Fifi Island is located on the north side of Grand Isle, LA.The island plays a major role in protecting the coast from hurricane storm surge. Fifi Island serves as a wave break to protect the Bayou Rigaud navigation channel and the northeast shoreline of Grand Isle from wave action when severe weather from the north produces high energy waves in Barataria Bay. Fifi Island has experienced rapid land loss especially on its eastern tip, leaving the Bayou Rigaud navigation channel and the northeast shoreline of Grand Isle unprotected.
Digital Engineering provided complete design, bidding, construction administration, and resident inspection services for this shoreline protection project. DE prepared the application for the necessary permits and provided design plans and specifications to construct a rubble mound breakwater that extends east of Fifi Island along Bayou Rigaud to protect the north side of Grand Isle, Louisiana from wave action.
The project also included design of a dredged access channel for construction of the breakwater. Construction was completed in August 2013.
