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 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 ar a on a long term basis to determine whether the plan was successful; S. 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 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, monitoring,and contingency.This guarantee shall not be released until the applicant's qualified professional and the planning director 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 measures; a planting plan specifying plant species, quantities, location, size, spacing, density, proper placement, fertilization standards, and provisions for temporary irrigation systems. F. Protective Covenants and Tracts. Wetlands and their buffers on development sites, including compensatory mitigation ar as, shall be placed within a critical area protective covenant or tract as required by Section 19.37.220 of this chapter. 19.37.115 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 valuable site. Such consolidation encourages greater diversity of habitat and wetland functions. It also helps create more sustainable systems. Banks provide a greater likelihood of success over permittee-responsible mitigation projects, since the banks are up and running before unavoidable damage occurs to a wetland(s) at another site. 1. The city may allow wetland mitigation banking in lieu of other forms of wetland impact mitigation when the mitigation site being used for the credit allowed pursuant to this section is either a Planning Commission Resolution 19-04 Page 45 Critical Areas March 19, 2019
