After reviewing your application, we have decided that this fill is covered by General Water Quality Certification Numbers 3127, 3103 and 3108. These certifications allow you to use Nationwide Permit Numbers 3, 14 and 26 when the Corps of Engineers issues them. In addition, you should get any other federal, state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and Water Supply Watershed regulations. This approval will expire when the accompanying 404 or CAMA permit expires unless otherwise specified in the General Certification. This approval is only valid for the purpose and design that you described in your application except as modified below. If you change your project, you must notify us and you may be required to send us a new application for a new certification. If the property is sold, the new owner must be given a copy of this Certification and approval letter and is thereby responsible for complying with all conditions. If total wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h). For this approval to be valid, you must follow the conditions listed in the attached certification and any additional conditions listed below. 1. Deed notifications or similar mechanisms shall be placed on all remaining jurisdictional wetlands and waters to notify the state in order to assure compliance for future wetland and/or water impact.

Mecklen burg County. North Carolina - Nationwide Permit 426. #14. #3 Dear Sirs: On behalf of my clients, Mr. J. Bart Bopper of Odell School Highway Investment Traders, LLC., I am providing you with the following information concerning Mill Creek for your consideration. The project site is located on former agricultural land near proposed I-485. The project is planned to be a mixed use development consisting of multi-family, single family, and commercial areas. The project concept has been locally approved through re-zoning procedures. In order to balance the site's economic viability with its environmental value and permitability, the developer has planned the project to minimize impacts to important streams and wetlands. Proposed impacts are those required to make required road crossings and. to meet local detention requirements. The developer proposes to utilize the North Carolina Wetland Restoration Program meet mitigation requirements for unavoidable impacts to streams and wetlands. A Stormwater Management Plan will also be implemented for portions of the project that consist of Commercial, Office, Corporate, and Business land uses. Stormwater management facilities will include stormwater wet ponds, and/or other approved treatment facility. An existing pond is proposed to be converted for use as a stormwater management facility. SUMMARY OF WATERS OF THE U. S. Methodology Preliminary identification and delineation of the Jurisdictional Waters on the site were determined according to the Corps of Engineers Wetland Delineation Manual, Technical Report Y-87-1, 1987, with Appendices. Preliminary data gathering included review and interpretation of topographic maps; USDA Soil Conservation Survey; aerial photographs, and preliminary site visits to selected areas. Then the Routine On-Site Determination Method was utilized to determine the upper boundary of the wetlands. In order to make-.a positive wetland determination indicators of hydrophytic vegetation, hydric soil, and wetland hydrology must be identified. as described in the manual. Mr. Steve Chapin - USACE, Mr. John R. Dorney, Mr. Mike Parker - NCDWQ Page 2, January 26, 2000 General Wetland Classification and Description The wetlands and riparian areas on this site can be describe as Palustrine Forested Broad, Scrub/Shrub, and Emergent Temporarily Flooded and Seasonally Flooded. Vegetation A majority of the site is former agricultural and woodland in various stages of succession. Except for the immediate fringe along the pond edges, the wetland areas are generally forested. Bottomland Hardwood/Headwater Forest The Bottomland Hardwood and Headwater Forests on this site have developed in the flat to nearly level drainageways and depressions. Species which occur in these areas include willow oak„ green ash, sweetgum, red maple, and other typical species that tolerate these wet and shallow root conditions, Common understory trees and shrubs include boxelder, silky dogwood, privet, and alder. Woody vines include poison ivy, honeysuckle, and greenbriar. The herbaceous layer is variable based on exposure to light. Species include sedge and rush species, jewelweed, microstegium, and others Mixed Forest The non-wetland forested areas of the site are dominated by mixed forest. The Mixed Forest is characterized by a mixture of canopy species of pines and hardwoods. Small areas within these forest areas may have a predominance of pine or hardwoods. Pines include shortleaf pine, Virginia pine, and loblolly