§ 34-1354. Surface water management.

(a)

Drainage (surface water management) systems shall be designed so that post-development conditions shall approximate predevelopment conditions to the maximum extent possible. Where predevelopment conditions in the surrounding area are characterized by flooding of existing uses, drainage design involving the new development should reduce existing problems to the maximum extent feasible. Where necessary, the village council may require the modification of the development project to ensure that such requirement is met.

(b)

Drainage systems should be designed so as to maintain or improve water quality to the maximum extent feasible, and to meet applicable standards of the state and/or water management district. In addition to water quality where surface water runoff leaves the site, water quality shall be maintained in lakes and canals where surface water ultimately drains. Where necessary, the village council may require the modification of the development project to ensure that such standard is met.

(c)

Drainage shall be designed to maintain the predevelopment viability of natural areas and groundwater recharge. To the maximum extent feasible, surface water runoff should be directed to groundwater recharge and/or natural drainage areas rather than being directed to manmade canals.

(d)

The developer of a site shall be responsible for the design and construction of the drainage system so as to comply with the surface water management requirements of this section, as well as the applicable requirements of other state, regional and/or local agencies.

(e)

Based on advice from the appropriate agencies, all drainage plans shall be designed utilizing best management practices (BMPs) as established by the applicable areawide water quality plan.

(f)

Site designs shall utilize retention of natural vegetation and vegetative cover, and shall minimize impervious surfaces to the maximum extent feasible to allow maximum infiltration.
