A brief description of the institution’s green infrastructure and LID practices:
North Seattle College adheres to the City of Seattle's Stormwater Management Plan and the stringent regulations it sets forth:
"Storm-water Management Plan (SWMP)
The City of Seattle SWMP will address the following permit requirements:
• Protect water quality
• Reduce the discharge of pollutants to the “maximum extent practicable”
• Satisfy appropriate requirements of the Clean Water Act
• Meet state requirements to use all known, available, and reasonable methods to prevent and control pollution to waters of the state.
The Stormwater, Grading and Drainage Control Code (SMC 22.800-22.808) and associated Directors’ Rules are being revised to account for advances in urban stormwater runoff management practices. Changes and updates to the code are being made to make it equivalent to the 2005 Washington Department of Ecology’s Stormwater Management Manual for Western Washington. This is a requirement for compliance with the Municipal Stormwater NPDES Permit, which was issued January 17, 2007. Visit the Department of Planning and Development's website to learn more about the code revisions."
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.
