Erosion and sediment control practices must be in full compliance with all specifications governing the proper design, installation and operation and maintenance of such Best Management Practices in order to protect surface waters standards: a. The erosion and sediment control measures for the project must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Sediment and Erosion Control Planning and Design Manual. b. The design, installation, operation, and maintenance of the sediment and erosion control measures must be such that they equal, or exceed, the requirements specified in the most recent version of the North Carolina Sediment and Erosion Control Manual. The devices shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects, including contractor-owned or leased borrow pits associated with the project. c. For borrow pit sites, the erosion and sediment control measures must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Surface Mining Manual. d. The reclamation measures and implementation must comply with the reclamation in accordance with the requirements of the Sedimentation Pollution Control Act. e. Sufficient materials required for stabilization and/or repair of erosion control measures and stormwater routing and treatment shall be on site at all times. 3. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the impacts depicted in the 404/401Permit Application. All construction activities, including the design, installation, operation, and maintenance of sediment and erosion control Best Management Practices, shall be performed so that no violations of state water quality standards, statutes, or rules occur; 4. Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored within six months of the date that the Division of Land Resources has released the project; Continuing Compliance: 5. Mr. Dan Vincent and/or Governors Club Limited Partnership shall conduct construction activities in a manner consistent with State water quality standards (including any requirements resulting from compliance with section 303(d) of the Clean Water Act) and any other appropriate requirements of State law and federal law. If the Division determines that such standards or laws are not being met (including the failure to sustain a designated or achieved use) or that State or federal law is being violated, or that further conditions are necessary to assure compliance, the Division may reevaluate and modify this Certification to include conditions appropriate to assure compliance with such standards and requirements in accordance with 15A NCAC 2H.0507(d). Before modifying the Certification, the Division shall notify Mr. Dan Vincent and/or Governors Club Limited Partnership and the US Army Corps of Engineers, provide public notice in accordance with 15A NCAC 2H.0503 and provide opportunity for public hearing in accordance with 15A NCAC 211.0504. Any new or revised conditions shall be provided to Mr. Dan Vincent and/or Governors Club Limited Partnership in writing, shall be provided to the United States Army Corps of Engineers for reference in any Permit issued pursuant to Section 404 of the Clean Water Act, and shall also become conditions of the 404 Permit for the project; r Mr. Dan Vincent, Governors Club Limited Partnership Page 4 of 5 October 3, 2005 Road Crossings: 6. Culvert Installation Culverts required for this project shall be installed in such a manner that the original stream profiles are not altered. Existing stream dimensions (including the cross section dimensions, pattern, and longitudinal profile) must be maintained above and below locations of each culvert. Culverts shall be designed and installed to allow for aquatic life movement as well as to prevent head cutting of the streams. If any of the existing pipes are or become perched, the appropriate stream grade shall be re- established or, if the pipes installed in a perched manner, the pipes shall be removed and re-installed correctly. The establishment of native, woody vegetation and other soft stream bank stabilization techniques must be used where practicable instead of riprap or other bank hardening methods. If riprap is necessary, it shall not be placed in the streambed, unless specifically approved by the Division of Water Quality. Installation of culverts in wetlands must ensure continuity of water movement and be designed to adequately accommodate high water or flood conditions. Stormwater Management: 7. Since the project is located in a WS-IV, Nutrient Sensitive Waters, it will be required that within 60 days of the issuance of this Certification, a final, written stormwater management plan (including a signed and notarized Operation and Maintenance Agreement) for the 76-Unit Townhomes (proposed developed area west of Village Pond) and the 49-Lot residential subdivision (proposed developed area east of the Village Pond) shall be approved in writing by the Division of Water Quality's Wetlands Unit. The facilities must be designed to remove 85% TSS, as well as treat nitrogen in the runoff from each area by using extended detention wetlands, bio- retention areas, and/or ponds followed by forested filter strips (designed according to latest version of the NC DENR Stormwater Best Management Practices Manual). Also, before any permanent building or other structure is occupied in each area, the facilities (as approved by the Wetlands Unit) for that area shall be constructed and operational, and the stormwater management plans for these areas (as approved by the Wetlands Unit) shall be implemented. The structural stormwater practices as approved by the Wetlands Unit as well as drainage patterns must be maintained in perpetuity. No changes to the structural stormwater practices shall be made without written authorization from the Division of Water Quality. However, in an effort to be accommodating to what may be unique site specific constraints DWQ will accept an equivalent amount of presently untreated onsite stormwater to offset the new impervious surface that is being proposed to occur with these project areas (Our hope is that this would be easier site specific constraints). Other conditions: 8. Certificate of Completion Upon completion of the project, the Applicant shall complete and return the enclosed "Certificate of Completion" form to notify NCDWQ when all work included in the §401 Certification has been completed. The responsible party shall complete the attached form and return it to the 401/Wetlands Unit of the NC Division of Water Quality upon completion of the project. Please send photographs upstream and downstream of each culvert site to document correct installation along with the Certificate of Completion form. Mr. Dan Vincent, Governors Club Limited Partnership Page 5 of 5 October 3, 2005 9. Protective Fencing The outside buffer, wetland or water boundary and along the construction corridor within these boundaries approved under this authorization shall be clearly marked with orange warning fencing (or similar high visibility material) for the areas that have been approved to infringe within the buffer, wetland or water prior to any land disturbing activities to ensure compliance. 10. Construction Stormwater Permit NCGO 10000 Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of Land Resources (DLR) or a DLR delegated local erosion and sedimentation control program, an NPDES General stormwater permit (NCGO10000) administered by DWQ is automatically issued to the project. This General Permit allows stormwater to be discharged during land disturbing construction activities as stipulated by conditions in the permit. If your project is covered by this permit [applicable to construction projects that disturb one (1) or more acres], full compliance with permit conditions including the sedimentation control plan, self-monitoring, record keeping and reporting requirements are required. A copy of this permit and monitoring report forms may be found at http://h2o.enr.state.iic.uslsu/Forms Documents.htm. 11. Deed Notifications Deed notifications or similar mechanisms shall be placed on all retained jurisdictional wetlands, waters and protective buffers in order to assure compliance for future wetland, water and buffer impact. These mechanisms shall be put in place prior to impacting any wetlands, waters and/or buffers approved for impact under this Certification Approval and Authorization Certificate. A sample deed notification can be downloaded from the 401/Wetlands Unit web site at http://h2o.enr.state.nc.us/ncwetlands. The text of the sample deed notification may be modified as appropriate to suit to this project. Also, this approval to proceed with your proposed impacts or to conduct impacts to waters as depicted in your application shall expire upon expiration of the 404 Permit. If this Certification is unacceptable to you, you have the right to an adjudicatory hearing upon written request within sixty (60) days following receipt of this Certification. This request must be in the form of a written petition conforming to Chapter 150B of the North Carolina General Statutes and filed with the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714.

The current pond lacks a forebay and littoral shelf. In response to the recent 401 approval for the project, modification5 to improve the water duality performance are enclosed. The ex15tmg pond will be divided into an upper and lower pond. The upper pond will be an extended detention wetland acting also a5 a forebay for the lower wet pond. The extended detention wetland basin has been Sized to the largest available volume given ex15ting Site con5tramt5. Patrick 5mith with S*EC has prepared a grading plan for the wetland basin providing small forebay5 at all 5tormwater entry points. Variation of elevation within the wetland ba5m has been provided to accommodate a wide range of plant 5peoe5. S*EC has also prepared a detailed planting plan with 5pecification5. The lower pond has been redesigned to meet the surface area / drainage area and temporary pool recluirement5 for the I " storm event. The existing 5pdiway has been analyzed and determined to be acceptable with the exception of the drawdown orifice which. will be mcrea5ed from 4 - G" in 51ze. A 10' littoral shelf has also been provided. There 15 one existing dramage outfall from a 5mc3le family re51dential phase that d15charge5 directly into the wet pond.

Identify required lines, levels, contours, datum, elevations, and grades necessary for construction as shown on the drawings. B. Notify utility companies to remove or relocate public utilities that are in conflict with proposed improvements. C. Protect plant life, lawns, fences, existing structures, sidewalks, paving, and curbs, unless otherwise noted on the drawings from excavating equipment and vehicular traffic. D. Protect benchmarks, property corners, and other survey monuments from damage or displacement. If marker needs to be removed it shall be referenced by licensed land surveyor and replaced, as necessary, by same. E. Foundation Preparation. Site grading should initially begin with the removal of all vegetation and topsoil from within the limits of the proposed axis of the new dam. The stripped materials may be wasted below normal pool on the interior of the reservoir or be stockpiled for reuse in landscaping other portions of the project. Following removal of all topsoil materials, the foundation of the dam should be proofrolled with a loaded dump truck or similar piece of equipment under the observation of a geotechnical engineer to identify any areas needing additional repair. Based on the results of the test borings, and a probe rod inspection of the dam axis performed utilizing a half inch diameter steel probe rod, we anticipate that repair depths will not exceed about 12 to 24 inches in most areas provided that site grading operations are conducted during the typically warmer and dryer summer months. If the site is graded during the cooler and wetter winter months, we anticipate that the contractor will encounter more significant areas of instability. Repairs at the bottom of the stream channel should be minimal since hard silts are present near the base of the channel; however, some deeper repairs could be required along the bank of the channel 02300-3 -Governors Village Pond 03/27/06 f Prior to placement of the first lift of soil, the subgrade should be scarified, moisture conditioned as necessary, and a thin lift of new fill placed prior to initial compaction. This procedure is recommended in order to provide for a less distinctive boundary between the fill and virgin soil. In the event that permeable near surface soils are encountered once site grading begins, consideration could be given to constructing a key trench at the foundation level near the center of the dam.

Field density tests for in-place materials will be performed by the Owner's Independent Testing Laboratory (ITL) as follows: During actual construction, density tests should be performed at the rate of one test per 5,000 to 10,000 square feet of fill material placed per lift. The field compaction control should be provided on a full-time basis to identify any potential problem areas. Additionally, compaction should be achieved with a trapezoidal wedge foot type compactor such as a CAT 815 or with a sheep's foot compactor to minimize the potential for developing seepage paths through the new embankment fill. As the fill is placed, rolling can be performed perpendicular to the axis of the dam in order to tie the new fill into existing grade. Fill materials may be placed at moisture contents 2% dry of optimum to the maximum percentage wet of optimum which will still allow achievement of required compaction and sufficient stability to allow obtainment of compaction with subsequent lifts. All fill soils should be compacted to a minimum of 95% of the standard Proctor maximum dry density. B. Corrective Measures For Non-Complying Compaction: Remove and recompact deficient areas until proper compaction is obtained at no additional expense to Owner. Adjust moisture content as necessary to conform to the requirements of this section.

The planting hole or trench shall be deep and wide enough to permit roots to spread out and down without J-rooting and be at least two times the diameter of the rootball taking care not to plant the tree too deeply. The rootball shall be placed on solid soil and not loose backfill. Topsoil and subsoil shall be kept separate during excavation. Soil shall be replaced around the tree and tamped to eliminate air pockets. Fill the hole in stages, starting with topsoil and adding subsoil S&EC Project No. 9325.W 1 Governors Pond Modifications Technical Specifications March 2006 near the top. A 5- to 6- inch layer of organic mulch must be placed on the soil surface around the plant. The plant stem should be upright upon completion of installation. Trees over five feet tall will require staking. At a minimum the upper one-third of the burlap shall be removed and disposed of. The holes for the B&B trees must not be dug more than a few hours in advance of planting since it may fill with water preventing planting. If the hole fills with water during digging, the site is too wet and tree roots will `drown'. Planting should be delayed until conditions improve. In addition, leaving a hole overnight may cause frost to build up in the hole that can damage newly planted tree roots. Containerized Plants No planting shall be done when the temperature is below 32°F, when soil to be excavated for the plant hole is frozen, when the sides or bottom of the plant hole are frozen, or when the soil to be used for backfilling is frozen or too wet. In digging, loading, transporting, unloading, planting, or otherwise handling plants, the Contractor shall exercise utmost care and use adequate precautions to prevent injury to or drying out of the trunk, branches, or roots as well as prevent freezing of the plant roots. Container vegetation must always be handled by the container and never by the tops of the plants. Installation of container vegetation shall be located in designated areas as described in the plans and as directed by the Designer. Soil in the area of planting shall be loosened to a depth no less than the height of the container. Container vegetation can be planted in holes made by a shovel or other means that meet the approval of the Designer. Hoedads and dibble bars may not be used. The container shall be properly disposed of. Container stock shall be planted in a vertical position with the root collar approximately 0.5 inches below the soil surface. The planting trench or hole shall be deep and wide enough to permit roots to spread out and down without J-rooting. After planting, the soil shall be tamped firmly to eliminate air pockets. A 3- to 4-inch layer of organic mulch must then be placed on the soil surface around the plant. General Planting records shall be maintained by the Installer to ensure appropriate size and percentage of each plant species as described in the Planting Schedule. Record of nursery or provider shall be maintained for all plant material. Planting records shall be provided to the Engineer and Owner upon completion of planting installation. Unless specifically described on the Planting Plan (as shown for Specimen Plantings), tree, shrub and herbaceous plantings shall be randomly intermixed across the Deep Water, Saturated, and Slope planting zones. Care should be taken to avoid planting forest species too deep or too shallow, and to avoid damage to root systems during planting. Planting depth should be in accordance with listed references, supplier recommendations, and planting details. 4.11 EMERGENT AND AQUATIC PLANTINGS Where herbaceous emergent marsh and aquatic marsh planting is directed, areas shall be planted with plugs, bare roots, tubers/rhizomes of selected plant species as shown on construction plans. Stems shall be planted at spacing shown on Drawings. S&EC Project No. 9325.W I Governors Pond Modifications All plants will be installed in accordance with the recommendations of the supplying nursery. If not planted immediately upon delivery to the job site, the plant material shall be stored out of direct exposure to the sun and wind and they shall be protected by covering with straw, peat moss, compost, or other suitable materials and shall be kept moist, through periodic watering, until the time of planting.

PROJECT SUMMARY: The proposed rev151on5 include modification of an ex15tmg 4 AC wet pond that provides a temporary storage pool for the 0.5" storm event. The current pond lacks a forebay and littoral shelf. In response to the recent 401 approval for the protect, modifications to improve the water quality performance are enclosed. The existing pond will be divided into an upper and lower pond. The upper pond will be an extended detention wetland acting also a5 a forebay for the lower wet pond. The extended detention wetland basin has been Sized to the largest available volume given existing Site con5tramt5. Patrick 5mith with S*EC has prepared a gradmg plan for the wetland ba5m providmg small forebay5 at all 5tormwater entry points. Variation of elevation within the wetland basin has been provided to accommodate a wide range of plant 5peae5. S*EC has also prepared a detailed planting plan with 5peufication5. The lower pond has been redesigned to meet the surface area / dramage area and temporary pool requirement5 for the I " storm event. The existing Spillway has been analyzed and determined to be acceptable with the exception of the drawdown orifice which. will be mcrea5ed from 4 - G" in Size. A 10' littoral shelf has also been provided. There 15 one ex15tmg dramage outfall from a 5ingle family re5idential phase that d15charge5 directly into the wet pond. A rip rap or gabien Iforebay has been provided for th15 lone outfall. The remainder of the watershed 15 directed into the extended wetland first. 2 ....._... ...... _.-'---•-'.'"...

If marker needs to be removed it shall be referenced by licensed land surveyor and replaced, as necessary, by same. E. Foundation Preparation. Site grading should initially begin with the removal of all vegetation and topsoil from within the limits of the proposed axis of the new dam. The stripped materials may be wasted below normal pool on the interior of the reservoir or be stockpiled for reuse in landscaping other portions of the project. Following removal of all topsoil materials, the foundation of the dam should be proofrolled with a loaded dump truck or similar piece of equipment under the observation of a geotechnical engineer to identify any areas needing additional repair. Based on the results of the test borings, and a probe rod inspection of the dam axis performed utilizing a half inch diameter steel probe rod, we anticipate that repair depths will not exceed about 12 to 24 inches in most areas provided that site grading operations are conducted during the typically warmer and dryer summer months. If the site is graded during the cooler and wetter winter months, we anticipate that the contractor will encounter more significant areas of instability. Repairs at the bottom of the stream channel should be minimal since hard silts are present near the base of the channel; however, some deeper repairs could be required along the bank of the channel. 02300-3 -Governors Village Pond 03/27/06 Prior to placement of the first lift of soil, the subgrade should be scarified, moisture conditioned as necessary, and a thin lift of new fill placed prior to initial compaction. This procedure is recommended in order to provide for a less distinctive boundary between the fill and virgin soil. In the event that permeable near surface soils are encountered once site grading begins, consideration could be given to constructing a key trench at the foundation level near the center of the dam. The borings do not indicate that a key trench will be needed; however, the foundation should be inspected to verify these findings. F. Maintain in operating condition existing utilities, previously installed utilities, and drainage systems encountered in utility installation. Repair surface or subsurface improvements shown on The Drawings. G. Verify location, size, elevation, and other pertinent data required making connections to existing utilities and drainage systems as indicated on The Drawings. H. Over excavate and properly prepare areas of subgrade that are not capable of supporting proposed systems. Stabilize these areas by using acceptable geotextile fabrics or aggregate material placed and compacted as specified by the geotechnical engineer. 1. Damages: Contractor shall be responsible for and shall repair any damage to work in place, other contractor's equipment, utilities, residences, highways, roads, railroads, private and municipal well systems, adjacent structures, natural resources, habitat, existing wells, and the excavation. Contractor responsibility shall also include, damage to the bottom due to heave and including but not limited to, removal and pumping out of the excavated area that may result from Contractor's negligence, inadequate or improper design and operation of the dewatering system, and any mechanical or electrical failure of the dewatering system. Remove subgrade materials rendered unsuitable by excessive wetting and replace with approved backfill material at no additional cost to the Owner. 3.2 TOPSOIL EXCAVATION A. Cut heavy growths of grass from areas before stripping and remove cuttings with remainder of cleared vegetative material. B. Strip topsoil to a depth of not less than 6 inches from areas that are to be filled, excavated, landscaped, or re-graded to such depth that it prevents intermingling with underlying subsoil or questionable material. C. Stockpile topsoil in storage piles in areas shown on The Drawings or where directed by Owner. Construct storage piles to freely drain surface water. Cover storage piles as required to prevent windblown dust. Dispose of unsuitable topsoil as specified for waste material, unless otherwise specified by Owner.

