RE: EXEMPTED PROJECT (MINOR) • MAINTENANCE AND REPAIR
(15A NCAC 07K .0103)
PROJECT ADDRESS — Walkway Bridge on Swamp Trail within Carolina Beach State Park
AREA OF ENVIRONMENTAL CONCERN — Coastal Wetlands
Dear Mrs. Lynch:
I have reviewed the information submitted to this office in your inquiry concerning the necessary filing of an application for a
minor development permit under the Coastal Area Management Act. After making a site inspection on August 28, 2009,1 have
determined that the activity you propose is exempt from needing a minor development permit as long as it remains consistent with your
site drawing and materials list submitted by email on October 7, 2009, and meets the conditions specified below. If your plans should
change and your project will no longer meet these conditions, please contact me before proceeding.
MAINTENANCE AND REPAIR • (G.S. 11 3-103(5)(B)(5) and 7K.0209) - Structures may be repaired in a similar manner, size and
location as the original structure. No expansions or additions are permissible. The repairs are limited to 50% of the physical value of
the existing structure and the following specific conditions.
1. The project consists of the repair of the walkway bridge located on Swamp Trail within the Carolina Beach State Park, as
shown on the attached drawing and materials list.
2. The proposed repairs shall be consistent with all other applicable local ordinances and North Carolina Building Code
standards.
3. This exemption applies to maintenance of the existing bridge by repairing the walkway bridge and constructing handrails .
This exemption to CAMA permit requirements does not alleviate the necessity of your obtaining any other State, Federal or Local
authorization and N.C. Building Permits. This exemption expires 90 days from the date of the letter.

Carolina Beach State Parlc Swamp Trail Bridge Replacement
This project will provide a 20' bridge that will be 36" above grade and will replace the
existing bridge. The water flow beneath the current bridge is blocked by debris due to
low clearance. The new bridge will allow water to flow between a Tidal Cypress -Gum
Swamp and a Salt Marsh. Allowing salt water to flow naturally between these two Plant,
communities should act as a deterrent to the rapidly multiplying invasive plant species,
Phragmites.
Project Specifications:
1. The design includes handrails that meet the requirements of the NC
Accessibility Code (NCAC), Section 5.4. The top of both handrails will be
34"-38" above the walking surface. There will be a minimum clearance of
1'/" between the handrail -grasping surface and the adjacent surface. All rails
will have an edge radius of at least 1/8" and be free of sharp edges, splinters,
etc.
2. The walking surface of the bridge will be more than 30" above grade much of
the way_ Guardrails will be included at a height of 46 %" from the top of the
walking surface to the top of the guardrails and will be outside the handrails.
Handrails will be attached to the guardrail structure.
3. To meet the spacing requirements permitted by the NCAC (i.e. 3/8",or 7/16".
spacing between deck boards), 2"x6"x7' deck boards will not be spaced apart
when 'nailed. This will compensate for board drying and shrinkage,
imperfections, and nailing tolerances.
4. The 6"x6" posts will be embedded 4' to help prevent pullout of the posts
resulting from buoyant forces imposed in the unlikely event that the bridge is
submerged.
5. This bridge shall be constructed to support a live load of no more than 4,000
Pounds. It shall be constructed to support ATV off road utility vehicles only
and will not be constructed to support the weight of large tractors, dump
trucks, etc.
6. Carolina Beach State Park will make certain that the work site is
blocked/flagged off so that visitors do not attempt to use the new bridge
before it is completed.
