No, CMSD is a separate public agency. We are an independent special district that was formed in 1944 under the Sanitary District Act of 1923.

Independent special districts are a form of local government that are created by a community to provide a limited number of designated functions, such as water, parks, fire protection and solid waste and wastewater collection. They operate under a locally elected Board of Directors that oversee district functions.

Prior to the incorporation of the City of Costa Mesa in 1953, local community members disposed of their trash in a landfill that was owned and operated by the City of Newport Beach. As the landfill began to near capacity, permission to use the site was limited to Newport Beach residents only. Out of concern for their community’s health and safety, residents of what is now Costa Mesa filed a petition with the Orange County Board of Supervisors on June 22, 1943 to establish CMSD under the provisions of California’s Health and Safety Code. On December 21, 1943, the Board of Supervisors approved of CMSD’s boundaries and ordered special elections to be held on February 8, 1944 to officially form CMSD and elect its first five-member Board of Directors.

CMSD provides solid waste (trash) and wastewater (sewer) collection services to the city of Costa Mesa, as well as small portions of the city of Newport Beach and unincorporated Orange County. To view our service area, visit our Service Area Map.
