D. Impact Justification and Mitigation
1 Avoidance and Minimization
la Specifically describe measures taken to avoid or minimize the proposed Impacts in designing project
The limits of disturbance were minimized to limited access around the stream Existing trees will remain as much as possible along the stream corridor
and buffer The construction equipment will only be allowed to cross the stream at the temporary crossing indicated on the plans
lb Specifically describe measures taken to avoid or minimize the proposed Impacts through construction techniques
Equipment will be kept above the stream and construction will only occur in the limits of disturbance Seeding, matting, and installation of woody
vegetation will occur in all disturbed areas shown on the planting plan for buffer re- establishment and stabilization

B Project Information and Prior Project History
3a Project Description
The project is located in a residential neighborhood involving a tributary to Hare Snipe Creek located in
the back yards of 6613 and 6617 Mafolie Court The project also extends onto a property owned by the
City of Raleigh at 3330 Leesville Towns Court The 243 acre developed watershed for the project is
approximately 80% single family residential development with some multifamily residential The stream
is actively eroding and is causing mass wasting of the banks into the stream At the two properties on
Mafohe Court the stream forms two horizontal bends The outside of the bends are experiencing the
most erosion The stream is severely entrenched with 6 -8 foot banks that in some areas are vertical or
undercut
3b Acreage of wetlands
No wetlands were found within the project area it is unknown if additional wetlands occur on the
extents of all three properties
3d Explain the purpose of the project
The property owner has requested the City of Raleigh's assistance in stabilizing the stream banks at
6613 and 6617 Mafolie Court The project will stabilize the banks and re- establish woody vegetation for
long term stabilization
3e Describe the overall project in detail including the type of equipment to be used
Reshaping of the eroded bank and the introduction of rock and vegetation are proposed for this project
Due to the streams current state of incision and stream velocities rock toe stabilization and soil lifts
were utilized for the design of this project The severe erosion in the outer meander bends will be
stabilized with a rock toe Grading on 6617 Mafolie court will tieback into the existing grade using 3
vegetative lifts, to tie into existing terrace grades The remaining meander outer bank toe will be
reinforced with a rock toe and the bank will be re- graded to a 2 1 slope A rock toe is also proposed to
be placed in three other outer bend locations The repairs have been proposed in areas of stress along
the stream Banks that are not marked for repairs that are currently in stable conditions will remain at
their present grades The existing point bar within the channel will be removed as a part of the repairs
The project ends with bank regarding on the City of Raleigh Property Steep banks and erosion was
occurring in this area. The downstream end of the project ties in to a stable bank with existing
vegetation All disturbed areas will be seeded, matted, and planted with rooted plant plugs for long
term stabilization
The equipment to be used in the project is earth moving equipment and various other support
apparatuses. Heavy equipment may include hydraulic excavators, compactors, bulldozers, skidsteer
loader, and dump trucks to load and unload materials The construction equipment will enter off of

Mafolie Court and will perform all construction within a defined limit of disturbance. The construction
equipment will cross the tributary at one location defined as a temporary stream crossing on the
construction drawings
F. Supplementary Information
5d What data sources did you use to determine whether your site would impact Endangered Species or
Designated Critical Habitat?
The site is an existing urban residential area that has been previously impacted by development Habitat
is not present for Wake County listed vertebrate and invertebrate endangered species Michaux's sumac
prefers open areas and is relatively shade tolerant The site is forested with other open areas currently
being mowed There should not be any associated T/E issues

Erosion Control Matting / Coconut Fiber (Coir) Blanket (C -700)
Description
The coconut fiber channel lining shall be a machine- produced 100% biodegradable mat
The blanket shall be of consistent thickness with the coconut fiber evenly distributed over
the entire area of the mat Coconut Fiber Blankets will only be used in locations specified
by the Engineer. Locations will be on all disturbed streambanks prior to turning the
streamflow into the newly constructed channel. Other problem areas may also require the
placement of coconut fiber blankets.

Stakes will be wooden stakes 12 in. (300 mm) in length with a notch cut 1 in (25 min)
from the top These stakes shall be used to stake the matting along the slopes. Wooden 3
ft. stakes spaced approximately 4 ft. apart shall be used to secure the matting at the toe of
the slope The toe stakes shall have a minimum 1 -inch by 1 -inch cross - section and shall
be designed so that the matting can not slide past the exposed end of the stake
Construction Methods:
Provide a smooth soil surface free from stones, clods, or debris that will prevent the
contact of the matting with the soil. Place the matting immediately upon final gradmg.
Take care to preserve the required line, grade, and cross section of the area covered All
cut slopes shall be stabilized at the end of each working day with erosion control matting
Apply fertilizer, seed, line, and straw mulching prior to installing the matting.
Prepare the soil beneath the matting with topsoil if required, seed, fertilizer, and cover
with straw mulch. Unroll the matting and apply without stretching such that it will lie
smoothly but loosely on the soil surface Bury the top slope end of each piece of matting
in a narrow trench at least 6 inches (150 mm) deep and tamp firmly Where one roll of
matting ends and a second roll begins, overlap the end of the upper roll over the buried
end of the second roll so there is a 6 inches (150 mm) overlap. Construct check trenches
at least 12 inches (0 3 m) deep every 50 feet (16 m) longitudinally along the edges of the
matting or as directed by the Project Engineer. Fold over and bury matting to the full

depth of the trench, close and tamp firmly Overlap matting at least 6 inches (150 mm)
where 2 or more widths of matting are installed side by side
Place stakes across the matting at ends, functions, and check trenches approximately 1
foot (90.3 m) apart with notch facing upslope. Place stakes along the outer edges and
down the center of each strip of matting 3 feet (1 meter) apart. Place stakes along all
lapped edges 1 foot (0.3 m) apart. Refer to details in the plan sheets.
The Engineer may require adjustments in the trenching or staking requirements to fit
individual site conditions.
Basis of Payment
The quantity of "Erosion Control Matting /Corr Matting" measured as provided above
will be paid for at the contract unit price per square yard for "Erosion Control
Matting/Coconut Fiber (Coir) Blanket" and shall include all work and materials required
in this section. Payment for staples, stakes, and twine will be included in the contract unit
price for "Erosion Control Matting ".
