PO Box 3234 Wilmington, NC 28046 Subject Property: Watermark Landing REQUEST FOR MORE INFORMATION Dear Mr. Wrangell: On August 16, 2006, the Division of Water Quality {DWQ) received your application dated August 14, 2006 to impact 039 acres of wetlands to construct the proposed 33 unit duplex family residential development. The DWQ has determined that your application was incomplete and/or provided inaccurate information as discussed below: The DWQ will require additional information in order to process your application to impact protected wetlands and/or streams on the subject property. Therefore, unless we receive the additional information requested below, we will have to move toward denial of your application as required,by 15A NCAC 2H .0506 and will place this project on hold as incomplete until we receive this additional information. Please provide the following information so that we may continue to review your project. Additional Information Requested: 1. It appears that one of the proposed road crossings is located in Coastal Wetlands. Fill of Coastal Wetlands is not allowable unless the activity is water dependent. Even if there is an existing dirt road and/or culvert, widening this road is not an option. Abridge is the only option. 2. The proposed development appears to fall under the Coastal Area Management Act regulations and a CAMA Major Permit may be required for the project. Please discuss this matter with the Division of Coastal Management {DCM} Representative, Robb Mairs. If a CAMA Major is required for the project, your project will be placed on hold until DWQ receives a complete CAMA Major application from DCM. 3. Please also consider reducing the total wetland impacts on the project site to less than 1/10 of an acre of impacts to 404 Wetlands. Filling greater than 1/ZO of an acre of wetlands adjacent to tidal water is rarely permitted and often requires the applicant to go through the Individual Pezxnit process with the US Army Corps of Engineers (USAGE) and the Individual Certification Process with DWQ. The USAGE will ultimately make this determination, but rninirrlization and avoidance is required. Please nose that bridging road crossing numbers 5 and 6 would get the total impacts under the-1/1.0 and would satisfy DWQ's minimization and avoidance issues.

It is highly recommended that you request a pre application meeting with the USACE, DCM, and DWQ prior to submitting a new and revised application. Please respond within three weeks of the date of this letter by sending this information to me in writing and 5 copies of the information to Cyndi Karoly of the DWQ Oversight Unit Office. If we do not hear from you within three weeks, we will assume that you no longer want to pursue this project and we will consider the project as withdrawn. This letter only addresses the application review and does not authorize any impacts to wetlands, waters or protected buffers. Please be aware that any impacts requested within your application are not authorized (at this time) by th_e DWQ. Please call me at 910-797-7215 or Cyndi Karoly at 919-733- 1786 if you have any questions regarding or would like to set up a meeting to discuss`this matter.

DEPARTMENT OF THE ARMY WILMINGTON DISTRICT, CORPS OF ENGWEER$ PO BOX 7894 WILMINGTON NC 284D2-1894 September 20, 2006 Regulatory Division Action ID No. SAW-2001-1253-065 Stomac, LLC Attn: Mr. Ken Wrangell Post Office Box 3234 Wilmington, North Carolina 28402 Dear Ivir. Wrangell: }:, .r: ~ R.~ ~t3 '' On August 16, 2006, this Office received a request from your Authorized Agent, McKim & :, - - onv~n e errru N WY) 14 for impacts to u.jy acre or jurisdictional wetlands adjacent to the Cape Fear River, for road crossings associated with the proposed Watermark Landing residential development. The proposed project area is a 64.62 acre parcel located along the westside of River Road, south of Sanders Road, directly across from The Cape $oulevard, south of Wilmington, New Hanover County, North Carolina. Upon review of your application, this Office has determined that your application is incomplete and cannot be processed until the following information is received: 1. Your project does not qualify for verification under Nationwide Permit_ 14, since the Wilmington District's Final Regional Conditions for Nationwide Permits (May 2002} prohibit the use of NWP 14 for private protects located in tidal waters or tidal wetlands. 2. Based on a telephone conversation on September 18, 2006 with Mr. Robb Mains of the N.C. Division of Coastal Management, it appears that your project would require a CAMA/Corps Major Development Permit. Please contact Mr. Mains at 910-796- 7423. If you decide to proceed with your proposal as designed, then your request will be processed as a CAMA/Corps Major Development Permit. 