Please contact me with questions or comments. 0 =4211 Wr r 1 �r- April 30, 2013 NCDENR - DWQ 585 Waughtown Street Winston- Salem, NC 27107 This letter is intended to clarify our plan for stream stabilization required at 550 Kelway Place in Winston - Salem, NC. Please refer to our submitted plans and PCN in reference to this letter. This project is intended to repair erosion caused by an unnamed tributary of Muddy Creek. The erosion has occurred in a stream bend, causing the stream bank to incise to near vertical, threatening an existing pool, pool deck, and cabana at a single family residence. Our intention is to remove the bend, which appears to have been caused by fallen trees and subsequent entangled debris, and divert the stream flow away from the structures. Compacted fill will be placed to replace lost soil, and then protected using filter fabric and class I rip -rap backed by Geolifts. Work will be limited to periods of dry weather to the greatest extent possible. A temporary sand bag coffer dam with pumps sufficient to pump the normal stream flow around the work site will be provided so that equipment will not be directly in the stream. Please include this letter with our submitted plans and PCN. I am sure that the contractor can keep impacts to the stream minimized while constructing the repairs. We will be providing project testing and oversight throughout the process. I hope that this letter will serve to expedite the approval of our plans. If you have any questions, please call. Thank you for allowing us to be of service. Sincerely, Geoscience & Technology, PA Q t ohn A.

E a Z A t– a Definition n graveled area or pad located at points inhere vehicles enter and leave a construction site. Purpose To provide a buffer area where vehicles can drop their mud and sediment to mvoid transporting it onto public roads, to control erosion from surface runoff, and to help control dust. Conditions Where st herever traffic gill be leaving a construction site and moving directly onto a public road orotherpaved off -site area. Construction plans should limit traffic Practice Applies to property constructed entrances. Design Criteria Aggregate Size —Use 2 -3 inch washed stone. Dimensions of gravel pad - 716ickness: 6 inches minimum !lfdth: 12 -feet minimum or full width at all points of the vehicular entrance and exit area, whichever is greater length: 50 -feet minimum Location—Locate construction entrances and e.cits to limit sediment from :!eating the site andto provide for maximum utility by all constructionvehicles ignue 6.06x): Avoid steep grades, and entrances at curves in public roads. 2 -3" coarse aggregate Im Practice Standards and Specifications Seeding mlxtture Species' Rate (lblacre) Blend of two turf- -type tall fescues (90 + %) and two or more improved Kentucky bluegrass varieties (10 %) 200-250 Seeding dates Best Possible Fall: Aug. 25 - Sept. 15 Aug. 20 - Oct. 25 Winter: -- Feb. 1- Mar. 31 For quality turf, avoid spring seeding.
