JETTIES AND GROINS
Groins are structures that interrupt the flow of sand for the purpose of widening an already existing beach and thus provide additional protection for the beach. Jetties are similar to groins but are much larger. Both of these structures are usually placed perpendicular to the shoreline, but they may be offset. They are not designed for the purpose of creating a beach. Pre-application meetings and design by certified engineers are strongly urged for these projects
