III. Certification Statement:
I Amy L. Ratliff certify to the best of my knowledge that the addition of
the volume of wastewater to be permitted in this project has been evaluated along the route to the
receiving wastewater treatment facility and that the flow from this project is not anticipated to
cause any capacity related sanitary sewer overflows or overburden any downstream pump station
en route to the receiving treatment plant under normal circumstances, given the implementation
of the planned improvements identified in the planning assessment where applicable. This
analysis has been performed in accordance with local established policies and procedures using
the best available data. This certification applies to those items listed above in Sections I and II
plus all attached planning assessment addendums for which I am the responsible party.
Signature of this form indicates acceptance of this wastewater flow.

Reference: The Meadows at Oxford Subdivision
Public Gravity Sewer & Lift Station
Mr. Robinson:
This letter is to accompany the submittal package for the Meadows at Oxford public fast track
sewer extension application form FTA 04-16,
LGI Homes -NC, Inc. is proposing a 302-lot single family subdivision comprising approximately
129.95 acres. The site is located within the City of Oxford on NC Highway 96 on Granville County
Parcel ID Nos. 1922-0342-3542, 1922-0450-2921 & 1922-0330-8817. The project will be
constructed in one phase as shown in the attached construction plans.
The 302-lot development consists of 182 three -bedroom single family homes, and 120 four -
bedroom single family homes. Utilizing the 15A NCAC 02T wastewater design flow rate of 120
gallons per day per bedroom for residential dwellings, the total wastewater flow generated by this
project is expected to be 123,120 gallons per day (GPD).
The gravity sewer system consists of 98 proposed manholes (96 — 4' diameter manholes, 1 — 5'
diameter and 1 — 6' diameter), 16,110 feet of 8-inch SDR26 PVC and 1,473 feet of 8-inch CL350
DIP (public). Additionally, the sewer system proposes an aerial crossing within the public section,
with 40' of 16-inch steel casing pipe_
Additionally, the subdivision development proposes a public sewer lift station that will ultimately
be managed/maintained by the City of Oxford. The lift station consists of a single 8' diameter wet
well, with duplex solid handling pumps, pump control system with telemetry, on site backup
generator, and 2,470' of 8-inch C900 PVC force main. The proposed force main will outlet into an
interceptor manhole just south of the wastewater treatment plant_
Please let me know if you have any questions or need any additional information.
