MONTPELIER, VT — VHB was awarded three of the 10 awards given at the 2021 American Council of Engineering Companies of Vermont’s (ACEC/VT’s) Engineering Excellence Awards Celebration. The annual awards honor engineering projects that demonstrate exceptional innovation, complexity, achievement, and value. Of the projects submitted, VHB was recognized with Merit Awards for the Williston I-89 Stormwater Retrofits Project and the Killington Road Master Plan and received the Grand Award in partnership with Golder Associates for the Duxbury Crossett Hill Road Project.The Vermont Agency of Transportation (VTrans) engaged VHB to implement their first interstate stormwater retrofit project, which included new stormwater treatment practices to address the Allen Brook watershed stormwater impairment along the I-89 median in Williston, Vermont. VHB developed design plans to meet the high-flow reduction targets and maximize phosphorus reduction in accordance with the Allen Brook Flow Restoration Plan.VHB worked with the Town of Killington in crafting a plan to guide the continued development along the nearly four-mile Killington Road corridor serving the Killington ski resort. The plan will assist the town in securing grant funding to transform the roadway into a modern, multimodal facility, which will include the integration of bus stops, turn lanes, streetscape enhancements, and sidewalks.The Town of Duxbury sought the expertise of VHB, who worked in collaboration with Golder to design a new roadway embankment, including the layout of stone fill slopes, ditches, and guardrails, as well as a temporary construction access road. With geotechnical guidance from Golder, VHB conducted natural and cultural resource reviews, calculated permanent and temporary impacts, and prepared all necessary application materials. The embankment design protects Crossett Brook and Crossett Hill Road from a recurring landslide, stabilizing the roadway slope and streambank.
