USDA Forest Service White Mountain National Forest Beaver Pond Dam Design-Build

North Woodstock, New Hampshire

Survey and base mapping services for a design-build project to rehabilitate the Beaver Pond Dam in the White Mountains of New Hampshire. The dam was in poor condition with a failing concrete spillway, seeping earth embankment, and an inoperable low-level outlet. The Forest Service required NHDES dam safety regulations be followed throughout design and construction. D&K developed design measures to minimize environmental impacts caused by construction activities, including mitigating sediment release.

The dam, surrounding embankments, and watersheds were surveyed utilizing GPS controls. Base plans were developed in state plane coordinates for design. All work was conducted in accordance with the US Forest Service Survey Standards & Specifications.
