Description: This polygon feature layer represents environmental tree cells maintained and managed by the Ada County Highway District (ACHD) in Ada County, Idaho. Each feature corresponds to an individual tree cell installation and include attributes such as tree cell identifier, location, street name, installation year, condition rating, inspection date, and maintenance jurisdiction. Tree cells are engineered green infrastructure systems that combine urban tree planting with stormwater management, utilizing structured soil cells beneath paved surfaces to support tree root growth while capturing, filtering, and infiltrating roadway runoff. They are designed to improve water quality, reduce stormwater volume, enhance urban tree canopy, and contribute to livable streetscapes in compliance with National Pollutant Discharge Elimination System (NPDES) permit requirements. The dataset is intended to support stormwater management, environmental compliance, urban forestry, green infrastructure planning, asset management, and maintenance prioritization across the ACHD jurisdiction. Data was compiled and is maintained by the Ada County Highway District
