The County of Marin Department of Public Works manages County Service Area (CSA) #6 for the Gallinas Creek community. This CSA is governed by the Marin County Board of Supervisors which appoints a five-member board to the CSA #6 Advisory Board. The Advisory Board advises the Board of Supervisors on all matters relating to projects, programs, and budgets of CSA #6.
The CSA #6 boundary includes properties along the south fork of the Gallinas Creek extending downstream to Bucks Landing off North San Pedro Road, including the Marin Lagoon neighborhood properties. A portion of the basic property tax (ad valorem tax) is secured for CSA #6 from the properties in the CSA #6 boundary to raise funds for periodic dredging of the main creek channel for recreational boating purposes, including a smaller channel around Santa Margarita Island. Prior dredging episodes occurred in 1966, 1973, 1981, and 1992-1994.
