b. Category I, II,and III wetlands that score four or more points for habitat shall have the following buffers: Habitat 4 5 6 7 8 9 Points Buffer Width 7-5 105 135 465 195 225 c. Category IV wetlands that score three or four points for habitat shall have a minimum buffer width of thirty five feet. d. Category IV wetlands that score five or more points for habitat shall have a minimum buffer width of forty four feet. a. For wetlands that score moderate or high for habitat (five points or more for the habitat functions),the following criteria must be met: ai. When feasible, a relatively undisturbed vegetated corridor at least one hundred feet wide must be protected between the wetland and any nearby priority habitat. Presence or absence of a nearby habitat must be confirmed by a qualified biologist. If there is a presence of a nearby priority habitat and if the wetland has a habitat function score of six or more, a 100-foot wide relatively undisturbed,vegetated corridor must be provided between the wetland and other priority habitats if there is a corridor available to provide. If a corridor is available and is not set aside into an easement or tract,the buffers listed in table 37.2 apply.-other priority habitats as defined by the Washington State Department of Fish and Wildlife ("relatively undisturbed" is defined in question corridors have at least thirty percent cover of shrubs or forest. Priority habitats include: (A) Wetlands; (B) Riparian zones; (C) Marine/estuarine shorelines; (D) Urban natural open space. The corridor must be protected for the entire distance between the wetland and the priority habitat by some type of legal protection such as a conservation easement. ii. Measures to minimize the impacts of different land uses on wetlands, such as the examples summarized in Table 37.1, are applied. b. For wetlands that score less than three or four points for habitat, m asures to minimize the impacts of different land uses on wetlands, such as the examples summarized in Table 37.1, must be applied. User instructions: Use the following two tables to determine wetland buffers. Table 37.2 includes the standard buffers without utilizing the general mitigation measures described below. The reduced buffers in Table 37.3 apply to projects when the applicant elects to incorporate all general mitigation measures. If priority habitat is not present, use Table 37.3.
