From: Lewis,Linda [mailto:linda.lewis@ncdenr.gov] Sent: Thursday, April 30, 2015 6:08 PM To: charlie Subject: Dunkin Donuts SW8 150312 Charlie I've issued the modified permit for the Villas at Murrayville, SW8 060717. In addition to the review comments below, I will need to wait for a copy of the new recorded deed restriction to be submitted before continuing with the permitting of Dunkin Donuts. Please address the following: 1. The BUA assigned to the outparcel under SW8 060717 is now 21955 sf. I've adjusted the allocated BUA that you reported on the offsite supplement from 21,806 to 21,955. Do you want to add an extra 149 square feet to the 5591 sf of future BUA you are currently showing on the application? If so, please submit just that revised page of the application. 2. Please add the property line to the plans with bearings and distances. I think the property line might be partially obscured by the limits of disturbance. Since I'm not permitting the erosion control aspect, you could remove the limits of disturbance. 3. Please add building dimensions, concrete area dimensions and the rest of the parking area dimensions to the plans. You should continue the drive aisle dimension across the parking space to the curb (face or back — please specify). 4. The legend box appears to be a bit heavy on the erosion control symbols. Please add the stormwater items including the cross -hatching symbol and the concrete symbol. Please submit two copies of the revised plans, the updated application page and a copy of the recorded deed restriction by May 30, 2015. Thanks, Linda Linda Lewis, E.I.

This system (check one) CI does X does not incorporate a vegetated filter at the outlet. This system (check ogre) 13 does X does not incorporate pretreatment other than a forebay. . Maintenance activities shall be performed as follows: After every significant runoff producing rainfall event and at least monthly: a. Inspect the wet detention system for sediment accumulation, erosion, trash accumulation, vegetated cover, and general condition. b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within 2 to 5 days as designed. 2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative cover to maintain a maximum height of six inches, and remove trash as needed. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain proper functioning. 4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of in an appropriate manner and shall not be handled in a manner that will adversely impact water quality (i.e. stockpiling near a wet detention basin or stream, etc.). The measuring device used to determine the sediment elevation shall be such that it will give an accurate depth reading and not readily penetrate into accumulated sediments. When the permanent pool depth reads 5.62 feel in the main pond, the sediment shall be removed. When the permanent pool depth reads 2.25 feet in the forebay, the sediment shall be removed.

College Road (Parcel #314909-17-7141) in Wilmington, North Carolina. The site drains to an existing wet detention basin that was constructed in 2006. This submittal is for a permit Modification. Under Pen -nit ##SW8 060717 issued on October 26, 2006 the site was permitted for 331,818 sf of BUA. 'With this modification the BUA is proposed to be 338,953 sf. The pond as originally designed is capable of handling this increase in BUA as shown in the calculations. There are wetlands located in the southwestern corner of the site that have been field verified by the USACOE. SOILS The soils for this project consist of Seagate (Hydrologic Soil Group AID), Woodington (Hydrologic Soil Group BID), Baymeade (Hydrologic Soil Group A), Pantego (Hydrologic Soil Group BID) and Johnston (Hydrologic Soil Group D)series soils. The Seagate soils consist of somewhat poorly drained, moderately permeable soils, the Woodington series soils consist of poorly drained, moderately rapidly permeable soils, the Baymeade series soils consist of well drained, moderately rapidly permeable soils, the Pantego series soils consist of very poorly drained, moderately permeable soils and the Johnston series soils consist very poorly drained, moderately rapidly permeable soils. STORM DRAINAGE DESIGN The primary stormwater measures for this project will be an existing wet detention basin. The stormwater will be conveyed via overland sheet flow and a closed conduit system to the existing wet detention basin that is be designed and built to treat the first l" of rainfall and to control the post development peak discharge for the 2, 10 & 25-year storm events so as not to exceed the pre -development peak runoff discharge rate to meet NCDENR & New Hanover County Stormwater Regulations.

When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the actual impervious %and permanent pool depth. Linear interpolation should be employed to determine the correct value for non- standard table entries. 2, In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide 90% TSS removal. The NCDENR BMP manual provides design tables for both 85%TSS removal and 90% TSS removal. 11. REQUIRED ITEMS CHECKLIST The following checklist outlines design requirements per the Stormwater Best Management Practices Manual (N.C. Department of Environment, Health and Natural Resources, February 1999) and Administrative Code Section: 15 A NCAC 2H .1008.

If a requirement has not been met, attach ,justification. Appl I itials a. The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet). b. The forebay volume is approximately equal to 201/o of the total basin volume. i� c. The temporary pool controls runoff from the design storm event. d. The temporary pool draws down in 2 to 5 days. e. If required, a 30-foot vegetative filter is provided at the outlet (include non -erosive flow calculations). f. The basin length to width ratio is greater than 3:1. 7A g. The basin side slopes above the permanent pool are no steeper than 3:1. h. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail). i. Vegetative cover above the permanent pool elevation is specified. j. A trash rack or similar device is provided for both the overflow and orifice. k. A recorded drainage easement is provided for each basin including access to nearest right- of-way. I. if the basin is used for sediment and erosion control during construction, clean out of the basin is specified to be performed prior to use as a wet detention basin m. A mechanism is specified which will drain the basin for maintenance or an emergency. *A pump shall be provided to drain the basin for maintenance or an emergency. I11. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if one is provided_ This system (check one) ❑ does X does not incorporate a vegetated filter at the outlet. This system (check one) ❑ does X does not incorporate pretreatment other than a forebay. Maintenance activities shall be performed as follows: After every significant runoff producing rainfall event and at least monthly: a. Inspect the wet detention system for sediment accumulation, erosion, trash accumulation, vegetated cover, and general condition. b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within 2 to 5 days as designed. 2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative cover to maintain a maximum height of six inches, and remove trash as needed. 3. inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain proper functioning. 4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of in an appropriate manner and shall not be handled in a manner that will adversely impact water quality (i.e. stockpiling near a wet detention basin or stream, etc.). The measuring device used to determine the sediment elevation shall be such that it will give an accurate depth reading and not readily penetrate into accumulated sediments. When the permanent pool depth reads 5.62 feet in the main pond, the sediment shall be removed. When the permanent pool depth reads 2.25 feet in the forebay, the sediment shall be removed.

The Villas at Murrayville New Hanover County Dear Ms. Davenport: The Wilmington Regional Office received a request to transfer and modify the State Stormwater Management Permit for The Villas at Murrayville on January 22, 2015. A preliminary in-depth review of the proposed modified application has determined that the application is not complete. The following information is needed to continue the stormwater review: Supporting Information requirements applicable to all projects: 02H.1003(g)(4) — Provide topographic maps of the project area showing original and proposed contours and drainage patterns. a. The plans were revised to reflect the "as -built" layout but no grading information for those revised areas has been provided. The previously approved grading plan will still apply to the unchanged parts of the project, but where layout changes have taken place, new grading information must be provided in the form of finished floor elevations, proposed contours and spot elevations. b. Please show the collection system for the roof drainage from Buildings 6 & 7 on the plans. .2. 02H. 1 003(g)(6) — Delineate the existing and the proposed built -upon area including roads, parking areas, buildings, etc. a. Please account for and delineate the playground area located to the south of Building #5. b. Please provide a dimensioned typical building detail for Buildings 3-9. In addition, please provide dimensions for the added maintenance shed, the pool deck, pool building, clubhouse, playground and parking.
