Length to width ratios should be 3:1 or greater. (Barfield, et al., 1981, pp. 426-429; Florida DEP, 1982, pg. 6-289). b. If the basin is used as a sediment trap during construction, all sediment deposited during construction must be removed before normal operation begins. C. Aquatic vegetation should be included for a wetland type detention basin (Maryland DNR, March 1987; Schueler, 1987, Chapter 4 and 9). A minimum ten foot wide shallow sloped shelf is needed at the edge of the basin for safety and to provide appropriate conditions for aquatic vegetation (Schueler, 1987). This shelf should be sloped 6:1 or flatter and extend to a depth of 2 feet below the surface of the permanent pool (Shaver and Maxted, DNREC, 1994). A list of suitable wetland species and propagation techniques are provided in Schueler (1987) and Maryland DNR (1987). d. An emergency drain (with a pipe sized to drain the pond in less than 24 hours) should be installed in all ponds to allow access for riser repairs and sediment removal (Schueler, 1987). 0 1 0 I 4 Table 1.1 Surface Area to Drainage Area Ratio For Permanent Pool Sizing For 85% Pollutant Removal Efficiency in the Piedmont °OO Jy - ?1 5 Notes: Numbers given in the body of the table are given in percentages.

Basin shape should minimize dead storage areas and short circuiting. Length to width ratios should be 3:1 or greater. (Barfield, et al., 1981, pp. 426-429; Florida DEP, 1982, pg. 6-289). b. If the basin is used as a sediment trap during construction, all sediment deposited during construction must be removed before normal operation begins. C. Aquatic vegetation should be included for a wetland type detention basin (Maryland DNR, March 1987; Schueler, 1987, Chapter 4 and 9). A minimum ten foot wide shallow sloped shelf is needed at the edge of the basin for safety and to provide appropriate conditions for aquatic vegetation (Schueler, 1987). This shelf should be sloped 6:1 or flatter and extend to a depth of 2 feet below the surface of the permanent pool (Shaver and Maxted, DNREC, 1994). A list of suitable wetland species and propagation techniques are provided in Schueler (1987) and Maryland DNR (1987). d. An emergency drain (with a pipe sized to drain the pond in less than 24 hours) should be installed in all ponds to allow access for riser repairs and sediment removal (Schueler, 1987). a t G 4 Table 1.1 Surface Area to Drainage Area Ratio For Permanent Pool Sizing For 85% Pollutant Removal Efficiency in the Piedmont °pO --)D oU ZZ 1-x(0 - 1 -5Suk 5 Notes: Numbers given in the body of the table are given in percentages.

Land Design, Inc. 1700 East Blvd Charlotte, NC 28203 Subject: South Park DWQ Project No. 990801 Mecklenburg County Dear Mr. Vogle: The Wetlands Unit staff reviewed the stormwater management plans for the subject project and determined . that additional information is necessary to complete the technical review process. The required additional information is as follows: Side Slopes The basin side slopes must be no steeper than 3:1. The side slopes adjacent to the retaining wall and below the permanent pool must be no steeper than 3:1 (horizontal to vertical). Please provide a cross section of the retaining wall area on the engineering plans. Vegetative Shelf A gently sloped (6:1 or flatter) vegetative shelf around the perimeter of the pond is typically required. You had mentioned during our conversation today that you would prefer to create an equal amount of vegetative shelf in certain areas of the pond, but that the shelf would not completely encircle the perimeter of the pond. This proposal seems reasonable from a water quality perspective. Please specify this on the engineering plans. Division wetlands unit staff will strive to complete a final technical review within 10 working days of receipt of the requested information. If you have any questions or would like to discuss this project, please contact me at (919) 733-9584. Also, please note that the NCDENR Stormwater Besi Management Practices Manual, April 1999, and other documents and information can be downloaded from the Wetlands Unit web site at http://h2o.ehnr.state.nc.us/ncwetlands/.

