Project Overview: Regional
The proposed Covington Ridge development is located on a 38.2 acre parcel in the city of Trinity in
Randolph County. The property is located along Unity Street approximately 0.3 miles north of NC 62.
The proposed development will include townhouse units and a commercial outparcel. This submittal is
only for Phase 1A. A modification will be submitted in the future for later phases.
Existing Site Description:
The site is primarily grassed with a pocket of wooded area on the eastern side. A ridge runs north to
south roughly through the middle of the parcel. The western portion is flatter and slopes toward Unity
Street at ±2%. The eastern portion is steeper and flows toward a stream near the middle of the eastern
parcel line. Slopes in this portion are more variable and are generally between 4-8%. The project
encompasses the entire 38.2 acre site. The parcel property pin number is 7805798852. The soil on site
consists of Mecklenburg clay loam (MeB2) and Mecklenburg loam (MaC). The site does not lie within a
100- year floodplain or the 500-year floodplain (DFIRM Panel 3710679700J). Currently, the runoff from
the site runs in four main directions; to the west through an NCDOT cross pipe and into a drainage
system, to the east into the existing stream, to the south into NCDOT line drainage, and to the
northeast. The property lies within the Uwharrie River (13-2-(0.5)) watershed in the Yadkin Pee -Dee
River Basin.
Proposed Project Description:
The proposed project consists of a new townhome subdivision, including roads, sidewalks, and
associated utilities. Access to the site will be provided via two (2) entrances on Unity Street and an
additional entrance through a shared access through the parcel in the southeast. A total of 235
townhouse units will be constructed, with 28 units constructed as part of Phase SA.
Sewer Construction:
The project will use gravity piping and manholes with separate gravity services and cleanouts for each
unit. Phase SA will consist of approximately 453 LF of 8" DIP under pavement and 626 LF of 8" SDR-21
PVC under grassed areas and pavement. The system will cross under Unity Street and connect to the
existing Stone Gables subdivision gravity sewer system that eventually drains to the Hamby Creek
WWTP, permit number NC0024112. The pipe under Unity Street will be encased in steel for the extent
of the Unity Street R/W per NCDOT standards.
Stability... Value... Experience... let our experience make yours better!

7. Upon completion of construction and prior to operation of these permitted facilities, the completed
Engineering Certification form with checklist attached to this permit shall be submitted with the
required supporting documents to the address provided on the form. Any wastewater flow made
tributary to the wastewater collection system extension prior to completion of this Engineer's
Certification shall be considered a violation of the permit and shall subject the Permittee to
appropriate enforcement actions. A complete certification is one where the form is fully executed and
the supporting documents are provided as applicable. Supporting documentation shall include the
following:
a. One copy of the project construction record drawings (plan & profile views of sewer lines & force
mains) of the wastewater collection system extension. Final record drawings should be clear on
the plans or on digital media (CD or DVD disk) and are defined as the design drawings that are
marked up or annotated with after construction information and show required buffers,
separation distances, material changes, etc.
b. One copy ofthe supporting applicable design calculations including pipe and pump sizing, velocity,
pump cycle times, and level control settings, pump station buoyancy, wet well storage, surge
protection, detention time in the wet well, and force main, ability to flush low points in force
mains with a pump cycle, and downstream sewer capacity analysis. If a portable power source or
pump is dedicated to multiple stations, an evaluation of all the pump stations' storage capacities
and the rotation schedule of the portable power source or pump, include travel timeframes, shall
be provided.
c. Changes to the project that do not result in non-compliance with this permit, regulations, or the
Minimum Design Criteria should be clearly identified on the record drawings, on the certification
in the space provided, or in written summary form.
Prior to Certification (Final or Partial): Permit modifications are required for any changes resulting
in non-compliance with this permit (including but not limited to pipe length changes of 10% or
greater, increased flow, pump station design capacity design increases of 5% or greater, and
increases in the number/type of connections), regulations, or the Minimum Design Criteria.
Requested modifications or variances to the Minimum Design Criteria will be reviewed on a case -by -
case basis and each on its own merit. Please note that variances to the Minimum Design Criteria
should be requested and approved during the permitting process prior to construction. After -
construction requests are discouraged by the Division and may not be approved, thus requiring
replacement or repair prior to certification & activation. [15A NCAC 02T .0116]

8. Gravity sewers installed greater than ten percent below the minimum required slope per the Division's
Gravity Sewer Minimum Design Criteria shall not be acceptable and shall not be certified until
corrected. If there is an unforeseen obstacle in the field where all viable solutions have been
examined, a slope variance can be requested from the Division with firm supporting documentation.
This shall be done through a permit modification with fee. Such variance requests will be evaluated
on a case -by -case basis. Resolution of such request shall be evident prior to completing and submitting
the construction certification. [ 15A NCAC 02T.0105(n)]
9. A copy of the individual permit and construction record drawings shall be maintained on file by the
Permittee for the life of the wastewater collection facilities. [15A NCAC 02T .0116]

Division's Gravity Sewer Design Criteria adopted February 12, 1996 as applicable; the Division's
Minimum Design Criteria for the Fast -Track Permitting of Pump Station and Force Mains adopted June
1, 2000 as applicable; and other supporting materials may subject the Permittee to an enforcement
action by the Division, in accordance with North Carolina General Statutes §143-215.6A through §143-
215.6C, construction of additional or replacement wastewater collection facilities, and/or referral of
the North Carolina -licensed Professional Engineer to the licensing board. [15A NCAC 02T .0108(b-c)]
11. In the event that the wastewater collection facilities fail to perform satisfactorily, including the
creation of nuisance conditions, the Permittee shall take immediate corrective action, including those
as may be required by this Division, such as the construction of additional or replacement facilities.
[15A NCAC 02T .0110; 15A NCAC 02T .0108(b)]
12. The issuance of this permit shall not exempt the Permittee from complying with any and all statutes,
rules, regulations, or ordinances that may be imposed by the Division any other Federal, State, or Local
