(A) Detention. Runoff may be stored in temporary or permanent basins, or through rooftop or parking lot ponding, or percolation storage, or by other acceptable means and installed in accordance with the UDO. Detention may be allowed through off-site facilities with the approval of the City Engineer.

(B) Open Channels. Maximum feasible use must be made of existing drainageways, open channels, and drainage swales that are designed and coordinated with the design of building lots and streets.

(C) Streets and Curbs. Streets, curbs, and gutters are an integral part of the stormwater runoff management system. To the maximum extent possible, drainage systems, street layout and grades, subdivision lot patterns and the location of curbs, inlets, site drainage and overflow swales must be concurrently designed in accordance with the standards set forth in this title.

(D) Enclosed Conveyance System. Enclosed conveyance systems consisting of inlets, conduits, and manholes may be used to convey stormwater runoff.

(E) Stormwater Treatment Facilities. Stormwater treatment facilities are those facilities designed to capture and control runoff from frequent storm events in order to remove pollutants and reduce downstream channel erosion. Examples include, but are not limited to, rain gardens, bioretention cells, wetlands and structural filtration systems. Stormwater treatment facilities should be located on site, closest to the source of pollution.

(F) Other. The stormwater runoff management practices enumerated in this section are not an exclusive listing of available management practices. Other generally accepted practices and methods may be utilized where approved by the City Engineer. (Ord. 22-52 § 7, 2022; Ord. 09-25 § 2, 2009.)
