Upper Santa Ana Wash Land Management and Habitat Conservation Plan (Wash Plan)

Article Index


In 1993, representatives of numerous agencies - including water, mining, flood control, wildlife, and municipal interests - formed a Wash Committee to address mining issues that were local to the upper Santa Ana River wash area. The role of the Committee was subsequently expanded and it began meeting in 1997 to determine how this area might accommodate all of the important functions represented by the participating agencies.

The Wash Committee seeks to disregard land ownership lines in favor of a "best use" strategy for land use planning. It is anticipated, for example, that significantly disturbed areas are more favorable for mining while undisturbed lands are more favorable for preservation. This project produced a Land Management and Habitat Conservation Plan for the wash planning area, covering 4,500 acres ranging from the mouth of the Santa Ana River canyon to Alabama Street in the Santa Ana River wash.

A primary purpose of the exchange is for the Bureau of Land Management to dispose of isolated lands which have been previously degraded by mining activities within the Santa Ana River Wash ACEC, and in exchange, to acquire District lands with high habitat value adjacent to existing ACEC parcels. The exchange will allow the BLM to consolidate fragmented parcels with high-quality habitat, resulting in improved management of the ACEC. View the Draft EIS and Ammended Plan.

Wash Plan Final Environmental Impact Report (EIR)

The purpose of the proposed project is to allow the continued use of land and mineral resources while maintaining the biological and hydrological resources of the Planning Area in an environmentally sensitive manner. The Wash Plan is intended to coordinate and manage the present and future activities in the Wash, which are under multiple jurisdictions, each with different needs. The goal of the proposed project is to balance the ground-disturbing activities of aggregate mining, water conservation, and other public services, including recreational activities with quality, natural habitat for endangered, threatened, and sensitive species.
