Where the Community Engineer determines that site constraints exist in a manner that compromises the intent of this ordinance to improve the management of storm water runoff as established in this ordinance, 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. All practical alternatives shall be implemented within the drainage area of the proposed development project unless specifically authorized in writing by the community engineer.
(a) Implementation of Off-site Storm Water Management Practices: The use of any off-site Post- Construction BMPs requires written approval from Ohio EPA and this approval must be received prior to design approval and/or issuance of any building permits. Practical alternatives to be considered include:
(1) Retrofitting of an existing storm water management practice.
(2) Watershed or stream restoration.
(3) Fees paid in an amount specified by the Community Engineer. The Community shall apply these fees to storm water management practices that improve the existing water quality.
(b) Use of Alternative Post-Construction BMPs: Permitees must supply written approval from Ohio EPA to use Post-Construction BMPs that have been demonstrated to be equivalent to the effectiveness of those listed in Table 2 above. Approval from Ohio EPA must be received prior to design approval and/or issuance of any building permits.
(c) Other practices approved by the Community Engineer in keeping with the intent of this section. (Ord. 2013-41. Passed 9-24-13.)
