Name: Storm Drain Discharge Point
Display Field: ID_OFPT
Type: Feature Layer
Geometry Type: esriGeometryPoint
Description: This point feature layer represents environmental outfalls maintained and managed by the Ada County Highway District (ACHD) in Ada County, Idaho. Each feature corresponds to an individual outfall structure and may include attributes such as structure diameter, structure type, ownership, land use, inspection, maintenance area and NPDES_Permit Area. Stormwater outfalls are critical endpoints of the ACHD drainage network, designed to convey collected stormwater runoff from roadways and infrastructure to receiving water bodies, channels, or infiltration areas in a controlled manner. The dataset is intended to support stormwater management, illicit discharge detection and elimination (IDDE), environmental compliance, water quality monitoring, asset management, maintenance prioritization, and MS4 permit reporting across the ACHD jurisdiction in compliance with National Pollutant Discharge Elimination System (NPDES) permit requirements. Data was compiled and is maintained by the Ada County Highway District.
Copyright Text: Created by Ada County Highway District, 2026. Outfalls data sourced from the highway district.
