Task 3: List #1 approach to MR #5 compliance <br /> 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 1 - Lawn and Landscaped Areas <br /> Feasible Infeasible If infeasible provide justification <br /> BMP T5.13: Post-Construction Soil Quality <br /> and Depth ❑ <br /> Category 2- Roofs <br /> Feasible Infeasible If infeasible provide justification <br /> BMP T5.10A: Downspout Full Infiltration* ❑ 7 *Soils report required for this BMP <br /> or <br /> BMP 5.30: Full Dispersion ❑ j STEEP SLOPE, LACK OF AREA <br /> BMP T5.14A: Rain Gardens* ❑ *Soils report required for this BMP <br /> or <br /> BMPT7.30: Bioretention Cells,Swales, ❑ GEOTECH RECOMMENDS NO <br /> and Planter Boxes STEEP SLOPE, POOR SOIL <br /> BMP T5.10B: Downspout Dispersion ❑ GEOTECH RECOMMENDS <br /> Systems AGAINST USING DISPERSION <br /> BMP T5.10C: Perforated Stub-out POOR SOIL, STEEP SLOPE <br /> Connections GEOTECH RECOMMENDS NO <br /> Category 3- Other Hard Surfaces <br /> Feasible Infeasible If infeasible provide justification <br /> BMP T.530: Full Dispersion ❑ LACK OF FLOWPATH <br /> BMP T5.15: Permeable Pavements* ❑ *Soils report required for this BMP <br /> or GEOTECH RECOMMENDS <br /> BMP T5.14A: Rain Gardens* ❑ AGAINST USING INFILTRATION <br /> or <br /> BMPT7.30: Bioretention Cells,Swales, ❑ <br /> and Planter Boxes <br /> BMP T5.12: Sheet Flow Dispersion ❑ ® GEOTECH RECOMMENDS <br /> or AGAINST USING DISPERSION <br /> BMP T5.11: Concentrated Flow Dispersion ❑ <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 List#1, 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 websoilsurvey.sc.egov.usda.gov <br /> 2) Small-scale Pilot Infiltration Tests(PIT)per SWMMWW specifications <br /> 3) USDA Soil Type(s)= <br /> 4) Measured Infiltration Rate=__ in/hr(from PIT) <br /> City of Everett Public Works <br /> Small Project Storm water Site Plan Report-Dec 2019 18 <br />
