Calhoun Port Authority Wetland Mitigation Project 

The Calhoun Port Authority was required to self-perform USACE required mitigation to offset impacts resulting from dredging related to construction of a new marine terminal. Based on the results of a site selection process, a 14-acre area along the shore of Lavaca Bay (the Bean Tract) was selected as the mitigation site. The designs include a 3-acre levee, 1 acre of channels to provide tidal inundation and circulation, 8.7 acres of low marsh and 1.7 acres of high marsh. The site was constructed by beneficially reusing recently placed dredge material from an upland disposal site. Material was hauled by trucks to the mitigation site and used to construct a protective levee around the exterior and as fill to increase elevations within the levee. Construction of the site was completed in January 2024 with the removal of the access roads and breaching of the dikes to allow tides to enter the site. The site will be allowed to settle/consolidate for a minimum of 60 days, as required by the permit conditions, and then be planted with locally field harvested plants. Initial planting will occur in the last spring / early summer, after 60 days an inspection will be completed to determine if plant survival meets the permit requirement. Any replanting required will occur in the fall and be coordinated with a community education event led by the Port. The event will showcase the Port’s operations in the Bay, discuss the job opportunities related to Port operations, and provide a hands-on opportunity to assist in helping with the wetland plantings. After the replanting, a long-term monitoring program will be initiated to document the establishment of the vegetation.
