the proposed "Pelican Point" project, HDI Holdings LLC, we are requesting a minor modification to our existing CAMA permit #20-16 The original srteplan with noted changes, the plans depicting the changes and copy of certified mailing of notification/waiver sheet provided by Division of Coastal Management have been included The proposed changes under this minor modification are highltted in yellow and notated in red on the original The proposed building changes include • The expansion of the footprint of the building by approximately 3' in width through the main body of the building • The building will also be repositioned in the center of the property creating new setbacks from the side property lines of approximately 17' each on the north and south side of the building • The driveway extending along the north side of the building has been eliminated and the new end of pavement line is noted • Moved storm -water storge from under building and into parking area with slight modification to parking layout In addition to the change in the building footprint and setbacks, there have been some minor modifications to the water -dependant structures as well • A separate drawing has been provided (Bulkhead and Pier Layout Schematic) which details these changes • The modifications shown include the reconfigured pier head which was previously long and narrow and vaned in width which is now square in shape • The floating dock has been extended in an "L" shape alongside of the pier head and connecting back to the original floating dock RECEIVED DCM WILMINGTON, NC APR 0 4 2017 • The previously shown wooden walkway running parallel to and behind the bulkhead wall has been eliminated and the wooden walkway to the pier from the pool area has been re- aligned to connect the wood pool deck directly to the pier with no offset as previously shown • The bulkhead wall has also been extended north at an angle to terminate at the adjecent property, this wall was previously shown as "future bulkhead wall" with a dashed line • A new detail has been provided on the engineered Bulkhead and Pier Plan (A/S2 0) showing the option for contractor to place rip -rap at the base of the bulkhead to reduce sheet pile length to 14' • The size of the wood pool deck within the 30' MHWL Setback has been reduced in size to be less than 200 square feet within the setback (187 sq ft ) NOTE The 30' MHWL setback has been confirmed and platted from the basin bulkhead on the adjeacent property (south) Notices of these proposed changes were sent via certified mail with
