IOP Shoal Management Overall Plan Map
BEACH RESTORATION TIMELINE in REVERSE CHRONOLOGY
March 16, 2015: Sand hauling for the shoal management project ended on February 19, 2015. The project transferred 240,00 cubic yards of sand fro accretional areas from 53rd through 56th Avenues and near Mariners Walk and Shipwatch. Approximately 70,000 cubic yards were placed along the Beachwood East/Dunecrest area, and 170,000 cubic yards were placed near Seascape, Ocean Club and the 18th hole of the Links golf course. The total cost of construction was approximately $926,000, which is equivalent to a net cost of $3.87 per cubic yard hauled. This compares to average costs of offshore nourishment sand ranging between $8 to $10 per cubic yard. Even with the addition of sand with the project, configuration of the approaching shoal is continuing to cause erosion, especially during high wave and tide events. It is likely that some areas of the project will need additional mitigative measures prior to the next permit window for another shoal project which is November 2015 - April 2016.

February 20, 2015: Sand hauling for the project has been completed. Baker will continue to grade the fill this weekend with the bulldozer and will be removing equipment and materials through next week.
February 18, 2015: Based on the condition today, Coastal Science and Engineering instructed Baker to split the remaining fill between both fill areas. Two trucks will be hauling to the western fill area and one to the eastern fill area. Filling will continue through Friday afternoon. Baker is presently shaping the fill with the bulldozer to the design elevation. This may continue after Friday, but no additional sand will be hauled after Friday.
February 9, 2015: Baker is currently working every day, all day during daylight hours to harvest sand from the intertidal beach between Shipwatch and the Property Owners Beach House. Sand is primarily being placed in the eastern fill area. Work is expected to continue through late February, but the schedule is subject to change.
Feburary 2, 2015: Construction has resumed, and work this week will continue off the shoal. Currently, Baker does not plan to work on Sunday, February 8th or Monday, February 9th. Work on Saturday, February 7th will depend on conditions. The City appreciates the continued patience of residents and visitors. Please keep a safe distance from the project and the equipment.
January 28, 2015: View a ground-level and aerial photo gallery of the project.
January 23, 2015: As work progresses, the shoal is becoming lower, meaning less sand is visible during normal and neap (higher low) tides. There is still sand available during spring tides. Baker has been consistently productive for the past two weeks. The design quantity has been placed along the Beachwood East/Duncrest area, and remaining sand will be placed solely in the eastern fill area. Areas needing regrading to the design template will be determined towards the end of the project. Construction will not occur from Sunday, January 25 through Wednesday, January 28.
January 13, 2015: Baker continues working to harvest sand from the shoal and place it at both fill locations. Work will continue in this fashion this week and over the weekend. The next scheduled break is Janury 24th-26th.
January 5, 2015: R.B. Baker continues to move sand from the shoal during low tides, presently placing sand in the eastern fill are near Ocean Club and the golf course. Once a new bulldozer arrives on site, the sand piles in each fill area will be leveled out to produce a smooth berm. Sand hauling will continue over the next month in a similar fashion. R.B. Baker will place additional sand along the area near Beachwood East and Dunecrest Lane beginning later this week or once the new bulldozer arrives.
January 2, 2015: R.B. Baker resumes work today by harvesting sand from the shoal via the constructed causeway connection. Sand is expected to be placed in the area of Ocean Club for the next several days. A top priority is to locate a replacement bulldozer for the non-operational one. Once a replacement is located, the piles of sand on the beach will be leveled. Each day, construction will take place during the two-and-a-half hours on either side of low tide. No work can occur at high tide. When trucks are operating on the wet sand portion of the beach, visitors should please avoid that area.
December 23, 2014: Baker has stopped working for the day and will break for the holiday week. Work will resume on January 2, 2015. Due to an equipment breakdown, the bulldozer has been non-operational ad has not been able to smooth the piles, so they will have to be there during the break. Baker plans to bring in a new bulldozer once work resumes. The dozer can not be moved at the moment, so it will remain near the high-tide line near the Property Owners Beach House. The wheeled vehicles will be stored at the Citadel Beach House and the remainder of the equipment will be stored off of the beach during the break.