pine, with eastern redcedar. Hardwoods include sweetgum, red maple, beech, red oak, white oak, tulip poplar, hickory, and other common species. The subcanopy contains saplings and seedlings of canopy species. Other subcanopy species include black cherry, American holly, dogwood, elm, and dense areas of privet and russian olive. Woody vines common in the understory include poison ivy, muscadine grape, honeysuckle, and other herbaceous and woody species. Hydrophytic Vegetation has been identified according to the National List of Plant Species That Occur in Wetlands: Southeast (Region .l US Department of the Interior, Fish and Wildlife Service. Hydric Soils Hvdric Soils The site includes Monacan and. Helena soils. These soils are map units which may have inclusions of hydric soils according to the Natural Resource Conservation Service), Technical Guide-Section II-A-2, June 1991. Hydrology Water Classification - The drainage features are unnamed tributaries of the Rocky River in the Yadkin River Basin. These are currently classified a Class C - aquatic He propagation and survival, fishing, wildlife, secondary recreation, and agriculture. Wetland hydrology is provided by a surface runoff; overbank flooding, seeps, and. springs over a clayey subsoil. Wetlands associated with the tributaries are the result surface runoff, springs, high seasonal water table, and man-made impoundments. The clayey subsoils contribute to the development of perched wetlands along the tributaries. Most of the primary streams on the site (perennial and intermittent) will likely be confirmed as Mr. Steve Chapin - USACE, Mr. John R. Dorney, Mr. Mike Parker - NCDWQ Page 3, January 26, 2000 having important aquatic value by the USACE and/or the NCDWQ. Characteristics include persistent pools, riffle and pool complexes, fish, amphibians and macro-invertebrates; evidence of wildlife utilizing the stream; and rocky, gravelly, and sandy channel substrate. SUMMARY OFT 14 )1 'TI IN I WA OF THE 7 4 Surface Waters Streams with important aquatic function +1.25 acres (± 4,700 If) Streams with unimportant aquatic function ±0.05 acres (± 2801f) Wetlands PFOIA PSS1A ±0.22 acres Pond P Hh +1.30 acres Approximate Total - Waters of the U.S. ±2.82 acres Approximately 88% of the jurisdictional streams will not be impacted by the proposed development. Impacts to important streams are the minimized to necessary stream crossings and for required storm water detention facilities. Large linear sections of stream will be preserved and remain undisturbed. Unavoidable impacts to streams to make road, crossings will be mitigated at a minimum 1:1 ratio utilizing the North Carolina Wetland Restoration Program as required. Riparian stream buffers have been provided to the extent feasible, as depicted on the plans. A Stormwater Management Plan will also be implemented for portions of the project that consist of Commercial, Office, Corporate, and Business land uses. Stormwater management facilities will include stormwater ponds, and/or extended stormwater wetlands, if required. PROPOSED IMPACTS Surface Waters Streams with important aquatic function w/NWP #26 ±0.06 acres (+48210 Streams with unimportant aquatic function w/NWP#26 ±0.02 acres (±28010 Streams with important aquatic function w/NWP #14 ±0.02 acres (± 1471f) Wetlands PFOIA PSS1A ±0.20 acres Approximate Total - Waters of the U.S. ±0.30 acres One temporary construction crossing (at a proposed crossing location) will he constructed to.facilitate clearing, and soil testing. Impact will he less than 150 linear feet. Nationwide Permit 3 will he utilized to repair and upgrade the existing dam to convert the pond into a stormwater treatment facility. Mr. Steve Chapin - USACE, Mr. John R. Dorney, Mr. Mike Parker - NCDWQ Page 4, January 26, 2000 The project has been designed through an alternative analysis to avoid and minimize impacts to Waters of the United States to the extent practicable. Approximately 88% of the important jurisdictional streams on this site have been avoided PROPOSED MINIMIZA TION AND MITIGATION A mitigation plan is proposed for a "no net loss" of wetland, stream, and pond habitat, value, and function to the extent feasible on this site. Avoidance- Minimization, and itiea ion Due to the economic, engineering, and spatial requirements of a development of this magnitude, large contiguous areas must be graded for building pads and site other requirements. However the following Best Management Practices will be employed to minimize impacts to Jurisdictional Waters. These will include: a) Siltation Barriers; Sediment Traps and Diversion Ditches b) Barricades to define construction limits to sensitive sites and to protect trees c) Methods to prevent short term impacts will be inspected regularly and maintained during construction of the project. d) Project construction will strictly adhere