3. If you redesign your project to avoid the joint CAMA/Corps Major permitting process and your total project impacts to jurisdictional wetlands exceed 0.10 acre, then you will be required to apply for Department of Army (DA) authorization through the Individual Permit process. Tf less. than 0.10 acre of wetland impact for the entire project, then you maybe eligible to utilize NWP 18. -2- 4. Please be aware that, regardless of the permitting scenario, you must demonstrate that you have avoided and minimi~.~d impacts to the maximum extent practicable. You must provide an alternative analysis, which may include off-site alternatives for an Individual Permit. We cannot issue DA authorization if we determine that your proposal is not the least environmentally damaging practicable alternative. 5. Please be aware that your mitigation proposal is insufficient. While we appreciate and support on-site preservation, we will require a minimum 1:1 in-kind replacement. This may be accomplished through on-site restoration (1:1), creation (4:1); or payment into the N.C. Ecosystem Enhancement Program (2:1) or a combination of restoration!enhancement/payment with preservation of the all the remaining wetlands. Please contact this Office to discuss your options and the requirements for a complete mitigation proposal. Please submit the above information within 30 days of receipt of this Notification or we will consider your application withdrawn and close the file. If you have any questions regarding these matters, please contact me at (910} 251-4923. Sincerely, Jennifer S. Frye, Regulatory Specialist Wilmington Regulatory Field Office Copies Furnished: Ir.

It may be useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. Roadway wetland crossings have been avoided and minimized by crossing at the narrowest widths and reducing pavement sections at the crossing areas Sub-aqueous utilities will be located within these fill areas to eliminate additional impacts Alterative designs were proposed. See narrative for further details. VIII. Mitigation DWQ - In accordance with 1 SA NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. Page 9 of 12 USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2 o.enr.state.nc.us/ncwetlands/strmgide.html. 1. Provide a brief description of the proposed mitigation plan.

U i 5 Figure 1 -Site Vicinity Map The existing site is undeveloped and sparsely to moderately wooded with undisturbed upland and wetland areas with mature trees and under story growth. The New Hanover County SCS Soil Survey indicates that the predominate soil within the project limits site is Kureb sand (Kr). The remainder of the property boundary contains Leon sand (Le), Borrow pits (Bp), Lynn Haven fine sand (Ly), and Dorovan soils (DO). All of these soil types have well drained soils that have a sand and fine sand surface layer and a sand, fine sandy loam, and loamy fine sand subsoil or underlying layer; on uplands. The seasonal high water table is greater than 6 ft below grade. Page 1 The proposed project area discharges to Cape Fear River. Cape Fear River is within the Cape Fear River Basin and is classified SC. The classification is dated 08/09/81 and the stream index number is 18-(71). Wetlands and Coastal Marsh are located within the property boundary; these areas will be excluded and protected from construction activity. Proposed Improvements The proposed development of this 64.62 acre tract of land will be for 33 duplex residential homes with, an average lot size approximately. 0.10 acres. To provide a safe finished floor elevation, the existing uplands will be built above the 100-year flood elevation (10.0 ft) and protected with the installation of treated timber bulkheads. The bulkheads will prevent a sufficient amount of impact to the wetlands and prevent any future accidental disturbances. The improvements will consist of the clearing and grubbing, wall installation, bridge installation, cross drainage piping, fill material, roadway and utilities construction. The project is being pursued as high density. Wetlands have been excluded from the impervious area percentage calculation. The impervious area is based on the total property minus the wetland area. The impervious area will be 66,644 sf of roadways, a 12,685 sf clubhouse, 31,680 sf of driveways, and 33-lots totaling 74,280 sf, making the total built upon area 185,289 sf, 62.8% of the 294,900 sf drainage area. To further diminish the adverse environmental effects on surface water quality resulting from development, stormwater will be treated via infiltration trenches. To maximize the stormwater runoff treatment and avert possible erosion, roof drains shall tie into the infiltration trenches. As a comparison to ponds, infiltration trenches BMPs reduce adverse effects of changes in land use on the aquatic environment. Emergency overflow devices will be set at the 50-yr event in each individual system. Both the county stormwater regulations and state stormwater regulations will be accommodated. NCDENR has issued stormwater Permit No. SW8 060630 and New Hanover County has returned Approved drawings with signatures. Several design concepts have implemented throughout the project history. The project has been designed and constructed to avoid and minimize adverse effects to waters of the US