This modification is attributed to changing economic considerations, and very difficult existing soil conditions. The revised plans depict wetland impacts of less than 1/3 acre in headwaters. We would appreciate at your earliest convenience a confirmation letter of eligibility or reissuance of a General Water Quality Certification to utilize Nationwide Permit #26 to impact + 0.30 acres to develop this project for our record Thank you again for your consideration and approval of our previous submittal.

As a result of this change approximately 0.90 acre of the area originally designated as a stormwater wetland will need to be relocated. The function of this area will be replaced in the form of a created stormwater wetland, wet detention pond, or combination in the area depicted on the plan. It will tie in with the portion of the stormwater treatment area that remains the same as originally planned. As discussed the treatment area will also be designed to handle the drainage area (including off-site) which utilizes wetland area "K." Thank you for meeting with me to discuss this necessary change. Please let me know if you have any questions. Thank you for your consideration. cere , J Leonard S. Rindner, PWS Environmental Planning Consultant cc.

PROJECT LOCATION AND DESCRIPTION The proposed Lakemont West Project is located on approximately 88 acres in southwest Mecklenburg County, North Carolina. The tract is approximately two miles west of the Exit 90 on Interstate 77 and within two miles of the I485 Outer-Belt now under construction. This site is ideally situated to take advantage of and enhance the rapid economic growth related to the industrial, and transportation distribution facilities in southwest Charlotte especially along Carowinds Boulevard. Due to the rapid and expected growth in population and employment opportunities, York Road (NC Highway 49) will be widened to four lanes. The immediate project area is developing commercial and residential. The site is heavily wooded with extremely dense areas of old field succession. Current land use in the vicinity is mixed with multi-family and large single family subdivisions, commercial, office, and other transportation/distribution facilities. The tract is currently zoned for use as industrial (I-1). Due to the site planning constraints (earthwork) of a development of this type, large contiguous areas must be graded as building pads and parking. While nearly all of the wetlands on this site can be characterized as high quality, the largest wetland areas which are located in the Steele Creek floodplain, will not be impacted by the proposed development. As shown on the Nationwide Permit (NWP) applications, the developer seeks approval to ' impact approximately 0.82 acres of jurisdictional waters in headwaters. All fill material will be unpolluted and appropriate measures to control sedimentation and erosion will be employed. Wetlands which will not be disturbed will be protected during construction from damage due to construction traffic, drainage and other forms of disturbance. A total of 1.42 acres of high quality bottomland hardwood wetlands will be preserved ' and protected by buffers. In addition, the hydrology to large areas of the floodplain will be enhanced utilizing the stormdrainage system, potentially restoring or creating wetlands in this "marginal" non-wetland floodplain. The following sections present the ' results of the environmental planning and regulatory reviews of the project site and a description of the impacts and proposed minimization and mitigation measures. The undisturbed wetland areas and the mitigation sites will be preserved by the applicant or ' by a group designated by the owner for this purpose. 4 C 1 Mst alt IL v H ? cl- a1 N - 1 - w L ?469 I ? 1 4, ?7?1-?77?iT,3i?7T?,•? ?._ 00, o LOCATION MAP i 128 (,H C X e?z SOUTHERN` '- i PF,0 S 4? ulk, PFOIA PFDIGt?

