DESCRIPTION: The Old Morris Canal Dam consists of a granite block spillway across the Rockaway River that is flanked by concrete and stone training walls. The project consisted of a hydrologic and hydraulic analysis of the dam’s drainage basin and an assessment of the existing dam structure. SCE then designed grouted riprap overtopping protection for the shoreline above the spillway training walls to provide erosion protection for the 100 year storm event. Additionally, repairs to the stone and concrete training walls and riprap slope protection for the downstream channel were designed by SCE.
The proposed grouted riprap protection area encompassed approximately 3,000 square feet with an estimated 150 tons of riprap. A cofferdam system will be utilized during construction to access the areas of work. Existing access to the dam site is via a walking trail along the Morris Canal, south of Main Street in the Town of Boonton. This access will be closed to the public during construction and temporarily utilized for project access and materials/equipment staging.
Required permit applications prepared by SCE for this project included a NJDEP Dam Safety Permit, a NJDEP Freshwater Wetlands General Permit 18, and a Soil Erosion and Sediment Control Permit from the Morris County Soil Conservation District. As part of our contract with the Town of Boonton, SCE performed construction administration activities for this project.
