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.

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.

Hoyle, Tanner & Associates, Inc. completed stormwater structure and pipe condition assessments and recorded collected data in Town GIS format for future integration with the Town’s Asset Management Program. The overall stormwater infrastructure refurbishment need was identified and a Capital Budget Program for Stormwater Infrastructure was developed for future refinement by Town Staff to aid in future infrastructure planning efforts. Results of a Top Down pipe condition analysis - completed based on pipe material, typical service life and estimated installation year - broadly estimates $5.1M in stormwater infrastructure capital budget need. However, the results of the pipe segment Zoom Camera condition assessments indicate that approximately 75% of this $5.1M in stormwater infrastructure capital budget need had a “Pass” rating. This reveals that a significant amount of the stormwater infrastructure, although exceeding a typical service life, has some service life remaining. There were also Stormwater Pipe Segments that had an Emergency Rating indicating immediate work required. Many of these pipes were not in the $5.1M dollar Top Down evaluation.

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.

The ultimate objective of this stormwater master planning project is to support the Town in improving stormwater management, by providing a list of high priority water resource concerns and conceptual solutions that support the development and implementation of future restoration projects in an efficient and targeted manner. This Stormwater Master Plan first incorporates information from existing plans and datasets to create a single, town-specific resource to guide future stormwater management activities. The resulting stormwater management planning information and resources are included in Section 2 of this report. This Stormwater Master Plan also:  Provides a means for comparing anticipated benefits of individual stormwater improvement projects;  Provides recommendations to address stormwater problems, including a prioritized list of problem areas that can assist the Town in directing resources to high priority projects; and  Presents conceptual solutions for stormwater management measures in select high priority problem areas.

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.

This scoping study identifies and evaluates alternatives that address stormwater management, bicycle and pedestrian accommodations along West Lakeshore Drive, and improvements at the Blakely Road and Lakeshore Drive intersection

This scoping study identifies and evaluates alternatives that address stormwater management, bicycle and pedestrian accommodations along West Lakeshore Drive, and improvements at the Blakely Road and Lakeshore Drive intersection.

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
