INTRODUCTION This project consists of constructing a new shopping center located along Julia obdin Rowan County, NC. The site parcel is 28.11 acres and is under the jurisdiction of Rowan County and NCDENR. This report, in conjunction with the construction plans, is meant to demonstrate that the design is consistent with the rules and regulation of this jurisdiction. 2. EXISTING CONDITIONS 2.1 Site Characteristics Currently the site is undeveloped and mostly wooded. The site sheet drains west to an unnamed tributary to Town Creek. There is approximately 0.16 acres of wetlands on the property as well as two streams, however, they will not be impacted as a result of the development. 2.2 Soil Information The soil map in Appendix A depicts the various soil types found on site. The soils around the subject site are noted as Appling sandy loam and Cecil sandy clay loam in hydrologic soil group B (60% of developed area) and Helena sandy loam in hydrologic soil group D (40% of developed area). 2.3 Hydrology The total drainage area used for stormwater calculations is 21.53 acres (4.63 acres of undeveloped area and 1.95 acres of pervious bypass area per the table in section 3.1 is omitted). Using a curve number of 55 for good wooded areas in hydrologic soil group B, and 77 for good wooded areas in hydrologic soil group D, the weighed curve number for the site is 64. TR-55 method was used to calculate a time of concentration of 38 minutes. The predevelopment flow rates for the site are listed below: 1-year, 24 hour storm: 3.55 cfs 10-year, 24 hour storm: 21.4 cfs 25-year, 24 hour storm: 31.4 cfs 100-year, 24 hour storm: 48.9 cfs The hydrographs are provided in Appendix B. 2.4 Floodplains & Floodways Floodplain information was compiled from Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) number 3710565800J effective June 16, 2009. Based on these maps, the site is not in a designated floodplain. STORMWATER MANAGEMENT REPORT 3 BERRY ENGINEERS LLC 3555 KEITH ST NW, SUITE 109, CLEVELAND, TN 37312 TEL, 423-790-5880 3. PROPOSED STORMWATER MANAGEMENT SYSTEM 3.1 Design Conditions The 28.11 acre site will be initially developed with a 141,000 S.F. shopping center and associated parking area with 7.59 acres reserved for future development. The development is designed for a total impervious area of 16.80 acres. The initial construction will include 9.71 acres of impervious area (of which 0.10 acres bypasses the pond at the driveways), 5.24 acres of grassed area (of which 1.95 acres bypasses the pond around the perimeter of the site), and 4.63 acres of undisturbed area which will not drain to the detention pond (excluded from the calculations). A future roadway extension, with 0.94 acres of impervious area (of which 0.10 acres will bypass the pond) is also planned for. The future development parcels are designed for an additional 6.15 acres of impervious area and 1.44 acres of grassed area. A curve number of 98 was used for the impervious area, 61 for the grassed areas in HSG B, 80 for the grassed areas in HSG D, and 77 for the wooded undeveloped areas (HSG D). The weighted curve number for the developed portion of the site draining to the detention pond is 90. The time of concentration is 10 minutes for the developed site. Runoff from the development is conveyed through a storm sewer system and discharge into a wet detention pond to meet the NCDENR water quality requirements and peak discharge requirements. The wet detention pond has 3:1 side slopes, a forebays at the pond inlet, and a 10' vegetated shelf around the normal water elevation. The permanent pool elevation is 745.00, the bottom of the pond is 735.00 (736.00 sediment cleanout elevation), and the top of bank is 752.50. Exhibit B depicts the development area and the below table provides a summary of the areas. Land Use Area Developed Parcels (Lots 2, 7, 8, & 9) Future Development Parcels (Lots 1, 3, 4, 5, & 6) Proposed Impervious (to pond) 9.61 acres 0 acres Proposed Pervious (to pond) 3.29 acres n/a Future Impervious (to pond) 0.84 acres 6.15 acres Future Impervious (bypasses pond) 0.10 acres 0 acres Future Pervious (to pond) n/a 1.44 acres Proposed Impervious (bypasses pond) 0.10 acres 0 acres Proposed Pervious (bypasses pond) 1.95 acres 0 acres Undeveloped (bypasses pond) 4.63 acres n/a Total 20.52 acres 7.59 acres 3.2 