Section 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.

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.Wash.
