7. Prior to initiation of construction,a biologist or wetland/stream expert must inspect construction fencing along environmentally sensitive areas buffers/construction limits to ensure that fencing is located properly. The biologist/expert should inspect the site occasionally during construction,and shall have authority to impose a stop work order immediately if the biologist/expert determines that work activities violate buffer and setback requirements. (SEPA Plant and Animal,Water,and Land and Shoreline Use Policies) 4.3.2 Mitigating Impacts of Development on Vegetation and Wildlife 1. Where development occurs adjacent to environmentally sensitive areas,an analysis of hazardous trees in the environmentally sensitive area must be completed by a professional arborist. Any trees that are hazardous(i.e., are diseased,damaged or leaning and are likely to fall on development)must be removed prior to issuance of occupancy permits,and preferably,prior to construction of structures on the site. Where they would not create a hazard,the trunks of these trees must be left for snags. For each tree cut,three coniferous trees must be planted unless the Planning Director determines that sufficient natural coniferous revegetation is occurring in the area. However,for 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) 2. 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) 3. 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.
