Recently areas of the mountain (specifically Bull Mountain Summit View Estates and the acreage known as the Zednick property) have been, or are in the process of being, annexed by the city of Tigard. Plans to develop the 40 acres furthest north (at the bottom of Bull Mt.) are now being submitted to you, and within a st*ort time, the rest of the development plans for the remaining acreage will also be submiLted. The whole area includes ravines, steep hillsides, streams and old forests as well as buildable acreage. According to the Washington County Bull Mountain Community Plan, this entire area is considered a Significant Natural Area, and as designated an Area of Special Concern (A.S.C. 3), indicating that additional study and planning by citizens and government agencies for protection as well as public and private use was necessary. This additional planning was never completed by the county, so now we have the opportunity to work with you in planning for the area. We believe that while much of this area can be successfully developed, it is also necessary to maintain as much as possible the natural landscape that draws people to Bull Mountain and gives this area its unique, high quality appeal. For that reason we are deeply concerned that the following issues be resolved before development actually begins: 1. That a way be found to preserve 50% of the mature trees, as specified in the Community Plan. We strongly urge that groups or blocks of trees be maintained, as opposed to leaving scattered trees around houses, to meet this requirement. This will prevent blow- down, keep the trees roots undamaged so they will remain healthy and p:zovide shelter for wildlife. It will also create buffer zones between the developments. To save viable stands of trees • it may b necessary to cluster the houses closer together, 2. That drainages and ravines become dedicated open areas, with no development allowed on them in the future, and that enough area be set aside to keep water quality from the waterways in these areas high. 3. Allow for access into these open areas/ so that in the future pedestrian paths could be built, as is currently being done with Three Mountain Estates a-id Benchviewb consider reqUiring linkage or a continuation of these plans into the neW development as well, 4. In respect to the 40 acre development plan before you, we are lalso y stub into place requesting a design change on the preliminary plan to p ale ravime� sac between lots 16 and 17 rather than n a road into this area in the future is completely Building inappropriate. 5.

Mr. Randy Wooley of the city engineering staff was present to answer questions. This proposal is scheduled for consideration at your February 20th meeting. A number of persons at the meeting expressed appreciation to the developer and his representatives, for their openness and cooperation during the planning process for this development The recomnrnendations of CPO4B, as approved by those attending this special meeting, are as follows: 1. We to commend acceptance of the street and traffic design as proposed. 2. We recommend that the city investigate concerns of storm runoff in ihp drainage on the west side of this property, through the tern Street Neighborhood. A number of persons expressed concern that the increase in runoff in this drainage, due to the houses and streets in the new development, will cause flooding on Fern Street and on the properties adjoining the stream which carries the drainage flow. 3, We request that the city of Tigard allow the membership of CP04B the opportunity to review and comment upon the engineering designs for all fsite i p developer, pri. pp for _ the n +Lf'Sate improvements conditioned upon this Ierecognize prior �the rneed l f th designs signs and construction of the improvements. e.�peditious handling of these designs, and we will cooperate to ensure the timely completion of this work. Your truly, Larry Westerman •,r4. r Nag 20 February 1990 Planning Commission City of Tigard 13125 SW Hail Blvd. Tigard OR 97223 To the Planning Commission: Last night, the neighbors in the area of SW 135th and SW Fern Street met to discuss the planned development by Taira-Klaus on Bull Mountain south of our neighborhood. The neighbors have asked me to speak on their behalf regarding this development. We would like to express our gratitude and appreciation to the developers and their representatives, for their openness and cooperation with our neighborhood during this planning process. We recognize that the developer has taken our comments seriously, and has made substantial changes in his design plan.; to accommodate our concerns. We are grateful for this effort. We believe that the planned development is well designed, and ask the Planning Commission to approve the site plans in their current form. During the planning process, the developers have been solicitous of people's concerns about improvements on SW 135th Street where it passes through our neighborhood. They have voluntarily stated that they intend to make significant improvements to this street in excess of what can be legally required of them. We applaud their willingness to contribute in this way to the quality of our neighborhood. The current and future status of SW 135th Street, south of SW Walnut, is of great concern to all of us in the neighborhood, and we would like to continue to work with the city and the builder to ensure that the improvements will result in a safe and convenient area for us to live. In this regard, we would like to make three specific recommendations to the Planning Commission regarding this section of SW 135th Street. First, we would strongly urge the city to agree to assume maintenance responsibility for this section of SW 135th after the construction improvements are completed. Inasmuch as the remainder of SW 135th Street, south of SW Scholls Ferry Road and continuing up to SW Bull Mountain Road, will be the property of the city of Tigard, it seems reasonable and sensible for this small section to become city property as well This will ensure that proper maintenance is performed. This is a particular concern to us in the neighborhood during inclement weather as we have seen during the past two weeks. This hill is very slippery, and will require ashes for traction under icing conditions. Since the city will have the responsibility for the rest of the street, acquisition of this short section from SW Walnut south to the new development will ensure continuity of coverage during such situations, , provide n arkim ®n ffeet of Secondly, on-street dly we recommend that the builder s` street with 3�` the opposite pavement, with a sidewalk on one side, and o side. We believe that this configuration best serves the needs of the neighborhood and the new development, in providing a neighborhood street fully capable of accommodating the traffic through the area, and providing safety for pedestrians using the street as well. Although there was some disagreement on the exact placement of the sidewalk, I believe that the concensus was that the sidewalk should be on the west side of the street. This will be safer for the children who walk ,down will to catch the school bus, and w im rove the site distance at the intersection stn and SW 135th. p tersectxon of SW Fe Thirdly, the members of the neighborhood are all aware of the dangerous conditions which exist at the intersection of SW Fern Street and SW 135th, In snowy or freezing conditions, this _ intersection becomes so slippery that traffic entering onto SW 135th from SW Fern cannot reliably stop to provided accommodate cross traffic. Therefore, we request that stop signs p at this intersection, on SW Fern 135th traveling east, and on SW of traveling ng north (down the hill). This will aid greatly imp rove the safety corner you We welcome this Thank ou very much for your. thoughtful consideration. improvement, opportunity to express our opinions and concerns about this im rovement, and pledge to work closely with the city and developer i d deyelo er as this construction P� proceeds.

