The Resource Conservation District of Greater San Diego County in Lakeside is an independent special district organized in 1995 under Division 9 of the California Public Resources Code, headquartered at 11769 Waterhill Rd. The district shares its Waterhill Rd offices with the Fire Safe Council of San Diego County, coordinating wildfire fuel-reduction education and post-fire erosion-control assessments across the same East County terrain. As a non-regulatory entity, the RCD administers watershed restoration, pollinator habitat revitalization, carbon farming research, and conservation scholarship programs spanning a 2,886-square-mile service area from the Bonsall community to the U.S.-Mexico border. Agricultural outreach extends to sustainable soil-health consulting for ranchers and growers along rural corridors east of Lakeside, including the vineyard operations at Trevi Hills Winery on Muth Valley Rd. Current program priorities include USDA-partnered technical assistance for post-wildfire slope stabilization, native-seed revegetation planning, and stormwater-quality monitoring across ten distinct San Diego County watersheds.
