VTrans Barney Brook Wetland Mitigation Site

 

Bennington, Vermont

In order to mitigate for the wetland impacts associated with the construction of the Bennington Bypass project, DuBois & King assisted the Vermont Agency of Transportation in the identification, selection, and design of a 28 ± acre wetland mitigation complex along Barney Brook in Bennington. The plan entailed the conversion of 6.7 acres of upland to wetland, the enhancement of 5.5 acres of existing wetland, and .9 acres of riparian corridor enhancement.

A hydrologic and hydraulic evaluation was conducted to forecast the altered groundwater and surface water conditions necessary to support wetland hydrology/plantings. The analysis included installation and monitoring of observation wells and the modeling of existing and projected groundwater levels using the “Boss International, Groundwater Modeling System” software. Both the US Army Corps of Engineers and the Vermont Agency of Natural Resources approved the wetland complex design.

D&K assisted VTrans with construction services as a resident inspector and provided services during the five-year monitoring period. Construction phase services included project stakeout, quantity calculations, review of plantings, preparation of bi-weekly payment amounts, daily reports, and recording as-built information.
