May AA, 2007 �a0 UHOLmuaC AMD >ST� cC®V�E�ISfBC�DVZ9 A geologic map of the area was reviewed and indicated the surface soils are described as Holocene Age natural levee and channel deposits. The site is located in Seismic Zone 3' and all structures should be designed accordingly. The closest active Class B fault is the Greenville fault zone along parts of the western San Joaquin Valley located a distance of 54 kilometers. The UBC currently considers non -blind thrust faults for seismic design parameters. The closest Class A fault is the Rodgers Creels fault located at a distance of 81 kilometerS2. The California Geological Survey assigns a probabilistic (10% probability of exceeding that motion in a 50 year period) peak horizontal ground acceleration for surface soil at the subject site of 0.236g based on longitude and latitude coordinate53. A liquefaction evaluation was performed for this site and is discussed In a subsequent section of this report. Following is a table of the 2001 California Building Code Soil Parameters2 which may be used for design of structures at the subject site: The general topography of the site and surrounding area is relatively flat. The site consisted of an open agricultural field. The area of the pump station is an unused portion of the field, on the north side of the pump station site there is an existing telecommunications monopole tower with an equipment building. The site Is bordered by agricultural fields and orchards on the north, west, and south sides, and by North Cameron Road on the east.