December 19, 2014: R.B. Baker continues to work exclusively off of the shoal. They are placing sand in both fill areas. They will level the piles before leaving for the holiday break from December 24, 2014 to January 1, 2015.
December 16, 2014: Over the past weekend (December 13-14), R.B. Baker established a causeway connecting the beach to the shoal which was offshore of Wild Dunes. Work in the near term will continue by harvesting sand from the shoal around low tide (typically 2-3 hours before and after low tide) and placing the sand in the fill areas. Work will concentrate on the area between the Wild Dunes Property Owners Beach House and the Links golf course this week and into the weekend. Beginning sometime near Sunday, December 18, sand will be placed along the narrower areas of the western fill site near Beachwood East and Dunecrest Lane. No additional harvesting is anticipated in the area between 53rd and 56th Avenue. The beach will be available for public used when the contractor is not working close to high tide. No work will be done between Christmas Eve ad New Years Day.
December 13, 2014: R.B. Baker began working today on building an access pathway connecting the intertidal beach to the shoal which is just offshore. Once the pathway is complete, likely in two to three days, R.B.Baker will begin harvesting sand from the shoal during low tides, when the shoal is above the water. The current work plan is for R.B. Baker to work the area between Beach Club Villas and the Links course through the holiday break. No work is planned to occur between Christmas Day and New Year's Day. As the project progresses, adjustments may be made to the work plan to best utilize the working times and available sand sources. Updates will be posted as soon as they become available.
December 1, 2014: R.B. Baker is working on the East end today and tomorrow and plans to return to working on the West end on Wednesday. Sandbags are still being removed from Beachwood East, which should continue through Thursday. No work is expected over this weekend.
November 25, 2014: As of yesterday evening, the contractor, R.B. Baker, has moved approximately 79,701 cubic yards of sand. Nearly 2,000 loads (approximately 56,600 cubic yards) have been placed along the eastern fill area (Seascape, Ocean Club, and the 18th Hole). Eight Hundred loads (approximately 23,000 cubic yards) have been placed along the western fill area (Beachwood). The recent tides and waves produced significant profile adjustment, where much of the sand placed along the upper beach shifted to lower in the beach profile, resulting in loss of most of the dry sand area in front of Ocean Club. Baker will spend all day today placing sand in that area, and then will split the trucks tomorrow morning to have one placing sand at Ocean Club and one at Beachwood to shore up the dune prior to the holiday break. Tides will be lower as the week progresses and the weather is scheduled to improve, especially over the weekend, so hopefully the fill placed over the next two days will maintain a dry beach until work resumes Monday. The trucks will be kept at the Citadel Beach House during the break. The excavator and dozer will be placed along the access near the Wild Dunes Property Owners Beach House (leaving sufficient room for emergency vehicle access). Coastal Science and Engineering will assess the site on Sunday or Monday to determine what area will be filled when work resumes. Happy Holidays to all.
November 24, 2014: High tides impacted the Ocean Club end of the project. The contractor has moved back to the northeast end of the project to work to repair damage from high tides. Two more days of high tides are expected before they settle down.
November 14, 2014: The project is anticipated to move to the Dunecrest and Beachwood East areas on Monday, November 17. The area between 53rd and Dunecrest will have construction impact.
November 11, 2014: Project work is not scheduled to occur from Thursday, November 27 through Sunday, November 30.
November 10, 2014: As of the end of the day, 22,226 cubic yards (770 truckloads) of sand had been moved from the eastern harvest area to the eastern fill area for an average of 3,175 cubic yards per day. Work is expected to continue in the east area through Friday at minimum.
November 6, 2014: Project work is expected to continue through the weekend in the area of Ocean Club.
November 4, 2014: The project began moving sand this morning in the area between Property Owners Beach House and the 18th hole of the Links Golf Course. Work will continue in this area through the remainder of the week. For the safety of the public, ropes have been installed to separate active construction zones from beach visitors. Beach access is available near the Grand Pavilion or West of Property Owners Beach house. The seawall, installed near Ocean Club, has been completely removed by the responsible parties.
