Stormwater for US 7, VT 2A, VT 127

Colchester, Vermont | Vermont Agency of Transportation

Stormwater design and permitting assistance was required for the widening and upgrade of approximately one mile of roadway near the intersections of Routes 7, 2A, and 127. The project entailed widening, overlay, and reconstruction, as well as new curbing, drainage, bike lanes, signals, and signage. D&K provided drainage design, hydrologic analysis of stormwater runoff rates and volumes, hydrologic analysis of future build-out, hydraulic analysis for pipe sizing, wetlands delineation, identification and conceptual design of stormwater treatment practices, and presentation of reports and alternatives.
