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. I, Dominic A. Visconsi, Jr. , acknowledge, affirm and agree by my signature below, that I will cause the following deed restrictions and covenants to be recorded prior to the sale of any lot within the project known as Long Beach Crossing • 1. The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit Number 5\,4 I J Oiv I l , as issued by the Division of Water Quality under the Stormwater Management Regulations. 2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to maintain compliance with the stormwater management permit. 3. These covenants are to run with the land and be binding on all persons and parties claiming under them. 4. The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Water Quality. 5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence of the Division of Water Quality. 6. The maximum allowable built-upon area per lot is_see below square feet. *Note: If the BUA per lot varies, please substitute the following statement for the one above and provide a complete listing of the proposed BUA for each lot: The maximum built-upon area per lot, in square feet, is as listed below: Lot# BUA Lot# BUA Lot# BUA Lot# BUA 1 225,074 3 94,517 4 38,783 5 47,180 This allotted amount includes any built-upon area constructed within the lot property boundaries, and that portion of the right-of-way between the front lot line and the edge of the pavement. Built upon area includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate, coquina and parking areas, but does not include raised, open wood decking, or the water surface of swimming pools. 7. 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 swales 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 bu 0 ef�'aJ1,Impervious areas and surface waters. `� ....

Long Beach Crossing—SW8 140614 Dear Ms. Nelson: In response to your comment letter dated August 4, 2014 for the above referenced project we offer the following responses as shown in bold. 1. For drainage are 1,the Contech Stormfilter Supplement indicates that the provided storage volume is 18,984 ft3,however the calculations appear to indicate the storage volume is 21, 154 ft3 at an elevation of 12.2 ft within the storage basin. Please confirm the provided volume for drainage area 1 and provide calculations demonstrating the minimum required storage volume for the design storm and the adjusted volume. Response: The correct volume is 18,984 ft3;the temporary pool elevation was reduced to an elevation of 12.0'to minimize activation of the emergency spillway. The appropriate supplement, calculation and plan sheets have been revised and are included herein. 2. The revised plans appear to indicate that the inside slope of the wet detention pond associated with drainage area 2 is also slightly within the 30-foot vegetated buffer. Please confirm that this pond is designed in accordance with the recent guidance provided to clarify Section 2(b)(3)b.5 of Session Law 2008-211 and that the pond is located such that it extends no further into the vegetated buffer than the top of the embankment. 243 North Front Street Response: The wet pond associated with drainage area 2 has been Wilmington,NC 28401 revised to prevent the inside top of the embankment from crossing the 30- 910.343.1048 foot vegetated buffer. The appropriate supplement, calculation and plan sheets have been revised.

The supplement and temporary pool stage/storage table for the wet detention pond associated with drainage area 2 indicates that the surface area at an elevation of 8.5 was reduced slightly from the previous submittal. However the permanent pool information presented in the - associated stage/storage table does not seem to have been updated accordingly. Please confirm the permanent pool volume and surface areas presented in the stage storage tables and in the supplement. Response: The permanent pool information in the stage storage table and supplement has been updated for the wet detention pond associated with drainage area 2. 4. Please provide a level spreader/vegetated filter strip supplement for the level spreader proposed to provide equal or better treatment from drainage area 3. Response: The level spreader/vegetated filter strip supplement for drainage area 3 was originally included with the June 27,2014 submission. Please see attached copy of this supplement however the original signed documents should be in your file. 5. Please provide calculations to support the flow rates presented in the various supplements and confirm the information presented in the level spreader/vegetated filter strip supplement for drainage area 2. For instance,the level spreader/vegetated filter strip supplement for the design storm will be 9.876 cfs even though the wet detention pond supplement indicates the storage volume discharge rate will be 0.7 cfs. The 10-year storm even peak discharge is listed as being 9.193 cfs. Response: The values shown previously were discharge flows directly from the BMP as the supplement is worded. The supplement has been revised to only show the discharge entering the level spreader and not those flowing through the bypass structure. nEcEIvE ri Atri 11 2014 BY: S:\6523\0001\10-Comm\13-Comm with Regulatory Bodies\2014-08-08 RESPONSE LETTER to C Nelson NCDENR.doc MCKIM&CREED Ms. Christine Nelson August 11,2014 Page 3 6.

The southern curb line and the access entrance provided for Outparcel#4 appear to impact the required 30-foot vegetated buffer. Please confirm the location of the impervious area and demonstrate that the 30-foot vegetated buffer requirements for a redevelopment project are being met. Response: The entrance to outparcel #4 has been removed from the plans. The new location will be determined by the future owner of Outparcel #4 who will submit separately for stormzvater permitting. The driveway will be placed according to regulatory requirements at that time. 2. Section 2(b)(3)b.5 of Session Law 2008-211 does not allow wet detention basins to be located within the vegetated buffer. Additional clarification was provided for a different project that the top of the basin embankment could be located within the vegetated buffer but not the inside portion of the wet detention basin. The grading plan appears to indicate that the West Pond (Drainage Area 1) is located such that the wet detention basin vegetated shelf extends into the vegetated buffer. Please re-consider the 243 North Front Street wet detention basin design so that the wet detention basin extends no further into the vegetated buffer than the top of the embankment. Wilmington,NC 28401 910.343.1048 • Fax 910.251.8282 S:\6523\0001\10-Comm\13-Comm with Regulatory Bodies\2014-07-16 RESPONSE LETTER to C Nelson NCDENR.doc www.mckimcreed.com Ms. Christine Nelson July 28, 2014 Page 2 Response: Although conflicting written guidance was provided in March, the wet detention ponds have been shifted so that the interior edge of the top of the embankment does not encroach into the vegetated buffer. 3. Per the definition of a vegetated buffer in 15A NCAC 02H.1002(24), all discharges into an.d through the vegetated buffer must provide diffuse flow in order to protect surface waters from degradation. Please demonstrate how the pipe discharges and rip rap aprons meet the diffuse flow requirement. Response: Both ponds have been redesigned such that diffuse flow is provided for the design storm and bypass flows are directed to a riprap apron and channel section that will provide nonerosive velocities through the buffer. 4. Drainage area 2 appears to encompass both Lots 3 and 4. The total impervious area allotted to these two lots per the deed restriction form is 133, 634 sf(98, 010 sf+35,624 sf). However,Section IV.10 of the application indicates that the offsite lot allocation is 128, 844 sf. Please explain the difference in these two numbers. Response: Drainage area 2 does encompass both Lots 3 and 4 as well as a small portion of Lot 1. The driveway entrances are part of Lot 1, but will be treated by the East Pond (Drainage area 2). The deed restrictions and application have been revised based upon changes to the driveway configurations and to ensure consistency between them. 5. In Section IV.10 of the application, the sum of the impervious areas for drainage area 2 does not appear to add up to the total presented. Please confirm the impervious areas are presented correctly. Response: Section IV.10 of the application has been revised as per previous comment and now adds up to the total impervious presented. flECEIVE JUL 28 2014 BY: S:\6523\0001\10-Comm\13-Comm with Regulatory Bodies\2014-07-16 RESPONSE LETTER to C Nelson NCDENR.doc v MCKIM&CREED Ms. Christine Nelson July 28, 2014 Page 3 6. Please provide calculations supporting the information presented in the wet detention basin supplements including the minimum required storage volume and the drawdown time of the wet detention basin. Also please note that the minimum required storage volume for the East Pond is slightly lower than expected given the provided drainage area conditions. Response: The calculations requested above were included in Attachment rro) \r`o'L, \3 of the original submittal however have been revised to take into r +' account the revisions included in this submittal. All calculations are "�' `' enclosed herein for your reference. 7. Per Figure 10-2b of the BMP Manual, the depth used in the average depth calculation for Option 2 is considered to be the distance between the bottom of the vegetated shelf and the bottom of the wet detention basin. The depth used in the average depth calculations for this project appears to be the distance between the permanent pool and the bottom of the wet detention basin. Please confirm that the correct depth is used in the equation and that the rounded average depth used for the SA/DA ratio is presented in the supplement. Response: The average depth calculations for DA#2 - East Pond have been revised to follow Figure 10-2b of the BMP Manual. Please see attached calculations. DA#1 - West Pond is no longer being permitted as a wet detention pond. 8. The drainage area map indicates that the drainage area will start at the property boundary along the right-of-way. However, the northern entrance appears to propose curbing all the way to the road (which would collect runoff within the right-of-way) and is a slightly different shape than the proposed drainage area. Please confirm that the northern entrance road is properly portrayed. Response: The northern entrance road has been revised to show curb & gutter ending at the property line, similar to the southern entrance.