The US Fish and Wildlife Service has identified two endangered species - Schweinitz's sunflower (Helianthus schweinitzii), and the Carolina heelsplitter (Lasmigona decorata). Schweinitz's sunflower thrives in full sun characteristic of successional fields, margins, and forested openings. A review of ' USGS (Ft. Mill Quad) Maps at the Natural Heritage Program at NCDEHNR in Raleigh did not indicate any endangered species previously identified on the site. ' Except for small areas of mature forest, the site in general is in very dense old field succession from former agricultural activity and is dominated by cedar, sweetgum, winged elm, blackberry, honeysuckle, and dense overgrowth. Since Schweinitz's sunflower is known to occur in lredell soils, I was accompanied by Mr. John T. Soule of Dr. Jim Matthews (UNCC) H.A.R.P. organization during the wetland delineation process. John T. Soule is one of Dr. Matthew's primary field investigators. Neither John T. Soule nor I identified Schweinitz's sunflower or habitat conducive for it's survival. ' 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 not expected to occur on this site. ' State Protected Species The Carolina Darter (Etheostoma collis) is a fish that inhabits small streams such as those found in the project area. 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. 5 LI IV. CULTURAL RESOURCES The project site was heavily disturbed from agricultural and clear-cutting activities. There are no indications of any existing structures on the project site or adjacent areas. ' The Office of State Archaeology (OSA) and the Survey and Restoration Branch (SRB) of the NC Department of Cultural Resources - State Historic Preservation Office (SHPO) was visited in March, 1996 and again on June 11, 1996, to review existing mapping on ' the USGS Quad maps, if any. The purpose of this review was to determine if there was previously identified sites in the project area. Based on the review of the maps at the OSA and at the SRB, no previously identified or surveyed sites are currently indicated on the maps within the project area. L LI 6 V. AQUATIC HABITAT 1 The aquatic systems in the project area consist of below headwater and headwater wetlands and intermittent tributaries of Steele Creek. 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. Fish S cies Fish species that are most likely to occur in the project area include (but not limited to) high back, creek and blue head chub, green and red breasted sunfish, pirate perch, ' tessellated darter, white sucker and rosyside dace. Crustaceans and Shellfish Cambrus and Procambrus crayfish are expected to inhabit areas near intermittent tributaries. Indigenous and Asiatic clams, and snails are likely to inhabit the ponded areas and are not expected to substantially inhabit intermittent tributaries. ' Amphibians and Reptiles Amphibians and reptiles that are likely (but not limited to) to occur near streams include ' dusky and two-lined salamanders, spring peepers, bullfrog, mud turtle, skink, black snake, and copperhead. Existing habitat is expected to remain in natural areas close to the banks and in undisturbed wetland areas. Short term construction impacts, primarily stream sedimentation will affect aquatic habitat, however this will be minimized to the extent practicable to promote rapid ' recovery. 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. 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. VI. JURISDICTIONAL WATERS OF THE UNITED STATES 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. Typical observation plots were located along transects perpendicular to the drainageway direction to observe and record potential indicators. This information was then recorded on Data Form - l which indicates specific information about the typical plot. The upper boundary was assumed to occur between the non-wetland and wetland plots. Due to the complexity of this site, numerous additional test plots and borings were conducted when necessary to increase the accuracy of the delineation. Once the wetland / ' non-wetland determination was made, the characteristics at that point were utilized to determine the wetland boundary between transects and additional test plots through visual observation. I I w The wetland boundary was marked in the field by Leonard S. Rindner, Environmental Planning Consultant, and was reviewed, field adjusted, and verified by the USACE (Steve Lund) on April 8, 1996. The approved wetland boundary is marked in the field with pink and yellow flagging. This delineation between upland and wetland was then surveyed by a registered surveyor (ESP Associates, P.A.) to determine the actual wetland extents for submittal to the USACE for confirmation, planning, and potential permitting purposes. 8 I?

The wetlands have formed in perched water table conditions, in flat to nearly level areas, along intermittent tributaries, and in the Floodplain over an extremely dense clayey subsoil layer often associated with inclusions in Monacan, and Iredell soils. L Steele Creek is in the Sugar Creek Sub-basin of the Catawba River Basin. The Water Classification is "C" : Aquatic life propagation and.survival, fishing, wildlife, secondary recreation, and agriculture. The extent of the Jurisdictional Waters were determined in the field following the Routine On-Site Determination Method as defined according to the 1987 Corps of Engineers Wetland Delineation Manual and verified by the U.S. Army Corps of Engineers. The extent of the Jurisdictional Waters of the U.S. on this 88 acre site is 2.34 acres.

