JAMES PLANTATION BRUNSWICK COUNTY, NORTH CAROLINA Project #08142.PE DESIGN NARRATIVE The Reserve Development Company, LLC previously permitted and developed the Club house and recreational areas at the Signature Clubhouse within The Reserve at St. James development. The Signature Clubhouse is located along Fairlawn Boulevard (please see vicinity map on the cover page of the design plans). In order to accommodate future development of the adjacent residential area the owner is proposing an enlarged pond for the previously permitted pond 2. The pond labeled pond #1 is currently constructed and in use for the phase 1 portion of the clubhouse. It is the client's desires to modify the permit and reconstruct Pond 2 to serve the anticipated future developed area, the layout and details of the future development area yet to be determined and the actual construction of that area will be some time in the future. The area for future land use is 24 acres with 60% impervious coverage for the drainage area. The site currently drains to Beaver Dam Creek (SC; SW, HQW) within the Cape Fear River Basin and according to the NRCS Soil Survey of Brunswick County the soil across the site consists of Leon Fine Sand (Lo). The existing ground cover consists of poor brush. Please find that the wet detention pond #2 has been redesigned to serve two drainage areas, the previously permitted Signature Clubhouse recreational area and anticipated future development. Impervious allocation for each area can be found within the design documents and relevant permit applications. All stormwater runoff will be conveyed to the wet detention pond by a storm drainage network where it will be treated and stored per NCDENR and Brunswick County stormwater regulations. An approved erosion control permit exists for the site BRUNS-2005-380 (07/06/05) and will be modified as necessary to include any additional disturbed area but the clubhouse area is under the current erosion permit and will be area to be disturbed and constructed.

The Signature Clubhouse at St James Plantation Express Stormwater Narrative May 2013 Project Narrative: Reserve Development Company is proposing the modification of stormwater permit SW8 081207 approved September 15, 2009. The site is located within The Reserve at St James Plantation off of NC Hwy 211 and will consist of a clubhouse to be constructed in the first phase with the provided future development. Based on the wetland pockets, a regional type pond is the most effective to meet the state and county requirements. Currently a portion of the clubhouse site is constructed, that is permitted for the pond 1 drainage area. The clubhouse site has an erosion control permit and one for the future area will be submitted after a land plan is finalized. The project is within a drainage basin that drains to Beaverdam Creek (SC;SW,HQW). The stormwater will be conveyed through a stormdrainage system and treated in a wet detention pond per high density design criteria. In conjunction with this, they will be designed to meet the Brunswick County Storm Water Ordinance. This project will not have any wetland impacts and all permit applications for the whole development have been submitted to the necessary agency for review and approval. 6Y:_ i t WEMANDS \ 1 w 1 - - .1- \ \ \ WEMANDS \ 1 w 1 - - .1- \ \ \ t cucglc Eanh r .-.� .. i AN Y ti �y � 6 - Goo,(-�Ic earth I .1.

Is the wetland delineation in the vicinity of the proposed regional pond still valid (i.e. less than 5 years old)? We have an approved wetland permit 2. Are any wetland impacts proposed as part of this modification? No wetland impacts 3. Is the existing pond in the location of the proposed regional pond area permitted with the adjacent subdivision project? A portion of the streets appears to drain in that direction. If it is permitted with the adjacent site, that stormwater permit will need to be modified as well. —Only permit that is affected is the clubhouse 4. Has the erosion control plan been modified? — EC permit covers the area for the clubhouse and pond location. Upon final land plan for future area, EC permit will be updated Please let me know.
