Stormwater At a Glance
Sub-watershed Planning
Taking the lead for Partners for Clean Water, Co-Permittee Ada County Highway District (ACHD) has selected a consultant to work on Sub-watershed Planning to develop two sub-watersheds plans for Main Street (West Downtown) and Americana Blvd. The goal of the planning process is to identify locations where strategic planning and stormwater controls will improve water quality in the Boise River and meet stakeholder and NPDES permit objectives with efficient use of resources. The process includes a thorough analysis of the current built condition and hydrologic characterization followed by water quality modeling, stakeholder engagement opportunities, and prioritizing potential projects in the sub-watershed areas.
The Main Street and Americana Blvd. sub-watersheds were chosen for a number of reasons: 1. they discharge directly to the Boise River; 2. they have a potential for redevelopment and infrastructure improvements in the downtown and near downtown areas; and, 3. they have ongoing collection of outfall water quality monitoring data. The goal is to reduce discharge of polluted stormwater runoff by identifying potential opportunities for stormwater infiltration, evapotranspiration, rainfall harvesting/reuse, or other site-based Green Stormwater Infrastructure (GSI) practices.
