4h. Explain the purpose of the proposed project: *
The purpose of the project is to stabilize the failing river -left stream bank so that it is no longer a threat to the residence and reduces/eliminates ongoing sediment impacts to Flat Creek
from this site.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used: *
The failing streambank is proposed to be stabilized using a combination of geotechnical and bioengineering design, engineering and construction techniques. Specifically, the toe of the
streambank will be stabilized using large (min. 31 x TW x TH) locally quarried/sourced boulders that generally match bedrock outcropping in the stream. Coffer dams will be constructed
as shown and detailed in the attached Plan Set, to catch woody debris and sediment to be removed before construction, as well as any debris that falls near the river -left bank during
construction. Turbid water trapped behind the coffer dams will be pumped to a filter bag(s) placed in an in a stable upland location. Project and filter bag discharge will not result in stream
turbidity greater than 10 NTU. Boulder toe stabilization will be constructed as shown in the attached Plan and will incorporate geotechnical design elements engineered by Gentry
Geotechnical Engineering (GGE). Boulder toe will be extended upward to an elevation greater than the opposite, river -right bank (the bank of a large stable mid channel bar/island, with
another channel of Flat Creek on its opposite, north side) near the project area so that high flows can not easily access the geo-lifts proposed above the boulder toe. The proposed work
would take place on the river -left bank of the river -left channel of Flat Creek. The river -right channel currently has capacity to accommodate additional flow as it is similar or larger in cross -
sectional area than the river -left channel, but currently conveys less flow than the river -left channel. Boulder toe will not extend into the stream farther than the natural streambank
extended before the subject slope failure occurred, or any further than needed to stabilize the slope (see attached photos). Sixteen -inch height, BioD-block geo-lifts will be installed per
manufacture specifications and the attached Plans, above bolder toe stabilization. Geo-lifts will be set back as shown maximizing slope stability and channel area as site conditions allow,
and will incorporate geotextile fabric as specified by GGE. Clean fill will be carefully placed within the geo-lifts as specified and approved by GGE. Temporary cut slopes and benches
necessary for geotextile installation will be stabilized per the attached plan and per contractor implemented techniques to prevent collapse and additional impacts to water quality. Similarly,
fill will be placed within geolifts from the top of the river -left bank with rare to keep fill out of the stream. Exposed edges of geo-lifts will contain enough topsoil and nutrients to provide a
medium capable of rapid temporary and permanent vegetation establishment. Vegetation proposed for the project is specified in the Plan and includes deep rooted, stabilizing, native
varieties of herbs and shrubs that exist elsewhere along the streambank and are appropriate to the ecosystem. Equipment used for the project will include, but may not be limited to, track
mounted excavators, loaders, dump trucks, compactors, and hand tools. Equipment operating from within the stream channel will be kept to the minimum necessary to complete the
project. Equipment will be checked for leaks and cleaned before entering the stream. Equipment operating in the stream channel will be operated from clean "mud mats" so as to impact
the channel as little as possible during work. Excavation and fill placement that takes place in or near the stream will be conducted in a manner that does not result in soil fill material being
placed in or near the stream channel, meaning that excavated or fill soil will be taken from its source and placed in machine buckets, truck beds, or containers without "double handling" by
placing on the ground in or near the stream. Soil erosion and sedimentation control (SESC) measures will be installed as a first step in the project and maintained throughout project
construction. Finally, a stormwater Swale and failed stormwater pipe historically discharging to the unstable river -left streambank will be rerouted and removed respectively to eliminate
local stormwater from flowing over the vulnerable slope. Every effort will be made to protect water quality in Flat Creek and construction of the project will be monitored on a frequent and
regular basis by both Quible & Associates, P. C. and GGE. This project description is included in the Plan as a Project Narritive.

E. Impact Justification and Mitigation O
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
Development of a detailed Civil and Geotechnical Bio-engineered plan to stabilize the failing streambank.
Application and receipt of all required permits from USACE, NC DWR, and the Town of Montreal before work begins.
Development of plans and specifications that clearly describe measures to be implemented to avoid and minimize temporary impacts to water quality
and that will likely enhance water quality and habitat over time including: natural channel design; SESC measures; material handling; equipment
operation; slope stabilization; etc.
Development of a plan that does not propose permanent water quality impacts.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Selection of a contractor that is licensed in the state of NC and has experience constructing natural channel design, slope stabilization, and
bioengineering projects. Provide and review plans with contractor. Conduct a preconstruction meeting(s). Make sure contractor understands the plans
and how to implement avoidance /minimization techniques. Frequent inspections by engineers to ensure construction techniques (mud mats, filter bags,
temporary and permanent slope stabilization, material handling techniques, and temporary and permanent vegetation establishment are being used.
