Notes:
Construction will occur in the dry using a pump
around technique to prevent working in flowing
water. A cofferdam will be constructed using a
non -erosive barrier and a pump will be used to
carry the stream flow around the work area. A
smaller de -watering pump will also be used to
remove any water that seeps into the work
Stabilization will occur by placing seed and
straw on the banks and floodplain of the
restoration reach. Areas adjacent to the
stream will be stabilized with a native
wetland/riparian seed mix and be covered with
straw and coir matting. Disturbed areas which
are not directly abutting or adjacent to the
stream will receive seed, straw, and matting.
Woody vegetation will be planted for long term
stabilization as 100 live stakes consisting of 50
black willow and 50 elderberry. The live stakes
will be planted during the dormant season.
Two log vanes and one rock step pool are
proposed at a slope of 6.8 % (0.068 ft/ft). All
grade control structures will be wraped in
non -woven filter fabric and backfilled with riffle
Rock to be used for the riffle substrate should
be natural stream rock with an approximate
size of small cobbles (64-128 mm) and a 84th
percentile of approximately 80mm.
