III. Certification Statement:
I !3J"o lo,nit i U±J certify to the best of my knowledge that the addition of
the volume of wastewater to be p rmitted in this project has been evaluated along the route to the receivin
wastewater treatment facility and that the flow from this project is not anticipated to cause any capacir
related sanitary sewer overflows or overburden any downstream pump station en route to the receivin,
treatment plant under normal circumstances, given the implementation of the planned improvement
identified in the planning assessment where applicable. This analysis has been performed in accordant
with local established policies and procedures using the best available data. This certification applies t.
those items listed above in Sections I and II plus all attached planning assessment addendums for which
am the responsible party. Signature of this form certifies that the receiving collection system or treatmen
works has adequate capacity to transport and treat the proposed new wastewater.

The included package is a submittal for Angier Avenue Townhomes for review and approval. The subject
site is located at 4115 Angier Avenue in Durham, NC. Currently the site is undeveloped woodlands and
the project is 115 Residential Townhomes with accompanied parking, utilities, and stormwater system.
Specifically, the project has 78' of 8" DIP gravity sewer from the site and connecting to an existing
manhole in Angier Avenue. The total calculated wastewater amount flowing through the system will be
41,400 GPD (this flow will be permitted under a separate private permit) which includes all proposed
buildings and facilities on site. The system flows to a Durham County Pump Station via gravity and
eventually discharges to the Triangle WWTP.
Included in this package is the following:
• Fast track Sewer System Extension Application
• Flow Tracking for Sewer Extension Application
• Aerial Map of Site
• USGS Topo Map
• Utility Plans
• Check in the amount of $480.00
Should you have any questions regarding this project or require additional information, please do not
hesitate to contact me at [phone].
