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:
San Francisco currently has two projects related to green infrastructure and LID practices. From Sky to Soil is our flagship rainwater harvesting system that collects 12,000 gallons of rainwater each year from the roof of the Recycling Center. We are utilizing an adjacent 630 watt solar array to power a pump to irrigate over 6,000 square feet of native plants until they become established. We will then redirect the water to other new landscaping projects.
Sky to Soil also includes our first rain garden installation collects about 60,000 gallons a year from the adjacent Corporation Yard warehouse roof. This rain garden was planted with native plants that are both drought tolerant, and can handle short periods of inundation of water in the winter.
Our second project is the Science Corridor Bioswale which replaces 1600 square feet of resource-intensive lawn that now captures 60,000 gallons of the rainwater per year that falls on the Science Building roof and channels it into a vegetated swale. A variety of locally native plants now attracts birds, bees, and butterflies.

SF State's Mashouf Wellness Center was built using these practices. It uses rainwater for irrigation and contains permeable surfaces intended to drastically reduce stormwater runoff. http://cpdc.sfsu.edu/mwc-water

A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:
SF State's Water Resources Management plan integrates water use, reuse, and groundwater infiltration on campus. Water that falls on rooftops, sidewalks, and roadways can be channeled into water tanks, to be used for irrigation during our dry months, or into rain gardens (planted depressions in the landscape) for passive groundwater infiltration. SF State's "From Sky to Soil" Project includes a series of rain gardens, bioswales, and rooftop rainwater collection.
