<br />plans must include measures for reducing the likelihood of <br />earthquake caused landslides. In addition, the liquefaction <br />potential of the soil must be evaluated. If a high liquefaction <br />potential exists then recommendations for minimizing future <br />damage must be incorporated into the subdivision design. <br /> <br />77. (MM 9.F.2) All buildings should be designed and constructed in <br />accordance with the City of Pleasanton building codes, <br />particularly those sections of the codes regarding earthquake <br />resistant design. The geotechnical investigation report for <br />each lot should include earthquake design recommendations <br />including recommendations for site period or soil profile <br />coefficient as well as a discussion of seismically induced <br />landslides. <br /> <br />78. (MM 9.G.1) The surface drainage system for the development as <br />a whole should be evaluated by the geotechnical engineer and <br />engineering geologist in order to determine the effects of the <br />surface drainage system on springs and the groundwater regime at <br />the site. <br /> <br />79. (MM 9.G.2) The recommendations of the geotechnical engineer and <br />engineering geologist should be implemented by the developer's <br />contractor during subdivision grading. All cut and fill slopes <br />should be inspected by the engineering geologist during grading <br />in order to locate and evaluate any new springs which may be <br />found during grading operations. The location of all subsurface <br />drains should be shown on as-built drawings. <br /> <br />80. (MM 9.G.3) The individual homeowners should avoid over- <br />irrigating landscaped areas. Excessive irrigation water is a <br />common cause of groundwater seepage problems. In addition, the <br />recommendations of the geotechnical engineer and engineering <br />geologist should be implemented by the lot owner's contractor <br />during lot grading. All cut and fill slopes should be inspected <br />by the engineering geologist during grading in order to locate <br />and evaluate any new springs which may be found during grading <br />operations. The location of all subsurface drains should be <br />shown on as-built drawings. <br /> <br />Modifications to the Architectural Guidelines (OTFAG) <br /> <br />81. The standards for the Zone 1 lots listed in the Oak Tree Farm <br />Architectural Guidelines (OTFAG) shall be modified as follows: <br />(MM 5u) <br /> <br />a. The side setback requirements of the WFRCOD shall apply to <br />these lots. <br /> <br />b. The maximum floor area permitted for these homes is 4,500 <br />square feet, regardless of lot size. <br />
