Waukesha County, the western suburban county that has become the fastest-growing and most-developed part of the Milwaukee MSA. The eastern corridor along I-94 contains Brookfield (the county's largest city by employment), Elm Grove, New Berlin, Menomonee Falls (home of Kohl's headquarters), Pewaukee, and Waukesha (the county seat). Further west are Delafield, Hartland, Oconomowoc, and the Kettle Moraine lakes area (Lac La Belle, Okauchee Lake, Pewaukee Lake, Nagawicka Lake). Mukwonago and Muskego anchor the southern Waukesha County residential corridor.
