Measure A

Measure A protects the parks, open spaces, and agricultural lands that make Marin an extraordinary place to live, work, and play.

Measure A's quarter-cent sales tax supports parks, open space, and sustainable agriculture across Marin. Measure A funds can't be used for any other purpose.

In June 2022, voters approved re-implementation of Parks Measure A. This followed the approval of the one-quarter of one percent sales tax (County Ordinance 3586) that passed in 2012 to support parks, open space, and agricultural lands across Marin. In accordance with this law, for the next ten years, funds raised by Parks Measure A will continue to be spent on parks and open space, sustainable agriculture, recreation in Marin's nineteen cities and towns, and land acquisition. 

Since 2013, Measure A funds have supported infrastructure repairs, vegetation management, conservation, and public programs. Measure A has funded collaboration with Marin County Fire and regional fire agencies to maintain defensible space, community outreach on the road and trail designation process, an Inclusive Access plan, community grants, and other initiatives that keep parks and open spaces enjoyable, safe, and sustainable for all.
