Stormwater

A brief description of the innovative policy, practice, program, or outcome :

Earning over $2M of Federal and State competitive grants, WMU has gone above and beyond existing regulations in order to manage stormwater on campus, and its ultimate goal is to be stormwater neutral. Across campus, WMU has incorporated both retention and detention basins into the campus landscape providing retention basins for over 432 acres comprising 53.6% of campus as of 2012. These basins collect and retain water during periods of heavy precipitation and release it over time thereby reducing erratic flows, flooding, erosion, and generally improving the sustainability of our community and landscapes (on- and off-campus). Some of these basins are above ground and easily located, while others are below ground such as the massive infiltration basin beneath the Sangren Hall parking lot. WMU also showcases its dedication to proper management by partnering with other community stakeholders on stormwater programs within the Kalamazoo River watershed.

As a state-permitted storm water entity, WMU falls within the nonpoint source load allocation of a phosphorus Total Maximum Daily Load (TMDL) developed for the Kalamazoo River and Lake Allegan. To achieve the TMDL goal, loads were targeted in 2001 for a 43% reduction from April-June and 50% reduction from July-September.

A TMDL compliance plan documents that WMU has implemented best management practices (BMPs) and achieved total phosphorus (TP) load reductions sufficient to meet TMDL Load Allocation compliance goals. The plan also provides a ‘road map’ relative to implementation of on-campus and off-campus stormwater BMPs to move WMU into a position of becoming ‘Stormwater Neutral TM’.
