(2) The department, in addition to the above requirements, may require other
reasonable measures to further protect the natural river environment, including
the following as are deemed appropriate and necessary:
(a) Upon reaching the natural vegetation strip during clearing operations for
overhead electric transmission line, communication line, and pipeline rights-of-way,
tall-growing tree species may selectively be removed. Shrubs, low-growing tree
species with a mature height of less than 20 feet, and other vegetation shall be left as
natural as possible. Following construction, special measures may be required to
discourage damaging off-road vehicle use, enhance wildlife habitat, or protect
against soil erosion. The department may require that the right-of-way be left in a
rough, ungraded condition and that slash and stumps be scattered over the right-of-way
or made into brush piles, if landowner concurrence is obtained.
(b) A single-span stream crossing shall be used whenever possible, which shall be
consistent with proper vertical clearance of the wires over the waterway and proper
structure height for minimal adverse visual impact. This will result in poles being
placed as far landward of the river banks as possible.
(c) If an underground utility right-of-way crosses the natural vegetation strip,
only minimal brush and tree removal shall
performed during construction.
Following construction, special measures may be required to restore the natural
appearance of the area, stabilize river banks, discourage damaging off-road vehicle
use, or enhance wildlife habitat. If revegetation is required, native plant materials
commonly used in that area, as specified by the department, shall be replanted in
the natural vegetation strip. The department may require that the right-of-way be left in a
rough, ungraded condition and that slash and stumps be scattered over the right-
of-way or made into brush piles, if landowner concurrence is obtained.
(d) Management of trees, shrubs, and other vegetation for maintenance of all rights-of-
way shall be done manually in the natural vegetation strip.However, herbicides may be
applied by hand to stumps of selectively cut trees in the natural vegetation strip,
where establishing and maintaining a low-growing shrub community in this zone will
further the objectives of the act. The department may authorize application of selected
pesticides to control insect or disease infestations.
(e) The time and method of planting recommended vegetation shall be specified by
the department to ensure maximum survival and growth of plant species.
(f) The stream shall be crossed by a method of construction which minimizes
disruption to the streambed. Streams should be crossed at the point and time least
damaging to fishery resources, and generally at right angles. If aerial crossings are
used, they shall be designed
to accommodate recreational use of the river in
addition to protection of the streambanks.
(g) Materials used for bank stabilization following a river crossing shall maintain
and enhance the natural and aesthetic qualities of the natural river area, control
bank erosion, restore fish habitat, and discourage damaging off-road vehicle use.
Specifications regarding stabilization efforts and revegetation shall be consistent with
the goals of maintaining stream width as near as possible to the original width, and to
provide early revegetation of the area involved.
(h) During construction for a new road or bridge, or reconstruction of an existing road
or bridge, strict erosion control measures shall be taken to prevent sediment from
