The Plan area includes approximately 12 miles of the Santa Maria/Sisquoc Rivers from the Santa Maria City boundary at the downstream project limit to just east of the La Brea Creek confluence at the upstream project limit. The Plan also includes areas adjacent to the river channel planned for off-channel mining operations and a buffer area separating mining operations from other land uses. Mining operations within the Plan area are conducted by Coast Rock Products, Inc. and Kaiser Sand and Gravel, Inc. and are proposed to be carried out in phases over a period of 23 (Kaiser) to approximately 64 (Coast Rock) years. Mining and reclamation activities within the Plan area are under the direct jurisdiction of Santa Barbara County (2493.5 acres), San Luis Obispo County (654.7) and the U.S. Army Corps of Engineers (only within “Waters of the United States”), in consultation with various other government agencies. The overall goal of the Plan is to provide for the long term production and conservation of the sand and gravel mineral resource in the Sisquoc and Santa Maria Rivers, in a manner compatible with existing surrounding land use, while minimizing adverse'impacts to the environment. This Plan is also intended to coordinate the mining and reclamation activities of the two major mining operators in the project area and provide a long-term planning framework for all the public agencies involved in project review. This Plan sets forth goals, objectives, and policies for resource utilization and protection, and environmental protection, as well as operation, reclamation, and monitoring criteria. All actions taken by the regulatory agencies involving plan review and approval for mining and reclamation within the Plan area must be consistent with this Plan. i A m — ■ X- •• ESC -v- V* • • ■*: V The Sisquoc River Upstream from Tepusquet Crossing V__ Bndmy N KINGS ( COUNTY SAMAXTOKO V MONIREY COUNTY K ras SAN UfiS OBISPO COUNTY MACOtSDtTO i ChoUmo Sm Simoon stag Pooo Cambria Ataacadaro KERN COUNTY its whale toa "rag s.
