GEOTECHNICAL CONSIDERATIONS

SUMMARY OF AVAILABLE SUBSURFACE DATA

ATLANTIC OCEAN CHANNEL PHASE 2

In general, there is a combination of sand, silt, coarse-grained material, and fine-grained material between ST 1730+00 to ST 1880+00 and ST 1978+00 to ST 2215+74 as indicated in the Geotechnical Summary Report within the Specifications.

SUMMARY OF AVAILABLE SUBSURFACE DATA

ATLANTIC OCEAN CHANNEL PHASE 2

Norfolk Harbor and Channels Navigation Improvement Project General Reevaluation Report (2018)

• Summarized and evaluated geotechnical information for the entire Norfolk Harbor Improvements project.

• Subsurface data obtained between 1981 and 2009

• Exploration methods: Vibracores, Gravity cores, Grab samples, Boreholes, and Cone

Penetration Test (CPT) probes.

• Material encountered in Atlantic Ocean Channel Phase 2 may consists of sands, silts, clays, coarse-grained material, and fine-grained material.

PROJECT CONSTRAINTS

Craney Island

• Intent is to capture sandy material in a confined location for immediate use through separate earthwork contract.

• Optional beneficial use placement location of sandy dredged material from AOC Phase 2.

• Fine grain material not suitable for placement at CIDMMA may be directed for placement within the Damneck Ocean Disposal Site

(DNODS).

• Maximum daily production rate in a 24-hour period per cell is 22,500 CY.

Craney Island

• It is intended that the sub-containment cell within the CIDDMA northeastern cell is constructed concurrent to keep pace with AOC Phase 2 dredging and placement operations.

• There is a secondary sub-containment cell with the CIDMMA northeastern and center eastern cells. The secondary sub-containment cell shall be constructed under the AOC Phase 2 Contract.

• Other Contractors will be working in previously filled sub-cells concurrent with ongoing dredging and placement operations.

• Placement of dredged material will generally occur from the southern limit of the sub-containment cell advancing to the North then West.

Miscellaneous Constraints

• Mechanical Dredging

• Material Placement in Craney Island Rehandling Basin (CIRB) will not be allowed.

• Cell Rotation Requirements at CIDMMA

• Not to exceed 22,500 CY of placed material in a 24-hour period per cell.

• Government’s intent to limit the use of facility to one cell at a time.

• Most placement at the CIDMMA will be confined to the primary placement area in the North Cell.

• Some placement at the CIDMMA will be confined to the secondary placement area in the Center and North cells.

• Minimal freeboard currently available .

ENVIRONMENTAL CONSIDERATIONS

WATER QUALITY MONITORING

• Comply with requirements for Section 404 of the Clean

Water Act for discharges associated with confined disposal facilities.

• Manage spillboxes to ensure adequate ponding depth for effective sedimentation & to maximize use of the available effective weir length ensuring that only the clarified supernatant flows over the weir crest.

• The Contractor must maintain a daily average Total Suspended Solids (TSS) concentration of less than 500 mg/l. The "less than" 500 mg/l TSS concentration is a threshold limit and is not a TSS target or goal.

WATER QUALITY MONITORING

• Environmental Testing and Upland Effluent

• TSS samples

• Collect every 12 hours at the weir crest of each operating spillbox.

• Hach 900 Colorimeter model #48450-00, program 94

"Suspended Solids", or approved equal.

• 1000 ml wide mouth polyethylene bottle (Nalgene 2104-0032 or equal).

• Log digitally in Water Quality Database.

• Visual inspection for clarified water required every 4 hours at each operating spillbox.

• Spillboxes shall be maintained and weir boards adjusted so that only clarified water is released.

PROTECTED SPECIES

• Native habitat for eagles, hawks, egrets, herons, pelicans, terns, plovers, dolphins, manatees, whales, sturgeon, & other wildlife protected by federal law or species of special concern for Virginia agencies.

• Nesting birds may cause delays if found in placement/work area.

• May 15 – August 30: Least Tern and Black Necked Stilt nesting season

• January – May: 1st Bald Eagle Nest in 2020

• The Contractor shall monitor the pond area in the active containment cell to ensure pond backwaters do not flood nesting areas.

ENDANGERED SPECIES MONITORING-

MECHANICAL DREDGES

• Endangered Species Training provided by USACE.

• Designate a look out to monitor visible action area from dredge plant:

• Look for parts/pieces of Atlantic sturgeon entrained in the cutterhead, floating around the dredge or collected in the inflow inside the upland placement area.

• Document observations & notify COR ASAP.

• Follow “Sturgeon Incidental Take Procedures.”

• Fin clips

• Measurements, photos, specimen preservation

ENDANGERED SPECIES MONITORING-HOPPER

DREDGES

• Two Protected Species Observers (PSO) are required.

• Operate dredge per the specifications to minimize takes.

• PSOs must inspect draghead, Turtle Excluder Device

(TED), & UXO after each load.

• No openings larger than 4 inches x 4 inches on

TED or draghead.

• Follow “Sea Turtle Incidental Take Procedures” & 2018

Biological Opinion RPMs.

• Measurements, photos, specimen preservation

(keep remains cold on ice, not in water).

• Transfer of remains or live turtles to VAQS.

ENDANGERED SPECIES MONITORING-OPTIONAL

BEACH RENOURISHMENT (CROATAN/RESORT)

• Protected Species Observers (PSO) are required to inspect the beach for turtle nesting activity every 2 hours, 24 hours/day from May 1 through Nov 15.

• All placement activities will be halted within a 500 ft buffer if activity is discovered.

• Nests within construction zone will be relocated by qualified entity. A predetermined relocation fee will be charged. Contractor must pay the relocation fee. USACE will reimburse the Contractor for the fee.

• VAQS conducts early morning crawl surveys during nesting season and must be provided unimpeded and safe access.

• New required environmental training for all beach construction crew members conducted by USACE Biologist.

ENVIRONMENTAL PROTECTION PLAN (E.P.P.)

• Contractor must submit E.P.P. that includes:

• Spill Control Plan

• Hazardous Waste Controls

• Non-Hazardous Solid Waste Disposal

Plan

• Recycling & Solid Waste Disposal Plan

• Contaminant Prevention Plan

• Historical, Archaeological, Cultural, Biological, & Wetland Resources Plan

• Endangered Species Plan

UXO/MEC SCREEN

• Unexploded ordinances have been documented in Atlantic Ocean Channel.

• Land-based UXO technician(s) are required at CIDMMA during placement.

• UXO/MEC screens are required on dragheads and at the CIDMMA.

• Screens on the dredge shall be no larger than 1.25 inches x 6 inches.

• Discharge end screens shall retain all items 0.75 inches in diameter.

• Modifications to the required size of the UXO/MEC screen will only be considered for use between December 1 and March 31.

CONTRACTING REQUIREMENTS

ACQUISITION STRATEGY

• Dredging contract will most likely be full and open sealed bid.

• Sources Sought issued 14 November 2022.

• Magnitude $25 - $100 M anticipated.