to an approved. Sedimentation and Erosion Control Plan. Best Management Practices will include utilizing siltation trapping ponds and other erosion control structures where appropriate. Impacts from hazardous materials and other toxins to fish and aquatic life such as fuels will be avoided by not permitting staging areas to be located near surface waters. e) As required by the 401 Water Quality Certification conditions, measures will be taken to prevent "live" or fresh concrete from coming into contact with waters until the concrete has hardened. Except for temporary construction and development impacts, we believe that the proposed project with the proposed. mitigation will not cause significant cumulative impacts to the ecological functions or values of Jurisdictional Waters of the United States. mitigation plan is proposed for a. "no net loss" of stream habitat, value, and function to the extent feasible i this site. UnKvoidable imnacts to streams by Qradinty are nronn%ed to he mitigated by huf'Pere re required. Stream impacts by flooding will be mitigated by the protection of the remaining channels the development of a forebay/ and. vegetated littoral zone in connection with the required detention The remaining streams on the project site appear to be in excellent to good condition and will be protected. by buffers to the extent feasible. To meet restoration mitigation requirements for the unavoidable stream impacts, the developer is proposing to contribute $78,625 to the North Carolina Wetland Restoration Program (629 If X $125/ If) to mitigate for stream impacts. Mr. Steve Chapin - USACE, Mr. John R. Dorney, Mr. Mike Parker - NCDWQ Page 5, January 26, 2000 STORMWATER MANAGEMENT PLAN A Stormwater Management Plan will be designed and implemented for the project to meet the 401 Water Quality Certification requirements, if required. The Stormwater Management Plan will include wet detention basins shall be the primary treatment system for stormwater runoff from paved surfaces and landscaping on commercial, office, business, and. institutional parcels. The wet detention basins that will attenuate the first inch of rainfall over a 24 hour period from most of the developed portions of the site. Water will be released over a 2 to 5 day period to the wetland mitigation areas to increase filtration. Discharge velocity of the outclass will be less than five cfs. They will utilize wetland mitigation areas to increase filtration. A littoral zone/forebay will be incorporated into the design of the ponds to encourage additional nutrient removal. The planners will utilize information and guidelines provided by the North Carolina Department of Environment, Health, and Natural Resources in developing the design of wet detention basins using the Table 1.1 in the Stormwater Best Management Practices, NCDENR, November, 1995. AQUATIC HABITAT The aquatic systems in the project area consist of riparian areas associated with tributaries. A variety of wildlife is supported by these systems including mammals, birds, reptiles, amphibians, fish, insects, mollusks, and crustaceans. Therefore strict adherence to an approved erosion and sedimentation control plan will be maintained during the construction period in order to control degradation of water quality downstream and protect the areas to be preserved. Short term construction impacts, primarily stream sedimentation will affect aquatic habitat, however this will be minimized to the extent practicable to promote rapid recovery. Best Management Practices will include utilizing siltation trapping ponds and other erosion control structures where appropriate. Impacts from hazardous materials and other toxins to fish and aquatic life such as fuels will be avoided by not permitting staging areas to be located near surface waters. Also, as required by the 401 Water Quality Certification conditions, measures will be taken to prevent "live" or fresh concrete from coming into contact with waters until the concrete has hardened. Aquatic resources are expected to be enhanced through the development of the stormwater detention ponds and littoral zones. THREATENED AND ENDANGERED SPECIES Federally listed plant and animal species with endangered or threatened status are protected under the Endangered Species Act of 1973. The US Fish and Wildlife Service has identified two endangered species - Sehweinitz's sunflower (Helianthus schweinitzii), and the Carolina heelsplitter (Lasmigona decorata). Schweinitz's sunflower thrives in full sun characteristic of succession fields, margins, and forested openings. Portions of the site are currently in old field succession and secondary succession. The site is forested and characterized by heavy overgrowth in open areas including blackberry, honeysuckle, eleagnus, and ligustrum. Other areas have been recently utilized for agricultural