street on corner&through lots 15 ft.

N/A private street. Maximum Height 30 ft. 20 ft., 11 in.[2] Minimum Landscape Requirement - 15.5% [1]Minimum lot size is based on residential uses only. The table does not specify a minimum lot size for civic uses. Conditional Use standards require a minimum lot size of 5,000 square feet. [2]The measurement provided by the applicant is to the highest gable(26 ft.,11 in). Based on the Development Code the height is measured to the average height of the highest gable of a pitched roof. That measurement is 20 ft.,11 in. Based on the site plan and supplemental information provided by the applicant,the development standards for the R-4.5 zone are met. The proposed use is conditional within the zone, and additional development standards may apply. These requirements are met as discussed under the Conditional Use section of this decision. FINDING: Based on the information provided in the narrative and on the site plan, the development standards in the R-4.5 zone are satisfied. ACCESS,EGRESS AND CIRCULATION(18.705) No building or other permit shall be issued until scaled plans are presented and approved as pprovided by this chapter that show how access, egress and circulation requirements are to be fulfilled. The applicant shall submit a site plan. Three driveways are proposed for the site. The eastern drive is a one-way access for employees and fire trucks. The western drive is access/egress for visitors and an egress point for employees. Fire trucks will exit the site by a third one-way drive in the center. All vehicular access and egress as required in Sections 18.705.030H and 18.705.030I shall connect directly with a public or pnvate street approved by the City for public use and shall be maintained at the required standards on a continuous basis. All three drives are connected to Walnut Street, a public street. TVF&R WALNUT STATION(CUP2007-00003) PAGE 12 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER • • Joint access: Owners of two or more uses, structures, or parcels of land may agree to utilize jointly the same access and egress when the combined access and egress of both uses, structures, or parcels of land satisfies the combined requirements as designated in this title, provided: Satisfactory legal evidence shall be presented in the form of deeds, easements, leases or contracts to establish the joint use; and copies of the deeds, easements, leases or contracts are placed on permanent file with the City. Joint egress is not proposed for this development. This standard does not apply. Required Walkway Location On-site pedestrian walkways shall comply with the following standards: Walkways shall extend from the ground 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; As shown on the site plan,walkways extend from the ground floor entrances on the east and west sides of the building to an existing sidewalk along Walnut Street. This sidewalk connects the site to surrounding residential uses. Within all attached housing (except two-family dwellings) and multi-family developments, each residential dwelling shall be connected by walkway to the vehicular parking area, and common open space and recreation facilities; This criterion is not applicable to this proposal. 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; There are no required walkways crossing vehicle access driveways or parking lots. This standard does not apply. 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 applicant states that walkways will be paved with concrete and will have sufficient lighting according to the submitted lighting plan. Access Management(Section 18.705.030.H): Section 18.705.030.H.1 states that an access report shall be submitted with all new development proposals which verifies design of driveways and streets are safe by meeting adequate stacking needs, sight distance and deceleration standards as set by ODOT, Washington County, the City and AASHTO. DKS Associates prepared a Transportation Impact Analysis, dated July 2007, for the proposed development. The proposed project would add 9 vehicle trips in the AM peak hour and 16 vehicle tnps in the PM peak hour. "The engineer states that this additional traffic combined with future background traffic growth with the study area would not have a significant operational impact at any of the study intersections during the peak periods analyzed. All study intersections would meet the City's intersection performance standards during each of the peak periods analyzed. TVF&R WALNUT STATION(CUP2007-00003) PAGE 13 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER • • Supplemental Driveway Sight Distance Information, dated November 29, 2007, was also submitted by DKS Associates. The posted speed along this section of Walnut Street is 30 mph. However, the 85th percentile speed on Walnut Street in the westbound direction is 40 mph and is 43 mph in the eastbound direction. Therefore 400 feet of sight distance is required from the proposed westerly driveway to the east. Based on field measurements taken on November 13, 2007, there is 390 feet of sight distance available from the estimated location of the westerly driveway looking east. According to the engineer there is a short wood fence that creates the sight distance obstruction. If a portion of the fence is removed there would be 405 feet of sight distance available which would meet the sight distance requirement. If the fence obstruction is removed then a shed will create the sight distance obstruction at 405 feet. If the driver's eye is moved to eight feet from the curb (instead of the required ten feet from the curb) then there would be 410 feet of sight distance without moving the fence. The available sight distance to the west is approximately 800 feet,thereby meeting the standard. The applicant shall, as recommended by DKS Associates, work with the adjacent.property owner to remove a portion of the wood fence located approximately 55 feet east of the project site to obtain a minimum 400 feet of sight distance from the proposed westerly driveway. Upon completion of the public improvements and prior to the final building inspection, the applicant's engineer shall submit a final sight distance certification for the westerly driveway. Section 18.705.030.H.3 and 4 states that the minimum spacing of driveways and streets along a collector shall be 200 feet. The minimum spacing of driveways and streets along an arterial shall be 600 feet. The minimum spacing of local streets along a local street shall be 125 feet. The project proposes three access/egress points on Walnut Street. The easternmost access point is for emergency vehicles and fire station employees only. The center driveway is for emergency vehicles exiting the site only and would be controlled loy an emergency vehicle traffic signal. The western driveway will provide access and egress for visitors and exit only for fire station employees. Walnut Street is classified as a Collector on the City of Tigard's Transportation Systems Plan. This requires a minimum 200 foot spacing standard. This standard cannot be met and serve the needs of the fire station, therefore the applicant has applied for an adjustment to the spacing standard in accordance with 18.370. FINDING: The access, egress,and circulation standards are met. ENVIRONMENTAL PERFORMANCE STANDARDS- CHAPTER 18.725: Requires that federal and state environmental laws, rules and regulations be applied to development within the City of Tigard. Section 18.725.030 Performance Standards regulates: Noise,visible emissions,vibration and odors. Noise. For the purposes of noise regulation, the provisions of Sections 7.41.130 through 7.40.210 of the Tigard Municipal Code shall apply. Visible Emissions. Within the Commercial zoning districts and the Industrial Park (I-P) zoning district, there shall be no use, operation or activity which results in a stack or other point- source emission, other than an emission from space heating, or the emission of pure uncombmed water (steam) which is visible from a property line. Department of Environmental Quality(DEQ) rules for visible emissions (340-21-015 and 340-28-070) apply. Vibration. No vibration other than that caused by highway vehicles,trains and aircraft is permitted in any given zoning district, which is discernible without mstnlments at the property line of the use concerned. Odors. The emissions of odorous gases or other matter in such quantities as to be readily detectable at any point beyond the property line of the use creating the odors is prohibited. DEQ readily for odors (340-028-090) apply. TVF&R WALNUT STATION(CUP2007-00003) PAGE 14 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER • • Glare and heat. No direct or sky reflected glare, whether from floodlights or from high temperature processes such as combustion or welding, which is visible at the lot line shall be permitted, and; 1) there shall be no emission or transmission of heat or heated air which is discernible at the lot line of the source; and 2) these regulations shall not apply to signs or floodlights in parking areas or construction equipment at the time of construction or excavation work otherwise permitted by this title. Insects and rodents. All materials including wastes shall be stored and all grounds shall be maintained in a manner which will not attract or aid the propagation of insects or rodents or create a health hazard. The applicant states the Environmental Performance Standards will be met. During the neighborhood meeting a neighbor asked about noise from the fire truck sirens. The response was that sirens are used when it is necessary to move traffic out of the way. With an emergency signal on Walnut Street, sirens are not necessary as the truck exits the site. After 10 p.m.TVF&R tries to use their sirens as little as possible and only use lights. Trash will be collected and stored as to not attract rodents and insects. No odors, glare, or visible emissions are anticipated from the use. Therefore,this standard has been met. FINDING: Based on the information provided by the applicant, the use of the property will conform to the above requirements. If for some reason the above standards were in question, and it was subsequently found that the use was out of compliance with any of the above standards the property owner would be subject to code enforcement, court review, possible fines,and revocation of the Conditional Use Permit. LANDSCAPING AND SCREENING- CHAPTER 18.745: All landscaping shall be installed according to accepted planting procedures. The plant material shall be of high grade, and shall meet the size and grading standards of the American Standards for Nurberg Stock (ANSI Z-60, 1-1986, and any other future revisions). Landscaping shall be installed in accordance with the provisions of this title. The accepted planting procedures are the guidelines described in the Tigard Tree Manual. These guidelines follow those set forth by the International Society of Arboriculture (ISA) tree planting guidelines as well as the standards set forth in the American Institute of Architects' Architectural Graphic Standards 10th edition. In the Architectural Graphic Standards there are guidelines for selecting and planting trees .ased on the soil volume and size at maturity. Additionally,there are directions for soil amendments and modifications. Certificates of occupancy shall not be issued unless the landscaping requirements have been met or other arrangements have been made and approved by the City such as the posting of a bond. The applicant is proposing to retain six out of seven trees over 12" D.B.H. This represents 85% retention of trees over 12". Therefore,they are not required to mitigate and/or post a bond per Tigard Municipal Code. However, the applicant is claiming that tree 2 is exactly 12", and therefore not subject to mitigation requirements. The a elicant's tree survey should be accurate to the nearest .1 inches in order to demonstrate that a tree is exactly 12 . If a reassessment is not made,then tree 2 should be subject to mitigation. Finally,even if tree 2 is subject to mitigation,then 6 of 8 (75%) trees will be retained. Therefore,the applicant will not have to mitigate anyway. Existing vegetation on a site shall be protected as much as possible. The developer shall provide methods for the protection of existing vegetation to remain during the construction process. The fplants to be saved shall be noted on the-landscape plans (e.g., areas not to be disturbed can be enced, as in snow fencing which can be placed around the individual trees). The applicant's plan set does not show tree protection for those trees to remain during construction. Please have the applicant prepare a tree protection sheet as part of their plan set. The tree protection sheet should follow the project arbonst's recommendations, and include a signature of approval from the project arborist. Approved methods of protection are outlined under the Tree Removal section of this report. TVF&R WALNUT STATION(CUP2007-00003) PAGE 15 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER • • Street trees: Section 18.745.040 states that all development projects fronting on a public street shall be required to plant street trees in accordance with Section 18.745.040.0 Section 18.745.040.0 required that street trees be spaced between 20 and 40 feet apart depending on the size classification of the tree at matunty(small, medium or large). The site front's on Walnut Street, a public street. Street trees are required. The applicant has proposed to plant Jaquemontii Birch (Betula jaquemontii . While this tree is not on the Tigard street tree list, the Qty Arbonsthas approved it for this project. These trees are considered "medium-sized" and are spaced 30 feet apart. This cntenon has been met. Land Use Buffering and Screening: Buffeting and Screening is required between different types of land uses. Residential uses abut the property on the east and west. Walnut Street is to the south, and Jack Park is to the north. Based on the Buffer Matrix (Table 18.745.1), no buffer is required between residential uses and emergency service uses, but a landscape buffer is required between n--ppa-rking lots and residential uses (combination C). The applicant states that option G1 has been chosen. This combination requires a 10-foot wide landscape buffer with a mix of trees, shrubs and a 4-foot hedge. The proposed trees,Raywood Ash, are medium-sized trees and can be spaced 30 feet apart as proposed. The landscape plan shows a hedge and plantings,but the buffer is only 8-9 feet in width. This does not meet the standard. 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 rovide 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. Parking areas will be screened from neighboring properties along the site's eastern boundary. The applicant has also proposed screening along the parking areas to the west of the fire station. Trees are proposed at a ratio of one tree for every 7 parking spaces. The dimensions of the landscape islands are 8.5 wide and 18.5 long and will be protected from vehicular traffic by a curb. Screenin 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 states that a rooftop A/C unit will be screened from view, but no detail was given of the proposed screening.

Containers will be labeled appropriately, and the area meets Fire Code standards. The applicant states that appropriate gate openings will be provided. The Pride Disposal service provider letter stated concerns on the proposed bi-foid gate design. This may not allow the gates to be secured and Pride recommends 10' gates with cane bolt lock-backs in the open position, as well as closed. Detailed plans submitted to the City show swing gates with drop pins in the open and closed positions. The gate opening is 20 feet. This standard has been met. FINDING: Based on the analysis above, the standards for mixed solid waste and recyclable storage area met. OFF-STREET PARKING AND LOADING(18.765) At the time of the erection of a new structure within any zoning district, off-street vehicle parking will be provided in accordance with Section 18.765.070. A minimum of 3.0 spaces is required for every 1,000 feet of building square footage associated with emergency services. The roposed building is 11,882 square feet,but 767 squire feet is for a community room,and 4,392 square feet is for the fire apparatus bay. The applicant based calculations on the emergency services use for 11,882 square feet. A more accurate calculation would consider both the fire station and community room uses and not include the fire apparatus bay. Excluding the bay,the square footage of the fire station is 6,723 square feet. Based on the standards in Table 18.765.2,the minimum par ng required is 21 and the maximum allowed is 31 (4.5/1,000). Community rooms are not classified in the table. The most similar use is Social/Fraternal Clubs/Lodges. Using this classification the minimum is 10 and the maximum is 14. Combining both uses give a total required minimum of 31 and a maximum of 45. The applicant proposed 39 spaces which meets both minimum and maximum standards.

