Coastal Zone Management Act Boundary

This data depicts the California Coastal Commission's Coastal Zone Boundary. It was digitized within AutoCAD from the Commission's certified Coastal Zone Boundary hard copy maps. The files were then imported into ArcView, and merged together following Commission jurisdictional boundaries (North Coast, North Central Coast, Central Coast, South Central Coast, South Coast, and San Diego). The line work was originally georeferenced to the 1:24,000 scale USGS Digital Raster Graphics (DRG) in Teale Albers projection. The data was later refined to the 1:24,000 scale USGS DRGs in UTM, Zones 10 and 11, NAD 83 meters. This file is intended to be displayed no larger than 1:24,000 scale upon the USGS UTM DRGs base map. In addition, the data was later attributed to help explain the basis of the mapped Coastal Zone. Please note- the digital version of the CZB created by developing this shapefile is a conformed copy of the official boundary adopted by the Commission in 1977. This data does not reflect all minor adjustments to the Coastal Zone Boundary that have been subsequently certified by the Commission. Such adjustments are reflected in the cadastral (parcel-based) County depictions of the adopted Coastal Zone Boundary.
