In 2004, the Center underwent a master plan planning process in order to outline areas of program growth and habitat restoration initiatives. The planning process identified Best Management Practices (BMPs) to reduce water volumes and improve the quality of outflow into Saw Mill Run, including: 1) Porous asphalt parking lot; and 2) Bioswale. 1) Porous Asphalt
Parking Lot The underlying recharge bed stores water and allows it to percolate. During construction, soil below the storage bed was loosened at the natural substrate level to allow for greater infiltration and aquifer recharge. This has improved water table levels and calmed water velocity in the vicinity. This stormwater BMP has had a positive effect on Saw Mill Run. Erosion has subdued and aquatic diversity is improving. Pollution (e.g. nutrients and heavy metals), trash and sediments are filtered by the porous asphalt, and thus are prevented from entering Saw Mill Run. Spring Mill Road was re-contoured on one side to capture run-off as well. 2) Bioswale The bioswale plant list
(including shrubs, trees, and seed mixes), and planting sequence are
available here. |
