Description:
Abstract:
This dataset distinguishes coastal wetlands from inland wetlands while retaining the attributes from the original National Wetlands Invertory (NWI) data.
Purpose:
To determine the current spatial extent of coastal wetlands along the California coast and in the San Francisco Bay.
Supplemental_Information:
This data is derived from the National Wetlands Inventory available online at: www.nwi.fws.gov, and data developed at the Pacific Institute.

Process_Description:
All polygons within a buffer of 100 feet of the estimated mean higher high water line were selected using the select by location function.

Process_Description:
UPDATE April 28, 2009. The dataset was manually edited to remove wetland features that should not be classified as "coastal wetlands". These included several "lakes" off the coast of Southern California. These polygons were included in the original National Wetlands Inventory Dataset, and appear to be areas with kelp forests. Also, many riverine segments (mostly in Humboldt, Mendocino, Monterey, and San Luis Obispo counties) were removed or truncated, as they often extended up to several hundred feet in elevation inland, and obviously do not qualify as coastal wetlands. We also removed lakes above an elevation of 100 feet south of Pismo in San Luis Obispo County, and gravel pits in the Santa Clara River valley in Ventura County.