Shields, of Trammell Crow Company, I am requesting confirmation of eligibility to flood ±350 if of streams and fill -E- 4561f of streams with small areas of adjacent wetlands for the construction of a _1.70 acre stormwater treatment pond and symphony park. The stormwater pond will be integrated into the symphony park as an water feature amenity. Currently there are no stormwater treatment facilities treating runoff from the parking lots and adjacent urban areas. The pond will be designed to treat approximately 60 acres of surface from the mall and adjacent urban areas. Due to existing conditions the stormwater treatment facility cannot serve approximately 30 acres of the existing mall site (See the attached memo/report dated February 18, 1999, which summarizes the meetings with the USACE and NCDWQ in Raleigh on January 11, 1999). Background The project site is located in rapidly developing SouthParli area of Charlotte, NC. Current land use is commercial and office complexes. there are approximately 0.35 acres of jurisdictional surface waters and wetlands on the project site. There are approximately 955 if of streams which have important aquatic function. Ali fill material will be unpolluted and appropriate measures to control sedimentation and erosion will be employed. Streams which will not be disturbed will be protected during constriction from damage due to construction traffic, drainage and other forms of disturbance. As required the proposed pond, and remaining streams will be protected by restrictive covenants or similar mechanisms. The following sections present the results of the environmental planning reviews of the project site and a description of the impacts and proposed minimization and mitigation measures. S1: AEK4RY OF WATERS OF THE U_ S. 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. Dec 18 00 11:44a Leonard Rindner 704 847 0185 W. Steve Chapin - USACE, Mr. John R. Dorney, Mr. Mike Parker - NCDWQ Page 3, June 1, 1999 Preliminary data gatherir a 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 wand hydrology were be identified as described in the manual. The wetlands on this site can be describe as Palustrine Forested Broad - Leaved and Scrub/Shrub Temporarily Flooded and Seasonally Flooded. The site is within a drainage area of unnamed headwater tributaries of Little Sugar/Briar Creek (Water Classification - C). p.13 Vegetation The forested headwater wetland areas and riparian areas are dominated by Facultative Wet and Facultative species. Trees include green ash, alder, red maple, sweetgum, sycamore, willow oak, hornbeam. Understory and herbaceous strata includes silky dogwood, alder, spicebush, smilax, microstegium, sedges, soft rush, poison ivy.. Where the soils are more saturated Obligate species such as black willow are present. ?I2 is Sails The site includes Monacan (Mo) soils. These soils are map units which may have inclusions of hydric soils according. to the Sort Conservation Service (now Natural Resource Conservation Service), Technical Guide-Section II-A-2, June 1991. Z oiogv The wetland areas on this site are the result of a surface runoff a high seasonal water table, and stormwater discharges.

Minimizatio% and Mitigation Due to the economic, engineering, safety, and spatial requirements of a development of this magnitude, large coudauous areas musi be graded for roads,.building pads, and parking. However the following avoidance and minimization efforts and measures have been taken: Positive response to the recommendations and expected comments by the WCDWO and the USAGE incorporate stormwater treatment facilities. Best Management Practices will also 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) Preeonstruction meetings d) Vehicular access will be restricted to specific areas to avoid disturbance to adjacent wetlands and natural areas to be preserved, e) Methods to prevent short term impacts will be inspected regularly and maintained during construction ofthe project, fl Wetlands to be preserved will be clearly marked prior to construction to prevent accidental damage to wetlands. The contractors will be held responmrble for unauthorized wetland damage not permitted according to plans and specifications. Preconstruction meetings shall be held if necessary with representatives ofthe USACE and the NCDWQ. g) Short term construction impactC primarily stream sedimentation will affect aquatic habitat, however thus will be minimized to the extent practicable to promote rapid recovery. h) 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. i) 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 krwosed COIII?