UNIVERSITY OF MISSOURI 2015 STORMWATER MASTER PLAN AUGUST 2015 MU Projects Goals Address Stormwater The University of Missouri Stormwater Master Plan provides As water flows downhill off campus, it collects in Flat Branch an adaptable framework that and Hinkson Creek. Greater quantities of water gather and enables the campus community flow to those streams when traveling over impervious surfaces to improve stormwater quality, such as asphalt or rooftops than it does if soil absorbs the rain. maintain regulatory compliance and Because of this effect in urban environments, heavy storms sustain water resource stewardship. cause flash flooding in local waterways. MU implemented This overall goal is energized by the Stormwater Master Plan in 2012 to set goals and provide Mizzou’s leading research and guidance for future development on campus. innovation engine, a key asset in Flooding is not the only problem. “The faster stormwater developing solutions to evolving moves, the more pollutants it picks up and the opportunity for stormwater challenges. infiltration is reduced,” says Jennifer Sullivan, facilities project manager. Soil on campus might erode away, as might creek beds downstream. Extra sediment and water heated by pavement may change stream habitats.

Sizing BMPs to effectively capture runoff will reduce BMP Research pollutants through filtration, uptake and settling processes. An initial BMP- sizing goal is to capture or treat 80 percent of post-construction runoff.

Recent BMPs East Campus Stormwater 1 Constrained Situations Areas that are highly developed have fewer Modeling Case Study opportunities for BMPs than open areas. A limited footprint of distributed BMPs for MU engineers are using sophisticated computer models stormwater control is achievable in constrained to guide stormwater planning for new and redevelopment settings. projects. A 150-acre watershed located in east campus was selected as a case study area.
