A variety of public mapping tools are available to assist the public in drawing maps. There are different tools for different purposes and different tools for different levels of technical skill and interest.

Now Available:

1. Paper-only maps for those without internet access or who prefer paper.

2. Paper maps with a Microsoft Excel spreadsheet to calculate population totals

    • Public Participation Kit – Paper Map w/ Population ID#s (in English or Spanish)

3. Dave’s Redistricting (DRA 2020) – a free web app to create, view, analyze and share redistricting maps.

    • Sign up
    • “How To” guide
    • Video tutorial
    • Use DRA 2020 to draw Marina City boundaries.
    • IMPORTANT NOTE: Include “Marina City” in your map name. To submit your map, send an email with a link to your map to redistrictingmarina@cityofmarina.org. You can use the Share button at the top of the map page to generate a link to your map. If you do not email your map, it will not be entered into the public record for consideration. 

4. DistrictR – has been replaced with Dave’s Redistricting App.

    • IMPORTANT NOTE: DistrictR used population estimates; Dave’s Redistricting App uses the official California prisoner-adjusted population. Those who previously submitted under DistrictR are encouraged to redraw using Dave’s Redistricting App for population balance.  The archive DistrictR Gallery can be viewed here (to view the Gallery, scroll down after opening the page, but do not use this mapping tool for drawing maps).

5. Interactive Review Map – to review, analyze, and compare maps, not to create them. Zoom in and out on map boundaries, view population counts/ID#s, and view draft maps (once the draft maps are released). Similar to Google Maps in ease of use.

If you would like to submit a map created using your own software, please email to redistrictingmarina@cityofmarina.org 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.

Submit maps to redistrictingmarina@cityofmarina.org. 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.

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.
