Task 3: List #1 approach to MR #5 compliance You are required to use the first applicable BMP that is considered feasible in each 0 category (lawn, landscape, and hard surfaces) below. Mark whether the BMP is feasible or infeasible. If you selected infeasible, cite the reasons for infeasibility (see Worksheet 2) and or a professional, site specific reference to supporting documentation (such as a geotechnical report). List #1: On -Site Stormwater Management BMPs for MR #1-5 Projects Feasible Infeasible If infeasible provide justification BMP T5.13: Post -Construction Soil Quality and Depth F_ Feasible Infeasible If infeasible provide justification BMP T5.10A: Downspout Full Infiltration* *Soils report required for this BMP or BMP 5.30: Full Dispersion BMP T5.14A: Rain Gardens* L *Soils report required for this BMP or BMPT7.30: Bioretention Cells, Swales, and Planter Boxes BMP T5.1013: Downspout Dispersion Systems BMP T5.10C: Perforated Stub -out Connections Feasible Infeasible If infeasible provide justification BMP T.530: Full Dispersion BMP T5.15: Permeable Pavements* F *Soils report required for this BMP or BMP T5.14A: Rain Gardens* — or BMPT7.30: Bioretention Cells, Swales, and Planter Boxes BMP T5.12: Sheet Flow Dispersion — —I or BMP T5.11: Concentrated Flow Dispersion —1 L * If you selected BMP T5.10A Downspout Full Infiltration submit 1 and 3 below. * If you selected BMPT5.15 Permeable Pavement, or T5.14A Rain Gardens in List#1, on -site soils information for sizing or infeasibility determination is required from 1 through 4 below.