Over excavate wet or unstable soil, if encountered, from trench bottom as necessary to provide suitable base for continuous and uniform bedding. Replace overexcavation with suitable and dispose of unsuitable material. B. Trench excavation sidewalls shall be sloped, shored, sheeted, braced, or otherwise supported by means of sufficient strength to protect workmen in accordance with applicable rules and regulations established for construction by the Department of Labor, Occupational Safety and Health Administration (OSHA), and by local ordinances. Lateral travel distance to exit ladder or steps shall not be greater than 25 feet in trenches 4 feet or deeper. C. Perform trench excavation as indicated on the Drawings for specified depths. During excavation, stockpile materials suitable for backfilling in orderly manner far enough from bank of trench to avoid overloading, slides, or cave-ins. D.

At no time during the backfilling operation shall driven equipment be allowed to operate closer than four feet, measured horizontally, to any part of a structure. Under no circumstances shall equipment be driven over any part of a concrete structure or pipe, unless there is a compacted fill of 24" or greater over the structure or pipe. F. The movement of the hauling and spreading equipment over the fill shall be controlled so that the entire surface of each lift shall be traversed by not less than one tread track of heavy equipment or compaction shall be achieved by a minimum of four complete passes of a sheepsfoot, rubber tired or vibratory roller. Fill material shall contain sufficient moisture such that the required degree of compaction will be obtained with the equipment used. The fill material shall contain sufficient moisture so that if formed into a ball it will not crumble, yet not be so wet that water can be squeezed out. 3.7 A. B. 3.8 A. B. C. D. E. PIPE BEDDING Box Culverts shall be placed upon compacted subgrade. The subgrade shall be compacted to a minimum 95% of the standard Proctor ( maximum dry density ). Place geotextile fabrics in locations as specified on the Drawings. TRENCH BACKFILLING Materials used for trench backfill shall comply with requirements as specified herein. Backfill and compact in accordance with fill and compaction requirements in accordance with ASTM D 2321 unless otherwise shown on the drawings. Do not backfill trenches until required tests are performed and utility systems comply with and are accepted by applicable governing authorities.

Verify finished subgrades to ensure proper elevation and conditions for construction above subgrade. B. Protect, subgrade from excessive wheel loading during construction, including concrete trucks, dump trucks, and other construction equipment. C. Remove areas of finished subgrade found to have insufficient compaction density to depth necessary and replace in manner that will comply with compaction requirements by use of material with CBR or LBR equal to or better than that specified on the drawings. Surface of subgrade after compaction shall be firm, uniform, smooth, stable, and true to grade and cross-section. D. Construct temporary ditches and perform such grading as necessary to maintain positive drainage away from subgrade at all times. 3.11 BORROW AND SPOIL SITES A. Comply with NPDES and local erosion control permitting requirements for any and all on-site and off-site, disturbed spoil and borrow areas. Upon completion of spoil or borrow operations, clean up spoil or borrow areas in a neat and reasonable manner to the satisfaction of Owner or off-site property owner, if applicable. 3.12 FINISH GRADING A.

Bring grades to proper elevation. 02300-7 -Governors Village Pond 03/27/06 I- 3. 13 FIELD TESTING A. Field density tests for in-place materials will be performed by the Owner's Independent Testing Laboratory (ITL) as follows: During actual construction, density tests should be performed at the rate of one test per 5,000 to 10,000 square feet of fill material placed per lift. The field compaction control should be provided on a full-time basis to identify any potential problem areas. Additionally, compaction should be achieved with a trapezoidal wedge foot type compactor such as a CAT 815 or with a sheep's foot compactor to minimize the potential for developing seepage paths through the new embankment fill. As the fill is placed, rolling can be performed perpendicular to the axis of the dam in order to tie the new fill into existing grade. Fill materials may be placed at moisture contents 2% dry of optimum to the maximum percentage wet of optimum which will still allow achievement of required compaction and sufficient stability to allow obtainment of compaction with subsequent lifts. All fill soils should be compacted to a minimum of 95% of the standard Proctor maximum dry density. B. Corrective Measures For Non-Complying Compaction: Remove and recompact deficient areas until proper compaction is obtained at no additional expense to Owner. Adjust moisture content as necessary to conform to the requirements of this section.

Specimen trees and shrub species including B&B trees and 3-gallon containerized shrubs have been specifically located for installation across the storm water wetland. Ball and Burlap (B&B) Plants No planting shall be done when the temperature is below 32°F, when soil to be excavated for the plant hole is frozen, when the sides or bottom of the plant hole are frozen, or when the soil to be used for backfilling is frozen or too wet. In digging, loading, transporting, unloading, planting, or otherwise handling plants, the Contractor shall exercise utmost care and use adequate precautions to prevent injury to or drying out of the trunk, branches, or roots as well as prevent freezing of the plant roots. The planting hole or trench shall be deep and wide enough to permit roots to spread out and down without J-rooting and be at least two times the diameter of the rootball taking care not to plant the tree too deeply. The rootball shall be placed on solid soil and not loose backfill. Topsoil and subsoil shall be kept separate during excavation. Soil shall be replaced around the tree and tamped to eliminate air pockets. Fill the hole in stages, starting with topsoil and adding subsoil S&EC Project No. 9325.W 1 Governors Pond Modifications Technical Specifications March 2006 near the top. A 5- to 6- inch layer of organic mulch must be placed on the soil surface around the plant. The plant stem should be upright upon completion of installation. Trees over five feet tall will require staking. At a minimum the upper one-third of the burlap shall be removed and disposed of. The holes for the B&B trees must not be dug more than a few hours in advance of planting since it may fill with water preventing planting. If the hole fills with water during digging, the site is too wet and tree roots will `drown'. Planting should be delayed until conditions improve. In addition, leaving a hole overnight may cause frost to build up in the hole that can damage newly planted tree roots. Containerized Plants No planting shall be done when the temperature is below 32°F, when soil to be excavated for the plant hole is frozen, when the sides or bottom of the plant hole are frozen, or when the soil to be used for backfilling is frozen or too wet. In digging, loading, transporting, unloading, planting, or otherwise handling plants, the Contractor shall exercise utmost care and use adequate precautions to prevent injury to or drying out of the trunk, branches, or roots as well as prevent freezing of the plant roots. Container vegetation must always be handled by the container and never by the tops of the plants. Installation of container vegetation shall be located in designated areas as described in the plans and as directed by the Designer. Soil in the area of planting shall be loosened to a depth no less than the height of the container. Container vegetation can be planted in holes made by a shovel or other means that meet the approval of the Designer. Hoedads and dibble bars may not be used. The container shall be properly disposed of. Container stock shall be planted in a vertical position with the root collar approximately 0.5 inches below the soil surface. The planting trench or hole shall be deep and wide enough to permit roots to spread out and down without J-rooting. After planting, the soil shall be tamped firmly to eliminate air pockets. A 3- to 4-inch layer of organic mulch must then be placed on the soil surface around the plant. All plants will be installed in accordance with the recommendations of the supplying nursery. If not planted immediately upon delivery to the job site, the plant material shall be stored out of direct exposure to the sun and wind and they shall be protected by covering with straw, peat moss, compost, or other suitable materials and shall be kept moist, through periodic watering, until the time of planting. Where plugs. bare roots, and tubers/rhizomes planting is directed, plants shall be placed in shallow holes so that only sprouts are showing above the soil. Care should be taken to avoid planting species too deep or too shallow, and to avoid damage to root systems during planting. Planting depth should be in accordance with listed references and supplier recommendations. 4.12 REMOVAL OF NUISANCE VEGETATION Removal or control of nuisance vegetation shall be performed for a period of 90 days as necessary to ensure adequate survival of specified plant species. See SPECIAL CONTRACT PROVISIONS. 4.13 PLANTING PERIOD The timing of the installation of all plant material onsie shall be coordinated with the Owner and the Designer. 4.14 WATER FOR PLANTINGS The contractor shall install a rain gage and collect daily gage readings at the site. Contractor shall provide initial watering on the day of planting and thereafter at a minimum rate of V per week (including rainfall) for a period of 90 days. Water used in the planting or care of vegetation and plantings shall meet the requirements of Class C fresh waters as defined in 15 NAC 213.200. See SPECIAL CONTRACT PROVISIONS. 4.15 SUBMITTALS Contractor shall submit purchase certificates (or other proof) of all species planted. General END OF SECTION Planting records shall be maintained by the Installer to ensure appropriate size and percentage of each plant species as described in the Planting Schedule. Record of nursery or provider shall be maintained for all plant material. Planting records shall be provided to the Engineer and Owner upon completion of planting installation. Unless specifically described on the Planting Plan (as shown for Specimen Plantings) tree, shrub and herbaceous plantings shall be randomly intermixed across the Deep Water, Saturated, and Slope planting zones. Care should be taken to avoid planting forest species too deep or too shallow, and to avoid damage to root systems during planting. Planting depth should be in accordance with listed references, supplier recommendations, and planting details. 4.11 EMERGENT AND AQUATIC PLANTINGS Where herbaceous emergent marsh and aquatic marsh planting is directed, areas shall be planted with plugs, bare roots, tubers/rhizomes of selected plant species as shown on construction plans. Stems shall be planted at spacing shown on Drawings. S&EC Project No. 9325.W 1 Governors Pond Modifications Technical Specifications March 2006 s SECTION 5 - PERMANENT SEEDING 5.1 SECTION INCLUDES Permanent seeding for permanent site stabilization. 5.2 MEASUREMENT AND PAYMENT See SPECIAL CONTRACT PROVISIONS 5.3 REFERENCES The following Specifications and methods form a part of this specification: NCDENR - Erosion and Sediment Control Planning and Design Manual When the Specifications or Drawings differ from the requirements of the above-referenced documents, the more stringent requirements shall apply. 5.4 GENERAL Permanent seeding shall be executed in temporary lined areas and all other areas which are disturbed during construction activities. In areas where Erosion Control Matting will be installed (if described elsewhere in the project specifications), seedbed preparation and seeding shall be performed prior to the placement of erosion control matting. 5.5 SEEDBED PREPARATION Complete grading before top soiling or preparing seedbeds. Avoid creating steep slopes. Areas where seeding will occur on exposed finished grade shall be disked or harrowed to ensure soil aeration and to increase the surface roughness prior to planting. Apply lime (at 1 tons per acre) and 10-10-10 fertilizer (at 1,400 pounds per acre) evenly across seedbed and work into the top 4-6 inches of soil by discing or other suitable means. Operate machinery on the contour. Rework the surface if soil becomes compacted or crusted prior to seeding. Complete seedbed preparation by breaking up large clods and raking into a smooth, uniform surface. Fill in or level depressions that can collect water. 5.6 SEEDING Apply permanent seeding to seedbed after preparation is complete. Use certified seed for permanent seeding whenever possible. Certified seed is inspected by the North Carolina Crop Improvement Association. It meets published North Carolina Standards and should bear an official "Certified Seed" label. Broadcast seed into a freshly loosened seedbed that has not been settled by rainfall. Mulch must be used on slopes 4H:1 V or steeper and in areas when concentrated water may flow. Anchor mulch with netting in areas subject to concentrated flow. In areas with Erosion Control Matting will be installed, no mulch shall be used and erosion control matting shall be placed within 24 hours of seeding.

