Fast Track Application for Public Gravity Sewer Extension at
Alexander Place Townhomes — Durham, NC
NC Dept of Environmental Quality
MAY 21 2019
Raleigh Regional Office
The site is located in Durham City limits, but the sanitary sewer flows will be collected by
Durham County.
The project consists of a 26.08 acre site with no existing buildings or infrastructure. The
proposed project is a 157 unit (three bedroom) townhome community with supporting
infrastructure. The new gravity sewer system for the project will be private inside the project
property. The private ssanitary sewer will tie to a new public sewer extension north of the
intersection of NC HWY 55 and TW Alexander Rd (SR 2028).
The public sanitary sewer for the project will consist of the following:
8-inch gravity sanitary sewer main
• 8 Inch DIP (186 LF)
The sanitary sewer flow allocation required for this project will be:
No flow associated with this project. All flow is associated with private sewer extension.

III. Certification Statement:
I Stephanie Brixey certify to the best of my 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 II plus all
attached planning assessment addendums for which I am the responsible party. Signature of this
form indicates acceptance of this wastewater flow.
