Which of the following best describes the institution’s approach to rainwater management?:
A brief description of the institution’s green infrastructure and LID practices:
Underground detention system for runoff from south parking lot and Olympic building roof filters runoff before entering storm drain. For roofs and landscapes there are 4 tanks (capacity of 1k-2k gal/tank) all underground. Tanks are inspected annually. There are several rain gardens throughout campus to slow and absorb rainwater.
The Georgetown Building C Expansion, Gene J. Colin building is certified LEED silver. Some green infrastructure was included in that project, including bioswales surrounding the parking lot to collect and slow-down runoff.
There are several green infrastructure installments at South Seattle. A natural bioswale, designed to capture stormwater for irrigation, is included in the landscape of the University Center building. At the Georgetown campus, there are natural bioswales to control stormwater and a green roof. There are several rain gardens on main campus, including one for the University Center, two around the Chan building, and one at Cascade Hall.
A copy of the institution’s rainwater management policy, plan, and/or guidelines:
A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:
South Seattle College is located within the City of Seattle, which mandates the use of low-impact development practices through its Stormwater Municipal Code (Title 22, Subtitle VIII). The code requires stormwater discharge be appropriately managed on parcel-based projects through soil amendment, on-site stormwater management, flow control, and water quality treatment. All buildings on South Seattle's campus comply with these stringent codes, with many featuring stormwater retention tanks or detention features such as rain gardens.
Furthermore, South Seattle College has made a commitment to building all future buildings and major renovations to LEED Silver standards. The USGBC LEED credit for rain management intends, [t]o limit disruption of natural hydrology by reducing impervious cover, increasing on-site infiltration, reducing or eliminating pollution from stormwater runoff and eliminating contaminants." Low Impact Development (LID) is one strategy used to achieve this LEED credit and intent, among others.
