Description
As part of the Potash Brook Flow Restoration Plan, a project was identified to retrofit an existing dry detention basin located on private property and divert runoff from a portion of Kimball Ave into the upgraded stormwater treatment practice.
Under current conditions, the existing stormwater treatment practice is not designed to modern standards and does not maximize phosphorus removal for the area draining to it. Additionally, the section of Kimball Ave in this area discharges directly to the stream with no treatment. By working together through a public-private partnership, the untreated runoff can be routed to the upgraded pond, where phosphorus removal can be achieved and stream channel flows reduced.
Funding
In 2024, the City received a grant funding from the Vermont Agency of Transportation for $44,000 to complete the engineering scoping study to evaluate the feasibility of the project, identify alternatives, potential issues, cost estimates and recommendations related to the retrofit of this stormwater treatment practice.
