Pomainville Dam Removal

Shoreham, Vermont

D&K provided evaluation, survey, and preparation of permit applications for an earthen dam. Vermont Agency of Natural Resources (VANR) personnel determined that the dam’s original 30-inch diameter metal spillway riser had been replaced with a 24-inch plastic pipe and the emergency spillway had been filled to the crest elevation of the dam. Presented three potential remedy options to bring the dam back into compliance with VANR dam safety regulations. The determination was made to remove the dam. D&K was responsible to provide hydrologic analysis of the watershed using HydroCAD, and prepare conceptual and final designs for removal of the dam and restoration of the stream. D&K completed the dam safety permit and coordinated with Vermont State wetlands and dam safety officials. D&K provided construction observation services.
