§ 127-15. Erosion protection structures.

The following requirements shall apply to the construction, modification or restoration of erosion protection structures:

A. 

The construction, modification or restoration of erosion protection structures must:

(1) 

Not be likely to cause a measurable increase in erosion at the development site or at other locations.

(2) 

Minimize and, if possible, prevent adverse effects upon natural protective features, existing erosion protection structures and natural resources such as significant fish and wildlife habitats.

B. 

All erosion protection structures must be designed and constructed according to generally accepted engineering principles which have demonstrated success or, where sufficient data is not currently available, a likelihood of success in controlling long-term erosion. The protective measures must have a reasonable probability of controlling erosion on the immediate site for at least 30 years.

C. 

All materials used in such structures must be durable and capable of withstanding inundation, wave impacts, weathering and other effects of storm conditions for a minimum of 30 years. Individual component materials may have a working life of less than 30 years only when a maintenance program ensures that they will be regularly maintained and replaced as necessary to attain the required 30 years of erosion protection.

D. 

A long-term maintenance program must be included with every permit application of construction, modification or restoration of an erosion protection structure. The maintenance program must include specifications for normal maintenance of degradable materials. To assure compliance with the proposed maintenance programs, a bond may be required.
