i 3. Prior to Issuance of construction permits, a wetland mitigation plan shall be submitted to the Planning Department for approval. To be approved, plan must meet the standards contained in the zoning ordinance, particularly Section 37.110(D)—Title 19, as well as addressing the following: a. Whenever feasible, if wetland plant species are not Invasive, they should be removed prior to construction and placed aside in a shady damp location, such as under wet burlap sacks. Following construction, they should be replaced in the wetland area. b. Revegetation: At a minimum,erosion control revegetation is required in all cleared areas and should include herbaceous ground cover that does not interfere with establishment of native vegetation. If long-term revegetation is required, It should be accomplished during the next most favorable time of year for the particular vegetation to ensure the highest level of success. (Note: if revegetation does not occur immediately following recontouring of the site, adequate erosion control measures must be taken.) Native species compatible with preconstruclion vegetation patterns shall be used for revegetation. Degraded emergent sites, such as Reed canary grass fields, shall be replanted with species that are representative of a higher quality emergent, scrub-shrub or forested wetland. If revegetation is required,monitoring should occur once a year for a minimum of two years. c. All mitigation plans shall include the provision of adequate topsoils in areas where plantings will occur. d. Identify any vegetation that is proposed to be removed from the wetlands and/or their buffers and provide rationale for removal(e.g. hazard tree or invasive species). e. All plantings in environmentally sensitive areas and their buffers shall be native species and hybrid natives, Including landscaping required by Chapter 35 of the Zoning Code (perimeter landscaping, landscaping of the parking lot,and interior landscaping). I. Plants with noted habitat or food value for wildlife should be selected wherever possible. Invasive species shall not be planted. A list of native recommended species is Included In Appendix 3.4.6 of the SW Everett/Paine Field Subarea Plan EIS. g. Where native, hybrid natives and/or drought-tolerant species are planted, permanent irrigation systems shall not be required. Temporary irrigation must be provided for two years after planting. h. Plantings In environmentally sensitive areas and their buffers must be designed to simulate Pacific NW native plant communities in terms of composition,cover-abundance, and structure. All mitigation plans shall Include herbs In the planting plan. Diversity of environmentally sensitive area buffer habitat must also be ensured through the planting of later successional forested stages of vegetation (e.g.Western red cedar, Douglas fir, and Western hemlock)where needed and appropriate. I. The provision of thin-stemmed emergents in the northwest portion of wetlands for amphibian breeding habitat must be considered when designing wetland mitigation. j. The provision of large woody debris must be considered when designing mitigation for Impacts to environmentally sensitive areas and their buffers. Sufficient shrub or woody debris cover must be maintained and planted In and adjacent to environmentally sensitive areas to conceal nests from terrestrial predators and thereby insure the survival of ground nesting bird species. In addition, to minimize entrance of predators and humans
