acps_redistricting's Issues

Make sure all buildings are accounted for

I suspect the district border is intersecting some buildings.

Export the disctricts again

Due to the change in tag name from boundary_level to admin_level for 2 relations (6603461, 6603481).

Fastest route may be outside the extent of the pgrouting area

population per districtblock is incorrect
