Regarding directing runoff to vegetated open spaces, see the <br /> response to item 7 above. This item has been determined to be infeasible. <br /> 11. Directing rooftop runoff to infiltration areas, bioretention areas, or full dispersion <br /> systems to evaporate and transpire stormwater. <br /> Portions of the new and existing roof area have been directed to a perforated pipe <br /> system prior to discharge to the existing stormwater system. The site constraints <br /> (i.e. neighboring buildings and limited infiltration potential) do not allow for full <br /> dispersion or full roof infiltration. The perforated pipe will encourage infiltration <br /> and groundwater recharge. This item is addressed to the maximum extent feasible. <br /> 12. Minimizing impervious surfaces by reducing building footprints, road length and <br /> width, parking areas, and driveways. <br /> Where required by City of Everett Municipal Code additional landscape islands <br /> have been added to reduce the extent of pavement. Overall the project <br /> improvements result in a net reduction in impervious area. Any further reduction of <br /> impervious surfaces would require substantial additional improvements and <br /> disturbance, as well as reduce the number of parking stalls. This item is addressed <br /> to the maximum extent feasible. <br /> 13. Utilizing pervious paving surfaces such as porous pavement for roads, driveways, <br /> parking lots, or other types of drivable or walkable coverage. <br /> Where possible (in new non-pollution generating impervious surface situations) <br /> permeable pavement is proposed to encourage runoff into subsurface soils. The <br /> soil present onsite is not conducive to extensive infiltration due to the variety of fill <br /> soils and the existing Alderwood-Urban soil type. This item is addressed to the <br /> maximum extent feasible. <br /> The proposed location and extent of the above mentioned on-site stormwater BMPs are <br /> detailed and noted on the Grading and Drainage plans, Figure 5 of Appendix A. <br /> Everett Mall Plaza Parcel III Retail Expansion Stormwater Site Plan Page 11 <br />
