920.47 CREDITING/ADJUSTMENT MECHANISM.
   (a)    Credits or adjustments can be made to non-residential service charges for qualified property owners performing activities that reduce the impact of stormwater runoff to the stormwater conveyance system for retention/detention activities as follows:
      (1)   General Policies.
         A.    This program is available to all non-residential properties.
         B.    Credits will be issued on a property by property basis.
         C.    When a facility is jointly used by several non-residential properties under a joint use agreement, including deed restriction, the credit shall be prorated among the properties as a percentage of the tributary area.
      (2)   Credits Available. Retention/Detention Credits may be granted for approved facilities that reduce the quantity of stormwater and/or improve the water quality of stormwater as follows:
         A.   The minimum amount of reduction (credit) available for meeting minimum retention/detention design, construction, and maintenance standards is twenty percent (20%). The minimum twenty percent (20%) credit will be given to all eligible properties, which have constructed a retention/detention facility in accordance with City policy, provided;
            (i)    such facility meets design, construction, and maintenance standards in effect at the time of construction;
            (ii)    for which a complete credit application form has been submitted;
            (iii)    there has been provided to the City a signed right-of-entry by the owner thereof; and
            (iv)   there is paid to the City for such property a one-time, non-refundable application/inspection fee of two hundred fifty dollars ($250.00) for the first retention/detention facility and
         B.    One hundred dollars ($100.00) for each additional retention/detention facility on the same property.
         C.    The retention/detention credit is also available beyond the twenty percent reduction under the following conditions:
         D.    The amount of reduction, if any, is based upon the following:
         E.    P = (0.8-0.3*(Qa/Qt))* 100
            (v)   where:
         F.    P is the percent reduction in stormwater fee to be applied to the property.
         G.    Qa is the actual peak flow determined by calculating the peak flow of a design storm from the retention/detention facility, using the "level pool routing" technique.
         H.    Qt is the target peak flow from the design criteria, as defined in Chapter 920.
         I.    SCS standard methodologies shall be used for all calculations when determining actual peak flow.
         J.    The retention/detention credit beyond the twenty percent reduction is available upon successful completion of the application process, including the submittal of all necessary engineering calculations, documentation including as-built drawings, proof of required information, signed and stamped by a Professional Engineer registered in the State of Ohio.
         K.    The maximum amount of percent reduction (credit) available for reducing discharge from the property to zero is fifty percent (50%).
         L.    Retention/detention credit is available only for those eligible properties whose retention/detention facilities meet City design, construction and maintenance standards.
         M.    For facilities constructed after the effective date of this regulation, the credit will be made effective one year after project acceptance by the City Engineer.
         N.    Failure to operate or maintain the facility as designed shall be reason for forfeiture of the credit. The City shall notify the property owner/operator of the facility's deficiencies.
   (b)    Residential Adjustments. Any owner of undeveloped residential property may apply for a credit for the assessment for that particular property. Undeveloped residential property is a lot with a separate physical address and no impervious area. In no case, will the credit granted exceed the assessment for that residential property.