SENSITIVE LANDS(18.775) The development site includes areas of drainageways and associated wetlands. Development of sites that include these areas requires review through the sensitive lands criteria as described below. The site contains two types of sensitive lands; drainageways and wetlands. The proposal is to collect and treat stormwater before releasing it into the wetland buffer (vegetated corridor). The water will then flow overland into Krueger Creek Only the vegetated corridor around the creek and wetlands is being directly impacted by the development. The vegetated corridor is regulated by CWS and the applicant has received approval for the proposal from CWS. According to the CWS Service Provider Letter the vegetated corridor is in degraded condition. The letter was re-issued after the applicant revised plans that included trenching within the wetlands. Both letters were submitted with the application. TVF&R WALNUT STATION(CUP2007-00003) PAGE 19 OF 30 12/17/07 PUBLIC FEARING STAFF REPORT TO THE HEARINGS OFFICER • • No work is proposed within the drainageway; therefore no sensitive lands permit is necessary. Work within the wetland buffer does require a Type II sensitive lands permit. The applicant has applied for the permit and addressed the relative criteria. The proposed land form alteration or development is neither on wetland in an area designated as significant wetland on the Comprehensive Plan Floodplain and Wetland Map nor is within the vegetative corridor established per "Table 3.1 Vegetative Corridor Widths' and Appendix C: Natural Resources Assessments of the CWS "Design and Construction Standards", for such a wetland; The subject site contains areas designated as significant wetland on the Comprehensive Plan Floodplain and Wet and Map and a vegetative corridor of 50-80 feet from the edge of the wetland. The vegetative corridor for this wetland is a CWS water quality buffer and is not subject to the safe harbor provisions of Goal 5.No work is proposed within the significant wetland. The extent and nature of the proposed land form alteration or development will not create site disturbances to an extent greater than the minimum required for the use; The majority of site work is located outside of the buffer and the applicant has revised previous plans to eliminate any disturbance of the significant wetland. This project does not propose any land form alteration or development within the area designated as a significant wetland. The approved CWS plan shows 286 square feet of mitigation near the southwest corner of the site. Any encroachment or change in on-site or off-site drainage which would adversely impact wetland characteristics have been mitigated; The area within the vegetated corridor that is disturbed to install the stormwater outfall pipe will be restored to existing conditions after the work is completed. Where natural vegetation has been removed due to land form alteration or development, erosion control rovisions of the Surface Water Management program of Washington County must be met and areas not covered by structures or impervious surfaces will be replanted in like or similar species in accordance with Chapter 18.745, Landscaping and screening. As stated above,the area of disturbance will be restored after construction is complete. No tree removal is proposed within the sensitive lands. All other sensitive lands requirements of this chapter have been met; The proposed project also involves drainageways which have been addressed within this staff report and found to meet the applicable criteria. The necessary U.S. Corp of Engineers and State of Oregon Land Board, Division of Sate Lands, and CWS approvals shall be obtained. Only a CWS service provider letter was needed for this proposal. A copy has been rovided with the application. The Department of State Lands was provided a copy of the proposal. Comments received indicate no concerns for the proposed activity. The provisions of Chapter 18.790,Tree Removal shall be met; Two trees are being removed from the site, but these are not within the sensitive lands. The tree removal requirements are met. Physical Limitations and Natural Hazards, Floodplains and Wetlands, Natural Areas, and Parks Recreation and Open Space policies of the Comprehensive Plan have been satisfied. TVF&R WALNUT STATION(QJP2007-00003) PAGE 20 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER • • The proposed development plan addresses these plan policies. The majority of the sensitive area on the property will remain in its natural state. The Comprehensive Plan and Comprehensive Plan Map guides development throughout the City of Tigard and is implemented through the Development Code and Zoning Map. Therefore,this standard is satisfied. FINDING: Based on the analysis above,the sensitive lands criteria are met. SIGNS (18.780): Requires that a permit be issued for any sign that is erected, re-erected, constructed, structurally altered, or relocated within the City Limits. 18.780.130 states that no sign of any character shall be permitted in an R-7, R- 4.5, R-3.5, R-2 or R- 1 zone except for non-residential uses, one illuminated or non-illuminated freestanding sign not exceeding six feet in height and 32 sgluare feet in area per sign face for uses approved under the site development review or conditions use process will be permitted. Wall signs may not exceed five percent of the gross area of the wall face on which the sign is mounted. One, illuminated, freestanding sign is proposed with this application. The area is 16.5 square feet per face (33 square feet total). The sign is illuminated by two ground mounted lights. Placement of the sign is outside the visual clearance areas. FINDING: The criteria for signs have been met. TREE REMOVAL - CHAPTER 18.790: Section 18.790.030 requires that a tree plan for the planting, removal and protection of trees prepared by a certified arborist be provided for a conditional use application. The tree 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, identification of which trees are proposed to be removed, and a protection program defining standards and methods that will be used by the applicant to protect trees during and after construction. As required, the applicant submitted a tree plan conducted by Ray Myer, a certified arborist. However, while the report contains the four required components, the applicant has not transferred the information to their plan set (see comments below under protection program). Plan requirements. The tree plan shall include the following: Identification of the location, size and species of all existing trees including trees designated as significant by the city; The Arborist Report identified the location, size and species of all existing trees, consistent with this standard. Identification of a program to save existing trees or mitigate tree removal over 12 inches in caliper. Mitigation must follow the replacement guidelines of Section 18.790.060D, in accordance with the following standards and shall be exclusive of trees required by other development code provisions for landscaping, streets and parking lots: a. Retention of less than 25% of existing trees over 12 inches in caliper requires a mitigation program in accordance with Section 18.790.060D of no net loss of trees; b. Retention of from 25% to 50% of existing trees over 12 inches in caliper requires that two- thirds of the trees to be removed be mitigated in accordance with Section 18.790.060D; c. Retention of from 50% to 75% of existing trees over 12 inches in caliper requires that 50 percent of the trees to be removed be mitigated in accordance with Section 18:790.060D; d. Retention of 75% or greater of existing trees over 12 inches in caliper requires no mitigation. The applicant is ro posing to retain six out of seven trees over 12" D.B.H. This represents 85% retention of trees over 12 . Therefore, they are not required to mitigate and/or post a bond per Tigard Municipal Code. TVF&R WALNUT STATION(CUP2007-00003) PAGE 21 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER lb However, the applicant is claiming that tree 2 is exactly 12", and therefore not subject to mitigation requirements. The applicant's tree survey should be accurate to the nearest .1 inches in order to demonstrate that a tree is exactly 12". If a reassessment is not made, then tree 2 should be subject to mitigation. Finally, even if tree 2 is subject to mitigation, then 6 of 8 (75%) trees will be retained. Therefore, the applicant will not have to mitigate anyway. Identification of all trees which are proposed to be removed; All of the trees proposed to be removed are identified on the proposed tree plan found within the arborist report. A protection rogram defining standards and methods that will be used by the applicant to protect trees dpuring and after construction. The applicant's plan set does not show tree protection for those trees to remain during construction. The applicant must prepare a tree protection sheet as part of their plan set. The tree protection sheet should follow the project arborist's recommendations, and include a signature of approval from the project arborist. All trees to be preserved that will be in close proximity to construction activities shall be protected with five or six (5' - 6') foot high chain link fences. Please have the applicant demonstrate which trees will be protected with plastic and which will be protected with chain link. Fences are to be mounted on two inch diameter galvanized iron posts, driven into the ground to a depth of at least 2-feet at no more than 10-foot spacing. The applicant shall position fencing as directed by the project arborist to protect the trees to be retained. The applicant shall allow access by the City Arborist for the purpose of monitoring and inspection of the tree protection to verify that the tree protection measures are performing adequately. Failure to follow the plan, or maintain tree protection fencing in the designated locations shall be grounds for immediate suspension of work on the site until remediation measures and/or civil citations can be processed. Any tree that is located on property adjacent to the construction project that will have more than 15% of its root system disturbed by construction activities shall also be sown on the plans, and adequately protected. Section 18.790.040 states that any tree preserved or retained in accordance with this section may thereafter be removed only for the reasons set out in a tree plan in accordance with Section 18.790.030, or as a condition of approval for a conditional use, and shall not be subject to removal under any other section of this thapter. The property owner shall record a deed restriction as a condition of approval of any development permit affected by this section to the effect that such tree may be removed only if the tree dies or is hazardous according to a certified arborist. The deed restriction may be removed or will be considered invalid if a tree preserved in accordance with this section should either die or be removed as a hazardous tree. The form of this deed restriction shall be subject to approval by the Director. A condition of approval will ensure that this standard is met. FINDING: Based on the analysis above the Tree Removal standards will be met, if the applicant complies with the conditions fisted below: CONDITIONS: • Prior to commencing site work,the applicant shall submit construction drawings to both Planning and Engineering that include: A.

STREET AND UTILITY IMPROVEMENTS STANDARDS CHAPTER- 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 an arterial street to have a 64 to 128-foot right-of-way width and varied 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 Walnut Street, which is classified as a Collector on the City of Tigard Transportation Ilan Map. At present, there is approximately 35 feet of ROW from centerline along most of the frontage, according to the most recent tax assessor's map. The applicant should dedicate the additional ROW to provide 35 feet from centerline at the east and west ends of the property frontage. SW Walnut Street is currently improved to approximately 22 feet from centerline with a 5 foot planter strip and 6 foot sidewalk. Street Alignment and Connections: Section 18.810.030.H.1 states that full street connections with spacing of no more than 530 feet between connections is required except where prevented by bamers such as topography, railroads, freeways, pre-existing developments, lease provisions, easements covenants or other restrictions existing pnor to May 1, 1995 which preclude street connections. A full street connection may also be exempted due to a regulated water feature if regulations would not permit construction. Section 18.810.030.H.2 states that all local, neighborhood routes and collector streets which abut a development site shall be extended within the site to provide through circulation when not precluded by environmental or topographical constraints, existing development patterns or strict adherence to other standards in this code. A street connection or extension is precluded when it is not possible to redesign, or reconfigure the street pattern to provide required extensions. Land is considered topographically constrained if the slope is greater than 15%for a distance of 250 feet or more. In the case of environmental or topographical constraints,the mere presence of a constraint is not sufficient to show that a street connection is not possible. The applicant must show why the constraint precludes some reasonable street connection. TVF&R WALNUT STATION(CUP2007-00003) PAGE 24 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER • There are no opportunities for street connections through this development due to streams and City park lands. Block Designs - Section 18.810.040.A states that the length, width and shape of blocks shall be designed with due regard to providing adequate building sites for the use contemplated consideration of needs }or convenient access, circulation, control and safety of street traffic and recognition of limitations and opportunities of topography. Block Sizes: Section 18.810.040.B.1 states that the perimeter of blocks formed by streets shall not exceed 1,800 feet measured along the right-of-way line except: • Where street location is precluded by natural topography, wetlands or other bodies of water or,pre-existing development or, • For blocks adjacent to arterial streets,limited access highways,major collectors or railroads. • For non-residential blocks in which internal public circulation provides equivalent access. Section 18.810.040.B.2 also states that bicycle and pedestrian connections on public easements or right-of-ways shall be provided when full street connection is not possible. Spacing between connections shall be no more than 330 feet, except where precluded by environmental or topographical constraints, existing development patterns, or strict adherence to other standards in the code. No new blocks or streets are being proposed with this development. A pedestrian connection across Krueger Creek will be proposed,if possible,with future expansion of Jack Park to the north. 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. Private streets and industrial streets shall have sidewalks on at least one side. There is an existing sidewalk along Walnut Street,thereby meeting this criterion. 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 Clean Water Services in 1996 and including any future revisions or amendments) and the adopted policies of the comprehensive plan. Over-sizing: Section 18.S10.090.0 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 sewer line in SW Walnut Street. The applicant's plans indicate they will install one sanitary sewer lateral to serve the development. Storm Drainage: General Provisions: Section 18.810.100.A 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 Clean Water Services in 2000 and including any future revisions or amendments). The site is adjacent to Krueger Creek,which accommodates upstream drainage. TVF&R WALNUT STATION(CUP2007-00003) PAGE 25 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER • • 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 Clean Water Services in 2000 and including any future revisions or amendments). In 1997, Clean Water Services (CWS) 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 djacent to Fanno Creek. For those developments adjacent to Fanno Creek, the storm water runoff will be permitted to discharge without detention. The applicant's plans indicate they will construct an on-site detention pond upstream of Krueger Creek. The site stormwater runoff will be collected, detained in the pond and then released into the wetland buffer before flowing overland into Krueger Creek. Bikeways and Pedestrian Pathways: Bikeway Extension: Section 18.810.110.A states that developments adjjoining 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. SW Walnut Street is a designated bicycle facility. The bicycle striping and markings are already in place. The applicant shall replace all striping and markings removed or damaged during construction of the three driveways. 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.case-by-case 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-llocated 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 the frontage of SW Walnut Street. If the fee in-lieu is approved by the City Engineer, it is equal to $35.00 per lineal foot of street frontage that contains the overhead lines. The frontage along this site is 465 lineal feet;therefore the fee would be $16,275.00. TVF&R WALNUT STATION(CUP2007-00003) PAGE 26 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER • ADDITIONAL CITY AND/OR AGENCY CONCERNS WITH STREET AND UTILITY IMPROVEMENT STANDARDS: Traffic Study Findings: DKS Associates prepared a Transportation Impact Analysis, dated July 2007, for the proposed development. The proposed project would add 9 vehicle trips in the AM peak hour and 16 vehicle taps in the PM peak hour. The engineer states that this additional traffic combined with future background traffic growth with the study area would not have a significant operational impact at any of the study intersections during the eak periods analyzed. All study intersections would meet the City's intersection performance standards during each of the peak periods analyzed. The engineer identified several transportation mitigations for the proposed project. Based on the operations analysis conducted for the proposed project, no off-site deficiencies were identified. Project related on-site mitigation measures include: 1) an emergency vehicle traffic signal is recommended at the proposed central driveway on SW Walnut Street; 2) relocate the west access approximately 10 feet to the west to align with the residential driveway across SW Walnut Street to reduce potential conflicts between vehicles turning left into these driveways; and 3) there are significant speeding issues on Walnut Street, with the 85th percentile speed at more than 10 miles an hour higher than the posted speed. Traffic calming methods such as increased speed limit enforcement should be implemented to reduce vehicle speeds and potential safety issues. The applicant shall install an emergency.vehicle traffic signal at the central driveway on SW Walnut Street. The signal shall be operational prior to final building inspection. The applicant shall revise the construction plans to relocate the west access approximately 10 feet to the west to align with the residential driveway across SW Walnut Street. Fire and Life Safety: Tualatin Valley Fire and Rescue submitted comments on November 20, 2007. The fire district will do the worksheet and calculate the required fire flow. The fire hydrant on the northwest corner of the SW Walnut Street and SW 124th Avenue meets the hydrant distance requirement. Three fire hydrants are required for this project. The fire hydrant shown on the submitted drawings across SW Walnut Street from the subject property does not contribute to the required number of fire hydrants because SW Walnut is a collector. An additional fire hydrant must be installed on the north side of SW Walnut Street and the east side of the west access drive to accommodate the fire department connection. With the installation of this fire hydrant,the required number of fire hydrants will be satisfied. The applicant shall meet these conditions as outlined in the November 2007 memo and revise the construction plans accordingly. Public Water System: The City of Tigard provides service in this area. There is an existing public water main located in SW Walnut Street. The applicant's plans show two water line taps. These water lines do not require easements within the public ROW. The applicant's plans shall be revised to accommodate the comments received from TVF&R regarding fire hydrants. Storm Water Quality: The City has agreed to enforce Surface Water Management (SWM) regulations established by Clean Water Services (CWS) 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. TVF&R WALNUT STATION(CUP2007-00003) PAGE 27 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER • a Prior to construction, the applicant shall submit plans and calculations for a water quality facility that will meet the intent of the CWS 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. To ensure compliance with Clean Water Services 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: CWS 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 CWS regulations, the applicant is required to submit an erosion control plan for City review and approval prior to issuance of City permits. The Federal Clean Water Act requires that a National Pollutant Discharge Elimination System (NPDES) erosion control permit be issued for any development that will disturb one or more acre of land. This permit will be issued along with the site and/or building permit. Address Assignments: The City of Tigard is responsible for assigning addresses for parcels within the City of Tigard and within the Urban Service Boundary (USB). An addressing fee in the amount of $50.00 per address shall be assessed. This fee shall be paid to the City prior to issuance of the Site Permit. For multi-tenant buildings, one address number is assigned to the building and then all tenant spaces are given suite numbers. The City is responsible for assigning the main address and suite numbers. This information is needed so that building permits for tenant improvements can be adequately tracked in the City's permit tracking system. Based upon information provided by the applicant this building will be a multi-tenant building. Prior to issuance of the site permit the applicant shah rovide a suite layout map so suite numbers can be assigned. The addressing fee will then be calculated-based upon the number of suites that must be addressed. In multi-level structures, ground level suites shall have numbers preceded by a "1",second level suites shall have numbers preceded by a"2",etc. D. IMPACT STUDY(18.390): Section 18.390.040.B.2.e 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 standards, 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. The applicant has submitted an impact study addressing the required elements above. The report substantiates that all services are capable of serving the site. The applicant has submitted an impact study_addressing the required elements above. The report substantiates that all services are capable of serving the site. Storm water collected from the site will be directed to a water quality/detention facility before being released into the wetland buffer. There will be no impact on the public storm system. Water and sanitary is rovided by connecting to a existing lines in Walnut Street. Because the project is not residential,parks will not be impacted. TVF&R WALNUT STATION(CUP2007-00003) PAGE 28 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER • • ROUGH PROPORTIONALITY ANALYSIS 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. Based on the use and the number of new parking spaces proposed, the applicant is required to pay TIF's of approximately$5,201.00. This estimate is based solely on peak hour vehicle trips. Final TIF payment will be assessed at time of building permit submittal. 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 $16,253 ($5,201 divided by .32).. The difference between the TIF paid, and the full impact, is considered the unmitigated impact on the street system. Walnut was recently improved through a City/County project, so no improvements are required at this time. An additional 5 feet of right-of-way must be dedicated at both ends of the site to be 35 feet from centerline;the total is approximately 50 feet. The estimated value is $3.00 a square foot with a total value of $150.00. The unmitigated impact from the proposed development is $10,902 (16,253 - $5,201 - $150). The dedication is required to meet the current minimum standards and is roughly proportionate to the impact of the proposal. SECTION VII. OTHER STAFF COMMENTS The City of Tigard Building Division has reviewed the proposal and commented about the private storm, sanitary service, water service, and grease traps. These issues will be reviewed by the Building Division during permit reviews. The City of Tigard Engineering Department was sent this proposal for review and the comments have been incorporated into this report. City of Tigard Police Department has reviewed this application and has no objections. Tigard Public Works commented that hydrants and meters are to be located within landscaped areas. If the existing service is relocated,then the developer will be billed for the cost. SECTION VIII. AGENCY COMMENTS Tualatin Valley Fire and Rescue (TVF&R) has reviewed the proposal and offered the following comments: Tualatin Valley Fire &Rescue endorses this proposal predicated on the following criteria and conditions of approval: 1) COMMERCIAL BUILDINGS - REQUIRED FIRE FLOW: The required fire flow for the building shall not exceed 3,000 gallons per minute (GPM) or the available GPM in the water delivery system at 20 whichever is less as calculated using IFC,, Appendix B. A worksheet for calculating the required fire flow is available from the Fire Marshal's Office. (IFC B105.2) The fire district will do the worksheet and calculate the required fire flow. 2) FIRE HYDRANTS - COMMERCIAL BUILDINGS: Where a portion of the building is more than 400 feet from a hydrant on a fire apparatus access road, as measured in an approved route around the exterior of the building, on-site fire hydrants and mains shall be provided. This distance may be increased to 600 feet for buildings equipped throughout with an approved automatic sprinkler system. (IFC 508.5.1) The fire hydrant on the northwest corner of SW Walnut Street and SW 124th Avenue meets this distance requirement. TVF&R WALNUT STATION(CUP2007-00003) PAGE 29 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER • • 3) FIRE HYDRANT NUMBER AND DISTRIBUTION: The minimum number and distribution of fire hydrants available to a building shall not be less than that listed in Appendix C Table C 105.1. Considerations for placing fire hydrants may be as follows: • Existing hydrants in the area may be used to meet the required number of hydrants as approved. Hydrants that are up to 600 feet away from the nearest point of a subject building that is protected with fire sprinklers may contribute to the required number of hydrants. • Hydrants that are separated from the subject building by railroad tracks shall not contribute to the required number of hydrants unless approved by the fire code official. • Hydrants that are separated from the subject building by divided highways or freeways shall not contribute to the required number of hydrants. Heavily traveled collector streets only as approved by the fire code official. • Hydrants that are accessible only by a bridge shall be acceptable to contribute to the required number of hydrants only if approved by the fire code official. Three fire hydrants are required for this project. The fire hydrant shown on the submitted drawings across SW Walnut Street from the subject property does not contribute to the required number of fire hydrants because SW Walnut Street is a major collector. FIRE HYDRANT/FIRE DEPARTMENT CONNECTION: A fire hydrant shall be located within 100 feet of a fire department connection (FDC). Fire hydrants and FDC's shall be located on the same side of the fire apparatus access roadway. FDC's s call normally be remote except when approved by the fire code official. (IFC 912.2) An additional fire hydrant must be installed on the north side of SW Walnut Street and the east side of the west access drive to accommodate the fire department connection. With the installation of this fire hydrant, the required number of fire hydrants will be satisfied. 4) ACCESS AND FIRE FIGHTING WATER SUPPLY DURING CONSTRUCTION: Approved fire apparatus access roadways and fire fighting water supplies shall be installed and operational prior to any combustible construction or storage of combustible materials on the site. (IFC 110.1 &1{12.1) Department of State Lands anticipates no adverse effects from the proposed project. Portland General Electric, Northwest Natural Gas Company, Comcast Cable, Verizon and Qwest Communications were given the opportunity to review this proposal and submitted no comments or objections. j CGc � December 10,2007 PREP BY: Cheryl Caines DATE Associate Planner TVF&R WALNUT STATION(CUP2007-00003) PAGE 30 OF 30 12/17/07 PUBLIC HEARING STAFF REPORT TO THE HEARINGS OFFICER PL CITY of TIGARD vS PL / I I I I GEOGRAPHIC INFORMATION SYSTEM r W %.4 VICINITY MAP 14 111 /,_,/ aa-&ftla > - /_ '-NN CT__ JPPI. alliii CUP2007-00003 TUALATIN VALLEY ftlill a.

