Coastal and Marine Engineering


The coastal environment produces specific challenges such as waves, storm surges, sea level changes, sea water, and the marine ecosystem. Our coastal and marine engineering team is trained to handle these challenges, and provide expertise in the planning, permitting and design of coastal and marina facilities. Our experience includes various types of shoreline revetments, seawalls, bulkheads and moorings as well as full service recreational and commercial marina facilities. We have designed over 60,000 linear feet of new and rehabilitated seawall and over 4,000 marina slips.

What Clients Say

It has been a pleasure to work with GRAEF. There are only a few consultants I’m willing to say this to. With GRAEF's diligence and excellent communication, they have made this project go much easier than it could have been. I will keep GRAEF in mind should another suitable project come across my desk.