Sack rq_ tand Information On July 17, 1989, the Tigard City Council approved a request for annexation of the subject property and forwarded Resolution Number 89- 57 to the Metropolitan Area Boundary Commnission for its consideration. The Boundary Commission approved the annexation on August 24, 1989 (Boundary Change Proposal No. 2663). On September 11, 1989, the City Council adopted a change in zoning of the m+ub ect property f rom Washington County R -6 to City of Tigard F--7 PD (Residential 7 unite per acre, planned development) The Urban Planning Area Agreement, between the City and Washington County, requires the City to adopt the zone which most closely resembles the existingWashington County zone ) STAFF REPORT - �c ®uZAx /BURTC�N (S 90- .�0�. %pD 90 -0�, Si� 9c� 0�, PAGE 1 for a period of at least one year. This change In zoning was consistent with the agreement. Both the Washington county R-6 and the City of Tigard R-7 zones allow for a 5,000 Square foot minimum lot size for single family residences. 3. VicinityDIEgontlen S.W. 135th Avenue extends from the northeast property corner directly north to S.W. Walnut Stmet. Along the property's northern border lie a number of home siten that generally range in size from one-half to two acres. These residences are located on either side of S.W. Fern Street, which runs east and west with an intersection with S.W. 135th Avenue at its east end. Large undeveloped properties lie tn the east, west, and south. Benchview subdivision lies to the southeast. This subdivision and the land to the east of the property are currently within the City of Tigard. The surrounding properties within Washington County are presently zoned R-6 and the parcels within the City of Tigard are zoned R-4.5 (Residential 4.5 units per acre). 4. Site Information Angpl:31,11_4131 The property to be developed is presently vacant and is situated on the lower portion of Bull Mountain's northern slope. The property is almost entirely wooded. A large ravine, which runs downhill to the north is located on the west side of the property and the remainder of the parcel slopes down to the northeast and emit. The applicant propoees to divide the property into 119 single family residential lots. Initially, access will only be provided by a southerly extension of 135th Avenue. This extension is intended to be a minor collector street. which will continue up the hill and eventually connect with S.W. Bull Mountain Road. Other local streets within the subdivision will provide access to the proposed lots as well as abutting properties to the south and west. The large westerly ravine will remain undeveloped at this point, however, the applicant has illustrated a conceptual street alignment which would extend across the ravine to the adjacent property to the west. A Sensitive Lands review is also necessary because of the installation of a sewer line along the eaet side of the western ravine And the possibility that other construction will occur on-slopes'in excess of 25 percent. The majority of the property has slopes leas than 25 percent, however it is possible that a limited amount of public facility and residential constructien Will occur on slores steeper than 25 percent. 5. Agency and NPO Comments The Engineering Division had the following comments: The applicant proposes to develop 39.2 acres of vacant land which has recently been annexed into the city. The land is located on the Northeast STAFF REPORT - kOUZAI/BURTON (S 90-01/PD 90-01/SL 90-01) PAGE 2 • 4 - its.! _ side of Bull Mountain and is relatively steep with one ravine with very steep side banks. No public facilities currently exist on the property. The applicant has submitted a site plan showing the proposal lot layout and public road, water, sanitary sewer, and storm drainage systems. Findings: 1. The collector 'road system of the Northeast Bull Mountain area is currently being evaluated by the City. A report has been prepared by City staff with several route options for the area. This site is affected by one of the routes proposed, the ext nsion of 135th Avenue to Bull Mountain Road. The tr ffic volume analysis indicates that this route will nerve as a neighborhood collector street providing access for the future residents of the immediate area to Bull Mountain Road and to Walnut Street. Through traffic from Bull Mountain Road to Walnut Street is expected to be a small percentage of the total traffic. A direct route from Walnut Street to Bull Mountain Road would encourage more through traffic than an indirect route would. The steep terrain of Bull Mountain also prevents a feasible through route without steep grades or impacts to the development of the site. Therefore an indirect connection is acceptable for this route. The proposed road incorporates system rates the indirect minor collector y � concept into its layout and is acceptable. 2. Direct vehicular access to minor collector streets is generally discouraged unless circumstances exist which prevent an alternative access. The proposed street layout proposes access to the upper half of the minor collector street by 19 lots, with additional accesses as future development to the south occurs. Traffic volumes are expected to decrease as the road approaches the mid point of the Bull Mountain /Walnut connection. Also alternative access for these lots is not available due to the restrictions of the terrain without impacts to the adjoining property and to the proposed development, therefore the direct access should be allowed. Mowe`Uer, since this route will be a minor collector street, it is rsoommended that additional measures be taken to reduce the impacts to the residences fronting this street such as additional setback requirements for the future homes. 1. Access to the site will be provided by 135th Avenue. entl.y, 135th Avenue approximately 20 foot wide paved streets hioh serves the ressidentia P r y areas of Fern Street and Walnut Street and also has some direct residential accesses. The pavement was not constructed to local street standards and is under the jurisdiction of Washington County. lt's intersection with Walnut Street dress not meet current design standards and improvements are recommended to the intersection section to improve its safety. ��cf fro analysis should provided discussing the projected traffic volumes the intersection and evaluating the necessary improvments. The improvements should provide a landing area of less than 5 percent grade and a T intersection. STAFF REPORT - i OUZAX/BURTON (S 90-01/PD 90.01/SL 90-01) PA,CaE 3 Structural improvements to the exi ►tigg 135th Avenue should be mafre since future traffic levels will increase substantially over existirg traffic levels. The pavement should receive a minimum 2 inch asphaltic concrete overlay and be widened to a minimum of 24 feet. The vertical profile should be evaluated to ensure that any improvements to 135th Avenue will match future improvements. Reconstruction, if the vertical profiles do not meet current standards, should be made by the applicant. Provisions amid be made for pedest :lan traffic along 135th Avenue, As a minimum, a gravel shoulder with a w$xith of at least 5 feet should be provided on one side of 135th. 4. Sanitary sewer service is proposed to be extended from Hart Street (Franklin Street) up 135th Avenue Into the site. Stub -outs should be provided along the route to Walnut Street and Fern Street for future extension of the public line. Serv;ca should also be extended to the south as shown'on the submitted plans. The lots which back onto the ravine on the west edge of the site may need to be served along the back side since they slope away from the street extensively. The future extension of this line should be public since it will be serving more than 16 lots. Access for maintenance vehicles and permanent easements should be provided for all lines which are outside of the public right -of- way. The construction of the sanitary sewer pipeline within the sensitive land area is necessary to provide service to the lots which border the area and are lower than the public at r e t to the east. Therefore, the engineering staff has no objection to the sensitive lands permit. 5. Storm drainage is shown to be collected on site and discharged down 135th Avenue and also into the ravine on the west edge of the cite. Since development of the site will result in an increase in the existing runoff, the drainageways should be evaluated downstream to ensure adequate facilities exist. Upgrading the drainageways to avoid impacts downstream may be necessary. The drainageway in the ravine currently passes through private property and across Fern Street. Coordination with the owners of these properties should be puroued, especially improvements are necessary to avoid impacts. The drainageway down 135th Avenue currently drains into a Swale to the east halfway isions to upgrade this drainageway orlf to direct the ,runoff down 135th Avenue should be g Y evaluated. 6. Erosion control, as outlined in the Erosion Control Plans Technical Guidance Handbook published by Portland and Washington County, will be an important as eot Of construction due to the steepness of the Oita p � g which be and the obvious amount of clearing and earthwork ich required to develop the site An erosion control plan following these guidelines is required. STAPP IMPORT - KOL' ZAX /B RTON (S 90-01 /PD 90-01/SL 90 -01) PAGE 4 Scott King, a Transportation Planner with the Washington County Land Use and Transportation Department states that the County requires a development, which generates more than 200 trips per day and accesses a County road, to submit a traffic study for County review. The trip generation for this development is 1200 ADT based upon ITE category 2-10. The applicant shall provide the County with a study prior to final approval. County review of this study may result in further requirement for public improvements. Mr. King also has the following recommendations: A. Prior to final approval and issuance of building permit: 1. Submit a traffic study pursuant to County resolution and order 83-213. CONTACT: Daryl Steffen, County Traffic Analyst at 648- 8761 for questions regarding th.la, atL y. 2. Sign a waiver not.to remonstrate against the formation of a Local Improvement District or other mechanism to improve and maintain SW 135th Avenue to County atandards between the site and SW Walnut Street. The documents required for completion of recommended condition A.2. shall be prepared by the Washington County Survey Division and recorded in the Washington County Records Department. 3. Submit plans, obtain Engineering Division approval, provide financial assurance, and obtain a facility permit for the following public improvements; a. Provide S.W. 135th Avenue between the site and S.W. Walnut Street with a minimum 22 foot width and veering surface in life expectancy of not less than five years. b. All improvements required by the County review of the required traffic Study (see recommended condition Al above). B. Prior to occupancy all road improvements required by condition a 3. a b. shall be completed and accepted to the County. Hal Bergsma, Senior Planner, also with the Washington County Land De and Transportation Department, expressed Department concerns relating to the number of trees that will need to La removed as a result of the standard subdivision and the potential impact of the proposed street loCatioe on the west side stream corridor and ravine. The Tigard Water District comments that it will require a loop System and a pressure reduction vault and valve system on 135th Avenue. The Tigard Building Division indicates that private storm drain lines must STAFF REPORT - KOUZAI/BURTON (S 90-01/PD 90-01/SL 90-01) WIGE be installed on lots 17 -27, 36 -43, 46 -55, 66 and 72 -78, 80 -89, 93 and 100 - 102, 91 and 108 -112, and 113 -119. The Tualatin Valley Fire and Rescue District indicates that hydrant placement will be coordinated through the Tigard Water ntstrict and that plans should be submitted for review and approval to the District. The Tigard School District indicates that the proposed complex is located within the Mary Woodward Elementary and Fowler Junior High School attendance boundary. This complex along with 20 others now being planned or constructed will generate 163 new students for Mary Woodward Elementary and 71 students at Fowler Junior High School, The Tigard School District may not be able to accommodate them at Mary Woodward or at Fowler. Prospective occupants should be advised that students may be bused to other schools. After the District completes its new middle school in 1992, there should room available at Mary Woodward and Fowler Junior High School for these students. Because of the time and cost constraints, it is the District policy that buses generally do not enter subdivisions. It is very important to us that your design consider space for bus pull out sufficient in size to allow traffic to pass safely without stopping. No other comments have been received, B. FINDINGS AND CONCLUSIONS The relevant approval criteria are Comprehensive Plan Policies 2.1,1, 3.1.1, 3.4.2, 3.5.1, 7.1.2, 7.3.1, 704.4, 7.6.1, 8.1.1, 8.1.2, and 8.1.3; the Bull Mountain Community Plan; and Community Development Code sections 18.54, 18.60, 18.150 and 18.160. plans acknowledged, goals longer have to these be addressed for ennon-legislative land Luse applications. lonThe Planning staff concludes that the proposal with modifications is consistent with the applicable portions of the Tigard Comprehensive Plan based upon the findings noted below. 1. Policy 2.1.1 is satisfied because the Neighborhood Planning Organization Number a, Community Planning Organization Number 4B, and the surrounding property owners ware given notice of the hearing and an opportunity to comment on the applican:°e proposal. 2. Policy 3.1.1 can be sat isfied because the Code allows development of hillsides that are steeper than 25 percent 'Alen engineering information is provided which shows that adverse environmental erosion or slope instability will not result. The applicant has submitted a general description of the site but the techniques for mitigating any potential problems related to ate k,:7 slopes have not been included, Staff does not anticipate any STAFF REPORT - I OUzAI /BURRO (S 90-01/PD 90.M1 /SL 90-01) PAGE 6 ye'st 4.11 i • V '1: • difficulties, provided that the appropriate construction and erosion control measures are employed. Since many issues regarding slopes are site specific, the staff recommends that methods for maintenance of slope stability and erosion control be submitted for the approval in conjunction with the public improvement plans and building permits with particular attention beieg paid to grades over 25 percent. 3. Policy 3.4.2 Le satisfied at the present b.cause the proposed plat does not extend into the large drainageway at the west end of the property. Eowever, the future street extension and ultimate disposition of the property has not been described by the applicant. If this portion of the peoperty is to be developed in the future, much care needs to be taken to avoid damaging the integrity of this drainageway. 4. Policy 3.5.1 indicates that the City will encourage private interests to provide open space, recreation lands, facilities, and preserve natural, scenic, and historic areas. This plat does not provide for any common open space within the development. Although the lack of common open space is not necessarily in conflict with this policy, it undoubtedly will be more difficult to preserve the the natural and scenic values of this property without it The site grading and tree removal plans required in the conditions of approval below shall be reviewed with the intention preserving the natural features of the site to the maximum extent poesible. 5. Policies 7.1.2, 7.3.1, 7.4.4, and 7.6.1 are satisfied because adequate water, sewer, and storm drainage facilities, as well as fire protection services are or will be made available to the development. The .applicant has ,indicated that these facilities will be provided within the subdivision as required by City standards. 6. Policy 8.1.1 cello for a safe and efficient street Systems that meets current and projected needs. The proposed internal street system satisfies all applicable Code and Plan street standards. 7. Policy 8.1.2 and 8.1.3 will be satisfied because the City of Tigard and Washington County have and will be working together to resolve street improvement end location issues involved in this case and the greater Bull Honntain area The proposed subdivision street improvement e will be constructed to city o County construction standards as applicable and will be installed at the developer's expense. Sufficient public right-of-way will he dedicated to the public within the subdivision for these streets. The Planning staff concludee that the proposal with mo3ification6 is consistent with the Bull Mountain Community Plan based upon the following findings 1. The density of the proposed subdivision is within the liMits contemplated by the Plan. All lots will be well above the 5,000 square foot minimum lot size of the fotmer R-6 County Plan designation, STAFF REPORT - KouzAT/EuRTON (S 00-01/PD 90-01/SL 90-01) 4 2. The ploaservation of trees is viewed as an important component of the Bull Mountain Plan's strategy for preserving wildlife habatat and related aesthetic benefits. This property is entirely within a significant natural area as identified in the Plan. These areas are considered to be important due to their natural condition as well as ecologic, scientific, and educational value. The proposed preliminary plat application does not include a plan for the preservation of trees on the property. Such a plan provided by a qualified arborist must be submitted and approved prior to removal of trees on the property or the approval of the final paat. An assesewmt of the street extension to the west and its impact upon the western ravine and stream should be accomplished prior to approval of the final plat. 3. The property is also within Area of Special Concern No. 3.. This designation has been applied because of the County's expressed desire to evaluate .significant natural areas on the north slope of Cull Mountain and to consider the possible aquisition of land as permanent open space. Thie study has not been conducted by the County or the City. The Plan text does indicate that in the interim, development may occur in a manner consistent with the Plan and applicable code provisions. 4. General design elements of the Plan include the deign of minor collector streets which will not encourage through traffic, minimize the amount of land and vegetation disturbance, limit the removal of tree e over six inches in diameter to no more than 50 percent, and the protect stream corridors. As discussed above in the Engineering Division comments, the minor collector street system is being designed primarily to serve the future development on Bull Maentain rather than through traffic. Detailed plans shall be required as a condition of approval to show that minimum of 50 percent of the trees will be preserved and that land disturbance, particularly in the ravine area, will be kept to a minimum. The Planning staff concludes that the preposal, with modifications is consistent with applicable portiens of the Tigard Community Development Code based upon the findings noted below 1. Chapter 18.52 of the Code is satisfied because the proposal does meet the density requirement of the A-7 tone. 2. Chapter 18.92 is satisfied because the proposed density is consistent with Code requirements. 3 Chapter 18.80 is satisfied because the proposal ia consistent with the purpose and requirements of this chapter pertaining to nlanned develOpmenta. Planned developments are intended to be used in STAFF REPO - KOUZAI/BURTON (S 90-01/PD 90-01/SL 90-01) PAGE 8 -01.11/1•10,12711171MIG undeveloped are such as this to better protect amenities on the site Although this section of the Code encourages the provision of common open space area through the application of flexible development standards, common areas ase not required by the Code. 4. Chapter 18.84 covers sensitive lands issues within drainageways and slopes over 25 percent. The drain=geway on the property will be avoided hOwever, as noted earlier, the future use of this section of the property must be evaluated further. Although slopes of over 25 percent will generally be avoided by this project, it is possible that some of the homesites will be located on slopes over 25 percent. Provided that grading, construction, and erosion controls are approved and monitored by the Engineering and Building Inspection Divisions for this development, the provisions of this chapter will he met. 5. Chapter 18.60 of the Code is satisfied because the proposal does meet the requirements set forth for the submission and approval of a preliminary subdivision plat. 6. Chapter 16.150 of the Code prohibits the unnecessary removal of trees over six inches in diameter.

The land is located on the Northeast side of Bull Mountain and is relatively steep with one ravine with very steep side banks. No publi tacilities currently exist La the property. The ,:pplieent has submitted a site plan showing the proposal lot layout and public road, water, sanitary sewer, and Storm drainage systems. Findings: 1. The collector road system of the Northeast Bull Mountain area is currently being evaluated by the City. A report has been prepared by City Otaff with several route options for the area This site is affected by one of the routes propped, the extension of 135th Avenue to Bell Mountain Road. The traffic volume analysis indicates that this route will serve as a neighborhood collector otreet providing access for the future residents of the immediate area to Bull Mountain Road and to Walnut Street. Through traffic from Bull Mountain Road to Walnut Street is expected to be a small percentage of the total traffic. A direct route from Walnut Street to Bull Mountain Road would encourage more through traffic than an indirect route would. The steep terrain of Bull Mountain also prevents a feaeible through route without steep grades or impacts to the development of the site. Therefore an indirect connection is acceptable for this route. The proposed road system ineorporatee the indirect minor collector concept into its layout and is aeceptable. 2. Direct vehicular access to minor cellector streets id generally discouraged e' unless circumstances exist which prelreet an alternative accese. The proposed Street layout proposes ace:zee to the upper half of the minor collector street by 19 lots, with additional accesses as future development to the south occure. Traffic volumes are expected to decrease as the road approaches the mid point of the Bull Mountain/Walnut Connection. Also alternative access for these lots is not available due to the restrictions of the terrain without impacts to the adjoining property and to the proposed development, therefore the direct acCeee should be allowed However, since this route will be a minor collector street, it is recommended that additional meaeureS be taken to reduce the impacts to die ENGINEERING COMMENTS: BURTON/KOUZAI (SUB 90-001) PAGE i , ^ g • residences fronting this street stch are additional setback requirements for the future homes. 3. Access to the gate will be provided by 135th Avenue. Currently, 135th Avenue Ls an approximately 20 foot wide paved streei which serve., the residential areas of Fern Street and Walnut Street an also has some direct residential accesses. The pavement was not constructed to local street standards and is under the jurisdiction of Washington County. It's intersection with Walnut Street does not meet current design standards and improvements are recommended to the intersection to improve the safety. A traffic analyeis should be provided discussing the projected traffic volumes at the intersection and evaluating the necessary improvments. The improvements should provide a landing area of less than 5% grade and a "T" intersection. Structural improvements to the extsting 135th Avenue snould be made since future traffic levels will increase eubstantially over existing traffic levels. The pavement should receive a minielum 2 inch asphaltic concrete overlay and be widened to a minimum of 24 feet. The vertical profile should be evaluated to ensure that any improvements to 135th Avenue will match fnture improvements. Reconstruction, if the vertical profiles does not meet current atandards, should be made by the applicant. Provisioes should be made for pedeetrian traffic along 135th Avenue. As a minimum, a iravel shoulder with a width of at least 5 feet should be provided on ene aide of 135th. 4. Sanitary sewer service Li proposed to be extended from Hart Street (Franklin Street) up 135th Avenue into the site. Stub-outs should be provided along the route to Walnut Street and Fern Street for future extension of the public line. Service should also be extended to the south as shown on the submitted plans. The lots which back onto the ravine on the west edge of the site may need to be served along the back side since they slope away from the street extensively. The future extension of this line should be a public line, since it will be serving more than 16 lots. Access for maintenance vehlclee and permenent easements Should be provided for all lines which are out of the public right of way. The construction of the sanitary sewer pipeline within the sensitive land area is necessary to provide service to the lot e which border the area and are lower than the public street they access. Therefore, the engineering staff has no objection to the sensitive lands permit. 5. Storm drainage is shown to be collected on site .:eld discharged doWn 135th Avenue and also into the ravine on the west edge of the site Since development of the site will result in an increase in the existing runoff, the drainageWaya should be evaluated downstream to ensure adequate facilitiee enist. Upgrading the drainageways to avoid impacts downstream ENGINEERING COMMENTS: BURTON/ROUZAI (SUB 90e001) PAGE 2 r • :4' y, 111. ".4 •ft • may be necessary. The drainageway of the ravine currently passes through private property and across Fern Street. Coordination with the owners of these properties ahould be Iuroued, especially if improvements are necessary to avoid impacts. The drainage-way down 135th Avenue currently' drain e into a swale to the east about halfway down the s-et. . Provisions to upgrade this drainageway or to direct the runoff down 135thVehould be se-* evaluated. Avtem.A. 6. Erosion control, as outlined in the Erosion Control Plans Technical Guidance Handbook published by Portland and Washington County, will be an important aspect of construction due to the steepness of the site and the obvious amount of clearing and earthwork which will be required to develop the site. An erosion control plan following these guidelines is required. Conditions: 1. Standard ful/ width improvements, including concrete sidewalk, driveway apron, curb, asphaltic concrete pavement, sanitary sewer, storm drainage, streetlights, and underground utilities shall be installed within the subdivision.

