17. Interim measures for achieving the intent of the recommenda- tions of the soils and geologic report following street im- provements but prior to house construction shall be developed by the project's engineering geologists/soils engineers for review and approval by the City at the tentative map stage. 18. Prior to filing the tentative map, a preliminary utility plan shall be designed which shows the nature and extent of damage to native vegetation required to install and provide mainte- nance to utilities. This utility plan shall be designed to minimize damage to native vegetation. The final improvement plan for storm drainage and subdrains shall indicate how natural watering of native species will be maintained while meeting the dewatering requirements of the soils engineering report; these plans shall be subject to the approval of the City Engineer. 19. Geologic/soils studies investigating the potential hazard to the project of off-site mud flows shall be prepared to the satisfaction of the Planning Director prior to filing a final map. Any remedial work to be done on the City's property (Bernal Park) shall be done, if authorized by the City, and at the developer's expense. If authorization to remedy the hazard is not given, the project shall be redesigned, to the satisfaction of the Planning Director, to remove dwellings from the potentially hazardous area. 20. Final design of the recreation area/clubhouse shall be subject to review and approval by the Design Review Board. 21. The private, on-site streets shall be constructed as shown on the cross-sections of Exhibit 11 of the final development plans, except the minimum street width shall be 29 feet or as otherwise approved by the City Engineer. These streets shall be maintained by the property owners. Streets shall allow parking on only one side, and shall be signed to allow City enforcement, if necessary. 22. Unless otherwise approved by the City Engineer, the minimum radius of all cul-de-sac bulbs shall be 45 feet. 23. The proposed paved drainage ditches shall be constructed of concrete. 24. The length of the vertical curves on project streets shall be designed to the satisfaction of the City Engineer, particularly in those areas where the street grade is over 10 percent.
