Williams, Sr. P.O. Box 28 Currituck, NC 27929 Dear Mr. Williams: NORTH CAROLINA Environmental Quality October 28, 2020 Subject: Stormwater Permit Renewal Stormwater Management Permit SW7070212 Savin Woods Pasquotank County JA A Division of Energy, Mineral, and Land Resources file review has determined that Stormwater Permit SV 7070212 for a stormwater treatment system consisting of a wet detention pond to serve a proposed Savin Woods Subdivision located at the end of Savin Road in Elizabeth City, NC expires on March 1, 2021. This is a reminder that permit renewal applications are due 180 days prior to expiration. We do not have a record of receiving a renewal application. If you wish to keep this permit active, please submit a completed permit renewal application along with a $505.00 fee for permit renewal. If the development has not been constructed and you do not intend to develop it in the future, you may submit a request to have the permit rescinded. Permit application forms for renewal can be found on our website at: littps://deq.iic.gov/about/divisions/energy-niiiieral-land-resources/energy-mineral-lanci- rules/stormwater-program/post-construction. North Carolina General Statutes and the Coastal Stormwater rules require that this property be covered under a stormwater permit if it has been developed. Failure to maintain a permit during and after development subjects the owner to assessment of civil penalties. If you have questions, please feel free to contact me at (252) 948-3923. 1 will be glad to discuss this by phone or meet with you. If you would like, I can e-mail you a copy of the application form. You can request a copy by e-mailing me at roger.thorpe(cDncdenr.gov. Sincerely, Roger K. Thorpe Environmental Engineer North Carolina Department of Environmental Quality 1 Division of Energy -Mineral and Land Resources Washington Regional Office 1043 Washington Square Mall I Washington. North Carolina 27889 252.g4th481 n /z Savin Woods FEB -7-ff 2007 Pasquotank County — Elizabeth City - North Carolina ®�v�'NV!'{�� February6 2007 Savin Woods is a proposed 45 lot residential subdivision located off of Savin Road (SR 1147). The tract to be subdivided contains 19.52 acres, of which 4.40 acres along the eastern edge of the property are 404 wetlands. There is also a FEMA non - encroachment zone in the vicinity of the wetlands. The land is currently vacant and is zoned R-10 (Residential 10,000 sf lots). Development of this subdivision will include construction of approximately 2,185 If of curb and guttered streets with sidewalks, water main, sewer main, related drainage, and one detention pond. The streets will contribute 1.37 acres of impervious surface and the sidewalks will be another 0.34 acres. Coverage on each lot will be limited to 5,500 sf. The maximum coverage for the development is 7.39 acres or 37.86%. According to the Pasquotank County Soils Maps as prepared by USDA, Soil Conservation Service, the soils on this site are predominately Dragston with small areas of Nimno. The soils in the wetlands are Dorovan. An on site soil boring in the detention pond location indicates a sandy loam with modeling. A single soil boring was performed in the detention pond area by Sean C. Robey, PE and Kimberly Hamby on January 23, 2007. The soil boring was conducted with an AMS 2-3/4" diameter 6' long hand mud auger. We encountered wet soil at approximately 36", but the coloration indicated that we were still above the seasonal high water table. The soil was too wet to stay in the auger below 38-40". We feel this is due to the rain on the previous day. Based on this information, we estimate the seasonal high water table to be at about 40". The elevation at the bore location is approximately 7.00'; therefore, the seasonal high water table is estimated to be 3.67'. Normal water surface elevations in the adjacent swamp are approximately 2.00'. Our permanent pool elevation has been set at 3.00'. While Dragston soils have a moderate permeability rate, the high water table makes wet detention the most appropriate stormwater treatment method to use in this area. The pond will discharge to the existing wetlands on the east side of the property. The wetlands are part of a tributary of that drains northwesterly into Knobbs Creek. In addition to meeting state requirements for stormwater treatment, this site will comply with the City of Elizabeth City's Stormwater Ordinance. This ordinance requires that post development runoff not exceed pre development runoff during a 10 year storm event. Rational method analysis indicates a pre development peak runoff of 25.3 cfs. The post development runoff is 38.7 cfs into the pond and a peak pond discharge of 19.67 cfs. 1 Drainage Area 1 contains 14.12 acres that are designed to drain to the Detention Pond. This drainage area includes 59,800 sf (1.37 ac) of roads and 14,997 sf (.34 ac) of sidewalks. It includes all of lots 1-16 and 29-45 and a majority of lots 17-28. The maximum impervious area allowed per lot is 5,500 sf or a total of 247,500 sf (4.29 ac) for this drainage area. The resulting maximum impervious area for this drainage area is 7.39 acres or 52.34%. Runoff from the lots will sheet flow across grassed yards into rear lot line ditches with 3:1 side slopes that will be piped down side lot lines and into the underground pipe system. Front yards will sheet flow across the yard and over the curb and into the curb and gutter system. All of the roadway drainage will be collected in curb and gutter and an underground pipe system that drains to the detention pond. The Detention Pond has been designed for 90% TSS removal. 7 Drainage Area 2 contains approximately 5.40 acres, including the backs of lots ��jj�-��- 4—z? 29-45 and all of the wetlands, which will continue to sheet flow to the existing wetlands. �C'This drainage area will not include any impervious areas. The total disturbed area for development will not exceed 16 acres. This includes the entire tract, except for the area in 404 wetlands and the FEMA non -encroachment zone, plus a portion of the existing street right-of-way as necessary for road construction and utility connection. Limits of disturbance have been shown on the plans. (PERMANENT POOL DETENTION PONDS Hyman & Robey.
