Land Preservation and Park Access Grants

The purpose of the Lands Preservation and Park Access Grant Program is to assist Cities, Towns and other qualifying organizations in the acquisition of open space and park properties that improve access to parks and preserve natural resources.

• To support the acquisition of land for the permanent protection of streams, bay lands, native ecosystems, habitat for special status species, and other natural or scenic areas with high resource values, or to improve access to parks and recreation facilities within Marin County.
• To support access to park and recreation experiences and the preservation of natural areas by qualified organizations.
• To the extent possible, leverage matching funds from public and private partners.

Parks Measure A is the primary source of the funding for Land Preservation Grants. Measure A (Marin County Ordinance 3760) allocates 10% of Parks and Open Space annual Measure A tax revenue for preservation of natural lands and improving access to park and recreation facilities.

The County intends these grants to be used as "seed money"; to assist qualified organizations in their fund-raising efforts. To the maximum extent possible, the Qualifying Organizations shall use Measure A funds to leverage money from other sources, including private and public donations and grants.

Generally, a Land Preservation Grant will fund approximately 50% of the land acquisition price or $100,000, whichever is lower, with the remaining funding coming from other sources. The County of Marin may make exceptions for high priority acquisitions.

These grants are subject to the availability of Measure A funds. The Measure A sales tax expires in October 2031; Measure A Program funds may be available for a limited amount of time afterward until funds are exhausted.

For purposes of the Lands Preservation and Park Access Grant Program, a Qualified Organization includes:

• Incorporated City or Town within Marin County
• A special district, or similar organization, within Marin County established under state law for the purposes of protecting of natural, cultural, historic, and scenic resources
• An organization qualified under Internal Revenue Code Sections 501(c)(3) and 170(h) whose primary purpose is the preservation and protection of open space, natural resources, historic and cultural values, recreational use, and scenic areas
• For the acquisition of conservation easements, the qualified organization must demonstrate the ability to monitor and enforce the easement in accordance with Land Trust Alliance Standards and Practices
• An organization qualified under Internal Revenue Code Sections 501(c)(3) and 170(h) whose primary purpose is to be a community-based organization representing communities of color and/or low-income communities, Indigenous communities and Tribal governments.

• Marin Countywide Plan
• Marin County Local Coastal Program
