Abstract:

The purpose of the map series presented here is to visually present the identified aquatic resources in San Jacinto River and portions of the Santa Margarita River watersheds in western Riverside County, California, as part of the Special Area Management Plan SAMP. A SAMP is a comprehensive aquatic resource planning effort in the context of Section 404 of the Clean Water Act CWA. The U.S. Army Corps of Engineers, Los Angeles District is leading the development of the SAMP, and the Riverside County Flood Control District, representing the County of Riverside, is the local stakeholder. These are the spatial results of an overall study undertaken by the SAMP. The size of the study area is 36,1953 ha 894,405 acres. Mapped results of this study were compiled in the field using ArcView 3.2 geographic information system GIS and mapped at a scale of 14800 using Color Infra-Red Digital Orthoquads DOQ imagery. A unique method of combining the occurrence of vegetation communities and fluvial surfaces to determine the probability of being regulated was used to identify aquatic resources that might be considered as regulated under Section 404 of the CWA.
