Abstract: The Section 227 National Shoreline Erosion Control and Demonstration Program provides authorization by which innovative shore protection devices, designs, and methods can be constructed, monitored and evaluated for functional performance and structural integrity. The objectives of the program are to: a) assess and advance the state of the art of shoreline control technology, b) develop and encourage the development of innovative solutions to shoreline erosion, and c) communicate findings to the public, state, and local officials in order to develop means for advancing the use of well-engineered alternative approaches to shoreline erosion control. The project site is located in Jefferson County southwest of the Sabine Pass and northeast of High Island, Texas in an area of actively eroding shoreline. The site area is completely undeveloped and is characterized by a broad salt marsh having a muddy substrate. Beaches are narrow and steep and are composed of mud or a thin veneer of sand and shell over mud. Sediment supply is negligible and the shoreline is actively eroding at rates between 1.5 m/y and 3.0m/y. Tides are mixed diurnal and semi-diurnal and tidal ranges are mostly limited to one to two feet. Wave heights average less than three feet although storm waves regularly flood the adjacent land and deposit washover terraces of sand and shell. Frequent flooding and long-term shoreline retreat have destroyed much of State Highway 87 adjacent to the McFaddin National Wildlife Refuge.
