The predominantfeature of this region is San Francisco Bayand the miles of shoreline, both on thePacific coast and along the bay, extendingnorth to Sonoma County, inland to the Delta, and south to San Jose. Theurbanized areas are concentrated primarily around the bay. To the north andsouth, the region is characterized by low coastal mountains (CDFG, 2007).Sonoma and Napa counties produce wine grapes valued over $850 million in2010 (California Farm Bureau Federation, 2012). To the east, Solano and ContraCosta counties are on the western edge of the low-lying California Delta.Communities in the Bay Area should consider evaluating the following climatechange impacts:• Increased temperatures• Reduced precipitation• Sea level rise – coastal inundation and erosion• Public health – heat and air pollution• Reduced agricultural productivity (e.g., wine grapes)• Inland flooding• Reduced tourismAPG: UNDERSTANDING REGIONAL CHARACTERISTICS PAGE 28
