Manalapan Seawall Storm Protection Case Study

This case study details the construction and repair of the Manalapan seawall in Palm Beach, Florida, following the damage caused by Hurricane Sandy in October 2012. The document outlines the history of the area, highlighting the population growth and the initial construction of sea walls using PMA 22 steel sheet piles to protect oceanfront properties. It describes the significant damage inflicted by Hurricane Sandy, which resulted in the overtopping of the sea walls and subsequent flooding of properties. The homeowners' association, in collaboration with engineers, undertook the urgent task of replacing the damaged sea walls before the next hurricane season, adhering to regulations from the Environmental Protection Agency regarding sea turtle nesting. The solution involved the installation of new steel sheet piles, specifically coated AZ 26-700, designed for a 100-year life, and a T-wall design to enhance stability. The case study concludes with details on the materials used and the contractors involved in the project.
