The following rules shall govern the design of improvements with respect to managing stormwater runoff:
(a) Methods of Determining Storm Water Runoff Rate and Volume. Calculating runoff discharge rate and total volume drainage and detention facilities shall be made using the most recent version of the Stormwater Management Manual published by the Summit County Engineer and/or as requested by the City Engineer.
(b) Drainage Facility Design.
(1) Developers of subdivision developments, any new commercial, industrial, institutional or utility development that propose to drain storm water into the City's storm water system shall construct drainage facilities designed to hold the 100-year rain event using post construction parcel hydrology. Storm water can be released from the ponds at a maximum of the 5-year pre-construction hydrology rate.
A. All drainage facility shorelines and basin bottoms shall be planted with native Ohio vegetation in an effort to capture and assimilate water pollution. This ordinance does not regulate additional water quality ponds as mandated by the EPA or any other County or State agency.
(2) The developer of an individual lot that proposes to drain storm water into the City's storm water system shall deposit sufficient funds into the City of Reminderville Storm Water Pond Fund for the City to manage the stormwater. Such funds shall be used by the City to 1) purchase strategic land, 2) create stormwater ponds, 3) drainage way maintenance, or 4) be placed in the stormwater general fund.
A. The amount of such deposit shall be calculated using the selling price of current land, the space needed to capture the additional volume of water flowing from the property during the 100-year rain event due to construction/improvements, and the associated construction cost of the basin to accommodate the additional volume. The City Engineer shall perform this calculation and the owner and/or builder shall be responsible for any costs associated with making the cost determination.
B. It shall be the responsibility of the City to inspect and maintain these retention and detention ponds.
