(a) When the Village Engineer determines that site constraints compromise the intent of this regulation, off-site alternatives may be used that result in an improvement of water quality and 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. When possible, all practical alternatives shall be implemented within the drainage area of the proposed development project. Such alternatives shall meet the following standards:
(1) The same level of storm water quantity and quality control that would be effectuated by the on-site controls required under this regulation is achieved.
(2) The alternatives are implemented in the same Hydrologic Unit Code (HUC) 14 watershed unit as the proposed development project.
(3) The mitigation ratio of water quality volume is 1.5 to 1 or the water quality volume at the point of retrofit, whichever is greater.
(4) An inspection and maintenance agreement as described in Section 1254.16(C)(5) is established to ensure operations and treatment in perpetuity.
(5) Prior written approval from the EPA is obtained.
(b) Alternative actions may include, but are not limited to the following. All alternative actions shall be approved by the Village Engineer.
(1) Fees, in an amount specified by the Village, to be appliced to community-wide storm water management practices.
(2) Implementation of off-site storm water management practices and/or the retrofit of an existing practice to increase quantity and quality control.
(3) Stream, floodplain, or wetland restoration.
(4) Acquisition or conservation easements on protected open space significantly contributing to storm water control such as wetland complexes.
