Task 3: List #1 approach to MR #5 compliance <br />0 You are required to use the first applicable BMP that is considered feasible in each <br />category (lawn, landscape, and hard surfaces) below. Mark whether the BMP is feasible or <br />infeasible. If you selected infeasible, cite the reasons for infeasibility (see Worksheet 2) <br />and or a professional, site specific reference to supporting documentation (such as a <br />geotechnical report). <br />List #1: On -Site Stormwater Management BMPs for MR #1-5 Projects <br />Category <br />Feasible <br />Infeasible If infeasible provide justification <br />BMP T5.13: <br />Post -Construction Soil Quality <br />and Depth <br />Feasible <br />Infeasible If infeasible provide justification <br />BMP T5.10A: <br />Downspout Full Infiltration* <br />I <br />✓ <br />*Soils report required for this BMP <br />or <br />No native vegelauon.;nsumdenl space for <br />BMP 5.30: <br />Full Dispersion <br />—i <br />setbacks. flowpalh <br />BMP T5.14A: <br />Rain Gardens* <br />L <br />✓ <br />*Soils report required for this BMP <br />or <br />BMPfl.30: <br />Bioretention Cells, Swales, <br />✓I <br />Insufficient space for setbacks <br />and Planter Boxes <br />BMPT5.10B: <br />Downspout Dispersion <br />✓ <br />Insufficient space for flow paths <br />Systems <br />BMP T5.10C: <br />Perforated Stub -out <br />✓ <br />fompose solid connection, due to fack of;nelvauon <br />Connections <br />etback <br />zip t <br />Feasible <br />Infeasible <br />If infeasible provide justification <br />BMP T.530: <br />Full Dispersion <br />— <br />✓I <br />No native vegetation <br />BMP T5.15: <br />Permeable Pavements* <br />✓I <br />*Soils report required for this BMP <br />or <br />BMP T5.14A: <br />Rain Gardens* <br />— <br />✓ <br />Insufficient space for setbacks <br />or <br />BMPT7.30: <br />Bioretention Cells, Swales, <br />_ <br />✓ <br />Insufficient area within setback <br />and Planter Boxess <br />BMPT5.12: <br />Sheet Flow Dispersion <br />Insufficient space adjacent to driveway <br />or <br />BMP T5.11: <br />Concentrated Flow Dispersion <br />✓ <br />Propose connection to ditch <br />* If you selected BMP T5.10A Downspout Full Infiltration submit 1 and 3 below. <br />* If you selected BMPT5.15 Permeable Pavement or T5.14A Rain Gardens in Lisi on -site soils information for sizing <br />or infeasibility determination is required from 1 through 4 below. <br />Submit the following information to Permit Services with this report: <br />1) A USDA Custom Soil Report from websoilsurvev.sc.eaov.usda.gov. <br />2) Small-scale Pilot Infiltration Tests (PIT) per SWMMWW specifications <br />3) USDA Soil Type(s)=___ <br />4) Measured Infiltration Rate = ini (from PIT) <br />City of Everett Public Works <br />Small Project Stormwater Site Plan Report -Dec 2019 18 <br />
