Ross, Jr., Secretary Department of Environment and Natural Resources Alan W. Klimek, P.E. Director Division of Water Quality August 1, 2002 Gregory Antemann Carolina Wetland Services 528 East Boulevard, Suite 101 Charlotte, NC 28203 Subject: Dear Mr. Antemann: Bellasera DWQ Project No. 020637 Mecklenburg County The Wetlands Unit staff reviewed the stormwater management plans for the subject project and determined that the plans cannot be approved as designed. The following must be addressed: Discharge Locations The plans indicate that there are several stormwater discharges that will occur directly into the existing stream before receiving treatment. Please revise the plans to eliminate these discharges where possible. 2. Permanent Water Quality Pool, Temporary Water Quality Pool The plans indicate that pond #3, which is jurisdictional, will be retrofitted to one degree or another for stormwater management. Your correspondence indicates that there will be no grading within the basin. The plans provided do not clearly support this assertion since a retaining wall is proposed around the entire pond and no surrey has been conducted (according to your letter). The SA/DA ratio must be based on the average pond depth. Using an average pond depth of 3 feet and based on the information provided, the pond surface area proposed is adequate. However, since no survey was conducted to determine the depth of the pond how can the surface area be accurately determined? Also, what is the pre-construction (existing) elevation of the pond surface? This may be important in determining whether or not additional wetland impacts need to be accounted for as the result of flooding or draining. 3. Draw Down Orifice Diameter The diameter of the orifice must be sized to draw down the temporary water quality pool volume.in 48 to 120 hours. One.plan indicates that an orifice of three inches diameter will be provided. The other indicates that an opening of 3.76 feet by 0.5 feet will be provided. Please clarify. 4. SA/DA Ratio The SA/DA ratio must be appropriate for the actual impervious area (including any offsite impervious area) draining to the basin. Please specify the onsite impervious area expected as well as the offsite impervious area (based on reasonable built-out expectations. Reference NCDENR Stormwater Best Management Practices Manual, April 1999. 5. Forebay All stormwater wet detention basins are required to have a forebay(s) to facilitate TSS removal. If multiple forebays are proposed, the volume of the forebay should be proportional to the drainage area to the forebay. The aggregate forebay volume should be approximately 20% of the total basin volume. Reference NCDENR Stormwater Best Management Practices Manual, April 1999. Please revise the engineering plans to meet this requirement.

Inlet/Outlet Structure Location The inlet and outlet structures must be placed to minimize short circuiting and turbulence. A long flow path will help to maximize the settling efficiency of the water quality structure. The submitted design will be subject to short circuiting. This issue may be addressed through structure relocation, baffles, forebays, etc.. 7. Vegetative Shelf A vegetative shelf around the perimeter of the pond is required. The shelf shall be gently sloped (6:1 or flatter) and shall consist of native vegetation. 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.

WETUNDS GpOUP Subject: Bellasera Multi-Family Site Vt? TE "i'lITY SECTION Division of Water - DWQ#02-0637 Storm Water Management Plan Mecklenburg County, North Carolina Carolina Wetland Services Project No. 2002-0173 Dear Mr. St. John: Dewitt Corporation is submitting this Storm Water Management Plan (SWMP) as part of permitting requirements for commercial developments, which are proposing greater.than 30% impervious cover. A Nationwide Permit application for the Bellasera Multi-Family Site was previously submitted to the North Carolina Division of Water Quality (NCDWQ), and has been assigned DWQ Project No. 02-0637. The enclosed Storm Water Management Plan (SWMP) was prepared by Site Solutions, and has been designed to meet the required 85% removal of Total Suspended Solids. This plan proposes to utilize an existing on-site pond for the treatment of storm water. Please note the following alternatives to the typical design requirements: The basin side slopes are no steeper than 3:1- No survey has been performed to determine the precise topography of the existing pond. The pond will be drained to accommodate the re- construction of the dam. To avoid disturbance to the pond's existing vegetation communities no grading will take place within the basin. 2. A submerged and vegetated shelf of less than 6:1 and Vegetation to the permanent pool is specified - Existing woody and herbaceous vegetation growing around the pond will be maintained and/or replaced to satisfy this condition. Existing vegetation around the pond includes mature tag alder (Alnus serrulata), black willow (Salix nigra), and red maple (Acer rubrum). 528 East Boulevard, Suite 101 • Charlotte, NC 28203 • (704) 377-1822 Phone • (704) 377-6951 Fax www.carolinawetlandservices.com Bellasera Multi-Family Site July 17, 2002 Storm Water Management Plan CWS Proiect No. 2002-0173 3. The permanent pool depth is between 3 and 6 feet - The existing pond has a permanent pool depth of seven feet. 4. The forebay volume should be 20% of the total volume of the pond - No grading is being planned within the pond. An existing wetland area in the inlet to the pond will likely provide some pollutant removal functions. Please don't hesitate to call me if you have any questions regarding this SWMP. I can be reached at (704) 377-1822. Thanks for your time. Sincerely, Gre C. A, L temann, .W.S.

