D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The proposed stream enhancement design will include some adjustment to the existing stream profile through the installation of log sill structures, but
stream alignment will remain the same thus minimizing overall impact. Stream banks will be laid back to allow stream flows to access floodplain, and
banks will be planted with a variety of native species to enhance the performance of the buffer.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
All stream channel construction work will be done in the dry and construction equipment will be checked to ensure no hydraulic fluid or oil is leaking
into the stream channel. At the end of each work day, all completed work will be stabilized prior to leaving the site.

Pre -Construction Notification
Section B. Project Information and Prior Project History
3d. The purpose of this project is to restore 250 LF of stream channel on a private tract of land. The
landowner wants to improve ecological function of the stream, and enhance wildlife habitat on his
property. Restoration will include reshaping and stabilizing the existing channel to allow access to the
bankfull bench and replanting the riparian buffer with native species.
3e. This project will include stream channel shaping and stabilization, including grading appropriate
dimension and profile for this watershed. Stream bank and bench grading, shaping and stabilization will
also be included. Construction will be completed with experienced stream restoration contractor.
Construction equipment such as track hoes and dump trucks will be used to construct improvements to
the channel and care will be taken to keep excess sediment and equipment out of the existing stream
channel. All channel construction work will be completed in the dry through the use of a pump around
operation.

Version 1.4
January 9, 2009
current soil survey and/or soil survey map sheets can be obtained from the local NRCS
County Office (hfp://www.nc.nres.usda.gov/). GIS soil layers are not acceptable.
M Vicinity map - Please clearly mark the location and approximate boundaries of the property
and project on the map. Please indicate north arrow and scale. Please include applicable
road names or State Road numbers.
R/The Site Plan - The most critical map to be provided is the site plan. You must provide full
sized plans. The following is the minimum list of plans that are typically needed.
R/Pre-construction/Pre-existing conditions - This sheet (or sheets) must include:
• All jurisdictional and non jurisdictional wetland, stream, water features, State regulated
buffers (delineated into Zones 1 and 2)
• Topographic contours with elevations
• Any existing structures and impervious areas
• Existing utility lines and easements
• Existing roads, culverts, and other pertinent features
• North arrow and the scale (1":50' scale is recommended).
�roposed conditions - This sheet (or sheets) must include:
• All jurisdictional and non jurisdictional wetland, stream, water features, State regulated
buffers (delineated into Zones 1 and 2)
• Lot layout (if a subdivision or commercial development is proposed) - lots must be
developable without further impacts to jurisdictional and non -jurisdictional wetlands,
streams, water features, and State regulated buffers. Building envelopes must be
provided when streams, wetlands, riparian buffers, or water features exist on a lot
• All built -out structures and impervious cover

wetland, or water features - if applicable)
• Impacted areas — these should correspond with the Impact numbers listed on your PCN
form.
NIP ❑ Drainage Plans - Final drainage plans must include the following:
• Locations and pertinent elevations and sizes of the stormwater collection* system and
drainage ways
• All inlets and outlets must also be shown with pertinent elevations (All outlets to
wetlands must be at a non-erosive velocity, generally less than 2 ft/sec during the peak
flow from the 10 -yr storm)
• Scaled stormwater BMPs must also be indicated as required by DWR rules and policies
• In certain cases (see Section E of PCN form), final stormwater management plans must
also be provided (see Stormwater Management Plan Checklist)
[Proposed Impacts - All impacts to jurisdictional and non -jurisdictional wetland, stream,
water features, and State regulated buffers must be shown and labeled on the site plans at
a scale no smaller than 1" = 50'. All excavation, fill, flooding, stabilization, and other impacts
that will be conducted in or near jurisdictional and non -jurisdictional wetland, stream, water
features, and State regulated buffers must be indicated. Please provide cross sectional
details showing the provisions for aquatic life passage (burial of culvert 20% for culverts s 48
inches, and 1 -foot for culverts > 48 inches).

Version 1.4
January 9, 2009
WIN Wetland Impacts:
❑ Precise grading and final elevation contours must be provided. Existing
vegetation and any clearing must be specified.
❑ All subsurface utility lines must indicate the location of anti -seep collars.
Construction detail for anti -seep collars must be provided.
❑ Roadway or other crossings of riparian wetlands may require floodway culverts to
maintain existing hydrological conditions.
❑ Plans should show that the hydrology of remaining wetlands on the site will be
maintained.
Stream Impacts:
Stream impacts must be clearly shown on the plans. The centerline as well as
the banks of the stream must be surveyed or located by GPS for the portion of
the stream to be impacted.
N/Q ❑ The inlet and the outlet of all culverts should be aligned with the stream as
much as possible. Inlet and outlet elevations and streambed elevations should
be indicated. Any inlet or outlet protection must be shown and enumerated on
the impact map(s).
NIQ� ❑ For bottomless culverts or other spans, a vertical cross section should be
provided that shows the minimum distance from each span to each stream bank,
the stream cross section, the height of the span above the stream and the
minimum distance from the edge of each footer to each stream bank.
Additionally, please provide a signed and sealed geotechnical report of
subsurface soils at the proposed bottomless culvert location. The report must
comply with the Division of Highways — Guidelines for Drainage Studies and
Hydraulic Design, prepared by A. L. Hankins, Jr., State Hydraulics Engineer -
1999.
NIN ❑ Multiple culverts or sectioned box culverts typically require the use of sills, off-
setting or other means to match the cross section of the existing stream (in order
to maintain stream stability and provide aquatic life passage). A vertical cross
section of the culverts should be shown overlain with the up and downstream
stream cross section including the stream flood -prone area.
N IA ❑ Impacts associated with dam construction must indicate and enumerate all fill
associated with the dam footprint, spillway and any bank stream bank
stabilization. The length of stream impounded must also be indicated and
enumerated.
