SR A1A RECONSTRUCTION AND STORM PROTECTION FLAGLER COUNTY, FLORIDA

In 2016, Hurricane Matthew, packing 90 mph winds, grazed the east coast of Florida just 20 miles offshore, taking what became known as “shark bites” out of the SR A1A coastal road in Flagler Beach, about 20 miles north of Daytona Beach. The storm took out chunks of roadway, in uneven swaths up to half the roadway width, for a distance of 1.4 miles.

 FDOT performed emergency repairs and built a temporary road realigned to the west of the original SR A1A alignment.  The FDOT design team is currently designing the permanent repairs.

GEC provided the subsurface investigation and geotechnical engineering recommendations for retaining wall design and construction.  To protect the sensitive environment and limit traffic impacts during the field investigation, GEC used a small, track-mounted drilling rig to perform the soil borings.  Construction is estimated at $40M. Completion is projected for late 2019.
