Army Corps of Engineers Flagler County Coastal Storm Risk Management Project Information

Flagler County Hurricane and Storm Damage Reduction Project

Flagler County ShorelineThe primary purpose of an HSDR project is to reduce storm damage to coastal infrastructure, including residential and commercial property and public facilities. Opportunities to reduce the risk of coastal damages and improve eroded conditions were examined and approximately 9.7 miles of Flagler County coastline were investigated during the feasibility study process.

Beach and dune erosion, both long-term and storm induced, is the greatest problem in the Flagler County area. Due to unique beach sediments and the closeness of State Road A1A and existing coastal development, the county’s dune system is experiencing a long-term erosion trend with little opportunity for natural recovery. The establishment of a functional dune system is key to reducing damages to infrastructure and maintaining environmental quality. State Road A1A is the only north-south hurricane evacuation route for communities along the coastline, which makes it essential for public safety during evacuation events.

The Corps’ plan will provide additional armoring and protection of upland infrastructure, including SR A1A.  The project consists of a 10-foot seaward extension of the existing dune along 2.6 miles between 7th to 28th streets in central Flagler Beach. Construction of the dune will extend the existing berm and the entire active profile seaward.

To build the berm, the Corps anticipates dredging sand from an offshore borrow site and pumping it onto the adjacent beach.  “We expect that initial construction will cover some vegetation, but new vegetation, similar to the existing foliage, will be planted following construction completion,” said Corps Project Manager Jason Harrah. The Corps also anticipates renourishment events would occur every 11 years to repair eroded areas.