This. northern driveway has also been revised to show only a right in turn movement per NCDOT comments. 9. Please provide additional spot elevations, such as the elevation of the top of the curb, along the edges of the drainage areas to support the identified drainage areas. Response: Additional spot elevations are now shown on sheet 8, CG-10.1. 10. Please confirm the catch basin location for CB-6 along Outparcel g3 on plan sheet CG-101. The arrow points to a pipe instead of a catch basin. Response: The catch basin label for CB-6 has been updated and additional label for CB-6A has been added. The arrows now point to the structures instead of the pipe. 11. Please clarify the following on the wet detention basin cross section detail on plan sheet CG502. a. The temporary pool elevation for West Pond is listed as 11.7 ft on the plans but 11.6 ft in the supplement. Response: The temporary pool elevation is now 9.9 ft due to revised average depth calculations and revised pond limits outside of vegetated buffer. The plans and supplements have been revised to reflect the new temporary pool elevation. b. Please identify the distance being described by "N". Is this the average depth? The depth at which sediment needs to be removed? Response: The distance "N"is the depth at which sediment needs to be removed. The detail has been revised to state as such. r E IVE I) JUL 2 8 2014 f3Y.

The seasonal high water table is listed as "P" but is not identified in the table. Response: The seasonal high water table designation of"P"has been added to the table with associated elevations. 12. Please clarify the address presented in Section III.1.b of the application. It appears that two street addresses have been provided. Response: The address has been revised. 13. For any portion of the project that will be sold in the future, please be sure to provide drainage easements along the collection system and access easements, if necessary, to provide access to the wet detention basins for inspections and maintenance. Response: Access, utility and drainage easements are provided to all parcels. These easements are also required and have been preliminarily approved by Brunswick County Planning and Zoning. 14. If the project is within 5 statute miles of a public airport, the Division cannot require the use of a BMP with a permanent pool of water. A copy of the permit will be forwarded to the airport's director who may elect to adjudicate the permit if the applicant has chosen to use a BMP with a permanent pool of water.

Moore' Cc: Scott, Georgette Subject: RE: Long Beach Crossing - request for additional info Rick, First off, I would like to thank you for your patience. I sent pictures of the proposed site plan and the pond details to Raleigh in order to obtain additional clarification regarding ponds in and near the vegetated buffer and how to apply the rules. They were able to provide answers to the following questions, which have been confirmed with Georgette: What parts of the pond can be located within the buffer? The guidance I have seen either says the top of the embankment or the temporary pool elevation. Based on the language in the 2H .1000 rules, it is agreed that only up to the top of the embankment of the wet pond should be in the buffer. Including any more of the pond area within the buffer does not appear to be consistent with the following sections of the rule: Definition in.1002: "Vegetative Buffer" means an area of natural or established vegetation directly adjacent to surface waters through which stormwater runoff flows in a diffuse manner to protect surface waters from degradation due to development activities.The width of the buffer is measured horizontally from the normal pool elevation of impounded structures,from the bank of each side of streams or rivers,and from the mean high water line of tidal waters, perpendicular to the shoreline. .1005(e)Vegetative Buffer. Developments permitted under Paragraph(a)shall contain a 50 foot wide vegetative buffer,as defined in Rule.1002(22)of this Section,for new development activities and a 30 foot wide vegetative buffer for redevelopment activities.The width of a buffer is measured horizontally from the normal pool elevation of impounded structures,from the bank of each side of streams or rivers,and from the mean high waterline of tidal waters, perpendicular to the shoreline.The vegetative buffer may be cleared or graded, but must be planted with and maintained in grass or any other vegetative or plant material. Furthermore,stormwater control best management practices(BMPs), or stormwater control structures,with the exception of wet detention ponds, may be located within this vegetative buffer. The Division may,on a case-by-case basis,grant a minor variance from the vegetative buffer requirements of this section pursuant to the procedures set out in 15A NCAC 02B.0233(9)(b).Vegetative buffers and filters required by this section and any other buffers or filters required by State water quality or coastal management rules or local government requirements may be met concurrently and may contain, in whole or in part, coastal, isolated,or 404 jurisdictional wetlands that are located landward of the normal waterline. How do we apply the diffuse flow guidance to pipe discharges? They are saying the plans meet option 5 since the discharge rate for the design storm is less than 0.5 cfs. But option 5 only mentions swales... The consensus was that providing a dissipater pad directly adjacent to the stream (even if the flow is small), does not meet the diffuse flow requirements. The clarification from Raleigh went on further to suggest that the proposed site plan might not have enough space for a properly sited wet pond and diffuse flow measure. Suggested alternatives include opportunities to provide permeable pavement at an elevation that is far enough above SHWT to work or a closed sand filter,with is another space-saving option. I do apologize for the confusion regarding ponds and buffers. Each site is a bit different and having the plans really does help us provide more accurate guidance on how to meet the rules. Please let me know if I can be of further assistance. Christine i Nelson, Christine From: Nelson, Christine Sent: Wednesday, July 16, 2014 9:51 AM To: 'Richard (Rick)A. Moore' Subject: RE: Long Beach Crossing - request for additional info Rick, I have sent up an e-mail asking for clarification on the conflicting guidance I have seen regarding what parts of the pond can be within the buffer. I'm not sure what the first part of your second paragraph is trying to say. The provided SW calculations in Attachment 3 of the narrative only have 6 pages: a set of calculations for pond stage-storage, average depth, required surface area, drawdown flow, and energy dissipaters for each pond. Perhaps not all of the calculations were included in the attachment? In reading the guidance, it appears that there are two parts that need to be looked at—the peak discharge from the BMP and the flows in excess of the discharge rate up to the 10-year storm event. I have also asked for clarification on how the options work as they all seem to focus on vegetated swales and don't really address a stormwater outfall/pipe discharge. (I don't see a swale proposed after the rip rap apron, did you intend on providing a swale?) However, it is pretty clear that the flow in excess of the design storm does need to be non-erosive. The outfall protection table on sheet CG502 indicates the velocity will be pretty high. Did you have calculations demonstrating the rip rap apron reduces the flow to a non-erosive level? Sorry I'm not much help at the moment, but I will hopefully hear something back this morning.

Your comment#3 - I know there was a comment (#6) about not having the supporting information for determining minimum storage volumes and drawdowns-those calculations/data were included in the SW narrative/calculation package, Attachment 3 - not directly with the supplements. Maybe that is my fault. Regardless, the orifice drawdown calcs in this section show a discharge rate of 0.07 CFS for both ponds using Ho and still indicate much less than 0.5 CFS using H as the driving head. Does this not qualify us for exemption from the diffuse flow requirements per the attached? Specifically option 5 on page 2? These are discharge swales from our ponds.

