Stormwater Runoff in connection with Redevelopment shall be managed by onsite measures that result in treatment of 100% of the additional proposed Impervious Surface area and at least 30% of the existing Impervious Surface area, preferably using Filtration and/or Infiltration processes, or, if they would result in greater overall water quality, LID strategies implemented to the maximum extent practicable to treat Stormwater Runoff generated from at least 60% of the total Impervious Surface on the site.
