Document Description
The Park District proposes to adopt a Land Use Plan Amendment (LUPA) for the southern region of Las Trampas Wilderness Regional Preserve (Las Trampas) in south-central Contra Costa County to formally incorporate approximately 756 acres of parkland into the regional preserve. This addition will expand the amount of parkland in Las Trampas to a total of approximately 6,000 acres. The LUPA provides a formal planning review for the expansion of Las Trampas, outlines public access connections, and catalogs and plans for important natural and cultural resources for five parcels in the project area. The five parcels include four that the Park District currently owns: Chen, Elworthy, Peter's Ranch, and Podva. The LUPA describes and outlines recommendations for each parcel. On the Chen parcel, the LUPA recommends a staging area and Emergency Vehicle and Maintenance Access (EVMA) road and recreational trail connection. The LUPA also evaluates public access to Las Trampas and along the Calaveras Ridge Trail via Peter's Ranch, as well as trail connections to the Podva parcel. Furthermore, the LUPA serves as a resource for park operations and maintenance, summarizi ng long-term management plans for conservation easements, detailing the grazing plan for all parcels, and outlining roles and responsibilities for park staff on all five subject parcels.
