6A - Site Review # SI-2000-1, amendment to approved site plan for Foothills Community ParkCITY OF BOULDER PLANNING BOARD AGENDA ITEM MEETING DATE: Apri16, 2000 (Agenda Item Preparation Date: March 23, 2000) AGENDA TITLE: Public hearing and consideration of Site Review, #SI-2000-1, an amendment to the approved site plan for the Foothills Community Park (formerly known as the North Boulder Community Park) located on Cherry Avenue, north of Locust Avenue and west of Rosewood Avenue. The proposal is to remove the requirement that secondary vehicular access be provided prior to beginning construction of Phase II (north hal fl of the Park. Applicant/Owner: City of Boulder Department of Parks and Recreation REQUESTING DEPARTMENT: Planning Department Peter Pollock, Planning Director Bob Cole, Director of Project Review Don Durso, Presenter OVERVIEW: The Planning Board is being asked to consider an amendment to the approved site review (SI#97-15) approving the Foothills Community Park. This amendment would allow the City of Boulder's Parks Department to proceed with construction of Phase II of the Park without providing secondary vehicular access to the Park. Emergency access would still be required prior to completing and opening Phase II to the public. Staff is recommending approval of this request. s:\plan\pb-items~nemos\ddfpark.pbm AGENDA ITEM #~% Pa e 1 STATISTICS: Project Name: Proposal: Location: Size: Zoning: BVCP Map: Variations: KEY ISSUES: Foothills Community Park, #SI-2000-1 Proposal to eliminate the requirement that secondary vehicular access be constructed prior to beginning construction on Phase II of the Park. North of Locust Avenue, west of Rosewood Avenue and east of the foothills +/- 69 acres P-E (Public - Established) Urban and Other Parks Area I None requested. 1. Is the existing access to the North Boulder Community Park and the Foothills Community Housing development sufficient to accommodate anticipated traffic demands without secondary vehicular access? 2. Is it reasonable that construction of Phase II of the Park be allowed to begin without secondary emergency access, as long as secondary emergency access is available prior to the opening of Phase II? BACKGROUND: The North Boulder Community Park (now called the Foothills Community Park, and hereinafter called "Park") was purchased by the City in 1985 and is located near the northwest corner of the City of Boulder. It was annexed to the City in 1990. The 69 acre site abuts City of Boulder Open Space on the west and north, a low density residential area to the south, the Foothills Housing Community neighborhood to the east, and Fourmile Canyon Creek to the north (see Vicinity Map, Attachment A). The North Boulder Community Park Site Review, #SI-97-15, was heard before Planning Board on February 5, 1998, and approved 7-0. Among the conditions of approval was condition number 9, which required that an extension of Rosewood Avenue or another street providing s:\plan\pb-itemsimemos\ddfpark.pbm AGENDA ITEM #~i~ Page 2 adequate secondarv vehicular and secondarv emergency access to the Park be constructed and accepted by the City of Boulder prior to any development north of Cherry Street (phase II of the Park) (see Planning Board Notice of Disposition, condition #9, Attachment B). Primary access is already available from Broadway via Violet Avenue, north to l Oth Street, west to Cherry Avenue. Emergency access to the south end of the Park is available along Union Avenue to 6th Street (Attachment A). Secondary vehicular access was required for two reasons: 1. anticipated traffic volumes for the Park and the Foothills Housing Community and; 2. connectivity, based upon the North Boulder Subcommunity Plan (Attachment F). It was anticipated that the City of Boulder Housing Authority's Foothills Housing Community ("Foothills Housing") would be under construction, and that an additional vehicular access to and from both the Foothills Housing and the Park sites would be available along the extension of Rosewood Avenue south of Four Mile Creek. However, since the 1998 Planning Board approval, the City embarked upon a major flood study of Fourmile Canyon Creek, which indicates that its floodplain extended farther than the current regulatory maps indicate, impacting development along the creek, including the Foothills Housing property. The full study of Fourmile Canyon Creek is currently underway. In response to this study, the Foothills Housing site plan was reduced from 130 to 75 residential units, and the flood issue has caused a delay in the construction of roads accessing the north edge of the Foothills Housing site as well as the Park site. Because of the reduction of units within the Foothills Housing site, no secondary vehicular access was required for that project at the time of the Planning Board approval (see Traffic Study, Attachment D). However, as a part of the Foothills Housing site plan, emergency access from Broadway to the north end of the site via an access through the Ponderosa Mobile Home Park, serving both the Foothills Housing site and the Park, was required as shown on the Foothills Housing Site Plan (Attachment E). The completion of the flood study will determine when or if the north access roads adjacent to Fourmile Canyon Creek will be able to be constructed, and whether it is possible to increase the number of housing units at the Foothills Housing site. The south half of the Park (Phase I) is now close to completion. Vehicular access to Phase I of the park site is taken from Broadway to Violet, to l Oth Street to Cherry Avenue. The Parks Department now wishes to begin Phase II during the year 2000. Construction of Phase II of the Park is anticipated to occur over a two to three year period, and would consist of improvements in the north half of the site, including two ballfields, tennis, basketball, volleyball and handball courts, shelters, and a second parking lot. s:\plan\pb-items~r-emos\ddfpark.pbm AGENDA ITEM #~~ Page 3 ANALYSIS: 1. Is the existing access to the North Boulder Community Park and the Foothills Community Housing development sufficient to accommodate anticipated traffic demands without secondary vehicular access? When the Park project was approved, it was anticipated that the Foothills Housing project would include 130 units, and that it would be under construction by the time construction of Phase II of the Park began. Under that scenario, it was believed that active use of the recreational areas of the park would be unsafe without secondary emergency access and that an additional vehicular access would be necessary to accommodate the traffic volumes created by opening Phase II of the Park and the 130 residential units. However, based upon the reduced residential units at the Foothills Housing site and the revised traffic analysis (Attachment D), staff has concluded (and had previously concluded, at the time the Foothills Housing Site Review was approved without secondary vehicular access) that having one primary vehicular access (Broadway to Violet to Cherry) will result in acceptable traffic conditions. The North Boulder Subcommunity Plan (NBSP) shows multiple vehicular connections to this area, and these connections are still desirable (Attachment F). However, because of circumstances that were not anticipated at the time the NBSP was adopted (floodplain issues) the future of these connections is uncertain. In the future, if expansion of the Foothill Housing site becomes possible, staff is requiring that the Parks Department and the Housing Authority jointly build an additional access, subject to the review and approval of the Planning and Public Works Departments. This requirement is similar to that which was required at the time the Foothills Housing Authority Site Review was approved (Planning Board Notice of Disposition, condition #8, Attachment C). 