In 2013, the California Regional Water Quality Control Board ordered Ross Valley Sanitary District to fix aging sewer infrastructure. Aging infrastructure causes rainwater infiltration, which can lead to sewer overflows or discharge of partially untreated wastewater into the San Francisco Bay. 

The order compelled the District to phase in a Private Sewer Lateral Ordinance. All requirements went into effect July 1, 2014, except those relating to property sales, which became effective January 1, 2015.

Private Sewer Lateral Ordinance

Property owners must obtain a Certificate of Compliance from the District for any of the following conditions: buying or selling a property, remodeling in excess of $75,000, or adding a bathroom.

  1. Jurisdiction
  2. Property Sales & Remodels
  3. Steps for Compliance
  4. CIDs/HOAs

The District’s jurisdiction includes the City of Larkspur, Town of Ross, Town of San Anselmo, Town of Fairfax, and the unincorporated areas within the boundaries including Sleepy Hollow, Kentfield, Greenbrae, Fairfax, and San Anselmo.
