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. 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. 5. 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. 6. The provision of thin-stemmed emergents in the northwest portion of wetlands for amphibian breeding habitat must be considered when designing wetland mitigation. 8. 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. For example, downed logs which provide quality nesting habitat for winter wrens should be maintained and fast growing shrubs (i.e. red-osier dogwood) should be planted to provide added concealment of ground nests from predators. In addition, to minimize entrance of predators and humans into wetlands, "barrier" species such as native roses (Rosa sp.) could be planted in buffers. 12. Only limited clearing of undeveloped sites for marketing purposes will be permitted prior to application for development permits. Clearing shall be primarily for access roads. Clearing must be limited to areas outside of environmentally sensitive areas, and buffers for these areas shall be doubled until such time as a development is proposed on the site. Clearing is not permitted in any area designated as buffer and/or wildlife corridors, and must not occur within 300 feet of a residential area. Clearing should not remove coniferous trees. Erosion control measures must be installed to prevent sediment and erosion impacts to adjacent properties and environmentally sensitive areas and their buffers. A clearing plan must be submitted to the City Planning and Engineering and Public Services Departments for their approval, and temporary detention ponds must be provided for any clearing as required by the Public Works Department. 4.3.4 Mitigating Impacts of Development on Wetlands 2. Wetlands must be retained and buffers must be provided per the requirements of Chapter 37, or mitigation must occur. Where the applicant proposes alteration of the wetland or buffer, additional studies must be completed and the alterations must be approved by the Planning Director. 4. Development of a project site must not result in significant adverse effects to the hydrology of wetlands on or adjacent to the site. Prior to application for Public Works permits and plan review by the Engineering and Public Services Department, a characterization of the hydrology of the wetland(s) on or adjacent to this project that may be affected by the