Background The Governors Village development is located within the Jordan Lake Watershed Protected Area (WSIV, PA). The pond is designed to treat the 1St one-inch of stormwater off of impervious surfaces flowing to the pond. The required storage volume of the 1St one-inch is approximately 223,845 c.f., while approximately 268,592 cf is shown to be provided between the 6" outflow orifice and the normal pool. The existing outlet structure consists of 6'x6' (inside dimension) concrete riser with one draw down orifice that is currently 4". This orifice will be recored to accommodate a 6" PVC pipe. The existing orifice is at +/- elevation 246.55, which is the current permanent pool level, This orifice will be grouted closed and a new 6" orifice will be cored at elevation 243.7. The top of the existing riser is elevation 247.0 This provides for +/- 3.3 feet of water quality volume that is to draw down within a 2-5 day period. A 10-foot aquatic bench has been provided around the perimeter of the pond at a proposed elevation of 243.7. The proposed bench slopes 6 to 12- inches down as it slopes 10-feet toward the interior of the pond. The purpose of this bench is to encourage aquatic plant life such as reeds and cattails that will occur naturally and aid in water quality. Q-100 Storm Post-Developed at existing pond intake 614 cfs The existing 6x6 box with 42" RCP and concrete emergency spillway can accommodate 751 cfs A existing rip-rap dissapator pad, to aid in erosion, has been provided at the outlet of the barrel from the pond riser structure. The dissapator pad consists of Class B rip-rap 22-inches deep 4-feet wide at outlet and 40-feet long. This dissipater is necessary to maintain the integrity of the existing dam embankment (prevent scour) Sediment will be required to be removed from the proposed stormwater control measure wet pond once all surfaces throughout the proposed development have been permanently stabilized. H. Maintenance of Embankments A. Vegetation The embankment has a ground cover of fescue, which if properly maintained will prevent erosion of the embankment and provide an easy surface for inspection. The grass will be most difficult to obtain in the area subject to water level fluctuation below the top of the riser. Grass should be fertilized every October and April. ? Re-Seeding - periodically re-seeding may be required to establish grass on areas where seek did not take or has been destroyed. Before seeding, fertilizer (12-12-12) should be applied at a minimum rate of 12 to 15 pounds per 1,000 SF. The seed should be evenly sewn at a rate of three pounds per 1,000 SF. The seed should be covered with soil to the depth of approximately %". Immediately following the planting, the area should be mulched with straw. ? Trees & Shrubs - trees, shrubs, and other landscape vegetation should be permitted only as shown on the approved planting plan. ? Mowing - grass mowing, brush cutting and removal of weed vegetation will be necessary for the proper maintenance of the embankment. All embankment slopes and vegetation of spillways should be mowed when the grass exceeds 8" in height. Acceptable methods include the use of weed whips or power brush cutters and mowers. B. Erosion Erosion occurs when the water concentrates causing failure of the vegetation or when vegetation dies and sets up the environment for rill erosion and eventually gullies from the stormwater runoff. The dam should be inspected for these areas. Proper care of vegetative areas that develop erosion is required to prevent more serious damage to the embankment. Rills and gullies should be filled with suitable soil compacted and then seeded. Methods described in Section I-A, on vegetation, should be used to properly establish the grass surface. Where eroded areas are detected, the cause of the erosion should be addressed to prevent a continued maintenance problem. Frequently problems result from the concentration of runoff to one point of the embankment crest instead of a uniform distribution of runoff. This can be corrected by reshaping the crest to more evenly distribute the runoff to areas, which are not experiencing erosion problems. The top of the dam should not be allowed to be used for pedestrian or bicycle traffic. ? Abutment Areas -- the abutment is the line formed where the embankment fill comes into contact with the existing slope. Runoff from rainfall concentrates in these gutter areas and can reach erosive velocities because of the steep slopes. If a normal stand of grass cannot be maintained on the abutments, additional measures may be needed such as jute matting to provide for the establishment of a good ground cover. ? Upstream Embankment Slope - Erosion problems can develop on the upstream face of the dam due to the fluctuation of water level in the pond. This is a result of a combination of wave actions and ground saturation, 2 which occurs from the elevated water levels. The erosion generally occurs as the water level falls and the saturated ground becomes subjected to the wave action. If erosion becomes a problem, it may necessitate the installation of a stone armoring along the zone subject to fluctuating water level. This would consist of 18" of NCDOT Class B stone for erosion control underlain with Mirifi 140 geotextile fabric. It should be centered at the point of the erosion problem and covering an area 2' above and below the approximate center of the eroded area. C. Seepage ? Detection - Seepage may vary in appearance from a soft wet area to a flowing spring. It may show up first as only an area where the vegetation is more lush and darker green. Cattails, reeds, mosses and other marsh vegetation often become established in a seepage area. The downstream abutment areas where the embankment fill and natural ground interface are very common locations for seepage. Also the contact between the embankment and the spillway conduit is a very common location, which is generally attributed to poor compaction around the conduit. Due to the way in which conduits are put in, this is generally most evident on the underside of the conduit. Slides may result from excessively saturated embankment slopes. The natural foundation area immediately downstream of the dam abutment should also be inspected to ensure that "piping" is not occurring underneath the embankment. "Piping" may appear as a "boil" evident as spring carries soil. The soil usually deposits around the boil area and is evident by the sedimentary deposits accompanying it. Seepage can also occur into the spillway conduit through cracks in the pipe or improperly sealed joints. These can be seen by observing the conduit when the water level is high. The movement of the water itself is not dangerous, but if soil particles are being carried with it, then it can create a shortcut for the piping of soil. This might show up on the upstream face of the embankment roughly along the line of the conduit itself. D. Cracks, Slides, Sloughing, and Settlement ? Cracks - the entire embankment should be inspected for cracks. Short, isolated cracks are usually not significant, but larger cracks (wider than W), well-defined cracks indicate a serious problem. There are two types of cracks: transverse and longitudinal. Traverse cracks appear crossing the embankment and indicated difference of settlement within the embankment. These cracks provide avenues for seepage and piping could develop. Longitudinal cracks run parallel to the embankment and may signal the early stages of a slide. In recently built structures, these cracks may be indicative of poor compaction or poor foundation preparation resulting in consolidation after construction. ? Slides - Slides and slumps are serious threats to the safety of an embankment. Slides can be detected easily unless obscured by 3 vegetation. Arch shaped cracks are indications that slides are slipping or beginning to slip. These cracks soon develop into large scarps in the slope at the top of the slide. ? Settlement - settlement occurs both during construction and after the embankment has been completed and places in service. To a certain degree this is normal and should be experienced. It is usually the most pronounced at the location of maximum foundation depth or embankment height. Excessive settlement will reduce the free board (difference in elevation between the water surface and the top of the dam). Any area of excessive settlement should be restored to original elevation and condition to reduce the risk of overtopping. A relatively large amount of settlement (more than 6") within a small area could indicate serious problems in the foundation or perhaps the lower part of the embankment. Settlement accompanied by cracking often precedes failure. ? What to do if seepage, cracks, slides or settlement are detected: If any of the above items are detected there may be signs of significant problems, which could lead, to the failure of the structure. A geotechnical or civil engineer should be consulted regarding the origin of these problems and for the assessment of the appropriate solutions for correcting them. If the professional is not immediately able to inspect the dam, then the bottom drain should be opened and the water level lowered to remove the risk of failure until a professional can observe these problems. E. Rodent Control Generally in this urban environment, rodents are not a problem. Rodents such as ground hogs, muskrats, and beavers are attracted to dams and reservoirs and can be quite dangerous to structural integrity and proper performance of the embankment and spillway. Groundhog and muskrats thrive on burrowing in the manmade earth embankments, which become pathways for seepage. In the event that burrows are detected within the dam, then the rodents should be dealt with by removal. III. MAINTENANCE OF SPILLWAYS & CONTROL STRUCTURES A. Inspection of Spillway Conduits Conduits should be inspected thoroughly twice a year. Conduits should be visually inspected by actually entering the conduit a sufficient distance between the riser structure and the outlet to check all the joints. Because the outlet works tie into the street storm sewer system, catch basins and pipes. Conduit should be inspected for proper alignment (sagging), elongation and displacement at joints, cracks, leaks, surface water, surface wear, loss of protective coating, corrosion and blocking. Problems with conduits most often occur at joints and special attention should be given to them during inspection. Joints should be checked for gaps caused by elongation or settlement and loss of joint filler material. Open joints can permit erosion of the embankment material and possibly the piping of soil material through the 4 joints. Catch basin should be checked for signs that water is seeping along the exterior surface of the pipe where it enters the catch basin. A depression in the soil surface over the pipe may be signs that soil is being removed from around the pipe. ? What to do if problems are detected with the spillway: Retain the assistance of a civil engineer or geotechnical engineer qualified in the design of embankments to perform an inspection of the dam. If in doubt, lower the water surface elevation of the pond until such time as a qualified professional can perform an inspection. B. Trashracks on Pipe Spillways The spillway riser for this dam is the only spillway structure. The intake structure has been fitted with a trashrack to prevent debris from entering the spillway structure. Most of the runoff entering the pond comes in through grated inlets, which have essentially provided filtration of the runoff and should limit the size of the debris that enters the basin to floating debris, which will most likely pass through the trashrack. The opening between the trashrack and riser is smaller than the opening of the outlet pipe. The intent is that any debris, which passes through the trashrack, will be easily passed by the pipe outlet. Maintenance should include periodically checking the rack for rusted or broken sections and repairing as needed. The trashrack should be checked frequently during and after storm events to ensure that it is properly functioning and to remove accumulated debris. IV. OPERATION A. Lake Drains Lake drains should always be operable so that the pool level can be drawn down in case of an emergency or for repairs or maintenance. Lake drain valves or gates that have not been operated for a long time present a special problem. Generally, when draining the pond, it should be drained slowly. Open the drain until a good flow of water is present but not a torrent, so that the water level can be drained over a period of 48 hours or more. Rapidly lowering the water level in the pond can cause permanent damage to the embankment and must be avoided. The gate valve controlling the lake drain should be operated from fully closed to fully opened position at least twice a year. B. Record Keeping Operation of a dam should include recording of the following: ? Semi Annual Inspections - Inspections are to be performed by a qualified registered North Carolina professional engineer, landscape architect, or surveyor. 5 ? Semi Annual Inspection Reports - a collection of written inspection report should be kept on record in Section IV of this manual. Inspection should be conducted annually. Copies should be provided to the owner or homeowner's association. ? Observations - all observations should be recorded. Where periodic inspections are performed following significant rainfall events, these inspections should be logged into the Periodic Inspection, Operation & Maintenance Form in Section IV of this manual. ? Maintenance - written records of maintenance and/or repairs should be recorded on the Periodic Inspection, Operation & Maintenance Form in Section IV of this manual. ? Other Operation Procedures - the owner should maintain a complete and up-to-date set of plans (as-built drawings) and all changes made to the dam over time should be recorded on the as-builts. C. Sedimentation & Dredging Sedimentation from establishing areas tributary to the pond will eventually result in the reduction of the retention pool and eventually will have to be removed. The frequency of this sediment removal can be reduced by ensuring that the site areas around the building be stabilized with a vegetative ground cover such that it restrains erosion. This would include a periodic application of fertilizer and other treatments necessary to promote a stable groundcover and minimize sedimentation to the pond. The maintenance on this pond requires that when the sediment level (as measured from the top of the riser to the sediment pool) is within 5-feet of the top of the riser that the sediment must be removed and the original pond restored. For aesthetic purposes it may be desirable to maintain it prior to this point. Generally, the dredging process begins with the removal of as much water as possible from the deposited silt and so the material can be excavated with conventional equipment for trucking offsite. The removed material should be hauled offsite to a suitable landfill site or mounded somewhere on site and stabilized with a groundcover sufficient to restrain erosion. D.

CE Group, Inc. 1051 Pemberton Hill Road, Suite 201 Apex, NC 27502 Subject Property: Governors Village UT to Cub Creek [NEU03, 16-41-2-10-(0.5), WS-IV, NSW] REQUEST FOR MORE INFORMATION Dear Mr. Ashness: On December 19, 2005, the Division of Water Quality (DWQ) met with you to discuss the subject property in regard to the conditions of the Individual Water Quality Certification dated October 3, 2005. Specifically, the discussion centered on the stormwater management requirements for Governors Village. You proposed to modify the existing pond to meet current DWQ design requirements as listed within the NC DENR Stormwater Best Management Practice Manual, including the construction of a forebay and littoral shelf, and accommodation of the one-inch runoff. This proposal was further discussed and analyzed by DWQ staff. DWQ has determined that this proposal is not acceptable because it does not provide the TN removal efficiency rate that is essential to protect downstream water quality in a watershed with a classification of NSW. In addition, the 401 Certification that we issued required you to treat untreated stormwater and the existing pond does provide some stormwater treatment. Additional Information Requested: 1. Please redesign the existing pond to include an extended detention [constructed] wetland at the north end of the pond. 2. The existing plan appears to have land area between the pond and the walking trail, and thus allow for additional expansion of the pond/constructed wetland. Please reconfigure the pond/constructed wetland to accommodate the volume required by the NC DENR Stormwater BMP Manual.

However given that this is an Individual Certification, I believe that you have more latitude of what you can accept, and the condition approved in the current 401 allows for an alternate plan that provides for comparable treatment. It should also be noted that this is for the completion of an existing development previously approved by DWQ back in 1996 and that the applicant has avoided impacts that they were previously approved to impact back in 1996. They are proposing to upgrade a pond to provide better treatment for the entire watershed rather than to install bioretention areas for just a portion of the watershed. Conceptually this seems to be a better approach. It's just a matter of how much verification of the improved treatment you will require. You can't assume that the existing pond is removing 25% TN unless it is designed as per the current 1999 BMP manual. Since this pond was designed in 1996 and constructed in 1997, it did not include many of the required design parameters listed in the 1999 manual (e.g., forebays, etc.). We can only assume that it would remove 25% TN if we upgrade it to current design requirements. I expect that the TN removal will be the primary topic of our meeting on the 19th. The project engineer will try to provide as much information as we can at this time to further our argument that this upgrade will provide for similar or better TN removal than just providing bio-retention areas for the single family and townhome sections of the development. See you on the 19th.

A site plan for the specific project is included as Exhibit B. One of the conditions (Stormwater Management #7) required the applicant to design and construct facilities capable of removing 85% TSS coupled with a forested filter strip. This requirement was placed upon two new proposed residential sections (49 single family lots and 76 residential townhomes). With the knowledge of existing site constraints and an existing permitted stormwater facility adjacent to each of these proposed phases, the Division also acknowledged that, in lieu of the required stormwater treatment for the two new sections, the applicant could treat an equivalent amount of untreated onsite stormwater to offset the proposed impervious surface area from the future single family and townhomes. Based upon this allowance within the condition, we propose to achieve an equivalent or better outcome than that required by the 401 condition by providing additional treatment of stormwater from the existing development. As we discussed at our meeting with you on November 4, 2005, we will do so by utilizing the existing stormwater pond, which will be modified as described herein and as depicted in Exhibit E. The existing pond does not meet the current design requirements as described within the N.C. DENR Stormwater BMP Manual and as such can not assume the TSS or TN removal efficiencies allocated by the DWQ. If determined to be acceptable by the DWQ, we will modify the existing pond to meet current DWQ design requirements as listed within the N.C. DENR Stormwater BMP Manual. This will include the construction of forebays and a littoral shelf. Also, while the existing pond has an adequate surface area to meet the SA/DA requirements for 0.5" to 1", the existing temporary pool can only accommodate up to 0.5" of runoff from impervious areas. With an adjustment to the exiting riser structure the temporary pool will be able to accommodate up to 1" of runoff from impervious areas. This increase in the temporary pool and with the addition of a forebay and littoral shelf, the pond will achieve the current DWQ design requirements and can assume an 85% TSS removal and 25% TN removal credit for the 1051 Pemberton Hill Road, Suite 201 - Apex, N.C. 27502 Voice (919) 367-8790 - Fax (919) 367-8791 - email mark@cegroupinc.com entire watershed, including the two new sections. Exhibit D reflects the impacts of the entire watershed. Exhibit A and C present the amount of Total Nitrogen reduction achieved by (i) using of a wet pond followed by a forested filter strip to treat stormwater from only the proposed 76 Unit Townhome and 49 lot residential subdivision (the minimum required to satisfy the stormwater condition of the approved 401 Certification), and (ii) by making the proposed improvements to the existing stormwater pond as described above. The following table summarizes this analysis: WQ Improvement TN Generated TN Removed GV Single Family PH 5 and 264.1 Ibs/yr 105.6 Ibs/yr GV Townhome PH 3 Gov. Village with Full Buildout 1371.9 Ibs/yr 343 Ibs/yr and Exist. Stormwater Pond Upgrade Thus, by making the proposed modifications to the existing pond, we are tripling the nitrogen reduction that would be achieved if we only treated the stormwater from the proposed new sections. (Note: While the current pond does not qualify for any nitrogen removal credit, even if you assume that it is actually achieving a 15% nitrogen removal rate, our proposal would still result in greater additional nitrogen removal than that achieved by addressing the new sections alone.)

Re: Governors Village, DOA Action ID 200520149, DWQ Project # 20050810 Chatham County, NC Dear Mr. Smith: On October 3, 2005, The Division of Water Quality approved a 401 Certification for the above-referenced project with additional conditions. A site plan for the specific project is included as Exhibit B. One of the conditions (Stormwater Management #7) required the applicant to design and construct facilities capable of removing 85% TSS coupled with a forested filter strip. This requirement was placed upon two new proposed residential sections (49 single family lots and 76 residential townhomes). With the knowledge of existing site constraints and an existing permitted stormwater facility adjacent to each of these proposed phases, the Division also acknowledged that, in lieu of the required stormwater treatment for the two new sections, the applicant could treat an equivalent amount of untreated onsite stormwater to offset the proposed impervious surface area from the future single family and townhomes. Based upon this allowance within the condition, we propose to achieve an equivalent or better outcome than that required by the 401 condition by providing additional treatment of stormwater from the existing development. As we discussed at our meeting with you on November 4, 2005, we will do so by utilizing the existing stormwater pond, which will be modified as described herein and as depicted in Exhibit E. The existing pond does not meet the current design requirements as described within the N.C. DENR Stormwater BMP Manual and as such can not assume the TSS or TN removal efficiencies allocated by the DWQ. If determined to be acceptable by the DWQ, we will modify the existing pond to meet current DWQ design requirements as listed within the N.C. DENR Stormwater BMP Manual. This will include the construction of forebays and a littoral shelf. Also, while the existing pond has an adequate surface area to meet the SA/DA requirements for 0.5" to 1", the existing temporary pool can only accommodate up to 0.5" of runoff from impervious areas. With an adjustment to the exiting riser structure the temporary pool will be able to accommodate up to 1" of runoff from impervious areas. This increase in the temporary pool and with the addition of a forebay and littoral shelf, the pond will achieve the current DWQ design requirements and can assume an 85% TSS removal and 25% TN removal credit for the 1051 Pemberton Hill Road, Suite 201 - Apex, N.C. 27502 Voice (919) 367-8790 - Fax (919) 367-8791 - email mark@cegroupinc.com entire watershed, including the two new sections.

Exhibit A and C present the amount of Total Nitrogen reduction achieved by (i) using of a wet pond followed by a forested filter strip to treat stormwater from only the proposed 76 Unit Townhome and 49 lot residential subdivision (the minimum required to satisfy the stormwater condition of the approved 401 Certification), and (ii) by making the proposed improvements to the existing stormwater pond as described above.

(Note: While the current pond does not qualify for any nitrogen removal credit, even if you assume that it is actually achieving a 15% nitrogen removal rate, our proposal would still result in greater additional nitrogen removal than that achieved by addressing the new sections alone.)

Bryant, Piegion Coordinator WMM µp -WATER 6RANCH Habitat Conservation Program DATE: 15 June 2005 SUBJECT: Public Notice for Governors Club Limited Partnership for Construction of Governors Village Subdivision (After-the-Fact), Chatham County, North Carolina. Action ID No. 200520149 Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed the subject document and we are familiar with the habitat values of the area. Our comments are provided in accordance with provisions of the Clean Water Act of 1977 (as amended), Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d), and North Carolina General Statutes (G.S, 113-131 et seq.). The project is a mixed use development including single and multi-family residential units and commercial space. Two stream channels flow through the site into a large stormwater pond. The applicant had received permit authorization for all existing and proposed impacts. However, the authorization expired before all impacts were completed. One of the road crossings was constructed after permit authorization expired. The applicant is applying for reauthorization for the unauthorized road crossing and all remaining impacts. Proposed impacts to stream channels resulting from placement of fill material, culverts, rip rap and/or utility lines totals 202 linear feet, including 54 linear feet of temporary impact. Proposed impacts to wetlands resulting from the placement of culverts, fill material, rip rap, and utility lines totals 0.365 acre including 0.034 acre of temporary impact. The applicant proposes 1:1 mitigation for impacts to stream channels and wetlands associated with the project by providing payment into the North Carolina Ecosystem Enhancement Program (NCEEP) for the restoration of 148 linear feet of stream channel and 0.365 acre riparian wetlands. No mitigation for impacts to open waters has been proposed. Unnamed tributaries to Cub Creek flow through the site. Cub Creek is a headwater tributary to the upper New Hope Creek arm of B.E. Jordan Reservoir in the Cape Fear River basin. The upper New Hope Creek arm of B.E. Jordan Reservoir is on the State's 303(d) list of impaired waters. There are records for the federal and state threatened bald eagle (Hallaeetus leucocephalus) near the project site. Mailing Address: Division of Inland Fisheries - 1721 Mail Service Center - Raleigh, NC 27699-1721 Telephone: (919) 733-3633 - Fax: (919) 715-7643 Page 2 15 June 2005 Governor's Village Action ID No. 200520149 Additionally, B.E. Jordan Reservoir supports a diverse fishery including largemouth bass (Micropterus salmoides), crappie (Pomoxis spp.), sunfish (Lepomis spp.), catfish (Ictalww spp.) and striped bass (Moron saxatilis). We hesitate to concur with the piping of stream channels due to the potential for long-term and cumulative impacts. Stream piping and placing fill in aquatic resources can result in significant negative impacts to downstream areas and eliminate fish and wildlife habitat. Stream piping reduces.the infiltration of stormwater and associated pollutants, as well as the dissipation of stream energy. Piping a stream and placing it underground removes both aquatic and terrestrial habitat. Piping a stream channel and filling the wetlands will alter the hydrology of the existing channel and eliminate beneficial functions. Likewise we hesitate to concur with the filling of wetlands due to their wildlife habitat value and the well- known beneficial functions that they provide for flood control and water quality protection. Changes in land use from a primarily forested area to an urban landscape may exacerbate channel degradation and sediment impacts to stream ecosystems due to increased stormwater runoff. Multiple studies have shown that stream degradation occurs at 10% impervious (Schueler 1994; Arnold and Gibbons 1996; Doll et al. 2000; Mallin et al. 2000; May and Horner 2000; Stewart et al. 2000; Paul and Meyer 2001). Since the applicant had previous permit authorization for the proposed impacts, we will not object to the project provided the following conditions are incorporated into the permit to further reduce impacts to fish and wildlife resources. 1. To minimize additional stream impacts, while retaining some measure of wildlife habitat, we recommend that a 100-foot undisturbed, native, forested buffer along perennial streams, and a 50- foot buffer along intermittent streams and wetlands. Maintaining undisturbed, forested buffers along these areas will minimize impacts to fish and wildlife resources, water quality, and aquatic habitat both within and downstream of the project area. In addition, wide riparian buffers are helpful in maintaining stability of stream banks and for treatment of pollutants associated with stormwater runoff. Whereas, a grassed buffer, particularly fescue, is a vegetated buffer but will not provide the necessary and highly valuable functions as discussed for forested buffers. 2. We recommend that all remaining wetlands and streams on the site should be protected from additional impacts by placing them in a permanent conservation easement to prohibit filling, draining, flooding, and excavation. 3. Use bridges for all permanent roadway crossings of streams and associated wetlands to eliminate the need to fill and culvert, where practicable. If culverts must be used, the culvert should be designed to allow passage of aquatic organisms. Generally, this means that the culvert or pipe invert is buried at least one foot below the natural streambed. If multiple cells are required, the second and/or third cells should be placed so that their bottoms are at stream bankfull stage. This will allow sufficient water depth in the culvert or pipe during normal flows to accommodate movements of aquatic organisms. If culverts are long and sufficient slope exists, baffle systems are recommended to trap gravel and provide resting areas for fish and other aquatic organisms. If multiple pipes or cells are used, at least one pipe or box should be designed to remain dry during normal flows to allow for wildlife passage. In addition, culverts or pipes should be situated so that no channel realignment or widening is required Widening of the stream channel at the inlet or outlet of structures usually causes a decrease in water velocity causing sediment deposition that will require future maintenance. Finally, riprap should not be placed on the streambed. 4. To adequately protect streams, it is suggested that impervious surface is limited to less than 10%. Suggested examples to accomplish the <10% impervious goal are using conventional designs at a Page 3 15 June 2005 Governor's Village Action ID No. 200520149 level of <10% imperviousness or using conservation clusters with higher densities, with dedicated open space and other stormwater control measures to mimic the hydrograph consistent with an impervious coverage of less than 100/9. 5. Locate sewers and other utilities as far away from creeks as functionally possible and minimize stream crossings. It is preferable that sewers be located outside the riparian buffers. The directional bore ('installation of utilities beneath the riverbed, avoiding impacts to the stream and buffer) stream crossing method should be used for utility crossings wherever practicable, and the open cut stream crossing method should only be used when water level is low and stream flow is minimal. Manholes or similar access structures should not be allowed within buffer areas. Stream crossings should be near perpendicular (75° to 105') to stream flow and should be monitored at least every three months for maintenance needs during the first 24 months of the project and then annually thereafter. Further, pesticides (including insecticides and herbicides) should not be used for maintenance of rights-of-way within 100 feet of perennial streams and 50 feet of intermittent streams, or within floodplains and wetlands associated with these streams. 6. We recommend that landscaping consist of non-invasive native species and LID technology. Using native species instead of ornamentals should provide benefits by reducing the need for fertilizers, herbicides, and pesticides. Additionally, native species should require less water. Using LID technology in landscaping will not only help maintain the predevelopment hydrologic regime, but also enhance the aesthetic and habitat value of the site. 7. Specialized efforts and techniques are implemented to reduce sediment runoff from construction activities. Excessive silt and sediment loads can have numerous detrimental effects on aquatic resources including destruction of spawning habitat, suffocation of eggs, and clogging of gills of aquatic species. 8. It is our understanding that compensatory mitigation for wetlands is 2:1 for restoration, 3:1 for creation, 4:1 for enhancement and 10.1 for preservation (in combination with appropriate restoration, creation and enhancement). Therefore, we feel that compensatory mitigation for impact to wetlands should be 2:1. Thank you for the opportunity to comment on this project.

