Exhibit B <br />ORDINANCE Exhibit A - Page 33 of 66 <br />1. Where geologically hazardous slopes are located in a stream, wetland, and/or a fish and <br />wildlife habitat conservation area or their required buffers, alteration of the slopes is not <br />permitted, except as allowed under EMC 19.37.050. The required buffer for such slopes shall be <br />determined through the site-specific geological assessment, but in no case shall be less than <br />twenty-five feet from the top of slopes of twenty-five percent and greater. <br />2. Any proposed alteration that would result in the creation of or which would increase or <br />exacerbate existing geological hazards, or which would result in substantial unmitigated <br />geological hazards either on site or off site, shall be prohibited. <br />ARTICLE III. WETLANDS <br />19.37.300 WETLANDS - DESCRIPTION AND PURPOSE <br />A. Wetlands are defined using the Washington State definition of wetlands established under RCW <br />36.70A.030(48) and as defined in EMC 19.04.110. <br />B. The purpose of this chapter’s wetland regulations are to: <br />1. Recognize and protect the beneficial functions performed by wetlands, including those <br />physical, biological, chemical, and geologic interactions within wetlands and the surrounding <br />landscape, including buffers. These functions are often grouped into three main categories – <br />water quality improvement functions, hydrologic functions, and habitat functions and may <br />include but are not limited to: <br />a. The uptake, removal, transformation, and cycling of nutrients, sediment, and <br />toxicants; <br />b. Floodflow alteration, surface water storage, reduction of peak flows, groundwater <br />recharge, decreasing downstream erosion, and energy dissipation of flows; <br />c. Supporting food webs and providing several habitat niches and features for wildlife <br />breeding, nesting, and rearing, and providing thermal refugia. <br />2. Regulate land use to avoid adverse effects on wetlands and maintain the functions and values <br />and of wetlands throughout the city. <br />3. Establish review procedures for development proposals in and adjacent to wetlands. <br />a. Compliance with the provisions of this chapter does not necessarily constitute <br />compliance with other federal, state, and local regulations and permit requirements. <br />Applicants are responsible for complying with these requirements. <br />19.37.310 WETLANDS – DELINEATION, MAPPING, AND RATING <br />A. Wetland Delineation. Identification of wetlands and delineation of their boundaries pursuant to this <br />chapter shall be done in accordance with the approved federal wetland delineation manual and <br />applicable regional supplements (Regional Supplement to the Corps of Engineers Wetland Delineation <br />Manual: Western Mountains, Valleys, and Coast Region (Version 2.0). All areas within the city meeting <br />the wetland designation criteria in that procedure are hereby designated critical areas and are subject to
