Below is a response to each of your concerns. Indicate all stream impacts including all fill slopes, dissipaters, and bank stabilization on the site plan. One temporary stream impact (Span # 1) is labeled on the revised plan view of the site plan. The impact is also shown on Cross Section #1. Because it is an open cut line installation, no fill slopes, dissipaters, or bank stabilization will be used. Silt fences will be used to minimize erosion into the stream and the area will be returned to pre-construction grades. 2. Indicate all isolated ornon-isolated wetlands, streams, or other waters of the State as overlays on the site plan. All wetlands and streams are now shown on the site plan. The wetlands are based on surveyed information, but stream locations are approximate and are based on LMG observations (see stream forms). 3. Locate arty planned sewer lines as overlays on the site plan. Sewer lines will be located within road rights-of--way, except as shown on the revised site plan. It has recently been determined that two additional wetland crossings outside of the bridge locations will be needed. These crossings will be directionally bored as shown on the site plan and insets 5 and 6. 4. Proposed "Wetland Span # 1 " on the plan sheet labeled "Overall Wetland Impact"appears to be a stub road that ends abruptly. The DWQ cannot permit impacts for "roads to nowhere ". Explaifz why this impact is necessary and provide details on the future development to where "Wetland Span # 1 " is pointed. Wetland Span # 1 will provide access to an amenity center located within Phase 2. The site plan has been revised to show the location of the amenity center. www.lmgroup.net • info@Imgroup.net • Phone: 910.452.0001 Fax: 910.452.0060 3805 Wrightsville Ave., Suite 15, Wilmington, NC 28403 • P.O. Box 2522, Wilmington, NC 28402 5. Provide detailed engineering drawings describing how utility lines will be installed at the wetland impact sites listing the depth of placement. Please see enclosed figures. 6. Provide a letter of concurrence from the Town of Shallotte for the placement of the utility lines outside of the 10 foot easement or stating where the utility lines should be placed within the easement. With regards to the NCDENR Notice of Violation, the developer had portions of the sanitary sewer force main installed prior to obtaining the State permit. No sewer flow entered the installed pipe, nor was the pipe ever connected to any existing sewer. It is basically a buried line serving no current purpose. The NCDENR sewer permit has since been issued for the sewer in question. At no time did the installed sewer line disturb wetlands. 7. Explain what is meant by "10 foot utility and sidewalk easement" found on the plan sheets for wetland spans 1 and 2. Sidewalks cannot be counted as temporary impacts. The 10 foot easement is for utilities only. This language has been revised. 8. You do not appear to have avoided and minimized to the greatest extent practicable. Please explain why the utility impacts cannot be avoided through the use of some sort of directional boring to eliminate wetland impacts. The applicant evaluated the possibility of directionally boring utilities under all wetland/stream crossings. However, costs were too great, especially when taking into account that they are already incurring the cost of several bridges to avoid permanent impacts. In addition, two utility crossings will be directionally bored to further minimize impacts (Insets 5 and 6). I hope this response adequately addresses all of your comments. Please contact me if you have any questions or need any additional information. Thank you for your assistance with this project. Sincerely, ~. ~= ~~,~ Kim Williams Wetland Scientist Encl.

Box 1890 Wilmington, NC 28402 RE: Additional Information for San Rio Ocean and River Club: Phases 2 and 3 Brunswick County, NC DWQ Project # 07 1730; Action ID# 200600440 Dear Kim: Thank you for your letter dated November 14, 2007 in which you request additional information regarding San Rio Ocean and River Club; Phases 2 and 3. Below is a response to each of your concerns. 1. Please review the regional conditions for 1VWP 29 and provide proof to this office that you qualify under 4.3, 4.4, and 4.5 (see attached). Wetland crossing #4 is located within the 100-year floodplain. Therefore, we would like to utilize the NWP 12, as originally requested. It appears that the proposed project meets the conditions of this permit. 2. It appears based on your application that impacts to wetlands could be completely avoided by directionally boring the utility line installation under streams and wetlands. Please explain why this alternative was not considered and why it may/may not be practicable (NWP General Condition #20(a)). The applicant evaluated the possibility of directionally boring utilities under all wetland/stream crossings. However, costs were too great, especially when taking into account that they are already incurring the cost of several bridges to avoid permanent impacts. Please note that the revised site plan (enclosed) shows two additional utility crossings through wetlands that will be directionally bored to further minimize impacts (Insets 5 and 6). 3. Please provide a fill size map. Please see the attached 24" x 36" map. www.lmgroup.net • info@Imgroup.net Phone: 910.452.0001 Fax: 910.452.0060 3805 Wrightsville Ave., Suite 15, Wilmington, NC 28403 • P.O. Box 2522, Wilmington, NC 28402 4. Please clarify the need for Impact # 1. Wetland Span #1 will provide access to an amenity center located within Phase 2. The site plan has been revised to show the approximate location of the amenity center. S. No mitigation is proposed for this project. This offrce recommends full preservation of the waters and wetlands orz-site using one of the models on ozrr website (see attached) to avoid secondary and cumzrlative impacts associated with the construction of this subdivision. The applicant is proposing only temporary wetland and stream impacts for the installation of utilities. Impacts have been minimized through careful site planning including the construction of several bridges and directional bores to avoid permanent impacts. Therefore, no further mitigation is offered. 6. Please clarify the nature of the sewer line violation issued by the State that occurred on the property. With regards to the NCDENR Notice of Violation, the developer had portions of the sanitary sewer force main installed prior to obtaining the State permit. No sewer flow entered the installed pipe, nor was the pipe ever connected to any existing sewer. It is basically a buried line serving no current purpose. The NCDENR sewer permit has since been issued for the sewer in question. At no time did the installed sewer line disturb wetlands. I hope this response adequately addresses all of your comments.