It should also be noted that this is for the completion of an existing development previously approved by DWQ back in 1996 and that the applicant has avoided impacts that they were previously approved to impact back in 1996. i They are proposing to upgrade a pond to provide better treatment for the entire watershed rather than to install bioretention areas for just a portion of the watershed. Conceptually this seems to be a better approach. It's just a matter of how much verification of the improved treatment you will require. You can't assume that the existing pond is removing 25% TN unless it is designed as per the current 1999 BMP manual. Since this pond was designed in 1996 and constructed in 1997, it did not include many of the required design parameters listed in the 1999 manual (e.g., forebays, etc.). We can only assume that it would remove 25% TN if we upgrade it to current design requirements. I expect that the TN removal will be the primary topic of our meeting on the 19th. The project engineer will try to provide as much information as we can at this time to further our argument that this upgrade will provide for similar or better TN removal than just providing bio-retention areas for the single family and townhome sections of the development. See you on the 19th.

Division of Water Quality (DWQ) letter dated July 12, 2005 (received on July 14, 2005). This additional information is an amendment to our existing Individual Permit application under review by both the U.S. Army Corps of Engineers (USACE; Action ID No. 200520149) and DWQ (Project No. 05-0810) for the completion of the Governors Village development. USACE June 21, 2005 Letter in response to the June 21, 2005 letter from the USACE regarding comments received during the Public Notice commenting period, we are providing the following supplemental information and proposed modifications. Letters were received from both the U.S. Fish & Wildlife Service (USFWS) and N.C. Wildlife Resources Commission (NCWRC). The comments within the letters were very similar and included concerns over proper erosion and sediment control measures, minimization and avoidance of wetland and stream impacts, protection of remaining wetlands and streams on the Charlotte Office: 236 LePhillip Court, Suite C Concord, NC 28025 Phone: (704) 720-9405 Fax: (704) 720-9406 Greensboro Office: 3817-E Lawndale Drive Greensboro, NC 27455 Phone: (336) 540-8234 Fax: (336) 540-8235 Governors Village Individual Permit Request/ S&EC Project No. 05-9325.w1 July 29, 2005 Page 2 of 5 property, limitations on impervious cover, and a few others. We believe that the proposed development and construction practices in addition to other modifications to these proposed plans as directed and conditioned by the USACE and DWQ will provide adequate measures to address these concerns. Mitigation -A primary concern from both the USFWS and NCWRC appears to be the concern over adequate compensatory mitigation for impacts to wetlands and streams. The applicant had originally proposed a 1:1 mitigation ratio for both wetlands and streams. In consideration of these agency comments as well as discussions with the USACE, the applicant proposes to modify their mitigation plan (by copy of this letter) to provide mitigation ratios of 1:1 for the 148 feet of permanent stream impacts associated with a road crossing, and 2:1 for the 0.365 acres of wetlands proposed to be impacted. We believe these ratios to be appropriate as typically required to replace the quality and functions of streams and wetlands similar to those proposed to be impacted by this development. Payment into the Wetlands Restoration Fund administered by the N.C. Ecosystem Enhancement Program (EEP) is proposed to satisfy this mitigation. EEP has accepted our request to make this payment. The payment will be made immediately following the approval of the 404 Permit and prior to any additional impacts occurring at the site. In addition to the changes to the proposed mitigation plan, the applicant proposes to avoid any additional, future impacts to wetlands and streams within the development. In addition to the USFWS and NCWRC letters, a letter was received from Sue and John Carpenter of 256 Old Farrington Road (adjacent neighbors to the development). The letter addresses concerns over continued commercial and residential growth, impacts to water quality and the drinking water supply, and the loss of wetlands and streams. Given that the proposed impacts are less than those previously permitted, stormwater management is and will be provided by the Village Pond, impervious surfaces have been reduced and open space will be preserved, we believe that the concerns of Mr. and Mrs. Carpenter have been addressed. The County, other responsible municipalities, and the DWQ will ensure that safe drinking water standards will be maintained. Finally, Mr. Tugwell informed us during our meeting on June 30, 2005 that the North Carolina Department of Cultural Resources made a request after the closing of the comment period for the Public Notice to provide photographs of all structures older than 50 years located on the property. There is one structure located within the area of the 49-Lot Residential Subdivision that is described in the Chatham County Property Records as constructed in 1900 making this structure 105 years old. Photos of this house are attached. It is not documented as a historic resource by Cultural Resources (see their letter dated February 22, 2005 provided within the original application). The house is currently vacant. Vinyl siding and windows were installed on the house some time the past. We have contacted the Harris family and they cannot document when the house was built, but did state that the house was never used as a Harris family home. This house will be deconstructed or otherwise removed to allow for the construction of the new 49-lot subdivision. DWO July 12, 2005 Letter Road Crossing Impact # 2 - Concerns have been raised as to the location and alignment of the road crossing to the existing townhomes north of Village Pond from the existing commercial area and Village Park Drive Extension. Governors Village Individual Permit Request / S&EC Project No. 05-9325.w1 July 29, 2005 Page 3 of 5 Alternative 1 (Existing Preferred Alternative) - The existing location aligns David Stone Drive to Village Park Drive Extension at a standard perpendicular intersection. The existing location impacted a section of the stream channel previously impacted during the construction of the Village Pond and avoided impacts to the stream and wetlands to the north that had not been impacted during the construction of the Village Pond. As such, we believe this alternative is the most practical and the least damaging alternative to water quality. Alternative 2 (Relocating to South) - The possible relocation and realignment of David Stone Drive to the south towards Village Pond was proposed as a solution to potentially minimize impacts to the stream. This alternative would add additional impervious surface within the vegetated riparian area around Village Pond and would allow for potentially more pollutants carried via overland stormwater flows to the pond. This alternative would also require significant grading due to the steep slopes west of the pond. This alternative would not directly align to the intersection with Village Park Drive Extension. Finally, this alternative would require the removal of mature hardwood trees including five oak trees at least 20 inches in diameter (see attached photos). The current plan for the townhomes west of the Village Pond and the existing location of the road crossing (Impact #2) avoids these trees. As such, we do not believe this alternative to be practical nor do we believe that this alternative will increase water quality benefits. Alternative 3 (Relocating to North) - The possible relocation and alignment of this road to the North would require additional permanent impacts to the remaining wetlands and stream. Would not align with David Stone Drive south of the townhomes, but rather "T" into the alley behind the townhomes. As such, we do not believe this alternative to be practical nor do we believe that this alternative will increase water quality benefits. Stormwater - Additional information regarding the anticipated impervious surface areas and compliance with stormwater management plans and Water Supply regulations are provided. 76-Unit Townhomes - The proposed 76-Unit townhome development west of Village Pond is anticipated to exceed 30% impervious surface or built upon area (BUA). However, we do not believe that additional stormwater devices should be required beyond the existing Village Pond because this development exists within the original boundaries of the Governors Village development previously approved and was included within the design of the Village Pond. It should be noted that if the drained pond wetland area (Impact #4) is permitted for impacts that there will be no additional waters located within the drainage area of this townhome development other than the "Village Pond". And as such there are no streams or other wetlands on the site that could be negatively impacted by stormwater runoff from the development. We have provided additional photos of the drained pond wetland area for your records. Additional photos of the Village Pond are provided for your records. The pond is functioning as designed. In addition, a fringe wetland has formed around the pond that will provide additional nutrient uptake and wildlife habitat. Governors Village Individual Permit Request / S&EC Project No. 05-9325.w1 July 29, 2005 Page 4 of 5 49-Lot Subdivision - The 49-lot residential subdivision has been recently added to the development and was not part of the original Governors Village. As such we believe that this new subdivision should comply with current DWQ stormwater management practices if the subdivision exceeds 30% BUA as typically required by DWQ and as required by many of the existing General Water Quality Certifications. The project engineer has calculated the anticipated BUA (see attached) and initially determined that this area would just barely exceed 30% BUA. As such the project manager has agreed to reduce the BUA of the development. Modifications such as reducing the width of the sidewalks to 4 feet and eliminating sidewalks in some areas where implemented to reduce the BUA below 30%. The details of the project engineer's calculations as well as typical lot footprints and a map of the project area are attached. The typical footprints include both front and rear loading garage plans consistent with existing homes built in earlier phases of Governors Park (an existing residential section of Governors Village). The project engineer used conservative, higher anticipated footprint of 3,730 square feet for all of the 49 lots, realizing that some lots will in fact be less impervious. The total BUA is now anticipated to be 29.8% and should therefore not require additional stormwater management devices beyond the existing Village Pond. Water Supply Compliance - The development does and will continue to comply with the locally implemented Water Supply Watershed ordinance as described in the letter from Chatham County dated April 29, 2005 and provided within the original application. This county ordinance was required under North Carolina Administrative Code 15A NCAC 02B .0104 and .0216 for Water Supply IV (WS-IV) waters. Please let us know ifyou require any additional information. However, we understand that the County is responsible for administering this program and as such we're not sure how much information to provide you. DWQ Approved Stormwater Management Plan - The 401 Water Quality Approval issued on October 18, 1996 stated; "Additional written DWQ approval is required for stormwater management for the commercial area." We have not been able to locate a copy this plan or written approval from the DWQ. A copy of the approval should exist within the DWQ file. However, we did not locate one while conducting a review of the DWQ file. Given the typical stormwater management devices that were required in 1996 (nine years ago) by the DWQ, we believe that the stormwater management plan most likely included the "Village Pond". Treeline - Wetland Impact Map #3 depicts a representation of a treeline different from what actually exists in the field. We apologize for this confusion. The actual treeline is located approximately along the wetland stream boundary along Davis Stone Drive up to the proposed road crossing to the 49-lot subdivision. The applicant is not proposing to clear this area other than that immediately within the sanitary sewer easement. This easement will comply with all of the standard conditions listed within the current GC3374 and NWP12 (even though the impacts are requested to be approved under this Individual Permit and Certification) and should therefore be considered a temporary impact. The proposed road crossing to the 49-lot subdivision was shifted south towards the Village Pond prior to the initial permit request to move it into an already primarily cleared area north of the Village Pond and to avoid impacts to the free-flowing portions of the stream. Governors Village Individual Permit Request / S&EC Project No. 05-9325.w1 July 29, 2005 Page 5 of 5 CONCLUSION It is our understanding that this additional information will provide you all of the information required for you to continue the review of our permit application. Please contact us if you require any information beyond what has been provided in this response. We appreciate your review and comments.

Would not align with David Stone Drive south of the townhomes, but rather "T" into the alley behind the townhomes. As such, we do not believe this alternative to be practical nor do we believe that this alternative will increase water quality benefits. Stormwater - Additional information regarding the anticipated impervious surface areas and compliance with stormwater management plans and Water Supply regulations are provided. 76-Unit Townhomes - The proposed 76-Unit townhome development west of Village Pond is anticipated to exceed 30% impervious surface or built upon area (BUA). However, we do not believe that additional stormwater devices should be required beyond the existing Village Pond because this development exists within the original boundaries of the Governors Village development previously approved and was included within the design of the Village Pond. It should be noted that if the drained pond wetland area (Impact #4) is permitted for impacts that there will be no additional waters located within the drainage area of this townhome development other than the "Village Pond And as such there are no streams or other wetlands on the site that could be negatively impacted by stormwater runoff from the development. We have provided additional photos of the drained pond wetland area for your records. Additional photos of the Village Pond are provided for your records. The pond is functioning as designed. In addition, a fringe wetland has formed around the pond that will provide additional nutrient uptake and wildlife habitat. Governors Village Individual Permit Request / S&EC Project No. 05-9325.w1 July 29, 2005 Page 4 of 5 49-Lot Subdivision - The 49-lot residential subdivision has been recently added to the development and was not part of the original Governors Village. As such we believe that this new subdivision should comply with current DWQ stormwater management practices if the subdivision exceeds 30% BUA as typically required by DWQ and as required by many of the existing General Water Quality Certifications. The project engineer has calculated the anticipated BUA (see attached) and initially determined that this area would just barely exceed 30% BUA. As such the project manager has agreed to reduce the BUA of the development. Modifications such as reducing the width of the sidewalks to 4 feet and eliminating sidewalks in some areas where implemented to reduce the BUA below 30%. The details of the project engineer's calculations as well as typical lot footprints and a map of the project area are attached. The typical footprints include both front and rear loading garage plans consistent with existing homes built in earlier phases of Governors Park (an existing residential section of Governors Village). The project engineer used conservative, higher anticipated footprint of 3,730 square feet for all of the 49 lots, realizing that some lots will in fact be less impervious. The total BUA is now anticipated to be 29.8% and should therefore not require additional stonmwater management devices beyond the existing Village Pond. Water Supply Compliance - The development does and will continue to comply with the locally implemented Water Supply Watershed ordinance as described in the letter from Chatham County dated April 29, 2005 and provided within the original application. This county ordinance was required under North Carolina Administrative Code 15A NCAC 02B .0104 and .0216 for Water Supply IV (WS-IV) waters. Please let us know if you require any additional information. However, we understand that the County is responsible for administering this program and as such we're not sure how much information to provide you. DWQ Approved Stormwater Management Plan - The 401 Water Quality Approval issued on October 18, 1996 stated; "Additional written DWQ approval is required for stormwater management for the commercial area." We have not been able to locate a copy this plan or written approval from the DWQ. A copy of the approval should exist within the DWQ file. However, we did not locate one while conducting a review of the DWQ file. Given the typical stormwater management devices that were required in 1996 (nine years ago) by the DWQ, we believe that the stormwater management plan most likely included the "Village Pond". Treeline - Wetland Impact Map #3 depicts a representation of a treeline different from what actually exists in the field. We apologize for this confusion. The actual treeline is located approximately along the wetland stream boundary along Davis, Stone Drive up to the proposed road crossing to the 49-lot subdivision. The applicant is not proposing to clear this area other than that immediately within the sanitary sewer easement. This easement will comply with all of the standard conditions listed within the current GC3374 and NWP12 (even though the impacts are requested to be approved under this Individual Permit and Certification) and should therefore be considered a temporary impact. The proposed road crossing to the 49-lot subdivision was shifted south towards the Village Pond prior to the initial permit request to move it into an already primarily cleared area north of the Village Pond and to avoid impacts to the free-flowing portions of the stream.

