This package includes the application fee and two copies of: • Two copies of application form FTA 04-16. • Two copies of the USE for the project. • The application fee of $480. Please let the following serve as a brief narrative for the project: The most recent permit for this project was granted on July 20,2007. At that time the flow allocated was 11,200 gpd. The original design was for the project build out which included residences and a clubhouse with a pool. The original permit included 27 three to four bedroom residences and an amenity center/pool complex. The current state of development includes a total of 183 bedrooms. This includes 3 bedrooms allocated for the pool/amenity center. The next phase of development is seeking an additional 117 bedrooms for a total number 200 bedrooms. This yields a flow of 24,040 gpd (200 x 120 = 24,040). The current allocation is for 11,200 gpd so the difference being applied for in this application is 12,840 gpd (24,040—11,200 = 12,840). Please note that this application does not propose any changes to the lift station since it was originally designed for this ultimate flow. The lift station has a stand-by generator in place. If you have any questions please feel free to call me at 910.448.1046. Sincerely, / t/l��l A � Michael C. Gallant, PE gallantmc@yahoo.com tel 910.448.1046 P.O.