Please modify the document as appropriate.] The wet [wetland) detention basiin system is defined as the wet [wetland) detention basin, pretreatment including forebays and the vegetated filter if one is provided- Maintenance activities shall be performed as follows: 1. After every significant runoff producing rainfall event and at least monthly. a. Inspect the wet [wetland) detention basin system for sediment accumulation, erosion, trash accumulation, vegetated cover, and general condition. b. Check and dear the orifice of any obstructions such that drawdown of the temporary pool occurs within 2 to 5 days as designed. 2. Repair eroded areas immediately, re-seed as necessary to maintain good vegetative cover, mow vegetative cover to maintain a maximum height of six inches, and remove trash as needed. 3_ Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain proper functioning. 4. Remove accumulated sediment from the wet [wetland] detention basin system semi-annually or when depth is reduced to 75% of the original design depth (see diagram below). Removed sediment $hall be disposed of in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e. stockpiling near a wet (wetland) detention basin or stream, etc.). The measuring device used to determine the sediment elevation shall be such that it will give an accurate depth reading and not readily penetrate into accumulated sediments. When the permanent pool depth reads -7 11. 15 feet in the main pond, the sediment shall be removed. [For stormwater wetlands: If' the elevation of the marsh areas exceed the permanent pool elevation, the sediment should be removed to design levels. This shall be performed by removing the upper 6 inches of soil and stockpiling it. Then the marsh area shall be excavated six inches below design elevations. Afterwards the stockpiled soil should be spread over the marsh surface. The soil should not be stockpiled for more than two weeks.] When the permanent pool depth reads -?- feet in the forebay [and micro-pool], the sediment shall be removed, BASIN DIAGRAM (fill in the blanks) V Permanent Pool Elevation 7 a .O Sediment moval El.

The site is approximately 40 acres in size and is located within the Catawba River Basin. There are five on-site jurisdictional areas: Stream A, Stream B, Wetland AA, Pond A, and Pond B (Attachment A - Figure 3). This project's applicant, Dewitt Corporation, is proposing the construction of a multi-family residential development. Carolina Wetland Services (CWS) has been authorized to act as an agent in providing wetland permitting services for Dewitt Corporation in this matter (Attachment B). On behalf of Dewitt Corporation, CWS is submitting a Pre-Construction Notification application (Attachment C) with attachments in accordance with Nationwide Permit General Condition No. 13, and pursuant to Nationwide Permit No. 39. Site Solutions has been contracted to develop the Master Plan for the Bellasera Multi-Family Site. They have designed a site plan that incorporates the on-site wetlands and drainage features ' as amenities to be protected and enjoyed by the proposed community. Housing sites and attendant features will be positioned outside of jurisdictional waters to the maximum extent possible while still achieving the goals of the project. Unavoidable impacts to jurisdictional waters due to stream crossings have been reduced through the use of retaining walls. The jurisdictional waters impacted by this project include 46 linear feet of perennial channel, 0.02 acre (134 If) of unimportant intermittent channel, 0.02 acre of wetland, and 0.04 acre of pond ' (open water). To mitigate for these limited impacts, riparian buffers will be maintained along all undisturbed stream segments. Bellasera Multi-Family Site April 22, 2002 Nationwide Permit No. 39 Project No. 2002-0173 i i i i i i i i i i i i i i i Existing Conditions The Bellasera Multi-Family Site is located in Matthews, North Carolina, approximately 2,000 feet northeast of the junction of U.S. Highway 74 (Independence Boulevard) and Highway 51 (Matthews-Mint Hill Road) (Attachment A - Figures 1 and 2). The site is approximately 40 acres in size and is located within the Catawba River Basin. The following sections describe the existing conditions on the site. Current Land Use The majority of the site is wooded with a maintained area surrounding Pond A in the southern corner of the site. Dominant vegetation growing in the wooded areas includes: Virginia pine (Pinus virginiana), tulip poplar (Liriodendron tulipifera), red maple (Acer rubrum), white oak (Quercus alba), and sweet gum (Liquidambar styracifula). The presence of weedy species suggests that this area has been used for agricultural purposes in the past. Jurisdictional Delineation and Verification CWS's Gregg Antemann, Andrea Hughes, and Isaac Hinson delineated on-site jurisdictional waters of the U.S.1 on January 11, 2002 using the U. S. Army Corps of Engineers (USACE) - Routine On- site Determination Method. This method is defined in the 1987 Corps of Engineers Wetlands Delineation Manual2. Jurisdictional waters of the U.S. were classified according to recent North Carolina Division of Water Quality (NCDWQ)3 and USACE guidance. There are five jurisdictional areas within the project site: Stream A, Stream B, Wetland AA, Pond A, and Pond B (Attachment A - Figure 3). On-site jurisdictional waters are unnamed tributaries to Irvins Creek. Irvin Creek is located within the Catawba River Basin and is classified as "Class C" waters by the NCDWQ. Table 1 is a summary of on-site jurisdictional areas. A surveyed Wetland Delineation (Wetland Boundary Survey) and Jurisdictional Determination package was forwarded to the USACE and was verified (signed) on March 20, 2002 (Attachment A - Figure 3. Wetland Boundary Survey). 1 "Jurisdictional waters of the U.S." includes essentially all surface waters such as: all navigable waters and their tributaries, all interstate waters and their tributaries, all wetlands adjacent to these waters, and all impoundments of these waters. 2 Environmental Laboratory.