2. Is it reasonable that construction of Phase II of the Park be allowed to begin without secondary emergency access, as long as secondary emergency access is available prior to the opening of Phase II? Moving forward with construction of the Foothills Housing project and Phase II of the Park will not increase the need for secondary emergency access. Currently, emergency access is available to the south end of the Park from Broadway via Violet Avenue to Cherry Street, and also from Broadway via Union Avenue to 6th Street. The need for a secondary emergency access will not arise until such time as the Park or the Foothills Housing project are completed and opened. Therefore, secondary emergency access will still be required prior to completion and opening of the Park or any of the housing units at the Foothills Housing site, in the location indicated on the Foothills Housing Site Plan (Attachment E). s:\plan\pb-items~nemos\ddfpark.pbm AGENDA ITEM # lC~r7 Page 4 PUBLIC COMMENT AND PROCESS: Upon receipt of the application, notice regarding the proposed Site Review was provided to abutting property owners within 600 feet of the subject property, and a sign was posted on the property indicating an application had been received and to contact the Planning Department for additional information. Notice of the Planning Board agenda was advertised in the Dailv Camera. No public inquiry or contact has been received regarding this project. STAFF RECOMMENDATION: Staff recommends that Planning Board approve the amendment to the Foothills Community Park Site Review, #SI-2000-1, adopting the staff inemorandum and the attached Site Review Criteria Checklist as findings of the Board, subject to the following conditions: Amended condition #9: Prior to the completion, opening, or use of Phase II (the north half of the Park north of Cherry Street), the applicant shall construct a secondary emergency access to the Park, with the final details, including size, location, subject to the review, approval and acceptance by the City of Boulder's Planning and Public Works Departments. New condition #10: The applicant agrees to participate in the construction of the extension of Rosewood Avenue or another street mutually agreed upon between the City of Boulder's Department of Parks and Recreation, the City, and the Housing Authority, providing adequate secondary vehicular access. The applicant shall be responsible for its pro-rata share of the cost of construction, including but not limited to, paving, road base, curb and gutter, sidewalks, bicycle and pedestrian connections, landscaping and drainage improvements, and shall cooperate with the City in the implementation of the street plan as set forth in the North Boulder Subcommunity Plan.

Condition #10 (new): The applicant shall agree to participate in the construction of the extension of Rosewood Avenue or another street providing adequate secondary vehicular access to Broadway. The applicant shall be responsible for their pro rata share of the cost of construction, including but not limited to paving, roadbase, curb and gutter, sidewalks, bicycle and pedestrian connections, landscaping and drainage improvements. Background• In February 1998, the City of Boulder Planning Board approved the Site Review for Foothills Community Park (formerly North Boulder Community Park). Parks and Recreation proceeded with construction of the south half of the park, which is now close to completion and is accessed by Violet ancl Cherry streets. In accordance with condition #9 of the Notice of Disposition (issued in 1998) construction of the north half of the park cannot move forward before roadway access from the north (Rosewood or Yarmouth) is constructed and accepted by the City of Boulder. Since 1998, the City embarked on a major flood study of Four Mile Canyon Creek. As a result of the flooding issue, the proposed plan for the adjacent Foothills Housing Project was revised. In order to insure there is no change to the historical condition of the flood water at the downstream properry line the housing project was reduced in size from 130 units to 75 units. In addition, the flooding issue has caused a delay in the construction of roads accessing the north edge of the housing project and the park. Further flood studies will need to be completed before it is determined when, or if, the north access roads adjacent to Four Mile Canyon Creek will be constructed. As a part of the Foothills Housing Project, secondary emergency access from Broadway to the north end of the site, serving both the housing project and the park, has been , ~v!~~~~ It~rr~ # --~~,_ F~'~r~ i _~L- approved through the site review process. A revised Traffic Study was prepared by Transplan Associates in September 1999 to evaluate the following: 1. Traffic projections for the housing project (75 units). 2. Park traffic projections at buildout. 3. The feasibility of combining both housing and park traffic onto the Violet Avenue / Cherry Avenue access. The Traffic Study concludes that the Violet / Cherry access is adequate to comfortably accommodate both the housing and park traffic. Analvsis• The revision to the Condition of Auproval #9 and the addition of Condition of Ap~roval #10 are requested in order to allow the construction of the north half of the community park to move forward. Due to flooding issues associated with Four Mile Canyon Creek, timing of the construction of Rosewood Avenue or another street providing secondary roadway access to the north side of the park, has not been identified. The revised Traf~ic Study prepared by Transplan Associates indicates that the existing Violet Avenue / Cherry Avenue roadway access to the park is adequate to accommodate the anticipated traffic. Through Condition #10, Parks and Recreation agrees to participate in the construction of Rosewood, or another street providing secondary vehicular access to Broadway. ,L~~•Eiva ftGiii ~ - -~!!7 _. f~~!~~ {, ~~