Erosion and sediment control practices must be in full compliance with all specifications governing the proper design, installation and operation and maintenance of such Best Management Practices in order to protect surface waters standards: a. The erosion and sediment control measures for the project must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Sediment and Erosion Control Planning and Design Manual. b. The design, installation, operation, and maintenance of the sediment and erosion control measures must be such that they equal, or exceed, the requirements specified in the most recent version of the North Carolina Sediment and Erosion Control Manual. The devices shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects, including contractor-owned or leased borrow pits associated with the project. c. For borrow pit sites, the erosion and sediment control measures must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Surface Mining Manual. d. The reclamation measures and implementation must comply with the reclamation in accordance with the requirements of the Sedimentation Pollution Control Act. e. Sufficient materials required for stabilization and/or repair of erosion control measures and stormwater routing and treatment shall be on site at all times. 3. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the impacts depicted in the 404/401Permit Application. All construction activities, including the design, installation, operation, and maintenance of sediment and erosion control Best Management Practices, shall be performed so that no violations of state water quality standards, statutes, or rules occur, 4. Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored within six months of the date that the Division of Land Resources has released the project; Continuing Compliance: 5. Mr. Dan Vincent and/or Governors Club Limited Partnership shall conduct construction activities in a manner consistent with State water quality standards (including any requirements resulting from compliance with section 303(d) of the Clean Water Act) and any other appropriate requirements of State law and federal law. If the Division determines that such standards or laws are not being met (including the failure to sustain a designated or achieved use) or that State or federal law is being violated, or that further conditions are necessary to assure compliance, the Division may reevaluate and modify this Certification to include conditions appropriate to assure compliance with such standards and requirements in accordance with 15A NCAC 2H.0507(d). Before modifying the Certification, the Division shall notify Mr. Dan Vincent and/or Governors Club Limited Partnership and the US Army Corps of Engineers, provide public notice in accordance with 15A NCAC 2H.0503 and provide opportunity for public hearing in accordance with 15A NCAC 2H.0504. Any new or revised conditions shall be provided to Mr. Dan Vincent and/or Governors Club Limited Partnership in writing, shall be provided to the United States Army Corps of Engineers for reference in any Permit issued pursuant to Section 404 of the Clean Water Act, and shall also become conditions of the 404 Permit for the project; Mr. Dan Vincent, Governors Club Limited Partnership Page 4 of 5 October 3, 2005 Road Crossings: 6. Culvert Installation Culverts required for this project shall be installed in such a manner that the original stream profiles are not altered. Existing stream dimensions (including the cross section dimensions, pattern, and longitudinal profile) must be maintained above and below locations of each culvert. Culverts shall be designed and installed to allow for aquatic life movement as well as to prevent head cutting of the streams. If any of the existing pipes are or become perched, the appropriate stream grade shall be re- established or, if the pipes installed in a perched manner, the pipes shall be removed and re-installed correctly. The establishment of native, woody vegetation and other soft stream bank stabilization techniques must be used where practicable instead of riprap or other bank hardening methods. If riprap is necessary, it shall not be placed in the streambed, unless specifically approved by the Division of Water Quality. Installation of culverts in wetlands must ensure continuity of water movement and be designed to adequately accommodate high water or flood conditions. Stormwater Management: 7. Since the project is located in a WS-IV, Nutrient Sensitive Waters, it will be required that within 60 days of the issuance of this Certification, a final, written stormwater management plan (including a signed and notarized Operation and Maintenance Agreement) for the 76-Unit Townhomes (proposed developed area west of Village Pond) and the 49-Lot residential subdivision (proposed developed area east of the Village Pond) shall be approved in writing by the Division of Water Quality's Wetlands Unit. The facilities must be designed to remove 85% TSS, as well as treat nitrogen in the runoff from each area by using extended detention wetlands, bio- retention areas, and/or ponds followed by forested filter strips (designed according to latest version of the NC DENR Stormwater Best Management Practices Manual). Also, before any permanent building or other structure is occupied in each area, the facilities (as approved by the Wetlands Unit) for that area shall be constructed and operational, and the stormwater management plans for these areas (as approved by the Wetlands Unit) shall be implemented. The structural stormwater practices as approved by the Wetlands Unit as well as drainage patterns must be maintained in perpetuity. No changes to the structural stormwater practices shall be made without written authorization from the Division of Water Quality. However, in an effort to be accommodating to what may be unique site specific constraints DWQ will accept an equivalent amount of presently untreated onsite stormwater to offset the new impervious surface that is being proposed to occur with these project areas (Our hope is that this would be easier site specific constraints). Other conditions: 8. Certificate of Completion Upon completion of the project, the Applicant shall complete and return the enclosed "Certificate of Completion" form to notify NCDWQ when all work included in the §401 Certification has been completed. The responsible party shall complete the attached form and return it to the 40I/Wetlands Unit of the NC Division of Water Quality upon completion of the project. Please send photographs upstream and downstream of each culvert site to document correct installation along with the Certificate of Completion form. Mr. Dan Vincent, Governors Club Limited Partnership Page 5 of 5 October 3, 2005 9. Protective Fencing The outside buffer, wetland or water boundary and along the construction corridor within these boundaries approved under this authorization shall be clearly marked with orange warning fencing (or similar high visibility material) for the areas that have been approved to infringe within the buffer, wetland or water prior to any land disturbing activities to ensure compliance. 10. Construction Stormwater Permit NCG010000 Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of Land Resources (DLR) or a DLR delegated local erosion and sedimentation control program, an NPDES General stormwater permit (NCG010000) administered by DWQ is automatically issued to the project. This General Permit allows stormwater to be discharged during land disturbing construction activities as stipulated by conditions in the permit. If your project is covered by this permit (applicable to construction projects that disturb one (1) or more acres], full compliance with permit conditions including the sedimentation control plan, self-monitoring, record keeping and reporting requirements are required. A copy of this permit and monitoring report forms may be found at httt -11h2o.enr.state.nc.us1su1Forms Documents.htm. 11. Deed Notifications Deed notifications or similar mechanisms shall be placed on all retained jurisdictional wetlands, waters and protective buffers in order to assure compliance for future wetland, water and buffer impact. These mechanisms shall be put in place prior to impacting any wetlands, waters and/or buffers approved for impact under this Certification Approval and Authorization Certificate. A sample deed notification can be downloaded from the 401/Wetlands Unit web site at http://h2o.enr.state.ne.us/newetlands. The text of the sample deed notification may be modified as appropriate to suit to this project. Also, this approval to proceed with your proposed impacts or to conduct impacts to waters as depicted in your application shall expire upon expiration of the 404 Permit. If this Certification is unacceptable to you, you have the right to an adjudicatory hearing upon written request within sixty (60) days following receipt of this Certification. This request must be in the form of a written petition conforming to Chapter 150B of the North Carolina General Statutes and filed with the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. If modifications are made to an original Certification, you have the right to an adjudicatory hearing on the modifications upon written request within sixty (60) days following receipt of the Certification. Unless such demands are made, this Certification shall be final and binding. This the 3rd day of October 2005 DIVISION OF WATER QUALITY Alan W. Klimek, P.E. AWK/dae AGovemors Village l.'

The problematic condition is Condition 7, which requires that a stormwater management plan be submitted for approval by DWQ and implemented which achieves 85% TSS removal and nitrogen treatment for two parcels being newly developed and that extended detention wetlands, bioretention areas, or ponds followed by filter strips be utilized. However, the last sentence of Condition 7 recognized that site constraints might (in fact, do) make it impossible to achieve these stormwater requirements without significantly altering the site plans and restructuring the transaction. Condition 7 therefore allows the developer, in lieu of the requirements just stated, to achieve comparable treatment to stormwater from other parts of the development. We would like to submit a stormwater plan that demonstrates that the existing stormwater pond serving the entire development can, with relatively minor modifications (raising the outlet and adding a littoral shelf), meet 85% TSS removal, for the entire project, not just the newly developed parcels. I think we can further demonstrate significant nitrogen treatment for entire development, though some modifications (e.g., addition of a forebay) might be needed if we have to provide additional nitrogen treatment. We would like to meet with you on site to show you our conceptual plan for stormwater management. We will then submit a formal plan with detailed engineering drawings. Since this type of submittal is envisioned and allowed by the existing 401, I don't think any modification to the 401 is required. Please let me know some times next week that work for you. We would like to get this done ASAP as we are on a tight construction schedule. Thanks for your help. Steve El Steven J.

Since our last submittal on August 5th, I've been reporting in that the agencies are still reviewing the latest information. I've been in your shoes and realize that it has only been a month, but every week they get more anxious. My fear is that they will eventually start thinking that it's a matter of my persistence and abilities in getting a response out of the agencies and not simply a matter of your work loads. If this happens then I expect that they will start looking to bring in assistance from other sources.

Specific plans and location information are described below and shown on the attached plans. This Public Notice and all attached plans are also available on the Wilmington District Web Site at www.saw.usace.army.mil/wetlands Applicant: Governors Club Limited Partnership Attn: Mr. Dan Vincent Post Office Box 3923 Sanford, NC 27331 AGENT (if applicable): Authority Soil & Environmental Consultants, PA Attn: Mr. Bob Zarzecki 11010 Raven Ridge Road Raleigh, North Carolina 27614 The Corps will evaluate this application and a decide whether to issue, conditionally issue, or deny the proposed work pursuant to the applicable procedures of Section 404 of the Clean Water Act. Location The project is located in Governors Village Subdivision, east of Mt. Carmel Church Road, north of Old Farrington Road, southeast of Chapel Hill, Chatham County, North Carolina. The site contains wetlands and unnamed tributaries to Cub Creek, in the Cape Fear River Basin (8-Digit Cataloging Unit 03030002). Coordinates (in decimal degrees) for the site are 35.8509 'N, 79.0246 ° W. Existing Site Conditions The subdivision, which is located in a suburban area south of Durham, has been under development for several years. Currently, northern and western portions of the property contain single and multi-family residential units or commercial space. The southern portion of the project contains several forested tracts and a large stormwater pond originally constructed to treat storrwater runoff from the entire site. Two stream channels flow into the upper (northern) end of the pond from existing portions of the development. Both stream channels receive considerable runoff from completed portions of the development. A small drained pond, which now contains an herbaceous wetland, is also located in a forested area to the west of the stormwater pond. Applicant's Stated Purpose As stated by the applicant, the purpose of the project is to complete construction of Governors Village, and to provide retail, office, and other commercial services and housing for residents within the surrounding community. Project Description The permit request for this project is an after-the-fact application. Some of the impacts associated with this permit application have already been completed. This public notice does not imply, on the part of the Corps of Engineers or other agencies, either a favorable or an unfavorable opinion of the work performed. This notice is issued to solicit comments regarding the factors on which a final decision will be based. The applicant has agreed to place the project on hold, pending the resolution of the permit application. Further enforcement action, including possible legal action, has been suspended pending the outcome of this consideration. The project is a mixed-use development that includes residential and commercial areas. Development of the site began in the mid-1990's and has progressed from the northern portion of the site to the south. During the initial stages of the project, the Corps provided permit authorization for all existing and proposed impacts, however the authorization expired before all impacts could be completed. One of the road crossings, shown on Impact Map 2 in the attached plans, was constructed after the permit authorization expired. The applicant is applying for reauthorization for this unauthorized road crossing and for all remaining unfinished impacts. As stated by the applicant, there are several remaining impacts to waters of the U.S. needed for completion of the project. Additional construction is planned to expand the existing commercial portion of the site to allow two additional buildings and parking areas. The work, as depicted on Impact Map 1, will require the placement of concrete culverts, fill material, and riprap into 0.118 acre of wetlands. The applicant also proposes to extend utility services across the stream system downstream of the commercial site. These impacts, shown on Impact Map 2, will temporarily disturb of 0.012 acre of wetlands and 20 linear feet of perennial stream channel. Map 2 also shows the road crossing that was constructed to provide access between residential and commercial portions of the site. This road was constructed without permit authorization and has resulted in the placement of culverts and fill into 148 linear feet of perennial stream channel. A second road crossing is planned to provide access between the existing residential areas and an undeveloped tract that will contain 49 single-family residential lots. This road crossing, as shown on Impact Map 3, will require the placement of 2 culverts and fill into 0.041 acre of open water which was formed by the back water of the storm pond extending up one of the tributaries. Map 3 also depicts the temporary disturbance of 0.022 acre of wetland and 34 linear feet of intermittent stream channel for the construction of utility lines required to service the new single-family residential area. The final impact will result from the placement of 0.213 acre of fill material into herbaceous wetlands located in the bed of the drained pond. These impacts, which are depicted on Impact Map 4, are necessary for the construction a new 76-unit town home cluster. Heavy equipment, including graders, pan scrapers, excavators, bull dozers, etc. will be used for the construction of the project. Impacts to wetlands associated with all proposed activities totals 0.365 acre, including 0.034 acre of temporary disturbance. Impacts to stream channels associated with all proposed activities totals 202 linear feet, including 54 linear feet of temporary disturbance. The total loss of all waters of the U.S. is 0.425 acre. The applicant proposes mitigation for impacts to stream channels and wetlands associated with the project at a 1:1 ratio by providing payment into the North Carolina Ecosystem Enhancement Program for the restoration of 148 linear feet of stream channel, 0.365 acre of riparian wetlands. No mitigation for impacts to open waters has been proposed. Other Required Authorizations This notice and all applicable application materials are being forwarded to the appropriate State agencies for review. The Corps will generally not make a final permit decision until the North Carolina Division of Water Quality (NCDWQ) issues, denies, or waives State certification required by Section 401 of the Clean Water Act (PL 92-500). The receipt of the application and this public notice in the NCDWQ Central Office in Raleigh serves as application to the NCDWQ for certification. A waiver will be deemed to occur if the NCDWQ fails to act on this request for certification within sixty days of the date of the receipt of this notice in the NCDWQ Central Office. Additional information regarding the Clean Water Act certification maybe reviewed at the NCDWQ Central Office, 401 Oversight and Express Permits Unit, 2321 Crabtree Boulevard, Raleigh, North Carolina 27604-2260.

The project site is located east of Mt. Carmel Church Road and north of Old Farrington Road, southeast of Chapel Hill, Chatham County, North Carolina. The site contains wetlands and unnamed tributaries to Cub Creek, in the Cape Fear River Basin After review of your proposal, the U.S. Fish and Wildlife Service (USFWS) provided comments by letter dated June 10, 2005 (copy enclosed). The letter states that they are concerned about the lack of on-site mitigation and recommends that remaining streams and wetlands be placed in a perpetual conservation easement for the life of the project. The letter also states that the proposed mitigation ratio is inadequate to compensate for the loss of natural functions and values associated with the impacted streams and wetlands, and recommends that a minimum ratio of 2:1 be required. A comment letter was also received from the North Carolina Wildlife Resources Commission dated June 15, 2005 (copy enclosed). The letter recommends several permit conditions, including the preservation of remaining jurisdictional areas on site. Comments were also received from an adjacent landowner by letter dated June 15, 2005 (copy enclosed). The letter raises concerns regarding the effects of continued commercial and residential growth in the area, including the impact of fertilizers on drinking water and the loss of wetland areas. We are forwarding copies of all letters for your review and consideration, and request that you respond to this office, in writing, on or before July 21, 2005. Should you have any further questions related to these comments or your DA permit application for this project, please contact me at 919-876-8441, extension 26. Sincerely, Todd J.

This report is submitted in accordance with the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.&C. 661-667d); to be used in your determination of compliance with 404(b)(1) guidelines (40 CFR 230) and'in your public interest review (33 CFR 320.4) relative to the protection of fish and wildlife resources. The proposed project is located in the Governors Village Subdivision east of Mt. Carmel Church Road and north of Old Farrington Road, southeast of Chapel Hill. According to the Public Notice, the site is located in a suburban area south of Durham and has been under development for several years. Currently, northern and western portions of the property contain single and multi-'family units or commercial space. The southern portion of the project site contains several forested areas and a large stormwater pond constructed to treat stormwater leaving the site. Two stream channels flow into the pond from existing portions of the development and both receive considerable runoff from the site. As stated by the applicant ii1C purpose of the project is to complete construction of a residential development, and to provide office, retail and other commercial services for residents in the surrounding community. This permit request is for after-the-fact authorization to impact streams and wetlands associated with a partially completed development. Many of the impacts to waters of the U.S, natural areas, and associated wetlands have already occurred. The project is a mixed use development that includes residential and commercial areas. Development of the site began in the mid 1990's and has progressed from the northern portions of the property to the south. During initial stages of the project, the Corps provided permit authorization for all existing and proposed impacts, however, the authorization expired before all impacts could be completed. The applicant is applying for reauthorization for an unauthorized road crossing and all remaining unfinished impacts. Impacts to wetlands associated with the proposed development total 0.365 acres, including 0.034 acres of temporary impacts. Impacts to stream channels associated with the proposed activity total 202 linear feet, including 54 linear feet of temporary impacts. The total loss of all waters of the U.S. is 0.425 acres. The applicant proposes mitigation for the proposed loss of natural areas, streams and wetlands by payment into the North Carolina Ecosystem Enhancement Program (EEP) in the amount necessary to restore 148 linear feet of perennial stream channel, and 0.367 acres of riparian wetlands. The applicant has proposed a mitigation ratio of 1:1, however, no mitigation for the conversion of open waters is proposed. The project would involve extensive clearing, grading, excavation, and fill for the construction of lots, homes, roads, stormwater facilities and associated infrastructure. Impacts would result from the placement of fill material, culverts and rip rap, and applicant has not proposed any on-site mitigation for the proposed impacts to streams, wetlands, and riparian areas. The stream, wetlands and natural areas proposed to be impacted by the project provide important ecological and hydrological functions for the receiving waters of Cub Creek and ultimately B. Everett Jordan Lake. The increase in the amount of impervious surface will alter the character of stormwater runoff leaving the site, and if untreated, this runoff could have an adverse affect on the quality of aquatic habitats that receive water from the project site. The Service is concerned about the indirect and cumulative impacts of multiple phase projects requiring multiple federal section 404:permits, particularly for impacts to natural systems that have already occurred. We are also concerned about the lack of on-site mitigation for proposed impacts to these natural areas and recommend that the applicant place any remaining wetlands or streams on the site in a perpetual conservation easement for the life of the project to protect the remaining ecological functions of these natural areas. Appropriate erosion and sediment controls should be required for all aspects of the project to protect adjacent aquatic habitats as a condition of any section 404 permit for the proposed project, and these measures should be aggressively implemented and maintained to prevent the transport of sediment to adjacent streams, wetlands and natural areas. Additionally, we find that the proposed mitigation ratio of 1:1 is inadequate to compensate for the loss of natural functions and values associated with the proposed impacts to streams and wetlands. The mitigation required for this project should be increased from the proposed amount to a minimum of 2:1 to compensate for the natural functions lost due to permanent impacts to streams and wetlands subject to section 404 of the Clean Water Act. In order to affect fish and wildlife conservation and to fulfill the public trust stewardship obligations in this matter, the Service recommends that remaining wetlands and streams on the site be placed under permanent protective instruments for the life of the project. Additionally, appropriate stormwater treatment, and sediment controls are a necessary condition for this project to protect the aquatic life and water quality of the receiving streams downstream of this development. We also recommend that additional mitigation be required to adequately compensate for the permanent loss of streams and wetlands associated with the project. If you have any questions regarding this information, please contact Mr. Mark D. Bowers of my staff at (919) 8564520 (Ext. 19) or at the above address.

