Marin County wants to hear from the public as it updates its countywide septic regulations, known as the Local Agency Management Plan (LAMP). This update matters for households across west Marin and parts of east Marin that use individual septic systems instead of centralized sewer services.
The county’s aiming to protect public health and water quality, but also wants to support local agriculture and housing where there’s no sewer access. If Marin goes with its own LAMP, officials say it could allow for alternative septic systems and more flexible wastewater calculations. That might make it easier for folks to improve their homes in places like Fairfax, San Anselmo, and Mill Valley.

The State Water Board still has the final say, but Marin hopes to shape rules that fit local conditions. The process covers communities from Bolinas and Point Reyes Station to Novato and San Rafael.
Understanding Marin County’s Local Agency Management Plan Update
The Local Agency Management Plan, or LAMP, sets the rules for how Marin permits, inspects, and maintains septic systems. This isn’t just paperwork—it affects daily life in places like San Geronimo Valley, Olema, and Inverness, where septic tanks are essential for homes and farms.
Marin wants a plan that reflects the real needs of coastal towns like Sausalito and Tiburon, plus inland communities. The main idea? Align septic oversight with local watershed goals and economic realities, while keeping water safe for Tomales Bay and the coast. County staff say they’ll take resident input seriously as the LAMP evolves.
What the update could mean for Marin residents
The LAMP update could bring real changes for households and small farms. People might get to use alternative septic systems and see more flexible wastewater calculations. In places like Fairfax, Larkspur, Corte Madera, and San Anselmo, this could mean an easier time making routine improvements or adding modest housing.
The plan also tries to protect water quality near Bolinas and Point Reyes Station, while helping agriculture in rural west Marin. The State Water Board still has to approve any new rules, but Marin’s proposal would reflect local needs and feedback.
- Marin-specific approach: Custom septic rules designed for the county’s coastal and rural areas, from Mill Valley to the Lagunitas Creek watershed.
- Alternative systems: Possible new treatment technologies for dense neighborhoods in San Rafael and hillside parcels around San Geronimo Valley.
- Flexible wastewater calculations: Adjusted methods that consider Marin’s unique soil, groundwater, and weather.
- Housing and improvements: Fewer obstacles for home renovations and small development where there’s no sewer access.
- State Water Board alignment: Local rules still need state approval to ensure public health and water quality standards.
Public input opportunities and timeline
County staff are hosting a series of public meetings and drop-in sessions through spring 2026. They want to hear from residents in towns like Novato, San Rafael, San Anselmo, Belvedere, and Greenbrae.
There’s a countywide webinar on April 2. In-person sessions are coming to Novato, Bolinas, and the San Geronimo Valley, with drop-in gatherings in Point Reyes Station. Marin wants input from both coastal spots like Tomales and Stinson Beach and inland places like Fairfax and San Geronimo. They’ll use this feedback to shape the regulation update, though the final decisions are still up to the county and state.
How to participate and what to expect
Residents, groups, and organizations can reach out to County experts by phone or email to request meetings. They can also sign up for updates if they want to stay in the loop.
Disability accommodations and alternative document formats are available if you ask, making sure everyone in Marin—whether you’re in Tiburon, Sausalito, Corte Madera, or Ross—can participate. County staff will listen, jot down your feedback, and include your input as the LAMP develops, but the final decisions lie with state authorities after the county wraps up its public process.
- Join the April 2 countywide webinar from any Marin city—Novato, San Rafael, Mill Valley, Larkspur, wherever you happen to be.
