Dam Safety

The Massachusetts Department of Conservation and Recreation requires that all private and public dam owners register, inspect, and maintain dams in good operating condition. Regulation 302 CMR 10.07 states that dam owners must hire a qualified engineer to inspect and report results every 2 years for High Hazard Potential, every 5 years for Significant Hazard Potential, and every 10 years for Low Hazard Potential. GPR, Inc. is well experienced in providing the services for the preparation of Phase 1 Inspection Reports and will work with Clients to ensure that dam ownership responsibilities are understood and fulfilled.

Phase 1 Inspection and Report:

· Research history of dam, including design plans, historical operating records, and insurance (FIRM) flood studies

· Evaluate existing conditions at the site based on visual inspections and a review of available reports, investigations and data previously submitted by the owner

· Recommendations for immediate or remedial action

· Preparation of Operation & Maintenance Plans and Emergency Action Plans

Todd Pond Dam is small earthen dam owned by a private homeowner’s association. GPR provided a repair plan for the dam, which had been overtopped repeatedly in its history, and was showing signs of crest and downstream slope erosion. GPR designed the dam repair and permitted the work through the local Conservation Commission and the Department of Conservation and Recreation Office of Dam Safety.

The Plow Shop Pond Dam is a privately owned intermediate sized dam. The Massachusetts Department of Conservation and Recreation Office of Dam Safety deemed the dam a “Significant Hazard Potential”. GPR conducted a Phase 1 Investigation and is now assisting the owner with repair recommendations to satisfy the DCR requirements for further action.

Carding Mill Pond Dam is an Intermediate Size High Hazard Dam built by Henry Ford during his renovation of the Wayside Inn property nearby, and has been the subject of three dam inspections in recent years. GPR was retained by the Town of Sudbury to perform a Phase I Dam Safety Follow-Up Inspection and Report and to address recent maintenance done by the Town.
