Arapahoe County Elections welcomes public comment for precinct renumbering

County adjusts precinct numbers and boundaries to align with new U.S. and state maps


Jan. 3, 2021—The Arapahoe County Clerk and Recorder’s Office is seeking public comment before presenting new precinct maps to the Board of County Commissioners for final approval.


The Elections division within the Office is legally responsible for updating precinct boundaries and numbers every 10 years, to reflect new United States Congressional and Colorado legislative districts. Federal and state districts are updated every decade using United States Census Bureau data. The process is nonpartisan, with Colorado county mapping and elections professionals calculating active voter counts and adjusting district lines and new numbers where necessary.


Precincts in Arapahoe County will increase from 399 to 409 total. Most precincts will not have new boundaries, but almost all of them will have modified 10-digit identification numbers.


Other details:

  • 36 precincts had no changes numerically or geographically;
  • 318 precincts had no physical geographic changes, but require their full precinct number be changed due to a combination of a new U.S. Congressional, Colorado Senate and/or Colorado House district boundaries being drawn by the Colorado Independent Redistricting Commissions;
  • 57 precincts were modified geographically. These were split apart from larger precincts, had parcels split from them, or had portions of other precincts merged into them.


In addition to boundary changes based on new district lines or active voter counts, most County precincts will have their 10-digit identification number updated to match new U.S. Congressional or state legislative districts.  


Precinct boundaries cannot conflict with Congressional, House and Senate District boundaries recently created by the Colorado Independent Redistricting Commissions and approved by the Colorado Supreme Court. Precincts are also limited to no more than 2,000 active voters each. 


County residents may view current and proposed maps, and provide comment on the proposed maps at Interactive story maps on the webpage allow users to compare previous borders to proposed new boundaries. Users can also view individual PDF precinct maps organized by various districts. 


The Arapahoe County Board of Commissioners must approve a new precinct map before Jan. 31, 2022. The public comment period ends at 11:59 p.m. on Tuesday Jan. 11, 2022.


This process has no bearing on the redistricting process for County Commissioner districts. That process, beginning in 2023, will potentially adjust commissioners’ district boundaries based on U.S. Census population data.
