As you are aware,the new wall that was installed has failed or is failing in several locations. In the first modification, Phase I, we cut out the existing, non-functioning weep holes to relieve hydrostatic pressure behind the wall. The sand backfill and water drained out with virtually no turbidity. A turbidity curtain had been installed but wasn't necessary. In this modification, Phase II, we are proposing to cut out the remaining weep holes in the access channel that weren't cut out in Phase I. Due to the success of Phase I and the lack of turbidity, we don't believe that a turbidity curtain is necessary, but will keep one on site for use if needed. As in Phase I, cutting out the weep holes will help to relieve the hydrostatic pressure behind the channel wall. The rest of Phase II of the project is to remove any remaining sand from between the new and old wall in the basin and in the access channel. The areas highlighted in green on the attached drawing are areas where the wall has failed or is failing. We are proposing to remove these sections in order to determine what material can be salvaged and reused. The new wall will be rebuilt in the same location. A new lower waler with king piles is to be installed to add additional structural support. The existing deadmen anchors will then be reattached through the king pile. Jet filters are to be installed in the existing weep holes along with the addition of more jet filters to prevent any future hydrostatic loading. The void area in between the old wall and new wall will then be backfilled with a clean gravel along with a small top layer of soil to allow for ground cover. The remaining sections of the bulkhead, highlighted in pink will, not have to be removed or replaced. However, they will have an upper new water attached and king piles installed,so that the existing deadmen can be properly aligned and attached. Jet filters will also be installed in existing weep holes along with the addition of more jet filters. The void area in between the walls is then to be backfilled with clean gravel and a small top layer as in the other sections. Phase II modification completes the repair and replacement of the existing new failing bulkhead. The finished product will be a secure, sealed wall that will allow any hydrostatic pressure to properly drain and will protect the owners property for many years to come. As always,feel free to call me on my cell anytime 470-6610 if you have any questions or need anything further.

WilsonG-Q`J District Manager, Wilmington DATE: December 28, 2012 SUBJECT: Permit Modification and Renewal Request CAMA Major Permit No. 160-05 Inlet Point Harbor BOA c/o Ann Bowman New Hanover County Mr. Michael Conard with Carolina Marine Construction, Inc. and acting agent for Inlet Point Harbor BOA, is requesting a minor modification and renewal of State Permit No. 160-05. State Permit No. 160-05 was originally issued to Inlet Point Harbor BOA c/o Ann Bowman on October 21, 2005 for maintenance excavation of an existing community boat basin and access channel, adjacent to the AIWW, Myrtle Grove Sound, in New Hanover County. Following Hurricane Ophelia in 2005, State Permit No. 160-05 was modified on June 28, 2006 for the replacement of the existing, deteriorating wooden bulkhead located within the Inlet Point Harbor BOA basin and access channel. Approximately 2,800 linear feet of a new composite bulkhead was installed at an average of approximately 2 feet to 5 feet waterward of the existing wooden bulkhead. State Permit No. 160-05 was then modified on January 23, 2012 to remove/cut the filter cloth at the location of the weep holes of the new composite bulkhead, aforementioned, which would relieve the hydrostatic pressure landward of the new composite bulkhead to prevent future failure. The authorized work was based on the recommendations from Mr. Mark Weiss, P.E., Project Engineer with Criser Troutman Tanner Consulting Engineers, and representing the Inlet Point Harbor BOA. Mr. Weiss indicated that this procedure served to temporarily alleviate the earth and hydrostatic loads and assist to mitigate future catastrophic failures of the new composite bulkhead until a permanent engineered solution can be designed and implemented. According to Mr. Weiss' report, this would result in the loss of fill material from the space between the new composite bulkhead and the existing old wooden bulkhead into the upland boat basin and access channel in the amount of approximately 450 to 1,200 cubic yards. Once the material was drained 3/8" plywood was installed over the existing weep holes, which were cut into the old wooden bulkhead to allow for the installation of the existing tie-back anchor system for the composite bulkhead. This was done to prevent additional loss of material behind the existing wooden bulkhead. The plywood installed over the two existing bulkheads was done during the process to cover the void between the bulkheads for safety purposes. 127 Cardinal Drive Ext.,Wilmington,NC 28405 One Phone:910-796-72151 FAX:910-395-3964 Internet:www,nccoastalmanagement.net NorthC ja'�rofiina An Equal Opportunity 1 Affirmative Action Employer Naturally Inlet Point Harbor BOA State Permit No. 160-05 Modification Request (Phase II) Page 2 A turbidity curtain was also installed at the location of the terminal end of the access channel at the point of the entrance of the boat basin prior to the authorized procedure to reduce the amount of material from escaping the project area; however, it was observed that very little turbidity was present within the basin and access channel during the maintenance work. The work describe above will also be known as Phase I in the authorized initial work to address the hydrostatic pressure on the existing bulkhead. Mr. Conard is now requesting as Phase II to allow for the removal of sections of the existing bulkhead within the basin, which were included in Phase I, to determine if the material can be salvaged and reused. The replacement of these sections would be in the same location, however, new lower whalers with king piles would be installed to provide additional structural support. The existing deadmen anchors would then be reattached through the king piles and jet-filters would be installed to prevent future hydrostatic loading. Once complete, the void between the new bulkhead and the timber bulkhead would be filled with clean gravel along with a top layer of soil for ground coverage. Based on the success of Phase I, Mr. Conard requests to allow cutting weep holes in the remaining access channel bulkhead, which weren't included in Phase I. Further, due to the success of Phase I and the lack of turbidity observed during the process, the turbidity curtain would not be installed unless determined to be necessary. If deemed necessary, the turbidity curtain would be installed along the entrance to the boat basin, and at the entrance to the access channel to the AIWW. The remaining sections of new composite bulkhead with the basin and access channel, which do not have to be removed, would be reinforced with new upper whalers with attached king piles so existing deadmen can be properly aligned and attached. These sections would also include the installation of jet filters, gravel and soil as described above. State Permit No. 160-05 is also due to expire on December 31, 2012. Mr. Conard requests renewal of State Permit No. 160-05 to accomplish the work as described above and also retaining the Maintenance-5 Dredging Clause for the ability to maintain the community access channel and basin. The agent has submitted checks (ck. # 7938 and #7957) in the total amount of $200.00 for the modification and renewal request. This office has no objection to the proposal.
