05 November 2014 AGE Project No. 14-3119 Page 5 of 17 The church building is to have two bathrooms (sink and toilet) to accommodate the employees and potential visitors. A kitchen with appliances has been proposed. Waste products related to the use of the facility for cooking and limited dishwashing is proposed and will be disposed of through the septic system. Visitors will be 99 when the church is completed and an estimated 25 hours per week operating schedule. The estimated rate of visitors per day is 50 to 99 people. The reasonable or maximum usage of the two bathroom facility by any customer is 100 percent. The average and reasonable usage of three to five gallons per day per person typical for a visitor to a church setting. Staff for the proposed church will consist of up to five people working a 25 hour work week (three days a week). The average and reasonable usage of 5 gallons per day per person typical for a worker at a commercial location/church setting. 4.0. GROUNDWATER INFORMATION - REGIONAL HYDROGEOLOGY The Geologic Map of California, published in 1966 by the California Department of Conservation Division of Mines and Geology, shows the site area within the Great Valley Syncline (GVS), a large, elongate, northwest trending structural trough. The GVS is subdivided into two major divisions designated the Sacramento and San Joaquin Valleys, which have been filled to the present elevation with thick sequences of sediment ranging in age from Jurassic to present day, creating a nearly flat-lying alluvial plain extending from the Tehachapi Mountains in the south to the Klamath Mountains in the north. The western and eastern boundaries of this province are comprised of the California Coast Range and the Sierra Nevada, respectively. Geologically, the area around the subject property generally consists of Holocene-aged flood-basin deposits of clay, silt, and sand. Miocene to Holocene age-units are located in the surrounding area. These deposits are heterogeneous mix of generally poorly sorted clay, silt, sand, and gravel with some beds of claystone, siltstone, sandstone, and conglomerate (Page, 1986). Most of the fresh ground water in the Central Valley is contained in the post- Eocene-aged continental rocks and deposits and in the Holocene-aged river deposits consisting of gravel, sand, silt, and minor amounts of clay. In general, these geologic materials comprise a major widespread aquifer extending hundreds of feet deep and occasionally containing individual confining layers. The Modesto, Riverbank, Turlock Lake Formations and overlying recent alluvium are the principal source of domestic ground water in the 13,500-square mile San Joaquin Valley Ground Water Basin (Basin 5-22). This basin is drained primarily by the San Joaquin River, which is approximately 15 miles north of the subject property. The nearest surface water feature in the vicinity of the property is the Old River, located approximately 2,750 feet northeast of the property. Admnced GcoE.iironmentsl,Inc.
