[ARCHIVED] Public Comment Period - Tar Pamlico River Basin Flood Risk Management Study


The U.S. Army Corps of Engineers (USACE) Pittsburgh District, Pittsburgh, Pennsylvania has prepared the draft Integrated Feasibility Report and Environmental Assessment (IFR/EA) for the Tar Pamlico River Basin Flood Risk Management Study, dated October 2023. An electronic version of the draft IFR/EA is available on the USACE Pittsburgh District website at:

The draft IFR/EA addresses the development, evaluation, and comparison of alternative flood risk-management plans and describes the draft recommendation—or tentatively selected plan—for federal action to reduce flood risk and damages along the Tar River and its tributaries.

The tentatively selected plan for the Tar Pamlico River Basin Flood Risk Management Study includes applying nonstructural-flood risk-reduction measures—or measures applied to a structure and/or its contents that prevent or reduce the damage from flooding—to 157 structures including:

a. Structure elevation and/or flood venting – 61 structures

b. Dry floodproofing – 96 structures

Only habitable structures would be eligible for inclusion in the nonstructural recommendation. The tentatively-selected plan includes elevating 2 structures, elevating and flood venting 7 structures, flood venting 4 structures, and dry floodproofing 22 structures along Stony Creek in the vicinity of Nashville and Rocky Mount, NC; elevating 1 structure, elevating and flood venting 5 structures, flood venting 4 structures, and dry floodproofing 10 structures along the main stem of the Tar River in the vicinity of Rocky Mount, NC; elevating and flood venting 1 structure and dry floodproofing 9 structures in in the vicinity of Tarboro, NC; and elevating 32 structures, elevating and flood venting 5 structures, and dry floodproofing 54 structures in the vicinity of Greenville, NC.

Structure elevation raises a house or building so that the lowest floor is above the 1% annual exceedance probability event (i.e., an event with a 1% change of occurring in any given year or that occurs on average once every 100 years) plus two feet. Flood vents protect houses and buildings during floods by preventing hydrostatic pressure buildup that can destroy walls and foundations. Structure elevation and flood venting can be used independently or in combination with one another, depending on the individual structure characteristics. Dry floodproofing involves sealing building walls and openings to prevent the entry of flood waters and is most applicable in areas of shallow, low-velocity flooding. Structures are dry floodproofed to the 1% annual exceedance probability event plus two feet, or a maximum height of four feet. Dry floodproofing is only applicable to non-residential structures.

The draft IFR/EA has been prepared in accordance with the Council on Environmental Quality and USACE requirements for implementing the National Environmental Policy Act (NEPA) of 1969 (33 CFR 230), as amended, and addresses the relationship of the proposed action to other applicable federal and state laws and executive orders. The draft report addresses the impacts of the tentatively selected plan on environmental resources, including, but not limited to federally listed threatened and endangered species, archaeological and historical resources, wetlands, fish and wildlife habitat, soils, and water and air quality. This public notice is being distributed to notify all known interested persons of the availability of the draft IFR/EA for review. A Finding of No Significant Impact (FONSI) pursuant to NEPA would be completed by the USACE if comments received during the review period indicate that a FONSI is appropriate.

Commenting Information:

Comments must be submitted in writing via regular mail or email within 30 days of the date of this notice. The USACE Pittsburgh District will consider these comments in determining whether a Finding of No Significant Impact (FONSI) or Environmental Impact Statement (EIS) would be completed.
