Abstract: | The Maurice River Federal channel maintenance dredging will clear shoals to maintain safe navigable depths to 7 feet MLLW plus 2 feet overdepth in areas determined by the project manager in coordination with local maritime users. The dredged material placement location has been developed in coordination with natural resource regulatory agencies and other local project stakeholders. Placement operations of the dredged material is a beneficial use (BU) for the purpose of raising elevations incrementally within the flooded marsh system consisting of expansive subtidal areas, intertidal mudflats and saltmarsh vegetation. Saltmarshes are protective features that provide natural infrastructure protection to the dike and important habitat within the state’s WMA. Periodic maintenance dredging is needed in the lower portion of the Federal channel (between approximately Station 1+500 to Station 13+000) in to remove sediments for navigation safety for recreational and commercial users. Only the lowermost reach of the Federally-authorized channel south of Bivalve to the river mouth at the confluence of Delaware Bay requires the proposed maintenance dredging in 2023 (approximately 11,500 linear feet of channel). Authorized depths are 7 feet deep and 150 feet wide within this reach. The remainder of the Federal-authorized channel continues north with a 100-foot-wide channel of the same depth extending to the fixed bridge upriver at Millville, a total distance of about 24 miles (Figure 15). Only the lower section that is proposed for maintenance dredging is less than the authorized depth of 7 feet (MLLW) |
