Sterling College (VT)
OP-23: Rainwater Management

Ninety percent of our 480 acre main campus and 100% of our 307 acres of off campus property is open space and includes forest, grassland, and wetlands which serve to capture much of the community’s stormwater runoff. The college’s total impervious surface (parking areas, walkways, roofs) is only 1.8 acres of our 480 acres, but we are very conscientious of our stormwater runoff. As we continue to grow as well as renovate our buildings and infrastructure, we are intentional about locating new construction to contour with the landscape, using Low Impact Development (LID) and Green Stormwater Infrastructure (GSI) such as drip line trenches which discharge into natural swales.

Wetlands play a critical role in stormwater retention and filtration and over 350 acres of the college campus are State and National Designated Wetlands, including the Northern White Cedar Swamp on the main campus and Bear Swamp in Wolcott, Vermont. These wetlands are protected by law and not only provide valuable ecological services, but are important natural areas for conservation and natural history research at the college. Several of Sterling College buildings stormwater runoff feeds into existing drains which flow through a main culvert into a small ditch managed by the town. This ditch travels 100 yards to a larger ditch alongside our significant wetland complex. Stormwater is naturally filtered through this area and then slowly migrates down slope for half mile towards the Black River. A recent survey of the Black River resulted in no significant impact from this practice.

Sterling College is located in Craftsbury Common, a rural hilltop village which is sits on relatively shallow soils and bedrock and in the headwaters of the Black River. Stormwater is an issue for the broader community and Sterling’s land base plays a significant role in the town management of runoff from rain events and snow melt. The Sterling College overall mission reflects our commitment to land and water quality through sustainable and innovative land use practices.

Sterling College is currently working with the Natural Resource Conservation Service (NRCS) to develop a Nutrient Management Plan (NMP) for the barns in our Rian Fried Center for Sustainable Agricultural and Food Systems. This plan will help us capture runoff and ensure there is no nutrient loading into nearby waterways.

A recent survey of the Black River resulted in no significant impact from this practice. The Sterling College Lands and Energy Committee is revamping the Sterling College Land Use Plan and there will be a more specific stormwater management plan associated with the overarching plan. This will be an opportunity for the college community, including faculty, staff, and students, to reevaluate our current LID practices and plan for the implementation of the latest GSI techniques available to our region and landscape.