} 1Satn*o MitiioAfinn A mitigations plan is proposed for a "no net loss" of wetland and stream habitat, value, and function to the extent feasible orrthis site. TnaVoidable impacts to streams by r •• a gmd ?e_pronosedto be miti?at bT, rQ W Program where required Stream impacts by flooding will be mitigated by the protection of the remaning channels and the development of a forebay/littoral zone in connection with the new pond. The buffers on the remaining channels are proposed to be a minimum 35' wide, barricaded with silt fence. Buffers may exceed this width in many locations. Areas within the buffers which may be cleared due to grading requirements will be revegetated with riparian trees, shrubs, and groundcovers, to match adjacent conditions. The remaining streams on the project -site appear to be in excellent to good condition and will be protected by buffers. To meet restoration mitigation requirements for stream impacts by grading, the developer is proposing to contribute $57,000 to the North Carolina Wetland Restoration Program (456 if X 5125! It) to mitigate for stream impacts. Dec; 18 00 11:45a Leonard Rindner 704 847 0185 p.15 Mr. Steve Chapin - USACE, Mr. John R. Domey, Mr. Mike Parker - NCDWQ Page.5, June 1, 1999 STORcb WATER MANAGEMENT PIAN A Stormwater Management Plan will be designed and implemented for the project to meet the 401 Water Quality Certification requirements. Stonnwater management becomes necessary when increasing. the impervious area within an existing natural area. The planners will utffize information and guidelines provided by the North Carolina Department of Environment, Health, and Natural Resources Water Quality Section in developing this stormwater wetland. A wet detention basins small be the primary treatment system for stormwater runo$ from paved surfaces and landscaping oh commercial, office, business, and institutional parcels. The wet detention basins will be designed. to attenuate the fast inch of rainfall over a 24 hour period from approximately 50 acre of urbanized land within the ponds drainage area. 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. 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:l?e? Table I in the Stormwater $ecr lt?anggement thct;?ec NrD m ro„r io- PROTEC77ON FROM FUTURE DEMOPMENT The preserved wetlands and streams will be protected from future impacts by the applicant or by a group designated by the applicant for this purpose. Development of these areas will be deed restricted in accordance with restrictive covenants which will be developed for approval by the USACE and/or NCDWQ. TBREATENED 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 Schweinitz's sunflower (Helianthus schweinitzii) and the Carolina heelsplitter (Mecklenburg County). Schweinitz's sunflower thrives in full sun characteristic of succession fields, margins, and forested openings. Based on a site reconnaissance, habitat conducive to support hw ini 'c » flov r i not iLgkent in the nrg>JW 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 U5 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. 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. Dec 18 00 11:45a Leonard Rindner. 704 847 0185 p.16 Mr. Steve Chapin - USACE, Mr_ John R Dorney, Mr. Mike Parker - NCDWQ Page 6, June 1, 7999 CULTURAL RESOURCES The project site is urbanized and bounded by contemporary commercial and office developments. No standing structures were encountered on the project site. AQUA77CHABITAT - The aquatic systems in the project area consist of wetlands and intermittent tributaries of Briar Creep. A variety of wildlife is supported by these systems including mammals, birds, reptiles, amphibians, $sh, insects, mollusks, and drustaceans. 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 went 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. Aquatic resources are expected to be enhanced through, the development of a 1.70 acre pond with related littoral zone and forebay. CONCLUSION The SouthPark Mall expansion project 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 and creative .planning has chosen to balance the site's economic viability with its environmental value and permitability. The Baal of the Site Plan and Mitigation Plan is to help balance the environmental consequences of this development by creating a beneficial aquatic resource that will help maintain or minimize degradation of waters of the U.S. downstream of the project and through enhancement of remaining streams. 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.

