RT Group, Inc. (RTG) was retained by Hugo Key & Sons, (HK&S) Inc. to develop the dewatering, flow diversion, and temporary support of excavation plans for the reconstruction of Featherbed Lane Dam in North Kingstown, Rhode Island.

The project consisted of replacing the existing stone arch spillway and fish ladder outlet with new precast concrete box culverts and reconstructing the existing municipal roadway along the crest of the dam.

The Plan included analyzing the existing hydraulic capacity of the dam; designing a temporary braced cofferdam; preparing the dewatering plan; sizing riprap needed to protect the cofferdam during storm events; and designing a flow diversion system using overland pumping methods.