Hamilton, Executive Director MEMORANDUM TO: Mr. Todd Tugwell, Raleigh Regulatory Field Office U.S. y Corps of Engineers FROM: Shan L. Bryant, Piedm nt Region Coordinator Habitat Conservation Program DATE: 15 June 2005 SUBJECT: Public Notice for Governors Club Limited Partnership for Construction of Governors Village Subdivision (After-the-Fact), Chatham County, North Carolina. Action 1D No. 200520149 Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed the subject document and we are familiar with the habitat values of the area. Our comments are provided in accordance with provisions of the Clean Water Act of 1977 (as amended), Fish and Wildlife Coordination Act '(48 Stat. 401, as amended,; 16 U.S.C. 661-667d? and North Carolina General Statutes (G.S. 113-131 et seq-). The project is a mixed use development including single and mufti-family residential units and commercial space. Two stream channels now through the site into a large stormwater pond. The applicant had received permit authorization for all existing and proposed impacts. However, the authorization expired before all impacts were completed. One of the road crossings was constructed after permit authorization expired. The applicant is applying for reauthorization for the unauthorized road crossing and all remaining impacts. Proposed impacts to stream channels resulting from placement of fill material, culverts, rip rap and/or utility lines totals 202 linear feet, including 54 linear feet of temporary impact. Proposed impacts to wetlands resulting from the placement of culverts, fill material, rip rap, and utility lines totals 0.365 acre including 0.034 acre of temporary impact. The applicant proposes 1:1 mitigation for impacts to stream channels and wetlands associated with the project by providing payment into the North Carolina Ecosystem Enhancement Program (NCEEP) for the restoration of 148 linear feet of stream channel and 0.365 acre riparian wetlands. No mitigation for impacts to open waters has been proposed. Unnamed tributaries to Cub Creek flow through the site. Cub Creek is a headwater tributary to the upper New Hope Creek arm of B.E. Jordan Reservoir in the Cape Fear River basin. The upper New Hope Creek arm of B.E. Jordan Reservoir is on the State's 303(d) list of impaired waters. There are records for the federal and state threatened bald eagle (Haliaeetus leucocephalus) near the project site. Mailing Address: Division of Inland Fisheries - 1721 Mail Service Center - Raleigh, NC 27699-1721 Telephone: (919) 733-3633 - Fax: (919) 715-7643 z'd SZ9G-Ebb-9EE -4ueiRug -1'S eSl-:6o SO ST unr Page 2 15 June 2005 Governor's Village Action ID No. 200520149 Additionally, B.E. Jordan Reservoir supports a diverse fishery including largemouth bass (Micropterus salmoides), crappie (Pomoxis spp_), sunfish (Lepomis spp.), catfish (Ictalurus spp.) and striped bass (Moron s=atilis). We hesitate to concur with the piping of stream channels due to the potential for long-term.and cumulative impacts. Stream pipingand placing fill in aquatic resources can result in significant negative impacts to downstream areas and eliminate fish and wildlife habitat. Stream piping reduces the infiltration of stormwater and associated pollutants, as well as the dissipation'of stream energy. Piping a stream and placing it underground removes both aquatic and terrestrial habitat. Piping a stream channel and filling the wetlands will alter the hydrology of the existing channel. and eliminate beneficial functions. Likewise we hesitate to concur with the filling of wetlands due to their wildlife habitat value and the well- known beneficial functions that they provide for flood control and water quality protection.. Changes in land use from a primarily forested area to an urban landscape may exacerbate channel degradation and sediment impacts to stream ecosystems due to increased stormwater runoff. Multiple studies have shown that stream degradation occurs at 10% impervious (Schueler 1994; Arnold and Gibbons 1996; Doll et al. 2000; Mallin et al. 2000; May and Homer 2000; Stewart et al. 2000; Paul and Meyer 2001). Since the applicant had previous permit authorization for the proposed impacts, we will not object to the project provided the following conditions are incorporated into the permit to further reduce. impacts to fish and wildlife resources. 1. To minimize additional stream impacts, while retaining some measure of wildlife habitat, we recommend that a I00-foot undisturbed, native, forested buffer along perennial streams, and a 50- foot buffer along intermittent streams and wetlands. Maintaining undisturbed, forested buffers along these areas will minimize impacts to fish and wildlife resources, water quality,: and aquatic habitat both within and downstream of the project area- In addition, wide riparian buffers are helpful in maintaining stability of stream banks and for treatment of pollutants associated with stormwater runoff. Whereas, a grassed buffer, particularly fescue, is a vegetated buffer. but will not provide the necessary and highly valuable functions as discussed for forested buffers. 2. We recommend that all remaining wetlands and streams on the site should be protected from additional impacts by placing them in a permanent conservation easement to prohibit filling, draining, flooding, and excavation. 3. Use bridges for all permanent roadway crossings of streams aid associated wetlands to eliminate the need to fill and culvert, where practicable. If culverts must be used, the culvert should be designed to allow passage of aquatic organisms. Generally, this means that the culvert or pipe invert is buried at least one foot below the natural streambed. If multiple cells are required, the second and/or third cells should be placed so that their bottoms are at stream bankfull stage. This will allow sufficient water depth in the culvert or pipe during normal flows to accommodate movements of aquatic organisms. If culverts are long and sufficient slope exists, baffle systems are recommended to trap gravel and provide resting areas for fish and other aquatic organisms. If multiple pipes or cells are used, at least one pipe or box should be designed to remain dry during normal flows to allow for wildlife passage. In addition, culverts or pipes should be situated so that no channel realignment or widening is required. Widening of the stream channel at the inlet or outlet of structures usually causes a decrease in water velocity causing sediment deposition that will require future maintenance. Finally, riprap should not be placed on the streambed. 4. To adequately protect streams, it is suggested that impervious surface is limited to less than 10%0_ Suggested examples to accomplish the <10% impervious goal are using conventional designs at a c C7QJ _a4_4._QVf.1 -%III-a_1Q •1 Ol.T - Page 3 15 June 2005 Governor's Village Action ID No. 200520149 level of <10% imperviousness or using conservation clusters with higher densities, with dedicated open space and other stormwater control measures to mimic the hydrograph consistent with an impervious coverage of less than 10%. 5. Locate sewers and other utilities as far away from creeks as functionally possible and minimize stream crossings. It is preferable that sewers be located outside the riparian buffers. The directional bore (installation of utilities beneath the riverbed, avoiding impacts to the stream and buffer) stream crossing method should be used for utility crossings wherever practicable, and the open cut stream crossing method should only be used when water level is low and stream flow is minimal. Manholes or similar access structures should not be allowed within buffer areas. Stream crossings should be near perpendicular (75° to 105' ) to stream flow and should be monitored at least every three months for maintenance needs during the first 24 months of the project and then annually thereafter. Further, pesticides (including insecticides and herbicides) should not be used for maintenance of rights-of-way within 100 feet of perennial streams and 50 feet of intermittent streams, or within floodplains and wetlands associated with these streams. 6. We recommend that landscaping consist of non-invasive native species and LID technology. Using native species instead of ornamentals should provide benefits by reducing the need for fertilizers, herbicides, and pesticides. Additionally, native species should require less water. Using LID technology in landscaping will not only help maintain the predevelopment hydrologic regime, but also enhance the aesthetic and habitat value of the site. 7. Specialized efforts and techniques are implemented to reduce sediment runoff from construction activities. Excessive silt and-sediment loads can. have numerous detrimental'effects on aquatic resources including destruction of spawning habitat, suffocation of eggs, and clogging of gills of aquatic species. It is our understanding that compensatory mitigation for wetlands is 2:1 for restoration, 3:1 for creation, 4:1 for enhancement and 10:1 for preservation (in combination with appropriate restoration, creation and enhancement). Therefore, we feel that compensatory mitigation for impact to wetlands should be 2:1. Thank you for the opportunity to comment on this project.

To fully understand the impact of the permit request, we cannot do so based on this letter alone. However, we will submit the following observations: Increased number of residential and commercial buildings identified on your enclosed materials (Maps AID #200520149 sheets 4-7, clearly is impacting clean water. (See Notice from Chatham County Water System enclosed). Owners (commercial and residential) continue to use massive amounts of fertilizers to beautify their lawns and gardens. The materials end of washing into the creek identified on Maps AID #200520149 Sheet 2 and into Jordan Lake and eventually into our drinking water. The developer needs to provide alternative methods to avoid wetland loss such as allowing more open space. The ground water is effected not only by the construction equipment identified on page 2 "Project Description" and page 3, but on the area as a whole once homes are erected. It is inevitable growth will occur but developers and government must implement and adhere to a "Smart Growth" plan to protect wetlands in the county and throughout our neighborhoods. Thank you for your prompt attention in this matter. Sincerely, k.'IC'Llohfaenter Enclosure IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER CHATHAM COUNTY WATER SYSTEM Has Not Met Monitoring Requirements We are required to monitor your drinking water for specific contaminants on a regular basis. Results of regular monitoring are an indicator of whether or not our drinking water meets health standards.

Currently, we have fully staffed and trained personnel on the proper way to collect samples. Samples are now being collected in a timely manner and currently in compliance. These problems have now been corrected. To ensure the control of disinfection by-products, we have done a progressive flushing program as well as increased monitoring.

My only real comment involves maybe getting them to look hard at some on-site mitigation for the unpermitted stream crossing. I know we are going to ask them for alternatives to this crossing, even though it is existing (I think we all agreed that the angle of the crossing would not have been permitted). Although there probably isn't much left on the site that is not planned to be "protected", except for the small area in the former pond footprint (Impact Area #4).

GOVERNORS VILLAGE BLOCK SHEETS BLOCK 18 - Nature of Activity The project involves the completion of development of Governors Village mixed-use commercial and residential subdivision located in northern Chatham County, NC. As described further in Block 23, much of the development has already been completed. Construction of Governors Village began in the mid-1990s. Approvals have been received by both the U.S. Army Corps of Engineers (USACE; Action ID 199503160 and 199600078) and the N.C. Division of Water Quality (DWQ; Project No. 96-0392 and 96- 0884). No additional impacts to waters beyond those previously approved or requested within this application are anticipated at this time. The applicant is requesting approval to impact waters for an existing road crossing (see Impact Map #2 and the USACE Notification of Unauthorized Activity provided in the attached Prior Project History section of this application). In addition to this road crossing the applicant is requesting approval to impact wetlands and waters for the construction of one additional road crossing (see Impact Map #3), utility crossings and lot fill. Many of these impacts were previously approved, but they have not yet occurred and the previous approvals have expired. These activities and the dimensions of the structures are illustrated in the attached "Impact Maps". The materials to be used include earthen fill to construct the base for the roads and lots. ' The roads and parking areas will be paved and use curb and gutter to manage stormwater runoff. Paving materials include asphalt and concrete. Curb and gutter materials include concrete metal drop inlets and reinforced concrete pipes (RCP). The existing road ' crossing (see Impact Map #2) was constructed using twin 42" RCPs (see Site Photo). The proposed second crossing (see Impact Map#3) will be installed using a single 54" RCP. The residential structures both already built and proposed include stick-built ' single-family homes and townhomes with concrete driveways and walks. The commercial buildings are constructed of typical commercial building materials including primarily steel, concrete block, brick and glass. The previously approved and constructed pond commonly referred to as the "Village Pond" is a large, stormwater management pond required by the County to meet the Chatham County Water Supply watershed stormwater requirements for Governors Village (see attached letter from Chatham County dated April 29, 2005 provided within the attached Prior Project History section of this application). Stormwater runoff from Governors Village (including the proposed development areas not currently constructed) drain to and are managed by this pond. GOVERNORS VILLAGE ' BLOCK SHEETS ' BLOCK 19 - Project Purpose ' Project Purpose: The purpose of this project is to complete construction of development of Governors Village, a mixed-use commercial and residential development located between Mt. Carmel Church Road, Whipporwill Lane and Old Farrington Road in northern Chatham ' County, NC. There are basically three properties that have not been developed within Governors Village. The properties north and west of the "Village Pond" were previously approved by the USACE and DWQ for impacts to wetlands and waters. The property ' east of the "Village Pond" was added to Governors Village this spring. No jurisdictional wetlands or waters are proposed to be impacted on this property other than the road crossing impacts (see Impact Map #3) to connect this property to the rest of Governors ' Village. Properties to the south of the "Village Pond" are not part of Governors Village and consist of existing residential properties. ' Project Need: Governors Village provides retail, office, other commercial services and housing for residents within the surrounding community as well as existing and future residents within Governors Village. This development helps to address service and housing needs of the community's growing population. I GOVERNORS VILLAGE BLOCK SHEETS BLOCK 20 - Reasons for Discharge Proposed Commercial / Retail Area - The wetland impact proposed on Impact Map #I is required to complete construction of the commercial / retail section of Governors Village previously planned for the development in the mid-1990s. These impacts were previously approved by both the USACE and DWQ (see the Prior Project History section attached to this application). Existing Road Crossing - The existing road crossing (see Impact Map #2) was required to provide a second access for the existing townhomes north of the "Village Pond". The crossing not along improves traffic flow through Governors Village, it also provides for multiple points of ingress and egress in case of any emergency. Proposed Second Crossing - The proposed second crossing (see Impact Map #3) is required to connect the new 49-lot single-family residential subdivision east of "Village Pond" to the remainder of Governors Village. Without this crossing the residents of this community would need to utilize existing state roads (Old Farrington Road, etc.) and at least one intersection of state roads just to drive from their home to the retail area of Governors Village. This is not only twice the distance it will also lead to unnecessary traffic congestion on these state roads. In addition to connecting the subdivision to the remainder of Governors Village, this crossing will provide a second point of ingress and egress for the community. Proposed Townhomes - The wetland impact proposed on Impact Map #4 is to fill ' wetlands within a drained pond bottom to allow for the construction of residential townhomes west of the "Village Pond". This property (previously known as the Dossett Parcel) has recently been approved by Chatham County for the construction of 76 ' townhomes from the previously approved commercial / office development. The wetland area has a surface connection to the "Village Pond" via a channel that is not depicted on either the USGS topographic map or Chatham County Soil Survey. The channel was determined by S&EC staff to be an ephemeral ditch below the wetland / drained pond ' and above the existing walking trail around the "Village Pond". The applicant does not dispute the jurisdiction of this wetland area or it's determination as non-isolated. However it should be noted that S&EC staff do not believe that this original pond in this ' location was constructed on either an intermittent or perennial stream. The quality and functions of this wetland area are low compared to other wetland systems. ' Utilities - Impacts to wetlands and waters for utility crossings are also proposed on Impact Maps #2 and #3. These impacts are required to provide utility services to development areas described within this application. t GOVERNORS VILLAGE BLOCK SHEETS BLOCK 21 - Type of Material Being Discharged and the Amount of Each Type in Cubic Yards WETLAND IMPACT TABLE Wetland Impact Type Type of Area of Volume of Site Number Type of Impact (e.g., fores forested marsh Material Impact Discharge indicate on ( , , , herbaceous, bog, etc.) Bein Bein (sq yds.)

