Construction sequencing:
1) Contractor shall steak out proposed stream and stream bed alignment.
2) Install pump around. All stream work shall be conducted in the dry.
3) Grade stream, stream bed alignment, and flood prone bankfull bench to elevations specified on Drawings 1
through 4. Streambanks shall be laid back smoothly and gradually as indicated on Drawing 4 and as shown
in photograph on Drawing 9. Sheer or steeply sloping stream banks are not permissible.
4) Install log drop (Drawing 6) structures at locations and invert elevations specified on Drawing 3.
5) Install filter fabric on up -gradient sides of log drop structures as specified (Drawings 6).
6) Prepare finish grades around structures and Streambanks. Excavate riffle sections to allow for installation of
riffle bed material at specified finished streambed elevations to be installed following installation of coir
fiber matting on stream banks (riffle sections only).
7) Seed and straw along stream banks.
• Use Native Wetland Seed Mix to specifications per seed mix. Generally, 1/2 lb. per 1,000SF should be
applied.
• A contractors blend of permanent and temporary seed shall be applied in addition to the wetland seed
mix.
7) Install woven geotextile blanket composed of 100% biodegradable, natural coconut (coir) fiber matting over
seeded and strawed stream banks. Note: matting shall extend from stream bank toe slope to beyond top of
bank.
8) Install riffle materials (Drawing 7) within riffle sections to elevations specified on drawing 4, while
overlapping erosion control coir matting on stream banks. Riffles shall be tamped with the knuckle to clear
voids, create a thwalweg within the channel and achieve the specified elevations.
9) Ensure final grades on remainder of project area, including bankfull benches.
10) Seed and straw the remainder of the disturbed areas.
• Use Native Wetland Seed Mix to specifications per seed mix within the flood prone benches. Generally,
1/2 lb. per 1,000SF should be applied depending on seed mix.
• A contractors blend of permanent and temporary seed shall be applied in addition to the wetland seed
mix and on remainder of disturbed areas.
11) Install coconut fiber erosion control coir surface blanket (0.5 lb/yd2) over areas not subject to stream flow
and as needed for sloping areas.
12) Install black willow live stakes (Drawing 10).
Live stakes shall be placed at a minimum spacing of 3 x 3 feet on the outside bank of restored stream
meanders. Spacing shall be a minimum of 2 x 2 feet adjacent to grade control devices. Spacing shall be
a minimum of 6 x 6 feet along the remainder of the stream banks.
13) Install trees and shrubs in stream buffer revegetation area as specified within the planting plan (Drawing 10).

LOG DROP: Construct log drop structures by first shaping the channel to the grades specified, including scour pools.
Next, excavate enough bed material to place the logs, filter fabric and gravel overlay. Placement of logs shall extend a
minimum of three feet into stream bank. First, place footer log and then check the elevations on stream bottom and tie
into the bank. Place header log on foundation log and secure with rebar in accordance with specified plans. Logs can
be tied together in lieu of rebar depending on field conditions. If logs are tied together, then the footer log should be
off -set from the header log by 1-2 inches down -stream. The maximum offset of header and footer logs should not
exceed 3 inches down -stream. Header log should be set 3" above final structure invert. Backfill edges of logs and cut
notch to specified invert. The logs shall be placed tightly together to minimize gaps. Stable or nail filter fabric at the
upstream end of the structure as shown on the drawings and backfill with gravel to seal any gaps. Fill the voids on the
upstream side of surface logs with gravel such that water will flow over the surface logs rather than through gaps in
the logs.
• LOGS: Use logs that are straight, uniform diameter and free of rot, disease and insect infestation. Use only hardwood
tree species, with exception of tulip poplar. Logs shall be a minimum of 12 inches in diameter and 12 feet in length.
• FABRIC: Filter fabric shall consist of a non -woven geotextile fabric with a minimum weight of 8oz/sy. Riffle shall be
constructed after placement of logs and filter fabric.

• RIFFLES: Bed material aggregates shall be gravel or crushed stone. Aggregates shall be composed of clean, hard,
durable, mineral particles free from organic matter, clay balls, soft particles, or other substances that would interfere
with the draining properties of the aggregates. This material shall be placed with typical thickness of less than 24
inches. Either use an approved stock -pile of river alluvium or mix equal parts riprap, 2-6-inch diameter (0.5 to 11
lbs.) and 57 stone, %2-inch to 11/2 diameter. The surface of placed bedding material shall be thoroughly chinked and
filled with the smaller stones by scattering and tamping.
• Final Grade: Following construction of in -stream structures, the channel shall be final graded to provide a smooth
transition around the structures and between proposed and existing slopes in preparation of final restoration. The
constructed stream channel shall be restored as soon as possible by seeding in accordance with these plans and
specifications. The excavated channel shall be fully restored and vegetated, if possible, before flows are introduced to
the new channel.

Typical view of constructed flood prone bankfull bench. Note the use of coir matting on lower stream channel banks.
• The contractor is to install a bankfull bench and lay back the stream banks to the extent possible to match existing
contours, similar to the typical view shown above. The proposed stream channel shall be constructed by excavating
the flood prone area adjacent to the channel to the bankfull elevation as instructed by Pilot. All excess material
generated shall be wasted in upland areas.
• Disturbed areas shall be reseeded and covered with straw. A temporary and permanent seed mix shall be applied to
ensure immediate and long-term vegetative cover. The bankfull sections should be reseeded with a wetland seed
mix.
• Disturbed areas subject to stream flow shall be covered with woven geotextile blanket composed of 100%
biodegradable, natural coconut (coir) fiber and staked in accordance with manufacturing specifications.
• The remaining disturbed areas shall be covered with coconut fiber erosion control coir surface blanket (0.5 lb/ydz)
and staked in accordance with manufacturing specifications.
