Dune Doctors Quote
I was talking to the Dune Doctors and as it turns out they spoke to the Retreat about doing some
work for us after IVAN.
Below is a current proposal from the dune doctors that I asked them to provide before our annual meeting so the board could perhaps revisit this issue.
Keep in mind that this quote is in addittion to the cost of any SAND that the board feels we may need to purchase and put out prior to planting and dune fencing.
Alys Beach choose to double up on the plantings at the toe/base of their dunes instead
of using the Dune Fencing option for aesthetic reasons.

Re: DUNE RESTORATION PROPOSAL FOR THE RETREAT
I am pleased to submit for your review the following proposal. Included is the summary and detail of the work recommended to optimize the level of protection on the property.
Sand Fence addition:
We strongly advise installing sand fence at the toe of the created dune according to DEP (Department of Environmental Protection) standards. It provides the following multiple benefits:
- Helps trap wind driven sand,
- Limits foot traffic over newly planted areas, and
- Reduces the wave’s impact on the dune by redirecting
their path as they come ashore (when installed properly).
Based on the property being approximately 3,000 feet wide and placing 10’ sections of sand fence 9’ apart, you will need 3,340 feet of sand fencing added according to DEP standards at the appropriate angle with the shoreline, in an East-West row South of the newly created dune area.
Installation of Sand fencing
- 3,340 feet of 4’ sand fencing @ $ 4.45 per linear foot = $14,863.00
Native Coastal Vegetation:
To stabilize the dune, limit wind erosion, landscape your beach environment and increase the overall level of protection, we strongly advise to cover any bare surface with native vegetation. Assuming that after sand addition the slope is 30 feet, the total bare surface in need of vegetation will be 90,000 square feet (3,000’ EW by 30’ NS). This measurement needs to be confirmed after sand addition. Our advice to obtain the best stabilization is to install 4” containers of mature grasses at 2’ on center. In addition to stopping wind driven sand, the grasses grow roots 10-15’ deep in the core of the dune in all directions creating a dense net that helps reduce possible erosion. Installing grasses 2’ on center, you will need 22,500 grasses. For adequate coverage and to hold the surface sand, we strongly recommend also planting an additional 10% of that amount in ground covers.
Installation of the plants:
- 18,000 Sea Oats 4” @ $ 3.15 each installed = $ 56,700.00
- 4,500 Panic grasses 4” @ $ 3.15 each installed = $ 14,175.00
- 563 Seashore Elder 4” @ $ 3.45 each installed = $ 1,942.35
- 563 Sea purslane 4” @ $ 3.45 each installed = $ 1,942.35
- 563 Red morning glories 4” @ $ 3.45 each installed = $ 1,942.35
- 563 White morning glories 4” @ $ 3.45 each installed = $ 1,942.35
The cost for this planting option is: $ 78,644.40
The total cost for both options $ 93,507.40
All our plant installations come with a 90 day / 90% survival guaranty.
This estimate includes the following:
10 signs (stating: please stay off the dunes),
a roping of the area (removable if and when desired after establishment of the plants), and
the use of slow release fertilizer and moisture retaining gel to help the establishment of the plants.
Watering events: To help the plants fast establishment, we water them right after installation. If there is a prolonged drought in the first 2 to 3 months after installation and if the plants show some water stresses, we will recommend a watering event with a sprinkler once a week. As long as it rains every 2 to 3 weeks there is no need for watering, since we install the plants with a biodegradable water retention gel. We do not recommend the installation of an irrigation system since established drought tolerant, native plants do not require watering.
Upon your approval, we shall prepare a letter of agreement and will request with its signature a 30% down payment for the nursery to have the plants prepared specifically for your project. Availability will determine the amounts of the different species and plant sizes at that time.
Please feel free to call Dune Doctors at (850) 939-7737. We will be more than happy to answer any questions you may have. We hope to help you enjoy the pleasure and beauty of a native, maintenance free landscape in the near future.
Sincerely,
