Duval County Shore Protection Project

The Duval County Shore Protection Project was initially constructed in 1978-80. Since then, six principal renourishments have been completed (1985-87, 1991, 1995, 2005, 2011 and 2016-17) in addition to periodic placement of maintenance-dredged sand.


Jacksonville District is presently producing plans and specifications for the next scheduled beach renourishment, which will address the impacts of two 2022 tropical storms, Ian and Nicole. Required permitting and certification by the Corps and its partner agencies are scheduled to be complete in September 2023. The Corps expects to award a contract for beach renourishment before the end of the year and work is planned to begin by the end of February 2024.


Beach renourishment takes place every five to six years in order to maintain beaches at their original design dimensions as part of the project. The renourishment is funded in partnership with the City of Jacksonville, Florida Department of Environmental Protection, and Duval County, with 38.4 percent of funding provided by the local partners and 61.6 percent by the federal government. The U.S. Army Corps of Engineers manages the project throughout its 50-year lifecycle. 


The goal of engineered shore projects is to reduce risk and promote coastal resilience. Shore projects help to reduce the damages – economic, environmental, infrastructure, human health and safety – of tropical storms and hurricanes. Thousands of residents and businesses in Duval County benefit from this shore project because storm events erode the beach rather than destroying coastal infrastructure. Coastal communities with engineered beaches have historically fared much better than other communities as documented by numerous studies.


Each renourishment corresponds to an engineer-designed template so that when storms occur, they affect the sand placement in the template and reduce impacts to the underlying beach foundation and landside infrastructure. The engineering design, informed by wave and tidal flow analysis, makes best use of the natural system to preserve sand on the beach. 


Along with protecting coastal economic stability and recreational opportunities, beach nourishment projects also provide inherent benefits in restoring critical marine and shorebird habitat. It provides more sand for endangered sea turtles, which normally nest on the same beach where they hatch, to find sufficient areas for nesting. Several species of shorebirds also nest along the beach. And, of course, the beach is essential to the area’s economic driver, tourism.


2016-17 Project Description: The Duval County shore protection project nourished eroded beaches and rebuilt dunes devastated by Hurricane Matthew’s passing in October 2016. The City of Jacksonville funded the additional dune work that included building dunes in Jacksonville, Neptune and a portion of Atlantic Beach. More than a million cubic yards of sand – equivalent to more than 2.7 billion pounds – was dredged, piped and tilled across about ten miles of county shoreline. Roughly 860,000 cubic yards went to building the beach and another 200,000 cubic yards went to rebuilding dunes. Construction started in mid-September 2016 to widen the beach berm between 20 to 60 feet, and raise the elevation of the beach by about 3 to 5 feet.  


In early October, Hurricane Matthew swept by and devastated much of the county’s beaches. The City and the Corps took swift actions to recover and move forward with surveys and a contract that included dune work. Dredging stopped in December as originally scheduled, and resumed again in April 2017. Dredging was completed on May 24. The contractor excavated sand from four offshore borrow areas located in federal waters. Construction is estimated at $13.57 million.