The upstream limit of Stream A begins approximately 100 feet north of Pond A and is evaluated to be unimportant intermittent. This portion of Stream A had weak riffle-pool sequences, channel braiding and a weak bankfull bench (Attachments C and D - SCP#1). There were rooted plants in the channel bed, leaf litter, and no signs of recent flow. This portion of Stream A rated a 17.5 out of a possible 71 points on the NCDWQ Stream Classification Form and has a drainage area of approximately 10 acres. A photograph of unimportant intermittent Stream A has been included as Attachment F - Photograph A. Approximately 265 linear feet of Stream A appears to be unimportant intermittent on site. At a two-foot nick point approximately 365 linear feet downstream from Pond A, Stream A becomes an important intermittent channel for approximately 300 linear feet. This portion of Stream A has moderate levels of riffle-pool sequences and sinuosity (Attachments C and D - SCP#2). There is a continuous bed and bank present with a saturated channel bottom and persistent pools. This portion of Stream A scored a 24 out of a possible 71 points on the NCDWQ Stream Classification Form and drains approximately 20 acres. A photograph of the important intermittent portion of Stream A has been included as Attachment F - Photograph B. 4 Acreage of unimportant intermittent channel was estimated based on an average ordinary high water width of three feet. 3 Bellasera Multi-Family Site April 22, 2002 Nationwide Permit No. 39 Project No. 2002-0173 Approximately 360 linear feet of Stream A is perennial. This portion of the stream exhibits strong stream sinuosity and a bankfull bench (Attachments C and D - SCP#3). Groundwater flow was observed on the day of the field investigation with an average width of four feet. Stream A rated a 34.5 out of a possible 71 points on the NCDWQ Stream Classification Form. This portion of Stream A has a drainage area of approximately 25 acres. Stream B flows north across the northeast corner of the site for approximately 105 linear feet. Stream B is an unimportant intermittent channel. This portion of Stream B exhibits weak riffle- pool sequences, channel substrate (coarse sand and clay), and channel braiding (Attachments C and D - SCP#4). This stream rated a 17 out of a possible 71 points on the NCDWQ Stream Classification Form and has a drainage area of approximately 5 acres. A photograph of this portion of Stream B has been included as Attachment F - Photograph C. Wetland Ratings Wetland AA is located at the confluence of Stream A and Pond B. This area is approximately 0.09 acre in size and was determined to be a wetland based on the presence of hydric soils, indicators of wetland hydrology, and the dominance of hydrophytic vegetation. Hydrophytic vegetation observed includes broomsedge (Andropogon virginicus), switch grass (Panicum rigidulum var. pubescens), tag alder (Alnus serrulata), black willow (Salix nigra), and various species of sedge (Carex spp.). A Routine On-Site Data Form for this wetland is included as Attachment E - DP#1 and a photograph is included as Attachment F - Photograph D. A Routine On-Site Data Form representative of adjacent upland areas has been included as Attachment E - DP#2. 4 ' Bellasera Multi-Family Site April 22, 2002 Nationwide Permit No. 39 Project No. 2002-0173 The on-site wetland area (Wetland AA) was evaluated utilizing the North Carolina Department ' of Environment and Natural Resources (NCDENR) Guidance for Rating the Values of Wetlands in North Carolinas. The evaluation and ratings of the on-site wetland area are based on: • Water Storage • Bank/Shoreline Stabilization • Pollutant Removal ' • Wildlife Habitat • Aquatic Life Value ' • Recreation and Education ' Wetland AA was classified as a forebay wetland and scored 35 out of a possible 100 points (Attachment G). This wetland exhibited strong bank/shoreline stabilization and wildlife habitat ' functions. During the development of a Storm Water Management Plan (SWMP), techniques to improve the pollutant removal functions of this wetland will be investigated. Ponds ' Pond A is located in the southern corner of the property and is approximately 1.03 acre in size. The perimeter of the pond is maintained grass. The water level of Pond A appeared to be lower than usual due to the local drought conditions. Asiatic clam (Corbicula fluminea) shells were ' abundant along the exposed shoreline of the pond. ' Pond B is located in the northern corner of the property and is fed by Stream A. This pond is approximately 1.66 acres in size. Wildlife use observed adjacent to or on this pond included beavers (beaver lodge), Canada geese (on pond), deer (tracks), and raccoons (tracks). These ponds will be modified to treat stormwater runoff. I I 5 NCDENR. Guidance for Rating the Values of Wetlands in North Carolina, January, 1995. 