Water Sunoly and Distribution System - Minor changes in pipe sizes have been made on Exhibit "A". In addition it is recommended that final approval be withheld until the City has prepared (in cooperation with the Water District) an overall master plan for water storage and di~tri- bution. The preparation of such a plan has been authorized by the City. It is anticipated that only the loc tion of the proposed storage tank might be affected by this plan and possibly the sizing of some supplq mains. Each phase of the development of this total tentative map would be allowed to proceed as shown if the master plan were not ready at the time of approval of final Plana. 9. Sewase Collection Svatem - It is recommended that all curved sewer lines have a minim radiae of 200 feet. 10. Fire Hydrants - It is recommended that fire hydrants be located as shown on Exhibit '9". 11. Electric Power Distribution and Street Liahtina Svstema - In accordance with Article 8, Ord. No. 358, the Planning Commission must specify the method of inatallatioa of public utilities at the time of approval of the tentative map. At the present time an underground or "modified" underground system does not appear to be economically feasible, although it is within the Commission's jurisdiction to judge whether the coats can be justified for the benefits to ba gained. Both the developer and P.G. & E, are expected to be repxeaented at the meeting of June 12, and will undoubtedly have comments to make on the various methods of instal, lation. This office has no specific recommendation to make at this time other than to suggest that a combination of systems might be con- sidered with the break point along the creek extending from Hillview Ave. easterly to and along Zinfandel Drive. A "modified" system may be economical north of this line with some rear yard around-the com- mercial, and possibly a standard street system south of this line. 12, Easements a.
