New County Maps & New Districts
Congressional Districts
The new districts that will be used for the next 10 years have been released by the Citizens Redistricting Commission, and they include significant changes. The maps below explain the changes that will affect San Mateo County on local, state, and national levels. Many cities have also recently adopted by-district elections.
The primary election will be on Tuesday, June 7, and the deadline to enter the race is in March. The top two vote-getters will move on to November's general election. This final election will decide who will be in that seat for that specific district.

The eastern portion of the Peninsula will now be grouped as a congressional district from Daly City to Redwood City, including East Palo Alto. The coastal side will stretch from Pacifica to Pescadero, inland to Palo Alto and Mountain View, and downward towards Los Gatos and parts of San Jose.

SMC's Board of Supervisors Approve New District Lines
San Mateo County's Board of Supervisors approved the map above on Tue, Dec 7, 2021. Although the map has only minor changes, the Board of Supervisors will be changing significantly over the next two elections as the current board is prevented from running because of term limits. Supervisor Groom and Supervisor Horsely will term out in 2022. Supervisor Pine and Supervisor Slocum will term out in 2024.
