Adams Subject: Request for Additional Information Stormwater Project No. SW8 041220 Adams Mini Storage Onslow County Dear Mr. & Ms. Adams: The Wilmington Regional Office received a Stormwater Management Permit Application for Adams Mini Storage on December 30, 2004. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: Please revise the vegetated filter detail to conform to the requirement that a filter be a flat area through which the runoff leaving the outlet structure can flow across in a thin sheet. A flow spreader mechanism to distribute the flow across the Width of the filter is required. Please see the attached detail. If the filter cannot be constructed in this manner, please redesign using the 90 TSS criteria. 2. Please label the proposed contour elevations in the pavement. 3. The 1" orifice is too small. A flowrate of .0195 cfs is not greater than the 5 day flowrate of .026 cfs. Please provide a larger orifice. Please revise the orifice size in the outlet structure section detail on Sheet S3 4. Please remove Weeping Love Grass from the seeding specifications for both temporary and permanent cover. 5. Please label the weir elevation from the forebay into the main pond. 6. Please raise the top elevation of the proposed baffles to at least the temporary pool elevation of 95. 7. Please add proposed spot elevations to the paved area in front between the first two buildings and Piney Green Road. 8. The pond section detail A -A on Sheet S3 labels the permanent pool elevation as 96. Please revise this to 94. 9. Please relabel section detail A -A as the "Wet Detention Pond Cross Sectional View".

NARRATIVE PROJECT DESCRIPTION The purpose of this project is to construct twelve (12) commercial buildings to be used as mini storage. The size of the site involved in this project is 4.6658 acres. This site has been graded. At this time Engineer has instructed the owners to start erecting silt fencing to insure that no sediment leaves site. THIS DOES NOT GIVE THE OWNER PERMISSION TO CONTINUE TO GRADE. The site has been evaluated for wetlands and they are none on this site. SITE DESCRIPTION This is an industrial site that has the following characteristics: 1. Sand Loam soil 2. water table at an elevation of approximate 94 as per elevations on this survey. 3. Natural grade slopes to the rear of lot, from east to the west 4. Motts Creek on western end of property. ADJACENT PROPERTY The property all around this site is developed both as commercial and residential. SOIL The soil condition on this site is classified as Onslow Series. PLANNED EROSION AND SEDIMENTATION CONTROL PRACTICES LAND GRADING Some grading has all ready been done to this site. The site will be constructed in two or three phases. All grading will be done at this time, to include the building pads for the buildings which will be constructed at a later date.. CONSTRUCTION ROAD STABILIZATION The driveway will be constructed over the proposed culvert that will be extended as shown on plans, in the center of the lot near the existing driveway. This will serve as the construction entrance also. DUST CONTROL Site will only be exposed for a short time, therefore no dust should be generated. DRAINAGE CALCULATIONS The rational method will be used in all calculations to determine runoff (Q=CIA). The coefficient of runoff that will be used for this developed property will be 0.90 for all runoff calculations. The charts from which intensity will be determined, using ten ( 10) year storm period, will be Wilmington, NC. THE INTENSITY FOR ALL AREAS WILL BE 7.2 INCHES PER HOUR. This is a high density development, and one inch of runoff must be stored on site. The site was designed to include a basin/pond to hold this runoff and at the same time serve as the s3edimentation pond needed for construction. Once construction is completed, sedimentation will be removed from basin/pond. 0 MEMORANDUM from Wayne Ragland p REG#STERED LANDSCAPE ARCHITECT 11)A1�J'1 . {(}cwbeo-5,2004 LICENSED SOIL SCIENTIST Tommy £r Billy Adams COMPANY 11I Wayne Ragland SUBJECT., Parcel #1116-53, 2478 Piney Green Road anessage, Dear Mr Adams In confirmation of our meeting this afternoon, I was able to inspect the above referenced parcel in OnsIOW County today and can confirn] that it does not contain any area that qualifies as wetlands, either under- Section 404 of the Clean Water Act or any other regulatory definition. If' the parcel boundary extends back to the channelized stream at or near the rear property line (the right rear does not but I unsure about the left rear corner), the top of bank of that channel should be located and mapped since it does qualify as waters of the US. Other than activities in, abutting or near that channel, there are no %wetland regulatory constraints on this parcel. In consideration of the sedimentation control issues, a buffer from the channel will be required from any soil disturbing activities proposed but this certainly should not be a problem since your proposed improvements are a long way from that channel. Please advise if there is any questions. I ,_ Wayne Ragland a Licensed Soil Scientist , do hereby certify that I have expertise in the identification of hydric soil conditions as well as the remaining diagnostic criteria for identifying regulated wetlands ; that this assessment was made in confomiance with the "Army Corps of Engineers 1987 Wetland Determination Determination Manual' ; that the above findings are based oil the site conditions in evidence on October 5, 2004 , and ; that all of the above statements are true and correct to the best -of my knowledge and experience.

PROJECT INFORMATION 1. Detail narrative of storm water management This site has been graded. There will be one entrance to this site. The entrance splits to allow for four lanes to join/split inside the entrance. The natural drainage is from east to west. The construction of the buildings and roadways will not interrupt the natural flow of the runoff. Due to change in grade, the runoff will flow into the swales placed inside the roads between the buildings. The area that produces runoff from this site is 4.6658 acres. This runoff will be directed to the sedimentation basin/pond. All drainage from site will enter the forebay of the basin/pond, where it will be channeled to the weir that allows flow into the permanent pool. The runoff from the roof tops and the road beds will be channeled into the swale located in the middle of the each roadway. From the roadway the runoff will flow across the road at the -rear of the buildings and into the forebay. The amount of drainage that will be kept on site is one (111) inch. The flow within the permanent pool was too short so to lengthen the length of flow two (2) baffle walls was added. With the addition of the two (2) added baffle walls the length to width ratio now exceeds the required length:width ratio of (3:1) The runoff from this site will be held in the basin/pond for at least two (2) days but no more than five (5) days. This will be accomplished by using an one (111) inch orifice. The runoff will enter the orifice, then pass on into the twelve (1211) inch pipe where it drains out of the basin/pond. From the twelve (1.2") inch pipe,.the runoff will enter the energy dissipater then the thirty (301) foot vegetated filter before entering Mott Creek.
