(A) These regulations establish a stormwater management policy for the future control of stormwater runoff within the jurisdictional limits of the city. Accordingly, a combination of temporary storage and the controlled release of stormwater runoff shall generally be required for all new commercial and industrial developments, residential subdivisions, planned unit developments, and any redevelopment or other new construction on existing sites, further defined in §§ 52.05 through 52.08 of this chapter.
(B) It is anticipated in these regulations that a landowner shall be allowed to pass through existing excess stormwater runoff from tributary areas upstream from that owner’s land without storage or controlled release of the runoff. It is further anticipated that these regulations will require the controlled release of excess stormwater runoff resulting from development on an owner’s land. The controlled release rate of excess stormwater runoff from an owner’s land shall not exceed the rate of runoff which would have occurred from that owner’s land prior to the development or redevelopment of that owner’s land. It is presumed that prior to development the owner’s land had a traditional agricultural use.
