PROJECT AUTHORITY AND PURPOSE

Project Purpose:

Principal purpose is ecosystem restoration to construct hard reef (31 acres), wetland (38 acres), and submerged aquatic vegetation (SAV) (94 acres) habitats.

Non-Federal Sponsor:

The City of Virginia Beach

Fully Funded project in 2018:

$39,000,000 (65% Federal, 35% Non-Federal)

Project Authority:

Resolution of the Committee of Transportation and Infrastructure of the U.S. House of Representatives, Docket 2558 & 704(b) WRDA, Ecosystem Restoration Authorization. Construction of the project was authorized by Section 7002 of the Water Resources Reform and Development Act of 2014.

Navigation/Recreation Considerations:

50-100 feet from oyster leases 341+ feet from private docks 3,662 feet from Federal Channel (western edge of reef) 6,099 feet from Federal Channel (southeastern edge) 2,264 feet from Long Creek Channel (center of reef) Reef is subtidal, low profile, MAX height of 12 inches (permit condition) No navigational markers necessary Post construction At least 6 ft clearance above reef at MLLW

No placement of material between May 31-September 30

PHASE 2 REEF PROJECT DESIGNS

50 FT

100 FT

Reef Design:

50-foot stripes of substrate 100-foot spacing in-between stripes MAXIMUM height of

12 inches off the river bottom

6 inches crushed VDOT #1 stone

6 inches clean, sorted fossil oyster shell

PHASE 2 REEF FOSSIL SHELL LOCATION

PHASE 2 REEF LAYDOWN AREA

PHASE 2 REEF PROJECT DEPLOYMENT

All reef substrate will be placed by mechanical clamshell from a barge Material will be recorded by GPS system to ensure proper placement.

No placement of material between May 31-September 30

PHASE 2 REEF SURVEY REQUIREMENTS

Three bathymetric surveys are required for this project.

1. Preconstruction survey to confirm depths have not changes since USACE survey

January 2022 and City of VB survey June 2023

2. After placement of 6 inches of crushed stone, a survey is requested to ensure the height of the substrate is within the tolerance.

3. As-built survey is requested post construction to ensure the entire reef height does not exceed 12 inches.

This survey has to be submitted to VMRC within 30 days of construction completion.

PHASE 2 REEF CRANEY ISLAND CONSIDERATIONS

All contractors must enter Craney Island through contractors' entrance

A key card for entry will be given upon contract award

PHASE 2 REEF FOSSIL SHELL

Project Need: 5,958 cubic yards of shell

2.2 Fossil Shell

Fossil shell needs to be screened and sorted to be free of debris including trash, vegetation, or other non-shell material prior to placement at the project site. Screening process can occur on Craney Island, or another location identified by the contractor, prior to the shells being transported to the Lynnhaven River. If the contractor uses Craney Island as the sorting location, the contractor is responsible for ensuring any debris from the sorting is removed offsite and follows any additional procedures noted in Policy WRD-01 attached as an appendix to the specifications.

PHASE 2 REEF SPECIAL ENVIRONMENTAL PERMIT CONDITIONS

(18) The permittee and the contractor are required to contact VMRC staff for a pre-construction meeting prior to the commencement of work that shall include an inspection of the staked reef striation corners and the proposed reef materials.

(19) The permittee shall provide a post-construction bathymetric survey of the reef area within thirty (30) days of the completion of work. The survey shall be referenced to mean low water and shall include depth measurements exterior to the limits of the reef limits. Any area with reef material placed at an elevation that exceeds 1-foot above the ambient substrate grade will be considered a violation of the permit.

PHASE 2 REEF SUMMARY

1. Construction timeline must consider no placement of material in Broad Bay between May 31- September 30

2. Three bathymetric surveys are required for this project

3. Reef height cannot exceed 12 inches

4. All material must be clean and free of debris or other material except what it is intended to be

5. Craney Island must be restored to pre-construction conditions

6. Anticipated solicitation end of 2023
