(a) In the event the amount of impervious area on a non-residential property is increased above that assigned by the City of Rossford, an adjustment may be made to the ERU multiple assigned to the property to properly reflect the amount of impervious area. The new ERU multiple shall be billed from the date on which the City mails a notification of the change to the owner of the property and shall not be stayed by an appeal under Section 935.10. If the Department of Public Works finds that it has been under billing a non-residential property as a result of the increase in impervious area, the owner may be charged for the difference between the amount actually billed and the amount that should have been billed for a period of time not to exceed one year prior to the date of the Department's mailing of a notification to the owner that an adjustment is being made to the property's ERU multiple.
(b) The owner of a non-residential property may apply for an adjustment to the ERU multiple if the owner has taken certain actions that reduce the impact of storm water runoff to the storm water system. The maximum adjustment that may be made to the ERU multiple for any non-residential property is 50% consisting of any one or more of the following credit options:
(1) Brownfield reuse 10%
(2) Detention/retention 30%
(3) Direct discharge 10%
(4) Forested (stream) buffer/grass filter strip 30%
(5) Industrial NPDES 10%
(6) Open-channel maintenance 30%
(7) Sediment pond 30%
(8) Swales 30%
(9) Wetpond and extended detention 30%
