POD! Change in Percent Urban Land by Hydrodynamic Subregion, Upper San Francisco Estuary, California 1990-2006

Land use is an ultimate driver of many of the stressors on the Upper San Francisco Estuary, but the magnitude and pattern of land use change had not previously been analyzed. I attempted to fill this knowledge gap through a screening-level risk assessment. I compared urban land use within hydrodynamic subregions in 1990, 2000, and 2006. A GIS analysis was performed to calculate the percent of land area within each subregion that was classified as urban and built-up land by the California Farmland Mapping and Monitoring Program (http://www.consrv.ca.gov/dlrp/fmmp/) for those dates.
