WAC 222-24-035
Landing location and construction. *(1)
Landing location:
Locate landings to prevent potential or actual damage to
public resources. Avoid excessive excavation and filling. Landings shall not be located within natural drainage channels,
channel migration zones, RMZ core and inner zones, Type Np RMZs,
sensitive sites, equipment limitation zones, and Type A or B
Wetlands or their wetland management zones. Minimize placement
and size of landings within forested wetlands. (See WAC 222-24-015, Construction in wetlands.)
(2) Landing construction.
(a) Landings requiring sidecast or fill shall be no larger
than reasonably necessary for safe operation of the equipment
expected to be used.
*(b) Where the slopes exceed 60 percent, fill material used
in construction of landings shall be free from loose stumps and
excessive accumulations of slash and shall be mechanically
compacted where necessary and practical in layers by tractor to
prevent soil erosion and mass soil movement. Chemical compacting
agents may be used in accordance with WAC 222-38-020.
*(c) Truck roads, skid trails, and fire trails shall be
outsloped or cross drained uphill of landings and the water
diverted onto the forest floor away from the toe of any landing
fill.
*(d) Landings shall be sloped to minimize accumulation of
water on the landing.
*(e) Excavation material shall not be sidecast where there
is high potential for material to enter wetland management zones
or within the bankfull width of any stream or the 100-year flood
level of any typed water.
*(f) All spoils shall be located outside of Type A and Type
B Wetlands and their wetland management zones. Spoils shall not
be located within the boundaries of forested wetlands without
written approval of the department and unless a less
environmentally damaging location is unavailable. No spoil area
greater than 0.5 acre in size shall be allowed within wetlands.
(See WAC 222-24-015, Construction in wetlands.)
*(3) Temporary landings.
(a) A temporary landing is intended for use during the life
of an approved application/notification.
(b) It must be constructed to facilitate abandonment when
the intended use is complete or upon seasonal shutdown, whichever
is sooner.
(c) It must be designed to provide the same level of
protection for public resources as provided by the rules during
the length of its intended use.
(d) Temporary landings must be identified on the forest
practices application or notification, along with an abandonment
date.
(e) Temporary landings must be abandoned to the
specifications approved by the department by the date specified
on the approved forest practices application.