to the maximum extent practicable at the project site. Given the limited uplands, options were limited. Avoidance and Minimization The infrastructure has been carefully designed to limit the wetland impacts. The utility trench will not be constructed with extensive gravel layers of backfill, creating a french drain effect. The sewer line will be in the center of the roadway. The waterline will be will 5 ft from the edge of pavement. The force main, where applicable, will be on the opposite side of the roadway, 5 ft from the edge of pavement. The utilities will be within the roadway right-of-way. The width of the fill is limited to the minimum necessary for a safe crossing. The right-of-way width has been reduced from 50 ft to 40 ft, to further reduce wetland impacts. While the roads have been designed to meet NCDOT specifications and New Hanover County requirements they will be privately dedicated. To further limit wetland impacts, interconnectivity and cul-de-sac lengths were not obtainable based on the site characteristics. Emergency vehicle "hammer-heads" are provided in lieu of cul-de-sacs. Of the 64.62-acre tract of land, 51.13 acres of wetlands are on the property. Two areas of wetlands totaling 0.190 acres will be permanently impacted as a consequence of development. Page 2 An additional 0.037 acres will be temporarily impacted during construction. The wetland disturbance is a requirement for roadway and utility crossings. Excluding the 0.190 acres of wetlands to be disturbed, the remaining wetlands will remain at a 2:1 ratio preserved through a home owners association. Due to the existing characteristics of the site, neither on-site restoration nor creation will be an option. The owner proposes payment into the NC Ecosystem Enhancement Program. The impacted areas that are designated as wetlands are typically dry. Culverts will be installed to provide equalization of the wetlands during sufficient storm events. The stream cross section will be placed to its original grade and elevation. The ends of the pipes will be flush with bulkheads with a flared end sections. The flared end sections provide a more smooth transition of water movement. To promote the safe passage of fish and other aquatic organisms, the pipes will be buried 20 percent of the culvert diameter. The 20 percent burial will limit the disruption of the necessary life-cycle movements of those species of aquatic life indigenous to the water body, including those species that normally migrate through the area. Due to the negligible flow and to prevent further disturbance, rip rap will not be used. Orange safety fencing will be installed along the wetland perimeters which are within 100 ft of construction activities. Details, cross sections, and blowups can be found on sheets CN-101. The temporary impacts will occur as the bulkheads are being installed. This includes temporary construction mats (e.g., timber, steel, geotextile) used during construction and removed upon completion of the work. Temporary silt fence will be installed as erosion control measures. Silt fencing will be used as noted on the plans and as needed. The length of proposed silt fence does exceed the 100 ftper'/4 acre of disturbed area criteria. To restore the temporary impacts, the areas will be backfilled with 6 inches to 12 inches of topsoil taken from the disturbed area. The areas will be restored to preconstruction contours and elevation. Temporary cleared wetland areas shall be re-vegetated to the maximum extent practicable with native species of canopy, shrub, and herbaceous species. Fescue grass shall not be used. To avoid further wetland impacts, the uplands off Skipjack Trail will be connected via bridge with pilings. The pilings will be placed on the uplands surrounded by bulkheads, the bridge will span from one upland to the neighboring upland. Utility line construction will be attached to the underside of the bridge structure. The bottom of the bridge will be approximately 6 ft above the water surface, providing more than adequate space for the utilities of three residential units. The construction of utilities in this area will not impact the wetlands in any manner. Several discussions and site visits have taken place with representatives of the Division of Coastal Management. To install a bridge, the DCM will require a CAMA Minor Permit. The area of concern will not be impacted by culverts, fill, or any other permanent impacts. Construction activities will not commence until a copy of the approved CAMA permit is furnished to USACE and NCDENR. Attached is a proposal from Steadfast Bridges, which provides construction details To further diminish the adverse environmental effects on surface water quality resulting from development, stormwater will be treated via infiltration trenches. To maximize the stormwater runoff treatment and avert possible erosion, roof drains shall tie into the infiltration trenches. As a comparison to ponds, infiltration trenches BMPs reduce adverse effects of changes in land use on the aquatic environment. Emergency