Existing Conditions: The project involves the completion of the development of the Governors Village ' residential and commercial mixed-use development located on Mt. Carmel Church Road (SR 1008) in Chatham County, NC. A large portion of the development has already been constructed, residential and commercial lots have been sold, buildings and homes have ' been constructed, and businesses and residents are occupying their buildings and homes. The road / driveway crossing depicted on Impact Map #2 has already been constructed. ' The owner believed that all appropriate 404 and 401 approvals had been received at the time the road was constructed. However, the owner was notified in a letter dated December 27, 2004 from Mr. Todd Tugwell of the U.S. Army Corps of Engineers (USACE) that this activity was not authorized (Action ID 200520149). The USACE and ' DWQ previously authorized impacts to these waters as described in the attached Prior Project History. Although as Mr. Tugwell explains in his letter, the permit had expired prior to construction of the roadway, and the plans have been modified from the ' originally proposed plans. The additional impacts proposed within this application have not yet been constructed. Dredged or Fill Material Already Discharged: ' The activities within Waters of the U.S. that have already occurred include the discharge of fill into wetlands and other waters for the development of roads, utilities, and commercial and residential lots. Waters have also been impacted by both fill and ' flooding for the construction of the stormwater management pond. ' Previous Agency Involvement & Approvals: Please refer to the attached Prior Project History for additional information and reference materials. Approvals have been received from the DWQ (DWQ Project No.(s) 96-0362 ' & 96-0884) and USACE (Action ID 199503160 and 199600078) for impacts to 3.889 acres of waters within the Governors Village development. The impacts proposed within this application include both modifications to these previous approvals and new impacts not yet approved.

Also, attached are sketch maps of the delineation that were attached to the determination. ' USACE Memo re: Project Area (see attached) - On October 16, 1995 Ms. Jean Manuele wrote a "Memorandum for the Record" stating that the Polk and Dossett Tracts ' (now Governors Village) will be considered separate developments from the Governors Club subdivision as it pertains to the applicability of Nationwide Permit No. 26. We have since received verbal confirmation from the USACE that the Governors Village ' development will be considered a separate development from the Governors Club subdivision. USACE General Permit Verification (see attached) - On April 26, 1996, the USACE issued a General Permit Verification for the use of Nationwide Permits 12, 14 & 26 for impacts to 0.51 acres of waters at the area now know as Governors Village (Action ID 199503160 & 199600078). DWQ Approval #1 (see attached) - On June 8, 1996, the DWQ issued approval for the use of General Water Quality Certifications for impacts to 0.51 acres of waters (DWQ Project No. 96-0362). Impacts maps provided in the original application dated April 10, 1996 are attached. DWQ Approval #2 (see attached) - On October 18, 1996, the DWQ issued approval for the use of General Water Quality Certifications for impacts to 3.889 acres of waters (DWQ Project No. 96-0884). Impacts maps provided in the second application dated September 5, 1996 are attached. In a conversation with Todd Tugwelll of the USACE on February 9, 2005, we understand that the USACE have documentation that the impacts proposed within the second application dated September 5, 1996 have been approved but there is no copy of the approval letter in their files. This application was submitted by S&EC. We have searched our old files, but we have not been able to locate a copy of this letter. ' GOVERNORS VILLAGE PRIOR PROJECT HISTORY USACE Letter of Unauthorized Activity / Permit Noncompliance (see attached) - ' The USACE issued a letter of Notification of Unauthorized Activity / Permit Noncompliance (Action ID 200520149) on December 27, 2004 for this development. In this letter the USACE notified the owner that the construction of the road across a stream ' was not authorized; that a permit had previously been authorized for impacts in the same area (AID 199503160); that the permit had expired prior to the construction of the road; and that the plans have been modified from the originally proposed plans. The remedial action requested within this letter was for the owner to submit an "after-the-fact" ' individual permit application for the stream impacts caused by the road and for any additional fills within waters of the US for completion of the proposed project ' (Governors Village). ' County of Chatham Letter re: Stormwater Pond (see attached) - The Chatham County Planning Director describes in this letter dated April 29, 2005 that the "Village Pond" was previously approved by the County to meet the County Water Supply Watershed stormwater requirements for Governors Village. i i i 1 I U .S.

On October 16,A995, J contacted Mr. Joe Brinn, Jr. with Governors Club Limited Partnership to inform him of our decision regarding the applicability of ' Nationwide Permit No, 26 to the proposed development of Polk Tracts I, IJ and III and the Dossett Tract, owned by the aforementioned partnership. Mr. Brinn was informed that the developers would be allowed to apply for a ' separate Nationwide Permit No. 26 for the Polk and Dossett Tracts since they, are located outside of the main Governors Club subdivision development and will not be entitled to any of the amenities offered within the main ' development. Accordingly, the acreage already issued by nationwide permit in the main subdivision, 2,4 acres, would not be cumulatively affected by wetland permits for the Polk and Dossett tracts. Mr oBrinn stated that he had no problem with this interpretation. Jean B. Manuel Regulatory Specialist ' Raleigh Field.,Office t ` T i 3 qbg ?IOC'?

As such, the applicant proposes to make a payment into the Wetlands Restoration Fund administered by the North Carolina Ecosystem Enhancement Program (NCEEP). The applicant has not yet formally requested the acceptance for this payment from NCEEP. This request will be submitted as soon as the agencies have verified that the impacts listed within this application are correct, have provided guidance on the feasibility of these impacts being approved, have agreed upon the appropriate mitigation ratios, the applicant is both willing and able to make such payment, and NCEEP accepts the requested payment. If in the case that the applicant is neither willing nor able to make this payment once determined by the agencies or NCEEP is not willing to accept the payment, then the applicant will propose an alternative mitigation plan. At this time the applicant proposes to mitigate through payment into the Wetlands Restoration Fund for all permanent wetland impacts (0.365 acres). At this time the applicant is proposing a 1:1 mitigation ratio for these impacts. No mitigation for impacts to open waters and other waters is proposed. The previously approved delineation did not indicate a stream within the location of the road crossing depicted on Impact Map #2 and no stream mitigation was required at that time. We understand that 15` order, headwater streams were not always depicted on delineation maps in 1996 because the agencies did not account for impacts in stream length. However, given that the impacts have already occurred and that we have no documentation of a stream existing within this drainage prior to the impacts occurring it is not clear if a stream ever existed within this location let along the type or quality of stream if one did exist. Also, the DWQ does not require stream mitigation for permanent stream impacts less than 150 feet. Other than the avoidance of additional permanent impacts to streams (including those within areas previously approved for impacts), the applicant does not propose any additional mitigation for the 148 feet of permanent, perennial stream impacts. If this is not acceptable to the USACE, then the applicant proposes payment into the Wetlands Restoration Fund (as described above) for any required stream mitigation. Based on the quality (see Stream Forms) of the stream reach upstream from the crossing the applicant does not believe that a mitigation ratio greater than 1:1 should be required if the USACE requires mitigation. Amount of stream mitigation requested (linear feet): 148 (if required) Amount of buffer mitigation requested (square feet): 0 Amount of Riparian wetland mitigation requested (acres): 0.365 Amount of Non-riparian wetland mitigation requested (acres): 0 GOVERNORS VILLAGE PUBLIC INTEREST ISSUES In a document provided by the U.S. Corps of Engineers titled "Wetlands & Corps Wetland Regulations" and dated August 13, 2001, the Corps of Engineers lists 21 specific factors that will be reviewed related to Public Interest. These factors are similar to the "Evaluation Factors" listed on Page 8 of the U.S. Army Corps of Engineers, Regulatory Program, Application Information document dated May 1985. These items are as follows: Conservation Safety Economics Water Quality Aesthetics Fish & Wildlife Values Wetlands Historic Properties Shore Erosion and Accretion Flood Hazard Water Supply Food & Fiber Production Floodplain Value Navigation Environmental Concerns Land Use Energy Needs Property Ownership Recreation Mineral Needs Needs and Welfare of the People Responses to each of the 21 Public Interest Issues are presented below. Conservation: No additional impacts are proposed to the remaining wetlands, streams and riparian buffers on the site beyond those that have already occurred or those proposed within this ' new application. Water Quality: What is commonly referred is as "Village Pond" located in Governors Village is actually a large stormwater management pond required by Chatham County to meet the County Water Supply Watershed stormwater requirements to control stormwater runoff from Governors Village (see the April 29, 2005 letter from Keith Megginson, Chatham County Planning Director attached to the Prior Project History section of this application). As such, the applicant believes that this pond will be sufficient to meet the DWQ Water Quality Certification requirements (15A NCAC 02H .0506(b)(5)) for the protection of downstream water quality standards through the use of onsite stormwater control measures. ' The construction will meet all of the local, State and Federal design requirements with regards to protection of water quality. The surface waters on site are classified by the ' DWQ as "WS-IV, NSW". The development will comply with all DWQ water quality standards for class "WS-IV, NSW" waters. ' Wetlands: No additional impacts are proposed to the remaining wetlands on the site beyond those that have already occurred or those proposed within this new application. Wetland functions will therefore be retained within these areas. GOVERNORS VILLAGE PUBLIC INTEREST ISSUES The applicant proposes to avoid additional impacts to wetland areas that were previously approved for impacts in 1996 as described within this application and the Wetland Impact Maps. Also, additional wetlands and waters beyond those previously determined to be jurisdictional in 1996 exist on the site today. These areas will be avoided as depicted on the Wetland Impact Maps. Flood Hazard: The project site is located outside of the 100-year floodplain and only has approximately an 80-acre watershed above the stormwater pond therefore flooding is not of concern. The culverts below the proposed road / driveway crossings have been reviewed and approved by the local municipality to ensure the proper passage of any high water events. Floodplain Value: The site is located outside the 100-year floodplain, therefore there are no impacts to any existing FEMA designated floodplain areas. No significant flood plains exist along the headwater stream systems located on the project site. Land Use: The proposed development is currently being or has already been developed as a mixed- use commercial and residential community. The surrounding properties are primarily residential with some commercial and vacant woodland. Recreation: No existing public or private recreational facilities will be negatively affected by the development and operation of the facility. Governors Village property owners will be able to enjoy the recreational activities within the community, including but not limited the walking trails around the "Village Pond". Safety: All entrances to the development along state roads have already or will meet the standards of the North Carolina Department of Transportation (NCDOT). In addition to the NCDOT constraints imposed for the sake of safety, there are also constraints on the construction process by state law and the Occupational Safety and Health Administration. Aesthetics: The applicant does not believe that Governors Village will negatively the affect aesthetics ' of the surrounding properties and many people may feel that this well landscaped community including the large "Village Pond" enhances the aesthetics of the area. ' GOVERNORS VILLAGE PUBLIC INTEREST ISSUES ' Historic Properties: The State Historic Preservation Office, North Carolina Listings in the National Register of Historic Places by County document provided on their web site (see ' http://www.hpo.dcr.state.nc.us/nrlist.htm) does not list any historic places within the property boundaries. The State Historic Preservation Office has been contacted and a copy of their February 22, 2005 response letter is attached. In it they state that they are ' aware of no historic resources that would be affected by the project. Water Supply: The site is located within the Jordan Lake water supply watershed. Chatham County has reviewed the development under their water supply ordinances. The development will comply with all local water supply ordinances as required and approved by the DWQ. The development will comply with all surface water standards for "WS-IV NSW ' waters. "Village Pond" was required by the County to control stormwater runoff from the Governors Village as described in the April 29, 2005 letter from Keith Megginson, Chatham County Planning Director attached to the Prior Project History section of this application. The applicant does not believe that development of the site and the resulting water needs will adversely affect any existing off-site water supplies. Navigation: ' The wetlands and waters proposed to receive fill materials are not located in navigable waters.

Address 11010 Raven Ridge Road Raleigh, NC 27614 Telephone Number 919-876-8441 Size and Location of Property (waterbody, Highway name/number, town, etc.): The property is located adjacent to the Governors Village Town home site, east of Mt. Carmel Church Road, north of Old Farrington Road, southeast of Chapel Hill, Chatham County, North Carolina. The site contains wetlands and unnamed tributaries to Cub Creek, in the Cape Fear River Basin. Description of Unauthorized Activity / Permit Noncompliance: Construction of a road across a stream and wetland system, without permit authorization. A permit had previously been authorized for impacts in the same area (AID 199503160), however the permit had expired prior to construction of the road way, and the plans have been modified from the originally proposed plans. Construction of the road has resulted in the loss of an undetermined length of stream channel. Previous impacts associated with the subdivision currently exceed 0.5 acres, which is the limit for nationwide permit authorization. Additional impacts, including the unauthorized road construction will require individual permit authorization. Indicate Which of the Following Apply: X Unauthorized Activity River and Harbor Act, Section 10 (33 USC 403) Noncompliance with Permit X Clean Water Act, Section 301 (33 USC 1311) Unless you tave a Department of the Army Permit for the above-described activity, it is a violation of federal law as specified above. You have agreed to do no further work in waters or wetlands without the required Department of the Army Permit. Any further unauthorized work in waters or wetlands will be considered an intentional violation of federal law. If you do no further work in waters and wetlands, and perform the remedial action requested below, the Corps of Engineers will take no further action in this matter. If you continue to work in waters and wetlands without the required authorization, and/or fail to perform the requested remedial action, the Corps will take further administrative action, and.may request the U.S. Attorney to file suit against you. If you need further information about the Corps of Engineers regulatory program, please contact Todd Tugwell at telephone number (919) 876 - 8441 extension 26 ?. s Action ID: 200520149 County: Chatham Remedial Action Requested: As indicated during the site meeting of December 20, 2004 with Mr. Joe Faulkner of CE Group, Inc. and Mr. Sean Clark with Soil & Environmental Consultants, Inc., submittal of an after-the-fact individual permit application (enclosed) is required. In addition to applying for existing impacts associated with the road crossing, the application should include all additional fills within waters of the U.S. required for completion of the proposed project.

