This project consisted of clearing, grading, and installation of infrastructure for a proposed 12,100 SF Daycare Facility. The disturbed area for this project is +/- 3.5 acres and the total amount of impervious area compared with the total project boundary is 24.6%. The erosion control plan identifies the appropriate measures to be implemented for erosion control purposes during construction of the infrastructure associated with this development. SOILS The soils onsite consist of Mandarin Fine Sand and Muckalee Loam series soils. The Mandarin series soils consist of somewhat poorlydrained, flat sandy soils with a Hydrologic soils grouping of C. The Muckalee series soils consists of poorly drained soils on low flood plains with a Hydrologic soils grouping of D. STORM DRAINAGE DESIGN The primary stormwater measure for this project is a proposed Stormwater Wetland located at the front of the property. The stormwater will be conveyed via overland sheet flow and closed conduit system to the proposed stormwater wetland that is designed to treat the first 1.5" of rainfall. The stormwater from this site discharges to the Brunswick River, Classification SC. A SHWT determination was performed by ECS Limited on September 25, 2012 and the SHWT depth at the proposed stormwater wetland was determined to be 14". The ECS Report is attached. r � ' EROSION CONTROL PLAN FOR SPEC DAYCARE - LELAND Area to be disturbed: +/- 3.5 acres This + 3.94 acre site is located at the end of Thomas Garst Lane in the Town of Leland. This project consisted of clearing, grading, and installation of infrastructure for a proposed 12,100 SF Daycare Facility. The disturbed area for this project is +/- 3.5 acres and the total amount of impervious area compared with the total project boundary is 24.6%. The primary stormwater measure for this project is a proposed Stormwater Wetland located at the front of the property. The stormwater will be conveyed via overland sheet flow and closed conduit system to the proposed stormwater wetland that is designed to treat the first 1.5" of rainfall. The stormwater from this site discharges to the Brunswick River, Classification SC. EROSION CONTROL MEASURES: This project will primarily control erosion with the use of a temporary construction entrance, outlet protection at the ends of culverts, temporary silt fence surrounding the site and a sediment basin. The contractor shall install, maintain and remove upon completion the silt fence as necessary to prevent any sediment from leaving the project limits. This will include any temporary stockpile areas if necessary. Contractor shall clean and restore to pre - construction conditions any areas that may inadvertently be damaged due to the failure of the erosion control measures. SCHEDULING OF WORK: Clearing and grubbing shall be scheduled and performed in such a manner that fine grading operations and erosion control practices can follow immediately thereafter. Excavation and embankment operations will be conducted such that cuts and fills will be completed to final grades in a continuous operation. All construction areas not otherwise protected shall be planted with permanent vegetative cover in accordance with the specifications within 15 working days after completion of active construction. MINIMUM AREAS TO BE DISTURBED: Only those areas necessary for timely and proper completion of the project shall be stripped of native vegetation. The angle for graded sloped and fills shall be no greater than the angle which can be retained by vegetative cover or other adequate erosion control devices or structures. Slopes left exposed will, within 21 calendar days of completion of any phase of grading, be planted or otherwise provided with ground cover, devices, or structures sufficient to restrain erosion. All other areas to be stabilized within 15 working days of cease of any phase of activity. PLACEMENT OF SEDIMENT CONTROL DEVICES: All devices (temporary diversions, sediment fences, construction entrances, etc.) for sediment control shall be constructed prior to beginning clearing and grubbing on the site. FINAL COVER: As soon as practicable after finished grades have been established, all operations in connection with establishing final ground cover shall be performed. Any inactive disturbed ground area to remain denuded more than 15 working days shall be temporarily seeded in accordance with the temporary seeding schedule as noted on the plans. All slopes to be stabilized within 21 calendar days. SEQUENCE OF CONSTRUCTION 1. Install temporary construction entrance as shown on erosion & sediment control plan. 2. Install perimeter controls (sediment basin, silt fence, tree protection fencing, etc.) as shown on the erosion & sediment control plan. This step needs to be completed prior to upslope land disturbing activities. 3. Once perimeter controls and sediment trapping measures are installed clear and grub site within limits of disturbance. 4. Upon bringing the site to rough grade, stabilize all areas with temporary vegetation if left undisturbed for 15 working days and all slopes within 21 calendar days. 5. Upon bringing the parking area to subgrade elevations, stabilize the areas by placing stone base as early as possible. 6. For temporary vegetative stabilization of all denuded areas see note referencing the erosion control program and specifications. 7. After construction operations have ended and all disturbed areas have stabilized, mechanical sediment controls shall be removed. Sediment from temporary sediment trapping devices shall be disposed of by spreading on the site or hauling away if not suitable for_fill. All denuded areas are to be permanently stabilized with permanent vegetation. 8. Prior to using the sediment basin as an stormwater wetland it shall be mucked out.