overflow devices will be set at the 50-yr event in each individual system. Both the county stormwater regulations and state stormwater regulations will be accommodated. NCDENR has issued stormwater Permit No. SW8 060630 and New Hanover County has returned Approved drawings with signatures. Page 3 New Hanover County strictly enforces their 75 ft COD Buffer regulation. New Hanover County will allow road crossings if no other alternative can be provided. McKim & Creed, PA originally proposed the idea of connecting Marada Way and Lanyards End through the 75 ft COD Buffer. New Hanover County denied this option due to the accessibility of a connection to Diligence Trail without impending the 75 ft COD Buffer. New Hanover County did not favor the idea of placing a road in this area, as the bulkheads would restrict any natural flow and create a pocket of isolated wetlands. Due to other 75 ft COD Buffer crossings, New Hanover County felt this crossing would be excessive and not critical, as other options are available. Additionally, the horizontal alignment of the roadway would create further wetland impacts of approximately 0.08 acres. Another proposed option to limit wetland disturbance, was to install a bridge structure connecting Diligence Trail and Lanyards End. Wetland disturbance would not be completely eliminated. For a structure to span the 250 ft crossing, a support would be required midway, with a permanent impact of 0.07 acres. Attached is a proposal from Steadfast Bridges, which provides construction pricing for structures only. From previous work, McKim & Creed, PA adds additional 40 percent to the price of the structure to encumber the foundation. From the supplied cost estimate, McKim & Creed, PA estimates the cost of bridges to approximately $915,000.00. This price does not include construction labor and equipment. The property value of the 9 lots the bridge served would not be able to justify this additional construction cost. If this option were chosen, the owner would not be able to encumber the cost of construction through the sell of the lots. The cost would outweigh the profit, creating a net project loss. To maximize the use of the land available on the property, McKim & Creed, PA has explored various options to limit wetland disturbance and abide by New Hanover County regulations. Of the 64.62-acre tract of land, 51.13 acres of wetlands are on the property. Two areas of wetlands totaling 0.190 acres will be permanently impacted as a consequence of development (0.37% of the total wetlands). Maintenance Sediment will be removed from the infiltration system annually or when the depth in the unit is reduced to 75% of the original design depth. A benchmark shall be established in each individual infiltration system. The system shall be restored to the original design depth without over excavating. Removed sediment shall be hauled offsite. To ensure public safety, the bulkhead retaining wall shall be inspected and maintained annually and after a sufficient storm event. Upon completion of construction and the establishment of stabilizing ground cover, the property owner shall be responsible for site maintenance.

Below is a timeline and a brief explanation of what you can expect working with us. ORDER DEVELOPMENT Once the decision is made by your project planning team to use a Steadfast bridge, we need the following information: Copy of the signed Quote Sheet Steadfast Vehicular Order Form Any Plans and Specs for the Project Steadfast Credit History Report ENGINEERING AND SUBMITTAL Note: If Steadfast is also to do the Abutment Design for your project, we will need Geotechnical data and Soils information. Our Vehicular Engineering Team in Birmingham, AL will use the plans and specifications to custom design your bridge to meet the structual and aesthetic requirements of the project. Since there are no 'off the shelf' designs, this process normally takes 2-3 weeks. As soon as the design is completed, it is sent to the customer for approval. FABRICATION When the drawings are retumed to Steadfast with Approval Stamps , fabrication of the bridge begins. It is important to note Steadfast cannot start fabrication until the drawings are retumed to us approved. Production time will vary depending on size and type of bridge. However, the standard fabrication time is 6 to 8 weeks for Beam Span and 12 -14 weeks for a Truss Bridge. INSPECTION After fabrication, the bridge is completely erected in our shop to ensure all bolt holes line up and the bridge is built to design. This reduces the possibility of problems in the field. SHIPMENT Once the bridge has been fabricated and inspected, the pieces are arranged and placed on a flat bed truck to minimize delivery issues. The bridge will shipped knocked down or in one piece depending on size. The bridge will be delivered as close as possible to the erection site. INSTALL SUPPORT Field Use drawings are sent with each bridge. On the knocked down bridges, each piece is tagged with a number for easy erection. Most installations take 2 to 3 days.
