sewer system or waterbody. Measures to trap floatables for energy dissipation must also be constructed. (c) Minimize impervious surface area and maximize infiltration. Where directed by the city and based on site feasibility, projects shall use existing natural drainage ways and vegetated soil surfaces to convey, store, filter, and retain storm watet runoff befote discharge into public waters ot a storm sewer system (permanent pool areas of wet ponds tend to lose infiltration capacity and will not be accepted as an infiltration practice). The applicant shall attempt to limit the impervious surface of the developed site or subdivision by incorporating the following design considetations, 'sent with zoning, subdivision, and PUD requirements: " 5) Reducing setbacks and driveway es to conserve natural erated at the site 1) Natural vegetation preserved wherever practical 2) Narrowing street widths 3) Reducing parking lot space 4) Sidewalk locations 6) 7) 8) e, and use vegetated swales or equivalent can filter sheet flow, removing sediment and other e of concentration 10) areas by allowing runoff from small impervious areas to be eas where it can be infiltrated or filtered 11) All runoff nspouts, driveways and other impervious areas shall be directed to pervious s aces, where feasible, or unless the applicant can demonstrate that the practice is likely to result in groundwater contamination 12) Increase buffers around streams, steep slopes, and wetlands to protect from flood damage and provide additional water quality treatment 13) Use shared parking facilities consistent with zoning tequirements 14) Install serui-permeable/permeable or porous paving. (d) Pond requirements. 14
