DISCLAIMER

Today’s Goal: To obtain insight and feedback from industry for a future ecosystem restoration project at Belle Isle State Park.

Information gathering for anticipated construction using innovative, modern methods for construction in a high traffic public park.

Solicit input regarding challenges such as site access, staging areas, environmental constraints, etc.

Primary means and methods, challenges for construction, recommendations for risk/challenge mitigation.

Gather actionable insights from the contracting community to help refine the contracting approach, risk allocation, performance metrics, and the formal solicitation documents prior to release.

Continuing Authorities Program (CAP) 206 – Aquatic Ecosystem Restoration

• Under the authority provided by Section 206 of the Water Resources Development Act of 1996, the USACE may plan, design and build projects to restore aquatic ecosystems for fish and wildlife.

• Projects must:

• improve the quality of the environment;

• be in the public interest; and

• be cost-effective

Objectives

• Restore native oyster reef habitat to increase the oyster population and increase fish abundance and diversity.

• Restore tidal wetland shoreline habitats that support native wetland vegetation and the associated invertebrate community including native Atlantic ribbed mussel habitat.

• Restore the river-shoreline interface that provides important stopover and foraging habitat for migratory shoreline and wading avian species.

• Conduct habitat restoration that support a self-sustaining estuarine system

PROJECT AUTHORITY AND OBJECTIVES

Mussel Restoration: restore and improve habitat quality for native Atlantic Ribbed Mussels (Geukensia demissa)

• Existing population within the existing wetlands

• Paired with wetland restoration measures

Oyster Restoration: restore native oyster (Crassostrea virginica) habitat

• Placement of artificial substrate such as rock or pre-cast reef structures

• Optimize design and placement for both oyster habitat and wave attenuation for the wetland and bank restoration

Bank Restoration: restore bank/beach habitat

• Sandfill and native beach grasses such as Spartina patens and

Ammophila breviligulata

• Expected to be paired with oyster restoration to provide toe protection

Wetland Restoration: restore tidal wetland habitat

• Sandfill and native wetland vegetation planting such as Spartina alterniflora and Spartina patens

• Expected to be paired with oyster restoration to provide toe protection

QUESTIONS

QUESTIONS

• What is your recommended construction sequencing for this project?

• Is this project more feasible to conduct by barge or land or both? Given the shallow bathymetry of the project site, what is the maximum draft of the barges and tugs you would deploy, and how do you plan to operate during low tide cycles?

• How do you propose staging and transporting thousands of tons of stone and sand fill, in the upland staging areas?

• How would you propose access to the east wetland area?

• What GPS-guided equipment or specialized marine excavators do you use to ensure precise placement of oyster sills within the permitted footprint?

• Have you seen issues with supply of native wetland vegetation (e.g., Spartina alterniflora) on other projects?

• What would be your best management practices to preserve the existing mussels on site for incorporation to be replanted back into the sills?

• Period of performance recommendation?