As such, the applicant proposes to make a payment into the Wetlands Restoration Fund administered by the North Carolina Ecosystem Enhancement Program (NCEEP). The applicant has not yet formally requested the acceptance for this payment from NCEEP. This request will be submitted as soon as the agencies have verified that the impacts listed within this application are correct, have provided guidance on the feasibility of these impacts being approved, have agreed upon the appropriate mitigation ratios, the applicant is both willing and able to make such payment, and NCEEP accepts the requested payment. If in the case that the applicant is neither willing nor able to make this payment once determined by the agencies or NCEEP is not willing to accept the payment, then the applicant will propose an alternative mitigation plan. At this time the applicant proposes to mitigate through payment into the Wetlands Restoration Fund for all permanent wetland impacts (4.365 acres). At this time the applicant is proposing a 1:1 mitigation ratio for these impacts. No mitigation for impacts to open waters and other waters is proposed. The previously approved delineation did not indicate a stream within the location of the road crossing depicted on Impact Map #2 and no stream mitigation was required at that time. We understand that 1" order, headwater streams were not always depicted on delineation maps in 1996 because the agencies did not account for impacts in stream length. However, given that the impacts have already occurred and that we have no documentation of a stream existing within this drainage prior to the impacts occurring it is not clear if a stream ever existed within this location let along the type or quality of stream if one did exist. Also, the DWQ does not require stream mitigation for permanent stream impacts less than 150 feet. Other than the avoidance of additional permanent impacts to streams (including those within areas previously approved for impacts), the applicant does not propose any additional mitigation for the 148 feet of permanent, perennial stream impacts. If this is not acceptable to the USAGE, then the applicant proposes payment into the Wetlands Restoration Fund (as described above) for any required stream mitigation. Based on the quality (see Stream Forms) of the stream reach upstream from the crossing the applicant does not believe that a mitigation ratio greater than 1:1 should be required if the USACE requires mitigation. Amount of stream mitigation requested (linear feet): 148 (if required) Amount of buffer mitigation requested (square feet): 0 Amount of Riparian wetland mitigation requested (acres): 0.365 Amount of Non-riparian wetland mitigation requested (acres): 0 GOVERNORS VILLAGE PUBLIC INTEREST ISSUES In a document provided by the U.S. Corps of Engineers titled "Wetlands & Corps Wetland Regulations" and dated August 13, 2001, the Corps of Engineers lists 21 specific factors that will be reviewed related to Public Interest. These factors are similar to the "Evaluation Factors" listed on Page 8 of the U.S. Army Corps of Engineers, Regulatory Program, Application Information document dated May 1985. These items are as follows: Conservation Safety Economics Water Quality Aesthetics Fish & Wildlife Values Wetlands Historic Properties Shore Erosion and Accretion Flood Hazard Water Supply Food & Fiber Production Floodplain Value Navigation Environmental Concerns Land Use Energy Needs Property Ownership Recreation Mineral Needs Needs and Welfare of the People Responses to each of the 21 Public Interest Issues are presented below Conservation: No additional impacts are proposed to the remaining wetlands, streams and riparian buffers on the site beyond those that have already occurred or those proposed within this new application. Water Quality: What is commonly referred is as "Village Pond" located in Governors Village is actually a large stormwater management pond required by Chatham County to meet the County Water Supply Watershed stormwater requirements to control stormwater runoff from Governors Village (see the April 29, 2005 letter from Keith Megginson, Chatham County Plaiming Director attached to the Prior Project History section of this application). As such, the applicant believes that this pond will be sufficient to meet the DWQ Water Quality Certification requirements (15A NCAC 02H.0506(b)(5)) for the protection of downstream water quality standards through the use of onsite stormwater control measures. The construction will meet all of the local, State and Federal design requirements with regards to protection of water quality. The surface waters on site are classified by the DWQ as "WS-IV, NSW". The development will comply with all DWQ water quality standards for class "WS-IV, NSW" waters. Wetlands: No additional impacts are proposed to the remaining wetlands on the site beyond those that have already occurred or those proposed within this new application. Wetland functions will therefore be retained within these areas. GOVERNORS VILLAGE PUBLIC INTEREST ISSUES The applicant proposes to avoid additional impacts to wetland areas that were previously approved for impacts in 1996 as described within this application and the Wetland Impact Maps. Also, additional wetlands and waters beyond those previously determined to be jurisdictional in 1996 exist on the site today. These areas will be avoided as depicted on the Wetland Impact Maps. Flood Hazard: The project site is located outside of the 104-year floodplain and only has approximately an 80-acre watershed above the stormwater pond therefore flooding is not of concern. The culverts below the proposed road / driveway crossings have been reviewed and approved by the local municipality to ensure the proper passage of any high water events. Floodplain Value: The site is located outside the 100-year floodplain, therefore there are no impacts to any existing FEMA designated floodplain areas. No significant flood plains exist along the headwater stream systems located on the project site. Land Use: The proposed development is currently being or has already been developed as a mixed- use commercial and residential community. The surrounding properties are primarily residential with some commercial and vacant woodland. Recreation: No existing public or private recreational facilities will be negatively affected by the development and operation of the facility. Governors Village property owners will be able to enjoy the recreational activities within the community, including but not limited the walking trails around the "Village Pond". Safety: All entrances to the development along state roads have already or will meet the standards of the North Carolina Department of Transportation (NCDOT). In addition to the NCDOT constraints imposed for the sake of safety, there are also constraints on the construction process by state law and the Occupational Safety and Health Administration. Aesthetics: The applicant does not believe that Governors Village will negatively the affect aesthetics of the surrounding properties and many people may feel that this well landscaped community including the large "Village Pond" enhances the aesthetics of the area. GOVERNORS VILLAGE PUBLIC INTEREST ISSUES Historic Properties: The State Historic Preservation Office, North Carolina Listings in the National Register of Historic Places by County document provided on their web site (see http:/; NvNvNv.hpo.dcr.state.nc.usirirlist.htm) does not list any historic places within the property boundaries. The State Historic Preservation Office has been contacted and a copy of their February 22, 2005 response letter is attached. In it they state that they are aware of no historic resources that would be affected by the project. Water Supply: The site is located within the Jordan Lake water supply watershed. Chatham County has reviewed the development under their water supply ordinances. The development will comply with all local water supply ordinances as required and approved by the DWQ. The development will comply with all surface water standards for "WS-IV NSW" waters. "Village Pond" was required by the County to control stormwater runoff from the Governors Village as described in the April 29, 2005 letter from Keith Nlegginson, Chatham County Planning Director attached to the Prior Project History section of this application. The applicant does not believe that development of the site and the resulting water needs will adversely affect any existing off-site water supplies. Navigation: The wetlands and waters proposed to receive fill materials are not located in navigable waters. No impacts to navigation are anticipated as a result of site development. Energy Needs: Electrical energy for the development will be supplied by the local network as operated by Progress Energy. The development will not generate any of its own power and will not have energy needs in excess of normal residential development. Mineral Needs: Neither supply nor demand for mineral resources will be negatively affected by the development of this site. Economics: The applicant does not believe that the development will have a negative affect on the economy of the surrounding community. In fact, the new residences and businesses will provide new property taxes and spark retail and service related businesses within the nearby communities. GOVERNORS VILLAGE PUBLIC INTEREST ISSUES Fish & Wildlife Values: The following species have been federally listed as Threatened or Endangered for Chatham County: Bald Eagle Haheetus leucocephalus Threatened Red-cockaded woodpecker Picoides borealis Endangered Cape Fear Shiner Notropis mekistocholas Endangered Harperella Phlimnium nodosum Endangered Of these, the Bald Eagle is the only federally listed Threatened or Endangered species listed on the Farrington, NC USGS topographic quadrangle. Utilizing the N.C. Natural Heritage Program (NHP) database of all recorded protected species occurrences, S&EC found that there are no federally listed species occurring onsite. However, within a three-mile radius of the site, five occurrences of the Bald Eagle (Haliaeetus leucocephalus), as recently as 2003 have been recorded. These occurrences are shown on the attached map. It is not expected that activities at the subject property will have a detrimental effect on the Bald Eagle population. No direct or secondary adverse impacts to federally listed species are expected from the construction of the proposed subdivision. Village Pond located on the property and retained stream, wetland and riparian corridors are anticipated to provide habitat and wildlife corridors both within and through the community. Shore Erosion & accretion: This public interest issue is not applicable to this application as the development will not affect shore erosion or accretion. Food & Fiber Production: The development will produce neither food nor fiber as part of the facility operations. Environmental Concerns: 1'V oise No adverse impacts to noise levels in the area are anticipated from the development of this site. GOVERNORS VILLAGE PUBLIC INTEREST ISSUES Prevention ofContainination All construction activities and resulting infrastructure will be in compliance with applicable environmental laws. No facilities are planned that have a significant risk for production or release of environmental contaminants. Erosion and,' "ediTnentation Construction at the site will be performed under an approved Erosion and Sedimentation Control Plan to minimize sedimentation and erosion in the construction areas. StoiYn«vater during construction will be managed using sedimentation basins and other control devises that will reduce the sediment load in runoff and will attenuate peak flow rates to prevent downstream erosion. Air Quality No adverse impacts to local air quality are anticipated as a result of this development. Property Ownership: The applicant currently owns the portions of the development where impacts to waters are proposed. Many of the properties within the remainder of the development have been sold and currently have multiple different property owners. Adjacent property owners to Governors Village are listed in Block 24. Needs and Welfare of the People: The applicant believes that the completion of this development will go towards meeting the increasing needs of housing and services for the future residents of this community and Chatham County and will in turn enhance the welfare of the people of this community and it's future residents. ? % & FEB 2 4 2005 JU North Carolina Department of Cultural Resources State Historic Preservation Office Peter B.

GOVERNORS VILLAGE BLOCK SHEETS BLOCK 18 - Nature of Activity The project involves the completion of development of Governors Village mixed-use commercial and residential subdivision located in northern Chatham County, NC. As described further in Block 23, much of the development has already been completed. Construction of Governors Village began in the mid-1990s. Approvals have been received by both the U.S. Army Corps of Engineers (USAGE; Action ID 199503160 and 199600078) and the N.C. Division of Water Quality (DWQ; Project No. 96-0392 and 96- 0884). No additional impacts to waters beyond those previously approved or requested within this application are anticipated at this time. The applicant is requesting approval to impact waters for an existing road crossing (see Impact Map #2 and the USACE Notification of Unauthorized Activity provided in the attached Prior Project History section of this application). In addition to this road crossing the applicant is requesting approval to impact wetlands and waters for the construction of one additional road crossing (see Impact Map #3), utility crossings and lot fill. Many of these impacts were previously approved, but they have not yet occurred and the previous approvals have expired. These activities and the dimensions of the structures are illustrated in the attached "Impact Maps". The materials to be used include earthen fill to construct the base for the roads and lots. The roads and parking areas will be paved and use curb and gutter to manage stormwater runoff. Paving materials include asphalt and concrete. Curb and gutter materials include concrete metal drop inlets and reinforced concrete pipes (RCP). The existing road crossing (see Impact Map #2) was constructed using twin 42" RCPs (see Site Photo). The proposed second crossing (see Impact Map43) will be installed using a single 54" RCP. The residential structures both already built and proposed include stick-built single-family homes and townhomes with concrete driveways and walks. The commercial buildings are constructed of typical commercial building materials including primarily steel, concrete block, brick and glass. The previously approved and constructed pond commonly referred to as the "Village Pond" is a large, stormwater management pond required by the County to meet the Chatham County Water Supply watershed stormwater requirements for Governors Village (see attached letter from Chatham County dated April 29, 2005 provided within the attached Prior Project History section of this application). Stormwater runoff from Governors Village (including the proposed development areas not currently constructed) drain to and are managed by this pond. GOVERNORS VILLAGE BLOCK SHEETS BLOCK 19 - Project Purpose Project Purpose: The purpose of this project is to complete construction of development of Governors Village, a mixed-use commercial and residential development located between Mt. Carmel Church Road, Whipporwill Lane and Old Farrington Road in northern Chatham County, NC. There are basically three properties that have not been developed within Governors Village. The properties north and west of the "Village Pond" were previously approved by the USACE and DWQ for impacts to wetlands and waters. The property east of the "Village Pond" was added to Governors Village this spring. No jurisdictional wetlands or waters are proposed to be impacted on this property other than the road crossing impacts (see Impact Map #3) to connect this property to the rest of Governors Village. Properties to the south of the "Village Pond" are not part of Governors Village and consist of existing residential properties. Project Need: Governors Village provides retail, office, other commercial services and housing for residents within the surrounding community as well as existing and future residents within Governors Village. This development helps to address service and housing needs of the community's growing population. GOVERNORS VILLAGE BLOCK SHEETS BLOCK 20 - Reasons for Discharge Proposed Commercial / Retail Area - The wetland impact proposed on Impact Map #1 is required to complete construction of the commercial / retail section of Governors Village previously planned for the development in the mid-1990s. These impacts were previously approved by both the USACE and DWQ (see the Prior Project History section attached to this application). Existing Road Crossing - The existing road crossing (see Impact Map #2) was required to provide a second access for the existing townhomes north of the "Village Pond". The crossing not along improves traffic flow through Governors Village, it also provides for multiple points of ingress and egress in case of any emergency. Proposed Second Crossing - The proposed second crossing (see Impact Map #3) is required to connect the new 49-lot single-family residential subdivision east of "Village Pond" to the remainder of Governors Village. Without this crossing the residents of this community would need to utilize existing state roads (Old Farrington Road, etc.) and at least one intersection of state roads just to drive from their home to the retail area of Governors Village. This is not only twice the distance it will also lead to unnecessary traffic congestion on these state roads. In addition to connecting the subdivision to the remainder of Governors Village, this crossing will provide a second point of ingress and egress for the community. Proposed Townhomes - The wetland impact proposed on Impact Map #4 is to fill wetlands within a drained pond bottom to allow for the construction of residential townhomes west of the "Village Pond". This property (previously known as the Dossett Parcel) has recently been approved by Chatham County for the construction of 76 townhomes from the previously approved commercial / office development. The wetland area has a surface connection to the "Village Pond" via a channel that is not depicted on either the USGS topographic map or Chatham County Soil Survey. The channel was determined by S&EC staff to be an ephemeral ditch below the wetland / drained pond and above the existing walking trail around the "Village Pond". The applicant does not dispute the jurisdiction of this wetland area or it's determination as non-isolated. However it should be noted that S&EC staff do not believe that this original pond in this location was constructed on either an intermittent or perennial stream. The quality and functions of this wetland area are low compared to other wetland systems. Utilities - Impacts to wetlands and waters for utility crossings are also proposed on Impact Maps #2 and #3. These impacts are required to provide utility services to development areas described within this application.

Existing Conditions: The project involves the completion of the development of the Governors Village residential and commercial mixed-use development located on Mt. Carmel Church Road (SR 1008) in Chatham County, NC. A large portion of the development has already been constructed, residential and commercial lots have been sold, buildings and homes have been constructed, and businesses and residents are occupying their buildings and homes. The road ! driveway crossing depicted on Impact Map #2 has already been constructed. The owner believed that all appropriate 404 and 401 approvals had been received at the time the road was constructed. However, the owner was notified in a letter dated December 27, 2004 from Mr. Todd Tugwell of the U. S. Army Corps of Engineers (US ACE) that this activity was not authorized (Action ID 200520149). The USACE and DWQ previously authorized impacts to these waters as described in the attached Prior Project History. Although as Mr. Tugwell explains in his letter, the permit had expired prior to construction of the roadway, and the plans have been modified from the originally proposed plans. The additional impacts proposed within this application have not yet been constructed. Dredged or Fill Material Already Discharged: The activities within Waters of the U. S. that have already occurred include the discharge of fill into wetlands and other waters for the development of roads, utilities, and commercial and residential lots. Waters have also been impacted by both fill and flooding for the construction of the stormwater management pond. Previous Agency Involvement & Approvals: Please refer to the attached Prior Project History for additional information and reference materials. Approvals have been received from the DWQ (DWQ Project No.(s) 96-0362 & 96-0884) and USACE (Action ID 199503160 and 199600078) for impacts to 3.889 acres of waters within the Governors Village development. The impacts proposed within this application include both modifications to these previous approvals and new impacts not yet approved.

Assign points to each characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics identified in the worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot be evaluated due to site or weather conditions, enter 0 in the scoring box and provide an explanation in the comment section. Where there are obvious changes in the character of a stream under review (e.g., the stream flows from a pasture into a forest), the stream may be divided into smaller reaches that display more continuity, and a separate form used to evaluate each reach. The total score assigned to a stream reach must range between 0 and 100, with a score of 100 representing a stream of the highest quality. Total Score (from reverse): LAS Evaluator's Signature ??' Date 1x1/i/ This channel evaluation is intended to be used only as a guide to assist landowners a ironmental professionals in gathering the data required by the United States Army Corps of Engineers in order to make a preliminary assessment of stream quality. The total score resulting from the completion of this form is subject to USACE approval and does not imply a particular mitigation ratio or requirement. Form subject to change - version 05/03.

Assign points to each characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics identified in the worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot be evaluated due to site or weather conditions, enter 0 in the scoring box and provide an explanation in the comment section. Where there are obvious changes in the character of a stream under review (e.g., the stream flows from a pasture into a forest), the stream may be divided into smaller reaches that display more continuity, and a separate form used to evaluate each reach. The total score assigned to a stream reach must range between 0 and 100, with a score of 100 representing a stream of the highest quality. Total Score (from reverse): .3(a Comments: Evaluator's Signature it J a Date -Z r oj- This channel evaluation fo intended to be used only as a guide to assist landowners and environmental professionals in gathering the data required by the United States Army Corps of Engineers in order to make a preliminary assessment of stream quality.

Also, attached are sketch maps of the delineation that were attached to the determination. USACE Memo re: Project Area (see attached) - On October 16, 1995 Ms. Jean Manuele wrote a "Memorandum for the Record" stating that the Polk and Dossett Tracts (now Governors Village) will be considered separate developments from the Governors Chub subdivision as it pertains to the applicability of Nationwide Permit No. 26. We have since received verbal confirmation from the USACE that the Governors Village development will be considered a separate development from the Governors Club subdivision. USACE General Permit Verification (see attached) - On April 26, 1996, the USACE issued a General Permit Verification for the use of Nationwide Permits 12, 14 & 26 for impacts to 0.51 acres of waters at the area now know as Governors Village (Action ID 199503160 & 199600078). DWQ Approval #1 (see attached) - On June 8, 1996, the DWQ issued approval for the use of General Water Quality Certifications for impacts to 0.51 acres of waters (DWQ Project No. 96-0362). Impacts maps provided in the original application dated April 10, 1996 are attached. DWQ Approval 92 (see attached) - On October 18, 1996, the DWQ issued approval for the use of General Water Quality Certifications for impacts to 3.889 acres of waters (DWQ Project No. 96-0884). Impacts maps provided in the second application dated September 5, 1996 are attached. In a conversation with Todd Tugwelll of the USACE on February 9, 2005, we understand that the USACE have documentation that the impacts proposed within the second application dated September 5, 1996 have been approved but there is no copy of the approval letter in their files. This application was submitted by S&EC. We have searched our old files, but we have not been able to locate a copy of this letter. GOVERNORS VILLAGE PRIOR PROJECT HISTORY USACE Letter of Unauthorized Activity I Permit Noncompliance (see attached) - The USACE issued a letter of Notification of Unauthorized Activity / Permit Noncompliance (Action ID 200520149) on December 27, 2004 for this development. In this letter the USACE notified the owner that the construction of the road across a stream was not authorized; that a permit had previously been authorized for impacts in the same area (AID 199503160); that the permit had expired prior to the construction of the road; and that the plans have been modified from the originally proposed plans. The remedial action requested within this letter was for the owner to submit an "after-the-fact" individual permit application for the stream impacts caused by the road and for any additional fills within waters of the US for completion of the proposed project (Governors Village). County of Chatham Letter re: Stoinnwater Pond (see attached) - The Chatham County Planning Director describes in this letter dated April 29, 2005 that the "Village Pond" was previously approved by the County to meet the County Water Supply Watershed stormwater requirements for Governors Village.

The surveyed wetland lines must be verified by our staff before the Corps will make a final jurisdictional determination on your property. • Because of the size of your property and our present workload, our identification and delineation of your wetlands cannot be accomplished in a timely manner. You may wish to employ a consultant to obtain a more timely delineation of the wetlands. Once your consultant has flagged a wetland line on the property, Corps staff will review it, and, if it is accurate, we strongly recommend that you have the line surveyed for final approval by the Corps. The Corps will not make a final jurisdictional determination on your property without an approved survey. • The wetlands on your lot have been delineated, and the limits of Corps jurisdiction have been explained to you. Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed years from the date of this notification. • There are no wetlands present onthe above described property which are subject to the permit requirements of Section 404 of the Clean Water Act (33 USC 1344). Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed three years frorp the date of this notification. • The project is located in one of the 20 Coastal Counties. You should contact the nearest State Office of Coastal Management to determine their requirements. Placement of dredged or fill material in wetlands on this property without a Department of the Army permit is in most cases a violation of Section 301 of the Clean Water Act (33 USC 1311).

Memorandum To: MEMORANDUM FOR THE RECORD CC: From: Jean B. Manuele Date: 'October 16, 1995 Subject: - Action ID. 199503160 and`. 199600078, Nationwide Permit No. 26 Applicability to Subdivision for Governors Club Limited Partnership, Polk and Dossett Tracts, South of Chapel Hill, Chatham County, North Carolina. On October 16, 1995, I contacted Mr. Joe Brinn, Jr. with Governors Club Limited Partnership to inform him of our decision regarding the applicability of Nationwide Permit No. 26 to the proposed development of Polk Tracts I, II and III and the Dossett Tract, owned by the aforementioned partnership. Mr. Brinn was informed that the developers would be allowed to apply for a separate Nationwide Permit No. 26 for the Polk and Dossett Tracts since they are located outside of the main Governors Club subdivision development and will not be entitled to any of the amenities offered within the main development. Accordingly, the acreage already issued by nationwide permit in the main subdivision, 2.4 acres, would not be cumulatively affected by wetland permits for the Polk and Dossett tracts. Mr 4Brinn stated that he had no problem with this interpretation. Jean B.
