§ 50-198. Stormwater management facilities.

The subdivider shall construct stormwater drainage facilities, adequate to serve the land division or condominium development, which may include curbs and gutters, catchbasins and inlets, storm sewers, open channels, water retention and detention facilities and settling basins, including bioretention basins and infiltration trenches. In addition:

(1)

All such facilities shall be of adequate size and grade to hydraulically accommodate the maximum potential volumes of flow and shall be so designed as to prevent and control soil erosion and sedimentation and to present no hazards to life or property. The type of facilities required and the design criteria shall be determined by the village engineer/DPW director. All facility plans shall be reviewed and evaluated on a case-by-case basis taking into consideration the nature of the topography and discharge location within, and adjacent to, the village. The subdivider shall install the size and type of stormwater management facilities proposed to be constructed in accordance with plans and specifications approved by the village engineer/DPW director based on the stormwater management requirements in chapter 76 of the Village Municipal Code.

(2)

The subdivider shall assume the cost of installing all stormwater conveyances and storage facilities necessary to serve the proposed development. If larger conveyance and storage facilities are required to accommodate flows originating from outside of the proposed development, or to avoid flooding attendant to increased flows downstream of the proposed development caused not by the development but by preexisting development upstream, the cost of such facilities shall be prorated in proportion to the contributing rates of flows and the excess cost shall be borne by the subdivider.