Stormwater Treatment The NCDENR requires stormwater to be treated with a system that provides at least 85% TSS removal. A wet detention pond will provide this removal rate if it is designed in accordance with the NCDENR Stormwater BMP manual. The achieve 85% TTS removal efficiency, the permanent pool must be sized in accordance with Table 10-1 of the BMP manual. The total drainage area for the pond is about 21.53 acres with 16.80 acres of impervious area (78% impervious) and the average Permanent Pool Depth is 6.26 feet. From Table 10-1, the required STORMWATER MANAGEMENT REPORT 4 BERRY ENGINEERS LLC 3555 KEITH ST NW, SUITE 109, CLEVELAND, TN 37312 TEL. 423-790-5880 surface area to drainage area ratio is 2.10% (85% impervious interpolation) and the provided ratio is 2.44%. NCDENR requires new developments to provide treatment for the first one inch of runoff by providing a drawdown of the volume between 48-120 hours. Using the equation in section 3.3.1 of the BMP Manual, the required treatment volume is 58,770 cubic feet. The provided treatment volume between elevations 745.00 and 747.50 is 68,700 cubic feet. 3.3 Post Development Peak Discharges Rowan County requires the post development discharge rates to be at or below the existing predevelopment discharge rates for the 1-year and 10-year, 24 hour storm events. An outlet control device was placed at the detention pond to control the peak discharge from the site. The 25-year and 100-year storms were also checked. A hydrologic analysis was performed to demonstrate that post development flows from the site are less the predevelopment flows. The hydrographs for the proposed conditions are attached in Appendix B, and the results are listed below: 1-year, 24 hour storm: 10-year, 24 hour storm: 25-year, 24 hour storm: 100-year, 24 hour storm: 3.4 Operation & Maintenance 3.0 cfs (Pond elevation = 747.9') 20.6 cfs (Pond elevation = 749.9') 28.2 cfs (Pond elevation = 750.7') 79.3 cfs (Pond elevation = 751.6') The pond is designed with an extra one foot of depth to allow for sediment accumulation. This sediment shall be removed once it reaches elevation 736.0. It is anticipated that the forebay will need sediment removal more often than the main pond area. Since the pond is shared between multiple property owners, an operation and maintenance agreement will be established between all parties. The maintenance required includes but is not limited to mowing, clearing debris from inlets, trash pickup, erosion inspections, stabilization of the side slopes and vegetated shelf, and monitoring the offsite discharge points.

The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. http://Nvebsoilsurvey.nres.tisda.gov/app/WebSoilSLirvey.aspx 9/27/2014 TDOT DESIGN DIVISION DRAINAGE MANUAL January 1, 2010 Cover Type and Hydrologic Condition Fully Developed Urban'Areas (v.egetation'established) ° N. for So)I Group : ; A t3 : :C D Open sace lawn, parks, golf courses, cemeteries, etc.)`: Poor condition (grass cover < 50%) 68 79 86 89 Fair condition (grass cover 60% to 75%) 49 69 79 64 Good condition (grass cover> 75%) 39 61 74 80 Impervious areas: Paved parking lots, roofs, driveways, etc. (excluding right-of-way) 98 98 98 98 Streets and roads: Paved; curbs and storm sewers (excluding right -of -way) 98 98 98 98 Paved; open ditches (including right-of-way) 83 89 92 93 Gravel (including right-of-way) 76 85 89 91 Dirt (including right-of-way) 72 82 87 89 Urban districts: Commercial end business 85% average impervious area 89 92 94 95 Industrial 72% average Impervious area 81 88 91 93 Residential districts by average I size: 1/8 acre or less (town houses) 65% average impervious area 77 85 90 92 114 acre 38% average Impervious area 61 75 83 87 1/3 acre 30% average Impervious area 57 72 81 86 1/2 acre 25% average impervious area 54 70 80 85 1 acre 20% average impervious area 51 68 79 84 2 acres 12% average Impervious area 46 65 77 82 Developing urban areas: Nevily graded areas (pervious areas only, no vegetation)77 86 1 91 94 For Idle lands, CN's are determined using cover types similar to those In Tel 4A-3 Table 4A-1 Runoff Curve Numbers for Urban Areas Reference: USDA, Urban Hydrology for Small Watersheds (1986) (See following page for notes) 4A-18 TDOT DESIGN DIVISION DRAINAGE MANUAL January 1, 2010 cover, Type and Description,'' Hydrologic,:.