Purpose. The purpose of this section is to establish two classes of special variances: 2. "Special adjustments" which are variances from development standards which have their own approval criteria as opposed to the standard approval criteria for variances contained in Section 18.370.020.C. Response: Given the unique characteristics of the site and the nature of the proposed activity, the applicant is requesting a special adjustment to the access and egress standards for driveway spacing. B. Development adjustments. Response: The applicant is not requesting a development adjustment as described in this subsection. C. Special adjustments. 1. Adjustments to development standards within subdivisions... 2. Adjustment to minimum residential density requirements... • 3. For adjustments to density requirements in Washington Square Regional Center... 4. For Modifications to dimensional and minimum density requirements... Response: The applicant is not requesting an adjustment related to any of the sections listed above. 5. Adjustment to access and egress standards (Chapter 18.705). a. In all zoning districts where access and egress drives cannot be readily designed to conform to Code standards within a particular parcel, access with an adjoining property shall be considered. If access in conjunction with another parcel cannot reasonably be achieved, the Director may grant an adjustment to the access requirements of Chapter 18.705 through a Type II procedure, as governed in Section 18.390.030, using approval criteria contained in Subsection 2b below. b. The Director may approve, approve with conditions, or deny a request for an adjustment from the access requirements contained in Chapter 18.705, based on the following criteria: (1) It is not possible to share access; (2) There are no other alternative access points on the street in question or from another street, (3) The access separation requirements cannot be met; • (4) The request is the minimum adjustment required to provide adequate access; - (5) The approved access or access approved with conditions will result in a safe access;and Section 2:Application Narrative 2-13 Tualatin Valley Fire&Rescue Walnut Street Fire Station August 14, 2007 • • (6) The visual clearance requirements of Chapter 18.795 will be met. Response: The proposed fire station is being sited within a residential neighborhood and the east driveway, which will give access to fire apparatus and fire station employees only, will be located approximately 25 feet from the nearest residential driveway on the east. It would not be appropriate for this driveway to share access with a residential use as it is intended for the use of fire trucks and employee vehicles. Additionally, the center access which is between the east and west access will be for exiting fire trucks only; no other vehicles will be permitted to use this driveway. The western access will only serve the visitor parking lot area and will allow for the entry and exit of visitor vehicles and exit only for fire station employees. A gate has been provided at the terminus of the western parking area, restricting visitor access to both the center and eastern driveways. Additionally, in an effort to preserve the sensitive environmental areas on site all development related to the fire station has been concentrated in the southeastern corner of the site. While this has restricted the spacing of the driveways it has allowed the on-site wetlands and waterway to remain undisturbed. The additional trips to and from the site will not add any significant traffic increases onto SW Walnut Street and for safety purposes it is necessary to maintain the separation of vehicles as is further discussed in the Traffic Impact Study and Adjustment Memorandum (Exhibit F) that has been submitted with this application._ 6. Adjustments to landscaping requirements... 7. Adjustments to parking standards... 8. Adjustments to sign code... 9. Adjustments to setbacks to reduce tree removal... 10.

Type Ill applications shall be made on forms provided by the Director as provided by Section 18.390.080 E1; Section 2: Application Narrative 2-15 Tualatin Valley Fire&Rescue Walnut Street Fire Station August 14,2007 • • Response: The correct, Director provided, forms have been completed and submitted with this development application (see the "Application" section at the front of this submittal). 2. Content. Type Ill applications shall: a. Include the information requested on the application form; b. Address the relevant criteria in sufficient detail for review and action; c. Be accompanied by the required fee; d. Include two sets of pre-stamped, pre-addressed envelopes for all persons who are property owners of record as specified in Section 18.390.050C. The records of the Washington County Department of Assessment and Taxation shall be the official records for determining ownership. The applicant shall demonstrate that the most current assessment records have been used to produce the notice list; e. Include an impact study. The impact study shall quantify the effect of the development on public facilities and services. The study shall address, at a minimum, the transportation system, including bikeways, the drainage system, the parks system, the water system, the sewer system, and the noise impacts of the development. For each public facility system and type of impact, the study shall propose improvements necessary to meet City standards 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 the dedication requirements, or provide evidence which supports the conclusion that the real property dedication requirement • is not roughly proportional to the projected impacts of the development. Response: All required forms and submittal information have been included as part of the application package for the proposed development, including the required fee, two sets of pre-stamped and pre- addressed envelopes for the notice, and a narrative addressing all applicable approval criteria. Impacts from the proposed development are addressed as follows: • Transportation System: See Exhibit F, Transportation Impact Analysis (TIA). The TIA identifies the potential transportation system impacts from the fire station. • Drainage System: See Exhibit H, Storm Drainage Report, and Exhibit B, CWS Service Provider Letter. The stormwater will be collected by catch basins and routed to a 100' vegetated bioswale for water quality treatment and detention before being released into the wetland buffer and flowing overland into Krueger Creek. This project will not be using the public storm water system and, therefore, there will be no impact to that system. • Parks System: The proposed project does not have a residential component. Therefore, it is note expected to have an adverse impact on the Parks system. However, the site is adjacent to Jack Park but does not expect to impact the park negatively. Once development of the fire station is complete, the undeveloped portion of the site will be divided from the fire station and • incorporated into Jack Park. • Water System: Water service is available to the site from an existing water main in SW Walnut Street. The necessary improvements to connect to the water main will be completed by the applicant and the proposed improvements are not expected to have any adverse impact on the • City's water system. Section 2:Application Narrative 2-16 Tualatin Valley Fire&Rescue Walnut Street Fire Station August 14, 2007 Revised • • • Sewer System: A sanitary sewer line is available to the site in SW Walnut Street. As with the water service, the applicant will complete the necessary improvements to connect to the service l• and these improvements are not expected to have any adverse impacts on the City's system. • Noise Impacts: Under state law the fire trucks only use their sirens when it is necessary to move traffic out of the way. With the signal on SW Walnut Street, sirens will not be necessary as fire trucks exit the station. After 10pm they try to use their sirens as little as possible and make every effort to just use their lights. Additionally, fire trucks will not use their back-up sensors when backing into a station in a residential neighborhood. The noise impacts should be minimal to the neighborhood. C. Notice of hearing. Response: The applicant understands that a mailed notice of a Type III hearing shall being given by the Director in the manner that is outlined in Section 18.390.050.C.1.a through d and the applicant will, at least ten business days prior to the hearing, post a notice of the hearing on the site, pursuant to Section 18.390.050.C.2 below. Additionally, the applicant will prepare an affidavit of posting concerning the notice and submit the affidavit to make it part of the administrative record. D. Conduct of the hearing. E. The decision process. Response: The applicant understands that the approval or denial of a Type III action shall be based on standards and criteria, set forth in the City's Development Code, which shall relate approval or denial of a discretionary permit application to the development ordinance and, when appropriate, to the comprehensive plan for the area in which the development would occur and to the development • ordinance and comprehensive plan for the City as a whole. F. Notice of decision. Response: That notice of a Type III decision shall be mailed to the applicant and to all parties of record within five business days after the decision is filed by the Review Authority with the Director, is acknowledged and understood by the applicant. G. Final decision Response: The applicant understands that the decision of the Hearings Officer in a Type III action is final, for purposes of appeal; on the date notice of the decision is mailed. It is also understood that any party with standing may appeal a Type III decision to the City Council by filing a Notice of Appeal with the Director within 10 business days of the date notice of the decision is mailed and that the notice shall be in the form specified in Section 18.390.040 G.2(a)(2) and the procedures of Sections 18.390.050 C- F shall be included. • Section 2:Application Narrative 2-17 Tualatin Valley Fire&Rescue Walnut Street Fire Station August 14, 2007 Revised • • Chapter 18.510 RESIDENTIAL ZONING DISTRICTS • 18.510.020 List of Zoning Districts D.

Staff will notify the applicant if additional information or additional copies of the submitted materials are required. CITY OF TIGARD Pre-Application Conference Notes Page 7 of 8 NON•Residentiai Application/Planning Division Section • The administrative deci• sion or public hearing will typically occ�approxlmate 1y 45 to 60 days after an application is accepted as being complete by the Planning Division. Applications involving difficult or protracted issues or requiring review by other jurisdictions may take additional time to review. Written recommendations from the Planning staff are issued seven (7) days prior to the pu heating. A 10-day public appeal period follows all land use decisions. An appeal on this mi Mir would be heard by the Tigard C ; -111 Co u r c i ( . A basic flow chart which illustrates the review process is available from the Planning Division upon request. Land use applications requiring a public hearing must have notice posted on-site by the applicant no less than 10 days prior to the public hearing. This PRE-APPLICATION CONFERENCE AND THE NOTES OF THE CONFERENCE ARE INTENDED TO INFORM the prospective applicant of the primary Community Development Code requirements applicable to the potential development of a particular site and to allow the City staff and prospective applicant to discuss the opportunities and constraints affecting development of the site. BUILDING PERMITS - PLANS FOR BUILDING AND OTHER RELATED PERMITS WILL NOT BE ACCEPTED FOR REVIEW UNTIL A LAND USE APPROVAL HAS BEEN ISSUED. Final inspection approvals by the Building Division will not be granted until there is compliance with all conditions of development approval. These pre-application notes do not include comments from the Building Division. For proposed buildings or modifications to existing buildings, it is recommended to contact a Building Division Plans Examiner to determine if there are building code issues that would prevent the structure from being constructed, as proposed. Additionally, with regard to Subdivisions and Minor Land Partitions where any structure to be demolished has system development charge (SDC) credits and the underlying parcel for that structure will be eliminated when the new plat is recorded, the City's policy is to apply those system development credits to the first building permit issued in the development (UNLESS OTHERWISE DIRECTED BY THE DEVELOPER AT THE TIME IN WHICH THE DEMOLITION PERMIT IS OBTAINED). PLEASE NOTE: The conference and notes cannot cover all Code requirements and aspects relate site planning that should apply to the development of your site plan. Failure of the staff to provide information required by the Code shall not constitute a waiver of the applicable standards or requirements. It is recommended that a prospective applicant either obtain and read the Community Development Code or ask any questions of City staff relative to Code requirements prior to submitting an application. AN ADDITIONAL PRE-APPLICATION FEE AND CONFERENCE WILL BE REQUIRED IF AN APPLICATION PERTAINING TO THIS PRE-APPLICATION CONFERENCE IS SUBMITTED AFTER A PERIOD OF MORE THAN SIX (6) MONTHS FOLLOWING THIS CONFERENCE (unless deemed as unnecessary by the Planning Division).

In such cases, a condition of development approval may be specified which requires the property owner(s) to provide a future improvement guarantee. The City Engineer will determine the form of this guarantee. The following street improvements may be eligible for such a future improvement guarantee: (1.) Walnut Street (2.) Overhead Utility Lines: ® Section 18.810.120 of the Tigard Municipal Code (TMC) requires all overhead utility lines adjacent to a development to be placed underground or, at the election of the developer, a fee in-lieu of undergrounding can be paid. This requirement is valid even if the utility lines are on the opposite side of the street from the site. If the fee in-lieu is proposed, it is equal to $ 35.00 per lineal foot of street frontage that contains the overhead lines. There are existing overhead utility lines which run adjacent to this site along SW Walnut Street. Prior to final building inspection, the applicant shall either place these utilities underground, or pay the fee in-lieu described above. IIISanitary Sewers: The nearest sanitary sewer line to this property is a(n) 8 inch line which is located along north property line. The proposed development must be connected to a public sanitary sewer. It is the developer's responsibility to extend the sewer to serve this development. 7 • Water Supply: The City of Tigard (Phone:(503) 639-4171) provides public water service in the area of this site. This service provider should be contacted for information regarding water supply for your proposed development. Fire Protection: Tualatin Valley Fire and Rescue District (South Division) [Contact: John Dalby, (503) 356-4723] provides fire protection services within the City of Tigard. The District should be contacted for information regarding the adequacy of circulation systems, the need for fire hydrants, or other questions related to fire protection. • Storm Sewer Improvements: • All proposed development within the City shall be designed such that storm water runoff is conveyed to an approved public drainage system. The applicant will be required to submit a proposed storm art OFT16ARD Pre-Appncatton Conference Notes Page 3 of 6 EngIn erfn9O,DartmentSeudan drainage plan for the sit�d may be required to prepare a di-basin drainage analysis to ensure that the proposed s stem WI I accommodate runoff from u streak! rope rties when fully developed. P P , Y p P Y P On-site detention is required. re Storm Water Quality: The City has agreed to enforce Surface Water Management (SWM) regulations established by the Unified Sewerage Agency (USA) (Resolution and Order No. 00-7) which requires 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 impervious surfaces. The resolution contains a provision that would allow an applicant to pay a fee in-lieu of constructing an on- site facility provided specific criteria are met. The City will use discretion in determining whether or not the fee in-lieu will be offered. If the fee is allowed, it will be based upon the amount of impervious surfaces created; for every 2,640 square feet, or portion thereof, the fee shall be $210. Preliminary sizing calculations for any proposed water quality facility shall be submitted with the development application. It is anticipated that this project will require: ® Construction of an on-site water quality facility. ❑ Payment of the fee in-lieu.

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 projected impact upon the City's transportation system. The applicant shall be required to pay a fee based upon the number of trips which are projected to result from the proposed development. The calculatil f the TIF is based on the proposed use of the land, the size of the project, and a general use based ee category. The TIF shall be calculated at the time of building permit issuance. In limited CRY OF T ARO Pre Application Conference Notes Page 4 of 6 Engineering Department Section circumstances, payment of the TIF may be allowed to be deferred until the issuance of an occupancy permit. Deferral of the pays t until occupancy is permissible sly when the TIF is greater than $5,000.00. • Pay the TIF PERMITS Public Facility Improvement (PFI) Permit: Any work within a public right-of-way in the City of Tigard requires a PFI permit from the Engineering Department. A PFI permit application is available at the Planning/Engineering counter in City Hall. For more extensive work such as street widening improvements, main utility line extensions or subdivision infrastructure, plans prepared by a registered professional engineer must be submitted for review and approval. The Engineering Department fee structure for this permit is considered a cost recovery system. A deposit is collected with the application, and the City will track its costs throughout the life of the permit, and will either refund any remaining portion of the deposit, or invoice the Permittee in cases where City costs exceeds the deposit amount. NOTE: Engineering Staff time will also be tracked for any final design-related assistance provided to a Permittee or their engineer prior to submittal of a PFI permit application. This time will be considered part of the administration of the eventual PFI permit. The Permittee will also be required to post a performance bond, or other such suitable security. • Where professional engineered plans are required, the Permittee must execute a Developer/Engineer Agreement, which will obligate the design engineer to perform the primary inspection of the public improvement construction work. The PFI permit fee structure is as follows: NOTE If an PEI Permit is required,the applicant must obtain that permit prior to release of any permits from the Building Division. Building Division Permits: The following is a brief overview of the type of permits issued by the Building Division. For a more detailed explanation of these permits, please contact the Development Services Counter at 503-639-4171, ext. 304. Site Improvement Permit (SIT).

