Draft Supplemental Environmental Assessment Town of Oak Bluffs Resilient Infrastructure for East Chop Drive

Final Supplemental Environmental Assessment, Town of Oak Bluffs Resilient, Infrastructure for East Chop Drive, Town of Oak Bluffs, Dukes County, Massachusetts, PDMC-PJ-01-MA-2018-001

The Massachusetts Emergency Management Agency submitted to the Federal Emergency Management Agency (FEMA) a Pre-Disaster Mitigation (PDM) grant application on the behalf of the Town of Oak Bluffs (Town). The PDM Grant Program is authorized under Section 203 of the Robert T. Stafford Disaster Relief and Emergency Assistance Act, 42 United States Code (U.S.C.) 5133. Under the PDM grant program, FEMA may provide technical and financial assistance to states and local governments to assist in the implementation of pre-disaster hazard mitigation measures that are cost-effective and are designed to reduce injuries, loss of life, and damage and destruction of property, including damage to critical services and facilities resulting from natural disasters.
The Proposed Action would stabilize and improve 1,200 linear feet of a failing coastal revetment along East Chop Bluff. The revetment experienced erosion that has undermined the existing road, East Chop Drive, to the point of imminent failure.
The National Environmental Policy Act (NEPA) requires FEMA to consider potential environmental effects before funding or approving actions and projects and to ensure that the public is fully informed about the potential consequences of a proposed federal action. The United States Army Corps of Engineers (USACE) completed an Environmental Assessment (EA) and a Finding of No Significant Impact (FONSI) on January 21, 2020, for this project. USACE issued a permit to the town under Section 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. § 403) and Section 404 of the Clean Water Act (CWA) (33 U.S.C. § 1344) (USACE file number NAE 2017-01616) on January 21, 2020. The project reviewed in the USACE EA included 2,400 linear feet of revetment work from the toe of the revetment up to the high tide line (HTL). The work proposed for funding under the FEMA grant would include the southern 1,200 linear feet of the area reviewed by USACE and would also include work above the HTL up to the western side of East Chop Drive.
FEMA is proposing to adopt the USACE EA in accordance with Title 40 Code of Federal Regulations (C.F.R.) 1506.3(c) because the actions covered by the original environmental assessment and the Proposed Action are substantially the same below the HTL. Because the project proposed for funding under the PDM grant program encompasses a larger area than considered in the USACE EA, FEMA has prepared this Supplemental Environmental Assessment (SEA) to evaluate the potential effects of the Proposed Action and alternatives that were not analyzed in the USACE EA. FEMA will use the findings in this final SEA to determine whether to prepare an environmental impact statement or to issue a FONSI.

The Massachusetts Emergency Management Agency, the grant applicant, submitted to FEMA a Pre-Disaster Mitigation (PDM) grant application on behalf of the Town of Oak Bluffs (Town), the grant subapplicant. The PDM Grant Program is authorized under Section 203 of the Robert T. Stafford Disaster Relief and Emergency Assistance Act, 42 United States Code (U.S.C.) 5133 and provides assistance to eligible state, territory, and local governments, as well as federally recognized tribal governments to help implement sustained pre-disaster natural hazard mitigation programs.
The Proposed Action would stabilize and improve 1,200 feet of a failing coastal revetment along East Chop Bluff. The purpose of the proposed project is to reduce erosion hazards along East Chop Bluff. The project is needed because the existing revetment is failing due to continued erosion caused by wave and storm surge action. Erosion has deteriorated the existing revetment and reduced the vegetation on the bluff, thereby destabilizing the slope and posing a threat to nearby residential homes. Additionally, because the roadbed is undermined by the continued erosion, East Chop Drive is currently closed, impacting evacuation routes and emergency response.
