Below is a list of projects that the Town is currently working on to meet permit requirements under the State MS4 permit.
Flow Restoration Plans
Under the Flow Restoration Plan for Indian Brook, the Town is responsible for implementing the following projects:
- Sydney Drive Detention Pond Retrofit
- This project is located in a wooded area on a Town-owned parcel that is adjacent to Sydney Drive in Lang Farm. The detention pond will be retrofitted into an underground storage and infiltration chamber that will manage 14.9% of the high flow reduction target. The Town worked with Dubois & King for the design and the University of New Hampshire’s Stormwater Center. A sand layer with 10% drinking water treatment residuals from Champlain Water District will be placed under the chambers in order to achieve phosphorus removal with the system. The Town received a grant from the Vermont Agency of Transportation in the amount of $304,942 for engineering services and construction. Construction is expected to take place in 2020.
- LDS Church Detention Ponds Retrofit
- This project is located on the LDS Church property on Essex Way. There are two detention ponds on the property - North System and South System. The North System will be retrofitted into an underground storage chamber and the South System will be retrofitted into an underground sand filter in order to receive additional phosphorus removal. Stormwater infrastructure will be modified to take in additional stormwater from Essex Way, Lang Farm, and the Essex Resort & Spa. This project will manage 46.2% of the high flow reduction target. The Town received a grant from the Vermont Agency of Transportation in the amount of $1,346,275 for engineering services and construction and is currently working with VHB to complete the project. Construction is expected to take place in 2022.
Phosphorus Control Plans
Under the newly issued MS4 permit, the Town is required to develop a Phosphorus Control Plan which identifies projects that need to implemented in order to reduce the amount of phosphorus entering the Lake by approximately 20% from municipally-owned and operated developed lands. The following projects will help the Town with meeting these requirements.
- Phosphorus Control Plans
- The Village secured a grant from the Vermont Agency of Transportation in the amount of $50,000 to develop a Phosphorus Control Plan in collaboration with the Town. Because watersheds know no boundaries, the Town and Village are working together to strategically implement projects in order to meet the requirements in a cost effective manner. Stone Environmental and Milone & MacBroom were hired and the Plan is currently in progress. A final draft is due to the State on April 1, 2021.
- Cul-de-sac Retrofit
- The Town and Village secured a grant through the Vermont Agency of Transportation in the amount of $338,924 to retrofit three oversized cul-de-sacs by removing the pavement in the center and installing bio-infiltration systems. The cul-de-sacs are Oakwood Lane, Sage Circle, and Acorn Circle. Stantec and Stone Environmental were retained to complete the work. This is a pilot project to determine whether this will be an innovative and cost effective solution for removing phosphorus as there are over 30 cul-de-sacs in the Town. A water quality monitoring program will be in effect following the construction of the systems. Construction is expected to take place in 2021 or 2022.
- Tanglewood Scoping Study
- The Town received a grant through the Chittenden County Regional Planning Commission’s Unified Plan Work Program in the amount of $39,000 to conduct a scoping study on Tanglewood Drive to improve pedestrian facilities and to mitigate the impact of stormwater at the end of Fern Hollow as there is severe erosion in the gully. Stantec was retained for the work. A resident survey was sent out in mail in December 2019 asking for input on various design options. Conceptual plans will be completed in 2020.
- Gravel Road Improvements on Hanley Lane and West Sleepy Hollow Road
- The Town secured a grant in the amount of $38,696 through the Grants-in-Aid Program administered by the Department of Environmental Conservation and Chittenden County Regional Planning Commission to bring road segments on Hanley Lane and West Sleepy Hollow Road up to current state standards. The work will be contracted out and is expected to take place in 2020.
Closed Circuit Televising
Because there has been an emphasis on improving the water quality of local streams and Lake Champlain, one component of the Town’s stormwater program that has been neglected is the status of aging infrastructure. Many of the pipes in the Town are corrugated metal pipes that are 40 to 60 years old. The Town secured a grant from the Chittenden County Regional Planning Commission’s Unified Plan Work Program in the amount of $45,000 to use a camera to televise stormwater pipes and to develop an infrastructure replacement plan. This project will be a multi-year project and will start with Painesville, Forestdale, and Sand Hill Road. The goal of the project is to televise all the stormwater pipes in the Town and develop a long-term maintenance and replacement plan to use for planning purposes. The project is currently underway and televising will begin in 2020.
