Included is Bald Head Island Ltd Planning and Permits Check # 1543 for $100 for the renewal. Deep Point is still an important part of the Bald Head Island Limited, LLC ongoing development. As the mainland transportation terminal for the Bald Head Island Ferry, parking facility for almost 3000 vehicles, and the home to an 86 slip recreational "Clean Marina", Deep Point may seem to be pretty complete. However, we still have plans (already in the 91-96 CAMA Permit) for a future Administration Building, Restaurant, Hotel, Marina -front Shops and more parking. It will be several more years before Deep Point is "complete". Thanks for your always kind assistance in this manner. Bruce Marek, P.E.

Secretary RECEIVED NOV 16 2016 DCM- MHD CITY This is with reference to your request to modify State Permit #91-96, acting as agent for Bald Head Island Limited, LLC. The permit was issued on June 3, 1996 and expires on November 15, 2016. The action proposed in your submittal, as submitted in your March 2, 2015 request, is to modify the dimensions of the ferry maintenance dock. The dock was originally authorized at 95' in length by 8' in width. The modified dock would include a 16' in length by 10' in width floating ramp landing platform connecting to a 70' in length by 6.25' in width dock. Ferry access dock steps leading to a cantilevered platform would be constructed approximately midway along the dock. Twelve dolphin pilings, each consisting of 4 pilings, are also proposed along the dock. In reviewing the information provided, the Division of Coastal Management has determined that the proposed action is consistent with existing State rules and regulations and is in keeping with the original purpose and intent of the permit. This Letter of Refinement authorizes the modification of State Permit #91-96, as described in your letter dated March 12, 2015 and plan labeled "Sheet: Deep Point Marina Floating Maintenance Dock", dated March 12, 2015. All permit conditions remain in effect. Please note this refinement does not authorize any work not expressly described above, nor does it eliminate the need to obtain any other additional state, federal or local permits, approvals or authorizations that may be required. By copy of this letter we are also notifying the U. S. Army Corps of Engineers and the NC Division of Energy, Minerals & Land Resources of our action. If you have any questions concerning the above or if I can be of any other assistance, please advise.
