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.

The project is progressing as scheduled.  The contractor worked later than normal last night in order to move sand around Coots during low tide.  They are not placing sand under the pier due to safety and liability concerns.  The contractor should be finished with the front beach work this week and move to Beach Access 28 later this week. 

On February 5th there were 57 loads of sand placed on the beach.

On February 8th there were 70 loads of sand placed on the beach. 

On February 9th there were 56 loads of sand placed on the beach.

Project Update February 3, 2021
Wednesday, February 3, 2021

The project is moving along quickly.  The contractor is working between groins 3 and 4. 

Yesterday they placed 1,312 cubic yards of sand between groins 3 and 4.  On February 1, 2021 they placed 1,520 cubic yards of sand between groins 3 and 4 and January 29, 2021, they placed 1,408 cubic yards of sand between groins 4 and 5.  

The contractor has started sweeping the road again after resolving equipment issues.  The Town has requested that the scarped areas be tapered daily and that they complete the dune work in each area daily before moving to the next area.  

Next week the contractor should be working around beach access 28.  This will increase traffic on Palmetto Blvd.

Yesterday construction commenced.  The contractor delivered a total of 71 loads of DHEC approved sand running 12 trucks.  The sand has a reddish hue which is due to a higher iron content then dredged sand and should become lighter over time.
