A stormwater outfall just southwest of Elm St drains into a ravine that flows into wetlands within the Winooski River floodplain. Flow from the outfall was dropping into a channel before draining into the ravine. The drop below the outfall is several feet, and, prior to retrofit, the channel surface was bare soil. As a result, flow from the outfall was eroding the channel, sending sediment into the ravine and the downstream wetlands. The goal of the project was to develop a final design to stabilize the channel with geotextiles and controlled fills and raise grades below the outfall to dissipate energy during flows. The project required building temporary access to the channel and associated temporary erosion control measures. The project will reduce erosion from the channel and reduce sedimentation of the downstream wetlands. NOTE: Using this design, the City then constructed this stabilization project in the fall of 2020 using a VTRANS Better Roads grant along with City funds.

The CCRPC selected Watershed Consulting Associates (WCA) for initial scoping, assessment, alternatives analysis, and 30% design development for the replacement of two (2) culverts on Densmore Drive in Essex Junction, VT.

The intent of this report is to present the data collected, evaluations, analyses, designs, and cost estimates for subwatersheds in Underhill under a contract between the Chittenden County Regional Planning Commission and Watershed Consulting Associates, LLC. Funding for the project was provided by a Vermont Department of Environmental Conservation, Clean Water Fund grant. The plan presented is intended to provide the watershed’s stakeholders a means by which to identify and prioritize future stormwater management efforts. This planning study presents a recommended collection of Best Management Practices (BMPs) that would address specific concerns that have been raised for these areas. In particular, there is great need to reduce stormwater impacts including phosphorus and sediment from stormwater runoff to receiving waters within the Town and the greater Lake Champlain Basin in light of future regulation under the Lake Champlain Total Maximum Daily Load requirements. Although there are other BMP strategies that could be implemented in the watershed, these are the sites and practices that project stakeholders believe will have the greatest impact and probability of implementation. These practices do not represent a regulatory obligation, nor is any property owner within the watershed obligated to implement them. This stormwater master plan, and therefore its resultant strategies, will be one of the actions in the Lamoille Tactical Basin Plan. This will put the BMP strategies in queue for state funding for implementation.

The purpose of this stormwater master plan was to identify a comprehensive system of low-impact development treatment practices to address an increase in impervious surfaces and mitigate drainage issues to reduce the amount of sediment and nutrients from entering the Town’s waterbodies. CCRPC staff worked alongside Watershed Associates and Town officials to further the development of this stormwater master plan. The project was completed in April 2017
