Barnacle Historic House Boathouse and Dock Repairs

Miami-Dade County, Florida

Project Description

The Barnacle Historic State Park is situated in Coconut Grove, Miami overlooking the Biscayne Bay. The historic boathouse and dock sustained damage in 2017 as a result of Hurricane Irma. Given the park’s historic designation, a key goal was to restore the boathouse and dock consistent with the original appearance.

WGI conducted an environmental assessment to document protected resources (e.g., seagrasses, mangroves) to determine the level of environmental permit authorizations required to conduct repairs. The project required preliminary coordination and permits through the South Florida Water Management District Environmental Resource Program, the U.S. Army Corps of Engineers Section 10 of the Rivers and Harbors Act of 1899, and the Miami-Dade County Department of Regulatory and Economic Resources Division of Environmental Resource Management Coastal Resources Section.

WGI environmental scientists and structural engineers implemented avoidance and minimization measures to protect natural resources while restoring historical resources. WGI conducted research to gain a thorough understanding of the park’s historical permits and represented the FDEP at preliminary regulatory agency coordination meetings to successfully negotiate repairs qualifying under maintenance to expedite the permitting process. This included establishing historical areas of mangrove trimming and seedling removal to restore historical bay views, protect historic structures, and maintaining navigational access for non-motorized vessel use.
