Hello Stephanie,
• Please see attached P&N Statement.
• Regarding the riparian buffers, I am not contesting any of the blue line features' standard 50' buffer
designations in the project corridor so did not need to get the buffers formally approved by Johnston County.
• The crossings are currently planned as open cut although I am in discussion with USFWS and the ACOE regarding
the Black Creek Crossing which may be jack and bored due to possible Pigtoe.
Thanks and please let me know when is a good time to call you as I would like to discuss this project and the Old Raleigh
#4 Landfill as well.
I hope you had a great holiday as well and Happy New Year!
Alex

Alex,
I am currently reviewing the above referenced project and have the following questions:
• In your PCN application, it states see the attached purpose and need document. I cannot locate the document in
Laserfiche.
Can you please -mail me the document at your earliest convenience. Here is a link to Laserfiche to view the file:
httns://edocs.dea.nc.eov/WaterResources/Browse.asDx? id=1025924&dbid=0&reao=WaterResources
• Was a buffer determination conducted for the mapped features on the soil survey and USGS topographic map?
In the Neuse River Basin, intermittent streams, perennial streams, lakes, ponds and estuaries depicted on USGS
maps and NRCS soil survey maps are subject to the Riparian Buffer Rules. If a stream is depicted on either map it
is subject to the riparian buffers. [Note: if the permittee believes the maps inaccurately depict surface waters he

or she must consult the Division to secure a formal on -site determination. DWR's file review revealed that the
riparian buffers have NOT received formal verification by the Division.]
• Will the impacts to the wetlands and stream be via open cut? Will there be a maintained permanent corridor?
Thanks in advance and hope you had a nice holiday!

McGee's Crossroads Water District
NC 210 Water Main Improvements
Purpose and Need Statement
November, 2019
Project Description
The McGee's Crossroads Water District NC 210 Water Main Improvements project is necessary to
replace approximately 34,000 LF of existing 12-inch water main along Highway NC 210 from Old Stage
Road to Highway NC 50. The existing water main has experienced multiple breaks in the recent past and
the overall water distribution infrastructure in this area of the water district is experiencing on -going
problems. This main is the primary feed from Harnett County to the Water District and supplies the
McGee's Crossroads elevated water tank. Furthermore, Johnston County (JoCo) has a contract with
Harnett County to purchase up to 2.5 MGD and also has a contract with the Town of Fuquay-Varina to
supply up to 1.5 MGD, utilizing the existing water main along NC 210 to do so. The current water main
has insufficient capacity to receive 2.5 MGD from Harnett County and supply 1.5 MGD to Fuquay-Varina.
For these operational reasons and obligations, the McGee's Crossroads Water District proposes to
replace the existing 12-inch water main with approximately 34,000 LF of 12-inch and 20-inch water main
along NC 210 to provide reliable water service to the District customers and meet the supply and
demand requirements of the District.
Environmental
The project requires six (6) crossings of wetlands and streams to achieve the proposed water line
installation. Pursuant to Note 2 of the Nationwide Permit 12, each crossing is a single and complete
project. It is understood based on preapplication meeting with Ross Sullivan of the Army Corps of
Engineers (ACOE) on September 27, 2019 that the six crossings can therefore be processed as one
permit. Mr. Sullivan also reviewed the wetland and stream boundaries in the field on August 14, 2019
with no changes. It is requested that the Jurisdictional Determination (JD) be finalized with this permit
application. Please note that Crossing 6 at Camp Branch, although shown on the Wetlands
Determination Map, is located approximately 0.5 mile east of the Pond 2 location shown on the
Wetlands Determination Map. The only feature in this location is the stream Camp Branch as shown on
the inset map for Crossing 6.
The design of the water main replacement incorporates several measures to help reduce the potential
wetland/stream/buffer impacts. The water main has been designed with the intention of maintaining
the limits of disturbance within the existing public road right-of-way as much as possible to minimize the
area of jurisdictional features that will be encountered and impacted. A primary example includes the
water main alignment adjacent to the wetlands on either side of Black Creek. The majority of the
wetland area is avoided by maintaining the water main within the existing road right-of-way. In some
locations, the water main must be installed outside the right-of-way to avoid overlap with existing
utilities such as fiber optic conduit and cable or to avoid excessive installation depths under existing
storm drainage culverts/pipes. The required easement area outside the right-of-way in these instances
is minimized by using pipe fittings to go in and out of the right-of-way in a short span.

JoCo's Buffer Ordinance Table of Uses (part of Sec. 14-393 Riparian buffer protection (for lands within
the Neuse River Basin) includes perpendicular crossing of streams and other surface waters as "exempt"
if equal or less than 150 linear feet. All the crossings proposed meet with this requirement and therefore
no buffer mitigation is required or proposed. Additionally, the project is compliant with the superscript
requirements 2 and 3 in the Buffer Ordinance Table for perpendicular crossings such as hand clearing of
woody vegetation, stumps left in the ground, no fertilizer, etc. It should also be noted that most of the
buffer areas shown on the plans are within the existing maintained right-of-way for SR 210.
Where construction within the right-of-way limits allows, water mains are installed beneath storm
drainage pipes to minimize impact to stream channels and buffers. Wetland impacts were quantified as
temporary where the vegetation is currently herbaceous and will be herbaceous in future. Wetland
impacts that will result in forested conversion to herbaceous are classified as permanent, although no
fill will be placed in wetlands as a result of this project. No mitigation is proposed for impacts to streams
and wetlands as each crossing remains beneath the 1/101" acre threshold of wetland impact, with the
exception of the crossing at Black Creek, where 0.1124 acre of wetland impact is proposed. A
reservation of credit in the Neuse basin with private mitigation bank RES is in process and will be
provided separately to compensate for the 0.1124 acre of wetland impacts. Additionally, no mitigation is
required for the temporary stream crossings required to install the replacement water line. Stream and
wetland crossings will utilize directional trenching techniques with no change in pre -construction
contours of the waters of the US.
