Creekview Meadows Flooding Analysis and Solution

« Return to Project Search

The Village of Baldwin retained Ayres to provide topographic survey and concept analysis of the drainage in the Creekview Meadows subdivision. During extreme rainfall, the existing stormwater pond in the middle of the subdivision would overtop and flood adjoining properties. A number of heavy storms in 2003, 2007, and 2010 resulted in repeated flooding for landowners.

Ayres modeled the existing conditions and provided alternatives to the Village. The preferred solution was to add freeboard capacity for the pond berms and to route the pond’s emergency overflow to a different location that wouldn’t cause flooding to homes that had been built in harm’s way.

The completed project increased the height of the top of the pond for freeboard; created an emergency spillway on the opposite end of the pond; and constructed a 10-foot bottom drainage swale along the downstream portion of the subdivision with sufficient capacity for the 100- and 1,000-year floods without overtopping the pond or the drainage swale.
