This drainage improvement project for the Florida Department of Transportation – District 2 was designed to alleviate some of the most flood prone areas of Jacksonville Beach, Florida. SR A1A (3rd street) had seen widespread flooding after major weather events due to insufficient drainage at the existing outfall drainage channel.
This project included multiple critical components to address the drainage challenges of the area. CHC maintained bypass pumping for the project’s full duration so the drainage canal could remain active while improvements were being completed. The existing channel was cleared of all debris and vegetation in order to improve drainage capacity.
CHC furnished and installed over 8,000 LF of steel sheet pile wall using specialized non-vibratory equipment and techniques. These methods were chosen because of the proximity of the installation to existing structures in the community and the need to protect the structures for all stakeholders.
The scope of work also included a full replacement of the Kings Road Bridge with rigid inclusion soil stabilization to improve the approach ramps. CHC also replaced 4 channel crossings to increase drainage capacity.
