(A) The city utilizes a Utility Impact Board to review all permit applications that are submitted to the Building Commissioner's Office. This Board is comprised of the Department heads of the Sanitary, Water and Street Departments as well as the MS4 Operator.
(B) The Building Commissioner and Utility Impact Board must review all permit applications submitted for new construction or substantial improvements to determine whether the proposed construction or improvement has reasonably addressed and adopts adequate drainage methods to abate the effects of surface water runoff on adjoining properties and/or the city's stormwater system. Discharge of stormwater to a sanitary sewer is prohibited. Stormwater runoff to a combination sewer system will only be allowed if developer funded flow mitigation improvements and/or on site retention/detention is provided with controlled outlet as approved by city officials. In no case, shall the peak flow rate or the total runoff volume in 24 hours be increased from pre-development to post-development conditions. At a minimum all such applicants must submit detailed calculations with a licensed professional engineer's certification that adequate provision for storm or surface water has been made and that, by the construction or improvement at proposed, no increased storm or surface water runoff shall occur to the detriment of adjoining properties or the city's collection system.
