Do you live in Mill Valley, Tiburon, Sausalito, Marin City, Tamalpais Valley, or Belvedere?  These communities are linked together by the watershed lands draining to Richardson Bay, a shallow, protected, biologically-rich wildlife preserve.  Mount Tamalpais, the highest point in Marin County, rises steeply above the Bay and its surrounding ridges are protected as public open space and support a myriad of plant and wildlife communities.

Zone Information

Zone 4 was created in 1957 to alleviate chronic flooding in Bel Aire and adjacent undeveloped lands.  The boundaries of the zone were later amended to include Strawberry Circle.  It is overseen by a 5-member Advisory Board.

Zone 4 is small, covering only 0.85 square miles and includes parts of the Town of Tiburon and unincorporated Bel Aire and Strawberry Circle. There are 850 parcels in the Zone.

The boundaries of the Zone include the subwatersheds of East and west Creeks and Salt Works Canal, all of which drain to Richardson Bay.

The Zone 4 work program includes regular servicing of 8 pumps at 3 pump stations, maintenance of 0.15 miles of flood protection levees, maintenance of tidegates and trash racks, and an annual vegetation maintenance program along 0.9 mile of creek.

Zone 3 was formed in 1956 to address creek and tidal flooding adjacent to Richardson Bay and is overseen by a 7-member Advisory Board.

Zone 3 covers over 13 square miles, including the City of Mill Valley and numerous unincorporated communities including Marin City, Alto, Sutton Manor, Almonte, Tamalpais Valley, Homestead Valley, and portions of Strawberry Point.  There are 12,560 parcels in the Zone.

The boundaries of the Zone include the subwatersheds of Arroyo Corte Madera del Presidio, Warner Creek, and Coyote Creek, all of which drain to Richardson Bay.

The Zone 3 work program includes regular servicing of 13 pumps at 5 pump stations, maintenance of 1.3 miles of flood protection levees, maintenance of tidegates and trash racks, and an annual vegetation maintenance program along 3 miles of creek. In addition, Zone 3 periodically dredges lower Coyote Creek to remove accumulated sediment in the concrete chancel to improve flow conveyance.