R MAR 2 2 1990 CITY U1- WAND PLANNING DEPT Re: Bull Mountain Summit View Estates Subdivision; Case No. S 90-01/PD 90- 01/SL 90-01 Dear Mr. Liden: I have been retained through Burton Engineering and Survey Co. as the Consulting Arborist on the Bull Mountain Summit View Estates Subdivision located off SW 135th north of the Berichview Estates Subdivision in Tigard. Due to the slopes on this site, preserving existing trees during development will be challenging. I visited the site today and I can suggest the following course of action, ffi Tree removal should take place in two steps. The first will be the removal of all the trees within the street rights of way, with the exception of the tred derF indicated to extend into the ravine and stream on the west side of the property Ai 1,00, (This street is a future addition and not part of this project). All or most of the „,,,,, tree, within the utility easement areas must also be removed. The utility 01' easements are located outside of the R.O.W. and comprise the first 15 feet inside tig* t the front property line of each lot. An additional utility easement isThM7i at the rear of thel,i,o-ts ad)acent to the northern property. line. I will observe this work to 40 determine if there are any trees which can be retained within this construclHon area Following this, I will be able to determine those areas where the trees need protection and propose methods to accomplish this Once the grades for the street improvements are established I will develop tree protection specifications. The next step in the tree removal procesg ‘,7111 be to remove trees within the future building envelope or foot print on each lot. This should include any trees which pose a hazard and any trees which will not likely survive the effects of construction. The grading on a number of lots will require significant amounts of cut or fill in order to build on them and will directly and Adversely effect some of the trees that we want to preserve. I am cautiously optimistic about the City's desire to retain at least 50% of the exieting trees, but at this point it is too early for me to determine if this is a realist :e &al. I plan to keep you apprised of the situation as construction proceeds. 1331 SW EROAOWAY surrE loo PoRTLAND, OREGON 17201 (503) 22? -4320 AELLEVOE,, WASHINO'rON1 (206) 451-0620 Mr. ',Keith .

No public facilities currently exist on the property. The applicant has submitted a site plan showing the proposal lot layout and public road, water, sanitary sewer, and storm drainage systems. Findings 1. The collector road system of the Northeast Bull Mountain area is currently being evaluated by the City. A report has been prepared by City staff with several route options for the area. This site is by proposed, volume analysis indicates that off Bull PRountai�n of Road. routes txraffiov the extension of 135th Avenat to this route will serve as a neighborhood collector street providing access for the future residents of the immediate area to Bull Mountain Road and to Walnut Street. Through traffic from Bull Mountain Road to Walnut Street is expected to be, a small percentage of the total traffic.. A direct route from Walnut Street to Bull Mountain Real would encour ge more through traffic than an indirect route would. The Steep terrain of Bull Mountain also prevent a feasible through route without steep grades or impacts to the development of the site. Therefore an indirect connection is acceptable for this route. The proposed road system incorporates the indirect minor collector concept into its layout and is acceptable. 2. Direct vehicular access to minor collector streets is generally discouraged unless circumstances exist which prevent an alternative access. The proposed street layout proposes access to the upper half of the minor collector street by 19 lots, with additional accesses as future development to the south occurs. Traffic Velumea are expected to decrease as the road approaches the mid point of the Hull . Mountain/Walnut connection. Also alternative access for these lots is not available due to the restrictions of the terrain without impacts to the adjoining property .. h proposed development, therefore the direct access should be allowed. ® However, since this route will be a minor collector street, it is recommended that additional measures be taken to reduce the impacts to the residences fronting this street such as additional setback requirements for the future homes. Acceee to the site Will be provided by 135th Avenue. Currently; 135th Avenue is an approximately 20 foot wide p aved 4treet, which serves the residential areas of Fern Street and Walnaa Street and also has some direct residential accesses. The pavement was not constructed to local street standards and is under the jurisdiction of Washington County. It's intersection with Walnut Street does not meet current .. p.. recommended to the intersection design standards and improvements are r to improve its safety. A traffic analysis should provided discussing the projected traffic volumes at the intersection and evaluating the necessary improvements. The improvements should . � provide a lauding area of less than percent "grade and a eo yH intersection. FINAL ORD � F 9dw06 P( {�UZA�/ BURTON FAGS 3 Structural improvements to the existing 135th Avenue should be made since future traffic levels will increase substantially over existing traffic levels. The pavement should receive a minimum 2 inch aephaltic concrete overlay nd be widened to a minimum of 24 feet. The vertic=• profile should be evaluated to ensure that any improvements to 135th Avenue will Match Reconstruction, if the vertical profiles do not met current standards, should be made by the applicant. Provisions should be made for pedestrian traffic along 135th Avenue. As a minimum, a gravel shoulder with a width of at least 5 feet should be provided on one aide of 135th. 4. Sanitary newer service is proposed to be extended from Hart Street (Franklin trest) up 135th Avenue into the site. Stub-outs should be provided along the route to Walnut Street and Fern Street for future extension of the public line. Service should also be extended to the south as shown on the submitted plans. The lots which back onto the ravine on the west edge of the site may need to be esrved along the back side since they slope away from the street extensisiely. The future extension of this line should be public since it will be serving more than 16 lots. Access for maintenance vehicles •and permanent easements should be provided for all lines which are outside of the public right-of-way. The construction of the sanitary sewer pipeline within the sensitive land area is necessary to provide service to the lots which border the area and are lower than the public street to the east. Therefore, the engineering staff has no objection to the sensitive lands permit. 5. Storm drainage is shown to be collected on site and discharged down 135th Avenue and also into the ravine on the west edge of the site. Since development of the site will result in an increase in the existing runoff, the drainageways should be evaluated downstream to ensure adequate facilities exist. Upgrading the drainageways to avoid impacts downstream may be necessary. The drainageway in the ravine currently passes through private property and across Fern Street. Coordination with the owners of these properties should be pursued, especially if improvement's are necessary to avoid impacts. The drainageway down 135th Avenue currently drains into a swab e to the east about halfway down the street, Provisions to upgrade this drainageway or to direct the runoff down 135th Avenue Should be future improvements. evaluated. • 6. erosion control, as outlined in the Erosion Control Plana Technical Guidance Handbook published by Portland and Waghihgtoti county, Will be an important aspect of construction due to the steepness oi the site and the obvious amount of clearing and earthwork whioh will be regnired to develop the site An erosion control plan following these guidelines is require FINAL ORDER 90-.06 PC - KoUsAI/BURTON (S 90-01/PD 90-01/St 90-01) ° g Transportation the Washington County Land Use and Scott King, a Trans nation �l+�nner with. t Transportation Department states that the County requires a development, which generates e more than 200 trips per day and accesses a County road, to submit a traffic study for County review.

Thie complex along with 20 others now being planned or constructed will generate 163 new students for Mary Woodward Elementary a School District and 71. students at Fowler Junior High Scieool The Tigard may not be able to accommodate them at Mary Woodward or at Fourier. Prospective occupants should be advised that 4 tudents may be bused to other schools. After the District completes its new middle school in 1993, there should room available at Mary Woodward and Fowler junior High School for these atudente. Because of the time and cost constraints, it is the District policy that buses generally do not enter subdivisions. It is very important to us that your design consider space for bus pull out sufficient in size to allow traffic to pass safely without stopping. No other comments have been received. B. FINDINGS AND CONCLUSIONS The relevant approval criteria are Comprehensive Plan Policies 2.1.1, The 4.4, 7.6.1, 8.1.1, 8.1„2, and 8.1.3, 3.1..1, 3.4.2, 3.5.1, 7.1.2, 7.3.1, 7. the Bull'Mountain Community Plan, and Community Development Code sections 16.54, 18.60, 18.150 and 18.160. Since these plans have been acknowledged, the stet -wide goals no longer have to be addressed for non - legislative land use applications. The Planning Commission concludes that the proposal with modifications is consistent with the applicable portions of the Tigard Comprehensive Plan based upon the findings noted below. y . Planning 1.

By creating one additional let which would include virtually all of this drainageway, the development potential for this are includ ss one single family residence. However, a future street extension and further development of the drainageway could occur.

This study has not been conducted by the County or the City. The Plan tetit does indicate that in the interim, development may occur in a manner conaietent with the Plan and applicable code provisions. 4. General design elements of the Plan include the design of minor collector streets which will not encourage through traffic, minimize the amount of land and vegetation disturbance, limit the removal of trees over sirs inches in diameter to no more than 50 percent, and the protect stream corridors.

Chapter 18.80 is satisfied because the proposal is consistent with the purpose and requirements of this chapter pertaining to planned develowiants. Planned developments are intended to be used in undeveloped 'areas such as this to better protect amenities on the site Although this section of the Code encourages the provision of common open space areas through the application of flexible development standards, common areas are not required by the Code. 4. Chapter 18.84 covers sensitive landS issues within drainageways and slopes over 25 percent. The drainageway on the property will be avoided by platting it within one lot. Although .lopes of over 25 percent will generally be avoided by this project, it is possible . that some of the homesites will be located on elopes over 25 percent. Provided that grading, construction, and erosion controls are approved and monitored by the Engineering and Building Inspection Divisions for this development, the provisions of this chapter will be met. 5. Chapter 18.60 of the Code is satisfied because the proposal does meet the requireMente set forth for the submission and approval of a preliminary subdivision plat. 6. Chapter 18.150 of the Code prohibits the unnecessary removal of trees over six inches in diameter. As noted above v a tree preservation report prepared by a qualified arborist shall be required prior to the commencement of any construction on the site 7. Chapter 18.164 of the Code will be satisfied during the approval process for the final plat. C.'

On September 11, 1989, the City Council adopted a change in zoning of the subject property from Washington County R-6 to City of Tigard R..7 PD (Residential I Units per acre, planned development). The Urban Planning Area Agreement, FINAL ORDER 9006 PC KOU2AI/BURTON (S 90-01/PD 90 =01/8L 90-01) PACE 1 "f+ ,,„ • ' between the City and Washingtc n County, require the City to adopt the zone which most closely resembles the existing Washington County zone period year. change in zoning is for a. , ,tied of the €a reem =nt one Both he Washington nCounty Bt-6 and the consistent with h g Cit y of Tigard � �� zones allow for a 5,000 s qu are foot minimum lot size for s .r gle family residences. 3 Vicinity Information S.W. 135th Avenue extends from the northeast property corner directly north to SbW. Walnut Street,. Along the property's northern border lie a number of . home sites , that generally range in size from one -half to two acres. These residences are ,located on either side of S.W. Fern Street, which runs east and west with an intereect5on with S.W. 135th Avenue at its emit end. Large undeveloped properties lie to tie east, west, and south.

S ite jnforn ati d Props sal Description The property to be developed is presently vacant and is situated on the lower portion of Bull Mountain's northern slops. The property is almost entirely. wooded. A large ravine, which runs downhill to the north, is located on the west side of the property and the remainder of the parcel slopes down to the 'northeast and east The applicant p P®s v_ ide property .. into 9 sin le family residential lots. Initially, access will only be provided by a southerly extension of 135th Avenue. This extension is intended to be a minor collector street which will continue up the hill and eventually connect with S.W. Bull Mountain Road. Other local s greets within the subdivision will, provide access to the proposed lots s well as abutting properties to the so h and west. The large westerly ravine will remain undeveloped at this point, however, the a pscant has illustrated a eonceptual street alignment which would extend across the ravine to the adjacent property to the west. A Sensitive Lands review ie also necessary because of the of the western ravine and t the possibility �bility thatiother o construction tAill occur on elopers in excess of 25 percent. The Majority of the property has sloped less than 25 percent, however it is possible that twill Occur amount c1•' . on „ peen public facility and residential construction n slo steeper: than 25 percent: 5 A en y anci Nino Comments The Engineering Division has the following comments: The applicant ro osee to d velop 39.2 acres cf vacant land _ Which ._. h has r Pp proposes y y I'ortheast recently annexed into the city. The land IS located. on the eiNee eReel en - ®6 PC - (0UZA,i/RURTOP1 (S 90- 01/Pr 90 -Q1 /SL 96 --0:1) side of Dull Mountain and is relatively sleep with one ravine with very steep side banks. No public facilities currently exist on the property. The applicant has submitted a site plan showing the proposal lot layout and public road, water, sanitary sewer, and etorm drainage systems. Findings: 1 The collector road system of " the Northeast Bull Mountain area is currently being evaluated by the City. A report has been prepared by City staff with several route options for the area. This its is affected by one of the routes proposed, the extension of 135th Avenue to Bull Mountain Road. The traffic volume analysis indicates that this route will serve as a neighborhood collector street providing access for the future residents of the immediate area to Bull Mountain Road and to Walnut Street Through traffic from Bull Mountain Road to Walnut Street is expected to be a %mall 'percentage of the total traffic. A direct route from Walnut Street to Bull Mountain Road would encourage more through traffic than an indirect route would. The steep teertain of Bull Mountain also prevents a feasible through route without *teep grades or impacts to the development of the site. Therefore an indirect connection is acceptable for this route. The ,proposed road system incorporates the indirect minor collector concept into its layout and is acceptable. 2. discouraged b streets is generally vehicular access to minor collector sty q d unless circumstances exist which prevent an alternative access. The proposed street layout proposes access to the upper half of the minor ccllector street by 19 lots with additieenal accesses as future development to the South occurs. Traffic volumes are expected to decrease as the road approaches the mid point of the Bull Mountain /Wal nut connection. Also alternative access :or these lots is not available due to the restrictions of the terrain without iMpaCts ' to the adjoining property and to the proposed development, therefore the direct access should be allowed. However, since this route will be a minor collector street, it is recommended that additional measures be taken to reduce the impacts to the residences fronting this street such as additional setback requirements for the future homes. 3. Access to the site will be provided by 135th Avenue. currently, 135th Avenue is an approximately 20 foot wide paved street, which serves the residential dential areas of Fern Street and walnut Street and also h: s some direct residential accesses. The pavement was not constructed to local street standards and is under the jurisdiction of Washineton . �� COUntyi It 'S intersection with Walnut Street does not meeet current design standards and improvements are recommended to the intersection to improve its safety . traffic traffic analysis sis should provided discussing the projected traffic volumes at the intersection and ` necessary improvements. The improvements should evaluating the '; a� prov�.c.�,,,, a landing area of less than 5 cent grade and a +,aTaa intersection. q FINAL ORDBR 90e06 PC COUZAT /BURTON (S 90- -01/PD /10 Structural improvements to the existing 135th Avenue should be ml;de since future traffic level:: will increase substantially over existing traffic levels. The pavement should receive a minimum 2 ineh, asphaltic concrete overlay and be widened to a minimum of 24 feet. The vertical profile should be evaluated to ensure that any improveMents to 135th Avenue will match future improvement6. Reconstruction, if the vertical profiles do not meet ourrent tandards, shou/d be made by the applicant. Provisions should be made for pedestrian traffic along 135th Avenue. As a minimum, a gravel shoulder with a width of at least 5 feet sould be provided on one side of 135th. 4. Sanitary sewer oervice is proposed to be extended from Hart Street, (Franklin Street) up 135th Avenue into the site. Stub-outs should be provided along the route to Walnut Street and Fern Street for future extension of the public line. Service should also be extended to the south as shown on the submitted plans. The lots which back onto the ravine on the west edge of the site may need to be served along the back side since they slope away from the street extensively. The future extension of this line should be public since it will be serving more than 16 lots. Aceess for maintenance vehicles and permanent easement should be provided for all lines which are outside of the public right-of-way. The construction of the sanitary sewer pipeline within the sensitive land area is necessary to provide service to the lots which border the area and are lower than the public street to the east. Therefore, the engineering staff has no objection to the sensitive lands permit. 5. Storm drainage is shown to bo collected on site and discharged down 135th Avenue and also into the ravine on the west edge of the site. Since development of the site will result in an increase in the existing runoff, the drainageways sisould be evaluated downstream to ensure adequate facilities exist. Upgrading the drainageways to avoid impacts downstream may be necessary. The drainageway in the ravine currently peewee through private property and across Fern street. Coordination with the owners of these properties should be pursued, especially if improvement's are necessary to avoid impacts. The drainageway down 135th Avenue currently drains into a ewale to the east about halfway down the street. Provisions to upgrade this drainageway or to direct the runoff down 135th Avenue should be evaluated. 6. Erosion control, as outlined in the EroSion Control Plans Technical Guidance Handbook published by Portland and Washington County, will be an important aspect of construction due to the steepness of the site and the obvious amount of nearing and earthwork which will be required to develop the site. An erosion control plan following these guidelinee is required. eiNen ORDER 90-06 PC KOUZAI/BURTON 0 90-01/PD 90-01/SL 90-01) PAGE 4 • Scott sting, a Transportation Planner, with the Washington County Land D = e and Transportation Department states that the County ,requires a tes more than 200 trips per day and accesses a pm which generates �' y development, County road, to submit a traffic study for County review.

