Which of the following best describes the institution’s approach to rainwater management?:
Comprehensive policies, plans or guidelines that require LID practices for all new projects

A brief description of the institution’s green infrastructure and LID practices:
The University has implemented several strategies to enhance percolation of stormwater run-off into the groundwater aquifer and reduce the quantity of run-off from entering the stormwater system. For new construction, the runoff from the roofs is directed to planter areas. For existing buildings, the University has disconnected the downspouts from the stormwater piping system. This allows the run-off to sheet-flow and percolate into the groundwater aquifer before it enters the stormwater system. The University is converting the grounds adjacent to buildings to planter areas so that the hydrological retention time is increased. When the University initiates a capital construction project (either new or renovation), the general contractor is required to take the necessary actions to prevent all construction-related activities from contaminating ground water runoff from entering the storm drain system. The campus has also actively been replacing impermeable surfaces with permeable pavers, landscaping, and decomposed granite to enhance stormwater percolation and reduce runoff.

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:
CSUCI address rainwater management in several campus plans, including the campus Master Plan and the Vision Plan. Each of these plans provides guidelines for incorporation of rainwater management features such as bioswales, rainwater gardens, cisterns, permeable pavers, and other strategies to reduce stormwater runoff.

CSU Channel Islands is regulated as a non-traditional Small Municipal Separate Storm Sewer (MS4) permittee under the State Water Resource Control Board's Phase II Small MS4 General Permit. In addition to the rainwater guidelines outlined in the aforementioned plans, the university has a MS4 Phase II Program Plan to reduce pollutants in stormwater discharges and to meet total maximum daily load (TMDL) requirements. The Program Plan identifies existing and planned best management practices that have been or will be implemented to achieve compliance with the wasteload allocations for applicable TMDLs in the Calleguas Creek Watershed.