The property owner is considering proposing the construction of an 11,380 square foot fire station on the southeast portion of the lot. The expansion of Jack Park onto the remainder of the property may be possible in the future. These proposed developments are subject to Type III Conditional Use Review in the City of Tigard. Prior to applying to the City of Tigard for the necessary land use approvals,we would like to discuss the proposal in more detail with the surrounding property owners and residents. You are cordially invited to attend a meeting • Tuesday,March 13,2007 Charles F.Tigard Elementary School 12850 SW Grant Street Tigard,Oregon 7:00 pm to 9:00 pm Please note that this will be an informational meeting on preliminary plans. These plans may be altered prior to the submittal of the application to the City. I look forward to more specifically discussing the proposal with you. Please call me at(503) 227-3664 if you have any questions. • Regards, • rank Angelo Project Planner • • . . • • • • NEIGHBORHOOD MEETING INFORMATION As part of the development review process for most land use applications,the City of Tigard : requires that developers hold a neighborhood meeting to notify and discuss With property ,_ owners in the area,their proposed development.Below are some frequently asked questions ' T I G AR D about the neighborhood meeting process. • WHAT IS THE PURPOSE OF THIS NEIGHBORHOOD MEETING? ' • The purpose of the meeting'is to allow the prospective developer to share with you what they are planning to do. This is your opportunity to become informed of their proposed development and to let them know what issues or concerns you have in regard to their proposal. WHAT HAPPENS AFTER THE NEIGHBORHOOD MEETING? After the neighborhood meeting,the prospective developer:finali7es their submittal package (often taking into . account citizen concerns) and submits an application to the City. 'Sometimes it takes a while before the developer's application is•ready to'submit,so there could be several months between the neighborhood meeting and the submittal of an application. Once an application is submitted to the City,Staff reviews it for completeness. Once an application has been deemed complete,the formal application review begins. It takes approximately 6-8 weeks from the time the application is accepted for a decision to be made. Many types of applications require a public hearing at which alk citizens are given the opportunity to provide comments or concerns.. Property owners within 500 feet will be notified after a complete application is submitted. They will be provided an opportunity to comment. Any appeals are decided based on the provisions of applicable laws and the development code. WHAT IF THE PROPOSAL PRESENTED AT THE NEIGHBORHOOD MEETING IS NOT WHAT IS ACTUALLY SUBMITTED? Applicants are not required to submit exactly what was presented at the neighborhood meeting if it generally• follows the type of development proposed. This provides for-tire opportunity to address the neighborhood issues • and address other changes necessitated by the development or staff. If the project is significantly different,a new neighborhood meeting would be required as determined by staff. • HOW DO I KNOW WHAT ISSUES ARE VALID? ' A decision is reviewed based on.compliance with the Tigard Development Code. Review the ao's development code to familiar eyourself with what is permitted and what may not be permitted A copy of the development code is available for viewing at the Tigard City Library,on the City's web site at www.ci..tigard.or.us,Or a copy may purchased at the Community Development Services counter. You may also contact city planning staff and ask what the standards are for a specific issue. Be prepared,however,that you may not LIKE all the standards,but at least you know what they are. If a development meets,the code standards,it can proceed. - For your assistance,attached is a list compiled of helpful questions to ask that may assist you in . determining your position on a particular proposal .: • .

He then introduced Frank Angelo of Angelo Planning Group. Frank read the City of Tigard's supplied statement and then described the land use process (conditional use application, completeness review, hearing in front of a hearings officer) for this application in more depth. Frank also explained that the neighborhood meeting and future application process are for the fire station only and that although there will be some discussion of Jack Park, the park would not be part of the application. He explained that, at a future date, there would be a lot line adjustment to break the fire station away from the unused portion of the lot and that portion would be used for the expansion of Jack.Park. Frank then turned to the site plan board on display and explained that this site plan (Option A) is the preferred option but that there was also an Option B. He went on to explain that the main difference between the two options is the placement of the visitor parking lot and the spacing between the accesses. Frank then introduced Bob Thrapp of Peck Smiley Ettlin Architects to discuss the two options in more detail. Bob described the two options as follows: • Option A: o The center of the building will have drive-through bays for the fire trucks; o The center drive-through bays will be restricted to fire truck access only; o In designing the building they tried to minimize the size of the building to maximize • the amount of space that could be dedicated to the park; o The visitor parking on the west would be shared between the fire station community room and the expanded Jack Park. o There will be parking along the east side of the building for the fire fighters and for any visitors (including emergency parking); o Parking along the west side will be shared between the fire station community room and the expanded park; o The west side access will be gated to the north to restrict access. • Option B: o The building itself is identical to the one in Option A, the biggest difference being the placement of the parking and accesses. o In an attempt to satisfy the requirements of the City's development code, the two accesses were moved as far from each other as possible. o The visitor parking lot on the west side of the structure has been moved further west which makes it closer to the park but makes necessary a longer path between the lot and the community room. • Floor Plan: the floor plan for the two options is identical: o The west side of the building contains a large community room at the north with restrooms; and o The west side will also contain an exercise room for the firefighters and space for them to work on any equipment if necessary. o The center of the building will have'drive-through bays in the center for the fire trucks; o Along the east side of the building there will be dormitories and facilities for the • firefighters. • Elevations: the three elevations shown would be for either option: o Tried to design a building that would fit in to the residential neighborhood and have a more rural feel; Friday,July 27,2007 Page 1 of 5 Tualatin Valley Fire&Rescue:WS Street Fire Station • Neighborhood Meeting Minutes o The portion of the building that would house the fire trucks would resemble a barn with a large red roof and would be sided with board and batten; o The station would be a sage green (typical of TVF&R buildings) and would be sided with cedar shingles; o There will be a brick base around the entirety of the building to tie it all together and there will be canopies over the entrances to ensure they are visible. o There are three versions of the roof for the drive-through bays: typical barn, pitched or a boarder barn-type roof. The meeting was then opened up for questions: Q—Will there be a fee to use the fire station community room? A — (Storm) The community room is open to all community groups for any community activity (neighborhood association or other community activity). The use of the room is encouraged by TVF&R. There is only a fee if there is a commercial aspect to the activity — for example, if an entrance fee is charged or it is a commercial activity. TVF&R activities would be given preference over community activities for use of the room. The City of Tigard is in favor of the community room and asked TVF&R to make the room larger which they did, effectively doubling the size to approximately 1000 square feet. Q—Can the room be split in half? A— (Storm) Yes, the room can be divided in half. Each room would have its own access, bathroom and sink. Q—Which option is preferred? A — (Frank) Option A is preferred. Option B was designed at the City's request to space the two accesses further apart. The application will contain a variance which will demonstrate how the distance between the accesses in Option A is acceptable. • Q—Will there be a new traffic light installed on Walnut Street? A — (Storm) Yes, an emergency vehicle actuated signal will be installed across from the fire station to allow the fire trucks to enter traffic. Q —Will the traffic light be tied to any other intersections? A — (Storm) No, the traffic light installed can only be activated by the drivers of the fire trucks and will only be used to allow the trucks to enter traffic. Q— It is not a regular stop light? A— (Storm) Correct. It will only be used by the fire trucks. Comment: Neighborhood resident stated that he believes the property was ill gotten and he is not in favor of the community room. He believes that any community meetings could be held at nearby schools (CFT Elementary or the middle school). He went on to say that he believes the community room is an additional tax payer's expense and that the expansion of Jack Park will increase the traffic on Walnut Street. Additionally, he says, there are already too many parks for people to use and this all bothers him considerably. Comment: A different neighborhood resident stated that he welcomes both the fire station and the community room and he has two questions: Question 1: Q— How did they come to the architectural design? Comment: The neighborhood resident has seen two examples of fire stations that look like large houses and conform dramatically to their surrounding residential neighborhood. Friday, July 27, 2007 Page 2 of 5 • Tualatin Valley Fire&Rescue:Walnut Street Fire Station Neighborhood Meeting Minutes A — (Bob) TVF&R is trying to develop a set of design standards that each station would be held to. • Internal circulation is very important. Aesthetically, it is important to have a high quality building but with ) low maintenance and an open design. When designing the building they try to determine if it should blend in or stick out. They have tried to make this building blend in with a combination of rural and residential design. Q — Is the design still open for discussion? A — (Frank) Yes, in fact, that is a good topic for this meeting. Although, there are some design parameters from TVF&R that must be followed. Comments from Neighborhood Residents: - Should be more residential looking; - It looks like an industrial or big, box building; - The neighborhood had higher expectations and has a higher standard of design. Q —Why is the building grey? A— It is actually green; it just looks grey in this light. The cedar shingles will be painted a sage green. Q — Why are you using cedar shingles? They are the most flammable type of building material and a brush fire could break out in the park and set the fire station on fire. You should use brick. A — (Bob) Brick will be used along the bottom of the building and the cedar shingles are treated with a fire retardant. Q—Will any stone be used in the design of the building? A— (Bob) No. •) Question 2: Q—There will be plenty of parking spaces, is it possible to put them behind the building? A — (Bob) The placement of the parking was chosen to give as much property to the park as possible. Because of the apparatus route it would be difficult for the parking to go behind the building — it would be a tight fit and not visible to people. Q —The question about the parking is aesthetic—could you design something to hide the parking? A — (Frank) The landscaping is not shown on these site plans but the City does require a landscaping buffer around the parking lot. Comment: The neighborhood resident explains that the street is lower than the property at the location of the parking and suggests a higher than normal buffer. Comment: A different neighborhood resident states that there should be no buffering around the parking lot — that it should be completely open to the street and park — and closer to the community room for safety reasons when people leave meetings at night. Q —Will the fire truck sirens frequently go on and off? A — (Storm) Under state law the fire trucks only use their sirens when it is necessary to move traffic out of the way. With the signal on SW Walnut Street, sirens will not be necessary as fire trucks exit the station. After 10pm they try to use their sirens as little as possible and make every effort to just use their lights. TVF&R try to be excellent neighbors and try to accommodate the surrounding neighbors as much as possible. For example, they don't use their back-up sensors when backing into a station in a residential neighborhood. •) Q —What kind of fire engines will be at the station? A — (Storm) A structural fire fighter. The station could potentially accommodate any apparatus, if necessary. Friday,July 27,2007 Page 3 of 5 Tualatin Valley Fire&Rescue:Wet Street Fire Station • Neighborhood Meeting Minutes Q—Will there be any emergency vehicles (ambulances) at the station? A — (Storm) No, ambulance services are provided by Metro West. TVF&R owns a few ambulances 40 which are only used for back-up or in an extreme emergency. Q—Will the vehicles be parked inside? A— (Storm) Yes, the trucks can not be allowed to get to cold or freeze because of the water inside. The parking to the west of the building will be strictly for the park and community room. Storm then introduced Daniel Plaza from the City of Tigard to talk about the future expansion of Jack Park. Dan explains that this project has been endorsed by the City Council who felt it was important to extend the park south of the Creek. The community room is great for partnering and for having meetings and they asked TVF&R to make the room bigger. It will be possible for the room to be divided in half and while there are meeting spaces in central Tigard it is important to have additional meeting spaces out in the neighborhoods. Dan explains that the City Council was really the driving force behind this project. Jack Park has been in the neighborhood for a long time and is essentially a neighborhood park that serves the people who live around it and that will probably not change with an expansion. Dan that shows the two draft site plans for the park and describes them as follows: • Option A: o Builds off the architect's Option A; o Play structure and parent's seating area to the west of the parking area. The playground is for very young children (a tot lot) and the parking will be close to the community room. Between the play structure and the community room will be turf. o There will be a Creek crossing that will hook up to the existing trail system and connect to the existing portion of Jack Park. • Option B: o Basically the same but with the parking area moved and the tot lot shifted. o Will still have the Creek crossing. Dan then started taking questions from the neighborhood residents. Q—Who preferred Option B? A— (Frank) The City development code requires the driveways to be further apart. Q — Has a demographic study been done of the neighborhood to find out the age of the children living near the park? There are not a lot of very young children in the neighborhood who would use that type of play structure. Will it be utilized? A— (Dan) There is currently a play structure for elementary school aged children in the existing portion of Jack Park. We wanted to have a feature in the expanded portion of the park near Walnut Street that would be recognizable to people driving by. Comment: The neighborhood resident is not against a tot lot but would like some justification for that choice. Dan replied that it is important to remember that the demographics of a neighborhood change but he is open to finding out the information. Other suggestions for a feature along Walnut Street included a gazebo but not a skate park. Comment: The neighborhood resident doesn't think that Jack Park needs to be expanded and they are against the placement of the fire station. The park is not well utilized. The resident than reiterates the • other resident's request for a demographic or utilization study. Friday, July 27, 2007 Page 4 of 5 • • Tualatin Valley Fire&Rescue:Walnut Street Fire Station Neighborhood Meeting Minutes Comment: A different neighborhood resident states that expanding the park is a total waste of tax payer's money and that there is already a sign at 124th Street advertising the park and there is no need for a recognizable feature along Walnut Street. Dan explains that the City of Tigard has a goal to have an active park within a half of a mile of every residential home in the city if there are children living nearby. Comment: This neighborhood resident believes that the creation of the park is very beneficial to the neighborhood and welcomes the park. Comment: A neighborhood resident states that the traffic is already too fast on Walnut Street and there is no way for her to cross the street to get to the park safely. Dan suggests the resident contact the appropriate City agency if there are problems with traffic on Walnut Street. Comment: How will people cross Walnut Street to get to the park? The Creek crossing should be at the southwest end of the Creek and connect to the trail system which should extend to the sidewalk on the west end and a pedestrian crossing with a light where the trail comes out should be installed across Walnut. This would tie in with the Master Plan for trails. Comment: Neighborhood resident is in favor of the park and enjoys taking their kids there but it is difficult to cross the street and parking is extremely limited. Thinks the park would be better utilized if there were better parking. The resident loves the idea of a gazebo that could be used in conjecture with • the community room. Thinks it would be nice to have live music and concerts. Comment: Neighborhood resident doesn't want any more noise coming out of the park. Hans makes the comment that it is his experience over time that TVF&R makes excellent neighbors — they provide open space, are clean and provide 24-hour security. The meeting was then brought to a close. Neighborhood residents were encouraged to stay involved in the process and were told that future notices concerning the project would be sent to them.

