The project is not likely to allow significant adverse waste materials to enter ground or surface <br /> waters. New catch basins will collect on-site runoff and direct it to on-site treatment systems <br /> prior to releasing it off-site. Any polluted water on-site will be treated before it is released into <br /> the existing downstream system. <br /> 3) Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If <br /> so, describe. Jhelpl <br /> No <br /> d. Proposed measures to reduce or control surface, ground, and runoff water, and drainage <br /> pattern impacts, if any: (help' <br /> To address potential surface,ground,runoff water impacts or drainage pattern impacts,the <br /> project will use a City of Everett/DOE approved stormwater water treatment system that <br /> includes a modular wetland,filterra water treatment system,and an oil-water separator. An <br /> underground detention vault will be used to satisfy on-site flow control requirements. The <br /> project's water quality and flow controls will meet or exceed all current City of Everett/DOE <br /> stormwater manual standards. <br /> 4. Plants 'help] <br /> a.

What kind and amount of vegetation will be removed or altered?Jhelp' <br /> The site is vacant.Primarily field grasses will be removed for the project and some landscape <br /> plants will be removed near the right of way for street improvements. Trees along the south side <br /> of the site will be removed and replaced with landscaping. <br /> c. List threatened and endangered species known to be on or near the site. 'help' <br /> None <br /> d. Proposed landscaping, use of native plants, or other measures to preserve or enhance <br /> vegetation on the site, if any:'help' <br /> The project will provide drought tolerant landscaping and include native plants. <br /> SEPA Environmental checklist(WAC 197-11-960) July 2016 Page 6 of 15 <br />
