2 Goodbye Jeff Richter!!

3 Navigation/Operations

4 USACE Goal/Mission: To maintain safe Navigation in Federal Channels using methods that are most (1) economically feasible (2) engineeringly sound and (3) environmentally responsible. (It comes last but at least it s mentioned, right??)

15 BUILDING STRONG

16 Eagle Island Raising dikes to 42 EA study to raise dikes to 50 with toe berm 20-year DMMP to construct Cells 4 & 5??

17 FY 16 Dredge Projects to be awarded by the 4 th Quarter: Morehead City Harbor Inner Harbor Contract Wilmington Harbor Anchorage Basin Contract Wilmington Harbor Mid-River Contract AIWW High Use Maintenance Dredging

18 Environmental Windows Windows for bird nesting locations: a) Oceanfront beach placement: November 16 March 31 If disposal is expected to extend past March 31 on certain beaches, coordination by about March 15 with Environmental Resources Section is necessary. Decision may be that work can continue past March 31 if survey reveals that no nesting birds will be disturbed along pipeline alignment. Following completion, if survey reveals nesting birds along pipeline alignment, pipe or other equipment may have to stay in place until nesting is completed.

19 Environmental Windows Windows for bird nesting locations: b) Diked upland disposal islands: September 1 March 31 Although not a formally required window, disposal areas need to be checked for bird nesting. If a nest is found, we will coordinate with appropriate resource agencies. We may allow Contractor to continue work while avoiding the nest. If bird nesting is not an issue, there is no window.

20 Environmental Windows Windows for bird nesting locations: c) Control-of-Effluent Islands: September 1 March 31 Parnell and Wells (Old House and Rollinson Channels dredging project), Pelican and South Ferry Slip (Wilmington Harbor/CFR dredging project), Wainwright Island (Wainwright Slough dredging project), Islands D, G, F, et al, (Manteo Shallowbag Bay dredging project), Big Foot Slough Island (Big Foot Slough/Silver Lake Harbor dredging project).

21 Environmental Windows Windows for bird nesting locations: d) Maintenance of Upland Disposal Areas: September 1 March 31 If work begins prior to March 31, Contractor may continue into April provided no nesting birds are present. Presence of nesting birds stops project until all necessary coordination with resource agencies has been completed.

22 Coordination: Coordinate with NCWRC/USFWS to determine best pipeline route Attempt to coordinate scheduling of pipeline inspection Schedule an end-of project inspection after pipe has been demobilized.

23 Beneficial Use of Dredge Material

24 Bird Islands on the Cape Fear River

25 Assumptions: Horseshoe Shoal and Snows Marsh channels will be dredged every even year (2016, 2018, 2020, etc.) Quantity = about 135,000 cubic yards per cycle Bird islands will require replenishment in 2016, 2020, 2024 and again All material from Horseshoe Shoal and Snows Marsh channels will be of suitable quality for beach renourishment at Kure Beach and on Bird Islands.

26 Working with NOAA to start Thin Layer Disposal Program Method of restoring coastal marsh along Federal channels Camp LeJeune pilot project Combat erosion and sea level rise New concept to this District EA/Resource Agencies feedback Research/design Use of Govt Dredge, Snell

27 Navigation is Seeking Opportunities! Provide navigation solutions within the coastal region of NC: USMC Camp LeJeune, MOTSU USCG Stations Local Governments Along the NC coast, as needed Assist with planning, designing, and permitting docks, piers, breakwaters, etc. as needed: NPS (National Seashores) USFWS (Wildlife Refuges NCDPR (State Parks) NCWRC (Wildlife Boat ramps)