The "clarification" that I believe you were referencing in this comment was not for a different project, it was for this project specifically. And the way I read Linda's guidance (this was before you were involved) in the attached e-mail -the portion she wrote on 3/3/2014 at 3:11pm - it states that we measure the 30' buffer from the temporary pool surface, not the top of the embankment. I'm not trying to split hairs but just as I indicated to Linda in the attached e-mail, even a few feet makes a big difference. Assuming that we measure from the temporary pool,there is still a small section that will need to be regraded to meet the requirement, but certainly much less than if we have to measure the 30' from the top of the embankment. I hope to hear back from you fairly quickly on this clarification with the submittal deadline next Monday. Thanks for any help you can provide.

An existing sewer easement runs through the property parallel to Jump and Run Creek. The east side of the property is zoned as CO-CLD and the west side is zoned CO- R-6000. The zoning line will serve as a dividing line between the proposed development to the east and undisturbed area to the west. The property fronts NC Hwy 133 which is currently under construction, while the remaining perimeter is bounded by residential development. The existing topography is mildly sloping. Stormwater runoff in undeveloped area drains as sheet flow to Jump and Run Creek; runoff from the former Lowe's site drains through a stormwater collection system directly into Jump and Run Creek. There are wetlands present both within the parcel boundary and within the stormwater project boundary. Keller Environmental is currently coordinating a total of 0.06 acres of wetland impacts and a proposed 89 linear foot stream impact to Jump and Run Creek through the U.S. Army Corps of Engineers. Based on the USDA National Resources Conservation Service Soil Survey, the underlying soils within the project area are predominantly Muckalee loam (Mk), Torhunta mucky fine sandy loam (To), Murville mucky fine sand (Mu),Mandarin (Ma), and Leon fine sand(Lo). According to the latest surface water classifications published by NCDENR, Jump and Run Creek is classified as an SC; Sw. Proposed Improvements The Long Beach Crossing project proposes to install a 35,502-square foot retail anchor building, along with an additional 12,000-square foot attached retail space, 10,800-square foot permissible stand-alone building area, three (3) outparcels and the remainder of the parcel (Lot #2) will remain undisturbed. Associated parking lots, driveways, and loading areas will also be included in the proposed development. The runoff from the project site will be conveyed through a piped system that drains to(one of two onsite wet detention ponds,or through a proposed level spreader. The ponds will treat the first 1.5-inch s of runoff and will ultimately and Run Creek. a V....4%.#r C .�-ec.So 5 .4'4( discharge into Jump � S�+' � . The West(Pond ,`rind Contech Stormfilter system has been designed to treat runoff from Drainage Area (DA) #1 (see DA map) which consists of proposed BUA on Lot #1 and future runoff from Lot #5. The East Pond has been designed to treat future runoff from DA #2 (see DA map) which consists of the main entry drive, proposed outparcels #3 and #4 and the future right in/right out. Proposed Lot #2 is not associated with proposed development and will remain undisturbed. Both ponds provide diffuse flow for design storm discharge as well as Page 2 bypass systems that utilize riprap pads to provide non-erosive velocities through the buffer. Because of the proximity to the bypass flow dissipator pads, the level spreaders show a concrete block wall (DA#1 - West Pond) or a combination modular and concrete block wall (DA#2 - East Pond) around them to prevent overflow at the end of the level spreaders. The Contech Filtration, Wet Detention Pond and Level Spreader Supplements contain much of the design information however additional supporting calculations can be found in Attachment 3 of this document. This information includes required volume calculations, stage-storage data, drawdown calculations, riprap pad/outlet channel calculations, etc. DA #3 consists of the grocery store's roof and the northeast corner of the paved driveway area (see DA map). This area consists of 1.17 acres of proposed BUA that will be provided with equal or better protection than is currently provided to the 1.18 of existing BUA within the DA#1 limits (see DA map). The existing 1.18 acres of BUA in DA#1 and the existing 1.71 acres of BUA in DA#2 both flow through a stormwater collection system and discharge directly into Jump and Run Creek. This system outlets into the 24" CMP with a broken headwall shown on the Existing Conditions plan sheet, sheet 3, CX-101. The 21" CMP beside the 24" pipe is a former discharge point for offsite drainage that flowed through the existing drainage easement (to be abandoned). This offsite system was redirected and now flows in a storm pipe down the right of way of NC 133 to Jump and Run Creek. This redirection was designed and constructed as part of the ongoing NCDOT project R-3324. With the proposed site development, 1.71 acres of impervious surface in DA#2 that is currently discharging directly into Jump and Run Creek will be treated in a wet detention pond (East Pond); 1.17 acres of the 1.18 acres of existing impervious surface in DA#1, although not being treated in a new BMP meeting all regulatory criteria, will be provided "equal or better protection" by passing through a level spreader and vegetated filter strip prior to entering Jump and Run Creek. The total disturbed area for this project is 12.6 acres. Clearing and grading efforts will be required for the majority of this project site. Erosion protection will consist of a construction entrance, silt fence with adequately spaced stone outlets,inlet protection and sediment basins. il, h + 2 8 (Jq u JL BY:.-._- Page 3 ATTACHMENTS 1 - USGS MAP SOUTHPORT(NC)QUADRANGLE NORTH CAROLINA (CAROLINA (BOLIVIA) mlftopo TOPOGRAPHIC SERIES BEACH) 078°04'01.97"W FUNSTON1 078°01'39.37"W 033°58'24.19"N �- ._ ` ,�- y• + - _ 033 58 24.19 N _ . d 4 _ ., '" — ry '` Y « ale `� l f / ( 1-: .. _ .... ‘\ / i `-.).7 i ).41'. / • so ...▪ �.w .._ fir» __ jaw• 2 I . �N. \ti _�� - r (7.: 1 /) - t • U• Aii , Gem �t�rA.

Visconsi is. currently under contract with Coastal Carolina Commercial Development, LLC to purchase and re- develop this property. We are pleased to submit the following project to you for US Army Corps of Engineers (COE) 404 approval using Nationwide Permits (NWP) 18 and 39. We are requesting NWP 18 to impact 2,599 SF (0.06 Acres) of riparian wetland areas and NWP 39 for 89 LF of stream impacts. Existing Conditions- The existing commercial property is located at 4891 Long Beach Road in Southport, NC. It is '/4-mile south of the intersection of NC-211 (Southport Supply Road) and NC-133 (Long Beach Road). The property is forested primarily with mixed pine/hardwood. There are 2 perennial streams. Jump and Run Creek flows from the western part of the property and confluences with the northern tributary. The flow proceeds southwest to NC133. There are also existing structures remaining from the Lowes Home Improvement prior to its move up the street to NC211 intersection. A sewer line parallels the northern tributary and Jump and Run Creek to the east. NCDOT is currently constructing the NC133 (Long Beach Road; R-3324)) bypass road at the front of the parcel. The former acreage of the tract when delineated is 31.423- acres. The new acreage is 27.46-acres due to the new bypass road A large (6.783 acre) wetland exists on the western end of the property. It's mostly comprised of a bottomland hardwood forest. However, venus fly traps, pitcher plants and sundews were present along the northern edge of the western wetland area. The general land use in the vicinity of the project consists of residential subdivisions, shopping centers, mini-storage and forested areas. Long Beach Crossing 404 Permit Submittal June 24, 2014 Page 2 of 2 Proposed Wetland Impacts- There are two (2) small wetland areas in the northwest corner of the parcel. Please refer to Sheet E3 and the jurisdictional survey. They are located on the sewer line easement adjacent to the UT to Jump and Run Creek. We are proposing removing the 2,599 SF (0.06 Acres) areas. This will allow for the retail shopping center and its associated structures to be properly placed in the parcel's buildable area. Utilizing NWP 18 will allow for the proposed level spreader to be placed in contour with the existing sewer easement and topography while maintaining diffuse flow to the perennial stream. Proposed Stream Impacts- At the rear of the proposed retail shopping center and near the two aforementioned wetland areas, there is a proposed stream impact. Please refer to Sheet E3 and the jurisdictional survey. We are proposing culverting the 89-linear feet reach. This stream location has an abrupt bend and is directly adjacent to the property line. Culverting it will allow for the drainageway to stay on the site and allow for the fire lane and loading areas to be properly graded. Utilizing NWP 39 will allow for the proposed culvert to be placed in accordance with the regional conditions; i.e., below stream grade. Stream and Wetland Protection- The large (6.783 acre) western wetland and surrounding upland areas will be preserved to protect Jump & Run Creek and downstream waterways. Approximately 2,700 linear feet of perennial streams and their associated riparian buffers will also be protected. We have attached several items to the attached PCN to assist your review of the project.

