• Bill 55-25 replaces the existing 7-district map with a new 9-district map for County Council representation, effective for the 2026 and 2030 County Council elections.

• The bill includes two key exhibits:

  • Exhibit A – the proposed map with boundaries for nine Council districts.

  • Exhibit B – a Population & Demographic Summary showing population and racial/ethnic breakdowns by district under the new plan.

• Until the new Council members are sworn in after the 2026 election, the current 7-district boundaries remain in effect for constituent services.

• The expansion from 7 to 9 districts and subsequent redistricting was required by a prior charter amendment passed in 2024. Baltimore County

• The redrawing was based on data from the 2020 U.S. Census, to ensure that districts have roughly equal population in compliance with legal requirements. countycouncil.baltimorecountymd.gov

• According to the Council and supporters, the new map reflects public input gathered during hearings, aims to strengthen representation for historically underrepresented communities, and attempts to avoid partisan or incumbent-based gerrymandering. countycouncilweb.s3.amazonaws.com

The new 9-district map takes effect for the 2026 County Council election (and remains in effect through 2030). Until then, the existing 7-district map remains in force for constituent services.

Not necessarily, it depends on where you live and how the boundaries shift under the new plan. Some residents may remain in equivalent areas even under a new district number; others may find they are now in a different district, or grouped differently with neighboring communities.

The expansion was mandated by a charter amendment approved by voters in 2024, with the aim of improving representation as the county population grew.

• Check your address. Look up the new district boundaries on the interactive map and see which of the 9 districts you fall into after the redistricting.

• Share with neighbors. Not everyone may be aware that district boundaries have changed. Sharing the map and FAQs helps ensure people know who will represent them going forward.

• Stay informed. Monitor the Council’s website for updates about when constituent services transition to the new districts, and any resources to help residents adjust.
