    As of May 6, 2014, Public Works has established the above referenced policy in order to provide a consistent framework addressing detention in re-developments which occur in watersheds that contribute to Critical Downstream Locations (Sec. 12A-5 of City Ordinances).

    * For the purposes of this policy, a “small site” is one in which detention is not already required by the flow chart in Figure 6.8.1 of the City’s Stormwater Management and Water Quality Manual; for instance, sites with 20,000 or less square feet of impervious added and/or sites which are 3 acres or less with no increase in impervious surface.