Based on a meeting on-site with Steve Chapin of the United States Army Corps of Engineers (USACE), the wetland and stream delineation was verified as accurate. Jurisdictional Waters of the.U.S. are also subject to regulatory requirements in Section 404 and Section 401 of the Clean Water Act. The confirmed delineation was surveyed and is being utilized for planning and permitting purposes. 2. The stream was determined to have "important" aquatic value. Current regulations prevent the loss of more than 500 linear feet of "important" stream channels or more than 3 acres of wetlands by Nationwide Permit 426. Impacts over these thresholds would require the more complex Individual Permit Review. Based on current USACE policy, impacts to streams from flooding are not calculated on a linear foot basis. To use Nationwide Permit 926, pre-construction notification (PCN) to the U.S. Army Corps of Engineers (USACE) and the North Carolina Division of Water Quality (NCDWQ) is not required if impacts are less than 1/3'acre of waters of the U.S. (streams and wetlands) and/or less than 150 linear feet of stream beds and are above headwaters and if no other Nationwide Permits are required. Pre-construction notification is required for any impacts to streams more than 150 linear feet by the NCDWQ. If the impacts are above these thresholds (important or unimportant) an application is required to the USACE and the NCDWQ. If, commercial, business, office, industrial, and similax land uses causes impacts greater than 113 acre of Waters of the U.S., or more than 150 linear feet of streams than a stormwater treatment pond(s) will be required by the NCDWQ as a condition of the permit. Dec 18 00 11s58a Leonard Rindner 704 847 0185 p.24 Memorandum - Southpark Mall Wetland / Stream Permitting, Page 2 February 18, 1999 3. The USACE has agreed in concept that impacts to the stream by flooding for the purposes of creating a pond to meet the NCDWQ 401 Water Quality Certification conditions will be eligible for Nationwide Permit #26. However, impacts to the stream other than by flooding must be less than 500 linear feet.. If impacts to streams are over 150 linear feet due to activities other than flooding, mitigation will be required by the NCDWQ and the USAGE. Based on current policy, it appears unlikely that mitigation will be required by the USACE and the NCDWQ for the flooding impacts since the purpose of the pond is to meet the 401 Water Quality Certification requirements. 4. Based on a meeting with Mr. John Dorney of the NCDWQ on January 11, 1999, he endorsed the concept of utilizing the stream area to create a storm water management/detention facility that will also serve as an amenity. Based on the discussions, he agreed that the area to be treated by the facility will include approximately sixty acres (thirty acres of on-site drainage and approximately thirty acres of off-site drainage) from -primarily roads and parking areas. Drainage from the remaining sixty acres of the mall site, that currently by-passes the proposed pond area through a culvert under Morrison Drive, will not be required to be treated due to the difficulties and complexities of tying into existing urban condition. 5. Wet detention basins shall be utilized as 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 Water will be released over a 2 to 5 day period Discharge velocity will'be less than five efs. 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 Bet Management Practices TICDENR November 1995. The proposed solution provides an urban amenity while minimizing further degradation of water quality downstream as a consequence of this project. I have found both the USAGE and especially the NCDWQ very interested arid. supportive of the proposed. solution. Let me know if you have any questions.

Field Office 151 Patton Avenue - Room 143 Asheville, NC 28801 - 5006 Re: Soathpark Mall - Symphony Park - Action Id. 199931050 Dear Mr. Chapin: On behalf of Mr. Coy Shields of Trammell Crow Company, I am writing you to confirm our conversations regarding the additional stream mitigation requirements described in the nationwide permit verification. As you are aware, the developer has already paid $57,000 dollars into the North Carolina Wetland Restoration Program. Also, in addition to the pond and surrounding areas being a public amenity, the pond itself will be designed to facilitate storm water treatment according to the North Carolina Storm Water Best Management Guidelines, 1999. Buffers will protect undisturbed areas of the stream and the pond design will include a forebay, as required. The project will also comply with an approved Sedimentation and Erosion Control Plan. In order to meet the remaining mitigation requirements, the developer is proposing to participate or contribute to the enhancement of a segment of tributaries to Little Sugar Creek, and/or a segment of Little Sugar Creek itself. Little Sugar Creek traverses through very urbanized areas in Charlotte and has been and is subject to severe degradation. The City of Charlotte is also involved in several projects along Little Sugar Creek through Storm Water Services, in an effort to improve Little Sugar Creek. The anticipated enhancement primarily includes the clean-up urban debris from the creek and areas along the banks, such as trash, shopping carts, plastic, and tires. This will enhance wildlife habitat, remove pollutants, and stream flow. We appreciate your involvement in the environmental review and planning of this project. Please contact me if you have any questions or require additional explanation. Thank you for your consideration. Ldonard S.