WETLANDS PERMITTING AND MITIGATION The developer has actively pursued professional planning input to develop this project while maintaining strong sensitivity to environmental concerns. Preliminary planning involved site analysis and consideration of environmental and regulatory issues. Topography, natural features and systems, circulation network, site organization, open space and development requirements, and environmental issues were considerations in designing the overall plan. Once the final extents of the wetland areas were determined, a very strong effort, as depicted on the land plan, was made to adapt the schematic land plan to avoid and minimize impacts to wetlands. During the schematic planning stage meetings were held with representatives of the US Army Corps of Engineers, North Carolina Division of Environmental Management, to review schematic planning efforts including unavoidable impacts, and minimization and mitigation measures. The plan and commitments made in this report reflect a positive response to the preliminary negotiations, determinations, and concerns of the regulatory agencies. Except for temporary construction and development impacts, we believe that the proposed project will not cause significant impacts to the ecological functions or values of Jurisdictional Waters of the U. S. Avoidance and Minimization Through planning efforts, filling many of several large contiguous areas of wetlands has been avoided. Significant wetlands areas will not be impacted in the Steele Creek floodplain. The following is a summary of items which have already been incorporated into the Master Plan to lessen impact to wetlands: 1. Reduction in the sizes of Buildings 2, 4, 6, and 8 by 27,200 square feet each for a total of 108,000 square feet(an 8 1/2% reduction in the overall square footage). 2. Modification of the configuration for the Building 8 parking area to preserve Wetland Area "N". 3. Reduction of parking areas along the rear portions of Building 2, 4, 6, and 8 to preserve additional areas for mitigation and storm water treatment. 4. Reduction of formal landscaped areas between the buildings and parking to minimize space requirements and impacts to natural areas. 5. Design of multiple building sites with stepped finish floor elevations to allow better transitions to existing grades. 6. Incorporation of "shared" service areas to further reduce impacts to the natural areas along Steele Creek. 10 I 7. Modifications to the site plan to minimize impacts to Area "F" to the extent feasible. As recommended by the NCDEM a buffer area as depicted on the plans is provided to ' protect these wetland areas from encroachment. Best Management Practices will also be employed to minimize impacts to the remaining Jurisdictional Waters. BMP's include: ' - Siltation Barriers Sediment Traps and Diversion Ditches Barricades to define construction limits to sensitive sites and to protect trees ' - Preconstruction meetings Other methods as appropriate ' Vehicular access will be restricted to specific areas to avoid disturbance to adjacent wetlands and natural areas to be preserved. Methods to prevent short term impacts will ' be inspected regularly and maintained during construction of the project. Wetlands to be clearly marked prior to construction to prevent accidental damage to wetlands. The contractors will be held responsible for unauthorized wetland damage not permitted according to plans and specifications. Preconstruction meetings shall be held if necessary with representatives of the USACE and the NCDEM. ' Proposed Impacts The development of the project will require an estimated 0.82 Acres of impacts to Jurisdictional Waters of the U.S. utilizing NWP #26. I 1 General Description of Impacts Utilizing NWP #26 (Headwaters & Isolated Waters) - Impacts to Intermittent Tributaries ± 0.15 Acres - Impacts to Wetlands + 0.67 Acres Total Jurisdictional Waters Impacted Utilizing NWP#26 + 0.82 Acres A mitigation plan has been developed to provide for a "no net loss" of wetland habitat, value, and function to the extent feasible on this site. The type of mitigation shown on the plan are described below generally fall under the category of Creation and Enhancement. Many areas of the floodplain that will be utilized may have been wetlands in the past and portions may qualify as Restoration. This is expected to occur within a four to five acre riparian zone in the floodplain. The goal of this plan is to preserve and protect the existing wetlands and surface waters, enhance riparian habitat, and create/restore wetlands, if possible of approximately one (1.0) acre that may have occurred along the floodplain of Steele Creek. This is approximately a 2:1 mitigation ratio for ± 0.5 acre of impacts to Areas "F" (partial), "K", and "L", which were determined to be of high value. 