GSP Consulting, PLLC 6626 Gordon Road, Unit C Wilmington, North Carolina 28411 Reference: Report of Infiltration Testing SPEC Leland Leland, Brunswick County, North Carolina ECS Project No. 22.18146 Dear Mr. Pape: ECS Carolinas, LLP (ECS) recently conducted an estimation of the Seasonal High Water Table (SHWT) for the proposed storrnwater best management practice (BMP) area at the proposed SPEC Daycare Facility in Leland, Brunswick County, North Carolina. This letter, with attachments, is the report of our estimation. Field Testing On September 25, 2012, ECS met with Mr. Garry Pape with GSP Consulting in order to locate the requested boring location. ECS then conducted an exploration of the subsurface soil and groundwater conditions at one requested location shown on the attached Boring Location Plan (Figure 1). The purpose of this exploration was to estimate the SHWT of the in place soils for the design of for the proposed stormwater BMP area. ECS explored the subsurface soil and groundwater conditions by advancing one hand auger boring into the existing ground surface at the requested boring location. ECS visually classified the subsurface soils and obtained representative samples of each soil type encountered. ECS recorded the SHWT and groundwater level observed at the time of each hand auger boring. The attached SHWT sheet provides a summary of the subsurface conditions encountered at each hand auger boring location. The groundwater level and the SHWT were estimated at each boring location below the existing grade elevation. Below is a summary of each boring location. Location Water Level SHWT 1 48 inches 14 inches The SHWT may vary within the proposed site due to changes in subsurface conditions and elevation. NC 2fl41 !

E. Governor . Director January 11, 2013 Mr. Ronald Saucier 169 Vision Drive Wilmington, NC 28405 Subject: Request for Additional Information Stormwater Project No. SW8 051143 SPEC - Leland Pender County Dear Mr. Saucier: John E. Skvada, III Secretary The Wilmington Regional Office received and accepted a modified State Stormwater Management Permit Application for SPEC - Leland on November 26,'2012. A preliminary in- depth review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: I� The drainage area and impervious area listed in Section IV.10 of the application is not consistent with the impervious area listed in the wetland supplement. Section IV.10 of the application should have 1 drainage area for the proposed wetland and if any other impervious areas remain outside this drainage area, a second drainage area for the remainder of the property. I/ 2. Please confirm'the total surface area of the wetland and provide additional details in the calculations to support the surface areas of the various wetland zones. The total wetland surface area is considered to include the deep pools, shallow water, and shallow land at the temporary pool elevation, currently set at 13 ft. According to the calculations, the surface area at an elevation of 13 ft is 5,155 ft2; however the supplement reports the wetland surface area as being 4,510 ft2. Once the surface areas have been confirmed, the provided volume is based on the surface area at the permanent pool elevation (currently 12 ft), which according to the calculations is 3,775 ft2, and the surface area at the temporary pool elevation (13 ft). 13 'Please increase the number of plants to be provided in the shallow water area to meet the 50 plants per 200 ft2 area. With the shallow water area being 1883 ft2, a minimum number of 471 plants will be necessary. (1883 ft2 / 200 ft2 * 50 = 471 plants) 4. Please provide additional grading details, including contours and/or spot elevations, in order to support the drainage area delineation. Additionally, please include the roof drain collection lines or include a note on the plans indicating that all roof runoff will be directed to the stormwater collection system. 5. Please confirm the information presented in the cross-section table on sheet C-5. The information presented in this table is not consistent with the information presented in the supplement and calculations. For instance, the Shallow Water Elevation is listed as 11.0 ft on C-5, but is shown as 11.5 in the supplement. Please remember that a change to one number may have a domino effect on other numbers. Please check all plans, calculations and forms to ensure that the numbers are consistent throughout.

Other than that the only thing that could be done is to repave the parking lot to sheet flow the runoff over the retaining wall then through the swales.

The goal is for the site to either meet approved plans and thus meet the requirements for a low density development or modify the site, permit, and approved plans to meet the rules.

From: Garry Pape Sent: Thursday, August 16, 2012 10:02 AM To: 'Nelson, Christine' Cc: Lisa Winchell (lisa@speckids.com) Subject: RE: Notice of Deficiency Christine, Here is the current situation. Right now the stormwater is collected in the parking lot by and inlet that discharges the stormwater through the retaining wall into a swale that directed the water to a dry detention area. The only corrective action I could see to do would be to remove the inlet and storm pipe and to repave the parking lot so that the stormwater sheet flows to the edges of the parking area where it flows over the retaining wall and then through the grassed swales to the dry detention area. I welcome your thoughts on the situation. Thanks. — Garry GarryS Pape, P.E.

Getting it resolved as soon as possible could take a week or a couple months. It would just be helpful if we are all on the same page and timeline. The deadline for the plan of action is August 22, but if you need a little more time let me know. Thanks!
