Milestones
Project Description
Hurricane Dorian impacted the shoreline of Edisto Beach around 5–6 September 2019. The storm produced high water levels (surge), increased wave energy, and tropical-storm-force winds as it passed inland. Offshore wave heights were measured at 7.5 meters (m) (~25 feet [ft]) during the storm. The storm passed just offshore of Edisto Beach, with the eye located about 70 miles offshore at 1200 UTC on 5 September. At that time, Dorian was a Category 3 storm with ~115 mph winds.
To restore the sand quantity lost from the project area, the Town of Edisto Beach intends to add the same quantity of sand to the beach using sand imported from an upland source. This will require trucking in the sand from an upland source using beach compatible sand and adding it to the areas that were eroded.
The total volume loss for the storm (34,383 cy) includes background erosion. CSE stated that the “project area averages a loss of 41,278 CY per year, as determined from total losses between 2006 and 2015. Applying this value over five weeks (the interval between pre- and post-storm surveys), yields a five-week loss of 3,969 CY. Subtracting the background erosion from the measured losses provides a total storm-induced loss of 30,414 CY.”
The total incident-related sand loss for the Project is 30,414 CY.
The estimated project cost is $678,280.
If approved by FEMA, they would provide reimbursement of 75% or $508,710.
ATAX approved funding $320,000.
