Project details

  • Project Name: Marcus Hook Range Lights Rebuilding
  • Project Client: U.S. Coast Guard
  • Project Location: Wilmington, Delaware

A.D. Marble prepared required permits and assisted with consultation under the Endangered Species Act (ESA) and the National Historic Preservation Act (NHPA) for a project to replace two U.S. Coast Guard (USCG) range lights. The project included the demolition of the existing offshore Front Range Light, located within the Marcus Hook Bar Channel, and the disestablishment of the existing Rear Range Light, located inland within a historic lighthouse. In order to provide a safe navigational range line that satisfies channel requirements and present-day vessel characteristics, two new offshore structures were constructed within the Delaware River, north of Wilmington, Delaware.

A.D. Marble assisted with the NHPA Section 106 consultation, including preparing consultation letters and drafting a Memorandum of Agreement (MOA) between the USCG and the Delaware State Historic Preservation Officer (DE SHPO). A.D. Marble also conducted mitigation required under the MOA.
