withdrawn from the well. Will water be discharged to groundwater? Give general <br /> description, purpose, and approximate quantities if known. <br /> It will not. <br /> 2) Describe waste material that will be discharged into the ground from septic tanks or <br /> other sources, if any (for example: Domestic sewage; industrial, containing the <br /> following chemicals. . . ; agricultural; etc.). Describe the general size of the system, the <br /> number of such systems, the number of houses to be served (if applicable), or the <br /> number of animals or humans the system(s) are expected to serve. <br /> No waste material would be discharged from septic tanks of other sources. <br /> c. Water runoff(including stormwater): <br /> 1) Describe the source of runoff(including storm water) and method of collection <br /> and disposal, if any (include quantities, if known). Where will this water flow? <br /> Will this water flow into other waters? If so, describe. <br /> At time of development the proposed impervious surface water run off shall be collected via <br /> conveyance systems and conveyed to a detention system. The stormwater would then be <br /> filtrated in the storm filter and discharged on the western portion of the site. The sizes and <br /> quantities shall be determined with the final construction process. please refer to the <br /> attached grading and drainage plan <br /> 2) Could waste materials enter ground or surface waters? If so, generally describe. <br /> Oil, grease, and other pollutants from the additional paved areas could potentially enter the <br /> ground or downstream surface waters through surface water runoff. construction of the <br /> detention, control structures and water quality features of the detailed drainage plan would <br /> provide adequate downstream protection <br /> 3) Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If <br /> so, describe. <br /> No. <br /> d. Proposed measures to reduce or control surface, ground, and runoff water, and drainage <br /> pattern impacts, if any: <br /> Temporary and permanent drainage facilities meeting county and state standards would be <br /> employed to control surface runoff during construction and after development. Detention and <br /> controlled release will limit erosion impacts. primary treatment in the form of storage and <br /> filtration will settle sediments. The location and design of permanent storm drainage facilities <br /> would match existing drainage patterns and runoff rates. <br /> 4. Plants <br /> a. Check the types of vegetation found on the site: <br /> deciduous tree: alder maple, aspen, other <br /> evergreen tree: cedar, pine, other <br /> SEPA Environmental checklist(WAC 197-11-960) July 2016 Page 5 of 12 <br />