purposes. An evaluation of the site indicated that Schweinitz's sunflower was not present in the -ject area The Carolina heelsplitter is a freshwater mussel which prefers shaded areas either in a ponded portion of a small stream or in runs along steep banks with moderate current. Primary habitat are waters less than three feet deep with a soft mud, muddy sand, or shady gravelly substrate. It is normally restricted to protected silted areas or under banks especially associated with obstructions such as stumps or fallen trees. Its current distribution according to the US Fish and Wildlife Service is limited to portions of two streams -- Goose Creek and Waxhaw Creek -- and a small river originating from rural areas in Union County. Therefore it is does not occur on this site. Mr. Steve Chapin - USACE, Mr. John R. Domey, Mr. Mike Parker - NCDWQ Page 6, January 26, 2000 State Protected Species The Carolina Darter (Etheostoma collis) is a fish that inhabits small streams such as those found in the project vicinity. This species has a federal status of Proposed Special Concern and a state status of Special Concern. The species prefers small clear streams of less than 15' width with moderate to swift current and. a sand/gravel benthic composition. It apparently tolerates a wide range of water quality conditions and vegetation types adjacent to the streams and appears resistant to pollution. (E. Menhinick). Therefore, strict adherence to an approved erosion and sedimentation control plan will be maintained during the construction period in order to control degradation of water quality. PROTECTION FROM FUTURE DEVELOPMENT The preserved. jurisdictional waters will be protected from future impacts by the applicant or by a group designated by the applicant for this purpose. As required, development of these areas will be deed restricted in accordance with restrictive covenants, or similar mechanisms which will be developed for approval by the USACE and/or NCDWQ CULTURAL RESOURCES The State Historic Preservation Office may review of the USGS maps at the Office of State Archaeology and the Survey and Planning Office of the North Carolina Department of Cultural Resources to determine if sites are indicated on the National Historic Register within the study area. CONCLUSION The 97 acre development will provide important economic benefits to the region. Based on the value of the jurisdictional waters and wetlands on this site, the developer through sensitive site planning has chosen to balance the site's economic viability with its environmental value and permitability. The goal of the Site Plan and Mitigation Plan is to help balance the environmental consequences of this development by minimizing impact to riparian habitat, preserving the Jurisdictional Waters of the U.S. remaining on the site, and supporting stream restoration with the NCWRP. The undisturbed areas will be preserved by the applicant or by a group designated by the owner for this purpose. Please contact me if you have any questions or require additional explanation.

Fullwood, Executive Director TO: John Dorney, DWQ 401 Certification Program ?1•? FROM: Ron Linville, Regional Coordinat Habitat Conservation Program DATE: February 21, 2000 SUBJECT: Review of 404/401 Application, Odell School Highway Investment Traders, LLC, unnamed tributary of Rocky River, Mecklenburg County The applicant is requesting a letter of concurrence from the North Carolina Wildlife Resources Commission (NCWRC) to obtain a 404 Permit from the U.S. Army Corps of Engineers and a 401 Certification from the Division of Water Quality. These comments are provided in accordance with provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et. seq.) and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). Impacts from this development will be 909 linear feet of stream and 0.20 acres of wetlands. A payment of $78,625 to the NC Wetlands Restoration Program is proposed. The North Carolina Wildlife Resources Commission (NCWRC) continues to be concerned about the fragmentation and loss of forested areas or woodlands as development occurs in areas near the City of Charlotte and in or near Mecklenburg County. Communities that are designated as bird sanctuaries are causing irreparable harm to avian species by development practices that destroy terrestrial and aquatic habitats. We appreciate the efforts to protect water quality by providing stormwater detention and treatment. However, the NCWRC does not encourage the utilization of existing waters or wetlands for water quality treatment facilities. The NCWRC supports utilizing deed restrictions or restrictive covenants on the remaining jurisdictional areas. Mill Creek Odell Sch Hwy.doc. Page 2 02/21/00 We recommend that, whenever possible, the stream be relocated using bioengineering methods and that a naturally forested buffer