Description

Runoff from the terraced yard and impervious surfaces at the Rumney School campus in Middlesex, Vermont had created a gully and formed an outfall, which was causing significant erosion, sediment deposition, and bank instability in Martin Brook (locally known as Shady Rill). The Winooski Natural Resources Conservation District spearheaded a two-phase project to address this issue, in partnership with several organizations and with support from two Ecosystem Restoration Grants.

Phase 1 focused on the initial design of the project, which included assessing and mapping existing site conditions, developing conceptual designs to address the stormwater concerns, selecting the optimal design, and completing 30% of this final design.

Phase 2, supported by a second Ecosystem Restoration Grant, focused on the project's implementation. This phase included soliciting school, student, and parent input into the final design, completing the final design, and constructing the stormwater mitigation project using green infrastructure.

In addition to mitigating the detrimental impacts on Martin Brook, this project now serves as an ecological learning laboratory for the school's students.  

Project Outputs

  • 1.5 acres of impervious area treated
  • 4.5 total acres treated

Implementation 

Description

Green stormwater infrastructure was constructed to infiltrate stormwater runoff and minimize erosion issues through a series of step pools. The project also stabilized a head-cut on a road drainage culvert and restored an eroded gully.

Project Outputs

The green stormwater infrastructure bioretention area on Morey Road accomplished:

  • 4.4 acres of impervious area treated
  • 19.5 total acres treated

Environmental Outcomes

The green stormwater infrastructure bioretention area on Morey Road accomplished:

  • 3.7 kilograms of phosphorus reduced annually
