The site is currently vacant. The site is immediately adjacent to the Intracoastal Waterway (SA) in the Cape Fear Basin. Existing site topography is generally flat/gently sloping (0 -5%) towards the western boundary of the tract (adjacent to Intracoastal Waterway). Soils are fine to coarse sand. Topography suggests that precipitation currently infiltrates into the sandy soils or sheet flows into adjacent wetland areas. On the basis of entire tract, development activities are Low Density (16.73%). However, 4.46 acres of the total 5.98 acres are wetland. Excluding wetland areas, the proposed development activities are high density (BUA=65.80%), therefore, stormwater treatment facilities are required. Because the site is located adjacent to class SA waters, an infiltration system is required. Because of site topography, groundwater conditions, and setback requirements it is necessary to collect first 1.5" of stormwater in a subsurface storage system constructed from a series of 60" diameter HDPE pipe sections and 36" manifold. Collected storwmater will be pumped from the storage system to an upgradient infiltration bed located near the front of the site. Proposed impervious areas are as follows: Site Offsite Total Buildings 22,392 sf -0- 22,392 sf Streets 11,762 sf -0- 11, 762 sf Parking 7,155 sf -0- 7,155 sf Sidewalks 2,259 sf -0- 2,259 sf Other -0- -0- -0- Reserve for Future -0- -0- -0- Total 43,568 sf -0- sf 43,568 sf Proposed grading activities will be limited to installation of building pads, roadways, and d riveways. Proposed erosion sedimentation control measures include silt fence and four temporary sediment storage basins. Temporary diversion ditches are proposed to divert all runoff toward the proposed basins. The proposed basins contain adequate storage to accommodate sediment generated from the project area based on 1,800 CFlacre requirements. _C_wstal Coast Engineering, PA 3817-3 Freedom Way Hubert, N.C. 28539 Tel: (910) 325-0006 Fax: (910) 325-0060 Email; Mstalcoasteng@bizec.rr.com October 15, 2005 Mr. Paul T.

The site is currently vacant. The site is immediately adjacent to the Intracoastal Waterway (SA) in the Cape Fear Basin. Existing site topography is generally flat/gently sloping (0 -5%) towards -the western boundary of the tract (adjacent to Intracoastal Waterway). Soils are fine to coarse sand. Topography suggests that precipitation currently infiltrates into the sandy soils or sheet flows into adjacent wetland areas. On the basis of entire tract, development activities are Low Density (16.73%). However, 4.46 acres of the total 5.98 acres are wetland. Excluding wetland areas, the proposed development activities are high density (BUA=65.80%), therefore, stormwater treatment facilities are required. Because the site is located adjacent to class SA waters, an infiltration system is required. Because of site topography, groundwater conditions, and setback requirements it is necessary to collect first 1.5" of stormwater in a subsurface storage system constructed from a series of 60 diameter HDPE pipe sections and 36" manifold. Collected storwmater will be pumped from the storage system to an upgradient infiltration bed located near the front of the site_ Proposed impervious areas are as follows: Site Offsite Total Buildings 22,392 sf -0- 22,392 sf Streets 11,762 sf -0- 11,762 sf Parking 7,156 sf -0- 7,155 sf Sidewalks 2,259 sf -0- 2,259 sf Other -0- -0- -0- Reserve for Future -0- -0- -0- Total 43,568 sf -0- sf 43,568 sf Proposed grading activities will be limited to installation of building pads, roadways, and driveways.

McCallum PO Box 2671 Surf City, NC 28445 Subject: Request for Stormwater Management Permit Application Live Oaks at Topsail Stormwater Project No. SW8 050841 Pender County Dear Ms. McCallum: On August 3, 2005, the Wilmington Regional Office received a copy of a Letter of Receipt for an Erosion Control Plan Express Review for the subject project. The North Carolina Administrative Code requires any project that must receive either Sedimentation and Erosion Control Plan approval and/or a CAMA Major permit to apply for and receive a Stormwater Management Permit by the Division of Water Quality. Any construction on the subject site, prior to receipt of the required permit, will constitute a violation of 15A NCAC 2H.1000 and may result in appropriate enforcement action by this Office. Either a Stormwater Permit Application Package including 2 sets of plans, completed application form, fee, and supporting documentation, or a written response regarding the status of this project and the expected submittal date must be received in this Office no later than October 6. 2005. Failure to respond to this request may result in the initiation of enforcement action, and construction may experience a subsequent delay. The NPDES 010000 Federal Stormwater Permit that accompanies the Erosion Control Plan approval letter must NOT be considered the Coastal Stormwater Management Permit, which will be signed by -the Water Quality Supervisor. Please reference the Project Number above on all correspondence. If you have any questions, please call me at (910)-796-7215.

The Act requires that all persons disturbing an area of one or more acres of land must obtain approval of a soil erosion control plan prior to the commencement of the land -disturbing activity (G.S. 113A-54(d) (4)). The review period for an express review is three days of receipt of a complete plan. if additional information is requested, it must be submitted within five working days of receipt. Commencement or continuation of a Land -disturbing activity under the jurisdiction of this Act prior to the approval of an erosion and sediment control plan is a violation of the Act. We have performed a preliminary review of your submitted plan and have determined that additional information will be necessary before a final review can be completed. Enclosed is a checklist of items that must be submitted before we can complete the review process. Failure to provide the additional information may result in disapproval of your plan. The approval of an erosion and sediment control plan is conditioned on the applicant's compliance with Federal and State water quality laws, regulations and rules. If you have questions please do not hesitate to contact this office. Your cooperation in this matter is appreciated and we look forward to working with you on this project. Sincerely, Carol N.