of at least 50 feet be provided on each side of the relocated stream channel. Deed restrictions or conservation easements should be utilized to protect habitats and water quality. State or local minimum buffers must be met. The stormwater treatment pond should be built out of the stream. If this stream is located on a water supply watershed and if it is perennial, the buffer requirements for high-density development is 100 feet from the streambank edge. When impounding these waters, the buffer should extend from the edge of the pond. If stream relocation is not economically feasible or practicable, we recommend that the wet detention facility include vegetated littoral shelves for aquatic edge habitat as routinely required in 401 Certifications. Buttonbush, black willow, tag alder, wax myrtle and river birch would be appropriate in this vicinity. Tag alder may not be appropriate in nutrient sensitive watersheds. To restore biodiversity (especially avian and terrestrial habitats) and to enhance aquatic/detritus habitats in the detention facility, we recommend that the applicant provide for the restoration of tree and shrub species similar to those previously found on or near the site. Native species such as wild cherry, hickory and oak may be preferred due to structural concerns and wildlife benefits. These trees and shrubs should be planted around and on the upper third of the detention structure, excluding the dam. When mature, this reforested and edge habitat should restore some habitats and functions lost through development. It should partially restore aquatic habitats, reduce exposure of the water surface to sunlight thereby reducing thermal pollution, provide essential summer and winter forage and habitats, and provide an aesthetically pleasing green space that should improve property values. Walking trails (6' maximum width) associated with this environmentally enhanced detention facility could also provide recreational, health, and educational benefits. Instead of using the typical fescue grasses, the remaining portions of the structure should be planted with warm season grasses or the following mix: Spring/Summer Mixture, May 1 - Sept. 15 Fall/Winter Mixture, Sept. 15 - April 30 Browntop millet 20 lbs/a Rye grain 120 lbs/a Korean lespedeza* 20 lbs/a Korean lespedeza* 20 lbs/a Shrub lespedeza 1 lb/a Shrub lespedeza 1 ib/a Switchgrass 10 lb/a Partridge pea 10 lb/a * On slopes less than 3:1 use Korean lespedeza On slopes greater than 3:1 use Crown Vetch or Sericea lespedeza (not preferred) Add one of the following to the above mixture Crown Vetch 5 lbs/acre Ladino Clover 5 lbs/acre Lime & fertilize disturbed areas according Alfalfa 5 lbs/acre to NCRS soil test and recommendations. (Note: Mowing should be limited to February I - April 1 and should only occur as needed to prevent tree growth on the dam or other areas. Mowing on a 2-3 year schedule should suffice.) Mill Creek Odell Sch Hwy.doc. Page 3 02/21/00 Trees and shrubs (1 year bare root seedlings) should be planted randomly at a minimal rate of 100 trees per acre on the top and upper portions of the structure and at a minimal rate of 150 per acre around the normal water elevation and littoral shelf area. The following list of tree species may assist in providing habitat benefits: Loblolly Pine* Red Cedar Black Gum American Holly Dogwood Hickory Sumac White Oak Willow Oak Red Maple** Swamp Chestnut Oak Viburnum Green Ash Ironwood Black Cherry Water Oak Persimmon Silky Dogwood Other species may be utilized depending on site requirements and availability. Pines* should not exceed 15% of the reforestation. No more than 20% of the tree species will be of a single species. An 80% success rate is acceptable over five years. Large or fast growing trees like Sycamore and Maple** may not be appropriate around detention facilities. The above recommendations should be considered for the multiple benefits that they can provide to the community and to the environment. Contributing to wider diversity of habitats around detention facilities will elevate aquatic and terrestrial biodiversity as well as provide multiple biological functions and benefits in urbanized settings. These areas may be limited in size yet still function as small ecosystems that can support amphibians, lizards, mammals, and birds. Initial costs for environmental enhancement of detention structures should not be prohibitive and the long-term maintenance costs should be reduced, as constant mowing would not be necessary in the naturalized areas. Initially, it may be advantageous to have basic sketches and planting schedules submitted for review prior to implementation of these detention facility enhancement practices. Thank you for the opportunity to review and comment on this project. If you have any questions regarding these comments, please contact me at 336/769- 9453.