FINDINGS AND CONCLUSIONS The relevant approval criteria are Comprehensive Plan Policies 2.1.1, 3.1.1, 3.4.20 3.5.1, 7.1.2, 7.3.1, 7.4.4, 7.6.10 8.11, G.1.2, and 8.1.3; the Bull Mountain Community Plan; and Community Development Liode sections 18.54, 18.60, 18.150 and 18.160. Since these plans have been acknowledged, the statewide goals no longer have to be addressed for non-legislative land use applications. The Planning Commission concludes that the proposal with modifications is consistent with the applicable portions of the Tigard Comprehensive Plan based upon the findings noted below. 1. Policy 2.1.1 is satisfied because the Neighborhood Planning Organization Number 3, Community Planning Organization Number 48, and the Surrounding property owners were given notice of the hearing and an opportunity to comment on the applicant's proposal. J.. Policy 3.1.1 can be satiafied because the Code allows development of hillsideo that are steeper than 25 percent when engineering information is provided which Ohowe that adverse environmental erosion or slope instability will not result. The applicant has submitted a general description of the site but the teChniques for mitigating any potential problems related to steep slopes have not been included. The Commission does1 not anticipate any difficultied, provided that the appropriate construction and erosion Control measures are employed and Monitored by City staff. Since many issues regarding Slopes are site specific, the staff recommesdS that methodS for Maintenance of slope stabilitY and Orosin Control be submitted for the approval in ConjUnCtibn with the public improvement FINAL ORDER 90-06 PC kODZAI/8DRTON (8 90-01/PD 90,-01/SL 90-01)i PAGt 6 - - : ; . • plans and building permits with particular attention being paid to grades over 25 percent. , Policy 3.4.2 Le satisfied at the present because the proposed p1st, as amended, does not require any extensive development in the large drainageway re the west end of the property. By creating one additional lot which would include virtually all of this drainageway, the development potential for this area includes one single family residence. However, a future c treet extension and further devalopiner ,. of the drainageway could occur. tf t',. is portion of the property iv subsequently developed, much care needs to be taken to avoid damaging the integrity of this drainag -ways Policy 3.5.1 indicates that the City will encourage private interests to provide open space, recreation lands, facilities and preserve natural, scenic, and historic areas. This plat does not provide for any colon open space within the development. Although the lack of common open space is not necessarily in conflict with this policy, it undoubtedly will be more difficult to preserve the natural and scenic values of this property without it The site grading and tree removal plans required in the conditions of approval below shall be reviewed, with the intention preserving the natural features of the site to the maximum extent possible. 5. Policies 7.1.2, 7.3.1, 7.4.4,.anad 7.6.1 are satisfied because adequate water, sewer, and storm drainage facilities, as well as fire protection services are or will be made available to the development. The applicant has indicated that these facilities will be provided within the subdivision as required by City standards. 6. Policy 8.1.1 calls for a safe and efficient street system that meets current and proj■Icteed needs. The proposed internal street system satisfies all applicable Code and Plan street standards. 7. Policy 8.1.2 and i .1. w 3 will be satisfied because the City or Tigard and Washington County have and will, be working together to resolve P street improvement and location issues involved in this case and the greater Bull Mountain area The proposed subdivision street improvements will be constructed to City er County standards as applicable and will be installed at the developer's expense. Sufficient public right - of-way w...11 be dedicated to the public within the :subdivision for these streets. g proposal The Planning Commission concludes that the r© call with modifications as consistent with the Bull Mountain Conmuni.te Plan based upon the following findings: 1. The density of the ro posed saubdivisioe is within y e= the ,� A the limits contemplated by the Plan. All lots will be well above the 50000 Square foot minimum lot size of the former R -6 County Plan designation. The preservation of trees is viewed as n important component of the Bull Mountain Plan's strategy for preserving Wildlife habitat And P /twit; ORDER 90 -b6 PC XO Z I %BURT M related aesthetic benefits. Thi. property is entirely within a significant natural area as identified in the Plan. These area are considered to be important due to their natural condition ae well as ecologic, scientific, and educational value. The proposed preliminary plat application does not include a plan or the preservation of trees on the property. Such a plan provided by a qualified arboriut must be submitted and approved prior to removal of trees on the property or the approval of the final plat. An assessment of the impact of developMent upon the western ravine and stream should be accomplished prior to approval of the final plate The amendment of the plat suggested by the applicant at the hearing to include the ravine in the plat ae one additional.lot will assist in meeting the standard for tree preservation.

The property is also within Area of Special Concern No. 3.. This designation ha o been applied bebadse of the County's ekpressed desire to evaluate significant natural areas on the north slope of Bull Mountain and to consider the possible acquisition of land as permanent open space. This study has not been conducted by the County or the City. The Plan text does indicate that in the interim, development may occur in a manner consistent with the Plan and applicable code provisions. 4 General design elements of the Plan include the design of minor collector streets which will not encourage through traffic, minimize the amount of land and vegetation disturbance, limit the removal of trees over six inches in diameter to no more than 50 percent, and the protect stream corridors. As discussed above in the Mngineering Division comments, the minor collector street system JO being designed primarily to serve the future development on Bull Mountain rather than through traffic. Detailed plans shall be required as a condition of approval to show that minimum of 50 percent of the trees will be preserved and that land disturbance, particularly in the ravine area, well be kept to a minimum. The Planning Commission concludes that the propodal, with Modifications is consistent with applicable portions of the Tigard CoMmunity Development Code based upon the findings noted below: 1. Chapter 18.52 of the Cod' satisfied because the proposal does Meet the density requirement of the R.-7 zone. , 2. Chapter 18.92 ie satisfied because the proposed density is consistent with Code requirements. • FINAL OLDER 90-06 Pd X00ZAI/BURTON (.9 90-01/Pb 90-01/SL 90-01) 3. Chapter 18.80 is satisfied because the proposal is consistent with the purpos and requirements of this chapter pertaining to planno6 development0. Planned developments are intended to be used in undeveloped or.vas such as this to better protect amenities on the site. AithOugll seCtion of the Code encourages the provision of common open space, areas through the application of flexible development st,..ndards, common areas are not required by the Code. 4. Chapter 18.64 covers sensitive lands issues within drainageways and slopes over 25 percent. The drainageway on the property Will be avoided by platting it within one lot. "Although slopes of over 25 percent will generally be avoided by this project, it is possible that some of the homesites will be located on slopes over 25 percent. Provided that grading, construction, and erosion controls are approved and monitored by the Engineering and Building Inspection Divisions for this development; the provisions of this chapter will be met. 5. Chapter 18.60 of the Code is satisfied because '0,13 proposal does meet th* requirements set forth for the submission an approval of a preliminary subdivision plat. 6. Chapter 18.150 of the Code prohibits the unnecessary removal of trees over six inches in diameter. As noted above, a tree preservation report prepared by a qualified arborist shall be required prior to the commencement of any construction on the site. 7. Chlipter 18.164 of the' Code will be satisfied during the approval process for the final plat, C.

The Flanning Commission and City Council have reviewed various aspects of this proposed dvelopment at several different times resulting in a number of different deadlines. 1 agree with you that it is very important that we straighten out the timeframes applicable to this development in order to avoid future confusion. Phase I, the Bull Mountain Summit View Estates subdivision., was approved by the Planning Commission on arch 7, /990 with an eighteen month approval period for submittal of a final subdivision plat. The final plat for Phase I was submitted in November, 1990, within the eighteen month approval period As you know, signing of the final plat by the City has been delayed by the d'eveloper's inability to construct improvements to SW 135th Avenue and to post a maintenance bond for the public improvements. Since the majority of the work is complete and the final plat was submitted in a timely manner, there is no pending approval expiration for Phase I. Phase IIA, which was referred to as the suit at Bull Mountain subdivision, was approved by .the Planning Commission on, May 0, 1990. The Commission's decision was upheld by the City Council on appeal on June 19th, 19900 An eighteen month approval period for submittal of a final subdivision plat began with the Council's decision on the appeal. That approval period was to run until December 18, 1992. On September 25 1991 , the Planning Commission approved a , preliminary plat far Phase II8 of the Summit at Bull Mountain re date, Commission also approved a rephasingaschedule for all of II and IIB. The Com ssi,on's p g reset the clock for al . of p � thl of •Phase IT effectively , _ approval of the re h all oi Phase Zori an eighteen month approval g p period expiring on March 25, 1993. Therefore, the final plat for at least one phase of Phase 11 must be 'submitted for final approval 97.22a and the necessary City signatures by that date. One one -year extension of that approval period may be requested. The Commission's September 25# 19 91 final order repeated the Community Development Code's directive that "the maximum time for completion on of all phases of the roved planned development is seven years."' Since the Since portions of the proposed development that were reviewed by the Con fission as a single package or planned development were Phases ITA and /XS /i.e., Summit at Bull Mountain): , we interpret this condition to only apply to those phases and not Phase 1. The City of Tigard Engineering Department construction .. on A on February 21, 1991. Some construction has alread ® begun se 'IA IIA although this activity has now ceased due to the difficulties that the developer has run into Because construction activity for Phase XI is deemed to have begun With approval of those construction plans, construction plans must be approved and all fees must be paid for the reainder of Phase XI no later than February 28# 19 9 d confusion that may exist regarding ... p� th�,�� clarifies any �: �' - � hope that this development.

Box 23397 Tigard, Oregon Ref: Summit at Mall Mountain Dear Jerry: This is in follow -up to the meeting I had with you and Dick Bewersdorff at your office to discuss Benchmark Land Company's interest in the Summit at Bull Mountain. At that time, we discussed the duration of the existing approvals and when they would expire, and/or need to be extended. As an example, one of the summary paragraphs on page 13 of the September 25, 1991 report states, ° The maximum time for completion of all phases of the approved planned development is seven years." Question. From what date did the "seven ear ti span ®d begin? The September 25, 1991 date? Question. What does " completion of all phases" mean? Perhaps the plans for the fine phase have to be submitted and approved within seven years? We really need specific guidance regarding the existing approval.; for the Summit at Bull Mountain It would be very helpful, if the City Attorney would review these approvals and e stallisti specific dates when extensions are required, and/or approval expire, This will avoid future confusion, and possibly our interpreting the tircframes in a manner that could eventually put the balance of the project in jeopardy.

Findings: ,. The collector road system of the Northeast Bull Mountain area is currently being evaluated by the City. A report has been prepared by City staff with several route options for the area. This site is affected by one of the routes proposed, the extension of 135th Avenue to Bul]. Mountain Road. The traffic volume analysis indicates that this route will serve as a neighborhood collector street providing access for the future residents of the immediate area to Bull Mountain Road and to Walnut Street. Through traffic from Bull. Mountain Road to Walnut Street is expected to be a smell percentage of the total traffic. A direct route from Walnut Street to Bu.]. Mountain Road would encourage more through traffic than an i direct route would. The steep terrain of Bull , Z2ountait aso prevents a feasible through route withoet steep grades or impacts to the development of the site. Therefore an indirect connection is acceptable for this route. The proposed road .system incorporates the indirect miner collector concept into its layout and is acceptable. 2. Direct vehicular access to minor collector streets is generally discouraged unless circumstances exist which prevent an alternative access. The proposed street layout proposes access to the upper half of the minor collector street by 19 lots, with additional accesses as future'development to the south occurs. Traffic volumes are expected to decrease as the road approaches the mid point of the Bull Mountain /Walnut connection. Also alternative access for these lots is not available due to the restrictions of the terrain without impacts to the adjoining property and to the proposed development, therefore the direct access Elhould be allowed, However, since this route will be a minor collector street, it- is recommended that additional measures be taken to reduce the impacts to the residences fronting this street such as additional setback requirements for the future homes. 3. Access to the site will be provided by 135th Avenue. Currently, 135th Avenue is an approximately 20 foot wide paved street, which serves the residential areas of Fern Street and Walnut Street and also has some direct residential accesses. The pavement was not constructed to local street standards and is under the jurisdiction of Washington county. It's intersection with Walnut Street does not meet current deli. n standards and :gym rcvements are recommended to the intersection 9 p to improve its safety. A traffic analysis should be provided discussing the projected traffic' volumes at the intersection and evaluating the necessary improvements. The improvements should provide a landing area of less than 5 percent grade and a `t° intersection. FINAL ORDER 90-06 PC - KOUZAI /i URTOt1 (S 90- -01 /PD 90 -01 /SL 90.01 Structural improvements to the existing 135th Avenue should be made since future traffic levels will increase substantially over existing traffic levels. Tine pavement should s. °:ceve a minimum 2 inch asphaltic concrete overlay and be widened to a minimum of 24 feet. The vertical profile should be evaluated to ensure that any improvemnents to 135th Avenue will match future improvements. Reconet:uotion,, if the vertical profiles do not meet current standards, should be made by the applicant. Provisions should be made for pedestrian traffic along 135th Avenue. As a minimum, a gravel shoulder with a width of at least 5 feet should be provided on one side of 135th. 4. Sanitary sewer service is proposed to be extended from liart'Street (Franklin Street) up 135th Avenue into the site. Stub -outs should be provided along the route to Walnut Street and Fern Street for future extension of the public line. Service should also be extended to the south as shown on the submitted plans. The lots which back onto the rwv ine on the west edge e.ei the site may need to be served along the back side; since they slope away from the street extensively. The future extension of this line should be public since it wa.].l be serving more than 16 lots. Acpeas for maintenance vehicles and permanent easements should be provided for all lines which are outside of the public' right -of -way. The construction of the sanitary Oewer T4.peline within the sensitive land area is necessary to provide service to the lots which border the area and are lower than the public street to the east. Therefore, the engineering staff has no objection to the sensitive ianda permit. Storm drainage is shown to be collected on site and discharged down 135th Avenue and also into the ravine on the west edge of the site. Since development of the site will result in an increase in ` e existing runoff, the drainageways should be evaluated downstream to ensure adequate facilities exist. Upgrading the drainageways to avoid impacts downstream may be necessary. The dral.nageway in the ravine currently passes through private property and across Fern Street Coordination with the owners of these properties should be pursued, especially if improvements are necessary to avoid impacts. The drains g g ewa Y down 135th Avenue currently drains into a stale to the . east about halfway down the street. Provisions to upgrade this g y the .

