Does the institution have a policy, plan, and/or strategies to reduce stormwater runoff from new development projects? :
Does the institution have a policy, plan, and/or strategies to reduce stormwater runoff from ongoing campus operations? :
A brief description of the institution's stormwater management initiatives:
Focused on restoring the campus storm water runoff to pre-development conditions. Our intent is to reduce stormwater runoff to the level experienced in 1960 just before the University was established. These efforts include porous pavement parking lots, rain gardens, green roofs, wetland creation and storm water reuse in campus irrigation.

Does the institution have a living or vegetated roof?:
A brief description of the institution's living or vegetated roof:
Green roofs promote infiltration of storm water and reduce peak runoff from storm events. The sedum plants absorb and uptae storm water runoff and reduce pollutant loadings. These roofs are located on the Kennedy Engineering Building, the Honors College Building, portions of the South Living Center, the Connection Building, the MAK 2008 Addition, the AWRI Boat Storage Facility, and portions of the Kelly Sports Facility. Green roofs are being designed for a new science lab building.
Does the institution have porous paving?:
A brief description of the institution's porous paving:
We have both sidewalks and 2 parking lots that used these materials.
Porous pavement promotes infiltration of storm water and reduces peak runoff from storm events. Storm water is captured through the pavement and a system of underdrains and underground cisterns.
Does the institution have retention ponds?:
A brief description of the institution's retention ponds:
Storm water detention-reuse ponds capture storm water from a large portion of campus. The water is captured, stored and reused in the campus irrigation system or allowed to flow through a more natural pace to the Grand River. In addition, we recently completed a stormwater management complex that is 55 acres in size and designed to manage a significant area of existing pavement and buildings.
Does the institution have stone swales?:
A brief description of the institution's stone swales:
These are located in ravine where stormwater is causing aggressive erosion. These are temporary measures until a more suitable solution is constructed. Our efforts concentrate on the removal or reduction of stormwater flows through the ravines as an initial effort; this is then follow by reconstruction activities.
Does the institution have vegetated swales?:
A brief description of the institution's vegetated swales:
The university has created numerous rain gardens to promote infiltration and reduce pollutant loadings. In addition, we have these devices in manicured lawn areas as an initial collection feature. Design solutions fo rnew buildings seek to incorporate existing older stormwater management solutions into the new site deisgns; the intent is to update the older solutions to current best management practices. These newer design solutions invariably seek to detain the stormwater flows for a greater period of time to allow sediment to drop out of the stormwater flow.
Does the institution employ any other technologies or strategies for stormwater management?:
A brief description of other technologies or strategies for stormwater management employed:
Wetland system construction captures, stroes and treats stormw water through a series of sediment fore-bays and stormwater management cells. Our newer recreation and sports fields are constructed with stormwater acollection and storage facilities located below the playing surface. Where feasible, we re-direct historic flows from parking areas to newer or reconstructed detention areas to allow greater non-source pollutant removal.
