MORRISTOWN, N. J. — On behalf of New York City, Louis Berger is restoring a degraded urban wetland on Staten Island, the Saw Mill Creek Pilot Wetland Mitigation Bank, to demonstrate a viable economic strategy to restore an impaired wetland habitat and improve resiliency in the city’s sensitive coastal areas. Following the successful completion of a lengthy process to obtain regulatory approvals for this first-of-its-kind project in New York City, construction is underway and the city’s first wetland mitigation credits are available for sale.

Since 2013, Louis Berger has been working closely with NYCEDC and other city, state and federal resource agencies to establish and construct the city’s first tidal wetland mitigation bank.

“To be prepared for future challenges, it is crucial that we incorporate resiliency in today’s projects,” said Niek Veraart, Louis Berger vice president of environmental planning. “We are honored to support New York City’s efforts to pilot wetland mitigation banking as a way to leverage public and private financial resources for restoration of degraded urban wetlands.”

Wetland mitigation banking is the restoration, creation, enhancement or preservation of a wetland, stream or habitat conservation area to compensate for impacts to similar regulated ecosystems nearby. It provides a more cost-effective means of restoring natural resources, reducing delays in permitting and assuring long-term maintenance of vital natural areas.

Since 2013, Louis Berger has worked closely with the New York City Economic Development Corporation (NYCEDC) and other city, state and federal resource agencies to establish and construct the city’s first tidal wetland mitigation bank. The pilot project is part of the Mitigation and Restoration Strategies for Habitat and Ecological Sustainability (MARSHES) initiative to explore policies and strategies to enhance and protect New York City’s coastal resources and restore contaminated wetlands while fostering sustainable waterfront development.

Under contract to NYCEDC, Louis Berger developed an ecological assessment methodology and conducted surveying and environmental testing, including sampling and wetland functional assessments. The company performed vegetation analysis, a threatened/endangered species analysis, and other planning, construction and design services that included a feasibility study, construction cost estimates and schedules, and restoration design plans for emergent wetlands, scrub-scrub wetlands, freshwater-forested wetlands, open water channels/pools, mudflat habitat, and uplands.

Located in an area that contains a mixture of industrially developed land adjacent to salt marsh and coastal forest, the Saw Mill Creek Pilot Wetland Mitigation Bank project is improving water and sediment quality, plant and wildlife diversity and wildlife species abundance on the western shore of Staten Island. Restoration actions have removed contaminated soils and debris from the site to create tidal channels and marshland planted with native wetland vegetation.