Tualatin Valley Fire&Rescue Walnut Street Station and Community Center July 2007 Transportation Impact Study Page i • • 0 DKS Associates TRANSPORTATION SOLUTIONS Chapter 1 • Introduction and Summary The transportation impacts for the proposed Tualatin Valley Fire&Rescue(TVF&R)Walnut Street Station and Community Center are presented in this report. Analysis conducted for the proposed project determines if the study area transportation system performance will meet standards established by the City of Tigard with the development of the project. The proposed project site is located on the north side of SW Walnut Street between SW Gaarde Street and SW 1215`Ave in Tigard,Oregon. The project site is currently vacant. The proposed project will include one building with two separate land uses. The proposed 11,115 square foot fire station will consist of a three bay garage staffed on a 24 hour basis with four employees. The fire station will service north and northwest Tigard,including Summer Lake,north and northeast Bull Mountain area, and portions of southern Beaverton with the goal of reducing emergency response time to these areas. The proposed 767 square foot community center will serve as a meeting place for small,local-interest groups such as gardening clubs and Boy Scouts. Project Transportation Impacts • While all modes of travel are evaluated,the motor vehicle issues are the most significant in the project study area. Transportation system performance was analyzed for intersection and roadway operations, safety,circulation and multi-modal access. For the motor vehicle system,level of service D is the City's minimum acceptable intersection service level during peak periods for both signalized and unsignalized intersections'. Project traffic impacts were evaluated for the weekday morning peak period(7 AM to 9 AM)and evening peak period(4 PM to 6 PM),when traffic volumes within the study area are highest.Trip generation for the proposed project was estimated based on the anticipated number of fire station employees and published trip generation rates for the community center provided by the Institute of Transportation Engineers(ITE) for similar land use types2. The proposed project would add 9 vehicle trips in the AM peak hour and 16 vehicle trips in the PM peak hour. The additional traffic associated with the proposed TVF&R Walnut Street station combined with future background traffic growth within the study area would not have a significant operational impact at any of the study intersections during the peak periods analyzed. All study intersections would meet the City's intersection performance standards during each of the peak periods analyzed. Access Spacing The project proposes three new access points along the north side of SW Walnut Street. The three accesses will be needed to adequately serve the two separate uses at the site.Based on the collector functional classification'of SW Walnut Street,the minimum access spacing requirement is 200 feet between roadways and driveways. The proposed site access points would not conform to City access 'City of Tigard Transportation System Plan,Chapter 8,Page 8-32. 2 Trip Generation Manual, 76 Edition,Institute of Transportation Engineers,2003,Code 495. 3 City of Tigard Transportation System Plan,February 7,2002,Figure 8-3. Tualatin Valley Are&Rescue Walnut Street Station and Community Center July 2007 Transportation Impact Study Page 1 • DKS Associates (S TRANSPORTATION SOLUTIONS spacing standards. An adjustment of access spacing requirements has been requested for the proposed project. An access spacing adjustment at the proposed site is not expected to significantly impact the operating conditions or safety of SW Walnut Street. Sight Distance The proposed west access was the focus of the sight distance evaluation. The west access would allow entry and exit for visitor vehicles and exit only for fire station employees. The proposed central access would be controlled by an emergency traffic signal. The proposed east access would serve as an entrance only for emergency vehicles and fire station employees. Therefore sight distance requirements only apply to the proposed west access. Based on a recent speed survey conducted on SW Walnut Street along the project site frontage,the 85th percentile speed is 40 miles per hour westbound and 43 miles per hour eastbound. The posted speed limited on SW Walnut Street along the project site frontage is 30 miles per hour. The City of Tigard"'utilizes AASHTO standard's for sight distance evaluation.Based on the observed speed of 40 miles per hour,a minimum of 440 feet of sight distance would be required at the west access. A field measurement at the proposed location of the west access found 390 feet of available sight distance looking east and more than 800 feet of available sight distance looking west. The west access would not meet sight distance standards based on the speed survey data. Project Related Mitigation Measures • Several transportation mitigations were identified for the proposed project. Based on the operations analysis conducted for the proposed project,no off-site deficiencies were identified. Project related on-site mitigation measures include: • An emergency vehicle traffic signal is recommended at the proposed central driveway on SW Walnut Street. • Relocate the west access approximately 10 feet to the west to align with the residential driveway across SW Walnut Street.This will reduce potential conflicts between vehicles turning left into these driveways. • There is a significant speeding issue on SW Walnut Street today. The 85th percentile speed is more than 10 miles per hour higher than the posted speed limit. Traffic calming methods such as increased speed limit enforcement should be implemented to reduce vehicle speeds and potential safety issues. • A 35 mile per hour speed on SW Walnut Street would require a minimum sight distance of 390 feet which would be met by the proposed west access. The project applicant should work with the City to reduce the 85th percentile speed to a more reasonable speed of approximately 35 miles per hour. • Obtain an adjustment of access spacing requirements for the three proposed accesses on SW Walnut Street from the City of Tigard. An access spacing adjustment at the proposed site is not expected to significantly impact the operating conditions or safety of SW Walnut Street. • 4 City of Tigard Municipal Code 18.705.030.H.I.

Existing operating conditions of roadways and key intersections in the study area are also discussed. i Roadway Network The project site is located on SW Walnut Street,just west of SW 124th Avenue in the City of Tigard. Figure 1 shows the study area,study intersections,existing lane geometries and turn movement volumes for the peak hours of analysis. Key roadways in the study area include SW Walnut Street, SW Gaarde Street and SW 121'Avenue. These roadways serve as the primary connections to and from the site. These key roadways are characterized in Table 1.

SW Gaarde Street and SW 121#Avenue both have a posted speed of 35 miles per hour near their intersections with SW Walnut Street. On-street parking is not permitted on any of the key roadways in the study area. All three roadways provide sidewalks on both sides of the street within the study area.Additionally, SW Walnut Street and SW Gaarde Street both provide bike lanes on both sides of the street. SW 12151 Avenue does not have bike lanes within the study area.The City of Tigard classifies SW Gaarde Street as an arterial,and SW Walnut Street and SW 1215L Avenue as collectors. All other roadways within the study area are classified as local streets or private roadways. / s Tigard Municipal Code—Title 18:Community Development Code 18.703.030 H2. • Tualatin Valley Are&Rescue Walnut Street Station and Community Center July 2007 Transportation Impact Study Page 3 • • SW 121st AVE • L o[vi�N eI 4 k> SW 122nCS gp(27) dAve M a 267(211) i4 ; P 21(32) 86(79).1 157(234)=4a 41(205)", h1 t e, dc"` 0 C N O SW 123rd Ave SW 124th Ave SW Blue 14e01 'Oi Project :.: .. j Z J go v l'''-‘ (,) , 4., 48(106) SW 128th Ave Ito, 4 e141(308) 1e 4 G' N N... // SW 129th Ave ..0 SW GAARDE ST LEGEND DKS Associates 1 Figure El O - Study Intersection T?Mr:SNOPTAT!ON•SG UT1S 1■ - Existing Lane Configuration STUDY AREA At g Q- Existing Traffic Control (-) EXISTING CONDITIONS cow -AM(PM)Peak Hour Traffic Volumes ` .__/ a - Traffic Volume Turn Movement NO SCALE • • • DKS Associates TRANSPORTATION SOLUTIONS Existing Volume and Speed Survey A 24-hour traffic volume and speed survey6 was conducted on SW Walnut Street along the project frontage.

Table 2: Daily Volume and Speed Survey Data-SW Walnut Street Direction Daily Volume 85th Percentile Speed Eastbound 4,370 43 mph Westbound 4,800 40 mph Total/Average 9,170 42 mph The observed travel speeds on SW Walnut Street along the project frontage are significantly higher than the 30 mile per hour posted speed. This existing speeding issue should be evaluated further to identify any associated safety impacts and determine an appropriate course of action. Influence Area and Existing Driveways • According to the City of Tigard access-study requirements',the"influence area"for a proposed development site is determined by City engineers.For this analysis,the influence area on SW Walnut Street was identified from SW Gaarde Street to SW 12151 Avenue.Figure 2 shows the SW Walnut Street influence area for the proposed project site.Included in this figure are all roadway segments, intersections and access points within the project influence area. As shown in Figure 2,the project site currently has one access located on the north side of SW Walnut Street. Existing Traffic Operations While analysis of traffic flows is useful in attempting to reach an understanding of the general nature of traffic in an area,traffic volume alone indicates neither the ability of the street network to carry additional traffic nor the quality of service provided by the street facilities.For this reason,the concept of level of service(LOS)has been developed to correlate traffic volume data to subjective descriptions of traffic performance at intersections. Intersections are the controlling bottlenecks of traffic flow,and the ability of a roadway system to carry traffic efficiently is nearly always diminished in their vicinity. An intersection's level of service(LOS)is similar to a"report card"rating,based on average vehicle delay.Level of service"A",`B"and"C"indicate conditions where vehicles can move freely.Level of service D and E are progressively worse. For signalized intersections, level of service F represents conditions where the average delay for all vehicles through the intersection exceeds 80 seconds per vehicle,generally indicated by long queues and delays.Under this operating condition, delay is highly variable,and it is difficult to estimate average delay accurately because congestion often extends into and is affected by adjacent intersections.

Based on City of Tigard guidelines,the following intersections were selected for analysis: • SW Walnut Drive/SW 121n Avenue • SW Walnut Drive/SW Gaarde Street To determine intersection operation levels,intersection turn movement counts were conducted at study area intersections during the morning(7 AM to 9 AM)and evening peak(4 PM to 6 PM)period?. Existing peak hour operating conditions were determined based on 2000 Highway Capacity Manual'° methodology for signalized and unsignalized intersections.The SW Walnut Street intersections at SW Gaarde Street and SW 12151 Avenue are controlled by a traffic signal today. Traffic counts and level of service calculation sheets are included in the technical appendix. The existing study intersection turn movement volumes are shown in Figure 1. All of the study intersections currently operate at LOS C and meet the City's intersection operating criteria of LOS D during the AM and PM peak hours. The existing study intersection operating conditions"are shown in Table 3.

The study intersection of SW Walnut Street/SW Gaarde Street experienced three collisions over the previous three years.Eleven collisions occurred at SW Walnut Street/SW 1215`Avenue over the previous three years.An additional collision took place along SW Walnut Street within the study area,between the study intersections.The equivalent collision rates per million entering vehicles(MEV)are shown in Table 4 and currently do not indicate any safety related problems at this time. Typically a collision rate greater than one collision per million entering vehicles indicates a potential safety related problem.

Project Description The proposed Tualatin Valley Fire&Rescue(TVF&R)Walnut Street Station and Community Center would be located on the north side of SW Walnut Street between SW Gaarde Street and SW 12155 Ave in Tigard,Oregon(Tax Lot ID#2S 104AD04500).The project site is currently vacant. The proposed project will include,one building with two separate land uses. The proposed 11,115 square foot fire station will consist of a three bay garage staffed on a 24 hour basis with four employees. The fire station will service north and northwest Tigard,including Summer Lake,north and northeast Bull Mountain area,and portions of southern Beaverton with the goal of reducing emergency response time to these areas. The proposed 767 square foot community center will serve as a meeting place for small, local-interest groups such as gardening clubs and Boy Scouts. • Trip Generation and Distribution Trip generation for the proposed project was estimated based on employee shift information, community center utilization and compared with published trip generation data provided by the Institute of Transportation Engineers(ITE)13.Vehicle trips to and from the project site were estimated for morning peak(7 AM to 9 AM)and evening peak(4 PM to 6 PM)hours. As shown in Table 5,the proposed project would generate approximately 9 new AM peak hour vehicle trips and 16 new PM peak hour vehicle trips.

This would result in four trips entering the site and four trips exiting the site during the AM peak hour. No shift changes are expected to take place during the PM peak hour. However,one trip entering the site and one trip exiting the site was assumed during the PM peak hour to account for potential visitor or delivery trips. Emergency vehicle trips would be an uncommon and random occurrence,therefore no emergency vehicle trips are expected during the AM or PM peak hours. • The available ITE trip generation rates for Recreational Community Centers are based on a small sample size of data. It was determined a more appropriate trip generation estimate for the community center should be based on the proposed building area,potential occupancy and occurrence of events. The community center was anticipated to hold on average approximately 15 people based on its size of 767 square feet'm. A worst-case scenario was then developed based on the assumption that community center events would begin during the PM peak hour,resulting in 15 vehicle trips entering the site.A single exiting vehicle during the PM peak hour was assumed to account for potential drop-off trips. Trip distribution was based upon existing traffic patterns at the study area intersections.Figure 3 illustrates the estimated distribution of project vehicle traffic on the surrounding street network.Trip distribution is shown directionally in that it is assumed that project trips do not necessarily originate from and return to the same location.It is assumed that during the AM peak hour for example,entering project trips originate from households and are destined to the project site while exiting trips are destined to households or commercial centers. It is assumed that during the PM peak hour project trips both originate from and are destined to households or commercial centers as people come from their homes, errands,and work places to use the community center. `• Intersection Capacity Study intersection capacity was analyzed for the proposed project during the AM and PM peak hours. The analysis focused on three operating condition scenarios: • Existing Conditions(previous section) • 2009 Background Conditions • 2009 Background plus Proposed Project Conditions Existing plus 2009 Background This scenario estimates traffic conditions within the study area prior to the construction of the proposed fire station and community center. Construction of the proposed project is assumed to be completed by 2009. There are currently no approved projects near the study area which would impact future traffic volumes. Future 2009 background traffic growth volumes were added to the existing roadway network to determine intersection operating conditions prior to the construction of the proposed project. Future growth at study intersections was estimated at roughly two percent per year for a total of a four percent increase in traffic volumes by 2009. Table 6 summarizes the 2009 background scenario operating conditions for the AM and PM peak hours.Figure 4 illustrates the 2009 background scenario traffic volumes at study intersections. to Conversation with Gary Wells,Tualatin Valley Fire&Rescue,June 19,2007.

Signal warrants were not met for either of the proposed access points during any of the peak periods analyzed.ODOT's emergency traffic signal policy warrants an emergency traffic signal when roadway volumes exceed 8,850 vehicles per day.Results from 24-hour traffic counts provided a result of 9,167 vehicles per day,thus fulfilling the emergency signal traffic warrant16.The traffic signal warrant analysis was conducted consistent with methods outlined by the Oregon Department of Transportation(ODOT)"and is included in the technical appendix. Turn Lane Requirements Right turn lane warrants were evaluated at the proposed employee and visitor entrances during the AM and PM peak hours.No right turn lanes are warranted at the proposed access points.A summary of the • turn lane warrant analysis is included in the technical appendix. Site Access The project site plan was evaluated to determine the appropriate on-site circulation and access needs based on the proposed land uses. The fire station emergency vehicles would require a separate exit `0 with signalized emergency vehicle control which would stop traffic on Walnut Street when a fire truck is exiting.No other vehicles would be allowed at this access to eliminate any potential impacts to emergency response time. The emergency vehicles would need a separate entrance which allows them access to the rear of the fire station garage so the fire trucks can be parked facing Walnut Street. An option to this configuration would be to have the fire trucks back into the fire station garage, however the impacts to traffic operations on Walnut Street could be significant. The community center would need its own parking lot area with a separate access(entry and exit)from the fire station. It is not desirable to mix public vehicles with emergency vehicles. The fire station employees would utilize the emergency vehicle entrance to enter the site and the community center access to exit the site. The project proposes three new access points along the north side of SW Walnut Street.The three accesses will be needed to adequately serve the two separate uses at the site. The new access points are described below and shown in the influence area map(Figure 2). • The east access would serve as an entrance only for emergency vehicles and fire station employees. • The center access would serve as an exit only for emergency vehicles. This access would be controlled by an emergency vehicle traffic signal. • The west access would serve the visitor parking lot area. The access would allow entry and exit for visitor vehicles and exit only for fire station employees. rs Manual on Uniform Traffic Control Devices,Part 4,2000 Edition. 16 ODOT Traffic Signal Policy and Guidelines 2006,Section VI.A.I. 17 Oregon Department of Transportation,Analysis Procedures Manual,-March 2007. 1111 Tualatin Valley Fire&Rescue Walnut Street Station and Community Center July 2007 Transportation Impact Study Page 16 • • • • DKS Associates • TRANSPORTATION SOLUTIONS The access spacing standard for Walnut Street was evaluated to determine if the three proposed accesses at the project site would meet standard. Based on the collector functional classification's of Walnut Street,the minimum access spacing requirement is 200 feet between roadways and driveways. The proposed site access points would not conform to City access spacing standards. As shown in Figure 2,the project site has approximately 465 feet of frontage on the north side of Walnut Street. The west access would be located more than 200 feet from the nearest existing driveway to the west(on the north side of the sheet). The central access would be located approximately 25 feet from the west access and 50 feet from the east access(both measured edge of driveway to edge of driveway). The east access would be located approximately 25 feet from the nearest existing driveway to the east(on the north side of the street). The influence area of the project site is defined as the project frontage plus 200 feet on either side of the site. Within the project site influence area on SW Walnut Street,there are currently 15 driveways to single family residences and one intersection(SW Walnut Street/SW 124t Avenue). Due to the large number of existing driveways within the influence area,it is not possible to provide access to the project site that would meet the City's access spacing standards for SW Walnut Street. All of the 15 driveways serve either one,or in a few cases two, single family dwelling units. Therefore each existing driveway within the influence area serves approximately five inbound trips and five outbound trips per day. SW Walnut Street was recently improved to provide a center left turn lane to facilitate access to the driveways in the influence area. Considering the low volume of traffic utilizing the existing driveways in the influence area and the projected low volume of traffic to the site,there are • not expected to be significant safety related issues with the proposed three driveways to the site. The proposed accesses at the Walnut Street TVF&R Fire Station and Community Center would not meet access spacing standards. An adjustment of access spacing requirements will be requested concurrently with this transportation impact study to allow the development of the proposed project. An adjustment of access spacing would be acceptable based on the following findings. • The center access would not operate as a typical driveway. It would serve as an exit only for emergency vehicles with low traffic volumes spread throughout the day. This access would be controlled by an emergency vehicle traffic signal which would eliminate potential vehicle conflicts associated with stop sign controlled driveways. • • The east access would only allow emergency vehicles and fire station employees to enter the site. The traffic volumes at this driveway would be low and spread throughout the day. The project would generate approximately four AM peak hour vehicles and one PM peak hour vehicles at the east access. The entrance only restriction would reduce potential vehicle conflicts associated with full access driveways. • The west access allows fire station employees to exit the site and community center visitors full access to the site. Traffic volumes at this access would be low with approximately five AM peak hour vehicles and 16 PM peak hour vehicle. • Due to the unique nature of the uses at the project site,three separate driveways are recommended. The emergency vehicles have specific needs for site egress and ingress that can not be met with a combined access. It is desirable to have the community center vehicles separated from the emergency vehicles. • 18 City of Tigard Transportation System Plan,February 7,2002,Figure-8-3. Tualatin Valley Fire&Rescue Walnut Street Station and Community Center July 2007 Transportation Impact Study Page 17 • DKS Associates (10 TRANSPORTATION SOLUTIONS • The project site currently has one full access onto SW Walnut Street. The proposed site plan would add one new entrance only access point and one new exit only access point(controlled by an emergency traffic signal)onto SW Walnut Street. Based on the above findings,an access spacing adjustment at the proposed site is not expected to significantly impact the operating conditions or safety of SW Walnut Street. The proposed access points at the project site were evaluated to determine potential operational and safety issues. SW Walnut Street along the project frontage is a three lane roadway which provides a center two-way left-turn lane. The west access should be relocated approximately 10 feet to the west to align with the residential driveway across SW Walnut Street.This will reduce potential conflicts between vehicles turning left into these driveways. Driveway Sight Distance The proposed west access was the focus of the sight distance evaluation. The west access would allow entry and exit for visitor vehicles and exit only for fire station employees. The proposed central access would be controlled by an emergency traffic signal. The proposed east access would serve as an entrance only for emergency vehicles and fire station employees. Therefore sight distance requirements only apply to the proposed west access. Based on a recent speed survey conducted on SW Walnut Street along the project site frontage,the 85t percentile speed is 40 miles per hour westbound and 43 miles per hour eastbound. The posted speed limited on SW Walnut Street along the project site frontage is 30 miles per hour. The City of 411 Tigard19 utilizes AASHTO standards for sight distance evaluation.Based on the observed speed of 40 miles per hour,a minimum of 440 feet of sight distance would be required at the west access. A field measurement at the proposed location of the west access found 390 feet of available sight distance looking east and more than 800 feet of available sight distance looking west. The west access would not meet sight distance standards based on the speed survey data. However,the west access would meet sight distance standards if the 85th percentile speeds on SW Walnut Street could be reduced to a more reasonable 35 miles per hour which is five miles per hour over the posted speed limit. There is a significant speeding issue on SW Walnut Street today. The 85th percentile speed is more than 10 miles per hour higher than the posted speed limit. Traffic calming methods such as increased speed limit enforcement should be implemented to reduce vehicle speeds and potential safety issues. 19 City of Tigard Municipal Code 18.705.030.H.1. • I• Tualatin Valley Fire&Rescue Walnut Street Station and Community Center July 2007 \\ Transportation Impact Study Page 18 • DKS Associates TRANSPORTATION SOLUTIONS Parking The City of Tigard Community Development code20 requires off-street parking based on building area for community center and emergency service land uses.The fire station is proposed to have a building area of 11,115 square-feet. The community center is proposed to have a building area of 767 square- feet. Based on these building areas,the proposed project would require a minimum of 32 vehicle parking spaces. The site plan for the proposed project indicates a total of 39 parking spaces on the site. The proposed parking supply meets the minimum City standard. City code requires one handicapped space for parking lots containing 26-50 parking spaces21. The site plan includes two handicap parking spaces therefore the City handicap parking requirement is met. The city also requires that at least five percent of total long-term parking spaces be reserved for carpool/vanpool use.22 Assuming the 14 proposed fire station parking spaces are long-term(parking more than eight hours),than one designated carpool/vanpool parking space would be required. The site plan includes two carpool parking spaces therefore the City carpool parking requirement is met. The on-site parking analysis is summarized in Table 9.