October 28, 2014: City Council approved the change order to R. B. Baker authorizing construction on the 2014 Shoal Management Project. Preparations are being made for an anticipated start date of November 3 and sand movement is expected to begin on November 4th at 7 a.m. Beachgoers will see large equipment and trucks which will be roped off. Areas seaward of the ropes will be inaccesible to the public. For the first week, work is expected to occur in the Eastern area between Wild Dunes Property Owners Beach House and the 18th hole of the Links Golf Course.

2008 PROJECT SUMMARY
The northeastern end of the Isle of Palms endured a severe erosion crisis as a shoal attached to that section of the island. If the acute episode continued unabated, structures could have been threatened. In order to protect the public safety and to ensure that the beaches remained healthy, the City undertook a beach restoration project in the spring and summer of 2008. The South Carolina Department of Health and Environmental Control office of Ocean and Coastal Resource Management (SCDHEC OCRM) issued the City a permit that stipulated "up to 885,000 cubic yards of sand will be dredged from four offshore borrow sites and pumped via hydraulic pipeline to renourish 13,785 linear feet of beach." This project restored the dry sand beach, controlled the erosion and included the removal of all sandbags placed in the erosion area.
The City of Isle of Palms Local Comprehensive Beach Management Plan, including Appendices, was approved by SCDHEC OCRM on April 7, 2008.
As part of the permit requirements for the 2008 project, the City executed a pre-project monitoring in May 2008 and post-project monitorings in October 2008, May 2009, September 2009 (Year 1), May 2010, September 2010 (Year 2) and June 2011 (Year 3). Included in the post-project monitoring are surveys of the beach and borrow areas as well as benthic analysis. Another important part of the post-project monitoring was compaction testing, which determined whether the sand needs to be tilled before the start of turtle nesting season.
Monitoring of the entire seven miles of Isle of Palms beach has been planned for 2012, 2013 and 2014.
2008 PROJECT FREQUENTLY ASKED QUESTIONS
Are there photos of the project?
Click here to view a photo gallery.
When did the project start?
The project began over Memorial Day weekend 2008.
When did the project end?
Project construction was completed in early July 2008.
Where did the project start and end?
The restored beach runs from 53rd Avenue to Dewees Inlet. The project map shows that sand was placed in three major areas called Reach A, Reach B and Reach C. Where the project starts and ends exactly, including where construction occurred on any specific day, depended on several variables including weather conditions and material conditions.
What about the sea turtles that nest on the Isle of Palms?
The City continues to work closely with all appropriate local, state and federal agencies to ensure maximum protection for sea turtles. The permits issued by the agencies allowing construction to occur include clear guidelines to protect sea turtles. Every night and every morning, turtle monitors walked the construction area looking for turtles and their tracks, and if one was found, the appropriate steps were taken to protect the turtle and its nest.
Did the project run all day and night?
Yes. The project did run 24 hours per day and 7 days per week. The goal was to complete the project as soon as possible, so unless inclement weather forced a delay, construction continued all the time. The project was completed several weeks ahead of schedule thereby minimizing disruption to beach goers.
What was construction like?
The City contracted with Weeks Marine to perform the construction. Beach restoration is a large project that involves an off-shore dredger, large pipeline and heavy equipment and trucks. Visitors and residents in close proximity to the project encountered this large equipment and heard the accompanying noise. At night, lights illuminated the beach so construction could continue. These disruptions were temporary as the project moved down the beach.
Was the beach closed?
The restored beach is approximately 9,200 feet long, but only a smaller section of the beach was under active construction on any given day. The section under construction was clearly marked and closed to visitors. The rest of the beach was open as usual. Also, the construction was progressive, meaning it moved along the beach during construction.
Did the project affect boaters?
Boaters needed to be aware that pipeline, marked with buoys, was be submerged in the waters around the project.
What about the sandbags?
As part of construction, all the sandbags were removed from the beach.
What was the beach like when the project was completed?
The project restored a wide, dry sand beach.
