Sucker Brook Stream Stabilization

Williston, Vermont | Town of Williston

Sucker Brook was a deeply incised stream channel that threatened nearby infrastructure and sent an estimated one ton of phosphorus per year downstream toward Lake Champlain. The project goals included a reduction of sediment loading and erosion and the restoration of aquatic and riparian habitat while minimizing construction and maintenance costs. D&K prepared conceptual and final design of alternatives, stability analysis, H&H analysis, a public presentation, completed permitting applications, and an evaluation matrix comparing alternatives in terms of reduction in sediment loading, long-term stability, construction and maintenance costs, in-stream and riparian habitat, and impacts to adjacent landowners. The project team’s final design included a step-pool reach with eight stone weirs and a detailed planting plan to restore the riparian zone.

Project Elements

• Restoration design to address an unstable channel at the bottom of 40-ft gully
• Limited construction funding led to development of two-year construction sequencing and support from volunteer labor to accomplish the planting program.
