Flood Protection Permits

C-4 EDB permit provides improved flood protection. The individual permits are as follows: The C-4 EDB provides improved flood protection for the City of Sweetwater and surrounding areas during extreme storm events by providing 3,264 acre-feet (ac-ft) of aboveground storage for floodwaters. During a major storm event, the C-4 EDB pumps convey floodwaters from the C-4 canal into the storage detention basins (both Phase I and Phase II), which helps reduce flooding of the area further east. After the event and stages in the C-4 canal have returned to normal, the floodwaters discharge from the EDB back to the C-4 canal and eventually to tide. Construction of the water management infrastructure was certified complete in May 2005, and the facility became administratively operational in November 2006.