Project Related Mitigation Measures Several transportation mitigations were identified for the proposed project. Based on the operations analysis conducted for the proposed project,no off-site deficiencies were identified. Project related on-site mitigation measures include: • An emergency vehicle traffic signal is recommended at the proposed central driveway on SW Walnut Street. • Relocate the west access approximately 10 feet to the west to align with the residential driveway across SW Walnut Street. This will reduce potential conflicts between vehicles turning left into these driveways. • There is a significant speeding issue on SW Walnut Street today. The 85th percentile speed is more than 10 miles per hour higher than the posted speed limit. Traffic calming methods such as increased speed limit enforcement should be implemented to reduce vehicle speeds and potential safety issues. • A 35 mile per hour speed on SW Walnut Street would require a minimum sight distance of 390 feet which would be met by the proposed west access.The project applicant should work with the City to reduce the 85th percentile speed to a more reasonable speed of approximately 35 miles per hour. • Obtain an adjustment of access spacing requirements for the three proposed accesses on SW Walnut Street from the City of Tigard.

This request for adjustment addresses the access requirements as stated in the Tigard Community Development Code'. The following sections present the evaluation of the proposed project access points on Walnut Street. The study area and influence area for the proposed project are shown in Figures 1 and 2. The project site plan is attached. Project Description The proposed project site is located on the north side of SW Walnut Street between SW Gaarde Street and SW 1215`Ave in Tigard,Oregon(Tax Lot ID#2SI04AD04500).The proposed project will include one building with two separate land uses. The proposed fire station will consist of a three bay garage staffed on a 24 hour basis with four employees. The fire station will service north and northwest Tigard,including Summer Lake,north and northeast Bull Mountain area,and portions of southern Beaverton with the goal of reducing emergency response time to these areas.The proposed community center will serve as a meeting place for small, local-interest groups such as gardening clubs and Boy Scouts. Proposed Access Evaluation The project site plan was evaluated to determine the appropriate on-site circulation and access needs based on the proposed land uses. The fire station emergency vehicles would require a separate exit with signalized emergency vehicle control which would stop traffic on Walnut Street when a fire truck is exiting.No other vehicles would be allowed at this access to eliminate any potential impacts to emergency response time.

The influence area of the project site is defined as the project frontage plus 200 feet on either side of (• the site. Within the project site influence area on SW Walnut Street,there are currently 15 driveways to single family residences and one intersection(SW Walnut Street/SW 124th Avenue).

Therefore each existing driveway within the influence area serves approximately five inbound trips and five outbound trips per day. SW Walnut Street was recently improved to provide a center left turn lane to facilitate access to the driveways in the influence area. Considering the low volume of traffic utilizing the existing driveways in the influence area and the projected low volume of traffic to the site,there are not expected to be significant safety related issues with the proposed three driveways to the site. Adjustment Request The proposed accesses at the Walnut Street TVF&R Fire Station and Community Center would not meet City of Tigard access spacing standards. An adjustment of access spacing requirements is requested to allow the development of the proposed project. An adjustment of access spacing would be acceptable based on the following findings. The center access would not operate as a typical driveway. It would serve as an exit only for emergency vehicles with low traffic volumes spread throughout the day. This access would be controlled by an emergency vehicle traffic signal which would eliminate potential vehicle conflicts associated with stop sign controlled driveways. The east access would only allow emergency vehicles and fire station employees to enter the site. The traffic volumes at this driveway would be very low and spread throughout the day. The project would generate approximately four AM peak hour vehicles and one PM peak hour vehicles at the east access. �• 2 City of Tigard Transportation System Plan,February 7,2002,Figure 8-3. • • Kim McMillan July 24,2007 Page 5 The entrance only restriction would reduce potential vehicle conflicts associated with full access driveways.

The tree plan for the site is as follows: - • I concur with the need to.remove Tree.Number 17.. Additionally I recommend removal of Tree Number 2 as it appears to be 4 feet or less from the edge of the proposed:parking lot. If it'remains it will be severely by removal of nearly 50% of its root system. There will also be continuing conflicts with limb spread into the parking lot that will require pruning more than 30 percent of the -.--- tree's crown. • The program to save existing trees will be accomplished by placing Tree Protection Fences around tip all trees to be protected and by requiring an International Society of Arboriculture aborist to supervise all work within Tree Protection Zones and all work within Tree Protection Fences. Details of the protection measures can be found in the attached checklist"Tree Protection:Plan". All items in the check list apply to this project. Trees numbered 6 though 13 are deep within the'Vegetated Corridor and are protected by Krueger Creek. These trees will not require Tree Protection Fencing. All other remaining trees will require Tree Protection Fences. • The tree protection program for trees during and after construction has been addressed with the attached check list titled "Tree Protection Plan". • There is no evidence of recent tree removals on site during the past year. Any subsequent tree removals will conform to City of. Tigard Ordinance 18.790. 7 Respectfu.ilq; ■ Kay tyo Tree Care & Landscapes Unlimited, Inc.

I. Before Construction: Pop. Non-Apo. _ . X] ❑ a. Identify.and number,the.trees to be.protected, verify by mapping and/or tagging and note..their .size In D.B.H. (Diameter at Breast Height), variety, health'and'structural conditions, review plans. Xi ❑ b. Check with local government agencies for tree protection'ordiriances. N ❑ c. Remove any'low limbs that may be in the way'of construction equipment, and prune as needed to adhere NM standards.• N ❑ d. Leave a protective covering on the soil, i.e., existiing`groundcover or mulch. 21 ❑ e. Notify all other contractors that these trees are to be saved and protected. ditIffi ❑ f. Install a temporary 6' high metal no-climb fence to protect the trees and their root systems. ) Install tree protection sign on fence. Posts located 10' on center as a general rule. For every inch in diameter of the trunk (D.B.H.) allow.up to•1 foot of radius from the trunk as the - protected area. (Example:' 24" D.B.H. ='24' radius of protected root system.) Ideally, we need to protect more than the drip zone. The drip zone into the trunk is the support roots that hold the tree up. The roots from that drip zone out provide riutritiion "water and oxygen: Try to avoid loss of more than 30% of root on any one side. This allows some encroachment within • the drip line.' This should.be determined on a case by case site conditions.reviewed. (SEE'- ENCLOSED SITE PLAN),. . . 30 ❑ g. Identify any insect or disease problems that may require treatment.- • . [X ❑ h. Engineer and design proposed structures and construction to avoid root loss. Bridge type foundations can save major.roots: . Eil ❑ i. Design landscape islands and planting areas large enough to accommodate trees at maturity. rX ❑ j. Plant the right tree in the right place. Avoid future conflicts with buildings and utilities. • ta ❑ k. Have an experienced Arborist review landscape plan to assure the right tree is planted in the right place and proposed changes don't kill retained mature trees. N ❑ I. Consider tree removals adjacent to trees to be saved for wind related stability concerns. .• App. Non-App. • 24 ❑ m. Check for past and proposed grade and drainage changes, consider the effects. gi ❑ n. Check trees for stability. 1ffi ❑ o. Remove all trees that would not survive the effects of change. Remove all hazardous trees. It 0 p. Minimize environmental changes. IL Purina Construction: . DI ❑ a. Keep equipment off of the root system to avoid compaction. ❑ b. Keep equipment away from structure to prevent damage to trunk and limbs. X ❑ c. Don't allow chemicals to be dumped on the ground near the tree, i.e., gasoline, diesel, paint, herbicide, cleaner, thinners, etc. X ❑ d. Provide means of temporary irrigation if the project runs through the summer. X ❑ e. If roots or limbs are cut or damaged, have them inspected by an ISA Certified Arborist and repaired or treated according to his/her recommendations. ❑ f. Protect the trees from excessive heat, i.e., equipment, paving and/or burning. it ❑ g. Avoid trenching through the root systems, boring under them or hand digging can save roots. IN ❑ h. Contact the ISA Certified Arborist familiar with the site prior to and during any activity within the drip zone or tree protection fencing for consultation.. III. After Construction: 21 ❑ a. Carefully landscape the area under the tree, being careful of the roots and structure. Use plantings that will live under the same conditions as that of the tree. IX ❑ b. Provide insect and disease control, fertilization and pruning as needed or adhere to long-term protection plan if provided. 2 ❑ c. Avoid direct irrigation spraying onto the trunk. The amount of irrigation needed to keep new plantings alive can often be enough to kill mature trees. I ❑ d. Do not cover existing root systems with more than 2" of soil. The more soil you add, the greater the chances of damaging the root system. 21 ❑ e. Provide irrigation and/or drainage to emulate pre-construction conditions. NOTE: This tree protection plan identifies construction protection measures to prevent unwarranted tree loss. The identified measures limit the amount of earth disturbance surrounding the trees, and limit the removal of the tree's root systems. Due to the variation of every project, it is unlikely all of the above identified measures can be practicably applied to each individual tree; nor is it likely each measure is necessary to retain each tree. Prior to the beginning of construction a meeting between a certified arborist and the necessary contractors will be held to determine the appropriate level of protection for each tree, in relation what work needs to be completed in the tree's vicinity. On site supervision by a certified arborist will be determined and supplied as necessary. .• 1.......... • • . •• : . i.i.•!.,•rj ••; . • . • .„.... . . • i.A•ii • A A : . • ..4.1 ...... . • I.:A. .• ••• • .A.•'' .., .... ,,••• A. i A•••E .r' i . . .• ...,11::. .,.....

