Manhole and Embankment Repairs
OWASA will repair a series of manholes and sections of armored embankment that have been damaged. Below is a FEMA notice regarding public comments on the project.
FINAL PUBLIC NOTICE
Orange Water and Sewer Authority (OWASA) has applied for Federal Emergency Management Agency (FEMA) Public Assistance (PA) Program funding through North Carolina Emergency Management (NCEM) as a sub- recipient.
Under the National Environmental Policy Act (NEPA), federal actions must be reviewed and evaluated for feasible alternatives and for social, economic, historic, environmental, legal, and safety considerations. Under Executive Order (EO) 11988 and EO 11990, FEMA is required to consider alternatives, and to provide a public notice of any proposed actions in or affecting floodplains or wetlands. EO 12898 also requires FEMA to provide the opportunity for public participation in the planning process and to consider potential impacts to minority and low-income populations. This notice may also fulfill requirements under Section 106 of the National Historic Preservation Act (NHPA).
Funding for the proposed project will be conditional upon compliance with all applicable federal, tribal, state, and local laws, regulations, floodplain standards, permit requirements and conditions.
Sub-Applicant: Orange Water and Sewer Authority

Special Flood Hazard Area Zone:
This project is for the replacement of rip rap and surge rock at four (4) sections of armored embankment and three (3) armored manholes around Orange County, North Carolina, which protect a larger system of water and sewer lines. All work is located in a Shaded X Zone (0.2% Annual Chance Flood Hazard), AE Zone (1% Annual Chance Flood Hazard), and Floodway.
Confirmation of location in a Special Flood Hazard Area (SFHA) was determined by the Orange County Flood Insurance Rate Map, Panel Numbers: 3710978700K and 3710988000K, dated 11/17/2017 and 3710978900K, dated 02/02/2007. The proposed work conforms to all applicable State of North Carolina and local floodplain regulations. There is a potential for the facility to be impacted by future flooding events due to its location within the floodplain and floodway. The proposed work will not take place in wetlands per the United States Fish and Wildlife Service National Wetlands Inventory and will have little potential to impact or affect wetland values.
Proposed Work and Purpose:
Orange Water and Sewer Authority will repair four (4) sections of armored embankment and the armoring around three (3) manholes for stabilization using 38.26 tons of surge rock and 126.08 tons of rip rap. The three (3) manholes and four (4) sections of embankment, will be repaired to pre-disaster conditions. The armoring will minimize debris impacts and reduce service line interruptions and leaks.
Alternative #1 (No action): The ‘no action’ alternative would ultimately result in a negative impact on Orange Water and Sewer Authority. If the embankment is not repaired, the manholes, water and sewer lines could be exposed, destabilized, and possibly damaged in the next flood event.
Alternative #2 (Relocation): Relocating the utility lines and associated manholes is not practicable because this is a part of a larger utility system and sections of the system must be located in the floodplain to serve the surrounding community.
Comments are solicited from the public; local, state or federal agencies, and other interested parties in order to consider and evaluate the impacts of the proposed project. The comments should be made in writing and addressed to:
FEMA Internal 11988 Reviewer
