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:
The 2026 Campus Plan includes a sustainable campus stormwater management plan that establishes a framework to guide the continued restoration of the main campus stormwater systems, including protecting and enhancing existing natural resources and promoting a water balance approach for all campus development projects using green infrastructure and LID practices. The campus expansion to the undeveloped lands provides an opportunity to redevelop the open space using an ecological approach that preserves the quality and value of the lands and goes beyond simply mitigating adverse impacts.
The comprehensive stormwater approach includes a combination of ecological restoration projects and stormwater projects and retrofits at both the site- and district-scale. Strategies for reducing the volume and rate of rainwater/stormwater runoff and improving outgoing water quality include green roofs, bioretention and rain gardens, subsurface infiltration, storage under athletic fields, porous pavement on paths and in parking lots, and manufactured treatment devices (ex. jellyfish, and other inlet filtration devices). Recent building projects have also incorporated rainwater and condensate harvesting systems for reuse in toilets. District-scale strategies include a combination of on-site green infrastructure and green infrastructure corridors which overflow to centralized ecological treatment landscapes.
Since 2006, these stormwater improvement efforts have been implemented on more than 100 acres of campus, reducing annual stormwater runoff by 23 million gallons over this time frame.
