Abstract: The proposed action is to institute beneficial use (BU) of dredged material excavated during routine periodic maintenance dredging along part of the Galveston Causeway to Bastrop Bayou reach of the Gulf Intracoastal Waterway (GIWW), to protect and restore marsh habitat. The segment being addressed involves a two-mile reach of channel in Galveston County, Texas. The subject reach of the GIWW begins approximately seven miles west of the Galveston Causeway and includes the channel and the immediate environs. The proposed BU area is depicted in Figures 1 and 2. The GIWW was constructed in the 1940s with an alignment through marshes and bayous in the region. Over the years, erosion and subsidence resulted in a transition of some historically fresh/intermediate marsh to a more saline condition. If no action is taken, salt-water intrusion will continue this transformation.
