The special tax, called Measure AA, achieved approval by 70% of the votes for the nine Bay Area county region at the June 2016 election, which is above the 2/3 legal requirement. The tax is $12 per parcel per year, for a period of 20 years. The first tax bills for this parcel tax will be mailed in September of 2017.

This special tax is levied on all parcels within the nine Bay Area counties. The parcel tax funds will be used to restore wetlands and do important work to preserve a healthy San Francisco Bay.

The tax is $12 per year per parcel, and there are no low income nor senior exemptions. This tax may not be prepaid.

Your county property tax bill includes a line item for this parcel tax. Additional information about the tax, the uses of the funds, and the Restoration Authority is available on the website The Authority is governed by a seven-member Board, and it has an Oversight Committee to ensure fiscal matters are handled appropriately.

The actual tracking of parcel data and the calculations are done by the Special Tax Administrator, which is a private company called NBS.


Exemption Application:

There are no Senior or Low-Income exemptions for the San Francisco Bay Restoration Authority Measure AA special tax.

An exemption is available for Contiguous Parcels that qualify.

Contiguous Parcels are mainly residential properties that are made up of more than one parcel due to division by Tax Rate Area boundary or properties that have the house on one parcel and a portion of the yard or the garage on a separate parcel. These parcels are considered one residential property, but because they consist of more than one parcel, will be subject to the Parcel Tax multiple times.