TVFR owns the �' ) P Prh' � g g ( )• Walnut Street site and is planning to build a new facility. This wetland delineation has been performed in compliance with accepted standards for professional wetland biologists and applicable federal, state, and local ordinances. The wetland boundaries described in this report represent PBS's best professional judgment based on the circumstances and site conditions encountered at the time of this study. The final determination of the wetland boundary and required setback and buffer will be made by local, state, and federal jurisdictions. 2.0 SITE DESCRIPTION 2.1 Project Location The property is in Tigard, Oregon, approximately 3 miles west of Interstate 5 (Figure 1). The 3.28-acre property, Tax Parcel 2S104AD04500, is in Section 4, Township 2S, Range 1W, W. M. (Figure 2). The approximate center of the property is at latitude 45° 25' 41" N and longitude 122° 48' 24" W. The property is in the Kreuger Creek subwatershed of the Fanno Creek subwatershed of the Tualatin River. 2.2 Site Description The property currently contains a home, barn, and outbuildings. The southeast portion of the Z. property is relatively flat. The site slopes down to the northwest to the bank of Kreuger Creek. Kreuger Creek flows northeast along the property boundary and has a flat flood plain of varying width adjacent to it. Jack Park is across the creek on the adjacent property. The entire property was investigated for the presence of waters and wetlands (Figures 2 and 5). The vegetation in the upper portion of the property around the existing home site consists of regularly mowed lawn and ornamental trees and shrubs. The slope is gentler on the northeast end of the property and the mowed area extends nearly to banks of the stream. The slope is steeper to the southwest and is not mowed. The slope is mostly vegetated with non-native lJ grasses including reed canarygrass (Phalaris arundinacea), orchard grass (Dactylis glomerata), tall fescue (Festuca arundinacea), common velvet grass (Holcus lanatus), _1 bluegrass (Poa sp.), and bentgrass (Agrostis sp.). Reed canarygrass is dominant in the floodplain. The slopes adjacent to both sides of the creek in the southwest portion of the ;, property were recently planted with native trees and shrubs. This area includes bigleaf maple (Ater macrophyllum), grand fir (Abies grandis), Douglas-fir (Pseudotsuga menziesii), red- twig dogwood(Cornus sericea), currant(Ribes sp.),tall Oregon grape (Berberis aquifolium), snowberry (Symphoricarpos albus), thimbleberry (Rubus parviflorus), and western sword Ifern (Polystichum munitum). The creek has scattered individuals and patches of young red alder(Alnus rubra) along its margin. These are generally less than 30 feet tall and 5 inches in diameter. • i . i Report Date:April 2007 PBS 1 - Project No.75020.000 • Wetland Delineation Report Tualatin y Fire and Rescue,Walnut Street Site Washington County,Oregon The Washington County Soil Survey shows two soil map units on the subject property, Delena silt loam, 3 to 12 percent slopes, and Cornelius and Kinton silt foams, 7 to 12 percent (• slopes (Figure 4). Delena silt loam is classified as a hydric soil (MRCS. 2006). Delena silt loam is a poorly drained soil found in gently to moderately sloping, concave swales and draws. It formed in mixed alluvium and eolian material on uplands. The surface layer is typically dark grayish-brown (10YR 3/2) silt loam about 16 inches thick. The lower six inches of that layer has few, fine, distinct yellowish brown (10YR 5/4) redoximorphic (redox) concentrations. This is underlain by 5 to 10 inches of dark grayish-brown(10YR 4/2) silty clay loam with many fine, prominent, reddish-brown (5YR 4/4) redox concentrations (Green 1982). , The Cornelius and Kinton silt loam consists of approximately 50 to 65 percent Cornelius soils and 25 to 35 percent Kinton soils. The Cornelius series consists of moderately well drained soils formed in loess-like material over fine-silty alluvium on uplands. A typical 1 profile consists of a surface layer of dark brown silt loam (10YR 3/3) about 6 inches thick. This is underlain by approximately 32 inches of brown (10YR 4/3) silt loam. The Kinton series consists of moderately well drained soils that formed in silty material over fine-silty, old alluvium of mixed origin on uplands. The typical profile consists of a 1-inch layer of decaying needles, twigs and leaves underlain by a 3-inch layer of very dark brown (10YR 3/2) silt loam. This is underlain by a 7-inch layer of dark yellowish-brown (1OYR 3/4) silt loam. The B horizon consists of approximately 20 inches of brown (10YR 4/3) silt loam (Green 1982). 1 2.3 Delineated Wetland t• PBS delineated one wetland immediately southeast of Kreuger Creek covering 0.22 acres (9,482 square feet) (Figure 5). It is a palustrine emergent wetland with a hydrogeomorphic class of Slope Valley(SV). This wetland continues offsite north of the property. 2.3.1 Plant Community The plant community consists almost entirely of herbaceous vegetation, except for the recently planted area at the southwest end and the scattered red alder along the creek. The herbaceous community is dominated by reed canarygrass, bentgrass, tall fescue ..„ (Festuca arundinacea), creeping buttercup (Ranunculus repens), and small-fruited bulrush(Scirpus microcarpus). ,� 2.3.2 Soils All data plots were within the Delena silt loam map unit. The soils generally did not I match the described profile. The observed soils were darker gray,had significant clay content, and had brighter, redder redox concentrations. The matrix color was typically gray to dark gray (10YR 4/1 and 5/1), although one plot had a dark grayish brown (10YR 4/2) matrix. Redox concentrations were common, fine to medium in size, . prominent, and were typically dark reddish brown to yellowish red(5YR 3/4 and 4/6) in color. . j •, lReport Date:April 2007 PBS 2 Project No.75020.000 1 Wetland Delineation Report Tualatin Vail moire and Rescue,Walnut Street Site Washington County,Oregon 2.3.3 Hydrology • The wetland lies on the floodplain adjacent to the creek, but the principle hydrologic source is the seepage of water at the toe of the adjacent slope. The stream is currently downcut 2-4 feet from the banks, and thus it would take a large storm for the creek to spill over its banks. This does not appear to be a common event currently although it may have been in the past before the downcutting occurred. Water leaves the wetland via infiltration and lateral subsurface flow into the creek. The hydrology is supplemented by precipitation falling onsite, which is retained by the poorly drained soils with a relatively flat topography. Po gra h pY• 2.3.4 Adjacent Upland,Wetland Boundary, and Rationale for Delineation Most of the wetland perimeter is characterized by a relatively abrupt change in topography. The wetland boundary was consistently at the base of the slope. The . plant community often did not change abruptly at the boundary. Reed canarygrass often extended a short distance beyond the boundary. Tall fescue and bentgrass were found on both sides of the line, while orchard grass (Dactylis glomerata) and rough cat's ear (Hypochaeris radicata) were only in the upland and hairy willow-herb . (Epilobium ciliatum) and small-fruited bulrush were only found in the wetland. Soils and hydrology did change sharply along the wetland boundary. Soil matrix colors . , ranged from very dark grayish brown (10YR 3/2) to dark grayish brown (10YR 4/2) . to brown (10YR 4/3). The upland soils contained no redox concentrations. Saturation was entirely lacking in all but one of the upland plots. ; 0 2.4 Site Alterations Pertaining to Waters and Wetlands The streambed is down cut 2 to 4 feet from the adjacent banks. This may have occurred due to heavy livestock traffic in and around the creek. The effect is most likely an earlier draw down in the water table adjacent to the creek in the spring and a later rise in the water table in the fall. The creek also has less opportunity to spill its banks during storm events and thus _1 less opportunity for the adjacent wetlands to slow and filter water and collect sediment. 3.0 METHODS j The entire property at Tax Parcel 2S104AD04500 was examined for wetlands and waters of the state. Wetlands were delineated using the Routine Determination Method for delineating wetlands described in the US Army Corps of Engineers Wetlands Delineation Manual (Environmental 1 Laboratory 1987). Preliminary preparation prior to the on-site investigation consisted of collecting and reviewing existing data and information that included the following: l • Local wetland inventory map • Washington County soil survey and hydric soils list • Washington County tax lot information • Aerial photographs I Report Date:April 2007 • PBS 3 Project No.75020.000 I • Wetland Delineation Report Tualatin Fire and Rescue,Walnut Street Site We p y Washington County,Oregon Data were recorded for 10 sample plots. Sample plots were established until paired samples (one wetland and one non-wetland) were obtained to accurately determine the location of the wetland 1 • boundary. Plot locations were chosen to best represent the wetland and the adjacent upland. Many of the plot locations were informed by anecdotal soil pits,which identified the perimeter of the area with saturation in the upper 12 inches of the soil. Photographs were taken to document site conditions (Figure 5, Appendix B). The ordinary high water mark (OHWM) of the creek and the wetland boundary were marked in the field using pink wire flags. Sample plots were marked with yellow wire flags. The OHWM flags were labeled with sequential numbers going from the southwest to the northeast. Wetland boundary flags were labeled with the letter "W" (for wetland) followed by sequential numbers going from the southwest to the northeast (i.e., W 1, W2, and so on). Sample plots were labeled with SP (an abbreviation for sample plot) and a sequential number(i.e., SP-1, SP-2 and so on). 3.1 Soils Soil profile holes were dug to assess the soil characteristics and the presence of subsurface hydrology. Soil colors, texture, and presence of redoximorphic features were recorded,and hydric soils were determined using the indicators described in the 1987 Manual.Munsell Soil Color Charts (Munsell Color 2000) was used to determine the color of the soil matrix and "� redox features. The sample point locations were selected to best characterize the conditions at the site. 3.2 Hydrology Visible observations of surface and subsurface hydrology were noted on the data sheets and {10 the depth to saturated soils and free water were recorded at each sample point. 3.3 Vegetation Vegetation was characterized for the upland and wetland areas and recorded at each sample point. Visual estimates were made of percent cover of each species occurring within a sample plot. Excepting the planted area, all sample plots contained only one vegetation stratum, the herbaceous layer. Cover of each herbaceous species was estimated within a 5-foot radius of each sample point. Dominant species were determined using the 50/20 rule. Dominant plant species for each `Ii stratum are those that cumulatively make up the most abundant 50 percent, plus any additional species with 20 percent or more cover. The wetland indicator status for each dominant plant species was used to determine the presence or absence of a wetland 1 (hydrophytic) plant community based on the wetland plant list for Region 9 (Reed 1988, Reed 1993). The indicator status describes how likely a species is to be found in wetlands (Appendix C). . _1 J . .1 -- Report Date:April 2007 p B S 4 Project No.75020.000 Wetland Delineation Report Tualatin Va ire and Rescue,Walnut Street Site • Washington County,Oregon 4.0 COMPARISON TO EXISTING WETLAND INVENTORY IIThe Local Wetland Inventory (LWI) and Washington County GIS data show the wetland and the creek northwest of the property,but the delineation verified that the creek actually straddles the property line near the southwest corner,but otherwise is completely on the subject property. The stream contains wetlands on its northwest as well as its southeast sides,but only the wetland boundary southeast of the creek were delineated in this study. 5.0 MAPPING METHOD The sample plot locations and wetland boundaries were mapped using a Trimble GeoXT GPS receiver. Following post-processing (differential corrections) of data collected in the field, this instrument produces mapping data accurate within one meter. 6.0 FIELD WORK Jason Clark conducted fieldwork on February 21, 2007. This included collection of sample plot data, general site observations and documentation, flagging of the wetland boundary, mapping of the site, and taking photographs. Doug Swanson, PWS, reviewed the field delineation and verified the wetland boundaries on April 17, 2007. 7.0 CLIMATE AND RECENT PRECIPITATION _1 Washington County has a predominantly temperate marine climate typical of much of the west coast. Summers are warm and relatively dry, and winters tend to be mild, but rather wet. The coastal •1 mountains protect the county from the intense winter storms common on the coast. Mean high �j • temperatures for Beaverton, Oregon, range from 46.4°F in December to 79.7°F in August. Mean low temperatures range from 33.4°F in January to 53.7°F in July. Precipitation levels are considered normal when they fall between figures for which there is a 30% chance of more than that amount and a 30% chance of less than that amount (Table 1). For the month of January, the area received less rainfall than average, and was below the normal range. In January, rainfall was 3.45 inches `1 below the average of 6.19 inches. On February 21 (the day of the first field visit), rainfall was 1.07 inches below the average month to date amount. The percent of average rainfall for the water year beginning October 1, 2006 was 107% on February 21, 2007. Daily precipitation totals for the 10 days prior to the day of fieldwork are listed in Table 2. l J I .

The ordinary high water mark of Kreuger Creek was delineated along its southeast bank. One wetland totaling 0.22 acres _: (9,482 square feet) was delineated adjacent to the southeast bank of Kreuger Creek (Figure 5). The wetland boundary is based on the presence of wetland plant communities, wetland soils, and observed hydrology within the wetland, and conditions in adjacent areas lacking indicators of one or more of the wetland criteria. • 8.2 Growing Season lThe Natural Resources Conservation Service (NRCS) defines the growing season as that portion of the year when soil temperatures at 20 inches below the soil surface are equal to or greater than biological zero (41°F or 5°C). The soil temperature 20 inches below the surface on February 21, 2007 was 45°F, as measured by a 24-inch Ashcroft soil thermometer. Therefore,the field visit occurred during the growing season. _I . 1 ____ _ Report Date:April 2007 t PBS Project No.75020.000 6 t Wetland Delineation Report • Tualatin Val•re and Rescue,Walnut Street Site Washington County,Oregon • 8.3 Regulatory Context Wetlands and streams that are tributary to navigable waters are regulated as "Waters of the United States" by the US Army Corps of Engineers under § 404 of the Clean Water Act and by the Oregon Department of State Lands (DSL)for the purposes of the Removal-Fill Law as "waters of the state" (OAR 141-090-0005 to 0055).

After reviewing the plans,we are prepared to approve the plans,provided some concerns are addressed. The plans seem to allow for good access to the enclosure, and provide adequate space for the truck to operate safely. However, it is not clear whether the spaces immediately across from the • enclosure are pull-out spaces for the fire trucks, or are parking spaces for use by vehicles.Also,the distance between those spaces &the enclosure is not noted. Please be aware our trucks need at least 75' of unobstructed access to the containers. The only other note we have is with the design of the gates on the enclosure. It appears there are to be of a `bi-fold' construction. We are concerned that this may not allow them to be secured properly to avoid property and personal damage should the gates swing due to wind or impact. We recommend 10' gates with cane bolt lock-backs in the open position, as well as closed. Overall, we are satisfied with the placement of the enclosure, ease of access, and proposed size. Having taken this into account, we are sending this letter as an official approval from our company, with the understanding that the above mentioned concerns will be noted. If you have any additional questions, feel free to contact us.

TVFR contracted with PBS Engineering and Environmental (PBS) to prepare a Natural Resources Assessment Report (NRA) for the subject property, to comply with the surface,water management requirements of Clean Water Services(CWS). The Natural Resources Assessment Report is an evaluation of Water Quality Sensitive Areas, Vegetated Corridors, and steep slopes in the project area. Sensitive areas include: 1) existing and created wetlands, 2) perennial or intermittent rivers, streams, and springs, and 3) natural lakes, ponds, and in-stream impoundments. CWS has established design and construction standards, which when used in combination with other state, federal, and local laws and ordinances, are intended to protect the beneficial uses of waters within the Tualatin River Basin. 1.1 Regulatory Overview Clean Water Services requires that a Service Provider Letter be secured by the applicant before approval of development activities within 200 feet of water quality sensitive areas. The Service Provider Letter specifies the conditions and requirements associated with sensitive areas and vegetated corridors (the buffers around sensitive areas). The standards, requirements, and methods for sensitive area site assessments are contained in Chapter 3 and Appendix C of the Design and Construction Standards for Sanitary Sewer and Surface Water Management(CWS 2004). 1.2 Project Location The property is in Tigard, Oregon, approximately 3 miles west of Interstate 5 (Figure 1). The (. 3.28-acre property, Tax Parcel 2S104AD04500, is in Section 4, Township 2S, Range 1W, W. M. The approximate center of the property is at latitude 45° 25' 41"N and longitude 122° 48' 24" W. The property is in the Kreuger Creek subwatershed of the Fanno Creek subwatershed of the Tualatin River. 1.3 Project Description TVFR is planning to build a new facility on the site. The facility will include a fire station, a community meeting room,two parking lots, and two driveways(Figure 2): 1.4 Assessment Area Clean Water Services requires an assessment of the property proposed for development and undeveloped areas within 200 feet of the project site. The property currently contains a home, barn, and outbuildings. The southeast portion of the property is relatively flat. The site slopes down to the northwest to the bank of Kreuger Creek. Kreuger Creek flows northeast along the property boundary and has a flat floodplain of varying width adjacent to it (Figure 2). Jack Park is across the creek on the adjacent property. Vegetation lines the Kreuger Creek corridor along the northwestern property boundary. The property is zoned single-family residential and is surrounded by other residential properties with the exception of Jack Park to the north. • Report Date:April 2007 PBS 1 Project No.75020.000 • Natural Resources Assessment Report Tualatin Valley Fire and Rescue,Walnut Street Site Washington county.Oregon • 2.0 METHODS The natural resources assessment consists.of three major tasks: identifying the sensitive areas, determining vegetated corridor widths, and determining the condition of the vegetated corridors surrounding the sensitive areas. The initial phase of the assessment involved the acquisition and review of existing information pertaining to the site.Information was obtained from the following resources: • Soil Survey of Washington County,Oregon(Green 1982)` , • Aerial photographs • USGS topographic map,Beaverton,Oregon 7.5-minute quadrangle • Local Wetland Inventory • National.Wetland Inventory • . • - Metro Data Resource Center's MetroMap These resources were reviewed and used with field observations to identify water quality sensitive areas on or within 200 feet of the project site. PBS biologists conducted fieldwork on February 21, 2007. 2.1 Identification of Sensitive Areas All water quality sensitive areas on the project site and within the 200-foot assessment area were identified and their limits were determined using the methods in Appendix C of the Design and Construction Standards (CWS 2004). This included the delineation of the • ordinary high water mark of Kreuger Creek and delineation of the boundaries of the adjacent wetland. 2.2 Evaluation of Vegetated Corridors The condition s, standards, and procedures used in the site assessment are described in Section 3.02, Sensitive Area and Vegetated Corridor Standards, and in Appendix C: Natural Resource Assessments in the Design and Construction Standards (CWS 2004). Vegetated corridor widths for the water quality sensitive areas were determined following methods and criteria presented in section 3.02.4 of the Design and Construction Standards(Table 1). • Report Date:April 2007 PBS Project No.75020.000 2 • • Natural Resources Assessment Report Tualatin Valley Fire and Rescue,Walnut Street Site Washington County,Oregon Table 1.Vegetated Corridor Width Criteria.

PBS biologists gathered composition and cover data at sample plots approximately 120 feet apart on the southeast side of Kreuger Creek. Vegetation was sampled for all species with cover greater than five percent using a 30-foot radius plot for woody vegetation and a 10-foot radius plot for herbaceous vegetation.The condition of each plant community was rated as good, marginal, (111 or degraded based on cover by native species and tree canopy cover(Table 2).

