Ordinance 3676-19 - Laserfiche WebLink

measures serve to minimize or compensate for project effects on the species under review. The following items should be addressed: i. Provide specific recommendations,as appropriate,to reduce or eliminate the adverse effects of the proposed activity. Potential measures include:timing restrictions for all or some of the activities;clearing limitations;avoidance of specific areas;special construction techniques; HMP conditions; replanting with native vegetation; potential of habitat enhancement(i.e.,fish passage barrier removal); best management practices,etc.; ii. Include a description of proposed monitoring of the species, its habitat, and mitigation effectiveness. d. The HMP shall identify the specific habitat objectives the HMP is designed to achieve and include recommendations regarding all actions taken which are necessary to avoid reducing the likelihood that the species will maintain and reproduce over the long term,and/or actions to maintain or enhance the significant features present. Section 8. Ordinance 2909-06, as amended, (Zoning Code, Critical Areas), is hereby amended by the addition of the following section,to be codified as EMC 19.37.075 (Wetlands, streams and lakes— mitigation plans—required content): 19.37.075 Wetlands,streams and lakes -mitigation plans—required content A. Wetland and buffer impact mitigation plans shall: 1. Include a baseline study that quantifies the existing wetland and buffer functions,functions that will be lost,and the functions after mitigation.This could involve assessing functions using Calculating Credits and Debits for Compensatory Mitigation in Wetlands of Western Washington: Final Report, March 2012.Washington State Department of Ecology Publication No. 10-06-011, or as amended; 2. Specify how functions will be preserved or replaced; 3. Specify how impacts will be avoided, minimized or compensated for; 4. Assess the potential changes in wetland hydroperiod from the proposed project and identify how the project design will mitigate adverse impacts to the wetland hydroperiod; 5. Describe the future vegetation community types for monitoring years, including dominant vegetation expected. Plants shall be native species,commercially available or available from local sources, high in food and cover value for fish and wildlife,and mostly perennial; 6. Specify when mitigation will occur relative to project construction and to the requirements of permits issued by other agencies; 7. Include measurable criteria for evaluating whether the performance goals of the mitigation proposal have been met, and include provisions for maintenance and monitoring the mitigated area on a long-term basis to determine whether the plan was successful; 8. Include a contingency plan specifying what corrective actions will be taken to achieve performance goals should the mitigation not be successful;and 9. Include provisions for an assurance device as provided by Chapter 19.40 of this title to ensure that work is completed in accordance with the mitigation plan,that maintenance and monitoring occurs on a regular basis,and that restoration or rehabilitation is performed in accordance with the contingency plan if mitigation failure results within five years of implementation.The construction performance guarantees shall not be released until the applicant's qualified professional and the planning director sign off to indicate that construction has been completed as planned.A separate performance assurance device shall be required for maintenance, EMC Title 19.37 (Critical Areas) Page 21