FINDINGS AND CONCLUSIONS The relevant approval criteria are Comprehensive Plan Policies 2.1.1, 3.1.1, 3.4.2, 3.5.1, 7.1.2, 7.3.1, 7.4.4, 7.6.1, 8.1.1, 8.1.2, and 8.1.3; the Bull Mountain Community Plan; and Community Development Code sections 18.54, 18.60, 18.150 and 18.160. Since these plans have been acknowledged, the statewide goals no longer have to be addressed for non-legislative land use applications, The Planning Commission concludes that the proposal with modifications is consistent with the applicable portions of the Tigard Comprehensive Plan based upon the findings noted below. 1. Policy 2.1.1 is satisfied because the Neighborhood Planning Organization Number 3, Community Planning Organization Number 4B, and the surrounding property owners were given notice of the hearing and an opportunity to comment on the applicant's proposal. 2d Policy 3.1.1 can be satisfid because the Code allows development of hillsided that are steeper than 25 percent when engineering informaflion is provided which shoWs that adverse orwironmentP1 erosion or slope instability will not result. The applicant 111.1s submitted a general description of the site but the Lechnigues for mitigating any potential problems related to step slopes have not been included. The Commisdion doeS not anticipate any difficulties, provided that the appropriate construdtion and erosion control mestires are employed and monitored by City staff, Side many issues r°141trding slopes are site spedific, the staff r(..:ommends that Methods for maintenance of slope stability and erosion control be submitted for the approval in conjunclilion With the pubic improvement FINAL ORDER 90,-06 PC - KOU2AI/BURTON (S 50-01/PD 90-�l/SL 90-01) PAGE 6 plans and building permits with particular attention being paid to grades over 25 percent. 3 Policy 3.4.2 is satisfied at the present because the proposed plat, ao amended, does not require any extensive development in the large drainageway at the west end of the property. By creating one additional lot which would include virtually all of this drainageway, the development potential for this area includes one single family residence. However, a future street extension and further development o$' the drainageway could occur. If this portion of the property as subsequently developed, wurh care needs to be taken to avoid damaging the integrity of this drainageway. 4. Policy 3.5.1 indicates; that the City will encourage private interests to ...,covide open space, recreation lands, facilities, and preserve natural, scenic, and historic .areas. This ' plat does not provide for common open any c • o space within the development. Although the lack of P common open space is not necessarily in conflict with this policy, it undoubtedly will be more difficult to preserve the natural and scenic values of this proferty without, it. The site grading and tree �" removal plans required in the candittons of approval below shal l be reviewed. with the intention preserving the natural features of the site to the maximum extent possible. 5. Policies 7.1.2, 7.3.1, 7 .4.8„ . and 7.6.1 are s atisfied because adequate drainage facilities, as well as fire water, sewer, . and storm drai b e to the development. p are or will be made available refection services indicated that these facilities will be provided The applicant has a. within the subdivision as required by City standards. 6. Policy X .1.1 calls for a safe and efficient street system that meets current and projected needs.

This property is entirely within a significant natural area as identified in the Plan. These areas are considered to be important due to their natural condition as well as ecologic, scientific, and educational value. The proposed preliminary plat application does not include a pan for the preservation of trees on the property. Such a plan provided by a qualified arborist must be submitted and approved prior to removal of trees on the property or the apptoval of the final plat. An aaaessment of the impact of deVelopMent upon the western ravine and stream should be accomplished prior to approval of the final plata The amendment of the plat suggested by the applicant at the hearing to include the ravine in the plat as one additional lot 'oil' assist in meeting the standard for tree preservation. Having one large lot with an allowance for one residence will make it possible to leave the majority of the parcel in its natural state, If this lot is developed in the future, the Citztmine ' complianne with the 50 ercent tree reservation standard baIeLITSIALAILMSTAIIIL..:0112MSIY which is subjet of this applica 3. The property is also within Area of Special Concern No 3.. This designation has been applied beeause of the County's expressed desire to evaluate significant natural areas on the north slope of Bull Moantain and to consider the possible acquisition of land as permanent open space. This study has not been conducted by the County or the city. The Plan text does indicate that in the interim, development may occur in a Manner consistent with the Plan and applicable code provisions. 4. General design elements of the Plan include the design of minor collector streets which will not encourage through traffic, mlnimize the amount of land and vegetacion disturbance, limit the removal of trees over six inches in diameter to no more than 50 percent, and the protect stream corridors. As discussed above in the Engineering Diviaion comments, the minor collector street system is being designed primarily to serve the future development on Bull Mountain rather.' than through traffic, Detailed plans shall be required as a condition of approval to show that minimum of 50 percent of the trees will be preserved and that land disturbance, particularly in the ravine area, will be kept to a minimum. The Planning Commission concludes that the proposal, with modifications is consistent with applicable portions of the Tigard Community bevelopMent Code bad upon the findings noted below: 1. Chapter 18.52 of the code it satisfied because the proposal does meet the density requirement of the R-7 zone. 2 Chapter 18,92 is satisfied because the proposed denaity is consistent with Code requireMents. FINAL ORDER 90-06 Pd KOUZAI/BURTOM ( 90-01/P0 90-01/St 90-01) 3. Chapter 18.80 is satisfied because the proposal is consistent with the purpose and requirements of this chapter pertaining to planned developments. Planned developments are intended to be uAed in undeveloped areas such as this to better protect amenities on the site Although this section of the Code encourages the provision of common open space areas through the application of fleOtible development standards, common areas are not required by the Code. 4. Chapter 18.84 coveses sensitive lands issues within drainageways and slopes over '25 percent. The drainageway on the property will be avoided by platting it within one lot Although elopes of over 25 'percent will generally be avoided by this project, it is possible that some of the homesites will be located on slopes over 25 percent. Provided that grading, construction, and erosion controls are approved ' and monitored by the Engineexing and Building Inspection Divisions for this developMent;' the provisions of this chapter will be met. 5. Chapter 18.63 of the Code is satisfied because the proposal does meet the requirements set forth for the submission and approval of a preliminary subdivision plat. 6. Chapter 18.150 of the Code prohibits the unnecessary remova/ of trees over six inches in diameter. As noted above, a tree preservation report prepared by a qualified arborist shall be required prior to the commencement of any construction on the site. 7. Chapter 18.164 of the' Code will be satisfied during the approval process for the final plat. C.'

Your 62.89 acre parcel is divided by two separate zoning districts. The southwesterly parcel is 15.08 acres with an existing zoning of R-7, which allows for 105 units. This 15.08 acre parcel is proposed to have 45 single family lots, of which 33 SP lots have received preliminary plat approval from the City of Tigard" The balance of the property (47.81 acres) has an existing City of Tigard R4.5 PD (Planned, Development) zoning There i5 a 3.0 acre proposed church site located at the southeasterly corner of the site. To determine the allowable density in the PD portion of this property we subtracted out the 3.0 acre church site, which leaves this site With 44.81 acres X 4.5 units �. this acre equals 202 allowable units. Under the PD zoning dis- trict, y r of units is allowable, wherein t development proposes 80 single family lots taking 'gip .approxi- mately 24 acres, open space or parks taking up approximately 10 acres, and 126 townhouse units within 10.81 ` acres. • A�z application for outline master plan approval of a planned development has been submitted to the City of Tigard for their reveiw.

