Measure AA

In June 2014, voters approved Measure AA, a 30-year, $300 million general obligation bond to protect natural and working lands; open preserve lands to the public; construct public access improvements such as new trails and parking/staging areas; and restore and enhance open space land, forests, streams, watersheds and coastal ranch areas.

MAA projects are grouped in 25 key project portfolios, organized by geographic area within District boundaries. Sales of bonds over the 20-30 year period generates the proceeds to fund the identified projects and allows the District to use property tax revenue for operational expenses, including maintaining preserves and trails, offering public programming and staff salaries. Midpen has also been able to leverage nearly $23 million in grants and partnership funding, plus $4 million in interest income from the bond proceeds to increase the total available MAA bond funding to $327.1 million, which helps in this era of rapidly increasing costs.

Join us in 2024 as we celebrate 10 years of progress made possible by Measure AA. Scroll down to explore more.

Measure AA Bond Accountability Report

The annual Measure AA Bond Accountability Report reflects MAA expenditures for the previous fiscal year. Expenditures, progress and major accomplishments within each of the 25 priority actions and project portfolios outlined in Measure AA, providing updates on project work completed within the fiscal year.

A Bond Oversight Committee (BOC) is appointed by the Midpen board of directors to ensure accountability, transparency and public oversight of all funds collected and allocated under MAA. The BOC consists of seven at-large members of the public who reside within District boundaries and review the Annual Accountability Report and expenditure plan in parallel each year, presenting findings to the board at a public meeting.

Measure AA Background

Measure AA is a 30-year, $300 million general obligation bond that was approved on June 3, 2014, by more than two-thirds of voters residing within District boundaries. Measure AA authorized Midpen to issue up to $300 million in bonds, at a tax rate not to exceed $3.18 per $100,000 of assessed value of property owned.

Midpen's goal is to invest the bond proceeds to:

protect natural open space lands
restore and enhance open space land, which includes forests, streams, watersheds and coastal ranch areas
open preserves or areas of preserves that are currently closed to the public
construct public access improvements such as new trails and parking areas

Due to legislative naming conventions, there are two conservation-related Measure AAs in the Bay Area. Midpen's 2014 Measure AA is not related to the San Francisco Bay Restoration Authority's 2016 Measure AA - San Francisco Bay Clean Water, Pollution Prevention and Habitat Restoration Measure, a $12 parcel tax that funds projects to protect, restore and enhance the San Francisco Bay. Depending on where you live, you may see both Measure AAs listed on your property tax bill.
