All single-family residential developments under five (5) acres in size and all other development under one acre in size shall pay a fee of twelve thousand dollars ($12,000.00) for each acre-foot of detention which would be required under this division rather than installing detention facilities on the property, unless specifically directed to do otherwise by the county engineer. The county also shall have the option for larger properties of requiring a fee of twelve thousand dollars ($12,000.00) for each acre-foot of detention needed in lieu of the applicant building a basin on site provided the property will discharge stormwater to the county's, city's, or village's storm sewer system.
In instances where regional benefits and economies of scale can be achieved, it will be permissible for adjacent properties to utilize a common regional detention basin. Applicants shall have the option of paying a fee of twelve thousand dollars ($12,000.00) for each acre-foot of detention required, with the approval of the county engineer, to the county so that the county can build regional facilities or the applicant and adjoining properties can jointly build the necessary facilities themselves.
