Clayton Regency is a mobile home park in rural eastern Contra Costa County. The County developed a plan to provide the park with a permanent supply of potable water through a water line extension. However, the extension was controversial as no other landowners along the 3-mile line would be served. This was one of the first projects to go through the East Contra Costa County Habitat Conservation Plan planning and permitting process. We helped the client and the County resolve conflicts between the HCP and CEQA and fulfill the County’s objectives.
