Full Public Notice Project Plans
The applicant proposes to a construct a combination of graded riprap breakwaters and graded riprap revetment for shoreline protection as a form of bank stabilization. The purpose of the project is to provide protection to a demonstrably eroding shoreline containing estuarine wetlands and seagrass. The applicant has stated that erosion along the shoreline of Indian Point Park can be significantly reduced with the addition of shoreline protection that shields the bank and adjacent wetlands from waves caused by wind generated across Corpus Christi Bay. As waves impact the structure, they will break and dissipate energy. The reduction in wave energy mitigates erosion along the shoreline and provides shelter for seagrass. The shoreline protection includes a combination of both segmented breakwaters and revetment. The total length of shoreline protection structure is 2,800 feet. This length includes 8 segmented breakwaters and a revetment. The breakwaters would be placed a minimum of 20 feet away from the nearest seagrasses. Each breakwater would be between 200 and 500 feet in length with approximately 30-foot gaps between each segment. The structures would impact approximately 2 acres of non-vegetated bay bottom in which approximately 3 to 4 cubic yards per linear foot of segmented breakwater graded riprap will be placed below mean high water (MHW) and approximately 2 to 3 cubic yards per linear foot of revetment graded riprap will be placed below MHW. The applicant has proposed to have the option of protecting the shoreline in the southernmost portion of the project area with either riprap revetment or two additional off-shore breakwaters.
