He requested that I provide some method or procedure to allow him to continue with his project. As explained in my phone message to you, individual engineered systems designed to accommodate the BUA overages are not allowed. Your only recourse is to modify the permit. The State cannot force you to accommodate his request - that is entirely up to you. There is sufficient unused built - upon area in Magnolia Greens to allocate additional BUA to Mr. Causey's lot (his letter does not indicate exactly how much more he would need), and maintain compliance with the overall low density requirement. However, you may have other plans for that overage amount for future development. , As stated in my phone message, this is entirely up to you. If you decide to proceed, the proper method is to submit a permit modification with new deed restrictions so that the lot can be identified in the permit. As I'm sure this situation will come up again, I will be reviewing any modifications for additional BUA on single family lots to make sure that no pockets of high density are being created. If you have any questions, please do not hesitate to call me at (910) 395-3900.

He indicated yesterday that he had received a voice mail from you indicating that I would be able to install my driveway in the requested manner, which exceeds the 4000 square feet limit of impervious area.

DESIGN NARRATIVE I. GENERAL: The project site 15 located within the Magnolia Greens subdivision within Brunswick County, North Carolina. The area affected by this modification lies entirely within the permitted area of Magnolia Greens (5W8 9701 04). Drainage considerations are to be in accordance with DEM stormwater requirements. The intent of this project 15 to construct a corporate meeting center and additional parking lots at the existing clubhouse facility for the golf course. Stormwater project 5W8 970104 15 a master plan and permit for the Magnolia Greens Plantation. This 15 a low density protect based on built upon area, but 15 considered a "high density Subdivision" due to pockets of higher den5itfe5 and due to curb and gutter collection systems throughout the Magnolia Greens Plantation. To demonstrate that this project 15 indeed low density, a complex BUA tracking chart 15 included on the Stormwater master Plan summarizing the built upon areas for all stormwater projects within Magnolia Greens and projecting built upon area for future projects. It is also the intent of this project to update the Stormwater Master Plan, the application governing this plan, and the master Low Density Supplement. Specifically, all of Section 7 (at the end of the road formerly called Rubra, now named Cherrywood Lane) has been deleted from the plan. The BUA associated with Section 7 was included in the Phase I, Single Family column of the BUA tracking chart. This column has been rev15ed. A patio home community (Patio Homes III, 5W8 991 13G) has been proposed in its place and will be a stand alone stormwater project. A new column has been added to the plan to include Patio Homes III against the overall, projected BUA for the development. Future multi -family section K and M have also been deleted from the BUA tracking chart. Section M has Simply been abandoned (to allow for the additional parking at the clubhouse), while section K has been combined with the East Commercial Area (General Permit 5W8 0001 23) and a revised BUA projected for this Site. Future 51ngle family section D has also been revised. The additional nine holes of golf has dramatically reduced the scope of Section D. The project 15 currently in design, and new projections for BUA have been included in this Master Plan Revision. finally, the column for the Clubhouse, Site has also been revised to include the increased BUA proposed with the new parking and meeting center. As you can See, the overall density for the project (including existing, proposed, and projected built upon area) 15 well below the 30% low density threshold, coming in at an estimated 18.23%. 2. EXISTING SITE: Site topography in the area is relatively flat with slopes typically less than ( I ) one - percent. Vegetation consists primarily of grasses and minor ground cover within the area of the improvements. Subsurface soils are typically a mixture of sands, silty sands and organics. 3. PROPOSED IMPROVEMENTS: Improvements proposed include the construction of 3 new parking lots on the east side of Linkwood Circle at the clubhouse and a new corporate meeting building located north and west of the existing clubhouse facility. 4. STORMWATER TREATMENT CONSIDERATIONS: Infiltration within the golf course will be promoted wherever possible. Runoff from cart paths will flow to the golf course and infiltrate or will flow overland through natural vegetation for a distance not less than 30 feet before commingling with runoff from other areas. This will hold true for that portion of the clubhouse that drains to the golf course and for the proposed building behind the clubhouse. All of the area west of the clubhouse building drains to a large golf course pond that also Serves as supply for the golf irrigation system. The built upon area from the clubhouse draining to the golf course includes approximately half of the clubhouse building, the proposed meeting center building, the clubhouse patio, and an undetermined amount of golf course cart path. The drainage basin for the golf course pond is well below the 30% threshold for low density development, and there is very little chance that runoff from this area will ever reach any surface waters of the State. The golf course pond must be supplemented with several Of five supply wells Just to maintain sufficient water level and volume to supply the irrigation system. The water pumped from the pond is aggressively filtered before use in irrigation to protect the tiny nozzles of the irrigation spray heads. The filters are periodically back washed to maintain efficiency. The balance of the built upon area at the clubhouse site drains to a sub -surface storm drain collection system. The system outlets to a wet detention basin, formerly Permitted under 5W8 970104 for stormwater treatment. The outlet of this pond now flows to another wet detention basin, permitted for treatment under 5W8 990G28 (The Fairway Villas at Magnolia Greens). As stormwater ponds in series 15 not an acceptable form of treatment, the second basin has been designed to treat runoff from all built Upon areas within its drainage area, including all of the area encompassed by the collection system at the clubhouse. The pond at the Fairway Villas 15 considered an offsite treatment facility for the collected stormwater runoff from the clubhouse site. (Note: A permit modification 15 being submitted concurrently with this project to update 5W8 99OG28. An engineer's certification of the treatment pond is included with that submittal.) In addition to the Stormwater Master Plan, a site specific stormwater plan has been generated for the clubhouse Site detailing the impervious area draining to the collection system and, ultimately, to the offsite source. The BUA tracking chart on the site specific plan refers specifically to the offsite source. The clubhouse column in the BUA tracking chart on the Stormwater Master Plan includes all of the impervious area at the clubhouse, including that which drains to the collection system and that which drains to the golf course.
