2. Street Names - Developer shr,ll submi¢ for approval by City Engineer new n<amea for tiloae streets designated on the Tentative Map as Blueberrry Court, Blueberry Road and Orange Way, and R~.dgevale sad Cxestline Way shall be changed to Ridge<rale Circle e,id Creatlire.Circla. 3. Structuxal Design of Streets - (a) The aubgrade for all streets shall be compacted to a depth of 12 inches if this is det_med necessary by the City Engineer or the developer's Soil Engineer. (b) The pavement sections shall be satisfactory to the City Engineer and the developer's Soil Engines. 4. Specifications and Standard Details - In accordance with Section 8.01 of Ord. No. 358, it ie requested that the City Engineer be authorized to modity the City's existing Standard Specifications and Details in applying them to this subdivision in order to allow for modern materials, methods, and design criteria as may be required. Some specific recommendations for such modifies tiona are as follows: (a) Specifications for sewer and water pipe should be modified to allow newer type joints. (b) Specifications for street name signs should be modified to require white reflectorized letters, block numbers and arrows on green coated aluminum sheeting as previously approved by the Planning Commission and City Council. (c) Reference should be made to the 19G0 Standard Specifications of the State Division of Highways, rather than the 1954 edition, particularly with reference to roadway materials. 5. Sanitary Sewer System - In the absence of a planned street pattern showing a street north of and parallel to Valley Avenue, a 10" sanitary sewer should be provided for in Valley Avenue in accordance with the sanitary sewer study made prior to the approval of Final Map, Tract 2591, or substitute a paral- lel system which will accomplish the same for sewer and water. Any sanitary sewer that ie constructed in a side yard or rear yard easement shall have a protective redwood plank covering per City standards. Final approval of the sanitary sewer system should be withheld until the developer has submitted engineering calculations and has demonstrated to the satisfaction of the City Engineer that the proposed system is ade- quate for the service area and generally meets the long-range requirements for sanitary sewer system in this area. 6. Water Supply and Distribution System - Long-range plane call for at least a 12" water main in Valley Avenue which should be provided for at this time. This would be in line with the Water District's attempt to reserve capacity in the 16" Black Avenue line for use by outlying areas. Final approval should be withheld until the developer has submitted engineering calculations and has demonstrated to the satisfaction of the City Engineer that the proposed system meets the requirements of this development and the City's long-range plena. 7. Storm Drainage System - The storm drainage Eystem Ehall be designed to pro- vide capacity for all upstream tributary areas, these areas being treated as though fully improved, as required in Article 9.01 (2) of Ordinance No. 358. If a portion of the drainage is planned to be touted across land to be developed under a separate tentative map, a master storm drainage plan of this future development shall be submitted to the City Engineer for study anal consideration. A public service easement should be provided from the no~thweatern property corner of the Rruae property to Valley Avenue and from Valley Avenue to the existing drainage ditch. Final approval should be c.i.thheld until the developer has submitted ec:L,ine~ring calculations and has demonstrated to the Eatiafaetion of the City Engineer that the proposf;u system fully meets fihe requirements of thin development and all upstream areas tributary to this development. 8. ELecCri~ Rower Distribution, ."street :..fighting an3 Te+.ehone Service Systems - In secs: dance r;ith Article £, Orciirstue 2:0. 358, the Planning Comm+asion moat aneci.fy the method nF. i.u<t:-llatian of pub'.ic utilities at the time of apprcv l of the Tentativ± ?Rep. It is rF:commend~zd that streamlined under- ground systems be u2ed in tYds develop~ert. The City has not been able to determine whether or not P.G. & E, will need power distribution lines on Valley Avenue as they did on Black Avenue. The Planning Commission should rererve the right to require full underground on r.:iese distribution lines in the future, if the modified or streamlined system cannot be installed.
