As you know, the Town of Surf City has been working on a nourishment project to place sand on the beach from Banks Channel all along the Surf City oceanfront. This project will advance your shoreline to 150 feet wide with a 1 on 20 slope.
We plan to begin construction spring of 2020. However, prior to construction, the Town needs your approval to deposit sand and perform other work associated with beach nourishment on your property. The property on which the Town will need to work lies waterward of your frontal dune. This area is specifically described on the enclosed easement. Please be aware that this is not a perpetual easement; the Town only request the easement rights through 2048.
You will not lose land or access rights when you sign the easement. We are simply asking for your approval to deposit sand and work on a specific area of your property. All owners having an interest in the property must sign an easement.
Please return the easement with notarized signatures by January 7, 2019 to:

On January 18, 2019 the Surf City Town Council hosted a beach nourishment work shop with TI Coastal LLC. The Council voted to proceed with the placement of sand berms in imminent critical areas. These areas will be identified specifically by TI Coastal in the coming days. If you are a private property owner who wishes to purchase sand for your berm please contact Town Hall at 910-328-4131 or firstname.lastname@example.org. This process will go up for bid acceptance at the March Council meeting. It is at that time the Town should know the exact cost per cubic yard of sand if you are wishing to purchase sand. Sand should being being placed back on the berms in late March to early April. The council voted to still proceed with the private nourishment project with TI Coastal slated to being in 2020.
February 5, 2019: TI Coastal has identified the imminent critical lots in Surf City, they are highlighted in green. Those lots that are not identified as imminent critical do have a choice to purchase sand for their lots. The design for is roughly 14 cubic yards per linear foots. For those property owners who plan to purchase sand the Town needs a commitment in writing (email) no later than Monday, February 11th at noon. The Town will be collecting payment prior to the sand placement and payment in full is due Thursday, February 28th. Dune replacement is expected to begin no later than mid-March.
Sand Cost Approximate Estimates:
Lot Size 50' $28,000
Lot Size 75' $42,000
Lot Size 100' $56,000
This would be a cost estimate on pushing out the dune line roughly 20-25 feet and 8-10 feet above the beach.
FEMA 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..