Kreuger Creek flows northeast along the northwest property line. It enters the property through a concrete box culvert underneath SW Walnut Street and flows offsite across the northern property boundary. A wetland was delineated in the floodplain of the creek along its southeastern bank. The palustrine emergent wetland covers 9,482 square feet and has a hydrogeomorphic (HGM) subclass of Slope Valley(SV).The wetland extends north onto the adjacent property. Report Date:April 2007 PBS 3 Project No.75020.000 • Natural Resources Assessment Report• Tualatin Val ey Fire and Rescue,Walnut Street Site Washington County.Oregon • The creek and adjacent wetland are the only water quality sensitive areas that occur within the assessment area. The wetland was delineated using methods in the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987). The delineation report is included in Appendix A. 3.2 Vegetated Corridor The vegetated corridor was evaluated for the portion of Kreuger Creek that flows through the subject property (Figures 2 and 3). Vegetated corridor width was determined, in accordance with section 3.02.4 of the Design and Construction Standards, following assessment of the slope of the land adjacent to the creek and wetland. The calculated corridor width for wetlands less than 0.5 acres is 25 feet,but because the wetland is along a perennial creek,the streamside corridor exceeds that distance (Table 1). The northeast half of the corridor contains slopes that are less than 25% resulting in a corridor width of 50 feet. The southwest half of the corridor contains slopes that are greater than 25%. In this area, the calculated width of the corridor was determined by adding a 35-foot buffer to the observable slope break. This results in a corridor width of 55 to 75 feet. (Figure 2). Two plant communities make up the vegetated corridor within the assessment area. The vegetation data is represented in Table 3. Photographs are included with the wetland delineation in Appendix A. 3.2.1 On-site Vegetated Corridor Plant Community 2 includes plots VC-2 through VC-6 and spans the entire on-site corridor. This plant community is dominated by non-native grasses including bentgrass (Agrostis sp.), tall fescue (Festuca arundinacea), bluegrass (Poa sp.), and • orchardgrass (Dactylis glomerata). Reed canarygrass (Phalaris arundinacea) and common horsetail (Equisetum arvense) are also present adjacent to the wetland. This area has very little shrub or tree cover. The average covers of trees (3%) and native species (9%) meet the criteria for a corridor in "Degraded" condition. Most of the area is regularly mowed. 3.2.2 Off-site Vegetated Corridor Plant community 1 is represented by plot VC-1 and is located 40 feet north of the property line. This community begins at the property line and continues northeast along the southeast bank of the creek. This plant community has high cover of trees (105%) and native species (90%). Therefore, this community meets the criteria for a corridor in "Good" condition. The site is dominated by native species including Douglas-fir (Pseudotsuga menziesii), red alder (Alnus rubra), and Pacific crabapple (Malus fusca). Non-native trees and shrubs are also present including English holly (Ilex aquifolium), English laurel (Prunus laurocerasus), Portugal laurel (Prunus lusitanica),English ivy(Hedera helix),and Himalayan blackberry(Rubus discolor). • Report Date:April 2007 PBS a Project No.75020.000 • • Natural Resources Assessment Report Tualatin Valley Fire and Rescue,Walnut Street Site Washington County.Oregon Table 3.Vegetated Corridor Plot Data and Condition Ratings for the Tualatin Valley Fire and ( • Rescue Assessment Area—Tax Lot 2S104AD04500. vii- 4,4,�. ;Y? ,.--" Wag. r—� "f�� rt A eLCeareeVeT 1. 4 g . � �s _ tom-mot< .�4WAP r . a _' Invasive* �VG : M ,r. , •lnus rubra N 30 -... 15 . lex a,ui olium 15 alus usca N 20 'nmus laurocerasus 10 " ` 'runus lusitanica 20 'seudotsu•a menziesii N 40 --- ahonia a,ui olium N 10 edera helix I 10 'ubus discolor I 6 - •_ ostis s,. 73 .. 82 62 .... . . . 85 ac /is;lomerata --- 25 uisetum arvense N --_- 15 estuca anmdinacea 15 12 7 10 30 sochaeris radicata -- 6 6 6 6 'oa s,. 30 'ol stichum munitum N --_- 6 n olium s,. -- 6 ,,,,,,.,,,,„4,, r,„,„:. .- ; � ,"" g ¢' any ^� „ii,-..-.

Tualatin Valley Fire and Rescue (TVFR) contracted with PBS,Engineering and Environmental (PBS) to delineate wetlands on a property'in Tigard, Oregon (Walnut Street Site). TVFR owns the Walnut Street site and is planning to build a new facility. This wetland delineation has been -performed in compliance with,accepted standards for professional wetland biologists and applicable federal,'state, and local ordinances. The wetland boundaries described in this report represent PBS's best professional judgment based on the circumstances and site conditions encountered at the time of this study. The final determination of the wetland boundary and required setback and buffer will be "made by local,state,and federal jurisdictions. 2.0 SITE DESCRIPTION 2.1 . Project Location The property is in Tigard, Oregon, approximately 3 miles west of Interstate 5 (Figure 1). The 3.28-acre property, Tax Parcel 2S104AD04500, is in Section 4, Township 2S, Range 1W, W. M. (Figure 2). The approximate center of the property is at latitude 45° 25' 41" N and longitude 122°48'.24" W. The prop_ erty is in the-Kreuger Creek subwatershed of the Fanno Creek subwatershed of the Tualatin River. 2.2 Site Description The property currently contains a home, barn, and outbuildings. The southeast portion of the property is relatively flat. The site slopes down to the northwest to the bank of Kreuger Creek. Kreuger Creek flows northeast along the property boundary and has a flat flood plain of varying width adjacent to it. Jack Park is across the creek on the adjacent property. The • entire property was investigated for the presence of waters and wetlands(Figures 2 and 5). The vegetation in the upper portion of the property around the existing home site consists of regularly mowed lawn and ornamental trees and shrubs. The slope is'gentler on the northeast end of the property and the mowed area extends nearly to banks of the stream. The slope is steeper to the southwest and is not mowed. The slope is mostly vegetated with non-native grasses including .reed canarygrass (Phalaris arundinacea), orchard grass (Dactylis glomerata), tall fescue (Festuca arundinacea), common velvet grass (Holcus lanatus), bluegrass (Poa sp.), and bentgrass .(Agrostis sp.). Reed canarygrass is dominant in the floodplain. The slopes adjacent to both sides of the creek in the southwest portion of the property were recently planted with native trees and shrubs. This area includes bigleaf maple (Acer macrophyllum), grand fir (Abies grandis), Douglas-fir (Pseudotsuga menziesii), red- twig dogwood(Cornus sericea), currant(Ribes sp.), tall Oregon grape(Berberis aquifolium), snowberry (Symphoricarpos albus), thimbleberry (Rubus pary onus), and western sword fern (Polystichum munitum). The creek has scattered individuals and patches of young red alder(Alnus rubra) along its margin.These are generally less than 30 feet tall and 5 inches in diameter. • Report Date:April 2007 PBS Project No.75020.000 • i • Wetland Delineation Report Tualatin Valley Fire and Rescue,Walnut Street Site • Washington County,Oregon The Washington County Soil Survey shows two soil map units on the subject property, ( • Delena silt loam, 3 to 12 percent slopes, and Cornelius and Kinton silt loams, 7 to.12 percent .slopes (Figure 4). Delena silt loam is classified.as a hydric soil(MRCS 2006). Delena. silt loam is a poorly drained soil found in gently to moderately sloping , concave swales:and draws. It formed in 'mixed alluvium and eolian material on uplands. The surface layer is typically.dark:grayish-brown (10YR 3/2) silt loam.about 16 inches thick. The lower six inches of that layer has few, fine, distinct yellowish brown (10YR 5/4) redoximorphic (redo x)concentrations. This is underlain by 5 to 10 inches of dark grayish-brown(1 OYR 4/2) silty clay loam with many fine, prominent, reddish-brown (5YR 4/4)'redox concentrations (Green 1982). The Cornelius and Kinton silt loam consists of approximately 50 to 65 percent Cornelius soils and 25 to 35 percent Kinton soils. The Cornelius series consists of moderately well drained soils formed in loess-like material over fine-silty alluvium on uplands. A typical profile consists of a surface layer of dark brown silt loam (10YR 3/3) about 6 inches thick. This is underlain by approximately 32 inches of brown(10YR 4/3) silt loam. The Kinton series consists of moderately well drained soils that formed in silty material over fine-silty, old alluvium of mixed origin on uplands. The typical profile consists of a 1-inch layer of decaying needles, twigs and leaves underlain by a 3-inch layer of very dark brown (10YR 3/2) silt loam. This is underlain by a 7-inch layer of dark yellowish-brown (10YR 3/4) silt loam. The B horizon consists of approximately_ 20 inches of brown (10YR 4/3) silt loam (Green 1982). 2.3 Delineated Wetland 11) PBS delineated one wetland immediately southeast of Kreuger Creek covering 0.22 acres (9,482 square feet) (Figure 5). It is a palustrine emergent wetland with a hydrogeomorphic class of Slope Valley(SV). This wetland continues offsite north of the property. 2.3.1 Plant Community The plant community consists almost entirely of herbaceous vegetation, except for the recently planted area at the southwest end and the scattered red alder along the creek. The herbaceous community is dominated by reed canarygrass, bentgrass, tall fescue (Festuca arundinacea), creeping buttercup (Ranunculus repens), and small-fruited bulrush(Scirpus microcarpus). 23.2 Soils All data plots were within the Delena silt loam map unit. The soils generally did not match the described profile. The observed soils were darker gray,had significant clay content,and had brighter,redder redox concentrations. The matrix color was typically gray to dark gray (10YR 4/1 and 5/1), although one plot had a dark grayish brown (10YR 4/2) matrix. Redox concentrations were common, fine to medium in size, prominent, and were typically dark reddish brown to yellowish red(5YR 3/4 and 4/6) in color. Report Date:April 2007 PBS 2 Project No.75020.000 • • Wetland Delineation Report Tualatin Valley Fire and Rescue,Walnut Street Site Washington County,Oregon • 2.3.3 Hydrology The wetland lies on the floodplain adjacent to the creek, but the principle hydrologic source is the seepage of water at the toe of the adjacent slope.'The stream is currently • • downcut 2-4 feet from the banks, and thus it would take a large storm for the creek to spill over its banks: This does not appear to be a common event currently although it may have been in the past before the downcutting occurred. Water leaves the wetland • via infiltration and lateral subsurface flow into the creek. The hydrology is supplemented by precipitation falling onsite, which is retained by the poorly drained soils with a relatively flat topography. 2.3.4 Adjacent Upland,Wetland Boundary,and Rationale for Delineation Most of the wetland perimeter is characterized by a relatively abrupt change in topography. The wetland boundary was consistently at the base of the slope. The plant community often did not change abruptly at the boundary. Reed canarygrass often extended a short distance beyond the boundary. Tall fescue and bentgrass were found on both sides of the line, while orchard grass (Dactylic glomerata) and rough • cat's ear (Hypochaeris radicata) were only in the upland and hairy willow-herb (Epilobium ciliatum) and small-fruited bulrush were only found in the wetland. Soils and hydrology did change sharply along the wetland boundary. Soil matrix colors ranged from very dark grayish brown (10YR 3/2) to dark grayish brown (10YR 4/2) to brown(10YR 4/3). The upland soils contained no redox concentrations. Saturation was entirely lacking in all but one of the upland plots. • 2.4 Site Alterations Pertaining to Waters and Wetlands The streambed is down cut 2 to 4 feet from the adjacent banks. This may have occurred due to heavy livestock traffic in and around the creek. The effect is most likely an earlier draw down in the water table adjacent to the creek in the spring and a later rise in the water table in the fall. The creek also has less opportunity to spill its banks during storm events and thus less opportunity for the adjacent wetlands to slow and filter water and collect sediment. 3.0 METHODS The entire property at Tax Parcel 2S104AD04500 was examined for wetlands and waters of the state. Wetlands were delineated using the Routine Determination Method for delineating wetlands described in the US Army Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987). Preliminary preparation prior to the on-site investigation consisted of collecting and reviewing existing data and information that included the following: • Local wetland inventory map • Washington County soil survey and hydric soils list • Washington County tax lot information • Aerial photographs Akr Report Date:April 2007 PBS 3 Project No.75020.000 • • Wetland Delineation Report Tualatin Valley Fire and Rescue,Walnut Street Site Washington County,Oregon Data were recorded for 10 sample plots. Sample plots were established until paired samples(one (• wetland and one non-wetland)were obtained to accurately determine the location of the wetland boundary.Plot locations were chosen to best represent the wetland and the adjacent upland. Many of the plot locations were informed by anecdotal soil pits,which identified the perimeter of the area with saturation in the upper 12 inches of the soil. Photographs were taken to document site conditions (Figure 5, Appendix B). The ordinary high water mark (OHWM) of the creek and the wetland boundary were marked in the field using pink wire flags. Sample plots were marked with yellow wire flags. The OHWM flags were labeled with sequential numbers going from the southwest to the northeast. Wetland boundary flags were labeled with the letter "W" (for wetland) followed by sequential numbers going from the southwest to the northeast(i.e., W1, W2, and so on). Sample plots were labeled with SP (an abbreviation for sample plot)and a sequential number(i.e., SP-1, SP-2 and so on). 3.1 Soils Soil profile holes were dug to assess the soil characteristics and the presence of subsurface hydrology. Soil colors, texture, and presence of redoximorphic features were recorded, and hydric soils were determined using the indicators described in the 1987 Manual. Munsell Soil Color Charts (Munsell Color 2000) was used to determine the color of the soil matrix and redox features. The sample point locations were selected to best characterize the conditions at the site. 3.2 Hydrology - Visible observations of surface and subsurface hydrology were noted on the data sheets and (• the depth to saturated soils and free water were recorded at each sample point. 3.3 Vegetation Vegetation was characterized for the upland and wetland areas and recorded at each sample point. Visual estimates were made of percent cover of each species occurring within a sample plot. Excepting the planted area, all sample plots contained only one vegetation stratum, the herbaceous layer. Cover of each herbaceous species was estimated within a 5-foot radius of each sample point. Dominant species were determined using the 50/20 rule. Dominant plant species for each stratum are those that cumulatively make up the most abundant 50 percent, plus any additional species with 20 percent or more cover. The wetland indicator status for each dominant plant species was used to determine the presence or absence of a wetland (hydrophytic) plant community based on the wetland plant list for Region 9 (Reed 1988, Reed 1993). The indicator status describes how likely a species is to be found in wetlands (Appendix C). • Report Date:April 2007 PBS 4 Project No.75020.000 • Wetland Delineation Report • Tualatin Valley Fire and Rescue,Walnut Street Site • Washington County,Oregon • 4.0 COMPARISON TO EXISTING WETLAND.INVENTORY • The Local Wetland Inventory(LWI)"and Washington County GIS_data show the wetland and the creek northwest of the property,but the delineation verified that the creek actually straddles the property line near the southwest corner,but otherwise is completely on the subject property. The stream contains wetlands on its northwest as well as its southeast sides,but only the wetland boundary southeast of the creek were delineated in this study. 5.0 MAPPING METHOD .The sample plot locations and wetland boundaries were mapped using a Trimble GeoXT GPS receiver. Following post-processing (differential corrections) of data collected in the field, this instrument produces mapping data accurate within one meter. 6.0 FIELD WORK Jason Clark conducted fieldwork on February 21, 2007. This included collection of sample plot data, general site observations and documentation, flagging of the wetland boundary, mapping of the site, and taking photographs. Doug Swanson, PWS, reviewed the field delineation and verified the wetland boundaries on April 17,2007. 7.0 CLIMATE AND RECENT PRECIPITATION • Washington County has a predominantly temperate marine climate typical of much of the west coast. Summers are warm and relatively dry, and winters tend to be mild,but rather wet. The coastal mountains protect the county from the intense winter storms common on the coast. Mean high • temperatures for Beaverton, Oregon,range from 46.4°F in December to 79.7°F in August. Mean low temperatures range from 33.4°F in January to 53.7°F in July. Precipitation levels are considered normal when they fall between figures for which there is a 30%chance of more than that amount and a 30% chance of less than that amount (Table 1).•For the month of January, the area received less rainfall than average, and was below the normal range. In January, rainfall was 3.45 inches below the average of 6.19 inches. On February 21 (the day of the first field visit), rainfall was 1.07 inches below the average month,to date amount. The percent of average rainfall for the water year beginning October 1, 2006 was 107% on February 2007.

The ordinary high water mark of Kreuger Creek was delineated along its southeast bank. One wetland totaling 0.22 acres (9,482 square feet) was delineated adjacent to the southeast bank of Kreuger Creek (Figure 5). The wetland boundary is based on the presence of wetland plant communities, wetland soils, and observed hydrology within the wetland, and conditions in adjacent areas lacking indicators of one or more of the wetland criteria. 8.2 Growing Season The Natural Resources Conservation Service (NRCS) defines the growing season as that portion of the year when soil temperatures at 20 inches below the soil surface are equal to or greater than biological zero (41°F or 5°C). The soil temperature 20 inches below the surface on February 21, 2007 was 45°F, as measured by a 24-inch Ashcroft soil thermometer. Therefore,the field visit occurred during the growing season.

The Corps of Engineers regulates fill in and discharges to waters of the U.S. DSL regulates both fill and excavation in waters of the state. Clean Water Services, a public wastewater, stormwater,and surface water management utility serving parts of the Tualatin River watershed, regulates areas adjacent to Water .. . Quality •Sensitive Areas (wetlands,-lakes,:streams,`;and seeps) as Vegetated Corridors. Vegetated Corridors act as buffers between sensitive areas and adjacent development. 9.0 DISCLAIMER This report documents 'the investigation,'best professional judgment and conclusions of PBS Engineering and Environmental.-It is'correct and complete to the best of our knowledge. It should be considered a Preliminary Jurisdictional Determination of wetlands and other waters and used at your own risk until•it has been'reviewed'and approved in writing by the Oregon Department of State Lands in accordance with OAR 141-090-0005 through 141-090-0055.
