accepted methodologies and include information as required by the planning director's administrative guidelines, and shall: 1. Include a baseline study that quantifies the existing wetland and buffer functions,functions that will 2. Specify how functions will be preserved or replaced; 3. Specify how impacts will be avoided, minimized or compensated for; 1. 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; b. 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 planning director sign off to indicate that construction has been completed as planned.A separate performance assurance device shall be required for maintenance, monitoring, and contingency.This sign off that maintenance and monitoring have been completed per the plan, and the mitigation meets performance goals. E. Construction Plans. Construction plans necessary to implement requirements of the detailed mitigation plan shall be provided prior to issuance of construction permits. Plans shall include the proposed hydrologic regimes for compensatory mitigation areas; grading and excavation details, erosion and sediment control m asures; a planting plan specifying plant species, quantities, location, size, spacing, density, proper placement,fertilization standards, and provisions for temporary irrigation systems. required by Section 19.37.220 of this chapter. Section 16. Ordinance 2909-06, as amended, (Zoning Code, Critical Areas), is hereby amended by the addition of the following section,to be codified as EMC 19.37.125 (Wetland Mitigation Banks): 19.37.125 Wetland Mitigation Banks A. Wetland mitigation banks are sites where wetlands are restored, created, enhanced, or in exceptional circumstances, preserved, expressly for the purpose of providing compensatory mitigation in advance of authorized impacts to similar resources. Banks typically involve the consolidation of many small wetland mitigation projects into a larger, potentially more ecologically EMC Title 19.37 (Critical Areas) Page 42
