Private Lateral Model Ordinance

The Sewerage Agency of Southern Marin (SASM) Board of Commissioners approved a Private Lateral Model Ordinance in June 2014, and encouraged its member agencies to adopt it. The six member agencies include the City of Mill Valley, Alto Sanitary District, Almonte Sanitary District, Homestead Valley Sanitary District, Richardson Bay Sanitary District and the Kay Park area of Tamalpais Community Services District. If you own a property in any of these areas, a sewer lateral ordinance applies to you.
