VLAS: Vacant Land Assessment System for Urban Renewal and Greenspace Planning in Legacy Cities

Vacant land in shrinking cities has long been associated with high crime rates and economic decline. While some efforts have made to repurpose vacant for tax revenue generation temporary environmental restoration, a comprehensive framework city-scale assessment reprogramming remains lacking. To address this gap, our study introduced the Land Assessment System (VLAS), multi-scale spatial analysis planning tool that assesses distribution characteristics of lots using publicly available data. Taking Hartford, Connecticut as case study, we assessed categorized into four typologies: Row House, Street Corner, Commercial/Industrial, Main Street. Responding reuse programs those typologies were generated one design example lot greening was also provided based on identified sustainable goals techniques. The VLAS serves an effective support tool, enabling efficient assessment, classification, urban vacancy management across city, district, neighborhood, site scales. This approach diverse physical offers valuable insights transforming other legacy sustainability neighborhood revitalization.
