Pare Corporation was retained by the Town of Hampton to design repairs to the 17-century Old Mill Pond Dam due to a variety of dam safety concerns including a partially failed spillway section, unstable downstream retaining walls, irregular embankment sections, and inadequate hydraulic discharge capacity. Given the historic and culturally sensitive nature of the site, particularly the downstream wall and adjacent Deacon Tuck Grist Mill, the decision was reached to replace the existing dam with a new structure located shortly upstream of the existing embankment.

Pare coordinated a subsurface exploration program to assess foundation conditions along the alignment of the anticipated dam structure. Alternatives recommended included either an earthen embankment section or a concrete dam. Upon selection of the earthen embankment by the Town, Pare designed a structure compliant with NHDES dam safety standards. Pare also coordinated the completion of archaeological site assessments to evaluate the impacts of the work upon the cultural resources at the site.

Upon completion of the design and preparation of construction documents, Pare provided bid-phase and construction-phase services.
