Pursuant to Executive Order 11988 (Floodplain Management) and Federal Emergency Management Agency’s (FEMA) implementing regulations at Title 44 of the Code of Federal Regulations Part 9, FEMA hereby provides final notice of its decision to provide Public Assistance floodplain. Funding would be provided through Vermont Emergency Management to the Town of Cabot to Mack Mountain Road culvert.
The action is located on Mack Mountain Road in Cabot, VT. The project is to demolish and re-construct a 20 FT wide x 65 FT long box culvert by erecting 70 (Cubic Yards) CY of concrete footing and wingwalls, installing 242 CY of subbase, 214.99 (Square Yards) SY of binder, and 214.99 SY of surface. The portion of asphalt road (19ft. wide x 32ft. long) directly above the culvert will consist of installation of 348 (Linear Feet) LF of thermoplastic lines and 300 LF of guard rail. The proposed action incorporates mitigation, which will increase the resiliency of the structure making it less prone to repetitive damages.
The project is within a mapped special flood hazard area (1% annual chance floodplain). The proposed action will restore natural floodplain values by widening the stream passage beneath the road to a natural bank full width. This will allow the stream to flow at a more natural volume and lessen the likelihood of the road overtopping or washing out in future flood events. A map of the area of available upon request.
The project must in be in a floodplain because the existing culvert is part of a roadway system that is in the floodplain. The applicant may have considered replacement in-kind, but the new structure will have substantial improvement to withstand floodwater in the 1% annual chance floodplain. Grant conditions will also require compliance with all federal, state and local laws, including coordination with the local floodplain administrator.
Map requests and comments about this project and potential floodplain impacts should be submitted within 15 days of the date of this publication to:
