20220721 16514900 1.0 TRUE Sediment Impaired Habitats This feature class depicts coastal areas where habitat function has been impaired by a sediment-related issue. This often involves the loss of the majority of sediment exchange between a coastal marsh and the open coast due to the presence of infrastructure such as a highway. Locations of habitats digitized by James Zoulas (CESPN-ET-EI) using NAIP 2010 imagery at a scale of 1:1,000. Digitized areas were validated using California Coastal Records Project (http://www.californiacoastline.org/) oblique aerial photos and Google Earth imagery.
