   CREDIT.  Ongoing reductions in the stormwater management service charge applicable to a given zoning lot or tract in recognition of the on-site or off-site systems, facilities, measures, and/or actions undertaken to reduce or mitigate the stormwater quantity and/or quality impact(s) of the zoning lot or tract that would otherwise impact the public stormwater management system. Credit shall be conditioned on the continuing performance of the mitigation systems, facilities, measures, or actions in reference to standards adopted by the stormwater management utility, and may be revised or rescinded for cause. In no case shall credits exceed the amount of the stormwater management service charge. The means and measures for identifying, issuing and obtaining credits will be provided in a credit policy approved by City Council.

   STORMWATER.  The runoff from precipitation that travels over natural state or developed land surfaces and enters a drainage system.
   STORMWATER MANAGEMENT SERVICE CHARGE.  The charge to provide stormwater services to developed property. The charge is based upon the single-family equivalent residential unit (ERU) as calculated for that property and multiplied by the single family equivalent residential unit rate.
   STORMWATER MANAGEMENT SYSTEM or SYSTEM. The system of natural and constructed devices for collecting and transporting stormwater. It includes, but is not limited to, structural drainage systems such as open swales and ditches, catch basins, pipes, inlets, storm sewers, drains, culverts, junction boxes, and other stormwater management facilities that affect the quality and quantity of stormwater located within dedicated public street rights-of-way and City of Monroe permanent drainage easements accepted by the City and all natural stormwater drainage systems.