'Preliminary Soil Evaluations for Stormwater Best Management Practices Suitability,Proposed Retail Development,Long Beach Road SE, Southport,North Carolina,S&ME Project No. 1061-13-434,dated July 2, 2013,prepared for Visconsi Companies,prepared by S&ME. 1 Geotechnical Engineering Report S&ME Project No. 1061-13-343A Stormwater BMPs, Long Beach Crossing, Southport, NC May 5, 2014 1.4 Site Description The site is at the approximate location as shown on Figure 1. The site is comprised of a parcel designated 22100057 on the Brunswick County GIS website. The site totals 27.67 acres in size and is bounded to the east by a proposed NCDOT roadway and to the southwest by a perennial stream. An existing sanitary sewer easement is located near the southwestern and western site boundaries. The majority of the site is undeveloped and wooded. The northeastern portion of the site was occupied by a commercial building and concrete pavements at the time of our field work in January 2014. 2 FIELD EXPLORATION PROGRAM 2.1 Soil Test Borings S&ME's subcontract driller advanced soil test borings in or near the locations of the proposed western and eastern stormwater BMP between January 7 and 15, 2014. These borings are designated B-6, B-7, B-17, B-21, B-22, B-23, and B-24. S&ME personnel located the borings in the field by using a hand-held GPS unit and measuring distances from existing site features. The approximate boring locations are shown in Figures 2A and 2B. The soil test borings were drilled using wash boring drilling procedures with a CME-45 drill rig mounted on a tow-behind trailer. Within the borings, samples of subsurface soils were generally taken at 2.5-foot intervals within the upper 10 feet, and at 5-foot intervals thereafter using a split-spoon sampler. Standard penetration testing(SPT)was performed in conjunction with split-spoon sampling in general accordance with ASTM D 1586. At completion of the drilling operations temporary slotted PVC standpipe piezometers were installed in Boring B-7. The remaining soil test borings were left open. S&ME's subcontract driller also advanced auger probe borings without sampling at the locations designated as SW-6 through SW-13 on Figure 2 to depths of 8 to 15 feet below the ground surface. Temporary slotted PVC standpipe piezometers were installed in these boreholes. On January 17, 2014, groundwater depths were measured in the piezometers and the open boreholes. The open boreholes were then backfilled. Groundwater levels were also measured in the piezometers on February 6 and April 3, 2014. Representative portions of the split-spoon samples were returned to our laboratory for visual- manual classification in general accordance with the Unified Soil Classification System. Boring logs containing soil descriptions, SPT N-values, and drilling observations are included with this report. S&ME personnel measured the ground surface elevations at some of the boring locations (SW- 6 through SW-13, B-6, B-7, B-17, and B-22 using a rod and level on January 17, 2014. The rim elevation of the sanitary sewer manhole near the southern property corner was provided by McKim& Creed as 10.02 feet, and was used a benchmark for our measurements. 2 Geotechnical Engineering Report S&ME Project No. 1061-13-343A Stormwater BMPs, Long Beach Crossing, Southport, NC May 5, 2014 2.2 Soil Testing for Stormwater Facilities During the initial preliminary soil evaluations performed in June 2013, our personnel observed that the perennial stream present along the southwestern property border appears to have been deepened at some time in the past. This was evidenced by soil piles observed along both sides of the stream, steep stream bank slopes, and sloughing and erosion of the stream bank. This presents the potential for additional, man-induced drainage of the soils adjacent to the stream. Our soil testing for the proposed stormwater management facilities included evaluation of the soils for the evidence of a relic seasonal high water table associated with pre-stream modification soil conditions and measurement of hydraulic conductivity rates. S&ME personnel advanced hand auger borings to depths ranging from approximately 3 to 8 feet below the existing ground surface at the test locations. The hand auger borings, designated SW-1 through SW-4 and SW-6 through SW-13, were advanced at the approximate locations shown on Figures 2A and 2B. (SW-5 was advanced in the central portion of the site in a proposed pavement area, which is not planned to be pervious pavement at this time.) Borings SW-1 through SW-5 were advanced on June 26, 2013, as part of the preliminary geotechnical services for the proposed stormwater management features2 for this project. Ground surface elevations for these boring were estimated from the Grading and Drainage Plan. Borings SW-6 through SW-13 were advanced on January 6, 2014. The soils encountered in the hand auger borings were evaluated by a North Carolina Licensed Soil Scientist for evidence of seasonal high water table influence. This evaluation involved looking at the actual moisture content in the soil and observing the matrix and mottle colors. Depending on the soil texture,the soil color will indicate processes that are driven by past water table fluctuations such as iron reduction and oxidation(i.e. redoxymorphic features) and organic matter staining. The change in the shape and distinctiveness of the redoxymorphic features can be an indicator of a relic seasonal high water table that has been affected by artificial drainage. Relic water table conditions are typified by sharp, distinct boundaries between the oxidized and reduced areas of the soil profile, whereas current water table conditions are typified by a diffuse boundary between the oxidizing area and the reduced area. Soil science descriptions and elevations of the relic seasonal high water table from the hand auger borings are given in the hand auger boring logs in the Appendix. S&ME personnel also performed the in-situ soil hydraulic conductivity testing by using a compact constant head permeameter at the test locations. Hand auger borings were advanced with a 2-inch diameter bucket to depths of approximately 24 inches above the relic seasonal high water table. The water dissipating unit was lowered to the bottom of the hole, and water was dispensed from the permeameter. The water was allowed to move through the unit until z Preliminary Soil Evaluations for Stormwater Best Management Practices Suitability,Proposed Retail Development,Long Beach Road SE, Southport,North Carolina,S&ME Project No. 1061-13-434,dated July 2, 2013,prepared for Visconsi Companies,prepared by S&ME. 3 Geotechnical Engineering Report S&ME Project No. 1061-13-343A Stormwater BMPs, Long Beach Crossing, Southport, NC May 5, 2014 steady-state flow was achieved, and then flow rates were recorded. The last three measurements were averaged to achieve the most representative value to express the saturated hydraulic conductivity. The depth interval of the tests corresponded to a layer of material approximately 6 inches thick at the selected testing depths. As previously discussed, S&ME's subcontract driller also drilled auger probes and installed temporary standpipe piezometers at or near the hand auger boring locations in the proposed stormwater wet pond areas (SW-6 through SW-13). The groundwater elevations were measured in the temporary piezometers on January 17, February 6, and April 3, 2014. 3 LABORATORY TESTING S&ME performed organic content tests, moisture content tests, grain-size tests, and Atterberg limits tests on representative samples obtained from the borings. These tests were performed to confirm visual soil classifications and estimate the engineering properties of the soils tested. Testing was performed in general accordance with applicable ASTM standards. Test results are attached in the Appendix. 4 SUBSURFACE CONDITIONS 4.1 Soil Test Borings The borings generally encountered approximately 12 inches of topsoil and rootmat at the ground surface. Below these surficial materials,two basic soil strata were encountered within the maximum exploration termination depth of 20 feet. The strata are briefly described in the following table. Table 1 —Generalized Subsurface Strata I Average air Stratum Depth(Feet) Average Relative Densityor N g From To Consistency and Description (bpf) 1 1 g Very Loose Sand 8 (SP, SP-SM, SM, SC) 2 9 20 Soft Clay 3 (CL) Notes: avg = average N = Standard Penetration Test blow count bpf = Blows per foot Variable amounts of organics (wood, roots, or other plant matter) were encountered in the Stratum 1 Sand in numerous borings. Moderate amounts (more than approximately 3 percent per ASTM D 2974) were observed and/or measured by laboratory testing in B-23 and B-24. 4 Geotechnical Engineering Report S&ME Project No. 1061-13-343A Stormwater BMPs, Long Beach Crossing, Southport, NC May 5, 2014 Water levels were measured in the soil test boring boreholes and piezometers on January 17, 2014. The water levels varied from depths of approximately 3 to 8 feet below the existing ground surface,with an average depth of 6 feet. Groundwater levels have been measured or inferred in the explorations at the times and under the conditions stated on the logs in this report. Changes in the groundwater conditions and depths may occur due to seasonal variations in rainfall, evaporation, construction activity, surface water runoff, and other site specific factors. 4.2 Soil Evaluation for Stormwater Facilities The hand auger borings encountered A-Horizon soils (i.e. organic topsoil)to depths varying between 3 and 20 inches below the existing ground surface. SW-8, SW-13, and SW-14 encountered fill at the ground surface to depths of 6 to 15 inches below the ground surface. This fill is likely soil excavated during past deepening of the nearby stream, during construction of the nearby sanitary sewer line, or during construction on the adjacent site to the southeast. The underling soils encountered in the hand auger borings visually-manually classified as sand, loamy sand, sandy loam, and clay in general accordance with the U.S. Department of Agriculture classification system. S&ME personnel observed evidence of relic seasonal high water table conditions in soils adjacent/near the perennial stream, specifically, distinct boundaries/edges of the redoxymorphic features. The relic seasonal high water table elevations at the test locations are given on the hand auger boring logs in the Appendix. Please note that the evaluation of the soils for evidence of relic high water table conditions is based on secondary evidence and not on direct groundwater level measurements. The soils encountered in the hand auger borings and soil test borings in and near the proposed stormwater quality/detention areas are shown on the subsurface profiles given in Figures 3 through 5. The groundwater elevations measured in the temporary piezometers on January 17, and April 3, 2014, are also shown. The water elevations in the stream measured on Janauary17, 2014, are shown, as well. 5 CONCLUSIONS AND RECOMMENDATIONS As mentioned earlier, it appears that the existing stream adjacent to the proposed stormwater quality/detention areas has been excavated and deepened in the past. Spoil piles of soil were observed at the site near the stream and on the adjacent property on the other side of the stream. Also, we measured the stream channel to be approximately 7 to 10 feet lower than the adjacent ground surface. We also observed that the stream banks were nearly vertical with areas of sloughing and erosion present which is not typical for low-order, low-velocity coastal plain streams. Lastly, soil redoxymorphic features observed also indicate an alteration in subsurface water table conditions. Therefore, we have concluded that the stream channel adjacent to the site has been modified. 5 Geotechnical Engineering Report S&ME Project No. 1061-13-343A Stormwater BMPs, Long Beach Crossing, Southport, NC May 5, 2014 Based on the water elevations measured in the piezometers,the relative permeabilities of the different soil strata, the soil science evaluation of the soils, and our observations of the stream bank and channel for side seepage, we conclude that: • The soils still retain indications of the relic seasonal high water table, which occurred before natural cutting of the stream channel at its present location and additional excavation of the stream channel at some point in the past. • Using Lateral Effect software version 2.7 obtained from N.C. State University,the natural cutting and modification of the stream channel have resulted in a horizontal lateral effect ranging from approximately 175 feet to over 200 feet from the stream, within which groundwater levels have been lowered. We anticipate that the greatest lowering is occurring within approximately 50 feet of the modified stream channel. • Water infiltrating the upper sands will seasonally be trapped by the underlying clays and perched within the upper sands, ultimately flowing laterally toward the modified stream channel. • The water table elevations measured on April 3, 2014, were higher than on January 17 and February 6, 2014. • The April 3, 2014, are likely representative of the actual seasonal high water table elevations that occur at the site due to precipitation, evapotranspiration, groundwater flow(including groundwater flow from contributing areas at higher elevations), and stream effects. We assume that the existing modified stream channel will not be filled in, deepened, or otherwise significantly modified during the design life of the proposed stormwater quality/ detention areas to be constructed for this project. Therefore,we recommend that the stormwater BMP's be designed using the elevations and infiltration rates given in the following table. (This table also gives the existing ground surface elevation, relic seasonal high water table elevation estimated from the soil chroma, texture and structure, and measured groundwater elevations on April 3, 2014, for reference only.) 6 Geotechnical Engineering Report S&ME Project No. 1061-13-343A Stormwater BMPs, Long Beach Crossing, Southport, NC May 5,2014 Table 2-Proposed Western Stormwater Wet Pond Existing Relic Seasonal Recommended Ground- Hydraulic Test Location Ground High Water Design Seasonal water Conductivity Surface Table Elevation High Water Table Elevation Rate Elevation (feet) Elevation on 4/3/14 (in/hr) (feet) (feet) (feet) SW-3 14.2(1) 12.1 10.0 NM NM SW-4 14.2(2) 12.9 10.4 NM 0.48 SW-6 13.1 8.7 8.0 7.8 16.95 SW-7 13.6 12.4 10.0 9.5 4.66 SW-8 14.5 13.6 13.0 12.6 3.43 SW-9 13.0 11.7 8.5 8.1 3.38 SW-10 13.4 11.2 10.5 10.4 2.28 SW-11 13.4 11.7 12.0 11.9 0.57 Notes: (1) = Not measured.

