Document Description
The project is limited to the installation of a new sheet pile seawall (approximately 550 feet long) in front of the existing damaged concrete and masonry seawall which failed during the 2017 storms due to undermining and erosion. The new sheet piles will be driven as close to the existing seawall as practical and the void between the existing wall and new wall will be backfilled. The wall will have a concrete cap approximately two feet above the 100-year flood level to provide protection to the park facilities from wave action. It is anticipated that the sheet pile will be installed using vibratory hammers on the park side of the wall supported by excavators or cranes. Maximum pile depth below lakebed will be 25 feet. The project also includes the replacement of a set of concrete stairs to provide swimmer access to the beach and lake. The concrete sidewalk adjacent to the seawall on the park side will also be replaced.