1 Bellasera Multi-Family Site April 22, 2002 Nationwide Permit No. 39 Project No. 2002-0173 I I I I I Agency Correspondence Cultural Resources A letter was forwarded to the State Historic Preservation Office (SHPO) on February 8, 2002, to determine the presence of any areas of architectural, historic, of archaeological significance that would be affected by the project. In a letter dated March 12, 2002, SHPO verified that there are no historic resources that would be affected by the project (Attachment I). Protected Species Correspondence, dated February 7, 2002, was forwarded to the North Carolina Natural Heritage Program (NCNHP) to determine the presence of any federally-listed or candidate endangered or threatened species or critical habitat within the permit area of the proposed project. The following species are known to exist within the Matthews, NC, and Mint Hill, NC, quadrangles: Carolina birdfoot-trefoil (Lotus helleri), eastern creekshell (Villosa delumbis), eastern shooting star (Dodecatheon meadia var meadia), crested coralroot (Helaxectris spicata), Carolina darter (Etheostoma collis), Piedmont Aster (Aster mirabilis), and white wild indigo (Baptisia albescens). Correspondence from the NCNHP, dated February 14, 2002, indicates that there are no records of rare species, significant natural communities, or priority natural areas at or within a mile of the proposed site (Attachment I). During the field visit, no habitat for the aforementioned species was observed within the project area. In addition to the letter to the NCNHP, a letter was forwarded to the U.S. Fish and Wildlife Service (USFWS) on February 7, 2002. To date no response from this agency has been received. Based on the correspondence from the NCNHP, the presence of any federally protected species is unlikely. 6 ' Bellasera Multi-Family Site April 22, 2002 Nationwide Permit No. 39 Project No. 2002-0173 Purpose and Need for the Project Dewitt Corporation is planning a multi-family housing development on this project site. The ' purpose of this project is to provide housing in an area that is experiencing significant commercial growth. Making housing, retail, and office space available in the same community ' leads to a decrease in commuter congestion. In addition, multi-family housing allows for an increase in affordable home ownership opportunities while minimizing the area of land needed to be developed to accommodate this increase. As currently proposed, this site will provide 176 ' housing units. Construction is expected to begin during the summer of 2002. Project History There is no previous project history for this site. In the past, the surrounding area was a rural community that underwent minimal development. The area is now becoming a high-growth ' suburb of Charlotte and this project represents the first attempt to develop the proposed site. i i i i i i i i i Bellasera Multi-Family Site April 22, 2002 Nationwide Permit No. 39 Project No. 2002-0173 Avoidance and Minimization From the beginning of its design, the site plan for this project has been developed to avoid jurisdictional features to the maximum extent possible while still achieving the project's goal. The Site Plan is included as Attachment A - Figures 4-4d. Housing sites and attendant features were designed around the ponds (Pond A and B) and Stream A, providing access to these features and an adjacent nature trail as an amenity for the community residents. Key elements of the avoidance and minimization strategy include: • avoiding approximately 614 linear feet of important stream (Stream A) • avoiding approximately 0.02 acre (236 linear feet) of unimportant intermittent channel (Stream A and B) • avoiding 2.65 acres of ponds (Ponds A and B) • avoiding approximately 0.07 acre of wetlands (Wetland AA) This Site Plan avoids impacting 93% of on-site important stream channels. In addition, all crossings associated with the nature trail will be spanned to avoid addition channel impacts. The two road crossings will be designed to meet the USACE Wilmington Regional Condition that requires new culverts to be buried one foot below the existing streambed. Channel impacts associated with these crossings have been minimized to the maximum extent through the construction of retaining walls. Proposed Impacts to jurisdictional Waters The proposed development of the 40-acre Multi-Family Bellasera Site will result in unavoidable impacts to jurisdictional waters of the U.S. These impacts have been determined utilizing an overlay of the Wetland Boundary Survey and the proposed site plan. Approximately 0.01 acre (82 linear feet) of unimportant intermittent Stream B and 0.04 acre of Pond B will be impacted for the construction of multi-family housing units and attendant features (Attachment A - Figures 4a and b). Approximately 0.02 acre of Wetland AA will be impacted for the construction of a parking lot and road crossing (Attachment A - Figure 4c). Approximately 46 linear feet of perennial Stream A and 8 • Bellasera Multi-Family Site April 22, 2002 Nationwide Permit No. 39 Project No. 2002-0173 1 0.01 acre (52 linear feet) of unimportant intermittent Stream A will be impacted for road construction (Attachment A - Figure 4c and d). All totaled, this plan impacts approximately 46 linear feet of perennial channel, 0.02 acre (134 linear feet) of ' important intermittent stream channel, 0.02 acre of wetland area and 0.04 acre of open water.

