At the Blackwater National Wildlife Refuge in Cambridge, Maryland, B&N led a project that created a wildlife viewing experience within the tidal marsh for visitors to enjoy. The project was completed for the U.S. Fish and Wildlife Service (FWS).

About 200 linear feet of elevated boardwalk and a 20-foot by 20-foot elevated observation platform were added at the Wildlife Refuge. B&N provided site surveys, preliminary and final designs.

The 8-foot-wide boardwalk was designed to provide visitors with full accessibility to meet ADA requirements. It also complies with the Maryland Department of the Environment (MDE) requirements for construction of a boardwalk within tidal marshlands.

B&N completed the project over two phases:

  • Phase I included site investigations during design development. The team also provided design services to prepare final bid documents based on conceptual layouts approved by the FWS.
  • Phase II included construction administration services and reviewing shop drawing submittals. B&N also completed periodic site observations during construction to confirm that work was performed according to the approved plans and permits.