INTRODUCTION' Residential development is pxoposed for a 60-acre parcel (Bull Mountain Project of Oregon), located north of SW Bull Mountain road, west oi Gaarde 8treet, and south of Walnut Street in Tigard, Oregon. This site lies on the northeast-facing slope of Bull Mountain. The vegetation consists of grasslands which were probably formerly filbert orchards or grazed until recently, filbert orchards which are no longer maintained, and second-growth mixed forest. Small, intermittent tributaries of Fanno Creek drain this parcel. The southernmost portion of the property is within unincorporated Washington County; the remainder is within the City of Tigard. The City of Tigatd's policy regarding natural areas (Policies 3.4,1 and 3.4.2) mandates protection of fish and wildlife habitat along stream corridors. The protection mentioned inclUdes erosion controlling measures, maintenance of existing tree corer to the maximum extent possible, and review of development proposals in forested areas. The Bull Mountain Community Plan (1983), which applies to the part of the site Outside of the City Of Tigard, identifies the forested pa,7t of the property as a signiiicant natural area Significant natural areas are definel as 'Site S of special importance, in their natural condition, for their ecologic, scientific, and educational value." The plan further states that there are large areas of contiguous forest, with some old growth trees, on the north slope of Bull Mountain, and that wooded areas in riparian zones along waterways comprise significant wildlife habitat. The site is within and adlacent to Area of Special Concern 3 on the Bull Mountain community Plan. The area of special BUD. Mountain ProJect Report Page 2 concern designation calls for examination of the Significance of the area, ,giving special attention to wildlife and old growth elements, and including representatives of ODFW, MPRD, citizens and groups, during development of the County-Wide Park and Recreation Master Plan. The Park and Recrea iln Plan could eventually include provisions for acquisition of lands through either purchase or dedication. This Flan has not been completed and development consistent with other provisions of the Comprenhensive Plan will be permitted in the ante, irn. This report provides an overview of the soils, vegetation and ecological characteristics of the 3ul`l Mountain site The upland and riparian habitats are described and mapped. Recommendations are made as to hoer riparian wetland areas and other significant wildlife and natural features can be protected during and after development. A plant and animal species list is also provided in this report. A general assessment is made 6f probable env '€onmental impacts of residential development on the site, and recommendations to avoid or minimize adverse impacts are given. 2. METHODS During November 1988, the vegetation and wildlife of the Bull Mountain site were inventoried. All plant and animal species (or recognizable signs) were recorded. Dominant species in each vegetation type were noted and the field notes were co spared to the published literature and agency file information including the U.S. Fish and Wildlife service's National Wetlands Inventor' maps.' The boundaries of riparian wetland vegetation along the creek and tributary drattages were mapped in the field on an aerial' photograph. Bull Fountain Project Report 1 3. EXISTING CONDITIONS All plant and animal species observed are listed in Table 1, included at the end of this report. No rarer threatened: endangered, or special-status plants or animals are known to occur on this site, based on field observations, existing habitat conditions, and consultation with the Oregon Natural Heritage Data Base. The vegetation of the site is mapped in Figure 1. Overall, considering its use history, the vegetation and wildlife habitat at this site are in good condition. 3.1 Soils Soils of the site consist of lornelius and Kenton silt loams varying from 2 to 30 percent slopes (Green 1982). These soils are not classified as hydric„ indicating that wetland conditions do not exist outside of a narrow strip along the streams draining the site. 3.2 Forested ..1 lands The wooded part of this site is fairly typical of forest in the foothill regions of the Willamette Valley (Franklif), and Dyrnes0 1973). This second-growth forest appears to have ben logged about 50 years ago. The canopy is dominated by DoUglas fir and red alder. The largest trees (Douglas fir and bigleaf maples) range up to approximately 80 feet in height and 14 inChes dbh, althOUgh a few larger Douglas fir are present. No old-growth size trees were observed, Alders range up to about 60 feet in height. Canopy cover exceeds 80 percent. One 20-foot western red cedar was observed, otherwise, there is no conifer reproduction. Dominant shrub8 in the understory include salal* trailihg blackberry* thimbleberry„ atld Cascade oreqengrape. Other Common shrubs include vine maple, red huckleberry, elderberry* hazel, rose, cascara, Bill MoOntain Project Report Page • oceanspray„ pacific ninebark„ and scouter s willow. At this time of year (November) the herbaceous understory is comprised primarily of swordfern. Other common herbs identified include vetch, pig-a- back plant, bracken fern, vanilla leaf, duckfoot, twisted stalk, and geranium. These upland forests intergrade into the riparian forest along the streams draining the site. This forest contains only a small number of dead trees (snags). All of these snags show evidence of frequent use by woodpeckers, especially the pileated woodpecker. An adult male pileated woodpecker was observed excavating holes in a Douglas fir in the northeast corner of the site Recent pileeited workings were observed elsewhere throughout the forested a7ea. These forested area provide habitat for a eiversity of other wildlife species: including the varied thrush, American robin, chickadee- golden- crowned kinglet, raccoon, black-tailed deer, and small mammals such as Townsends chipmunk and Douglas squirrel. Decomposing logs on the ground provide regeneration sites for some tree species, cool moist microhabitat for some reptiles and amphibians: and cover for mice and shrews. The avian and small mammal prey base probably helps support predators like the great horned owl. 3.3 Wetlands andllEaLian Vegetation The U.S. Fish and Wildlife Service's National Wetlands Inventory (1981) identifies palustrine (meaning within a Channel), forested, deciduous wetlands along the lower part of the main stream at the Bull Mountain site Topography influences the extent of wetland atea along the.stream. At the upper tributaries, the channels are generally deeply incised and the width of the wetland probably does not exceed a few feet. Deeply incised sections lack vegetation, while other sections have woody debris to dissipate the flow and provide substrate for invertebrates, In souse Pladasi fallen trees ha .e created small debris and logjams along the Bull Mountain Proiect Report Page 5 streams. No submerged or emergent wetland vegetation was observed, nor were any fish observed. At the lower end of the main stream, a flat floodplain 'about 20 feet wide (probably occupied by wetland vecietation) exists. A distinct boundary between the wetland and riparian transition zone vegetation is not evident as very little vegetation was identifiable in this floodplain area at this time of year. The riparian zone along the entire length of the streams tends to be dominated by deciduous rather than coniferous trees (Oakley et al. 1905). The deciduous trees and shrubs along the stream are evident in Figure 1 as the lighter-eolored trees. The riparian area along the creek is very go,A condition. Vegetative diversity is moderately high, and the riparian vegetation is representative of that expected in the Willamette Valley (Franklin and Dyrness 1973), considering the limitations of the time of year In addition to bigleaf maple and red alder, a few scattered cottonwoods occur along the creek. There is also an increase in the density of vine maples along the itream. There is a small pool above a crossing of the tributary coming in from the northwest corner of the site. It was created by the crossing fill and the fact that the intake of the CUlvert is about a foot above the current level of this pond. This pond ay be dry during the drier part of the summe , but probably provides breeding habitat for a variety of amphibians, including species such as the pacific treefrog and rough-skinned newt. 3 , 4 Meadow The open meadoW areas were dominated by tail (waist-high) fescue and orchardgrass. Other grasses were not identifiable. Some of the common, identifiable forbs observed include red clover, tansy ragwort, St. John's wort, dandelion, willow-herb, cinquefoil, aster, Queen Anne's lace, plantain, and dock. TheSe meadow areas were actively hunted by a red-tailed hawk and are prehably used by Bull mountain Project Report page 6 • American kestrels during the summer. An accipiter (either a female sharp-shinned hawk or a male Cooper's hawk) was observed harassing the red-tailed hawk during the site visit. 3.5 Old Filbert Orchards Filbert orchards which are no longer maintained,also exist on the property. These areas have been invaded by himalayan blackberry and support a variety of other species, including holly alder and filbert saplings, one-seeried hawthorn, swordfern grasses, vetch, bedstraw, thistle, hawkweed, and trailing blackberry. Freh black-tailed deer sign, scrub and Steller's Jays/ chickadees, northern flickers, and Douglas squirrels were observed. Other woodpeckers and a diversity of small mammals undoubtedly utilize the site In combination with the adJacent forest and fields, this old orchard probably supports raptors such as the screech owl and red-tailed hawk. 4. IMPACTS Potential short-term (temporary) impacts of construction include increased turbidity and potential Siltation and sedimentation of the stream from erosion of exposed soils; and increased noise and dust. Long-term impacts include surface water quality declines from runoff of herbicides and fertilizers/ inereased zunoff rates and decreased groundwater infiltration from an increase in impervious surfaces, and loss of upland wildlife habitat. This development will cause a loss of plleated woodpecker habitat that can be at least partially mitigated. As residential development of this forested area on Bull Mountain proceeds, the cumulative effect may be the eventual loss of pileated woodpeckers and other species such as the red-tailed hawk from the area if the habitat area and quality declines to a level that no lunger Meets the requirements the now-resident birds. Some of these imPactS can • :•13ui1 i400411ti Pale 7 • be avoided or mitigated; ethers are unavoidable (see Section 5). 5. MITIGATION ' Turbidity and siltation increases can be avoided by proteCting the natural resource zone along the streams, as is proposed. The dedicated stream corridor adjacent to lots 62-64 and 94-9S is very narrow. Giving consideration to redesigning this stream buffer is recommended, as the width of the dedicated corridor here is far narrower than anywhere else in the plan and may not be adequate to protect the stream. Establishing an additional buffer zone protected by covenants to individual lots bordering the dedicated natural resource area would also be desirable. Maintaining a zone of 10 feet or so adjacent to the dedicated natural resource area in native, unmowed vegetation to intercept fertilizers and herbicides used in yard maintenance would further protect the quality of the stream and protect slope stability. Encouraging landowners to landscape with native species of value to wildlife will partly offset wildlife habitat losses. A list of recommended plant species is given in Table 2. Other mitigation activities relate primarily to preserving as much additional native tree, shrub, and ground cover as possible. These activities include designing street, utility, and house placement to preserve as many trees as possible and preserving corners or strips of native shub and ground cover ih yards during construction. It may also be possible to protect some of these upland area by covenant. Preservation of the dedicated area alOng the stream will serve to maintain a corridor of natural vegetation along the stream. This corridor will serve as a refuge and avenue of dispersal and movement frn: local vegetation and wildlife within the much larger system of contiguous filroodiands along the north Bull Mountain Project Report Page 8 • , • '1.}. P484. slope of Bull Mountain which are in turn connected to the Fanno creek 3yster (and Tualatin River) by this and the other small stream corridors draining Bull Mountain. Leaving snags in the dedicated area, and prohibiting rf!Emoval of trees that in the future, will enhance cavity-using wildlife habitat. Creating a dozen or so new snags within the dedicated area by killing live trees would partially offset the inevitabl= loss of pileated woodpecker habitat that will result from this development. Herbicide injection is the recommended method to create snags in this situation. Dust car; be controlled by periodic application of water to exposed soils during dry weather. Increased noise, decreased groundwater infiltration, and upland wildlife habitat 1osr are unavoidable adverse impacts Overall, implementation of the mitigative, measires described above will preserve important riparian and wetland values at the site, while minimizing adverse impacts bn upland natural resources and permitting development to occur on this site. 6 .

Friday afternoon Ken Bower from the county called about the street games in the plat All of the current street names in Summit ( Bull tn.

However, when we were looking at the street grid and possible alignments in Phase 11 we hesitated to ass441 the numbered avenues because of their looping and tennmating characteristics. From what Ken says, Burton has the mylars in hand and is currently making corrections. The street names assigned must make sense to the whole development or addressing becomes a nightmare. Until we have an everall development plan for all phases that is approved by the Planning Commission showing h ow and where the subdivision streets connect to Bun Mountain Road and other surrounding subdivisions, we have little hope of assigning final street names to the first phase subdivision plat Ken will call Burton Engineering and have them get in touch with us Planning File Randy wooley June 24, 1992 Mr. Mark Rockwell Benchmark Land Company CF IF TIG OREGON RE: Director's Interpretation of Timelines for Summit at Bull Mountain Subdivision/Planned Development Dear Mark: • Yot have asked for * an interpretation of the City of Tigard's imposed deadlines xelated to development of the various phases of the Summit at Bull Mountain subd'ivision.

Mountain :Sumutit.:View. Estates subdivision, was pproved by the Planning Commission on March 7, 1990 with an eighteen month approval. period for submittal of a final subdivision plat. The final plat for Phase I was submitted in November, 19901 within the eighteen month approval period.,.„As.you know, signing of the final plat by the City has been delayed . by the developer's inability to construct improvements to SW 135th Avenue and to post a maintenance bond for the public improvements. Since the majority of the work is complete and the final plat was submitted in a timely manner, there is no pending approval expiration for Phase I. Phase IIA, which was referred to as the Summit at Bull Mountain subdiviion, was approved by the Planning Commission on May 8, 1990. The Commission's decision was upheld by the City Council on appeal on June 18th, 1990. An eighteen month approval period for submittal of a final subdivision plat began with the Council's decision on the appeal. That approval period was to run until December 18, 1992. On September 25 1991, the Pi ,Inning COMO, S sion approved a preliminary plat for Phase IIB o. the Summit at Bull Mountain subdivision. On that date, the,. Commission also approved a rephasing schedule for all of Phases IIA and IIB. The Commission's approval of the rephasing plan for all of Phase II effectively reset the clock for all of Phase 11 wth an eighteen month approval period expiring on March 25# 1993.

At that time, we discussed the duration of the existing approvals and when they would expire, and/or need to be extended. As an example, one of the summary paragraphs on page 13 of the September 25, 1991 report states, "The maximum time for completion of all phases of the approved planned development is seven years." Question. From what date did the "seven year" timeperiod begin? The September 25, 1991 date? Question. What does "completion of all phases" mean? Perhaps the plans for the final phase have to be submitted and approved within seven years? We really need specific puidance regarding the existing approvals for the Summit at Bull Mountain. It would be very helpful, if the City Attorney would review these approvals and establish specific dates when extensions are required, and/or approvals expire, This wi/1 ivoid future confusion, and possibly our interpreting the tirneframes in a manner that could eventually put the balance of the project in jeopardy, Sincerely, Mark Rockwell Partner TO s Tone Burton, Barton Engineering a Survey Larry Smith, Malrr Coast.

This subdivision is somewhat unique in that it is located away from a major collector street and it abuts the boundary between the Tigard and Beaverton School Districts After some discussion with Bud, it appears that school buses will likely approaCh this subdivision from the south (along the proposed new road connection from Bull Mountain Road) rather than from Walnut Street. As this area develops, it is expected that school buses will actually circulate on local street 1 through the Three Mountains Subdivision, the proposed new subdivision on the former Zednick property, and the Burton /Kouzai development. The bus routes will be on local streets rather than major collector streets.

So, 1 will attempt to clarify that procedure in writing. Perhaps you can share .thie letter with any of the CPO members who are concerned. The approval of a new subdivision is a three-step process. The first step is the preliminary plat approval. This approval is granted by the Planning Commission (or, for some subdivisions, the Beatings Officer) after conducting a public hearing on the proposal. At the hearing, the Commission typically receives recommendations from neighborhood groupd, from other agencies, and from the City staff. In approving the preliminary plat, the Planning Commission can attach conditions. The conditions can require improvements outside the subdivision, such as improvement of access roads. The Planning Commission conditions can be quite detailed. However, more commonly, the Oommispion describes in general terms the type of improvements to be required or the areas of concern which they want the developer to address. The decision of the Commiseion is final unless it is appealed within 10 daya following approval of a final order. The second step Jo the approval of the detailed construction drawings and the final plat map. This approval is granted by City staff. Before staff can approve the drawings, they must determine that the plans satisfy all of the conditions of the Planning Commission approval and all of the requirements of the City's ComMunity Development Code (CDC). The CDC establiehee design standards for sUbdivisions and associated public improvemente. In addition, staff will require the posting of bonds to assure that the improvements will be made in accordance with the approved plane. The third step is City acceptance of the improvemente. Before the City accepts the improvements and releases the bonds, the developer must Satisfy the City inspection staff that all of the required improvements haVe been completed in accordance with the approved construction drawings. After the City hae determined that all of the required construction has been Satisfactorily completed, the developer id required to guarantee the construction for a period of one year and to post a bond to assure the guarantee. If problems Should be found in the construction during the guarantee period, the developer in required to repair or rebuild the improvement as necessary to resolve the problem. 13125 SW Hall Blvd., O.

