Research notes
Applies to municipalities with population ≥70,000. Requires minimum lot size ceiling of 5,000 sf in the majority of single-family zones. Tribal lands excluded. Federal conflict check flags conflicts with MAAMF / AFB overlays that may restrict residential density on the same base_districts[*].
