3. Not selected since a higher option is feasible. <br /> 4. Perforated Stub-Out Connections were not selected for this project since higher <br /> priority BMP's were selected. <br /> Other Hard Surfaces: <br /> 1. Full dispersion was found to be infeasible for this project site, as previously <br /> mentioned. <br /> 2. Permeable pavement was considered next. Based on the on-site soils, permeable <br /> pavement was found to be feasible on Lot 2. Therefore, permeable pavement <br /> should be used for the driveway surfaces proposed on Lot 2. Refer to <br /> geotechnical report for recommendations. <br /> 3. Bioretention was Not selected since a higher option is feasible. <br /> 4. Runoff from the road surfaces will be directed to a depressed planter strip/swale to <br /> conveyance/treatment prior to entering the downstream conveyance system. <br /> Runoff from the alley drains to an existing CB. <br /> Finally, per List #2 lawn and landscaped areas must implement post-construction soil <br /> quality and depth in accordance with BMP T5.13 in Volume 5, Chapter 5. Therefore, BMP <br /> T5.13 will be applied to all areas of lawn/landscaping on this site to further provide filtration <br /> and shallow infiltration of site pervious runoff. <br /> Zillah Lot 2 SFR 18-0605 <br /> Aug.2019 Page 11 <br />