The recommended design seasonal high water table elevations are also shown on the subsurface profiles given in Figures 3 through 5. The stormwater management facilities in the proposed stormwater quality/detention areas should be designed in accordance with the North Carolina Best Management Practice (BMP) Manual. Minimum separation depths from the seasonal high water table, minimum infiltration rates, and other requirements for various BMP's are given in that document. 7 Geotechnical Engineering Report S&ME Project No. 1061-13-343A Stormwater BMPs, Long Beach Crossinq, Southport, NC May 5, 2014 Based on the locations of the tests relative to the proposed pond locations and anticipated excavation depths, we recommend that the western stormwater wet pond be designed for a seasonal high water table at elevation 10.0 feet and the eastern stormwater wet pond be designed for a seasonal high water table at elevation 8.5 feet. 6 LIMITATIONS OF GEOTECHNICAL REPORT This report has been prepared in accordance with generally accepted geotechnical engineering practice for specific application to this project. Any wetland, environmental, or contaminant assessment efforts are beyond the scope of this geotechnical exploration; and therefore,those issues are not addressed in this report. The conclusions and recommendations contained in this report are based upon applicable standards of our practice in this geographic area at the time this report was prepared. No other warranty, expressed or implied,is made. Conclusions and recommendations submitted in this report are based, in part, upon the data obtained from the geotechnical exploration. The nature and extent of variations between and away from the borings, soundings, and/or test pits may not become evident until construction. If variations appear evident, then it will be necessary to re-evaluate the recommendations of this report. In the event that any changes in the grades, nature, design, or location of the proposed project are planned,the recommendations contained in this report should be reviewed and modified or confirmed in writing. S&ME should be provided the opportunity to review the final plans and specifications in order that earthwork, foundation, and other recommendations are properly interpreted and implemented. The recommendations in this report are contingent on S&ME's observation and monitoring of earthwork and foundation construction activities. 8 samE APPENDIX S&ME,INC./ 3006 Hall Waters Drive,Suite 100/ Wilmington,NC 28405/p 910,799.9945/ www.smeinc.com $S&ME Important Information About Your Geotechnical Engineering Report Variations in subsurface conditions can be a principal cause of construction delays, cost overruns and claims. The following information is provided to assist you in understanding and managing the risk of these variations. Geotechnical Findings Are Professional Services Are Performed for Specific Projects Opinions Because the scope of each geotechnical Geotechnical engineers cannot specify material exploration is unique, each geotechnical report is properties as other design engineers do. unique. Subsurface conditions are explored and Geotechnical material properties have a far broader recommendations are made for a specific project. range on a given site than any manufactured Subsurface information and recommendations may construction material, and some geotechnical not be adequate for other uses. Changes in a material properties may change over time because proposed structure location, foundation loads, of exposure to air and water, or human activity. grades, schedule, etc. may require additional geotechnical exploration, analyses, and Site exploration identifies subsurface conditions at consultation. The geotechnical engineer should be the time of exploration and only at the points where consulted to determine if additional services are subsurface tests are performed or samples required in response to changes in proposed obtained. Geotechnical engineers review field and construction, location, loads, grades, schedule, etc. laboratory data and then apply their judgment to render professional opinions about site subsurface Geo-Environmental Issues conditions. Their recommendations rely upon these The equipment, techniques, and personnel used to professional opinions. Variations in the vertical and perform a geo-environmental study differ lateral extent of subsurface materials may be significantly from those used for a geotechnical encountered during construction that significantly exploration. Indications of environmental impact construction schedules, methods and contamination may be encountered incidental to material volumes. While higher levels of subsurface performance of a geotechnical exploration but go exploration can mitigate the risk of encountering unrecognized. Determination of the presence, type unanticipated subsurface conditions, no level of or extent of environmental contamination is beyond subsurface exploration can eliminate this risk. the scope of a geotechnical exploration. Scope of Geotechnical Services Geotechnical Recommendations Are Not Professional geotechnical engineering judgment is Final required to develop a geotechnical exploration scope to obtain information necessary to support Recommendations are developed based on the design and construction. A number of unique geotechnical engineer's understanding of the project factors are considered in developing the proposed construction and professional opinion of scope of geotechnical services, such as the site subsurface conditions. Observations and tests exploration objective; the location, type, size and must be performed during construction to confirm weight of the proposed structure; proposed site subsurface conditions exposed by construction grades and improvements; the construction excavations are consistent with those assumed in schedule and sequence; and the site geology. development of recommendations. It is advisable to retain the geotechnical engineer that performed the Geotechnical engineers apply their experience with exploration and developed the geotechnical construction methods, subsurface conditions and recommendations to conduct tests and exploration methods to develop the exploration observations during construction. This may reduce scope. The scope of each exploration is unique the risk that variations in subsurface conditions will based on available project and site information. not be addressed as recommended in the Incomplete project information or constraints on the geotechnical report. scope of exploration increases the risk of variations in subsurface conditions not being identified and addressed in the geotechnical report.

