Sent:Monday, April 04, 2016 8:57 AM
To:Smith, Cherri L
Cc:'Alexander, Tasha L SAW'; 'Rachael Cooper'
Subject:Revised PCN Turnipseed Nature Preserve
Cherri:
Please find attached the revised PCN with adjustments to NWP numbers based on conversations with Tasha Alexander,
removal of wetland pile impacts, and buffer impacts split out to identify impacts at Bridge A and B separately. Also
attached is a revised page 3 from our supplemental word document describing the buffer impacts and revised impact
maps. I have not received the letter yet regarding the stream identification confirmation from the field visit with
NCDENR staff. That letter may have gone to the owner. Please let me know if you require any additional information or
if you need anything else.
Thanks,

Several picnic areas will be located adjacent to each parking area. The trail system will consist of a 6 -
foot wide screened trail with 2 -foot grassed shoulders and will be constructed on grade where possible.
Standard 10' boardwalks 15 -inch RCP pipe crossings are proposed to be used for crossing small streams
and tributaries along the trail. Two bridges are proposed to cross streams and wetlands along the trail
corridor. Bridge A is a 10 -foot wide, 30 feet long bridge proposed to cross an unnamed stream
downstream of the existing dam. Bridge B is a 10 feet wide 120 feet long bridge to span the floodway
and the wetlands of Gin Branch with boardwalk joining to each abutment to connect the trail back to
natural grade. A construction road will be cleared for equipment access to Gin Brach to construct the
bridge and boardwalk. The contractor will be starting on the interior of the park and working out as they
construct the trails. The contractor will cross UT to Gin Branch with temporary bridge mats and will
construct the bridge and boardwalk from both sides of Gin Branch within the limits of disturbance as
shown on the plans.
It is anticipated that earth moving equipment will be used for the project including but not limited to
excavators, loaders, and dump trucks. A crane will most likely be required to set the bridge over Gin
Branch.
C. Proposed Impacts Inventory
6i Buffer Impacts Comments:
B1 temporary impacts include area within the buffer that will be required to be used for
temporary access to construct the proposed improvements at UT to Gin Branch for
Pedestrian Bridge A.
B2 temporary impacts include the area within the buffer that will be required to be used for
temporary access to construct the proposed improvements at Gin Branch for Pedestrian
Bridge B.
B3 permanent impacts include the area of the proposed trail, bridge, and concrete footing that
will be installed in the buffer of the tributary to Gin branch downstream of the existing
pond for Pedestrian Bridge A that will be constructed within the buffers.
B4 permanent impacts include the area for the bridge, bridge abutments, and boardwalk for
Bridge B across Gin Branch that will be constructed within the buffers.
E. Stormwater Management and Diffuse Flow Plan (Required by DWQ)
3c. Stormwater Management Plan: A copy of the stormwater impact analysis has been submitted to
DWQ along with the PCN. The plan has been submitted to Wake County and an approval letter will be
submitted to DWQ upon receipt.

3i. Comments:
NA - A bridge mat will be installed over UT to Gin Branch downstream of the existing pond to provide access for construction equipment. This bridge
access mat will be installed to span from top of bank to top of bank. No construction equipment will be allowed to cross the tributary other than at this
location. The construction for the bridge over Gin Branch will be accessed from either side of the stream no construction equipment will be permitted to
cross the stream. Therefore no stream impacts are anticipated for this project that would impair stream function.

Impact Justification and Mitigation
1.
Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Trails and parking lots were designed to remain outside of buffers and wetlands. The streams have been crossed with elevated bridges and
boardwalks to avoid channel impacts.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Equipment will not cross at Gin Branch. Construction equipment will not be allowed to cross the stream only at locations with temporary bridge mats. All
work in wetland areas will be performed from bridge mats.

If this project DOES require a Stormwater Management Plan, then provide a brief, narrative
description of the plan:
A stormwater impact analysis was completed for the project and has been submitted to Wake County for review and approval. Both peak flow and
nitrogen export were investigated in the report. Detention was required by Wake County at both proposed parking lots. The nutrient export with the
proposed improvements is within the allowable amounts for the Neuse River Basin and therefore a BMP for nutrient removal was not required. One
copy
of the stormwater impact analysis document has been been provided as a separate document to DWQ.
The approval letter will be will be made
