PCN Section B. Project Information & Prior Project History
Item #3a: Existing Condition

There are three primary sewer areas associated with this project serving 1) the Rocky River
Plantation Subdivision, 2) the Planters Row Subdivision and 3) a portion of the Bradford Park
Subdivision The sewer line serving the Planters Row Subdivision, Lines A, the sewer line
serving the Rocky River Plantation Subdivision, Line B, and the sewer line serving a portion of
the Bradford Park Subdivision, Line C will be constructed within a proposed easement, a
mature mixed hardwood forest
Item #3d: Purpose of Proposed Project
Gravity sewer Imes A, B, and C are being constructed to abandon two existing pump stations,
the Quay Farm Pump Station 1, the Highland Ridge Pump Station, and the Bradford Park
Pump Station No 3 currently serving the aforementioned Subdivisions The Highland Ridge
Pump Station, located at the end of Plantation Way, receives flow from the Rocky River
Plantation Subdivision The Quay Farm Pump Station, located at the end of Quay Farm Ct,
receives flow from the Planters Row Subdivision The Bradford Park Pump Station No 3,
located at the end of Moody Ct, receives flow from a portion of the Bradford Park subdivision
The three of these pump stations are to be abandoned The close proximity of the WSACC
Reedy Creek Sewer Interceptor economically promotes the abandonment of the pump stations
Item #3e: Project Description and Equipment
The gravity sewer lines will consist of the following
1 Line A - Approximately 830 LF of 8 -inch gravity sewer line,
2 Line B - Approximately 1,387 LF of 8 -inch gravity sewer line,
3 Line C - Approximately 473 LF of 8 -inch gravity sewer line, and,
4 Various appurtenances for a successful project completion
Typical equipment expected to be used includes, but is not limited to, track hoe excavator, backhoe,
frontend loader, etc The proposed gravity sewer alignments will connect to existing gravity sewer
Imes and will be constructed in several segments Line A will connect to the existing 42 -inch
WSACC Upper Reedy Creek Interceptor At its upper end, Line A will connect to three existing
sewer lines currently discharging into the Quay Farm Pump Station allowing its demolition and
abandonment Line B is a fork off of Line A that will connect to two existing sewer lines currently
discharging to the Highland Ridge Pump Station allowing its demolition and abandonment Line C
will connect the existing 36 -inch portion of the WSACC Upper Reedy Creek Interceptor The
existing wetwell located at the Bradford Park Pump Station No 3 will be converted to a manhole,
beginning the upper end of Line C and allowing for demolition and abandonment of the remainder
of the pump station Sewer line segments connecting to the pumping stations will be plugged and
abandoned
The alignment for the proposed sewer line was determined based on the existing sewer line
locations, existing buildings, existing infrastructure such as overhead power lines, roadways, storm
culverts, and topography

PCN Section C. Proposed Impacts Inventory
Item #2h: Description of Proposed Wetland Impacts
Two bottomland hardwood forest wetland areas will be impacted as part of the project
Temporary impacts to wetlands along the sewer alignment will result from clearing a
temporary construction corridor These temporary impacts will total 0 094 acre and include
forested wetlands The disturbed wetlands will be returned to the original slope and contour
following installation Permanent impacts will be limited to 0 022 acre resulting from a 10' wide
permanent maintenance corridor Total impacts will be limited to 0 116 acre
Item #3i: Description of Proposed Stream Impacts
There will be no permanent stream impacts There will be 3 temporary stream impacts of 15
linear feet each These 3 temporary stream impacts will affect 3 perennial streams Temporary
impacts will total 45 linear feet
PCN Section D. Impact Justification and Mitigation
Item #1a & #1b: Avoidance and Minimization
To minimize impacts to surface water resources during project construction and maintenance,
an approved sediment and erosion control plan will be included in the project's final design
plans, in locations where sewer line installation across streams uses "open cut" method,
crossings will be as close to perpendicular as possible, completed during low flow events, and
monitored at least every three months for maintenance during the first 24 months following
construction and annually thereafter, insecticides and herbicides will not be used within 100
feet of perennial streams or within 50 feet of intermittent streams or within wetlands and
floodplains associated with those streams
Ongoing on -site construction inspections will ensure that construction contractors are following
all approved plans
PCN Section F. Supplementary Information
Item #4a: Sewage Disposal
The project will not generate additional wastewater, but only convey existing flow volumes by
gravity to a different discharge location into existing sewers
Wastewater will be received by the Water and Sewer Authority of Cabarrus County (WSACC)
collection system and ultimately treated at the Rocky River Regional WWTF
The Rocky River Regional Wastewater Treatment Plant (RRRWWTP) is a two stage 26 5 MGD
biological wastewater treatment facility that is owned and operated by the Water and Sewer
Authority of Cabarrus County (WSACC) The facility serves a thriving area north of Charlotte,
including the cities of Concord and Kannapolis, the towns of Harrisburg and Mt Pleasant, and
3

Cabarrus County The staff performs all functions related to the facility including operations
and maintenance, laboratory analysis, and industrial and groundwater monitoring The recently
upgraded plant uses a 95% pure- oxygen activated sludge biological process, and an upgraded
disinfection system that uses sodium hypochlorite for disinfection, eliminating gaseous chlorine
designated as extremely hazardous by EPA and OSHA An upgraded sludge processing system
was completed in 1995 This system included high solids centrifuges for dewatering, high
pressure pumps (originally developed for pumping concrete) for conveying dewatered sludge,
and afterburner /wet electrostatic precipitator scrubbing for the incinerator stack gases (Source

Item #8b: Flood Zone Designation
Portions of the proposed sewer line are located in the FEMA 100 -year floodplain of Reedy
Creek The sewer lines will be installed below grade at the crossing of Reedy Creek
Stockpiling and disposal of material or spoils from excavation of the sewer line will not be
temporarily or permanently stored inside the FEMA 100 -year floodway Stockpiling and
disposal of spoils will take place outside the FEMA 100 -year floodway in designated areas with
approved sediment and erosion control measures
