The Town of Surf City currently has three beach nourishment projects underway:
1. EMERGENCY BERM/SAND HAUL:
Emergency Berm/Sand Haul Project – The Emergency Berm/Sand Haul project is being completed on the South end of town from Charlotte Avenue to the sand bag revetment near the Bumblebee Tower near the town line. On Feb. 4th Council is set to vote on a budget ordinance amendment to provide a continuous berm for the remainder of the Surf City ocean front properties north of Charlotte Avenue that were previously not identified as imminent critical post Hurricane Florence. Properties within the areas north of Charlotte Avenue that received the emergency berm in Spring 19’ will not see an additional deposit of material as part of the Charlotte Avenue North 2020 project. All sand haul work is being completed by CM Mitchell. Expected completion is mid-April. Homeowners are asked to please remove sand fencing from frontal dune and/or new berm if you are one of the impacted properties Charlotte Ave - North.
April 3 Update: CM Mitchell Contractors have been operating at a slower pace the past few days. This is due to an equipment malfunction at the sand mine site. On Friday, March 27 the sand dredge malfunctioned and it was temporarily repaired. A part has been ordered and should arrive any day. Once the dredge is back in full operational order CM Mitchell trucks will begin to haul at their normal pace. The project is almost 100% complete, this malfunction should not alter the completion of this project. Crews are expected to be completed no later than the end of next week.
Beach Access / Stair Replacement
On Friday, March 20th Mayor Medlin received the letter below regarding beach access-ways and oceanfront access structures.
As you know, the Town of Surf City and the NC Division of Coastal Management have been working together to address beach access walkway concerns with the goal of improving beach access following construction of the FEMA emergency beach berm. Since our staff’s February 19, 2020 public presentation and discussion at the Surf City Welcome Center, we have reviewed and considered many options presented by Town officials as well as private property owners. We have also conducted several site visits, and have observed continuing erosion at the base of the emergency berm following construction.
As we’ve discussed, the FEMA emergency berm does not meet the Coastal Resources Commission’s definition of a frontal dune (15A NCAC 07H.0305(a)(4) and .0308(c)), and therefore DCM cannot authorize structural accessways across the berm. After careful consideration, the NC Division of Coastal Management offers the following guidance for beach accessways over the FEMA emergency beach berm that extends to the Surf City Town Limits:
- Limited stairs may be added to damaged structural accessways that are broken off above ground level in order to allow access to the beach, but the stairs must be oriented parallel to the beach, cannot extend toward the water, and shall not terminate beyond the toe of the escarpment or below the normal high tide line, whichever is farther landward. Any proposed addition of stairs or other structural components requires a case-by-case review by DCM staff.
- Other acceptable construction materials for accessways on the FEMA berm shall be limited to temporary slatted, wooden or composite (plastic or rubber) roll-out matting. These temporary beach walkways may be fastened or attached to any existing structures; however, no new pilings, posts or other subsurface anchors shall be used. Any materials used for this purpose shall be placed on the face of the berm and shall not terminate beyond the toe of the escarpment or below the normal high tide line, whichever is farther landward.
- All other proposals for alternative beach access walkways will be evaluated on a case-by-case basis; however, the roll-out matting may be used without additional approval provided the temporary structures do not impede emergency access along the beach or restrict the public’s ability to utilize the beach. Please note that removal or modifications to these structures may become necessary if erosion continues.
We thank you for your patience concerning this matter and ask that you please contact me or Tara MacPherson, DCM Wilmington District Manager, if you have any additional questions, comments or concerns.

2. FEDERAL BEACH NOURISHMENT UPDATE 1/13/2020:
We have received *GREAT NEWS ON OUR BEACH NOURISHMENT PROJECTS* today! The U.S. Army Corps of Engineers announced today they will be funding a flood and storm damage reduction project (Beach Nourishment Project) for our town. Mr. R. D. James, assistant secretary of the Army of Civil Works stated: “The supplemental funding allocated to these projects will help to ‘move dirt’ and reduce the flood risk to these communities from storms in the future.”