The neighbors have asked me to speak on their behalf regarding this development. We would like to express our gratitude and appreciation to the developers and their representatives, for their openness and cooperation with our neighborhood during this planning process. We recognize that the developer has taken our comments seriously, and has made substantial changes in his design plans to accommodate our concerns. We are grateful for this effort. We believe that the planned development is well designed, and ask the Planning Commission to approve the site plans in their current form. During the planning process, the developers have been solicitous of people's concerns about improvements on SW 135th Street where it passes through our neighborhood. They have voluntarily stated that they intend to make significant improvements to this street in excess of what can be legally required of them. We applaud their willingness to contribute in this way to the quality of our neighborhood. The current and future status of SW 135th Street, south of SW Walnut, is of great concern to all of us in the neighborhood, and we would like to continue to work with the city and the builder to ensure that the improvements will result in a safe and convenient area for us to live, In this regard, we would like to make three specific recommendations to the Planning Commission regarding this section of SW 135th Street. First, we would strongly urge the city to agree to assume maintenance responsibility for this section of SW 135th after the construction improvements are completed. Manumit as the remainder of SW 135th Street, south of SW Scholls Ferry Road and continuing up to SW Bull Mountain Road, will be the property of the city of Tigard, it seems reasonable and sensible for this small section to become city property as well This will ensure that proper maintenance is performed. This is a particular concern to us in the neighborhood during inclement weather as we have seen during the past two weeks. This hill is very slippery, and will require ashes for traction under icing conditions. Since the city will have the responsibility for the rest of the street, acquisition of this short section from SW Walnut south to the new deveIopment will ensure continuity of coverage during such situations, Secondly, we recommend that the builder provide a street with 34 feet of pavement, with a sidewalk on one side, and on-street parking on the opposite side. We bellieve that this configuration best serves the needs of the neighborhood and the new development, in providing a neighborhood street fully capable of aecommodating the traffic through the area, and providing safety for pedestrians using the street as well. Although there was some disagreement on the exact placement of the sidewalk, 1 believe that the eoncensus was that the sidewalk should be on the west side of the etreet. This will be safer for the children who walk down to catch the school bus, and will improve the site distance at the intersection of SW Fern and SW 135th. Thirdly, the members of the neighborhood are all aware of the dangerous conditions which exist at the intersection of SW Fern Street and SW 135th. In snowy or freezing conditions, this intersection becomes so slippery that traffic entering onto SW 135th from SW Fern cannot reliably stop to accommodate cross traffic. Therefore, we request that stop signs be provided at this intersection, on SW Fern traveling east, and on SW 135th traveling north (down the hill). This will aid greatly improve the safety of this corner. Thank you very much for your thoughtful consideration. We welcome this opportunity to express our opinions and concerns about this improvement, and pledge to work closely with the city and developer as this construction proceeds. Yours truly, Larry 'Westerman, on behalf of the SW Fern Street/SW 135th neighborhood STAFF' REPORT TO THE PLANNING COMMISSION FEBRUARY 19, 1990 -- 7 :30 PM TIGARD CITY HALL TOWN HALL 13125 SW PALL BLVD. TIGARD, OREGON 91223 A. PACTS AGENDA ITEM ? qv 1. General. Information CASE: Subdivision S 90 -01, Planned Development PD 90 -01, and Sensitive Lands SL 90 -01. REQUEST: For preliminary plat approval, detailed planned and development approval roval to divide a 39.2 acre parcel into 119 P lots between the sizes of 7,000 and 14,589 square feet. Alsm,; sensitive lands approval to allow the placement of a sanitary sewer line and for possible construction on slopes over 25 percent. COMPREHENSIVE PLAN DESIGNATION: Medium Density Residential ZONING DESIGNATION: R -7 (Residential 7 units per acre) APPLICANT: Burton Engineering 302 Tigard Plaza Tigard, OR 97223 OWNERS: FL io Saito and Yasuhiro Kouzai 1070 NW Murray Road Portland, OR 97229 LOCATION: South of 135th Avenue and Northwest of Benchview and Three ree Mountains Subdivisions, WCTM 2S1 4 tax lot 700. 2 Background Information On July 17, 19890 the 'Tigard City Council approved a request for annexation of the dub jest property and for larded Resolution Number 89- 57 to the Metropolitan Area Boundary Commission for . t0 consideration. The Boundary Commission approved the annexation on August 24, 1989 (Boundary Change Proposal No 2663) . On September 11, 1989, the it Council adopted a change in zoning of the subject ; property from Washington County R-6 to City of Tigard R -7 PD (Residential • 9 y units: per acre, Planned_ development). _... .e �Cit 'to adopt the er dire, The Urban Planning Area Agreement, between the City and Washington County, requires the y p zone which most c losely resembles the existing Washington ngtoY Counter zone REPORT - KOUZAI/BtLRTON 0 90. 01 /PD 90-01/8L 90-Oi ) PAGE 1 for a period of at least one year. This change in zoning was consistent with the agreement. Both the Washington County R-6 and the City of Tigard R-7 zones allow for a 5,000 square foot minimum lot size for single family residences. 3. Vicinite_Information S.W. 135th Avenue extends from the northeast property corner directly north to S.W. Walnut Street. Along the property's northern border lie a number of home sites that generally range in size from one-half to two acres. These residences are located on either side of S.W. Fern Street e which rune east and west with an intersection with S.W. 135th Avenue at its east end. Ltrge undeveloped properties lie to the east, west, and South. Benchview subdivision lies to the southeatet. This subdivision and the land to the east of the property are curreetly within the City of Tigard. The surrounding properties within Washington County are presently zoned R-6 and the parcels within the City of Tigard are zoned R-4.5 (Residential 4.5 units per acre). 4. Site information and Propegelipmeripetign The property to be developed is presently vacant and is situated on the lower portion of Bull Mountain's northern slope. The property is almost entirely wooded. A large ravine, which tuns downhill to the north is located on the west side of the property and the remainder of the parcel slopes down to the northeast and east. The applicant proposes to divide the property into 119 tangle family residential lots. Initially, access will only be provided by a southerly extension of 135th Avenue. This extension is intended to be a minor collector street which will continue up the hill and eventually connect with S.W. Buil Mountain Road. Other local streets within the subdivision will provide access to the propoeed lots as well as abutting properties to the south and west. The large westerly ravine will remain undeveloped at this point, however, the applicant has illustrated a conceptual street alignment which would extend across the ravine to the adjacent property to the west. A Sensitive Lands review is also necessary because of the installation of a Sewer linct along the east side of the western ravine and the poesibility that other construction will occur on-slopea. in excess of 25 percent. The majority of the property has slopes less than 25 percent, however it is possible that a limited amount of public facility and residential construction will occur on slopeS steeper than 25 percent. 5. Ageney and NPO Commentn The Engineering Division has the following comments: The applicant propose° to develop 39.2 ecres of vacant land Which hae recently been annexed into the City. The land JO located on the Northeast STAFF VVPORT KOUZAI/BURTQN (5 90-01/PD 90-01/SL 90-01) PAGE 2 • sidq of Bull. Mountain and is relatively steep with one ravine with very steep aide banks. No public facilities currently exist on tte property. The applicant has submitted a pite plan showing the proposal lot layout and public road, water, sanitary sewer, and storm drainage systems. Findings: 1. The collector 'road system of the Northeast Bull Mountain area is currently being evaluated by the City. A report has been prepared by City staff with several route options for the area This site is affected by one of the routes proposed, the extension of 135th Avenue to Bull Mountain Road. The traffic volume analysis indicates that this route will serve as a neighborhood collector street providing access for the future residents of the immediate area to Bull Mountain Road and to Walnut Street. Through traffic from Bull Mountain Road to Walnut Street is expected to be a small percentage of the total traffic. A direct route from Walnut Street to Bull Mountain Road would encourage more through traffic than an indirect route would. The steep terrain of Bull Mountaiss also prevents a feasible through route without steep grades or impacts to the development of the site Therefore an indirect connection is acceptable for this route. The proposed road system incorporates the indirect minor collector concept into its layout and is acceptable. 2. Direct vehicular access to minor collector streets is ganerally discouraged unless circumstances exist which prevent an altereative access. The proposed street layout proposes access to the upper half of the minor collector street by 19 lots, with ad6.1tional accesses as future development to the south occurs. Traffic volumes are expected to decrease as the road approaches the mid point of the Bull Mountain/Walnut connection. Also alternative access for these lots is not available due to the restrictions of the terrain without impacts to the adjoining property and to the proposed development, therefore the direct access should be allowed. However, since this route will be a minor collector street, it is recommended that additional measures be taken to reduce the impacts to the residendes fronting this street sudh as additional setback requirements for the future homes. 3. Access to the site will be provided by 135th Avenue. Currently, 15th Avenue is an approximately 20 foot wide paved Street, which serves the residential areas of Fern Street and Walnut Street and alao has Borne direct residential acceOses. The pavement was not constructed to local street standards and is under the jurisdiction of Washington County. It's intersection with Walnut Street does not meet current design standards and improvements are recommended to the intersection to improve its safety. A traffic analysis should be provided discussing the projected traffic volumes at the intersection and evaluating the necessary improvments. The improvements should provide a landing area of leSs than 5 percent grade and a 'q'" interSection. STAFF REPORT - KODZAI/BURTON (S 90-01/Pb 90-01/SL 90-01) PAGE 1 • Structural improvements to the exA.sting 135th Avenue should be made since future traffic levels will increase substantially over existing traffic levels. The pavement should receiv. a minimum 2 inch asphaltic concrete overlay and be widened to a minimum of 24 feet. The vertical profile should be evaluated to ensure that any improvements to 135th Avenue will match future improvements. Reconstruction, if the vertical profiles do not meet current standards, should be made by the applicant. Provisions should be made for pedestrian traffic ecng 135th Avenue. As a minimum, a grave/ shoulder with a width of at least 5 feet should be provided on one side of 135th. 4. Sanitary sewer service is proposed to be extended from Hart Street (Franklin Street) up 135th Avenue into the site. Stub-outs ohould be provided along the route to Valnut Street and Fern Street for future extension of the public line. Service should also be extended to the south as shown 'on the submitted plans. The lots which back onto the ravine on the west edge of the site may need to be served along the back eide since they slope away from the street extensiarely. The future extension of this line should be public since it will be serving more than 16 lots. Access for maintenance vehicles and permanent eaeements should be provided for all lines which are outside of the public right-of-way. The nonstruction of the sanitary sewer pipeline within the sensitive land area is necessary to provide service to the lots which border the area Lad are lower than the public street to the eato Therefore, the engineering staff has no objection to the seneitive laude permit. 5. Storm drainage is shown to be collected on site and discharged down 135th Avenue and also into the ravine on the west edge of the site. Since development of the site will result in an increase in the existing runoff, the drainageways should be evaluated downstream to ensure adequate facilities exist. Upgrading the drainageways to avoid impact el downstream may be necessary. The drainageway in the ravine currently passes through private property and across Fern Street. Coordination with the owners of these properties Should be pursued, especially if improvements are necessary to avoid impaate. The drainageway down 135th Avenue currently drains into a swale to the east about halfway down the street. Provisions to upgrade this drainageway or to direct the runoff down 135th AvenUe should be evaluated. 6. Erosion control, as outlined in the Erosion Cantrell Plane Technical Guidance Handbook published by Portland and Washington county, will be an important aspect of construction due to the steepness of the site and the obvious amount of clearing and earthwork Which iii/ be required to develop the site An erosion control plan following these guidelines is required. STAFF REPORT - KOUZAI/BURTON (S 90-01/PD 90-01/SL 90-01) PAGE 4 • • Scott King, a Transportation Planner with the Washington County Land Use and Transportation Department states that the County requires a development, which generates more than 200 trips per day and accesses a County road, to submit a traffic study for County review. The trip generation for this development is 1200 ADT based upon 1TE category 2-10. The applicant shall provide the County with a study prior to final approval. County review of this study may result in further requirement for public improvements. Mt. King also has the following recommendations: A. Prior to final approval and issuance of building permit: 1. Submit a traffic study pursuant to County resolution and order 83-213. CONTACT: Daryl Steffen, County Traffic Analyst at 648- 8761 for questions regarding this study. 2. Sign a waiver not to remonstrate againct the formation of a Local Improvement District or other mechanism to improve and maintain SW 135th Avenue to County standards between the site and SW Walnut Street. The documents required for completion of recommended condition A.2. shall be prepared by the Washington Courty Survey Division and recorded in the Washington County Records Department. 3. Submit 'plans, obtain Engineering Division approval, provide financial assurance, and obtain a facility permit for the following public improvements; a. Provide S.W. 135th Avenue between the site and S.W. Walnut Street with a minimum 22 foot width and wearing surface in life expectancy of not Iesd than five years. b. All improvements required by the County review of the required traffic Study (see recommended condition Al above)- B.

Hal Bergema, Senior Planner, also with the Washington County Land Use and Transportation Department, expressed Department concerns relating to the number of trees that will need to be removed as a rebult of the standard subdivision and the potential impact of the proposed street locati,In on the west side stream corridor and ravine. The Tigard Water District comments that it will require a loop system and a pressure reduction vault and valve system on 135th Avenue. The Tigard Building Division indicates that private Storm drain lineS fflUt STAFP REPORT XOU2AX/BURTON (8 90-01/PD 90-01/SL 90-01) PAGE 5 • be installea on Iota 17 -27, 36-43, 46.56, 66 and 72 -78, 80-89, 93 and 100-- 102, 91 and 108 -112, and 113 -119. The Tualatin Valley Fire and Rescue District indicates that hydrant placement will be coordinated through the Tigard Water District and that plans should be submitted for review and approval to the District. The Tigard School District i adicates that the proposed complex la located within the Mary Woodward Elementary and Fowler Junior High School attendance boundary. This complex along with 20 others now being planned or constructed will generate 163 new students for Nary Woodward Elementary and 71 a udentsa at Fowler Junior Htgh School. The Tigard School District may not be able to accommodate them at Mary Woodward or at Fowler. Prospective occupants should be advised that studenta may be bused to other schools. After the District completes its new middle school in 1992, there should room available at Mary Woodward and Fowler junior Hi g h School fo r these students. Because of the time and cost constraints, it is the District policy that biases generally do not enter subdivisions. It is very important to u® that your design consider space for bus pull out sufficient in size to allow traffic to pass safely without stopping. No other comments have been received. B. FINDINGS AND CONCLUSIONS The relevant approval criteria are Comprehensive Plan Policies 2.1.1, 3.1.1, 3.4.2, 3.5.1, 7.1.2, 7.3.1, 7.4.4, 7.6.1, 8.1.1, 8.1.2, and 8.1.3; the Bull Mountain Commuvnity Plan, and Community Development Code sections 18.54, 18.60, 18.150 and 18.160. Since these plans have been acknowledged, the statewide goals no longer have to be addressed for non- legislative land use applications. The Planning staff concludes that the proposal with moda.ficatione is consistent with the applicable portions of the Tigard Comprehensive Plan based upon the findings noted below. 1. Policy 2.1.1 is satisfied because the Neighborhood Planning Organization Number 3, Community Planning Organization Number 48, 'and the surrounding property owners were given notice of the hearing and an opportunity to comment on the applicant's pr opoeal. 2. Policy 3.1.1 can be aatiefied because the Code allows development of hillsides that are steeper than 25 percent when engineering information is provided which shows that adverse environmental erosion or slope instability will not result The applicant has submitted a general description n of the site but the techniques for mitigating any potential problems related to eteep slopes have not been included. Staff does not anticipate any STAFF REPORT - KOtiZAI /8tiRTON (s 90 -01/Pb 90-01/SL 90-01 ) difficulties, provided that the appropriate construction and erosion control measures are employed. Since m any issues regarding slopes ara � site specific, the staff recommends that methods for maintenance of slope stability and erosion control be submitted for the ' appro ral in conjunction with the public improvement plans mnd building permits with particular attention being paid to grades over 25 percent.; Policy 3.4.2 is satisfied at the present because the proposed) plat does not extend into the large drainageway at the west end of the p roperty. However, the future street extension and ultimate disposition property � ia�Y the future, much ra eition of the has into be described by the applicant.

