Flood Risk Management Feasibility Study

Bookmark and Share Email Print

DESCRIPTION:

The Peckman River Basin is located in Essex and Passaic Counties, New Jersey. A tributary to the Passaic River, the Peckman River originates in the Town of West Orange and flows northeaster through the towns of Verona, Cedar Grove, Little Falls, and Woodland Park to its confluence with the Passaic River in West Paterson. Extensive development in the basin has resulted in flood damages and ecosystem degradation.

The Basin experiences frequent flooding from intense thunderstorms and heavy rainfall. These storms can deposit large amounts of precipitation in the watershed, producing significant runoff, which quickly surpasses the capacity of the river channel, including bridge and culvert openings.Significant degradation of the ecology of the Basin has occurred as a result of extensive erosion at specific locations along the river. The current state of the river ecosystem reflects the type of long-term degradation often associated with heavily urbanized watersheds. The development of the watershed has reduced the water-holding capacity of the landscape and altered the natural flow dynamics within the river system.

AUTHORIZATION: The U.S. House of Representatives, Committee on Transportation and Infrastructure, authorized a study of the Peckman River and Tributaries, New Jersey, by Resolution dated 21 June 2000. Initial Planning efforts were performed in accordance with Section 205 of the Continuing Authorities Program (CAP).

STATUS: A favorable reconnaissance report was completed in July 2001. The report recommended a feasibility study to develop alternatives for flood risk management in the Peckman River Basin. A Feasibility Cost Sharing Agreement (FCSA) was executed on March 14, 2002 between the Corps and the New Jersey Department of Environmental Protection (NJDEP). The New York District received a letter in December 2016 from the NJDEP Land Use Regulatory Program indicating their permitting support for the Tentatively Selected Plan (TSP). The New York District received a memo on August 11, 2017 from NAD/ HQ USACE authorizing the resumption of the feasibility study, which had been temporarily suspended in November 2014 over concerns with study time and cost.

Efforts within the Feasibility Study have resulted in the development of a number of alternative plans to reduce flood risks in the project area, identified as areas within the Township of Little Falls and the Borough of Woodland Park. Alternative 10b has been identified as the Tentatively Selected Plan (TSP), consisting of a diversion culvert and associated works in combination with nonstructural measures and ringwalls to provide flood risk management to the affected municipalities.

The Tentatively Selected Plan TSP also includes a floodwall system along Great Notch Brook, which, along with the diversion culvert, would provide flood risk management to Woodland Park. The ringwalls and nonstructural measures, consisting of elevation and floodproofing of structures, would provide flood risk management to Little Falls. The Draft Integrated Feasibility Report/Environmental Assessment and Appendices (DIRF/EA) was released for public review on 07 May 2018. The report identifies Alternative 10b as the Tentatively Selected Plan (TSP) and recommends that this alternative be further developed within the current Feasibility Study and recommended for design and construction, if warranted.The public review period occurred during the period from 07 May 2018 to 05 June 2018. Links to the DIFR/EA will be posted on the New York District website at www.nan.usace.army.mil by close of business on Monday, 07 May 2018.Prior to release of a later finalized version of the Feasibility Report, the TSP will be optimized to determine the size and scale of the plan that would relatively maximize project benefits and minimize project costs.The level of performance, size and scale, number of structures selected for nonstructural treatment, and cost of the Tentatively Selected Plan (TSP) are subject to change during optimization and prior to completion of the Feasibility Study.

Estimated Study Costs:

To date the study has received $2,759,707 in Federal funding. Additional Federal and non-Federal funding to complete the Feasibility Study have been received.
