Stone removed from the Quarry was shipped from a dock on the shore of Lake Michigan. Limestone deposits spawned another quarry and tall lime kilns in what became Lime Kiln Park in the Village of Grafton.

The low laying topography of portions of Port Washington and Belgium led to the development of a harbor and permitted the fishing industry to flourish. The harbor supports commercial and sport fishing activities and sees regular visits from lake freighters delivering coal to the Wisconsin Electric Power Company plant located adjacent to the Marina.
Tourism provides a substantial income to local businesses in Port Washington.
Early settlers formed trails through Ozaukee County, which became major transportation routes to other areas of the State. Two Indian trails met in an area that grew to become the Village of Saukville. The old Green Bay Road served as the primary pathway between Milwaukee and Green Bay. Numerous small communities grew along the original trail to support the travelers, including the unincorporated area known as Hamilton in the Town of Cedarburg. Fertile ground, moderate temperatures and numerous small creeks and streams prompted development of agriculture and dairy farming.
