RE: Project Name: Ridgemont Subdivision Section 3 & 4
County: Davie
City: Mocksville
Address: 604 Whitney Road
Submitted by: Kennerly Engineering & Design, Inc.
Ms. Graznak,
Kennerly Engineering & Design, Inc. (KED) submits the following application for your review, comments
and/or approval. Please find attached two (2) copies of the application and calculations for the above
referenced project. KED has been retained as the Design Engineer and Engineer of Record for the
Ridgemont Subdivision Section 3 & 4 located in Mocksville, NC. The project is a continuation of an existing
subdivision that began in the 1970's. Section 3 & 4 are the last sections of the development that have not
been constructed. Section 3 & 4 will consist of single-family homes.
This project will include approximately 4,062 LF of 8" diameter sanitary sewer line. The proposed sanitary
sewer lines will be installed within the right-of-way of the road system except for the outfall connections to
the existing sanitary sewer system owned by the Town of Mocksville. The existing sanitary sewer outfalls
are located within the 100 YR floodplain of Elisha Creek and an. unnamed tributary of Elisha Creek.
The sanitary sewer for this project will be public and will be owned and maintained by the Town of
Mocksville. There will be three (3) sanitary Sewer Outfalls for this section of the subdivision. The outfalls
will include stream crossings, wetlands and floodplain disturbance. KED has contracted an Environmental
Group, NW Geoscience, PC, to permit the stream crossings, wetlands and floodplain disturbances. NW
Geoscience has met on site with the Army Corp of Engineers and delineated the areas of the crossings
and made he determinations with Corp. NW Geoscience has filled for the NW 58 Permits for the sanitary
sewer outfalls and will contact the NC Division of Water Resources to obtain the 401/404 certifications that
will also be needed once the Corp permits are obtained.
An Erosion Control Permit was issued by NCDEQ on September 20, 2021 for the land disturbance activities
for the project. Public Water Supply (PWS) has also issued a permit for Phase 3A of the project and the
remaining portion of the subdivision is under review by PWS currently.
Should you have any questions, please do not hesitate to contact us at 336.775.2118.
Sincerely,
‘0,1--Cri—dor

III. Certification Statement:
I Kenneth Gamble 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 certifies that the receiving collection system or treatment
works has adequate capacity to transport and treat the proposed new wastewater.
