of
The seeding rate will bl cut in half if drilled.
3.
Seed mix species percentages will be determined prior to installation.
4.
The relocated Bull Sees: will be field adjusted to minimize disturbance

Live stakes /plugs and /Ir nursery stock shall be installed to equal
®_
approximately one plant per four sq. ft. Material will be installed in a

random fashion to crede a natural appearance rather than strictly one
plant 4' on center.
6.
Portions of the existing Bull Seep not to be disturbed will not receive
P
additional plant moterics. The Plant Material List refers only to those
portions of the Bull Setp that are to be modified from existing
'..N
vegetated condition.
7.
If plant material is collected from on –site sources (Live Stakes /Plugs),
it shall be planted withn 48 hours of collection. Plant material shall
be collected during the dormant period if possible. If on –site sources
ss �v
are not available or apropriate, live plants will be obtained from a
N
reputable supplier.
8.
Channel side slopes oletg the relocated Bull Seep will vary and will be
`
field adjusted as approriate.
9.
Live stock or stakes aid seed species may need to be adjusted in the
field at the time of irolementation to reflect species composition of
on –site sources, or suplier availability.
10.
There will be no woody material planted within 50 feet of the reservoir
liner to prevent roots tom damaging the liner integrity.
11.
Typical sections schemitically show plant locations. Actual plant
N
locations will correspon! to actual field conditions. Shrub and tree
planting locations shout be approved by the Owners Representative
prior to planting. Specks will be installed in hydrologically appropriate
zones within areas spaified above.
