Waterside — Weaver Pond Dredging Patton Park

HAMILTON, MA — T Ford Company, Inc. (TFCI) was contracted by the Town of Hamilton, Massachusetts to excavate approximately 5,500 cubic yards of sediments from a two acre frog pond located within the Town's widely used park system. Decades of organic deposition and a faulty outlet pipe had resulted in forming an extremely shallow pond which would flood the surrounding park areas following significant precipitation events making them unusable. To limit both the amount of park green space area affected and the amount of water handling required by the originally proposed material staging and dewatering area, TFCI proposed the installation of a Portadam® temporary cofferdam system to cut the pond in half and allow work to be performed in the dry on each side of the pond.

TFCI constructed a material load out area and utilized a series of excavators and timber swamp mats to pile the material near the load out area to allow the sediments to drain as much as possible prior to load out. Upon completion of excavation of one side of the pond, TFCI removed the Portadam® structure and allowed the excavated area to flood. TFCI worked with the Town, local farms and material suppliers to distribute the excavated sediments and ensure future reuse of the richly organic soils.
