Text

Avg distance between intersections

Streets per mile

Best on all measures

Other indicators of potential



Areas already dense, diverse

• •

Multifamily zoning adjacent to SF zoning Mixed use – res parcels within 500 ft. of neighborhood businesses

Highest diversity by tract

Diversity/density variables

with potential centers

Final high priority areas

• identify center • zoning reform around center Density, mix, spatial definition

• connection – build connectivity to the center Streets and paths through existing dead space: • abandoned mall sites • parking lots • vacant lots • municipal owned lots