Dorsey Division of Water Quality - NCDENR Environmental Science Laboratories 4401 Reedy Creek Road Raleigh, NC 27607 Re: SouthPark 11 xpaansion Charlotte Merk County No rth Carolina-Nationwide Permit #26 Dear Sirs: On behalf of my client, Mr. Coy E. Shields, of Trammell Crow Company, I am requesting confirmation of eligibility to flood ±350 If of streams and fill ± 4561f of streams with small areas of adjacent wetlands for the construction of a ±1.70 acre stormwater treatment pond and symphony park. The stormwater pond will be integrated into the symphony park as an water feature amenity. Currently there are no stormwater treatment. facilities treating runoff from the parking lots and adjacent urban areas. The pond will be designed to treat approximately 60 acres of surface from the mall and adjacent urban areas. Due to existing conditions the stormwater treatment facility cannot serve approximately 30 acres of the existing mall site (See the attached memo/report dated February 18, 1999, which summarizes the meetings with the USACE and NCDWQ in Raleigh on January 11, 1999). Background The project site is located in rapidly developing SouthPark area of Charlotte, NC. Current land use is commercial and office complexes. There are approximately 0.35 acres of jurisdictional surface waters and wetlands on the project site. There are approximately 955 if of streams which have important aquatic function. All fill material will be unpolluted and appropriate measures to control sedimentation and erosion will be employed. Streams which will not be disturbed will be protected during construction from damage due to construction traffic, drainage and other forms of disturbance. As required the proposed pond, and remaining streams will be protected by restrictive covenants or similar mechanisms. The following sections present the results of the environmental planning reviews of the project site and a description of the impacts and proposed minimization and mitigation measures. SUADMRY OF WATERS OF THE U.S Meth- odoto?' 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. Mr. Steve Chapin - USACE, Mr. John R. Dorney, Mr. Mike Parker - NCDWQ Page 3, June 1, 1999 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 were be identified as described in the manual. General WeLAnd Cia t Finn and n4•crrir??i n The wetlands on this site can be describe as Palustrine Forested Broad - Leaved and Scrub/Shrub Temporarily Flooded and Seasonally Flooded. The site is within a drainage area of unnamed headwater tributaries of Little Sugar/Briar Creek (Water Classification - C). Ye etrrtion The forested headwater wetland areas and riparian areas are dominated by Facultative Wet and Facultative species. Trees include green ash, alder, red maple, sweetgum, sycamore, willow oak, hornbeam. Understory and herbaceous strata includes silky dogwood, alder, spicebush, smilax, microstegium, sedges, soft rush, poison ivy.. Where the soils are more saturated Obligate species such as black willow are present. H is oily The site includes. Monacan (Mo) soils. These soils are map units which may have inclusions of hydric soils according, to the Soil Conservation Service (now Natural Resource Conservation Service), Technical Guide-Section H-A-2, June 1991. I??rologv The wetland areas on this site are the result of a surface runof, a high seasonal water table, and stormwater discharges.