11 I Steele Creek has been channelized in order to withstand the increasing amounts of storm- water from the surrounding urban areas of Charlotte. This has hydrologically isolated portions of the adjacent floodplain by reducing the frequency and duration of water inundation and saturation within the proposed mitigation area. The loss of the wetland ' hydrology has also been enhanced by ditching and by deposition of sediments from disturbed areas upstream. The USACE confirmed that these areas are not considered jurisdictional wetlands. Particular areas were reviewed in the field utilizing existing r topographic maps to evaluate the sites suitability for the proposed mitigation. Large areas of this zone were carefully evaluated during the wetland delineation process and were nearly determined to be jurisdictional wetlands. The areas are subject to flooding especially in winter and early spring and are relatively flat and forested. Drainage from these areas has been enhanced by ditching to Steele Creek. ' The management plan will rely on increasing the frequency and duration of saturation, flooding, and ponding within the mitigation area to support or begin to restore wetland hydrology. This will be accomplished by directing stormwater to these areas to these areas as well as for stormwater treatment. The water will be diffused utilizing plunge pools, level spreading devices, and/or other methods to reduce discharge velocity. Then the water will be directed into and within the mitigation site by a series of flow paths that are manipulated by small berms and excavations. Manipulation of the flow in the existing ditch outlet from these areas may also be required. A existing riparian berm and parallel sewer line exists along Steele Creek. This will reinforce the flooding and ponding regime as well as provide access for monitoring. ' The wetland mitigation area has a diverse population of hydrophytic vegetation that will likely withstand the increased duration of saturation and ponding in the winter and early spring. Dominant species include green ash, sycamore, boxelder, elm, red maple, silky dogwood, privet, and sweet gum. Herbaceous species currently include honeysuckle, poison ivy, microstegum, and others. It is expected that with increased saturation some vegetation may suffer, such as redcedar, black cherry, eleagnus, privet, and other upland r species. However it is expected that willow, cottonwood, green ash, and other herbaceous species would succeed naturally. Additional vegetation monitoring will be conducted ' following issuance of the permit to determine the need for additional planting in the future to enhance the habitat values. The use of BMP's will be used as appropriate to minimize unavoidable impacts. Impacts from hazardous materials and other toxins to fish, such as fuels, will be avoided by not permitting staging areas to be located near tributaries or wetlands. Also, measures shall ' be taken to prevent live or fresh concrete from coming into contact with waters until the concrete has hardened. Employment of strict erosion and sediment control procedures will be specified to avoid impacts to water quality. ' 12 Existing wetlands and surface waters and buffer areas will be protected from erosion and sedimentation during construction and installation of the mitigation sites. Control structures such as sedimentation traps, siltation barriers, and/or at a minimum silt fence will be utilized as necessary. minimization and Mitigation Summary - Plans and overall scope of project modified to extent feasible. - Wetland buffers and retaining riparian habitat along Steele Creek - Strict adherence to an approved sedimentation control plan and other best management practices. - Restoration/Creation goal of 1.0 acres of wetlands in the floodplain, and/or enhancing riparian habitat. 13 I " ?

