CA state senate district boundaries and current membership. Boundaries are valid for sessions starting in 2025 and through 2030.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This is the last boundary change until the next redistricting following the 2030 Census. All of the districts now reflect the 2021 Citizens Redistricting Commission(CRC) plan. The only thing that will change is the members' names and parties as elections are held, appointments are made, or party affiliations change. Senate Districts feature layer is updated as-needed and we expect to update it more regularly in the future. </SPAN></P><P><SPAN /></P></DIV></DIV></DIV>
