Scarborough River Maintenance Dredging

The proposed work consists of hydraulically dredging approximately 111,000 cubic yards (cy) of sandy material from the 8-foot entrance channel, 6-foot inner channel, and 6-foot anchorage (below Mean Lower Low Water) and placing the material on Western Beach. Sandy shoal material dredged from the project will be pumped approximately 6,000 ft to Western Beach which is just north of the 8-foot entrance channel in Scarborough, ME. Of the 111,000 cy project total approximately 76,000 cy is required dredging with the remaining 35,000 cy considered 1-foot of allowable overdepth to bring the project back to its authorized dimensions. The work in this area will require significant coordination around the tide as the Scarborough River sees tide ranges as high as 10+ feet during normal tide cycles. Dredging and disposal operations will be performed between November 1, 2023 and March 1, 2024 to meet environmental time of year (TOY) restrictions.
