Cc: Signed: Jefry Bu s,PE SIDBURY LANDING NEW HANOVER COUNTY, NORTH CAROLINA SANITARY SEWER DESIGN NARRATIVE f Prepared for: Bill Clark Homes of Wilmington LLC 101 Autumn Hall Drive, Suite 120 Wilmington, NC 28403 Prepared by: PARAMOUNTE E N G 1 M E 1=. R I N G, 122 Cinema Drive Wilmington, NC 28403 Project#21433.PE I October 2024 I i I I i i i PROJECT NARRATIVE i Bill Clark Homes of Wilmington, LLC is proposing to construct a 219-lot single-family residential subdivision that is located within New Hanover County, directly adjacent to the Pender County Line. The site is approximately 1.5 miles west of the intersection of HWY 17 and Sidbury Road. The project will consist of 219 single family lots that will be developed in multiple phases. The development proposes to construct on-site gravity sewer system to a pump station that will be dedicated to Pluris, LLC upon completion. Along with the pump station the development will construct a 4"force main and 10" force main off-site that will tie into the Pluris,LLC owned 12-inch sanitary force main near Hogans.Trail and Blake Farm Blvd. I The Flow for this development is 39,920 gpd. r The length of sewer main is 9,285 LF of 8" C-900 PVC gravity main. The length of sewer force main is 1,645 LF of 4" C-900 PVC (DR-18), and 9,085 LF of 10" C-900 PVC(DR-18). The project includes high priority sewer collection lines. The 10" force main that runs along Sidbury Rd. and then to the Blake Farms pump station is being sized and installed to accommodate future demand but larger than the present demand. The project will be contributing 5.66% of the overall estimated flow of the 10" force main. Therefore, due to lack of velocity in the line it is considered high priority. It is a requirement for the permittee or it's representative to inspect the high priority lines at least once every six months.

A planning assessment for Kaw Creek PS(see example data above)may be performed to evaluate whether there is significant likelihood that needed improvements or reductions in obligated flows will be in place prior to activating the flows from the proposed sewer extension project. If the system decides to accept the flow based on a planning assessment addendum, it is responsible to manage the flow without capacity related sanitary overflows and must take all steps necessary to complete the project or control the rate of flow to prevent sanitary sewer overflows. The planning assessment may identify a funded project currently in design or construction,or a planned project in the future not yet funded but in a formal plan adopted by the system. The system should carefully weigh the certainty of successful timely project completion for any expansion,flow management diversion or infiltration and inflow elimination projects that are the foundation of a planned solution to capacity tracking and acceptance compliance. For example: Given that: a. The proportion and amount of obligated,not yet tributary flow accounts for 24%and 0.080 MGD of the committed flow in Pump Station Kaw Cree ;and that b. The rate of activation of this obligated, not yet tributary capacity is currently approximately Q,QLMGD per year;and that c.