PROPOSED IMPROVEMENTS ATTACHEMENT 1 —USCS MAP ATTACHMENT 2— BRUNSWICK COUNTY SCS SOILS MAPS ATTACHMENT 3 — SITE PLAN Page 1 DESIGN NARRATIVE Existing Site • The proposed site of the Visconsi. Companies Ltd. 27.5-acre project primarily consists of woodland, however a metal storage building and concrete pad which once housed a Lowe's Home Improvements store is also partially located on the site. An existing sewer easement runs through the property parallel to Jump and Run Creek. The east side of the property is zoned as CO-CLD and the west side is zoned CO-R-6000. The zoning line will serve as a dividing line between the proposed development to the east and proposed conservation area to the west. The property fronts NC Hwy 1.33 which is currently under construction, while the remaining perimeter is bounded by residential development. The existing topography is mildly sloping and stormwater runoff drains as sheet flow to Jump and Run Creek. There are wetlands present within the parcel boundary, however, there are no wetlands within the stormwater project boundary. Based on the USDA National Resources Conservation Service Soil Survey, the underlying soils within the project area are predominantly Muckalee loam (Mk), Torhunta mucky fine sandy loam(To),Murville mucky fine sand (Mu), Mandarin (Ma), and Leon fine sand (Lo). According to the latest surface water classifications published by NCDENR, Jump and Run Creek is classified as an SC;Sw. Proposed Improvements The Visconsi Companies LTD - Southport, NC project proposes to install a 35,502-square foot retail anchor building, along with an additional 9,600-square foot attached retail space, 10,800- square foot permissible stand-alone building area and four(4)outlots. Associated parking lots, driveways, and loading areas will also be included in the proposed development. The runoff from the project site will be conveyed through a piped system that drains to two (2) onsite wet detention ponds. The ponds will treat the first 1.5-inches of runoff and will ultimately discharge into Jump and Run Creek. The total disturbed area for this project is estimated to be twelve (12) acres. Clearing and grading efforts will be required for the majority of this project site. Erosion protection will consist of a construction entrance, silt fence with adequately spaced stone outlets, inlet protection and sediment basins. Page 2 ATTACHEMENTS 1 -- USGS MAP •1 , • �!

EXISTING SITE IL PROPOSED IMPROVEMENTS ATTACHEMENT 1 —USGS MAP ATTACHMENT 2—BRUNSWICK COUNTY SCS SOILS MAPS ATTACHMENT 3 — SITE PLAN Page DESIGN NARRATIVE Existing Site The proposed site of the Visconsi Companies Ltd. 27.5-acre project primarily consists of woodland, however a metal storage building and concrete pad which once housed a Lowe's Home Improvements store is also partially located on the site. An existing sewer easement runs through the property parallel to Jump and Run. Creek. The east side of the property is zoned as CO-CLD and the west side is zoned CO-R-6000. The zoning line will serve as a dividing line between the proposed development to the east and proposed conservation area to the west. The property fronts NC Hwy 133 which is currently under construction, while the remaining perimeter is bounded by residential development. The existing topography is mildly sloping and stormwater runoff drains as sheet flow to Jump and Run Creek. There are wetlands present within the parcel boundary, however, there are no wetlands within the storniwater project boundary. Based on the USDA National Resources Conservation Service Soil Survey, the underlying soils within the project area are predominantly Muckalee loam (Mk), Torhunta mucky fine sandy loam(To), Murville mucky fine sand (Mu), Mandarin (Ma), and Leon fine sand (Lo). According to the latest surface water classifications published by NCL)ENR, Jump and Run Creek is classified as an SC; Sw. Proposed Improvements The Visconsi Companies LTD -Southport, NC project proposes to install a 35,502-square foot retail anchor building, along with an additional 9,600-square foot attached retail space, 10,800- square foot permissible stand-alone building area and four(4) outlets. Associated parking lots, driveways, and loading areas will also be included in the proposed. development. The runoff from the project site will be conveyed through a piped system that drains to two (2) onsite wet detention ponds. The ponds will treat the first 1.5-inches of runoff and will ultimately discharge into Jump and Run Creek. The total disturbed area for this project is estimated to be twelve (1.2) acres. Clearing and. grading efforts will be required for the majority of this project site. Erosion protection will consist of a construction entrance, silt fence with. adequately spaced stone outlets, inlet protection and sediment basins.

