Exhibit B <br />ORDINANCE Exhibit A - Page 63 of 66 <br />4. Other actions necessary to enhance the viability of the riparian corridor for the benefit of <br />wildlife habitat. <br />H. Functionally Disconnected Buffer Areas. Buffers may exclude areas that are functionally and <br />effectively disconnected from a stream or lake by an existing public or private road or legally established <br />development, as determined by the planning director. Functionally and effectively disconnected means <br />that the road or other significant development blocks the protective measures provided by a buffer. <br />Significant developments shall include built public infrastructure such as roads and railroads, and private <br />developments such as homes or commercial structures. Examples of minor developments that do not <br />fully block buffer functions include trails, minor accessory structures, paths, and driveways serving a <br />single residence. The planning director shall evaluate whether the interruption will affect the entirety of <br />the buffer. Individual structures may not fully interrupt buffer function. In such cases, the allowable <br />buffer exclusion should be limited in scope to just the portion of the buffer that is affected. Where <br />questions exist regarding whether a development functionally disconnects the buffer, or the extent of <br />that impact, the planning director may require a critical area report to analyze and document the buffer <br />functionality. <br />19.37.540 FISH AND WILDLIFE HABITAT CONSERVATION AREAS – BUFFER WIDTH AVERAGING <br />FOR LAKES AND STREAMS <br />The city may allow buffer width averaging for lakes and streams when all of the following are met: <br />A. No feasible alternatives to the site design could be accomplished without buffer averaging; <br />B. The total area on the lot contained within the buffer after averaging is not less than the area required <br />within the buffer without averaging; <br />C. Averaging will not reduce the functions and values of the critical area or buffer as demonstrated by a <br />critical area report from a qualified professional; and <br />D. The adjusted minimum buffer width shall not be less than seventy-five percent of the required buffer <br />width at any point. <br />19.37.550 FISH AND WILDLIFE HABITAT CONSERVATION AREAS – STREAM ALTERATION <br />THRESHOLDS AND COMPENSATORY MITIGATION <br />A. Stream Preservation/Alteration Thresholds. <br />1. Type S Streams. All Type S streams shall be regulated by the city of Everett shoreline master <br />program. <br />2. Type F Streams. All Type F streams shall be preserved. The city may only allow alteration of <br />Type F streams under the following circumstances: <br />a. Where alteration is allowed pursuant to EMC 19.37.050; <br />b. Stream Crossings. Stream crossings are regulated by the Washington State <br />Department of Fish and Wildlife (WDFW). Stream crossings shall only be permitted as <br />provided by EMC 19.37.050 or to provide access to a lot or a substantial portion of a lot <br />when no other feasible means of access exists. Use of common access points shall be <br />required for abutting lots which have no other feasible means of access. Alteration for
