Exhibit B <br />ORDINANCE Exhibit A - Page 60 of 66 <br />conditions; replanting with native vegetation; potential of habitat enhancement <br />(i.e., fish passage barrier removal); best management practices, etc.; <br />(2) Include a description of proposed monitoring of the species, its habitat, and <br />mitigation effectiveness, for a minimum of five years. <br />d. The habitat management plan shall identify the specific habitat objectives the <br />habitat management plan is designed to achieve and include recommendations <br />regarding all actions taken which are necessary to avoid reducing the likelihood that the <br />species will maintain and reproduce over the long term, and/or actions to maintain or <br />enhance the significant features present <br /> F. Stream, Lake, and Buffer Mitigation Plans. Stream, lake and buffer mitigation plans shall: <br />a. Include a baseline study that quantifies the existing functions of the system, functions that <br />will be lost, and the stream and buffer functions after mitigation; <br />b. Specify how functions will be replaced; <br />c. Specify when mitigation will occur relative to project construction and to the requirements of <br />permits issued by other agencies; <br />d. Where buffer enhancement is proposed, include an analysis of the ability of the buffer to <br />protect water quality, as outlined in the Update on Wetland Buffers: The State of the Science, <br />Final Report, October 2013, Washington State Department of Ecology Publication No. 13-06-11, <br />or as amended; <br />e. Include provisions for maintaining and monitoring the mitigated area on a long-term basis to <br />determine whether the plan was successful; <br />f. Include a contingency plan specifying what corrective actions will be taken should the <br />mitigation not be successful; and <br />g. Include provisions for an assurance device as provided by Chapter 19.40 EMC to ensure that <br />work is completed in accordance with the mitigation plan and that restoration or rehabilitation <br />is performed in accordance with the contingency plan if mitigation failure results within five <br />years of implementation. <br />19.37.530 FISH AND WILDLIFE HABITAT CONSERVATION AREAS – STREAM AND LAKE BUFFER <br />REQUIREMENTS <br />A. Stream Buffer Width. It is the goal of this chapter to preserve streams and their buffers in a natural <br />condition to the maximum extent possible. <br />1. Buffers shall be measured from the ordinary high water mark as surveyed in the field. In <br />braided channels and alluvial fans, the ordinary high water mark shall be determined so as to <br />include the entire stream feature. <br />2. Stream buffers shall exclude functionally disconnected areas legally altered as described in <br />EMC 19.37.530(H).
