Document Description
The intent of the project is to identify viable options for the stabilization of the seawall in its present deteriorating state and extend the life of the seawalls. An investigation of the distressed concrete sheet pile seawall, was performed to analyze its stability, and develop repair concepts. Engineers have assessed the various factors contributing to the seawall's horizontal, vertical, and rotational displacements from the original constructed positions. Interim as well as long range have been recommended. Interim repairs would consist of sinkhole repairs (gravel filled bag system beneath sinkholes), a tieback system (grouted rods to relieve stress), and scour repairs (underwater rock protection). Since the existing seawalls are currently 70 years old, a replacement program (long range repairs) was also recommended. Long range repairs would include the option of waterside or landside repairs.
