Ball State University
OP-23: Stormwater Management

Construction site stormwater water management plans are submitted to Delaware Soil and Water District for review prior to start of construction. Practices include: *All new or renovation projects must have all drains and catch basins clearly labeled with "No Dumping Drains to River". *Daily sweeping of streets and drives *Weekly site inspections *Truck tire washing below leaving construction site *Concrete wash area *The elimination of straw bales as "best management practices" and replaced with drain inserts, filter fabric and compost socks. *On-going campus operations - stormwater management practices include: *Weekly scheduled sweeping of streets, parking lots and service drives *Catch basins are cleared of debris each month *Elimination of sand in snow and ice removal operations.

Ball State University installed its first living vegetated roof on the university’s new geothermal transfer station (North District Energy Station) to help with energy efficiency and water drainage. The project was completed in July 2011 and it was implemented by Weston Solution Green Grid roof company, an outside contractor. The plantings had a minimal depth tray system utilizing sedums as the primary plants. The green roof is about 7,000 square feet of vegetation. Facilities Planning and management is considering adding additional green roofs on other campus buildings.

Ball State University for the past several years has included porous paving areas in its development projects. Including the stadium , Carmichael, Kinghorn Hall, and the baseball parking lot renovations, approximately 7,200 square feet of porous pavers has been used. Future plans call for porous pavers to be used in additional renovation projects.

Ball State University has several holding ponds on campus. The first pond is located at Park Hall and collects stormwater from roughly a quarter of the campus. The pond includes a recirculation pump and fountain for oxygenation and aesthetics. The water from the Park Hall pond flows through a native vegetated creek which empties into a smaller pond. The second pond flows over a series of rocks and connects to a third campus pond. The third pond is designated a true retention pond holding water and slowly allowing water to flow into the White River and the Yorktown-Prairie Creek Reservoir.

Ball State University utilizes several vegetated swales throughout campus which help slow down the speed in which rain water drains into the local watershed and helps prevent local flooding after a heavy rainstorm. The first vegetated swale is located at Cardinal Creek at Park Hall and slowly empties into Duck Pond. The Glick Center swale is planted to a prairie grass mix that only needs moved several times per year. The Kinghorn Hall swales drains into the Cardinal Creek swale to help eliminate or reduce sedimentation discharge in the local watershed.

The university uses a street sweeper daily starting mid-March through early November to remove sediment and debris off of campus streets, drives and parking lots.
