The ground-water basin beneath the city of Thousand Oaks, Calif., corresponds closely in area with the surface-water drainage basin of Conejo Valley. Before World War II there was little ground-water development. After World War II, urban development put a stress on the ground-water basin; many wells were drilled and water levels in wells were drawn down as much as 300 feet in places. Beginning in 1963, imported water replaced domestic and municipal ground-water systems, and water levels rapidly recovered to predevelopment levels or nearly so. Most of the ground water in the Thousand Oaks area is stored in fractured basalt of the middle Miocene Conejo Volcanics. Depending on the degree of occurrence of open fractures and cavities in the basalt, recoverable ground water in the upper 300 to 500 feet of aquifer is estimated to be between 400,000 and 600,000 acre-feet. The yield of water from wells in the area ranges from 17 to 1,080 gallons per minute. Most of the ground-water in the eastern part of the valley is high insulfate and has a dissolved-solids concentration greater than 1,000 milligrams per liter. In the western part of the valley the ground-water is mostly of a bicarbonate type, and the dissolved-solids concentration is less than 800 milligrams per liter. In most areas of Conejo Valley, ground-water is a viable resource for irrigation of public lands and recreation areas. (USGS)

This book introduces community planning as practiced in the United States, focusing on the comprehensive plan. Sometimes known by other names—especially master plan or general plan—the type of plan described here is the predominant form of general governmental planning in the U.S. Although many government agencies make plans for their own programs or facilities, the comprehensive plan is the only planning document that considers multiple programs and that accounts for activities on all land located within the planning area, including both public and private property. Written by a former president of the American Planning Association, Community Planning is thorough, specific, and timely. It addresses such important contemporary issues as sustainability, walkable communities, the role of urban design in public safety, changes in housing needs for a changing population, and multi-modal transportation planning. Unlike competing books, it addresses all of these topics in the context of the local comprehensive plan. There is a broad audience for this book: planning students, practicing planners, and individual citizens who want to better understand local planning and land use controls. Boxes at the end of each chapter explain how professional planners and individual citizens, respectively, typically engage the issues addressed in the chapter. For all readers, Community Planning provides a pragmatic view of the comprehensive plan, clearly explained by a respected authority.