STORMWATER MANAGEMENT PLAN A Stormwater Management Plan will be designed and implemented for the project to meet the 401 Water Quality Certification requirements. To help offset the loss of the ' wetlands value and reduce the potential nutrient impacts downstream the developer proposes utilizing the non-wetland floodplain and to potentially create/restore storm drainage wetlands as the primary treatment system. Properly designed storm drainage ' wetlands/filtration areas have been proven to be a viable solution to reduce pollution. Establishing and maintaining a natural, forested, low maintenance ecosystem will reduce the volume of runoff, and thereby reduce erosion and pollutants coming from an area of ' more intensive land use to a water body. The reduction of erosion and pollutants occurs through natural mechanisms such as deposition, infiltration, adsorption, absorption, ' filtration, and decomposition. Natural forested areas have the capacity for collecting and storing nutrients and the canopy protects the soil from erosion. If additional area is necessary for treatment based on calculations during the design process, stormwater wet ' detention ponds or other methods will be utilized to supplement the proposed treatment plan. ' Stormwater Management Plan Concgpts Stormwater management becomes necessary when increasing the impervious area within an existing natural area. The impact of the increased runoff and reduction of natural ' filtration will be analyzed with respect to the capacity and stability of natural channels and the presence of environmentally sensitive areas. The pre and post-development runoff will be determined and used as the basis of stormwater management techniques. ' Special consideration will be given to avoiding erosion and degradation of environmentally sensitive areas, wetlands, and surface waters. ' The Stormwater Management Plan will include: A. Utilization of natural floodplain and wetland mitigation areas where ' possible for stormwater treatment. B. Wet Detention Basins, if necessary, to supplement stormwater wetlands. Basins ' if necessary will attenuate 1.0 inch of rainfall over a 24 hour period for high density sites including office, commercial and business uses. C. Riser outflow structures to maintain a pool and encourage filtration. ' D. Directing runoff into natural areas and wetland/biofilters to treat runoff before entering surface waters. E. Maintaining natural and planted areas between the development and ' Jurisdictional Waters. ' 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. ' 14 IX. PLANS AND MONITORING Detailed plans for the mitigation areas will be further articulated from the plans included in this document. These plans will be submitted to the USACE and the NCDEM for approval. Plans will include : Site Preparation Requirements Vegetation Requirements Tracking and Monitoring Requirements A monitoring program will be developed to monitor the mitigation areas to include: Vegetation Parameters Species Composition and Abundance Survival - Growth Monitoring of vegetation will be conducted on a semi-annual basis according to the following general procedures. A. Measure growth, species diversity, advise on removal of invasive species. B. Establishment of a representative sample observation plot of at least 30' radius to record the number and species of each surviving woody stem and the percent aerial cover of the three most dominant species. C. Within the 30' radius area, a 10' radius area will be established to record the three dominant herbaceous species. D. Periodic site visits will be conducted for maintenance, aesthetic purposes, and possible modifications to increase survival rates. E. Recommendations regarding planting enhancement, if necessary. E. Field data will be recorded on a monitoring data form and submitted along with representative photographs in a annual monitoring report. This will be submitted to the USACE and the NCDEM. At the end of the third year a report will be prepared for review and to determine the need for future monitoring or modifications. Annual Progress Reports will be prepared which summarizes the data collected in the field and notes trends. Photographs at fixed stations will be taken to document the trends and changes occurring at the sites. These reports will be furnished to the Corps of Engineers and the North Carolina Division of Environmental Management. After the third year of monitoring, a summary report and as-builts will be furnished to the USACE and NCDEM for review and discussion regarding compliance of the project with conditions of the permit. 15 ' The data collected during the monitoring period will be utilized to evaluate the success of the mitigation areas. The success criteria will be as follows: ' - Soil saturation within 12 inches of the surface for a minimum of approximately 12 consecutive days during the early part of the growing season. ' - Establish at least one hydrology indicator per the 1987 USACE Wetland Delineation Manual in the sample plot or match adjacent riparian habitat surroundings Establish at least one hydric soil characteristic or match adjacent riparian ' habitat surroundings. These vegetative, soil, and hydrological characteristics must be met to determine success ' of the wetland mitigation sites. ' If the mitigation is determined to be unsuccessful contingency plans will be developed for review and implemented. Schedule Grading and installation of water control structures where applicable will be conducted ' concurrently with project construction and are expected to begin in the summer of 1996. Vegetation planting and installation is expected to be conducted in the dormant season of January-February 1997 and spring for herbaceous materials. 16 8.0 CONCLUSION ' The 88 acre development will provide enormous economic benefits to the region. The goal of the Site Plan and Mitigation Plan is to help balance the environmental ' consequences of this intense development by restoring and creating beneficial wetland or riparian habitat and enhancing and preserving the Jurisdictional Waters of the U.S. remaining on the site. The undisturbed wetland areas and the mitigation sites will be ' preserved by the applicant or by a group designated by the owner for this purpose. They will be managed as a wetland system of high value. 17
