Beginning in 1991, a major effort was initiated to develop a management plan for the Santa Clara River and its many resources. In excess of $1 million in funding and in-kind services has been spent to date developing the Plan. Funding for the Plan has been provided by the State of California Coastal Conservancy (Coastal Conservancy), the State Wildlife Conservation Board, the U. S. Fish and Wildlife Service, the cities of Santa Clarita and San Buenaventura, and Ventura and Los Angeles County Flood Control Districts. Plan preparation is directed by a 26-member Project Steering Committee consisting of representatives of the counties, communities, state and federal agencies, property owners, aggregate producers, water agencies and Friends of the Santa Clara River. The Steering Committee began by identifying the river's critical issue areas. Reports were developed by subcommittees covering biology, water resources, flood control, agriculture, aggregate mining, and recreation that provide background information, goals and recommendations for the river on the various issue areas. A series of computer-based maps covering the entire river were produced, and have been used in a Geographic Information Systems overlay process to identify conflicts and opportunities, and to facilitate decisions regarding uses of the river floodplain. The Steering Committee, in early 1999, approved a set of riverwide and reach-by-reach recommendations which are to be incorporated into the Plan. AMEC Earth and Environmental, the Plan consultant, completed a draft Plan in January 2004. The Plan can be viewed at sdgis.amec.com/scremp/.
