4a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application:*
The wasting project area consists of a wooded valley located between two capped and vegetated landfill mounds
within the Wilders Grove Landfill. Within the wooded valley is a 1,200 linear foot section of an unnamed tributary
to Crabtree Creek, which is the target reach for this stream restoration project. The eAsting stream channel is severely
incised, likely as a result of historically intense rain events and upstream urbanization. A severe 15 -foot vertical headcut
has formed and surrounding erosion has resulted in an approximately 20 -foot deep and 50 -foot wide ravine in the middle
portion of the project area. Mass wasting is evident with numerous large shrubs and trees having fallen into the stream
channel in recent months. Furthermore, significant erosion occurs during each large storm event vdth the stream banks
noticeably receding.

4h. Explain the purpose of the proposed project:*
The purpose of the proposed project is to improve the stability of the project site to prevent future erosion.
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:

The goal of this restoration is to produce a stable stream bed and bank throughout the project stream while providing
adequate channel to floodplain connectivity. This Will significantly reduce sediment loss throughout the project stream.
The proposed design will include channel modifications, channel relocation, bank stability improvements, grade control
structures, floodplain grading, and new upstream and downstream culverts.
The proposed design can be divided into three separate reaches: Upper Reach, Middle Reach, and Lower Reach.
The Upper Reach Will consist of a Priority 1 restoration, which includes replacing the existing incised stream with an
excavated Rosgen Type C stream channel connected to the historic floodplain. The new channel will include a more
consistent riffle -pool sequence, higher stream sinuosity, increased channel length, and overall reduced channel slope.
Stable 2:1 to 4:1 side slopes will be utilized throughout the Upper Reach, which, along With an appropriate planting plan,
Will result in improved bank and floodplain stability. Furthermore, constructed riffles Will be installed for enhanced stream
bed stability. Boulder vane arms and boulder cross vanes Will be installed to deflect erosive flows away from stream
banks and provide necessary grade control throughout the reach. Boulder structures have been proposed as opposed to
wood structures due to the low flow conditions throughout the project stream and the tendency of woody material to
degrade when not submerged.
The Middle Reach will consist of constructed riffles, a boulder step -pool sequence, and a more pronounced series of
boulder grade control structures. Large boulders and appropriately sized bed material will be utilized throughout this
steeper, minimally sinuous reach to provide a stable stream channel and necessary grade control. Significant elevation
change is required in this Middle Reach in order to connect the Priority 1 Upper Reach and Priority 3 Lower Reach.
The Lower Reach will consist of a Priority 3 restoration with the objective of widening the available floodplain while
keeping the stream bed near the existing elevation. This Will be accomplished by excavating floodplain benches in the
upper portion of this reach and modifying the existing channel dimensions throughout the reach based on stream
reference data. The proposed stream will be a low slope, Type B channel that Will reduce shear stress throughout the
reach.
Additionally, the 60 -inch CMP culvert and the 48 -inch HDPE culvert located on the upstream and downstream ends of the
project stream Will be replaced. Both the upstream and downstream culvert crossings will be replaced by a primary instream
culvert and two floodplain culverts. The in -stream culvert Will convey base flow and smaller storm flows plus the
majority of flow for larger storm events. The floodplain culverts will be active during larger storm events and allow
floodplain flow to be conveyed through the access road crossings. At both the culvert crossings, the in -stream culvert Will
be an aluminum 60 -inch culvert with beveled end sections. Large sized riprap will be placed around the in -stream culvert
and grouted for added stability. The floodplain culverts will be aluminum 36 -inch culverts also With beveled end sections.
Native vegetation will be established Within and adjacent to the proposed stream; further enhancing bank and floodplain
stability while providing valuable habitat. A riparian buffer permanent seed mixwill be established Within the limits of
disturbance. The permanent seed mix was selected based on project location, soil type, and anticipated moisture
conditions. A nurse crop of barley, winter rye, brown -top millet, or pearl millet will be utilized to initially establish
vegetation on disturbed slopes.
Live stakes and plant plugs Will be established along the stream bank for adequate root zone and further stabilization.
Furthermore, bare root trees and shrubs will be planted throughout the floodplain and upland areas disturbed during
construction. Full detail of the planting plan can be found in the Wilders Grove Stream Restoration project plans.
Equipment to be used may include but Will not necessarily be limited to: excavator, dump truck, bulldozer, skid steer.

E. Impact Justification and Mitigation

1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
The stream restoration plan was designed to achieve project objectives while limiting the overall area and soil disturbance necessary. Priority 1
restoration was selected for the Upper and Middle Reach so that a new stable channel could be cut within the existing floodplain and the produced cut
could FII the existing eroded ravine. This design will eliminate the large headcut at the middle portion of the project Which has been a major driver for
erosion. Clearing and grubbing of trees and vegetation will be limited to areas necessary to facilitate the stream restoration and relocation. Most
impacts will be temporary and the overall project will result in significant decline in erosion and sediment load lost from the site.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Clearing, grubbing, and disturbance will be limited to the areas necessary to facilitate stream restoration and relocation. Erosion and sediment control
techniques and structures including silt fence, specified stockpile areas, construction entrance, tree protection, sediment ditch checks, and erosion
control blankets will be used throughout construction. Pump -around stream diversions will be used to ensure that all in -stream construction will be
conducted in dry conditions. Additionally, a construction access road will be implemented to reduce the area exposed to construction vehicle traffic.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
r Yes r No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
Stream restoration is listed as exempt on the Neuse River Basin Buffer Protection Rule.
F. Stormwater Management and Diffuse Flow Plan (required by DWR)
1. Diffuse Flow Plan
1a. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?
r Yes r No
If no, explain why:
Stream restoration activities are exempt from buffer rules and mitigation is not required. The riparian areas
disturbed during restoration activities will be revegetated and replanted with native vegetation.
2. Stormwater Management Plan
2a. Is this a NCDOT project subject to compliance with NCDOT's Individual NPDES permit NCS000250?*
r Yes r No
2b. Does this project meet the requirements for low density projects as defined in 15A NCAC 02H .1003(2)?
