Sub Watershed Plans


Sub-Watershed Planning

The Boise/Garden City Phase 1 MS4 Permit requires the completion of Watershed Management Plans for drainage areas served by the MS4 no later than September 30, 2016.  The co-permittees determined that the Main and Americana sub-watersheds, located in Downtown Boise, were appropriate for sub-watershed planning.  The Ada County Highway District, on behalf of the Partners, has completed the development of the plans.
