description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN STYLE="font-size:14pt">This polygon feature layer represents environmental basins maintained and managed by the Ada County Highway District (ACHD) in Ada County, Idaho. Each feature corresponds to an individual basin and may include attributes such as subdivision, location, year built, jurisdiction, maintainer, HOA, storage type, stormdesign_yr, receiving waterway, instrument, basin type, project, project number, vegetated, intersection parcel no, city, gatetype, fencetype, NPDES_permitArea and maintainer. Environmental basins are a critical component of ACHD's stormwater management infrastructure, designed to manage runoff, reduce flooding, improve water quality, and protect downstream waterways in compliance with National Pollutant Discharge Elimination System (NPDES) permit requirements. The dataset is intended to support stormwater management, environmental compliance, asset management, maintenance prioritization, and infrastructure planning across the ACHD jurisdiction. Data was compiled and is maintained by the Ada County Highway District.</SPAN></P></DIV></DIV></DIV>
