Re Pre - Construction Notification, Taggart Creek Outfall and Paw Creek Force Main,
Charlotte Water (formerly Charlotte Mecklenburg Utilities), Charlotte, Mecklenburg
County, North Carolina
To Whom It May Concern,
Please find attached the Pre - Construction Notification (PCN) Application for the above
referenced project Charlotte Water is proposing to replace the existing Taggart Creek Outfall
gravity sewer and Paw Creek force main The proposed replacement pipes will follow the
existing pipes for a portion of the alignment and will be on new location in some portions of the
project The replacement and partial realignment is necessary in order to eliminate flow
restrictions, replace aging infrastructure, and reduce inflow and infiltration issues Additionally,
the project will reduce aerial piping and number of crossings of Taggart Creek, increase system
reliability, and reduce the risk of sanitary sewer overflows (SSOs)
In order to accommodate the proposed pipe replacements, nine stream crossings are
necessary Two of the stream crossings, Taggart Creek (S5) and an unnamed tributary thereto
(S7), will be performed via bore and hack, avoiding impacts to the two streams The remaining
seven stream crossings will be installed via excavation of a trench across the stream, resulting
in temporary impacts to two perennial streams, totaling 70 feet of impact, and to five intermittent
streams, totaling 195 feet of impact No permanent impacts to streams are proposed, and no
wetlands are present within the proposed project limits of disturbance Riparian buffer impacts
are exempt from the Charlotte - Mecklenburg buffer rules as the project consists of installation of
a utility line

3 Project Description
3a Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application
The site is located in the vicinity of the Charlotte - Douglas International Airport The project is composed of two segments,
the Paw Creek Force Main and the Taggart Creek Outfall The Paw Creek Force Main extends from the Paw Creek
pump station, located east of Paw Creek and north of Old Dowd Road, to the previously replaced section of Paw Creek
Force Main, which begins immediately east of 1-485 near the northwest corner of the Charlotte - Douglas International
Airport property The Taggart Creek Outfall collects flow from the Paw Creek Force Main near the northeast corner of the
airport property and runs south along Taggart Creek and Billy Graham Parkway, located on both sides thereof The
Taggart Creek Outfall turns to the east near the confluence of Taggart Creek and Irwin Creek to connect to the influent
pump station located at Irwin Creek Wastewater Treatment Plant (WWTP) Specifically, the project traverses wooded
areas, roadways, and cleared areas associated with residential, commercial, and industrial developments Portions of the
project are located in existing underground utility easements
3b List the total estimated acreage of all existing wetlands on the property
No wetlands have been identified within the project corridor
3c List the total estimated linear feet of all existing streams (intermittent and perennial) on the property
195 feet of intermittent stream and 130 feet of perennial stream are located within the project corridor
3d Explain the purpose of the proposed project
The purpose of the project is to eliminate flow restrictions in the existing pipes, replace aging infrastructure, and reduce
inflow and infiltration issues The project will also reduce aerial piping, increase system reliability, and reduce the risk of
sanitary sewer overflows (SSOs)
The Paw Creek force main connects the Paw Creek pump station to the Taggart Creek Outfall gravity sewer line, which
conveys flows to the Irwin Creek WWTP The Paw Creek force main is 24 inches in diameter at the pump station end of
the pipe and is 36 inches at the Taggart Creek Outfall end of the pipe The 24 -inch diameter segment of the Paw Creek
force main was constructed in the 1960s and its diameter is restricting the overall capacity The 24 -inch diameter
segment is proposed to be replaced with a 36 -inch diameter pipe from the Paw Creek Pump Station to the existing 36-
inch diameter segment
The Taggart Creek Outfall sewer was constructed in the 1970s, ranges from 15 to 24 inches in diameter, and crosses
Taggart Creek numerous times Five of the Taggart Creek crossings are aerial crossings, and the support piers are being
affected by the ground settling, resulting in difficulty maintaining adequate gravity flow and preventing blockages in the
pipe The Taggart Creek Outfall sewer is proposed to be replaced with a larger diameter pipe, ranging from 36 inches to
42 inches, which will be realigned to be located on the west side of Taggart Creek from the Paw Creek force main
function to the south side of Morris Field Drive and on the east side of Taggart Creek south to where it turns east towards
Irwin Creek WWTP along the north side of Irwin Creek The proposed pipe will cross Taggart Creek at one location
(trenchless crossing) and will be buried along the entire replaced length The increased diameter of the Taggart Creek
Outfall sewer line will allow Charlotte Water to direct all flows from the Paw Creek pump station through the Taggart
Creek Outfall to Irwin Creek WWTP

