Sequence of Construction:
1) Begin stream-work at upstream project extent Station 0+00 -
2+50:
a) Slope erodible streambanks b) Install Boulder Wall
and in-stream structures c) Stabilize all areas of
disturbance with coconut matting, seed, and livesakes.
2) Continue stream-work from Station 2+50 - 5+50:
a) Slope erodible streambanks b) Install bridge armor and in-
stream structures c) Stabilize all areas of disturbance with
coconut matting, seed, and livestakes.
3) Continue stream-work from Station 5+50 - 9+50:
a) Slope erodible streambanks b) Install boulder toe
protection, bridge armor, and in-stream structures c) Stabilize
all areas with matting, seed, and livestakes.
4) Continue stream-work from station 9+50 -11+80:
a) Slope erodible streambanks b) Install in-stream structures
c) Stabilize all areas of disturbance with matting, seed, and
livestakes.
5) Plan all riparian areas (entire project length) with native shrub
and tree species (see Table on Sheet 1).
