Fla. Admin. Code R. 62B-56.030
(1) The Department shall issue a permit for a reconstructed dune after it determines the applicant meets the following conditions:
(a) The proposed reconstructed dune must provide for the protection of an existing vulnerable structure or a structure that is upland of a beach-dune system that has experienced significant beach erosion.
(ii) Application of the SBEACH (Storm-induced BEAch CHange), a numerical simulation model for predicting dune erosion or other similar models recognized by the coastal engineering profession, using the storm surge elevations of a 25-year storm event, as determined by the Department and provided in the above referenced report entitled “Erosion Due to High Frequency Storm Events.”
b. Geotechnical analysis: The applicant may provide the Department an appropriate geotechnical analysis demonstrating that the major structure’s foundation will be subject to damage from a frequent coastal storm.
c. Adjacent structure vulnerability test: The applicant may demonstrate that its major structure or public infrastructure is in close proximity to a vulnerable major structure or public infrastructure and the neighboring property’s proposed reconstructed dune would cause the applicant’s major structure or public infrastructure to become vulnerable. The demonstration shall be provided by a professional engineer and must be based on the results of numerical modeling and engineering analysis that clearly demonstrate to the Department that the proposed reconstructed dune would cause the applicant’s adjacent major structure or public infrastructure to become vulnerable.
d. Site specific vulnerability analysis: The applicant can demonstrate to the Department, through engineering analysis, that another site specific circumstance exists which makes the structure to be protected vulnerable as defined in subsection 62B-56.020(49), F.A.C.
2. If vulnerability cannot be established then the proposed reconstructed dune shall protect an existing major structure or public infrastructure located seaward of the Coastal Construction Control Line (CCCL) that is upland of a beach-dune system that has experienced significant beach erosion from a frequent coastal storm. The applicant may provide the Department for consideration an analysis certified by a professional engineer licensed in the State of Florida demonstrating that the beach-dune system has experienced significant beach erosion. The analysis and supporting data shall be based upon a detailed assessment of the impact of storm events along the subject shoreline. The applicant may provide the following types of quantitative data and analyses for consideration by the Department: beach and offshore profiles, upland topography, nearshore and offshore bathymetry, historical shoreline position changes, storm tide frequency, beach and dune erosion, the effectiveness of previous or existing sand placement efforts in preventing a recurrence of significant beach erosion, post storm assessments of the beach and dune systems, and similar coastal scientific data necessary to demonstrate significant beach erosion. In the event a beach-dune system does not currently experience significant beach erosion, but sand has been placed at the site within five years of the Department’s receipt of a permit application for a reconstructed dune under this rule, then the requirements of this paragraph are met provided that:
a. The sand placement was designed solely for that portion of the beach-dune system that is landward of the shoreline that existed at the time of commencement of the sand placement; and,
b. The beach-dune system experienced significant beach erosion immediately prior to the commencement of the sand placement.
3. Alternatively, if the applicant would otherwise meet the requirements of subparagraph 62B-56.030(1)(a)1. or 62B-56.030(1)(a)2., F.A.C., but the existing major structure or public infrastructure to be protected is not located seaward of the CCCL, the applicant may provide engineering data that shows the existing major structure or public infrastructure in need of protection will be impacted by the storm surge with dynamic wave setup of a one-hundred-year storm or the anticipated erosion of a one-hundred-year storm.
1. Vulnerability shall be certified by a professional engineer licensed in the State of Florida through one of the following methods:
a. Frequent coastal storm vulnerability test using:
(b) Siting and design requirements:
1. The reconstructed dune shall be sited as far landward as practicable, balancing the need to minimize excavation of the beach-dune system, impacts to nesting marine turtles and other nesting state or federally threatened or endangered species, and impacts to adjacent properties.
2. The reconstructed dune shall be sited in a sustainable location so that the core of the reconstructed dune is located no farther seaward than the frontal dune that existed prior to recent storm events or that would naturally develop under similar shoreline locations and conditions, whichever is farther landward.
3. The reconstructed dune core shall be designed, sited, and placed at an elevation so that the dune core is continuously covered with a minimum of three feet of native or beach-quality sand and shall be stabilized with native beach-dune vegetation.
4. The reconstructed dune core shall be designed, sited and elevated to minimize interference with movement of sediment along the beach.
5. The reconstructed dune shall be designed to facilitate easy removal of the geotextile containers.
6. The reconstructed dune shall be designed as a frontal dune having similar crest elevations, side slopes, configuration and continuity to the frontal dune that existed prior to recent storm events or that would occur under similar shoreline locations and conditions.
7. The proposed reconstructed dune shall not result in removal or disturbance of sandy soils of the beach-dune system to such a degree that a significant adverse impact to the beach-dune system would result from either reducing the existing ability of the system to resist erosion during a storm or lowering existing levels of storm protection to upland properties and structures.
8. The proposed reconstructed dune shall minimize impacts to adjacent properties.
9. The proposed reconstructed dune shall not cause an increase in structure-induced scour of such magnitude during a storm that the structure-induced scour would result in a significant adverse impact.
10. The proposed reconstructed dune shall be sited and constructed in a manner to minimize removal or destruction of native vegetation.
11. The proposed reconstructed dune shall not direct discharges of fluids that would result in significant adverse impact.
12. The proposed reconstructed dune shall not cause a significant adverse impact to nesting state or federally threatened or endangered species, and nesting marine turtles; and,
13. The proposed reconstructed dune shall not interfere with public access as defined in section 161.021, F.S.
(e) In considering project impacts to native beach-dune vegetation, the Department shall evaluate the following:
1. Type and extent of native beach-dune vegetation.
2. The degree and extent of disturbance by invasive nuisance species.
3. The degree and extent of disturbance by other construction activities; and,
4. The protection afforded by natural plant communities.
