Abstract:
This presentation discusses the Mile High Flood District's evolving approach to nature-based urban waterway design – an approach they’ve been experimenting with for over 10 years. The presentation emphasizes a shift from solely focusing on flood protection through hydrology and hydraulics to more holistic, nature-based designs that incorporate geomorphology, vegetation, and multiple community values. The urban context presents special challenges related to geomorphology and hydrology that require a balance of systems thinking, community input, and judgment to improve waterways corridors in a way that will optimally balance flood mitigation, ecology, and community. Example projects will be shared to illustrate the dynamics, considerations, and long-term outcomes including how some of our projects fared during the 2013 Colorado floods.
