A brief description of the institution's stormwater management initiatives:
The Pomona College Sustainability Action Plan sets an objective of increased use of sustainable stormwater management technologies for 2020 and identifies stormwater management as a main issue concerning water at the College. In its 2010 Open Space and Landscape Guidelines, the College outlines basic strategies for stormwater management: incorporation of unique site conditions into open space design, restoration of the Wash to its original function as a drainage basin, use of bio-retention basins or vegetated swales in newly created natural areas, reduction of impervious surfaces, use of permeable pavement wherever possible, the elimination of curbs and gutters, the use of large lawns as stormwater percolation beds where possible, and the transformation of surface parking lots into open and green spaces. All of the strategies in the Open Space and Landscape Guidelines have been adopted to some degree, including bioswales, pervious pavement, and an increase in total permeable open space on campus. The College is currently working on a significant stormwater management project that will redirect all stormwater from the northern part of campus into an underground filtration basin, reconnecting this water with the natural aquifer.

Does the institution have porous paving?:
A brief description of the institution's porous paving:
Porous paving has been utilized across campus, including the use of Turfcrete, decomposed granite, and other permeable surfaces.
Does the institution have retention ponds?:
A brief description of the institution's retention ponds:
The campus does not receive enough rainfall to permanently fill a retention pond, but does make use of designed detention basins within landscaping to collect water after a storm and reconnect that water with the natural aquifer.
Does the institution have stone swales?:
A brief description of the institution's stone swales:
Does the institution have vegetated swales?:
A brief description of the institution's vegetated swales:
Vegetated swales are used in a number of places on campus to temporarily collect and channel stormwater runoff into basins that drain into the natural aquifer. An extensive system of new swales is also currently under construction for the southeastern corner of campus.
Does the institution employ any other technologies or strategies for stormwater management?:
A brief description of other technologies or strategies for stormwater management employed:
The College has a long-term plan to significantly reduce the area of concrete and asphalt surfaces on campus, which will significantly alter the path of stormwater on campus. Runoff will be channeled into retention basins, pervious pavement areas, and swales.
