Permanent slopes steeper than 25% shall be designed by a professional civil or geotechnical engineer. The design should present appropriate erosion control measures which may include: hydroseeding, erosion control blankets, rip -rap, jute matting, and visqueen. (SEPA Earth and Water Policies) 6. Grading/filling on -site shall not adversely iffect adjoining sites. (SEPA Earth and Water Policies) Section 4: SURFACE/GROUNDWATER, PLANTS AND ANIMALS 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) The landscaping along the northern side of the parking lot is in au area designated environmentally sensitive. All landscaping in that area shall be native species. Any irrigation in that area must be approved by the geotechnical engineer. 8. Exotic invasive species must be controlled. English ivy (Nedera 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) 9. All storm drains must he stenciled with language similar to the following: "Dump No Waste, Drains to Stream."