The plan and commitments made in this report reflect a positive response to the preliminary discussions, 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. There has been a positive response to the recommendations and expected comments by the NCDWO and the USA CZ Mr. Steve Chapin - USACE, Mr. John R. Dorsey, Mr. Mike Parker - NCDWQ Page 4, June 1, 1999 Avoidance. Minimization and Mitigation Due to the economic, engineering, safety, and spatial requirements of a development of this magnitude, large contiguous areas must be graded for roads,.building pads, and parking. However the following avoidance and minimization efforts and measures have been taken: Positive response to the recommendations and expected comments by the NCDWO and the USAGE. incorporate stormwater treatment facilities. Best Management Practices will also 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) Preconstruction meetings d) Vehicular access will be restricted to specific areas to avoid disturbance to adjacent wetlands and natural. areas to be preserved. e) Methods to prevent short term impacts will be inspected regularly and maintained during construction of the project. f) Wetlands to be preserved will 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 NCDWQ. g) Short term construction impacts, primarily stream sedimentation will affect aquatic habitat, however this will be minimized to the extent practicable to promote rapid recovery. h) 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. i) 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. Proposed Co .1 ensaWry Mitigation A mitigation plan is proposed for a "no net loss" of wetland and stream habitat, value, and function to the extent feasible orrtbis site. Unavoidable impacts to stream by adi are nronosed to be mitigated bTv, buffers around the remaining streams and u iiration of the North arolina WetaadA RrctnratGnn Program where reanired. Stream impacts by flooding will be mitigated by the protection of the remaining channels and the development of a forebay/littoral zone in connection with the new pond. The buffers on the remaining channels are proposed to be a minimum 35' wide, barricaded with silt fence. Buffers may exceed this width in many locations. Areas within the buffers which may be cleared due to grading requirements will be revegetated with riparian trees, shrubs, and groundcovers, to match adjacent conditions. The remaining streams on the project site appear to be in excellent to good condition and will be protected by buffers. To meet restoration mitigation requirements for stream impacts by grading, the developer is proposing to contribute $57,000 to the North Carolina Wetland Restoration Program (456 if X $125! If) to mitigate for stream impacts. Mr. Steve Chapin - USACE; Mr. John R. Dorsey, Mr. Mike Parker - NCDWQ Page-5, June 1, 1999 STORMWA TER MAIVA GEM ENT PL4N A Stormwater Management Plan will be designed and implemented for the project to meet the 401 Water Quality Certification requirements. Stormwater management becomes necessary when increasing the impervious area within an existing natural area. The planners will utilize information and guidelines provided, by the North Carolina Department of Environment, Health, and Natural Resources Water Quality Section in developing this stormwater wetland. A 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 will be designed to attenuate the first inch of rainfall over a 24 hour period from approximately 60 acre of urbanized land within the ponds drainage area. 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. 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 7 t in the Stormwater Beet Management '*acticec I`T ENRg November, 1995 PROTECTION FROM FUTURE DEVELOPMENT The preserved wetlands and streams will be protected from future impacts by the applicant or by a group designated by the applicant for this purpose. Development of these areas will be deed restricted in accordance with restrictive covenants which will be developed for approval by the USACE and/or NCDWQ. 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 Schweinitz's sunflower (Helianthus sehweinitzii) and the Carolina heelsplitter (Mecklenburg County). Schweinitz's sunflower thrives in full sun characteristic of succession fields, margins, and forested openings. Based on a site reconnaissance, habitat conducive to support Schweini z'c unfln?yer is not sent in the elect 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 occuf on this site. Luty r-rutcuteO ne ies 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. Mr. Steve Chapin - USAGE, Mr. John R Dorney, Mr. Mike Parker - NCDWQ Page 6, June 1, 1999 CULTURAL RESOURCES The project site is urbanized and bounded by contemporary commercial and office developments. No standing structures were encountered on the project site. AQUATIC HABITAT The aquatic systems in the project area consist of wetlands and intermittent tributaries of Briar 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. 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. Aquatic resources are expected to be enhanced through the development of a 1.70 acre pond with related littoral zone and forebay. CONCLUSION The SouthPark Mali expansion project 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 and creative 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 creating a beneficial aquatic resource that will help maintain or minimize degradation of waters of the U.S. downstream of the project and through enhancement of remaining streams. 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.

