(A) Maintenance requirements. Credit may only be allowed for lots and parcels of real property where structural controls are maintained in fully functional condition and according to maintenance criteria and design standards required by city ordinance.
(B) Direct discharge credit. Credit may be granted on the basis of location of a given property in relation to the O'Connor Ditch, Little Mississinewa and other legal public drains under the control and jurisdiction of the Randolph County Drainage Board, if such property directly discharges its storm water to such drain in conformance with all maintenance criteria and design standards as applicable.
(C) Voluntary controls. Voluntary controls and/or upgrades of existing private storm water facilities through retrofitting that exceed the city's standard storm water abatement design criteria may be considered for credit on a case-by-case basis considering the impact of the controls on the city's storm water system, as determined by the DSM.
(D) Industrial NPDES permit credits. No credit shall be allowed for industries in compliance with Federal laws and regulations regarding industrial storm water discharge permits.
(E) Pollution reduction. No credit shall be allowed for voluntary efforts to reduce the amount of pollutants in a user's storm water runoff or for improvements to the quality of a user's storm water discharge.
(F) Regional basins. Credit will not be granted to properties draining into ponds or basins maintained or owned by the city. Credit may only be considered for privately owned and maintained regional controls.
(G) Federal, state, city, county and private roadways. Streets, roads and highways shall be given 100% credit as they form an integral part of the Storm Water System. The surface water control system incorporated in design of roadways are areas engineered to convey all design runoff without street flooding. Primary elements of the drainage system yield community-wide benefits and are installed to service the general public's interests.
