CCIJ�' February 17, 2014 MAR 9, 1 'Lt114 ; NCDENR - DWQ � 585 Waughtown Street Wa r Branch Winston - Salem, NC 27107 120 Fairhaven Court Stream Stabilization Our Project #13.372 This letter is intended to clarify our plan for our stream stabilization project required at 120 Fairhaven Court,m Lewisville, NC. Please refer to our concurrently submitted plans and PCN in reference to this letter This project is intended to repair an eroded stream bank at the referenced address. The erosion has exposed-a 15" vitrified clay sanitary sewer pipe and two pipe points are currently exposed and readily visible in the stream bottom. The eroded area is located in a hairpin turn in the stream alignment. The soil type in the area is highly susceptible to erosion. The pipe is highly susceptible to impact damage from debris in large flows. Our intention is to reconstruct and reinforce the stream bank on both sides of the channel The bend will not be removed, but its centerline radius will be increased. The sanitary` sewer will be relocated per a plan by others, but this does not remove the requirement of repairing the stream since the sewer will still be in the proximity of the realigned bend 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 If you have any questions, please call Sincerely, Carl von IseAlit'g, PE Senior Civil Engineer ) \\\ Ntt ICtAf? �O R, Sao .yy.. 7 SEAL 024697 Ln �NGiNe if /I /O N �5"-� W ATF9QG o -c 20/40276 Office Use Only Corps action ID no DWQ project no Form Version 1 3 Dec 10 2008 Pre - Construction Notification (PCN) Form A.
