Jericho: Bolger Hill Road Supplemental Study, May 2021

2.8 MB
Year:
2021
Theme:
Storm Water, Technical Assistance
Description:
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.

Town of Milton Stormwater Master Plan

1.2 MB
Year:
2019
Theme:
Storm Water, Stormwater
Description:
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.

Richmond Stormwater Master Plan

38.9 MB
Year:
2018
Theme:
Stormwater, Water Quality
Description:
Within this Plan, localized stormwater problems are examined at a larger scale (e.g., throughout the village core) to determine their relative contributions and aid in setting priorities for addressing challenges related to stormwater runoff. As adjoining municipalities also take increasingly comprehensive views of stormwater management issues and planning, these plans are one-stop resources that can improve coordination and increase opportunities for collaboration in meeting watershed-related needs across political boundaries.

Town of Underhill Stormwater Master Plan

12.3 MB
Year:
2018
Theme:
Storm Water, Stormwater
Description:
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.
