4h. Explain the purpose of the proposed project:*
The purpose of this project is to stabilize approximately 2,600 linear feet of unstable streambanks on an unnamed tributary (UT) to the Second Broad River and small UT to the UT Second
Broad River. Natural channel design techniques including log j-hooks, log vanes, boulderj-hooks, bank grading to a stable slope, brush toe revetments, rock toe revetments, and a
permanent native woody riparian buffer will be installed for long-term stability. Cattle will be fenced out of the stream corridor to improve water quality and protect the stabilized
streambanks.
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used: *
Tracked excavators will be used to grade stream banks, install in - stream structures and bank revetments, and perform general site grading. Skid steers and dump trucks will also be used
to move earth and materials. Graded streambanks will be stabilized with biodegradable coir matting and/or vegetated sod transplants. Construction crews will divert the majority of
baseflow around the work areas by constructing a temporary gravel/cobble diversion. Any offline sections of stream channel will be built in the dry and stabilized before diverting water into
the new channel.
A qualified stream restoration contractor will be doing the grading work.
See attached plan sheets for additional details.

1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
Stream restoration is needed to achieve ecological objectives and enhance water quality within the project reach and areas downstream. Impacts will be
minimized by maintaining as much as possible the existing stream channel and any existing natural riparian buffer. Impacts will be acute and short-term,
but will result in long-term benefits to aquatic resources.
lb. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Disturbance will be minimized to the extent possible. Work will be conducted from the stream banks to limit channel disturbance. A pump - around
operation will be utilized when working in the smaller UT. Due to the size of the main stem UT to Second Broad watershed, it is not feasible to pump
around the baseflow on this reach. When installing in -stream structures, construction crews will divert the baseflow around the work areas by
constructing a temporary gravel/cobble diversion. All instream work shall be conducted so that the flowing stream does not come in contact with the
disturbed area. The stream channel will not be used as a construction access route. Any offline sections of stream channel will be built in the dry and
stabilized before diverting water into the new channel.
Channel banks will be stabilized with seeding, straw, and biodegradable coir matting and/or vegetation transplants and planted with a permanent woody
buffer during the appropriate planting season See plans for additional details.

Stormwater accumulated within the washout may not be pumped into ordischarged to the storm drain system or receiving surface waters. Liquid waste mustbe pumped out and removed from project.6. Locate washouts at least 50 feet from storm drain inlets and surface waters unless itcan be shown that no other alternatives are reasonably available. At a minimum,install protection of storm drain inlet(s) closest to the washout which could receivespills or overflow.7. Locate washouts in an easily accessible area, on level ground and install a stoneentrance pad in front of the washout. Additional controls may be required by theapproving authority.8. Install at least one sign directing concrete trucks to the washout within the projectlimits. Post signage on the washout itself to identify this location.9. Remove leavings from the washout when at approximately 75% capacity to limitoverflow events. Replace the tarp, sand bags or other temporary structuralcomponents when no longer functional. When utilizing alternative or proprietaryproducts, follow manufacturer's instructions.10. At the completion of the concrete work, remove remaining leavings and dispose ofin an approved disposal facility. Fill pit, if applicable, and stabilize any disturbancecaused by removal of washout.EARTHEN STOCKPILE MANAGEMENT1. Show stockpile locations on plans. Locate earthen-material stockpile areas at least50 feet away from storm drain inlets, sediment basins, perimeter sediment controlsand surface waters unless it can be shown no other alternatives are reasonablyavailable.2. Protect stockpile with silt fence installed along toe of slope with a minimum offset offive feet from the toe of stockpile.3. Provide stable stone access point when feasible.4. Stabilize stockpile within the timeframes provided on this sheet and in accordancewith the approved plan and any additional requirements.
