MOUNTAIN HOUSE NEIGHBORHOOD' 'PROJECT INITIAL STUDY Condition of Approval GEO-2:. The following recommendations of the project's Geotechnical Report shall be implemented. • On-site and off-site soil that is used for engineered fill shall meet the specifications of the Geotechnical Report. • A sample of proposed import soil for engineered fill shall be tested prior to use to determine if it is suitable as engineeredfill • Any open cuts shall be in compliance with applicable OSHA regulations(California Construction Safety Orders, Title 8) and shall be closely monitored for evidence of incipient instability. • Dewatering may be necessary,given the depth to groundwater at the site Any dewatering design shall be submitted for review by the geotechnical engineer prior to construction. • At the time of grading, depth to groundwater shall be determined, and at a minimum, the groundwater shall be lowered and maintained at least 2 feet below the bottom of the excavation. • Prior to issuance of building permits, more site-specific investigations involving more detailed geotechnical exploration shall be completed At this phase, the Geotechnical Report included only 24 test borings over 365 acres and was intended for use in preliminary planning and design of all of Neighborhood 'W • Piping and utility connections shall be designed to accommodate the estimated maximum foundation settlements • Foundation soils shall be tested immediately prior to placement of concrete to verify that the soils water content is acceptable • Prior to issuance of building permits, a detailed grading and drainage plan shall be prepared for all areas subject to development. • Additional exploration shall be performed once specific site development plans are available • A qualified inspector shall be present at the site to observe and advise during site preparation, earthwork,grading, and construction of foundations,slabs on grade and earth-retaining structures. • If more than two years elapse between the date of the Geotechnical Report(January 1999) and beginning of construction, the Geotechnical Report shall be updated. e) Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water? No septic tanks or alternative waste water disposal systems are proposed at the project site. All wastewater would be collected in a piping system connected to the proposed wastewater treatment plant north of the site. Data Sources for Geological Analysis Condor Earth Technologies, Inc. 2000.
