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.

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.

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).

On behalf of Chittenden County Regional Planning Commission (CCRPC) and the City of Burlington (City), Stone Environmental, Inc. (Stone) has completed the Right of Way Condition Inventory for Stormwater Management within Burlington Wards 5 and 6. 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. These two maps can be accessed by viewing the embedded links in the paragraph titled 1. Introduction.

The CCRPC and the City of Burlington partnered to identify options to improve connectivity for low-stress bicycling, improved pedestrian crossings, and stormwater management in the southwest section of the Old North End – one of Burlington’s densest and most diverse neighborhoods. The final report includes conceptual designs and conceptual cost estimates for the preferred alternatives connecting Battery Park, the Old North End Neighborhood Greenway, the Depot Street Neighborhood Greenway, and the Lakeview Terrace Neighborhood Greenway.

Lake Street in Burlington is a shared use street that connects the City core to the northern waterfront. There are two mid-block pedestrian crossings on this segment. The road is landscaped with street trees and granite blocks. Stormwater runoff sheet flows across the road from east to west. Runoff from nearby properties drains over Lake Street at the driveway intersections. Most of the stormwater sheet flows into small swales or ponds in the nearest low spot. The City with funding from the CCRPC studied possible pedestrian, streetscape and stormwater improvements for Lake Street in the project area.

In accordance with the agreement between the Town of Jericho, the Chittenden County Regional Planning Commission (CCRPC), and Hoyle, Tanner & Associates, Inc., this Scoping Study - Technical Memo (Study) has been prepared to investigate four (4) alternatives for roadway drainage and erosion solutions for Bolger Hill Road within the existing roadway ROW and Town parcels. As this is a technical study, no public meeting was held, however the following general purpose and need statements has been developed based on our meeting with Town and CCRPC Staff. Purpose: The purpose for this Study is to provide roadway and drainage alternatives to reduce the 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.

This project developed Final Design Plans and a Cost Estimate for road and drainage improvements for Beebe Lane located within lands managed by the Lake Iroquois Recreation District within the Town of Williston.

In 2018 the Chittenden County Regional Planning Commission (CCRPC) received grant funding from the Vermont Agency of Natural Resources (VTANR) Clean Water Initiative Program to supplement funds from the Town of Milton to develop a Stormwater Master Plan (SWMP) for Milton. Fitzgerald Environmental Associates, LLC (FEA) was hired by the Town and CCRPC in the summer of 2018 to develop the plan. This final SWMP report for the Town of Milton represents significant efforts and collaborations over the last year between the Town, FEA, CCRPC, VTANR, and other partners, including private landowners and business owners, interested in mitigating stormwater and improving water quality. The goal of this project was to identify and prioritize stormwater improvement projects throughout the Town, with a focus on Town owned properties. Project prioritization followed the Unified Scoring Metrics recently developed by VTDEC (2018a). Conceptual design plans (30% design) were prepared for 15 high-priority projects. Additional phosphorus loading and removal estimates were completed to assist the Town with planning for future efforts to prepare the Phosporus Control Plan.
