The Bayou Caddy Ecosystem Restoration (Shoreline Stabilization) project is located in southwestern Mississippi near Waveland, in Hancock County. The project site is adjacent to and west of the federally authorized Cadet Bayou navigation project. Cadet Bayou is about 21 miles to the west of the Port of Gulfport and is about 44 miles to the east of New Orleans, Louisiana. The Bayou Caddy Ecosystem Restoration Project consists of a 22-acre site of restored marsh contained by a 2,000-foot-long geotextile tube (Figure 1). The most recent portion of the project consists of a 1,000-foot-long by 25-foot-wide rock breakwater combined with a 1,700-foot-long segmented living shoreline system consisting of prefabricated concrete wave attenuation devices (WADs) that protect the ecosystem restoration project from excessive wave action and storm damage as seen in the figures below. Based on the preivous field survey team, the acreage of the phragmites was approximately 1.2 acres but may have changed since last field visit in Spring ’24

This project entails an herbicide treatment of phragmites, an invasive plant identified during recent post-construction monitoring events, within four areas of the 22-acre restored marsh (Figure 2). The goal is to remove phragmites without causing damage to restored marsh plantings. This is intended to be a one-time spray treatment, after which additional follow-up or annual control treatments may be required, depending upon the results. Contractor shall provide all equipment, materials, transportation, and personnel required to accomplish the tasks described herein.