This plat does not provide for any common open space within the development. Although the lack of common open space is not necessarily in conflict with this policy, it y � preserve r grading and and undoubted) will be more difficult to reserve the the natural scenic values of this property without it The site gr g tree removal plans required in the conditions of approval below shall be reviewed with the intention preserving they natural features of the site to the maximum extent possible. 5 Policies 7.1.2, 7.3.1, 7.4.4 and 7.6.1 are aatisified because adequate water, sewer, and storm drainage facilities, as well as fire protection services are or will be made available to the development. The applicant has indicated that these facilities will be provided within the subdivision as . required by City standards. 6. Policy 8. 1. 1 calls for a safe and efficient street systems that meets current and projected needs. The proposed internal street system satisfies all applicable Code and. Plan street standards. 7. Policy 8.1.2 and 8.1.3 will be satisfied becai*ee the City of Tigard and Washington County have and will be working together to resolve street improvement and location issues involved in this case and the greater 'Bull Mountain area The proposed subdivision street improvem nts will be constructed to City or County construction standards as applicable and will be installed at the developer's expense. Sufficient public right -of -way will be dedicated to the public within the Subdivision_ for these streets. The Planning et.. aff concludes that the proposal its modificatio s consistent sistent w>th the Bull Mountain Community Plan based upon the following findings: 1. The density of the proposed contemplated by the Plan. 1117E square foot minimum lot Size designation. STAFF REPORT KAuzAI /1iuRTON S 00-01/Pb 00.01/SL 00-01) alibdiviaton is within the limits lots will be well above the 6,000 of the former R-6 County' Plan 2. The preservation of trees is viewed ae an important component of the Bull Mountain Plan's strategy for preserving wildlife habatat and related aesthetic benefits. This property is entirely within a significant natural area as identified in the :elan. These areas are considered to be important due to their natural condition as well as ecologic, scientific, and educational value The proposed preliminary plat application does not include a plan for the preservation of trees on the property. Such a plan provided by a approved prior to removal of trees on the r be submitted property or the approval of the final plat. An assessment of the street extension to the west and its impact upon the western ravine and stream should be accomplished prior to approval of the final plat. 3. The property is also within Area of Special Concern No 3.. This designation has been 'applied because of the County's expressed desire to evaluate significant natural areas on the north slope of Bull Mountain and to consider the possible aquieition of land as permanent open space. This stud y has not been conducted by the de's unty or the City. The Plan text does indicate that in the interim, lopment may occur in a manner consistent with the Plan and applicable cod provisions. General design elements of the Plan include the design of minor collector streets which will not encourage through traffic, minimize the amount of land and vegetation disturbance, limit the removal of trees over six inches in diameter to no more than 50 percent, and the protect stream corridors. As discussed above in the Engineering Division comments, the minor collector street system is being designed primarily to serve the p rather : through traffic. future development on Dull Mountain than Detailed plans shall be required as a condition of approval to show that minimum of 50 percent of the tree will be preerved and that land disturbance, particularly in the ravine area, will be kept to a minimum. .The Planning staff concludes that the proposal, with. modification IS consistent with applicable portions of the Tigard Community Development code based Upon the findings noted below: ;. Chapter 10.52 of the Code ie satisfied because the proposal does the density requirement of the R -7 zone. 2 Cha p ter 18.92 is ®akldfied because the proposed density IS consi stent with Code requirements. Chu apter 18.80 is satisfied because . a p r. po sa8is Co1S dts nt with the e p rp requirements p er: pertaining to plarne developments. Planned dew lopmnte are intended to be used it meet', STAFF REPORT -- KOUZ I /BURTON (S 90 -01/P0 90- -01/SL 90 -01) undeveloped aroas such as this to better protect amenities on the site Although this section of the Code encourages the provision of common open space areas through the application of flexible development standards, common areas are not required by the Code. 4. Chapter 18.84 covers sensitive lands issues within drainageways and slopes over 25 percent. The drainageway on the property will be avoided however, as noted earlier, the future use of this section of the property must be evaluated further. Although slopes of over 25 paircent will generally be avoided by this project, it is possible that some of the homesites will be located on slopes over 25 percent. Provided that grading, construction, and erosion controls are approved and monitored by the Engineering and Building Inspection Divisions for this development, the provisions of this chapter will be met. 5. Chapter 18.60 of the Code is satisfied because the proposal does meet the requirements set forth for the submission and approval of a preliminary subdivision plat. 6. Chapter 18.150 of the Code prohibits the unnecessary removal of trees over six inches in diameter. As noted abova, a tree preservation report prepared by a qualified arborist shall be required prior to the commencement of any construction on the iten 7° Chapter 18.164 of the Code will be satisfied during the approval process for the final plat. C.

All three phases were analyzed in this report In discussing the project with Washington County's Department of Land Use and Transportation, and following their requirements for developmental °'access' reports`' , the project scope was defined Impacts to the existing vicinity roads including access location, 'traffic safety, feasibility, operatir)n, trip generation, distribution, traffic flow, sight distance, turning lanes, and signalization are analyzed in this study. The County indicated it would be necessary to include year 2005 "tin- process" future traffic i n the study Background data for the future traffic was furnished by the County for Bull Mountain Road and the Walnut Street at SW 121st Avenue intersection. The results of this analysis indicate the project will not adversely impact any roads, streets, or intersections. These f i nd i ngs are based on the current street conditions and several proposed roadway improvement projects identified by the agencies.

SITE .DESCRIPTION AN, D RCA ©S. The proposed Bull Mountain Summit View Estates development w i l l consist of 486 single family units constructed on undeveloped land Access to the development w i l l occur directly onto Bull Mountain Road from the south side and SW 135th Avenue from the north side. SoUthwest 135th Avenue w i l l be extended to the south and a number of new streets constructed within the development to provide for traffic circulation and access The access to Bu l `R Mountain Road will be a n nnect i o% occurring at 1 39th Avenue (existing south side street) or near this location. 1 In order to evaluate the total traffic impacts for this development, it was necessary to analyze both the AM and Pm peak hour traffic conditions including the site generated volumes. Trip generation for both conditions is discussed later in The report. Existing streets in the area which will be imps e,ed by the site traffic include Su l l Mountain Road, SW 135th Avenue, Pacific Highway 99, Beef Bend Road, Scholls Ferry Road, SW 121st Avenue, and Walnut Street. After calculating the amount of generated traffic and the anticipated distribution patterns, it was determined that streets and intersections beyond those listed above would have less than a 10% traffic impact. Therefore, it was not necessary to analyze other streets beyond these limits. Near the proposed s,te access on Bull Mountain Road, the ex i $,l i ng configuration of Bull Mountain Road consists of a two lane two -way road. There is 22 feet of paved surface (two 11 foot wide lanes) with two to four foot wide gravel shoulders. The posted speed is 40 miles per hour. Intersection sight distance at SW 139th was recorded at 510 feet west of 139th and 550 feet east of 139th. Speed surveys reported by the County revealed the 85th percentile to be 46 to 50 miles per hour along Bu l l Mountain Road. Therefore the existing sight distance to/from the existing intersection po i nt at 139th Avenue is adequate. There are vertical roadfiay turves to the east and west of 139th Avenue oh Bull Mountain Road whin control the sight .d i stance Due to the exis'4ing topography and roadway grades, locating the proposed access point east dr west of 139th Avenue would J 8 1 1 available v i s i b i l i t y . Also the County's standard for locating "opposite T- shaped" intersections next to each other is 365 feet. ro This distance stance i s bayed on the minimum lmum 1 eft turn stor age distance •of 100 f eut for each intersection and a median transition length of 165 feet. Since the sight distance and would not meet the standards unless 139th Avenue 139th Avenue. The other access for the proposed development will be located onto SW 135th Avenue when it is extended from om its present location just south of Fern Street. Southwest 135th Avenue then intersects with Walnut Street where it is controlled by a stop sign. Walnut Street is a two lane street posted at 35 to 40 miles per hour as passes through a residential neighborhood. the paved width is 24 feet. left turn median storage length the new access is located at it is will be necessary to locate the new access at Street and intersection characteristics for other critical locations were also reviewed in making the study. The data was recorded and applied in performing the capacity analyses and •recommendations. • TRAFF i C FLOC►'; ANALYS I S In order •to obtain updated traffic volume-data.and perform e the traffic flow aha l ys i s y mahual turning movemer t counts were performed at several i ntersect i pans. 16 the study area, ..Manual counts were de • t ors weekday from 7.00 AO to 8 0 30 AO and 4 $0 Pied to •was •recorded i n 15 mi huts intervals and summarized •peek •_hour •determi nat i ore . •Generally..

Th intersections counted included Pacific Highway 9" at Walnut at Bull Mountain Road and Bull Mountain Road at SW 139th Avenue. Beef Bend Road at Scho 1 1 s Ferry Road was also counted Previous studies provided 1990 count data on 135th Avenue at Scholls Ferry Road and Walnut. Southwest 121st Avenue at Walnut was also previously counted. Traffic flow maps were prepared showing the traffic count data (rounded to the ,nearest five vehicles) and turn movements for the peak hour conditions. Flow distribution for the site generated traffic was proportioned as approx innate l y 25% tO/f torn the north, 27% to /from the east, 11% to /from the south, and the remaining 37% within the immediate zone as defined by Metro's 1980 census tracts. The trip distribution data based on year 2005 p � � projections was furnished by Washington County, Existing traffic count data Was also considered in assigning the traffic flows.

VEHICULAR i U GENERATION Vehicular trip generation rates from the 1987 I.T.E. Tr i p Generation Manual were applied in performing the analysis. The following values were applied in assigning the peak hour (AM & PM) generated traffic. A total of 4510 trip ends will occur over a 24 hour weekday period. Approximately 50% will be entering trips and 50% will be departing trips each weekday. ,Land Use 486 $F Homes PROJECTED TRIP GENERATION AM Peak Enter Exit Total. 90 250 340 Enter. 300 PM Peak_ plod* Tr i pe Exit Total, 180 480 The regression equat i ores published i n the 1 981 1 . 1 ' . .

The intersections rsect,e+ns were analyzed for existing, existing with site traffic, and total site (in- process, year 2005) conditions. A computer program for non- signalized intersections based on the latest Highway Capacity Manual (1985) and vehicular delay method was used All printouts are attached in the appendix.

Level "D" will result in longer delays but is acceptable for peak conditions. Level °'E" represents very long delays and should be avoided or minirized if possible, From a capacity and L.O.S. standpoint, the intersections studied will not experience major level of service changes providing the improvements identified above are implemented. TRAFFIC.. SIGNAL WARRANTS Traffic signal warrants as prescribed in the Manual On Uniform Traffic Control l Devices were determined for the uns i gna l i zed intersections of SW 139th Avenue at Bull Mountain Road and SW 135th Avenue at Walnut Street. The p = ak hour warrant (14o 11) was determined for both the AM and PM peak hours (present with site traffic and Year 2005) and found to not meet signal warrant conditions. The case for less than 10 000 population and speed over 40 miles per hour was applied. Therefore, signals should not be considered. The warrant curves for these conditions are contained in the appendix. The intersection of Scholls Ferry Road and SW Beef presently is a stop controlled intersection with a stop sign Bend Roar . Due to the existing peak hour traffic f i' � yo l umes ( both AM and PM) it meets the peak hour traffic signal warrant. I n discussions with 0 D.0.T. it has been acknowledged that the inter- - section is in need of improvements including possible s igna 1 i gat i can However, due to other prioritized projects the 'schedule to construct any improvements at this location is indefinite. TRAP E C LANE F3ggU I REMELIIS Bull Mountain Road w i l l adequately function from a traffic safety and capacity standpoint with the existing 6treet configuration. However, at the intersection with the new site access, separate turn lanes will be required. For the eastbound to northbound left movement, a median lane with 75 feet storage w i l l be required to handle the total traffic (with 'fin -- process traffic conditions. There w i l l also be a westbound right turn lane and school bus stop (west side of intersection) on Bull Mountain Road. The new southbound approach at SW 139th Avenue will require one inbound (northbound) lane and two outbound (southbound) These lanes should be marked for a distance of 100 feet to separate left and right turns to Bull Mountain Road On the north side of the development, traffic w i l l access the existing street system along SW 135th Avenue south of Walnut Street The new street connection needs to be two lanes wide With one inbound and one outbound lane. other lane improvements and recommendations were identified i n the capacity analysis section. SUMMARYAN RECOMMENDATIONS From a traffic engineering standpoint the development can adequately function based on the data ana l yzed . There should be no adverse impacts to Bull Mountain Road: SW 1 35th Avenue, Walnut Street, or other vicinity streets . if the recommendations proposed in his report are adopted and implemented. Based on the projected traffic volumes, and Year 2005, Bull Mountain Road at SW 139th Avenue w i l l experience L.O.S. "B " conditions J ra the peak hours under the existing and site tra ff i c conditions. No signal warrants aro met. It is recommended that the new site access provide for separate left and right turn lanes (southbound) leaving the site and one inbound (northbound) lane An eastbound to northbound left turn lane (storage length of 75 feet) and westbound to northbound right turn lane will also be necessary on Bull tiounta i n. Road at the new site access. Southwest 135th Avenue at walnut Street wi l l operate at service level "A" under the existing plus site traffic conditions. The only recommendation to improve this intersection i s to widen the existing turning radius ih the southeast corner to about 30 feet, Considering the anticipated traffic volumes associated with the development, it is essential from a traffic operational and safety standpoint that certain improvements be made. The following elements should also be undertaken in conjunction with the development, o Maintenance of the existing and adetluate sight distance along all existing and proposed streets and the Project site frontages is essential. Obstruction by landscaping, parking, buildings, or other objects would be unsafe. It will be necessary to implement standard traffic control devices, including pavement markings and signing as per County standards and the Manual ` On Uniform Traffic Control Devices No parking should be allowed along Bull Mountain Road, SW 135th Averbfe, or along the new site street approaches near these intersections.

Market Street is , two -lane collector, and Jones Sti eet is a two-lane ^i,►l street serving a residential development. It is controlled with a sToP sign There is no widening in the vcinity of the intersection, and corner radii are 20 ft, The intersection is depicted in Figure 103 -8. Residents of the area have complained that there is substantial delay experienced in the late afternoon turning ,tight into Market Street. They claim that this iS due to the reed for right and left turners to share a lane, and have requested that a right-turn- only lane be provided. 2. Solution --The T- intersection Worksheet will be used for summarizing and organizing computations concerning this proi.ilein. The problem is to evaluate whether or not the re- quoted improvement will achieve any reasonable reduction in the delay experienced by local residents traversing this location, The computations on the worksheet (Figure 10 -8) Are de- scribed and discussed below: LL • 6') i '(d) 2. Since no classification of vehicles is given, nor is any grade present, volumes 4, 7, and 9 (which must be adjusted) are by 1.1 to reflect normal traffic compasation._T l.e �"-gr9justri Volumes are entered on the upper-right diagram for easy reference in later computational steps. 3. The ItT from the minor street is the first movement con- sidered, The conflicting volume is computed as one -half the major street right -turn volume, plus the through volume with which the minor street RT will merge. The conflicting traffic is thus found to be 270 vph. The dritical gap is selected from Table .l0 for an RT from minor sttreet, tWo lan sonthe major street, and prevailing speed of 30 mph. The critical gap be 5,5 Sec: There are no conditions which would allow adjusting this critical gap. 1, Existing peak hour volumes for the afternoon period were collected, and are summarized as indicated on the upper -left diagram.