INTRODUCTION This project consists of constructing a new shopping center located along Julianc%,ad in Rowan County, NC. The site parcel is 26.30 acres and is under the jurisdiction of Rowa%',i-t�nty and NCDENR. This report, in conjunction with the construction plans, is meant to dem6Et ntp that the design is consistent with the rules and regulation of this jurisdiction. )^9R 2. EXISTING CONDITIONS 2.1 Site Characteristics Currently the site is undeveloped and mostly wooded. The site sheet drains west to aV*,, unnamed tributary to Town Creek. There is approximately 0.16 acres of wetlands on the property as well as two streams, however, they will not be impacted as a result of the development. 2.2 Soil Information The soil map in Appendix A of the stormwater report depicts the various soil types found on site. The soils around the subject site are noted as Appling sandy loam and Cecil sandy clay loam in hydrologic soil group B (60% of developed area) and Helena sandy loam in hydrologic soil group D (40% of developed area). 2.3 Hydrology The total drainage area used for stormwater calculations is 21.80 acres (4.50 acres of undeveloped area is omitted). Using a curve number of 55 for good wooded areas in hydrologic soil group B, and 77 for good wooded areas in hydrologic soil group D, the weighed curve number for the site is 64. TR-55 method was used to calculate a time of concentration of 38 minutes. The predevelopment flow rates for the site are listed below: 1-year, 24 hour storm: 3.6 cfs 10-year, 24 hour storm: 21.7 cfs 25-year, 24 hour storm: 31.8 cfs 100-year, 24 hour storm: 49.5 cfs The hydrographs are provided in Appendix B of the stormwater report. 2.4 Floodplains & Floodways Floodplain information was compiled from Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) number 3710565800J effective June 16, 2009. Based on these maps, the site is not in a designated floodplain.

PROPOSED STORMWATER MANAGEMENT SYSTEM 3.1 Design Conditions The 26.30 acre site will be initially developed with a 151,500 S.F. shopping center and associated parking area with 4.30 acres reserved for future development. The development is designed for 13.00 acres of impervious area (of which 0.10 acres bypasses the pond at the driveways), 4.05 acres of grassed area (of which 2.20 acres bypasses the pond around the perimeter of the site), and 4.50 acres of undisturbed area which will not drain to the detention pond (excluded from the calculations). A future roadway extension, with 0.45 acres of impervious area (of which 0.10 acres will bypass the pond) is also planned for. The future development parcels are designed for an additional 3.50 acres of impervious area and 0.80 acres of grassed area. A curve number of 98 was used for the impervious area, 61 for the grassed areas in HSG B, 80 for the grassed areas in HSG D, and 77 for the wooded undeveloped areas (HSG D). The weighted curve number for the developed portion of the site draining to the detention pond is 93 and the weighted curve number for the bypass area is 79. The time of concentration is 10 minutes for the developed site. Runoff from the development is conveyed through a storm sewer system and discharge into a wet detention pond to meet the NCDENR water quality requirements and peak discharge requirements. The wet detention pond has 3:1 side slopes, a forebay$ at the pond inlet, and a 10' vegetated shelf around the normal water elevation. The permanent pool elevation is 745.00, the bottom of the pond is 736.00, and the top of bank is 752.50. Exhibit B of the stormwater report depicts the development area and the below table provides a summary of the areas. Land Use Area Developed Parcels Future Development Parcel Proposed Impervious (to pond) 12.90 acres 0 acres Proposed Pervious (to pond) 1.85 acres n/a Future Impervious (to pond) 0.35 acres 3.50 acres Future Impervious (bypasses pond) 0.10 acres 0 acres Future Pervious (to pond) n/a 0.80 acres Proposed Impervious (bypasses pond) 0.10 acres 0 acres Proposed Pervious (bypasses pond) 2.20 acres 0 acres Undeveloped (bypasses pond) 4.50 acres n/a Total 22.00 acres 4.30 acres 3.2 Stormwater Treatment The NCDENR requires stormwater to be treated with a system that provides at least 85% TSS removal. A wet detention pond will provide this removal rate if it is designed in accordance with the NCDENR Stormwater BMP manual. The achieve 85% TTS removal efficiency, the permanent pool must be sized in accordance with Table 10-1 of the BMP manual. The total drainage area for the pond is about 19.40 acres (86% impervious) and the average Permanent STORMWA TER MANAGEMENT REPORT BERRY ENGINEERS, LLC 3555 KEITH ST NW, SUITE 109, CLEVELAND, TN 37312 TEL. 423-790-5880 Pool Depth