LAWRASON,Jr. "`City Engineer Councilmember JOHN V. GILLESPIE LILLIAN KELLERMAN Chief of Police City Clerk RICHARD T. HARE City Treasurer MEMORANDUM TO: The Honorable City Council FROM: Patrick J. Richards, Director of Community Development DATE: December 12, 1990 (CC Meeting of 12-19-90) SUBJECT: VESTING TENTATIVE TRACT MAP NO. 4620 - JBH DEVELOPMENT COMPANY Background On December 3, 1990, the Planning Commission adopted a resolution recommending conditional approval of Vesting Tentative Tract Map No. 4620 . The Planning Commission's resolution and recommended conditions of approval are attached. The Planning Commission staff reports and project exhibits were provided to the City Council with the December 5, 1990, agenda packet. Tract No. 4620 was originally scheduled for the Council 's December 5 meeting but was continued to allow adequate time for Planning Commission review. Discussion At the Planning Commission's December 3 meeting, the Commission voted to add a condition of approval (No. 119) which requires the project CC&R's to include language which encourages the homeowners association to cooperate to develop a public equestrian trail system. In addition to the equestrian trail issue, there were two outstanding access road issues discussed by the Planning Commission at their December 3 meeting. Staff was requested to contact the Fire Department and clarify the following: 1) Would a 20-foot paved width be acceptable for Aspen Hills Drive instead of the 32- foot width that is required by Condition No. 33; and 2) Can Knox boxes be required on both sides of the proposed project gate at Aspen Hills Drive to restrict access to emergency use only for Tract No. 4620 . Staff discussed the Planning Commission's concerns with Shonna Perry, Ventura County Fire Protection Officer, on December 4, 1990 . Officer Perry informed staff that the Fire Department recommends 799 Moorpark Avenue Moorpark, California 93021 (805) 529-6864 The Honorable City Council December 12, 1990 Page 2 that Aspen Hills Drive be a full secondary access for Tract No. 4620, consistent with Fire Department requirements. However, they have no objection to a requirement for a Knox box lock to discourage entrance into the Tract No. 4620 subdivision if vehicles would be allowed to exit that subdivision through use of an automated system which allows the gate to be opened when a vehicle drives over a pad installed in the road. This type of gate design would allow residents living in the Tract No. 4620 subdivision to exit but not enter their private community via Aspen Hills Drive. In regard to the recommended width of Aspen Hills Drive, the Fire Department recommends that the minimum acceptable width should be 24 feet of pavement with 4-foot graded shoulders. The City Engineer's Office concurs with the Fire Department's recommendation that Aspen Hills Drive remain as a secondary access . However, they do not recommend a minimum width of 24 feet of pavement unless Aspen Hills Drive will serve only as an emergency access . If Aspen Hills Drive is to act as a partial or full secondary access for Tract No. 4620, the City Engineer's Office is recommending that the minimum width of the paved road should be 28 feet with 4-foot graded shoulders . Conditions Nos . 33 and 58 will need to be rewritten and the typical section on the map will need to be revised if the Council concurs that the required width of Aspen Hills Drive should be less than 32 feet. In addition, if Aspen Hills Drive is to serve as either a full or partial secondary access for the proposed project, a condition of approval should be added which requires Tract No. 4620 residents to share maintenance responsibility for that road with other property owners who obtain access to their property from Aspen Hills Drive. Several of the property owners who currently maintain this private road testified at the Commission's December 3 public hearing that they would prefer restriction of Tract No. 4620 access onto Aspen Hills Drive to emergency use only. Recommendation 1. Open the public hearing and accept public testimony. 2 . Review project in regard to Land Use Element hillside protection policies . 3 . Direct staff as deemed appropriate in regard to revising conditions of approval related to width, use, and maintenance of Aspen Hills Drive. 4 . Review and approve the Negative Declaration. 5 . Review and approve the Mitigation Monitoring Program. The Honorable City Council December 12, 1990 Page 3 6 . Make the appropriate findings including General Plan consistency (see pages 11 and 12 of November 9, 1990, Planning Commission staff report) . 7 . Direct staff to prepare a resolution approving Vesting Tentative Tract Map no. 4620 based on the findings and the proposed conditions of approval.
