This project focused on inspection of existing storm drainage infrastructure and development of an asset management database of the assessed system.  Data and information generated by this effort could be used to create a stormwater infrastructure replacement plan.  Phase I was completed in FY21, Phase II in FY23,and Phase III in FY23.  Phase IV began in FY25 and was completed in FY26.  The findings will be used to schedule implementation of pipe repairs, lining, or replacement.

Appendix files for the VT 116 Patrick Brook Culvert Assessment Study.

This study analyzed the existing condition of three culverts in Hinesburg; 1) the Patrick Brook Culvert condition across VT 116, located 500 ft north of Commerce Street, 2) a culvert across VT 116 located just north of Buck Hill Road and 3) a culvert located under Buck Hill Road.  Assessments were conducted to determine the bank full width and ordinary high-water-mark of Patrick Brook and other drainage above and below the culvert. This project developed 10% level conceptual plan and cost estimate for each culvert location and provided basic verification of engineering feasibility and structure size based on the Hydraulic and Hydrology (H&H) analysis.

The Shelburne MS4 Stormwater Master Plan Appendices are available here.

The Town of Shelburne in collaboration with CCRPC developed a MS4 Stormwater Master Plan (SWMP) that would guide the Town's stormwater capital improvements over the next 14 years to meet the MS4 permit requirements by 2036.  This SWMP focused on the phosphorous and flow reduction requirements as estimated today.  Key findings from the Phosphorous Control Plan (PCP) developed in 2020 were presented throughout this SWMP to provide context for the remaining work required to meet the PCP target.  This study re-evaluated the Flow Restoration Plan (FRP) developed in 2017 to assess the feasibility of certain proposed practices, and to relate the total proposed flow reduction volume to updated estimates.

The study evaluated stormwater drainage concerns within the Town Common area of Westford and existing storm drain under VT Route 128 that drains stormwater from the Village Common area to the Browns River.  The area at the existing outlet pipe is eroded and requires relocation due to a redevelopment project on the 1705 Rte 128 property.  This study developed conceptual plans for relocation of the storm drain under Route 128 and possible outlet treatments and stormwater best management practices for improving drainage in the Village Common area.

On behalf of Chittenden County Regional Planning Commission (CCRPC) and the City of Burlington (City), Stone Environmental, Inc. (Stone) completed in June 2022 a Right of Way Condition Inventory for Stormwater Management within Burlington Wards 2 and 3. A summary of the inventory and tasks completed are described below. Data from the project is in two web maps Soil Boring Status Map and BTV Soil and Utility ROW Assessment Map. See section 1. Introduction to click on embedded web links to these maps.

Tanglewood Drive, between Cindy Lane and Woodlawn Drive, is a relatively low-volume car-oriented street in the Town of Essex with no accommodations for bicycles and pedestrians. There is also recurring problems with the outlet to the closed drainage system that has resulted in significant erosion near the outlet adjacent to Fern Hollow Road. This study developed alternatives to address the stormwater issues and offer improvements for walking and biking. A preferred alternative was approved by the Essex Selectboard in September 2021.

In accordance with the agreement between the Town of Jericho, the Chittenden County Regional Planning Commission (CCRPC), and Hoyle, Tanner & Associates, Inc. (Hoyle, Tanner), this Final Design Report has been prepared to synthesize previous deliverables and to provide 100% Design Plans for development of two stormwater Best Management Practices (BMPs) within the Town Green located in Jericho Center. Preparation of this report was funded through a Design Implementation Block grant from the Vermont DEC Clean Water Initiative Program administered by the Mount Ascutney Regional Commission and through funds from the Town of Jericho. The following general purpose and need statements has been developed based on our initial meeting with Town and CCRPC Staff in 2019. Purpose The purpose for this project is to provide stormwater treatment for the Bolger Hill Road area and aid in the reduction of erosion that is currently occurring along Bolger Hill Road and to reduce the sediment accumulation at its intersection with Jericho Center Circle. Need The need for the project is to reduce the gravel, which comes from Bolger Hill Road, that gets washed into the Town Green and abutters properties after large storm events. The Town would like to improve the water quality in this area through the construction of Best Management Practices (BMPs) within this project. Goals The Goal of the project is to develop 100% Design Plans and Engineer’s Estimate of Probable Construction Costs for delivery to the Town and CCRPC. A Drainage study was completed by Hoyle, Tanner in January 2020 and was titled Drainage Alternatives Study, Bolger Hill Road Drainage Improvement Project, Jericho, Vermont (see link in Appendix A).

The scope of the Bolger Hill Drainage Scoping project was to provide engineering services for the advancement to conceptual design (25%) of the Alternative #4 Design presented in the January 2020 Bolger Hill Road Drainage Alternatives Study. This project builds on that previous study that investigated drainage issues and evaluated improvement options for Bolger Hill Road in Jericho. A survey was conducted, and conceptual plans were drafted to more accurately develop a cost estimate for improvements to Bolger Hill Road. Further design aspects of the Bolger Hill Drainage Scoping project conceptual design are noted below. The Jericho Center Circle SW BMP Design project is not discussed further in this Design Narrative. The purpose of the project is to provide a roadway and drainage alternative that reduces the erosion that is currently occurring along Bolger Hill Road and to reduce the sediment accumulation at its intersection with Jericho Center Circle. The need for the project is to reduce the gravel, which comes from Bolger Hill Road, that gets washed into the Town Green and abutters properties after large storm events. The Town would also like to improve the water quality in this area.