PW Environmental Planning Consultant 3714 Spokeshave Lane Landscape Architecture Matthews, NC 28105 Land Planning Tele: (704) 846-0461 Fax (704) 847-0185 Date: February 18, 1999 To: Brad Davis Dale Stewart Meg Connolly Richard Petersheim Kevin Vogel From: Len Rindner Subject: Wetland / Stream Permitting - outhpark Mall Wetland Delineation and Permitting Issues 1. Based on a meeting on-site with Steve Chapin of the United States Army Corps of Engineers (USACE), the wetland and stream delineation was verified as accurate. Jurisdictional Waters of the .U.S. are also subject to regulatory requirements in Section 404 and Section 401 of the Clean Water Act. The confirmed delineation was surveyed and is being utilized for planning and permitting purposes. 2. The stream was determined to have "important" aquatic value. Current regulations prevent the loss of more than 500 linear feet of "important" stream channels or more than 3 acres of wetlands by Nationwide Permit 926. Impacts over these thresholds would require the more complex Individual Permit Review. Based on current USACE policy, impacts to streams from flooding are not calculated on a linear foot basis. To use Nationwide Permit #26, pre-construction notification (PCN) to the U.S. Army Corps of Engineers (USACE) and the North Carolina Division of Water Quality (NCDWQ) is not required if impacts are less than 1/3 acre of waters of the U.S. (streams and wetlands) and/or less than 150 linear feet of stream beds and are above headwaters and if no other Nationwide Permits are required. Pre-construction notification is required for any impacts to streams more than 150 linear feet by the NCDWQ. If the impacts are above these thresholds (important or unimportant) an application is required to the USACE and the NCDWQ. If commercial, business, office, industrial, and similar land uses causes impacts greater than 1/3 acre of Waters of the U.S., or more than 150 linear feet of streams than a stormwater treatment pond(s) will be required by the NCDWQ as a condition of the permit. Memorandum - Southpark Mall Wetland / Stream Permitting, Page 2 February 18, 1999 3. The USACE has agreed in concept that impacts to the stream by flooding for the purposes of creating a pond to meet the NCDWQ 401 Water Quality Certification conditions will be eligible for Nationwide Permit #25. However, impacts to the stream other than by flooding must be less than 500 linear feet.. If impacts to streams are over 150 linear feet due to activities other than flooding, mitigation will be required by the NCDWQ and the USAGE. Based on current policy, it appears unlikely that mitigation will be required by the USACE and the NCDWQ for the flooding impacts since the purpose of the pond is to meet the 401 Water Quality Certification requirements. 4. Based on a meeting with Mr. John Domey of the NCDWQ on January 11, 1999, he endorsed the concept of utilizing the stream area to create a storm water management/detention facility that will also serve as an amenity. Based on the discussions, he agreed that the area to be treated by the facility will include approximately sixty acres (thirty acres of on-site drainage and approximately thirty acres of off-site drainage) from primarily roads and parking areas. Drainage from the remaining sixty acres of the mall site, that currently by-passes the proposed pond area through a culvert under Morrison Drive, will not be required to be treated due to the difficulties and complexities of tying into existing urban condition. 5. Wet detention basins shall be utilized as 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. Water will be released over a 2 to 5 day period Discharge velocity will be less than five cfs. 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 The proposed solution provides an urban amenity while minimizing further degradation of water quality downstream as a consequence of this project. I have found both the USACE and especially the NCDWQ very interested and. supportive of the proposed solution. Let me know if you have any questions.

(Barfield, et al., 1981, pp. 426-429; Florida DEP, 1982, pg. 6-289). b. If the basin is used as a sediment trap during construction, all sediment deposited during construction must be removed before normal operation begins. C. Aquatic vegetation should be included for a wetland type detention basin (Maryland DNR, March 1987; Schueler, 1987, Chapter 4 and 9). A minimum ten foot wide shallow sloped shelf is needed at the edge of the basin for safety and to provide appropriate conditions for aquatic vegetation (Schueler, 1987). This shelf should be sloped 6:1 or flatter and extend to a depth of 2 feet below the surface of the permanent pool (Shaver and Maxted, DNREC, 1994). A list of suitable wetland species and propagation techniques are provided in Schueler (1987) and Maryland DNR (1987). I An emergency drain (with a pipe sized to drain the pond in less than 24 hours) should be installed in all ponds to allow access for riser repairs and sediment removal (Schueler, 1987).
