The Marin Wildfire Prevention Authority Measure C is a special tax charged to all parcels of real property located in Marin County within the defined boundary of the “Member Taxing Entities.” The voters approved this parcel tax in March 2020, by approximately 71%, for a period of ten years starting with the 2020/21 fiscal year.

The “Member Taxing Entities” consists of the following local agencies:

  • Cities of San Rafael, Mill Valley and Larkspur
  • Towns of San Anselmo, Corte Madera, Fairfax, and Ross
  • County of Marin (including Service Areas 13, 19 and 31)
  • Fire Protection Districts of Southern Marin, Novato, Kentfield, Stinson Beach, Bolinas, and Sleepy Hollow
  • Marinwood Community Services District
  • Inverness Public Utility District
  • Muir Beach Community Services District

A general map of the boundaries is shown below.

The revenues raised by this tax are used solely to plan, finance, implement, manage, own, and operate a multi-jurisdictional agency to prevent and mitigate wildfires in Marin County. It is the purpose and intent of this ordinance to impose a special parcel tax for fire protection and prevention services, including but not limited to:

  • Vegetation management
  • Wildfire detection
  • Evacuation plans and alerts
  • Grants
  • Public education
  • Defensible space and fire-resistant structure evaluations
  • Local-specific wildfire prevention efforts

Such funds are to be spent and administered in each of the five Marin Wildfire Prevention Authority Operational Zones, as set forth in the Joint Powers Authority (JPA) Operational Boundaries Map (shown below).

Parcel Tax Details:

The parcel tax will raise approximately $19 million annually to plan, finance, implement, manage, own, and operate a multi-jurisdictional agency to prevent and mitigate wildfires in Marin County. Beginning in the 2020/21 fiscal year and continuing for 10 years, the special tax will expire at the end of the 2029/30 fiscal year.

The maximum tax per year for each property type will be adjusted to reflect any increase in the Consumer Price Index (“CPI”) beyond the first fiscal year. The increase shall be the lesser of three percent (3%) or CPI as calculated from February of the immediately preceding year to February of the current year.

The Marin County Tax Collector records shall provide the basis for determining the annual calculation of the special parcel tax applicable to each parcel, with such corrections as deemed necessary by the Board of Directors for the Marin Wildfire Prevention Authority to reflect the actual use and improvement of any parcel.

The rates below are for tax year 2023/24.

Special Tax Lien:

Per state law, a Notice of Special Tax Lien is required to be recorded on properties subject to Measure C. The Measure C Special Tax Lien is recorded on property documents as “MWPA.” The Notice of Special Tax Lien is NOT a traditional financial lien and DOES NOT mean that property taxes are delinquent or have not been paid.

Can I discharge the special tax lien?

No. The tax is an annual obligation that is included as a part of your regular property tax bill. Property tax bills are mailed to property owners in October, with first installments due November 1, and second installments due February 1.