is 6.1 feet. From Table 10-1, the required surface area to drainage area ratio is 2.22% and the provided ratio is 2.36%. NCDENR requires new developments to provide treatment for the first one inch of runoff by providing a drawdown of the volume between 48-120 hours. Using the equation in section 3.3.1 of the BMP Manual, the required treatment volume is 58,000 cubic feet. The provided treatment volume between elevations 745.00 and 747.50 is 60,800 cubic feet. 3.3 Post Development Peak Discharges Rowan County requires the post development discharge rates to be at or below the existing predevelopment discharge rates for the 1-year and 10-year, 24 hour storm events. An outlet control device was placed at the detention pond to control the peak discharge from the site. The 25-year and 100-year storms were also checked. A hydrologic analysis was performed to demonstrate that post development flows from the site are less the predevelopment flows. The hydrographs for the proposed conditions are attached in Appendix B of the stormwater report, and the results are listed below: 1-year, 24 hour storm: 5.6 cfs' (Pond elevation = 748.6') 10-year, 24 hour storm: 20.5 cfs (Pond elevation = 750.5') 25-year, 24 hour storm: 30.5 cfs (Pond elevation = 751.4') 100-year, 24 hour storm: 100 cfs (Pond elevation = 752.0') 'The post development flow for the 1-year storm exceeds the predevelopment flow rate, but this is only due to the 2.2 acres of pervious bypass area and the 0.1 acres of impervious bypass that occurs at the driveways. The flow rate leaving the detention pond is 1.9 cfs during the one-year storm. 3.4 Operation & Maintenance The pond is designed with an extra one foot of depth to allow for sediment accumulation. This sediment shall be removed once it reaches elevation 736.0. It is anticipated that the forebay will need sediment removal more often than the main pond area. Since the pond is shared between multiple property owners, an operation and maintenance agreement will be established between all parties. The maintenance required includes but is not limited to mowing, clearing debris from inlets, trash pickup, erosion inspections, stabilization of the side slopes and vegetated shelf, and monitoring the offsite discharge points.

Deed restrictions and protective covenants are necessary to ensure that the development maintains a built -upon area consistent with the design criteria used to size the stormwater control facility. 1, Geor a Alexandris acknowledge, affirm and agree by my signature below, that I will cause the o lowing deed restrictions and covenants to be recorded prior to the sale of any lot within the project known as Rowan Summit Shopping Center 3. 4. 5. 6. The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit Number S 1J31 d as issued by the Division of Water Quality under the Stormwater Management Regulations. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to maintain compliance with the stormwater management permit. These covenants are to run with the land and be binding on all persons and parties claiming under them. .Ykr The covenants pertaining to stormwater may not be altered or rescinded witCi the e�cpress written consent of the State of North Carolina, Division of Water Quality. Alteration of the drainage as shown on the approved plan may not take plaq�yyith0 , concurrence of the Division of Water Quality. uG 1 ,y�^^ The maximum allowable built -upon area per lot is as defined below: Hy`''. ,;, ?Q/s Lot Area IIIM Lot q (Acres) BUA (S.F.)

All runoff from the built -upon areas on the lot must drain into the permitted system. This may be accomplished through a variety of means including roof drain gutters which drain to the street, grading the lot to drain toward the street, or grading perimeter sweles to collect the lot runoff and directing them into a component of the stormwater collection system. Lots that will naturally drain into the system are not required to provide these additional measures. 8. The owner of each lot, whose ownership is not retained by the permittee, is required to submit a separate stormwater permit application to the Division of Water Quality and receive a permit prior to construction. 9. The project and each lot will maintain a 30** foot wide vegetated buffer between all impervious areas and surface waters.

To operate, maintain and repair the Real Property in the same manner as was used prior to the Effective Date, reasonable wear and tear excepted, subject to Paragraph 12; 13.3. Not to enter into any lease, service contract or other contract which, following Closing, will be binding upon Purchaser or the Property without, in each instance, obtaining the prior written approval of Purchaser; 13.4.
