City standards require treatment of storm water ru�loff from hydraulically-connected pavement prior to discharge of the storm water from the site. 1 S. Storm water treatment is required when 5,000 square feet or more of hydraulically-connected pavement is created and/or redeveloped by a project. Treatment of storm water runoff from hydraulically-connected pavement must occur, per City standards, prior to discharge of the storm water from the site, or to a stream, wetland, or underground infiltration system. � If suitable soils exist on the site, surface storm water infiltration systems (e.g., pervious pavers or surface ponding areas and/or swales) may be used to avoid creating hydraulically-connected pavement from a storm water treatment standard. ➢ From a storm water treatment standpoint, for a paved area to be considered hydraulically- disconnected, storm water runoff from at least the 6-month, 24-hour storm must be fully retained and/or inf ltrated. 19.