Moore' Cc: Kathryn Espinoza; Weaver, Cameron Subject: RE: Visconsi Shopping Center question Rick, If you think about redevelopment on a more global level, I think this will answer your question. When designing a site that is strictly a redevelopment exclusion project, then you just show that the redeveloped BUA, in its new configuration, is not increasing and that the treatment is equal or better to the existing condition. If the BUA then increases beyond what is existing, you can still get the redevelopment exclusion for the amount of existing BUA that is not within one of those pond drainage areas as long as it is equal to or less than the existing BUA and demonstrates equal or better treatment. For this combo type permit, the amount of existing redeveloped BUA can be rearranged the same way as a pure redevelopment exclusion,you just have to demonstrate it is equal or less BUA and equal or better treatment. Without seeing what the existing treatment is, I cannot say whether the level spreader will be considered equal or better, but you can certainly provide something to justify it though it might be a tougher sell since you are moving it closer to the surface waters. By the way, have you gotten permission to pipe that stream to avoid the BUA in the buffer issues? I hope this makes sense. Please let me know if you have more questions!

From: Richard (Rick) A. Moore [mailto:RAMooreftmckimcreed.com] Sent: Friday, May 16, 2014 12:14 PM To: Nelson, Christine Cc: Kathryn Espinoza Subject: Visconsi Shopping Center question Christine- This is in reference to the shopping center in Southport that we had a scoping meeting on about a month ago. We have a submittal set for May 29. Question for you as we tighten up everything for the submittal. We discussed in the scoping meeting that our existing impervious had to be included in the calcs for our treatment volume if the area flowed through the BMP. We have been looking at and discussing various grading arrangements to utilize slotted drains to bypass this existing BUA around the BMP. As we looked at our options, It brought up a question -do we have to exclude the existing BUA from the BMP or can we "swap" it with some of the proposed BUA for the site? I think the pdf will explain better what I'm asking than I can here in text. The scenario in the attached pdf shows 1.2 acres of existing BUA in red (I excluded the existing BUA on outparcel 3 because it is in a different drainage area going to the pond in the SE corner). The blue area is approximately 1.1 acres. The question is whether we can take the credit for the 1.2 acres of existing BUA and use it for the proposed BUA shown in blue. We would provide a level spreader and filter strip at the outlet for the runoff from the blue to provide equal or better treatment. And the red existing BUA would be treated in our proposed wet pond in the SW corner. 1 Please let me know if this is acceptable. If it isn't, we will have to design our wet pond with retaining walls underwater. I try to avoid this at all costs for many reasons... Thanks, Rick Richard (Rick) A.

EXISTING SITE IL PROPOSED IMPROVEMENTS ATTACHEMENT I —USGS MAP ATTACHMENT 2— BRUNSWICK COUNTY SCS SOILS MAPS ATTACHMENT 3 — SITE PLAN Page 1 DESIGN NARRATIVE Existing Site The proposed site of the Visconsi Companies Ltd. 27.5-acre project primarily consists of woodland, however a metal storage building and concrete pad which once housed a Lowe's Home Improvements store is also partially located on the site. An existing sewer easement runs through the property parallel to Jump and Run Creek. The east side of the property is zoned as CO-CLD and the west side is zoned CO-R-6000. The zoning line will serve as a dividing line between the proposed development to the east and proposed conservation area to the west. The property fronts NC Hwy 1.33 which is currently under construction, while the remaining perimeter is bounded by residential development. The existing topography is mildly sloping and stormwater runoff drains as sheet flow to Jump and Run Creek. There are wetlands present within the parcel boundary, however, there are no wetlands within the stormwater project boundary. Based on the USDA National Resources Conservation Service Soil Survey, the underlying soils within the project area are predominantly Muckalee loam (Mk), Torhunta mucky fine sandy loam(To), Mu.rville mucky fine sand (Mu), Mandarin (Ma), and Leon fine sand (Le). According to the latest surface water classifications published by NCDENR, Jump and Run Creek is classified as an SC; Sw. Proposed Improvements The Visconsi Companies LTD — Southport, NC project proposes to install a 35,502-square foot retail anchor building, along with an additional 9,600-square foot attached retail space, 10,800- square foot permissible stand-alone building area and four(4) outlots. Associated parking lots, driveways, and loading areas will also be included in the proposed development. The runoff from the project site will be conveyed through a piped system that drains to two (2) onsite wet detention ponds. The ponds will treat the first 1.5-inches of runoff and will ultimately discharge into Jump and Run Creek. The total disturbed area for this project is estimated to be twelve (12) acres. Clearing and. grading efforts will be required for the majority of this project site. Erosion protection will consist of a construction. entrance, silt fence with adequately spaced stone outlets, inlet protection and sediment basins.

Effective immediately, the Division of Energy, Mineral and Land Resources and the Division of Water Resources will consider Options 1-4 as meeting the diffuse flow provisions of the BOTH the stormwater rules AND the various riparian buffer rules. Option 5 will be allowed for meeting the diffuse flow provisions of the stormwater rules but is not currently allowed for meeting the diffuse flow provisions of the buffer rules The water quality design storm intensity for diffuse flow is the one inch/hour storm for stormwater conveyed directly from the drainage area. If a diffuse flow device receives flow from an upslope BMP, then it should be designed based on the peak discharge from the BMP during the water quality design storm depth. Flows in excess of the discharg re ate from either the drainage area or the BMP should not be directed to the diffuse flow device. Instead, excess flows should be discharged through the buffer provided that the flows are non-erosive for the 10-year storm. Please note that any new stormwater bypasses from a level spreader through a protected riparian buffer require a buffer authorization from the Division of Water Resources or the local buffer protection authority. Please see the options listed in the table below. Any questions regarding the use of these diffuse flow options can be directed to Annette Lucas at (919) 807-6381. March 7,2014 Options for Meeting Diffuse Flow Provisions of the Page 2 of 3 Stormwater and Riparian Buffer Protection Programs Option Explanation 1 Design a Level Spreader-Vegetated Filter Strip (LS-VFS) in accordance with Chapter 8 of the BMP Manual. Per the BMP Manual, the LS-VFS may be designed to handle the one inch/hour storm intensity and larger storms may be discharged non-erosively. Also per the BMP Manual, alternate designs that create uniform shallow flow across a vegetated filter strip in an equivalent or better manner will be approved. 2 Provide a BMP that removes a minimum of 30% of TN removal outside of the vegetated or riparian buffer to treat the design storm before it is discharged through the buffer. 3 (For lower SHWT and soils with good infiltration rates) Design the vegetated conveyance to infiltrate the design storm. 4 (For high SHWT and/or soils with poor infiltration rates) Design the vegetated conveyance as a wetland swale with an appropriately designed outlet system. 5 Swales that discharge less than 0.5 cfs during the design storm shall be allowed to discharge through a stormwater buffer outside of SA waters without any further requirements. This option is NOT currently allowed if the buffer is protected by a state riparian buffer rule (Neuse,Tar-Pamlico,Jordan, Randleman, Catawba, and Goose Creek). Explanation Diffuse flow is not defined in the 2H .1000 rules; however, the following explanation of diffuse flow is provided in each of the Riparian Buffer Protection rules found in 15A NCAC 2B .0233 (Neuse River Basin), .0259 (Tar-Pamlico River Basin), .0243 (Catawba Mainstem), .0250 (Randleman Lake), .0605 (Goose Creek), .0267 (Jordan Lake). (5) DIFFUSE FLOW REQUIREMENT. Diffuse flow of runoff shall be maintained in the riparian buffer by dispersing concentrated flow and reestablishing vegetation. (a) Concentrated runoff from new ditches or manmade conveyances shall be converted to diffuse flow before the runoff enters the Zone 2 of the riparian buffer. (b) Periodic corrective action to restore diffuse flow shall be taken if necessary to impede the formation of erosion gullies. (6) TABLE OF USES. The following chart sets out the uses and their designation under this Rule as exempt, allowable, allowable with mitigation, or prohibited. The requirements for each category are given in Item (7) of this Rule. March 7,2014 Options for Meeting Diffuse Flow Provisions of the Page 3 of 3 Stormwater and Riparian Buffer Protection Programs Exempt Allowable Allowable Prohibited with Mitigation Drainage ditches, roadside ditches and stormwater outfalls through riparian buffers: • Existing drainage ditches, roadside ditches,and X stormwater outfalls provided that they are managed to minimize the sediment, nutrients and other pollution that convey to waterbodies • New drainage ditches, roadside ditches and X stormwater outfalls provided that a stormwater management facility is installed to control nitrogen and attenuate flow before the conveyance discharges through the riparian buffer X • New drainage ditches, roadside ditches and stormwater outfalls that do not provide control for nitrogen before discharging through the riparian buffer X • Excavation of the streambed in order to bring it to the same elevation as the invert of a ditch In the past, the state has interpreted the diffuse flow language in the buffer rules to mean that designers have two primary options to provide diffuse flow: • Provide a Level Spreader-Vegetated Filter Strip (LS-VFS) in accordance with Chapter 8 of the BMP Manual. Per the BMP Manual, the LS-VFS may be designed to handle the one inch/hour storm and larger storms may be discharged non-erosively. (Option 1 above) • Provide a BMP that removes a minimum of 30% of TN removal outside of the vegetated or riparian buffer to treat the design storm before it is discharged through the buffer. (Option 2 above) The above table provides three additional options. Options 3 and 4 are intended to provide relatively low-cost approaches to providing treatment in the swale prior to discharge through a buffer. Option 5 provides an exemption to the diffuse flow provision in the stormwater rules for very low flows. As stated previously, the current wording in the riparian buffer rules does not allow the Division of Water Resources to provide an exemption to the diffuse flow requirements, even for low flows. ?Th -4 iv\ ,i'c'p Nelson, Christine From: Lewis,Linda [linda.lewis@ncdenr.gov] Sent: Thursday, March 06, 2014 3:42 PM To: Richard (Rick)A. Moore Subject: RE: Proposed Southport development project You cannot reduce the width of the buffer, but the 2008 rules do allow for a "variance" process for persons who wish to undertake uses designated as prohibited,which would be the location of BUA in the buffer or perhaps the location of a wet pond within the buffer. For prohibited uses within Zone 1 of the buffer,you will need a major variance. Unfortunately, all of the 30 foot redevelopment buffer in the coastal counties is Zone 1. Your variance request would require approval through the Environmental Management Commission. Please refer to NCAC 028.0233 (9) (a), (b) and (c) (the "RED" book)for information on the variance process and the required justification. From: Richard (Rick) A.

