Pono Kai Water Quality Assessment Seawall Repair

The Pono Kai Seawall is located on the eastern coastline of the island of Kaua’i. It was significantly damaged from years of exposure to high tides, heavy rains, and pounding surf. The seawall was to be repaired by constructing a sheet pile wall with a rock toe and adding beach nourishment. However, the repair project could result in suspended sediment that might degrade water quality in the area around the project site, possibly causing harm to wildlife and vegetation. During the construction, water quality had to be continually assessed to determine any degradation of water quality.
