Data Sources & Methodology

Vacancy proxy: Properties with no active building permit for 3+ years in the Montgomery Building Permit Database (2014–present). Some inactive-permit properties may still be occupied — treat as an upper bound.

Crime correlation: ArcGIS Fire/Rescue/EMS incident data and MPD crime reports within 0.25 miles of each vacancy cluster over a 90-day rolling window.

AI recommendations: Generated by Claude claude-sonnet-4-6 on demand, using neighborhood name, vacant count, and nearby crime count as inputs. Advisory only — not a substitute for professional urban planning assessment.

Economic estimates: Modeled on comparable redevelopment programs from ULI and HUD Community Development Reports. Actual outcomes vary by execution and market conditions.
