each tree left as a snag, one coniferous tree must be planted. The arborist must submit a tree removal and replacement plan to the Planning Department and mark in the field all trees to be removed. The Planning Department must approve the tree removal and replacement plan prior to any activity in the environmentally sensitive area. Large woody debris should be retained where it would not create a hazard, such as causing flooding due to alteration of the natural hydrology of a stream system. (SEPA Plant and Animal Policies) 4. A variety of native species can be planted to increase local diversity and provide attractive wildlife habitat while countering erosion. The use of native plants can also improve water quality by minimizing the use of fertilizers, herbicides, and pesticides. Water use efficiency is another advantage of landscaping with native plants. Reduced irrigation means reduced likelihood of erosion, siltation, and landsliding resulting from the development, reduced impacts to local hydrology, reduced maintenance costs, and enhanced water availability for other consumptive uses. All plantings in environmentally sensitive areas and their buffers and in transition areas in SW Everett 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). The City has a goal that 75% of new landscaping in the Subarea be native, hybrid natives, or drought-tolerant. Landscape plans should show an attempt to reach this goal unless landscaping with these species will not meet the objective of the proposal (e.g., golf driving range, ball fields, etc.). 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. (SEPA Plant and Animal, Water and Public Services Policies) 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. (SEPA Plant and Animal Policies) 6. The provision of thin-stemmed emergents in the northwest portion of wetlands for amphibian breeding habitat must be considered when designing wetland mitigation. (SEPA Plant and Animal Policies) 7. Exotic invasive species must be controlled. English ivy (Hedera helix) shall not be planted in the Subarea. Properties must be maintained to eliminate Scot's broom and other invasive species. (SEPA Plant and Animal and Land and Shoreline Use Policies) 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 21
