include the fOllowing: a. A geotechnical evaluation shall be performed on each lot or group of lots with similar subsurface conditions after subdivision grading is completed and prior to issuance of building permits. Corrosivity and expansion potential of the native material and fill shall be evaluated by the geotechnical engineer along with the subsurface conditions observed during grading. The geotechnical engineer shall provide building foundation design, soil preparation, and fine grading recommendations which are appropriate for the on-site soil and geologic conditions observed after subdivision grading is completed. b. The surface drainage system on each lot shall be designed by a qualified civil engineer and shall be compatible with the subdivision's drainage system. The following items shall be incorporated into each lot's surface drainage system, unless otherwise allowed for custom lots: All building pads shall be rough graded with a 2% slope. All roof downspouts shall be connected to a solid pipe collector system which discharges directly to a city storm main or street gutter. Building pads shall be finished graded with a 2% slope for a minimum of 4' away from the building foundations. site drainage shall be directed toward the street or storm drain system in accordance with section 2907 (d) 5 of the Uniform Building Code. The crawl space of each house shall be provided with a drainage system which will discharge all water which might enter the crawl space directly to a City storm main or street. Landscaping and walks shall be installed so that the surface drainage system is not disrupted. The applicant shall prepare detailed lot drainage requirements and shall include them in the CC&R's for each lot. Specific reference to these requirements shall be made in the deed for each lot. c. The applicant shall implement the recommendations and plans addressing expansive soils. The soils engineer, Resolution No. PC-91-19 March 13, 1991
