Description: Created from a combination of the coastal zone and the co_bndry.shp county boundary. The coastal zone was used for the majority of the polygon and the county boundary was used for creating morro bay. For Monterey and Santa Barbara Counties the source was the Air Resources Board arb_california_counties_aligned_03.shp file. This file was downloaded from http://gis.ca.gov/casil/boundaries Credit: Maintained by various County of San Luis Obispo GIS Staff.