Federal/USACE Project - Surf City and North Topsail Beach will be receiving $237 million for federal beach nourishment. So, in addition to our privately funded beach nourishment project, we have received the great news that Surf City has been approved for a FEDERALLY FUNDED BEACH NOURISHMENT PROJECT. We have been working toward obtaining this funding for a significant amount of time and with persistence have now been approved federally. Many people have worked on getting this project approved. We have had local citizens, town government, Shoreline Protection Committee, and State & Federal Legislatures all working toward this goal. We are thrilled to have this highly sought after project coming to our beach. As we establish timelines surrounding this project we will update you as we can. We will be making decisions around the timeline and how to best coordinate this with our private project to maximize the benefit for our town in the coming weeks.
Perpetual beach easements are expected to be mailed out between April and May 2020. Questions regarding beach easements may be addressed to Stephanie Hobbs at 910-328-4131 x 106 or email@example.com.
3. PRIVATE BEACH NOURISHMENT PROJECT:
The Private Nourishment Project is awaiting final permit approvals within the coming weeks. Once permits are in hand TI Coastal, the Town’s coastal engineer, will assist the Town in going out to bid for contracts based on the scope of work provided by the engineer. The tentative start date is November 2020. The reason for the delay in start is due to environmental constraints in being the sea turtle moratorium that runs from April through November. This project will utilize material from the dredging of Banks Channel by pumping sand to the beach, which will provide additional depth and re-sloping of the frontal dune.This project will advance your shoreline to 145 feet wide with a 1 on 20 slope.
Post Florence Imminent Critical Lot Analysis Explanation:
“Imminently Threatened” – This is a NCDCM (CAMA) term that means that the dune escarpment (the “drop off”) is within 20 feet of the foundation of the house.
“Hyper-Critical”- This is a term I used to describe area where infrastructure or house foundations were at immediate risk of being undermined by another erosion event. In most cases these are areas where:
- The house or infrastructure meets the definition of imminently threatened.
- The infrastructure is installed below elevation 8’ NAVD88.
- Ground elevation for house is above elevation 14’ NAVD88.
Our process in determining the sand placement area is as follows:
First, using the Post-Florence beach surveys which went from the road to 3,000 feet offshore, we determined the +14’ and +8’ contours. These contours define the seaward face of the dune, the angle of the drop off, and where the dune had been completely over-washed. We then overlaid these contours onto post storm aerial photography to determine the distance of the escarpment from the houses. Next, we determined how much sand would be required to complete the berm at the north end to protect the water sewer and road infrastructure. This took approximately 60,000 of the 160,000 cubic yards of sand that we believe the Town can obtain for the $5M budget.
Next we looked at proximity of the escarpment to the houses based on the 14’ contour or lack thereof. We prioritized houses in blocks of 4 or more, as putting sand on less than a 200ft strip would result in too rapid of erosion. Some house that were substantially forward of their neighbors were eliminated based on this protocol.
Lastly we looked at ground elevation under the houses and prioritized houses with higher escarpments. This was important. House pilings are typically driven 8 feet into the ground. Thus if the ground elevation is 14’, then the bottom of the pilings is at elevation 6’ NAVD88. Dune erosion typically takes the elevation down to about elevation 6’. Thus a house built a house built at elevation 14’ or above would totally collapse with only 10 more feet of dune erosion, while a house built on ground elevation 8’ or less can survive a wash through.
All of these things were taken into account in order to protect the most sensitive areas first and the most areas possible with the 100,000 cubic yards available. All of these decisions were very tough as we feel the entire beach needs restoration. We have done our best to look out for the Town as a whole, strictly using scientific and mathematic principles. While some homeowners may disagree with the outcome of this process, it is the only ethical way to do complete this difficult task under the current constraints..
