From 1991-2008, the Johnson County Museum surveyed a large percentage of the pre-1950 architectural resources in the county. The survey and resulting data provides a basis for comprehensive preservation planning and for education about the county’s historic resources. An executive summary details the highlights, and the full 150-plus page report is available by request. Photographs of each individual property surveyed – all 9,213 of them -- are also accessible via the online database www.JoCoHistory.org. For more information about the Johnson County Museum's historic building survey project email or call 913-715-2550.