Moore Cc: Kathryn Espinoza Subject: RE: Proposed Southport development project That question I can answer it would be measured from the temporary pool elevation. There is a lot of grassed slope of the pond that can be in the buffer, i.e.,the grading that's allowed, but none of the water surface itself. From: Richard (Rick) A. Moore f mailto:RAMoore@mckimcreed.coml Sent: Thursday, March 06, 2014 2:26 PM To: Lewis,Linda Cc: Kathryn Espinoza Subject: RE: Proposed Southport development project Hi Linda- Thank you very much for the info below. According to the Brunswick County Tax Records, the buildings were built in 1984 (see attached -the buildings are listed at the bottom with the year built).Therefore no stormwater permit was required. And it sounds like we would qualify for redevelopment as described below and therefore the 30' surface water buffer. The stream is a blue line and is shown on the USGS quad map. So we are planning to buffer that. And of course we are looking at a wet detention pond so that won't be allowed in the buffer area as discussed below-and I won't ask why... I will ask though, because of course we are tight on space -does the 30' buffer go from top of bank to normal pool?Or to 1 ` top of temporary storage volume, oc.? | know it seems trivial but when we are already tight on space, E/ can make o difference. Thank you for the very helpful information below vve will move forward with the design and look forward toscheduling ascnping meeting soon!

Moore Cc: Kathryn Espinoza Subject: RE: Proposed Southport development project Richard 8Kathryn: I have not been able to locate an existing permit for that old Lowe's you mention. Do you know when that structure was built? If the site has an existing stormwater permit (or was required to get one and did not), then the project cannot be excluded from permitting. You would have to pick up and treat the runoff from all the BUA, not just what is added over and above the existing BU& Assuming there is no existing permit, then even though the proposed total BUA might exceed the existing BUA, you can still qualify for u redevelopment exclusion for a portion of the site, and just treat the additional BUA. If any of the runoff from the existing BUA is within the drainage area of the new BIVIP, then it must also be accounted for in the design of the new 8MP. Because the BUA is increasing, you would necessarily apply for a high density permit for the new BIVIP, bu1hvvuu|dhavearedeve|nprnentcomponen1to "exc|ude" threxistin8BUA, as |ongasthetreatmentproposedforthe existing BUA was equal or better than before. If there is no existing stormwater permit, or if one was not required, and you meet the redevelopment requirements as described above, the required surface water buffer will be3O' If the stream is shown as a blue line on the USGS quad, then it's a surface water. If you need any clarification, please contact Chad Coburn with the Division of Water Resources to request a stream determination. Wetlands are waters of the state but they are not considered surface waters,therefore, they are not subject tnbuffering. The surface water buffer is defined in the rules as an area of natural or established vegetation directly adjacent to surface waters through which stormwater runoff flows in a diffuse manner to protect surface waters from degradation due to development activities. The width of the buffer is measured perpendicular to and horizontally from the normal pool elevation of impounded structures, the top of bank of each side of streams and rivers, and the MHW line of tidal waters. Since the definition of the buffer is a "vegetated area", it may be graded, but no built-upon area can be located within the buffer, except for water-dependent uses such as a bulkhead and boat ramp.

Let me do the research and get back to you later. Linda From: Richard (Rick) A.

Or did it simply get stuck in your mailbox like happens to all of us from time to time? I attached the original Google Earth exhibit but also included a new exhibit that shows our site (with the proposed NCDOT improvements included) in much more detail. This new exhibit is for graphical illustration only-the site plan scale provided by the client didn't match up exactly with the aerial and it doesn't reflect a buffer from Jump and Run Creek. We understand a buffer is required and will provide that based upon your feedback on our questions below. I appreciate any input you can provide. Thanks, Rick From: Richard (Rick) A. Moore Sent: Tuesday, February 25, 2014 11:32 AM To: Linda Lewis (linda.lewis@ncdenr.gov) Cc: Kathryn Espinoza Subject: Proposed Southport development project Linda- We are currently working on a site just west of Southport near the intersection of 211 and 133. The site is an old Lowe's Home Improvements store site but has not been used in that capacity for a long time. It is now being used primarily as a warehouse/storage facility for a trucking company. The current plan is to redevelop this site into a shopping center. The client wants to go through the express permitting process so if this e-mail gets too complex and it is best to go ahead and sit down for our express scoping meeting, let me know and we will submit the request package. The project is adjacent to Jump and Run Creek(SC; sw). We have not done the calculations yet but I'm certain we will exceed the current BUA on site with the proposed development.Therefore we are proposing to treat all runoff in new BMPs meeting today's rules. First question is related to Table 2-2 of the BMP manual. It call for a "high density setback/buffer" of 30'for redevelopment and 50'for new development in SC waters (State S/W heading). Although we do not qualify for a redevelopment permit with our increase in BUA, this is technically a redevelopment site,therefore do we follow the 30' setback? I assume this setback is measured from the water's edge? If the channel is determined to be an RPW does the setback still apply? It shows as a blue line stream on the quad but still wanted to ask the question. We may have a consultant go out and take a look at it to make a determination. 3 One other question, I did not find anything in the manual that describes what is and is not allowed in this setback. Is it strictly BUA that isn't allowed in the setback? Are BMP's allowed in the setback? Again, if better to hash this out in a scoping meeting I'm glad to set one up so we can keep moving forward with this project. Thanks for your help- Rick Richard (Rick) A.
