VIMS presence in Portsmouth

• Elizabeth River Project, Board of Directors 16 years.

• Technical assistance, Portsmouth Wetlands Board

• Designs for wetlands at 4 Norfolk Naval Shipyard superfund sites.

• PAH toxicity and clean up, new technology. • PAH toxicity and clean up, new technology.

• Port expansion at Craney Island - modeling and mitigation.

• Continuing tide sensing for circulation and storm surge modeling.

What about PAH? Can we make an oil spill detector?

Compensatory Mitigation Plan for Port Expansion at Craney Island

• Environmental Impacts

• Filling 522 acres open water and submerged bottom habitat

• Loss of fisheries habitat

• Loss of benthic habitat

• Compensatory actions.

• Toxic Sediment Remediation: Dredging to remove highest concentrations and sand caps to isolate remaining contaminants

• Wetland Restoration with • Wetland Restoration with fisheries habitat benefits: Excavate disturbed upland areas to create salt marsh habitat

• Restore previously disturbed tidal wetlands

• Oyster Reef/Clam Ground Restoration
