FACT SHEET - Hudson Raritan Estuary (HRE) – Flushing Bay and Creek, NY Ecosystem Restoration

Ecosystem Restoration Study

U.S. Army Corps of Engineers, New York District
Published March 5, 2021

DESCRIPTION: The Hudson Raritan Estuary (HRE) is within the boundaries of the Port District of New York and New Jersey and is situated within a 25-mile radius of the Statue of Liberty National Monument. The HRE feasibility study area includes 8 Planning Regions: 1) Jamaica Bay; 2) Lower Bay; 3) Lower Raritan River; 4) Arthur Kill/Kill Van Kull; 5) Newark Bay, Hackensack River and Passaic River; 6) Lower Hudson River; 7) Harlem River, East River, and Western Long Island Sound; and 8) Upper Bay. The Flushing Bay and Creek Feasibility Study Area is located within the Harlem River, East River and Western Long Island Sound HRE Planning Region. 

The HRE and Flushing Bay and Creek feasibility studies’ purpose was to identify and document water resource related problems, existing conditions and factors contributing to environmental degradation within the estuary and specifically the Flushing Creek in order to develop potential solutions aimed at ecosystem restoration. The overall objectives of both studies were to restore ecological function and diversity that have been lost or degraded as a result of human activities. 

The USACE and multiple non-federal sponsors commenced HRE, the Flushing Bay and Creek and four (4) other concurrent ecosystem restoration feasibility studies in the 1990s and early 2000s that focused on the restoration of different areas of the HRE.  In an effort to streamline parallel efforts, and maximize efficiencies, resources and benefits, the feasibility studies were integrated into the HRE Feasibility Study effort between 2013 and 2015.  The HRE Feasibility Report and Environmental Assessment (FR/EA) fulfills the authorizations of all six (6) feasibility studies.

Implementation of the HRE Ecosystem Restoration Feasibility Study’s recommendations will enable the USACE, its non-Federal cost-sharing sponsors, and other regional stakeholders to restore and protect lost or degraded aquatic, wetland and terrestrial habitats within the HRE study area. These activities will be accomplished by implementing various site-specific ecosystem restoration projects formulated within the context of an overall strategic plan.

AUTHORIZATION:

Flushing Bay and Creek- Congress Resolution dated September 28, 1994, Docket Number 2442.

HRE- House of Representatives Committee on Transportation and Infrastructure Resolution dated April 15, 1999, Docket Number 2596.

 

STATUS: Federal interest was demonstrated to address ecosystem restoration and related water quality improvements for Flushing Bay and Creek in 1996.  A Feasibility Cost Share Agreement was executed with New York City Department of Environmental Protection (NYCDEP) and the Port Authority of NY/NJ in 1999. Data collection (including a Phase 1 environmental site assessment, tidal and current measurement program, water quality sampling program, finfish community surveys and benthic community surveys) occurred in 2001 and 2002 and NYCDEP conducted hydrodynamic and sediment transport analysis, benthic and fisheries surveys, bathymetric and land surveys, wetland and upland habitat characterization, sediment coring, geotechnical study and sustainability and hydrodynamic assessment between 2011 through 2014.

Twelve (12) sites were evaluated and a draft feasibility report/environmental assessment was prepared in 2007, but was not released to the public. The recommended restoration alternative was not supported by NYCDEP and required further coordination with the department’s combined sewer outfall (CSO) discharge long term control plans for Flushing Bay and Flushing Creek and with future environmental dredging in the bay and creek. Progress was suspended due to lack of funding and the study was inactivated. Recommendation for ecosystem restoration within Flushing Creek was identified as a priority within the Flushing Creek and Bay Study Area within the Harlem River, East River and Western Long Island Sound Planning Region and was subsequently integrated into the HRE study in 2013.

In parallel, the USACE identified a need for a strategic plan as a first step of the HRE Feasibility Study.  With participation of the regional stakeholders, the USACE and the Port Authority of New York and New Jersey developed a Comprehensive Restoration Plan (CRP) that now serves as the master plan and blueprint for future restoration within the HRE region.  The CRP provides the framework for an estuary-wide ecological restoration program by utilizing restoration targets -Target Ecosystem Characteristics (TECs) established through a collaborative effort among the region’s stakeholders in 2005 through 2007.  The CRP Program goal was to develop a mosaic of habitats that provide society with renewed and increased benefits from the estuary environment. Each TEC is an important ecosystem property or feature that is of ecological and/or societal value including restoration of coastal wetlands, shellfish/oyster reefs, eelgrass beds, waterbird islands, public access, maritime forest, tributary connections, shorelines and shallow habitat, fish crab and lobster habitat, reduction of contaminated sediments and improvement of enclosed and confined waters.  The CRP provides a strategic plan to achieve the TEC goals, identify potential restoration opportunities and mechanisms for implementation. The Draft CRP was released in April 2009 and was adopted by the New York/New Jersey Harbor Estuary Program (HEP) as the path forward for restoration in the future. Following intensive public outreach, CRP Version 1.0 was released in June 2016.

The HRE Feasibility Study recommended specific restoration projects throughout the HRE Study Area, including Jamaica Bay, that advance the CRP goals and provide solutions for water resource problems. Feasibility activities included the evaluation of a subset of priority CRP sites including ecological functional assessments, preparation of restoration alternatives, engineering designs and cost estimates, National Environmental Policy Act (NEPA) Environmental Assessments and Cost Effectiveness/Incremental Cost Analysis (CE/ICA) for each site.  In addition, other restoration opportunities outlined in the CRP were recommended for further feasibility study investigation which would require subsequent Congressional construction authorization.  A total of 33 sites were recommended as the Tentatively Selected Plan (TSP) in the Draft Integrated FR/EA released for public review in February 2017 following the TSP Milestone accomplished in August 2016.

The District had coordinated with the Vertical Team to address policy comments and completed additional tasks to confirm the TSP and ensure policy compliance (tasks included update of costs, ecological benefits, relative sea level change analysis and Planning Region CE/ICA evaluations).  Following completion of these tasks, the Agency Decision Milestone (ADM) was held on September 5, 2018 and 13 sites were removed from further consideration.  

Final feasibility level activities were completed for the remaining sites and the Final Integrated Feasibility Report and Environmental Assessment was submitted to HQUSACE on 11 February 2020 for review and approval. The State and Agency review occurred March 16, 2020 through April 15, 2020.  The Chief’s Report was signed by LT General Todd Semonite on 26 May 2020 making it eligible for congressional authorization. 

The Recommended Plan includes restoration at 20 individual project locations including a project restoring Flushing Creek. The HRE Recommended Plan will restore a mosaic of 621 acres of habitat that will reduce long-term and large-scale degradation in the Hudson Raritan Estuary for a total first cost of $408,868,000 and fully funded cost (escalated to mid-point of construction) of $588,745,000.

The Recommended Plan includes:

•   Restoration of approximately 381 acres of estuarine wetland habitat (including six miles of tidal channels), 50 acres of freshwater riverine wetland habitat, 27 acres of coastal and maritime forest habitat, 39 acres of shallow water habitat and 52 acres of oyster habitat.
•   Two fish ladders would be installed and three weirs would be modified to re-introduce or expand fish passage (24 miles) and control flow rate and water volume along the Bronx River.
•   A total of 1.6 miles of stream bank and 72 acres of stream bed and channel would be restored.
