• <br />• <br />COMPLETE IF USING INFILTRATION (2A or 213) TO MEET FLOW <br />CONTROL REQUIREMENT <br />Determine whether infiltration has been pre -determined to be infeasible for any portion of your <br />project site. <br />■ Review the infiltration infeasibility mapping tool available on "Map Everett' <br />. everettwa.gov/mapeverett. <br />■ On the mappingtool, select"Geotechnical/Infiltration Infeasibility Area" and the <br />applicable "Property" layers from the Layer List. <br />■ Zoom into your project site and print the resulting map to show the project site <br />boundaries and the infiltration infeasibility mapping results. <br />■ Areas mapped as red have been pre -determined to be infeasible for infiltration. <br />■ Areas mapped as green are potentially feasible for infiltration and must be <br />assessed further for infiltration feasibility, as discussed further below. <br />■ Attach a printed copy of the map clearly showing your project site boundary and the <br />infiltration infeasibility mapping results. <br />* If you selected Downspout Full Infiltration (2A), submit I and 2 below. <br />If you selected Rain Garden/Bioretention (2113), on -site soils information for sizing is <br />required from I through 3 below. <br />Submit the following information to Permit Services with this report: <br />. A USDA Custom Soil Report from https://websoilsurvey.sc.egov.usda.gov <br />2. USDA Soil Type(s)= <br />3. Measured Infiltration Rate = in/hr, measured at BMP location on -site. Use Rain Garden <br />Handbook methodology for infiltration test. <br />City of Everett Public Works <br />Small Project Stormwater Site Plan Report for Projects in 20 <br />the Combined Sewer Area-April2021 <br />
