Mayfair Reservoir Expansion

Westchester, Illinois

Following two storm events in 2010 and 2013 that exceeded the 100-year water surface elevations and caused flooding for a significant number of residences, V3 was retained by the Village to evaluate the expansion of the Mayfair Reservoir. V3 performed storm alternatives analysis to determine the most cost effective option to protect the impacted residences from intense rainfall. Recommendations included the expansion of the Mayfair Reservoir, construction of a relief sewer, local storm sewer improvements and evaluation of an existing stormwater lift station.
