A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:

Seattle Central 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 Seattle Central's campus comply with these stringent codes, with many featuring stormwater retention tanks or detention features such as rain gardens.

Furthermore, Seattle Central 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.
