area will be isolated and fish will be excluded and removed prior to dewatering.Fish exclusion <br /> and dewatering will follow approved protocol in accordance with the WDFW HPA permit. Once <br /> the removal of the culvert and fill are complete and the channel has been constructed,flow will <br /> be redirected back into the stream channel and exclusion systems will be removed.. <br /> 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. <br /> fhelol <br /> According to Snohomish County Interactive map viewer and the FEMA floodplain map for the <br /> project area,the project does not lie within the 100-year floodplain. <br /> 6) Does the proposal involve any discharges of waste materials to surface waters? If so, <br /> describe the type of waste and anticipated volume of discharge.Jhelpl <br /> There will be no discharge of waste materials to surface waters as a result of active construction. <br /> b. Ground Water: <br /> 1)Will groundwater be withdrawn from a well for drinking water or other purposes? If so, <br /> give a general description of the well, proposed uses and approximate quantities <br /> withdrawn from the well. Will water be discharged to groundwater? Give general <br /> description, purpose, and approximate quantities if known. Jhelpl <br /> Groundwater will not be withdrawn. Water will not be discharged into the groundwater system. <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. Jhelpl <br /> No waste material will be discharged into the ground. <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. f help' <br /> Runoff will only occur in the event of precipitation during active construction.This stormwater <br /> will likely flow into Woods Lake Creek.Typical stormwater BMPs will be utilized during <br /> construction to minimize potential impacts. <br /> 2) Could waste materials enter ground or surface waters? If so, generally describe. Jhelpj <br /> Waste materials will be controlled through BMPs to contain any materials that may have the <br /> potential to enter Woods Lake Creek. In addition, a SWPPP will be prepared for the project. <br /> 3) Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If <br /> so, describe. fhelpl <br /> SEPA Environmental checklist(WAC 197-11.960) July 2016 Page 7 of 18 <br />
