Draw and Submit a District Map

Districting is different from most issues that come before the City Council. Instead of being limited to saying you support or oppose a City-prepared ordinance or resolution, you can draw a map yourself!

What criteria should I use?

Many factors may be considered, but population equality is important.  In a seven-district map, the ideal district population is 24,973, so the largest and smallest districts must be within 2,497 of each other in total population (roughly between 23,724 to 26,222).

Other factors may include – communities of interest, must be compact, contiguous, have visible (natural and man-made) boundaries, plan for future growth, etc.

To better visualize where Population Unit boundaries are located, refer to:

Census Block ID Number of Population Units

Census Block of Total Population by Population Units

OPTION 1:  Paper-Only Maps

You can use the simple one-page map to draw your proposed districts and calculate the total population.

OPTION 2:  Microsoft Excel Supplement 

Are you familiar with Microsoft Excel? If so, you can let Excel do the total population and demographic math for you. You can save the Excel file to your computer. Then use the Excel file and the “ID Number of Population Units” map to assign the Population Units to your desired districts, and Excel will provide the resulting demographics for each district. 

OPTION 3:  Online District-Drawing Tool

The most powerful map drawing tool, but also the most difficult to use, is the online district-drawing tool (Draw Maps Online). This tool enables you to draw districts census block by census block, just like the professional demographers. You can fine-tune your district lines and see, in detail, the resulting demographics as you draw your map.