Activities that will result in impacts to jurisdictional waters of the U.S. will be required to follow ' the General Conditions of the Nationwide Permits (Federal Register, Vol. 67, No. 10; January 15, 2002. Proposed Conceptual Compensatory Mitigation ' Due to the limited nature of these impacts, this project is proposing preservation of undisturbed ' stream channel and the maintenance of riparian buffers along undisturbed stream segments to mitigate for the 46 linear feet of perennial channel impacts. In addition to the preservation of on- site channels, two on-site ponds will be modified to improve their ability to treat storm water run- off. ' Bellasera Multi-Family Site April 22, 2002 Nationwide Permit No. 39 Project No. 2002-0173 7 1 Storm Water Management Plan To compensate for the loss of approximately 0.06 acres of ponds and wetlands, Ponds A and B will be retrofitted in order to provide increased flood attenuation, establish native vegetation, and provide an increased ability to filter storm water. Approximately 2.65 acres of open water habitat (Ponds A and B) will be improved. A vegetated littoral shelf capable of removing a variety of surface water pollutants will be created along the slopes of these existing ponds. This shelf will have a shallow slope and provide adequate zones for the establishment of wetland vegetation. Once retrofitted, Ponds A and B will be able to achieve the 85% Total Suspended Solids removal goal required by NCDWQ. Specific details of the Stormwater Management Plan are being finalized by Site Solutions. Once complete, this plan will be forwarded to the NCDWQ for approval. 10 1 .m'joaFm jox r-i Nmm C, n A O- C N C F.. yy NmC _ D II ?-?& C???? 9 ^Z?m z l 0 ° v _ w ? M ] j> N O m? ?

Impact Justification (Avoidance and Minimization) From the beeinnine of its desien. the site elan for this proiect has been developed to avoid jurisdictional features to the maximum extent possible while still achieving the project's goal. Housing sites and attendant features will be positioned around the Qonds (Pond A and B) and Stream A, providing access to these features and an adjacent nature trail as an amenity for the community residents. Key elements of the avoidance and minimization strategy include: avoiding 614 linear feet of important channel (Stream A), 0.02 acres (236 linear feet) of unimportant channel (Streams A and B). 2.65 acres of ponds, and 0.07 acres of wetland. Page 4 of 7 VIII. Mitigation I I i I I 1. This project is proposing preservation of stream channel and riparian buffer to mitigate for the 46 linear feet of perennial channel impacts. Buffers will be maintained adjacent to on-site channels to the maximum extent practicable. 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that you would like to pay into the NCWRP. Please note that payment into the NCWRP must be reviewed and approved before it can be used to satisfy mitigation requirements. Applicants will be notified early in the review process by the 401/Wetlands Unit if payment into the NCWRP is available as an option. For additional information regarding the application process for the NCWRP, check the NCWRP website at httn://h2o.enr.state.nc.us/M/index.htm. If use of the NCWRP is proposed, please check the appropriate box on page three and provide the following information: Amount of stream mitigation requested (linear feet): N/A Amount of buffer mitigation requested (square feet): N/A Amount of Riparian wetland mitigation requested (acres): N/A Amount of Non-riparian wetland mitigation requested (acres): N/A Amount of Coastal wetland mitigation requested (acres): N/A IX.
