Exhibit B ORDINANCE Exhibit A - Page 31 of 55 19.37.110 STANDARD WETLAND BUFFER WIDTH REQUIREMENTS. A. Standard Buffer Width. 1. The following buffer widths listed in Tables 37.2 and 37.3 apply to all wetlands within the city of Everett. Buffer widths have been established in accordance with the best available science. Buffers are based on the category of wetland and the habitat score as determined by a qualified wetland professional using the Washington State Wetland Rating System for Western Washington: 2014 Update (Ecology Publication No. 14-06029, or as revised and approved by Ecology). 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 one-hundred-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. 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.
