FORM: FTA 06-21 Page 5 of 5 Narrative for Fast Track Permit NCDOT Project U-6018 Owner - City of Archdale May 20, 2022 CH Engineering is submitting a fast track permit for the City of Archdale including the Fast Track Sewer Extension Application, FTA-06-21 supporting documentation, maps and this narrative. The application is for relocation of existing sewer that will have a reduction in diameter. In 2022, the NCDOT intends to let the job to construct Project U-6018 near the 1-85 and Hwy 62 intersection in Archdale, NC. The project will consist of widening Hwy 62, realigning the Kersey Valley Road intersection with Hwy 62, and adding a roundabout and new roadway off of Weant Road which will attach back to Hwy 62 at the Modlin Grove Rd intersection. The City of Archdale will be cost sharing relocation work of water and sewer facilities throughout the project. Regarding sewer, there are two existing gravity sewers and two forcemain sewers that will require relocations. Both forcemains will be relocated in the Right of Way in the same size and will be considered Permitted by Regulation under 2T .0303(a) 4 D. Similarly, the gravity sewer located on Hwy 62 on the west side of the 1-85 intersection will remain the same size and be placed in the Right of Way and deemed permitted. However, on the east side of 1-85, the sewer along Hwy 61 and turning the corner of Modlin Grove Rd will be downsized and are therefore the subject of this permitting effort. Along the north side of Hwy 62 east of 1-85 is an existing 21-inch gravity sewer. This sewer used to be a regional collector for a large portion of the City of Archdale, but once the Hwy 311 By-pass was constructed, the gravity portion was severed and flow diverted elsewhere. The remaining portion of the 21-inch gravity in the vicinity of the U-6018 project was left in place and currently only services the Citgo gas station and a single residence. Because this sewer will be impacted by proposed storm drainage in the U-6018 project, around 1100 linear feet of the gravity sewer will require relocation. The NCDOT and the City wish to replace the 21-inch with a more appropriately sized 8" gravity sewer since the current and expected future wastewater flows will be very lowand material cost will be minimized. As the 8" gravity line rounds the corner of Modlin Grove Road, the size is increased to 12" to allow for future flows coming from possible future development east of the intersection. The 12" gravity line will end after one segment into an existing manhole with the existing 21-inch sewer since that designates the limits of the NCDOT project. CH Engineering contacted the Winston Salem Regional office about this relocation and due to the difference in pipe diameters from existing, the relocation cannot be deemed permitted by regulation under 2T rules and a Fast Track Sewer System Extension Application is being submitted. The number of homes and small businesses currently served are two in total. Should all existing homes along Hwy 62 currently on septic be added to the system, there would be a total of six connections. Estimating the future in -fill of other homes in vacant lots and at current density would add five homes for a total of eleven future and existing connections. Flow Rates: No new buildings are being added as a result of this project so no new flow will be permitted herein. Because no new flow will be added and the existing system is oversized, the Flow Tracking/Acceptance Form will not be needed. Existing: Using the design flow rates listed in the rules under 15A NCAC 02T.;0114 (b), and assuming an average of four bedrooms in the existing home and eight fixture units at the gas station, the flow for the existing house would be 480 gallons/day and the gas station would yield an estimated 1800 gallons/day. This yields a combined total of 2280 gallons/day of existing flow. The existing receiving collection system predates any permits and therefore has no permit number. The downstream flows eventually wind up at High Point's Eastside WWTP with permit number NC-0024210.
