The mapping tool options linked below include different tools for different purposes and different tools for different levels of technical skill and interest. Residents can submit maps of the entire City, of one district or a specific community of interest, or of multiple districts. When using these tools, residents can group Census blocks together to form a district. Census blocks are the smallest population unit available when forming districts and therefore are considered the building block for district boundaries. To view the current district-based elections map, visit this Resources Page.

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.

It is helpful if you submit written comments with your map describing how your map was drawn to meet the required criteria. An example of this would be describing the specific neighborhoods or communities of interest that are kept within a single district.

The deadline to submit draft maps is February 1, 2022.
