The offices of the SCEDC were initially open for business in January 2010, but the organization has significant historical connections within the county.
The Sheboygan Development Corporation (SDC) was formed in 1984, as local business leaders identified a need for a private-public partnership to help facilitate development within the City of Sheboygan and surrounding areas. The SDC was originally focused on development projects within the City of Sheboygan, and was involved in several high-profile projects, including the South Pier redevelopment project on the lakefront, development and implementation of the Harbor Centre Plan which resulted in construction of the Harbor Centre Marina, and support for creation of a Great Lakes Aerospace Science and Education Center (GLASEC).
In response to several major local corporate relocations in 2008 and 2009, which had an impact on employment throughout Sheboygan County, leaders from both the private and public sectors galvanized efforts to develop a comprehensive county-wide program to assist businesses and entrepreneurs and attract new investment, to improve the economic well-being of the residents and businesses of the county. In August 2009, the SDC Board of Directors amended its articles of incorporation and evolved into a new organization with a broader county-wide focus and representation, the Sheboygan County Economic Development Corporation.