Describe the overall project in detail, including the type of equipment to be used
The project is proposed to be constructed in three phases The overall project includes replacing a portion of the Taggart
Creek Outfall gravity sewer and replacing the 24 -inch diameter force main from the Paw Creek pump station to the
existing 36 -inch diameter Paw Creek force main, which connects to the existing Taggart Creek Outfall gravity sewer The
Taggart Creek Outfall sewer line is being replaced in two phases, the Hope VI segment and the remaining segments
between the Paw Creek force main and the influent pump station at the Irwin Creek WWTP The Taggart Creek Outfall
sewer replacement comprises a total of 18,310 feet of 36 -inch and 42 -inch diameter pipe that will be realigned to
eliminate the numerous aerial crossings of Taggert Creek The Paw Creek force main will be realigned and replaced with
3,900 feet of 36 -inch diameter pipe, addressing the existing flow restrictions, and replacing the aging infrastructure This
permit application is the request for authorization of all three phases of the project
The first phase includes realignment of a portion of Taggart Creek Outfall pipe and replacement of approximately 1,610
feet of the Taggart Creek Outfall This segment of the pipe has been installed, but is not currently in service or connected
to other piping at either end This segment of Taggart Creek Outfall was installed with permission from NCDWQ and
USACE with the understanding that it be included in the current permit application The installed segment of the outfall
pipe is located entirely on the east side of Taggart Creek and Billy Graham Parkway, immediately west of the City of
Charlotte Housing Authority's (CHA's) Hope VI development, and north of West Blvd This segment of the pipe crosses
one intermittent stream, an unnamed tributary to Taggart Creek
The second phase of the project includes the remaining segments of the Taggart Creek Outfall Two segments of pipe
will be replaced, completing the replacement from the end of the Paw Creek force main to the Irwin Creek WWTP influent
pump station The second phase involves construction of 16,700 feet of Taggart Creek Outfall and removal and /or
abandonment of the existing gravity sewer lines
The third phase of the project includes the Paw Creek force main, which starts at the Paw Creek pump station and
extends 3,900 feet east to the existing 36 -inch segment of Paw Creek force main Phase 3 of the proposed project
completes the sewer replacement from Paw Creek pump station to Taggart Creek Outfall gravity sewer
The pipes will be installed via an open -cut trench, using coffer dams and a pump- around system for the seven open -cut
stream crossings The crossing of Taggart Creek and one unnamed tributary to Taggart Creek (S7) will be installed using
trenchless techniques In- stream construction will be performed in the dry Upon installation of the pipe, the native soil
material will be utilized to back -fill the trench, and the ground surface will be returned to the original grade and elevation
The stream banks will be repaired, returned to pre - construction elevations, stabilized with riprap and erosion control
matting, and planted with native vegetation, as specified in the attached drawing set Removal of the existing pipeline at
aerial crossings will involve entering the stream Materials will be removed under dry stream conditions, which will be
established and maintained by a pump- around system The equipment that is anticipated to be used to complete the
construction includes a pump, a backhoe, a trackhoe, a dozer, and /or a bore and hack

6 Future Project Plans
6a Is this a phased project? ® Yes ❑ No
6b If yes, explain
The project consists of three phases The first phase is the portion that has already been installed and is comprised of
the 1,610 -foot segment of 42 -inch diameter pipe of the Taggart Creek Outfall adjacent to the Hope VI site The second
phase includes the remainder of the proposed Taggart Creek Outfall replacements, consisting of 16,700 feet of pipe The
third phase comprises the proposed replacement of 3,900 feet of Paw Creek force main The decision to phase the
project was made due to the schedule for the construction of the retaining wall at the Hope VI public housing project as
the pipe was designed and constructed behind the retaining wall that was built to accommodate the redevelopment of the
Hope VI site The design was not completed for the portions of the project that comprise the second phase in time to
permit the project in a single phase prior to construction of the first phase Permission to install the first phase of the
project was granted by NCDWQ and USACE with the understanding that it would be included on the permit application
for the second and third phases of the project The pipe segment associated with the first phase of the project will not be
activated until the second phase of the project is constructed and activated The Taggart Creek Outfall segments that
comprise the second phase are anticipated to be constructed prior to the construction of the Paw Creek force main, which
is the third phase Phases 2 and 3 will be built under separate construction contracts independently of one another

D Impact Justification and Mitigation
1 Avoidance and Minimization
1a Specifically describe measures taken to avoid or minimize the proposed impacts in designing project
Avoidance of all impacts to jurisdictional waters can only be achieved by pursuing a no -build scenario, which does not address
the need for the project and is not possible at this time as Phase 1 has already been constructed A no -build scenario may
result in potential future impacts to water quality due to a failure of the aging infrastructure, resulting in a spill of raw sewage
into a jurisdictional stream Impacts have been minimized by locating the Taggart Creek Outfall along the east side of Billy
Graham Parkway and Taggart Creek south of Morris Field Drive, which (1) eliminated the need for demolition of two existing
residences on the west side of Billy Graham Parkway, (2) eliminated four aerial crossings of Taggart Creek, and (3) will bury
the single remaining crossing of Taggart Creek near Morris Field Drive The crossings of Taggart Creek (S5) and one
unnamed tributary to Taggart Creek (S7) will not result in any stream impacts as they will be installed using trenchless
techniques Permanent impacts to the unnamed tributaries to Irwin, Taggart, and Paw Creeks (S1, S2, S3, S4, S6, S8, and
S9) that are proposed to be crossed by the project are being avoided by burying the pipeline under the stream and returning
the stream to original grade and elevation following the installation The construction corridor at the stream crossings have
been reduced in width to 30 feet in order to minimize temporary impacts to the streams
1 b Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques
Crossings that will be installed in an open -cut trench will be constructed in dry stream conditions, with a pump- around and
check dam system in place, as needed, to eliminate stream flow in the construction area during the work at each stream
crossing The work is expected to be completed within one day per stream crossing, minimizing the length of time for which
the stream flow will be diverted through the pump- around system Erosion control measures, including silt fencing and riprap
on the banks above Ordinary High Water Mark, will be put into place to protect the streams from additional impacts Installing
the pipeline at every stream crossing via jack and bore method would result in the temporary loss of more forested areas due
to the area required for the bore pits The loss of mature vegetation that will occur if the jack and bore method is used for
every stream crossing will have a longer impact timeframe than the effects on the stream and the ecosystem thereof that will
result from the open -cut trench installation method
