The Development Intensity Zones (DIZ) geography as a block group-based assessment of existing development, largely formed from two analysis dimensions—density and proximity. Zones are classified from least to greatest development intensity.

Protected zones are within block group-based geographies but are removed from density and proximity index calculations. DIZ also uses the presence of structures (i.e. housing units, commercial and industrial square footage) to calculate these indices. The DIZ covers the 9-county DVRPC region, along with surrounding counties for greater context beyond the region.
