Exhibit B <br />ORDINANCE Exhibit A - Page 23 of 55 <br />5. Describe the future vegetation community types for monitoring years, including dominant <br />vegetation expected. Plants shall be native species, commercially available or available from <br />local sources, high in food and cover value for fish and wildlife, and mostly perennial; <br />6. Specify when mitigation will occur relative to project construction and to the requirements <br />of permits issued by other agencies; <br />7. Include measurable criteria for evaluating whether the performance goals of the mitigation <br />proposal have been met, and include provisions for maintenance and monitoring the mitigated <br />area on a long-term basis to determine whether the plan was successful; <br />8. Include a contingency plan specifying what corrective actions will be taken to achieve <br />performance goals should the mitigation not be successful; and <br />9. Include provisions for an assurance device as provided by Chapter 19.40 to ensure that work <br />is completed in accordance with the mitigation plan, that maintenance and monitoring occur on <br />a regular basis, and that restoration or rehabilitation is performed in accordance with the <br />contingency plan if mitigation failure results within five years of implementation. The <br />construction performance guarantees shall not be released until the applicant’s qualified <br />professional and the planning director sign off to indicate that construction has been completed <br />as planned. A separate performance assurance device shall be required for maintenance, <br />monitoring, and contingency. This guarantee shall not be released until the applicant’s qualified <br />professional and the planning director sign off that maintenance and monitoring have been <br />completed per the plan, and the mitigation meets performance goals. <br />B. Stream, lake and buffer impact mitigation plans shall: <br />1. 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 />2. Specify how functions will be replaced; <br />3. Specify when mitigation will occur relative to project construction and to the requirements <br />of permits issued by other agencies; <br />4. 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 />5. Include provisions for maintaining and monitoring the mitigated area on a long-term basis to <br />determine whether the plan was successful; <br />6. Include a contingency plan specifying what corrective actions will be taken should the <br />mitigation not be successful; and <br />7. 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
