Neighboring towns include Randolph, Chelsea, Strafford, Royalton, and Bethel. The town’s highest peak, at 2,120 feet, is Brocklebank Hill near Chelsea. Other high points include Old Hurricane Hill (1,920 feet) at the northern end of the ridge running along the town’s western border, and East Hill (1,544 feet) just east of Tunbridge Village. The First Branch drops 200 feet as it flows south through town, from an elevation of 700 feet at the northern border, to a low of 500 feet where it crosses the southern town line. Vermont Route 110 (VT 110) following the river is the main route in and out of town. Strafford Road, running over the eastern ridge, is the other major road in town.

  • Benefit-Cost Analysis Report DRAFT
    December 4, 2020 To: Gianna Petito, District Manager, Winooski Natural Resources Conservation District From: Meghan Arpino, Gabe Bolin, PE, Stone MEMO Environmental, Inc. Stone Project No. 20-007 Subject: Hands Mill Dam Removal – BCA Analysis Memo Stone Environmental, Inc. (Stone) has completed a Benefit-Cost Analysis (BCA) as part of the Hands Mill Dam Removal 30% design effort. This memo provides a summary of the analysis, along with a BCA report and supporting documentation, that can be used as part of a larger grant application submission by the Winooski Natural Resources Conservation District (District) to the US Federal Emergency Management Agency (FEMA) for funding to support future project phases. The BCA is a method developed by FEMA that compares risk reduction benefits of a hazard mitigation project to its costs. The result is a Benefit-Cost Ratio (BCR), where a project is considered cost-effective when the BCR is at or greater than 1.0. To establish cost-effectiveness of a project, those that are applying to FEMA for project funding are required to use FEMA methodologies and tools. Stone used the FEMA BCA Toolkit, Version 6.0 (https://www.fema.gov/grants/guidance-tools/benefit-cost-analysis) for this analysis. The following sections provide an explanation of details and assumptions of the analysis. Relevant supporting documents are provided as attachments to this memo. 1. Analysis Methodology and Assumptions The overall analysis includes two mitigation actions, 1) mitigation at the dam property itself, including dam removal and 2) mitigation of impacts to the residential property at 16 Woodchuck Hollow Road, which is located at the intersection of West Corinth Road and Woodchuck Hollow Road, immediately adjacent to the dam property.
