Mapping tools #1, #2 and #3 (DistrictR) have now been updated with the official population totals. Mapping tool #4 (Maptitude) still uses unofficial population estimates, but will be updated on October 27. There is no need to wait for the updates, submit your maps now and the demographic consultant can assist with population balance. Or revisit and revise your map after the official data is released.

The deadline to submit maps is October 18th; however, maps will continue to be accepted after the deadline. You are encouraged to submit your map as soon as possible. The final deadline for submitting maps will be determined by the Commission at its November 3 meeting—that deadline is likely to be near November 8.

Redistricting is different than most issues that come up in County government. Instead of being limited to saying you support or oppose a County-prepared ordinance or resolution, you can draw a map yourself!

There are different tools for different purposes, and different tools for different levels of technical skill and interest.

Submit maps to If you would like to submit a map created using your own software, please email to and include: (1) a GIS Shapefile and/or a Census Block equivalency file (using 2020 Census Blocks); and, (2) a description of the choices and key points of your map. After you submit your map, the demographic consultants will generate the population and other demographic details for your proposed map. Maps can be viewed on the Draft Maps page or on the Interactive Review Map.

Commenting on the maps you develop is also helpful. Comment features are built into Maptitude allowing you to submit comments and reference the map name you have created. For DistrictR maps, you can either reference the URL or the name of the map if you have created one and submit comments on the features of your map by visiting the Contact page or emailing
