Where the City Engineer determines that site constraints exist in a manner that compromises the intent of this chapter to improve the management of storm water runoff as established in this chapter, practical alternatives may be used to result in an improvement of water quality and/or a reduction of storm water runoff. Such alternatives must be in keeping with the intent and likely cost of those measures that would otherwise be required to meet the objectives of this section. Such alternatives shall achieve the same level of storm water quantity and quality control that would be achieved by the on-site controls required under this regulation. When possible, all practical alternatives shall be implemented within the drainage area of the proposed development project. Alternatives shall be implemented in the same Hydrologic Unit Code (HUC) 14 12 watershed unit as the proposed development project. The mitigation ratio of the water quality volume is 1.5 to 1 or the water quality volume at the point of retrofit, whichever is greater. An inspection and maintenance agreement shall be established to ensure operations and treatment in perpetuity. Prior written approval from Ohio EPA shall be obtained. Practical alternatives can include, but are not limited to:
(a) Fees shall be paid in an amount specified by the City Engineer. The City shall apply these fees to SCMs that improve the existing water quality.
(b) Implementation of off-site SCMs.
(c) Watershed or stream restoration.
(d) Retrofitting of an existing SCM.
(e) Other practices approved by the City Engineer in keeping with the intent of this section.
