the campus Stormwater Plan, opportunities to intervene in this system will be evaluated <br />and implemented. Specific techniques to intercept stormwater nmolT that can be <br />incorporated into the landscape include the following: <br />Woodland Berms <br />Woodland Benns provide an opportunity to intercept runoff from upsU-eam development <br />os it runs down the hillside. Shallow berms constructed along the contour collect and <br />intercept the runoff, preventing erosive conditions and providing the infiltration <br />necessary to maintain existing woodlands. Often, existing woodlands can die off when <br />uphill development prevents infiltration and the soil moisture is reduced. Woodland <br />benns address this issue and reduce the runoff impacts. This measure can be <br />implemented within existing sloped wooded areas that are to be protected. <br />Infiltration Bed <br />An Infiltration Bed. consisting of a stone storage/recharge bed beneath plantings, con be <br />used within the landscape to collect and store/infiUrate runoff from existing buildings, <br />parking areas, and roads/sidewalks. This is an inexpensive option that can be <br />incorporated within the existing campus areas to reduce stormwater impacts. A stone <br />storage/infiltration bed can be located beneath landscaped areas or playfields. The 18 <br />inches of soil above the bed allows for landscaping and plantings. <br />Infiltration french <br />An infiltration trench is essentially a storm sewer that is designed to leak. A perforated <br />pipe is set in a bed of stone wrapped in filter fabric, with soil and a surface swale located <br />above the pipe The trench should run along the contour or nearly level to allow <br />infiltration to i>ccur along the length of the trench, infiltration trenches provide an <br />opportunity to store and infiltrate runolT in areas where there is not a lot of available <br />space, such as adjacent to roadways and parking areas, or between parking spaces. <br />Porous Concrete <br />Porous Concrete is similar to porous bituminous asphalt in that the fines are held to a <br />minimum, allow mg w ater to pass through the concrete to a stone bed beneath. Porous <br />concrete is ideally suited to sidewalks, provided an opportunity to store infiltrate <br />stonnwater in areas where there is limited space available. <br />Cahill Associates <br />Environmental Consultants <br />i <br />. .i <br />f ■ ■ •'
