KLEINFELDER <br /> An employee.w.x c.mp,py <br /> File No. 23197.G01 <br /> February 14, 2003 <br /> Mr. Ryan Voorhees <br /> CRV Enterprises, Inc. <br /> 28082 Nichols Road <br /> Galt, CA 95637 <br /> Subject: SOILS SUITABILITY AND NITRATE LOADING STUDY <br /> PROPOSED 8-ACRE SUBDIVISION <br /> PETERS, CALIFORNIA <br /> Dear Mr. Vorhees: <br /> Kleinfelder is pleased to present the results of our soil suitability and nitrate loading study for the <br /> proposed 8-acre subdivision to be located in Peters, California. The purpose of our study was to <br /> determine the suitability of the property for septic tank usage. The study was performed in <br /> general accordance to the requirements of Section 9-10100© of San Joaquin County Ordinance. <br /> The following includes background information regarding the proposed development, present <br /> and past use of the site, and the historical groundwater information in the project area. In <br /> addition, discussions regarding our investigative procedures and the site conditions encountered <br /> during our field exploration, and the results of percolation tests are presented. Finally, the results <br /> of our nitrate loading calculations and project limitations are provided. <br /> PROPOSED DEVELOPMENT <br /> On a preliminary basis, we understand the subject 8-acre project site will be subdivided into four <br /> individual 2-acre lots for single-family residences. Appurtenant construction will include a <br /> paved interior street, various concrete flatwork, and buried utilities. We anticipate the proposed <br /> residences will be one and/or two story, wood frame structures with shallow spread foundations <br /> and concrete slab-on-grade floor systems. Grading plans were not available at the time this <br /> report was prepared. However, as site topography is gently sloping, cuts and fills during <br /> earthwork may be on the order of 5 to 10 feet to provide level building pads. <br /> We anticipate that waste disposal for each residence will be provided by an individual on-site <br /> sewage disposal system consisting of a conventional 1,200 to 1,500 gallon septic tank/leach <br /> trench disposal system and may include seepage pits. We anticipate that disposal trenches may <br /> be cut deep in order to intersect suitable percolating soils or shallow leach lines will lead to <br /> seepage pits or wells for disposal of effluent. <br /> 23197.G01/ST03R290 February 14,2003 <br /> ©2003 Kleinfelder,Inc.
