The High Line Canal Stormwater Transition and Management Plan (STAMP) Study entitled “Guiding a Regional Stormwater Transition” received the 2026 APWA Colorado Chapter Award for the Administration category!
ICON collaborated with project partners to assess flood risk and develop prioritized mitigation solutions for the entire 66-miles of the High Line Canal. 27 improvement concepts were created and evaluated across multiple categories (conveyance, bank manipulation, treatment drains, and capacity increases), which were quantified by their effectiveness, estimated costs, and benefits. Our staff also produced risk rankings, conceptual designs, and an interactive GIS tool to help agencies visualize and prioritize projects. In addition, ICON supported coordination with stakeholders and provided guidance on maintenance, permitting, and long term adaptation, helping frame the canal’s transition from an irrigation system to a stormwater management asset.
Congrats to the Mile High Flood District, Southeast Metro Stormwater Authority, High Line Canal Conservancy, and the study team that made this project a success!
