Little Beaver Creek Sewer and Friendship Station Phases 1-4 — Updated Wetland Impact Table
c
`' Initial impact will result from clearing for the sewer easement; road impact will occur in the future when final design is completed, and the Friendship Station
project is ready to expand into this area.
0.27 acre of PFO impact resulting from forested wetland clearing are proposed to be mitigated for with this current PCN.

This information is intended to replace that in the original PCN since we are now permitting the sewer and phases 1-4 of Friendship Station. The
applicant and owner info is the same and the other description previously provided remain accurate. Updated wetland and stream tables are
included as well to replace those from the original PCN
Purpose and Need Section 4h from electronic PCN submittal
The purpose of the project is to provide sewer to Friendship Station and other future sites in this area. Wetland clearing and temporary impacts
to wetlands and waters is necessary to construct the sewer line. Friendship Station will provide residential housing to the area. Phases 1-4 incur
minimal impacts to wetlands and waters and are required primarily for a road crossing.
Project Description Section 4i from electronic PCN submittal
Imminent phases of the Friendship Station project include phases 1-4 and the development of single family lots and townhome lots along with
all public infrastructure to serve these phases of the development. Additionally, the Little Beaver Creek Sewer Outfall will be constructed to
serve phases 1-4 of the development. Impacts associated with phases 1-4 and the Little Beaver Creek Outfall have been reflected on sheet 2 to
show temporary wetland and stream impacts and one permanent stream impact to be permitted now.
Future phases of the Friendship Station development include phases 5 & 6 of the development that will include single family lots and all public
infrastructure to serve them. Future construction of Olive Farm road that crosses Little Beaver creek will connect phases 1-4 to phases 5 & 6.
Additionally, future construction shall include a road connection to the existing Woodbury subdivision. All future impacts to streams and
wetlands have been called out on sheet 1 including an imminent temporary wetland impact that will become a permanent wetland impact once
the connection to Woodbury subdivision is made.
Both the present and future activities for this project are under the current NWP thresholds as defined by USACE during this permit review
process. This current request is for the LBC sewer outfall and Friendship Station 1-4 only. Both wetland and stream mitigation are being
provided per the USACE requirements.
Avoidance and Minimization Section E 1a from electronic PCN submittal
The route of the sewer line has been designed to avoid large wetland impacts and is configured to cross at narrow points of those wetlands
affected, where practicable. The corridor is the narrowest allowed by the Town of Apex. Stream impacts from the sewer line are temporary and
will be returned to pre -construction contours. The engineer has designed the FS 1-4 site plan to avoid wetland impacts. There is one road
crossing that will affect 98 feet of intermittent tributary. The crossing has been designed to minimize impacts as much as practicable.
Section E 1b from electronic PCN submittal
All applicable ESC measures will be strictly maintained during the construction phases of the project. Monitoring will be conducted to ensure
the measures are functioning properly. Cleared areas will be revegetated and any excess spoil will be removed from any areas near aquatic
resources.
