PROJECT LOCATION
The site is located along Kensington Drive in Union County, NC, roughly 1,900 linear
feet southwest of the intersection of Kensington Drive (SR 1305) and Waxhaw-Marvin.
Road (SR 1301).
PROJECT DESCRIPTION
Ryland Hornes is constructing a 20 lot single-family neighborhood on the 20.3-acre site.
All lots will be served by public sewer lines that connect to an existing public sewer main
in the southwestern corner of the lot.
The sanitary sewer design for this project includes the installation of 1,455-1inear feet of
8-inch PVC and ten (1.0) proposed manholes. The estimated wastewater flow was
calculated. using an average daily flow of 95 gallons per day per bedroom. Each home
will have 3 bedrooms and there are 20 homes. The estimated wastewater flow is 5,700
gallons per day.

n Statement.
Grants certify t.o the best ofmy 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 If
plus all attached planning assessment addendums for which I am the responsible party.

FTSE PLANNING ASSESSMENT ADDENDUM (PAA)
Submit a planning assessment addendum for each pump station Listed in Section II where Available
Capacity is < 0.
Pump Station (Name or Number):
Given that:
a. The proportion and amount of Obligated, Not Yet Tributary Daily Flow (C) accounts for
and MGD of the Available Capacity (E) in Pump Station
; and that
b. The rate of activation of this obligated, not yet tributary capacity is currently approximately
MGD per year; and that
c. A funded Capital Project that will provide the required planned capacity, namely
is in design or under construction with
planned completion in ; and/or
d. The following applies:
Therefore:
Given reasonably expected conditions and planning information, there is sufficient justification
to allow this flow to be permitted, without a significant likelihood of over -allocating capacity in
the system infrastructure.
I understand that this does not relieve the collection system owner from complying with G.S.
143-215.67(a) which prohibits the introduction of any waste in excess of the capacity of the
waste disposal system.
