Johnston Comprehensive Plan and Zoning Update

HKGi has led the development of the last three Comprehensive Plans for the City of Johnston, Iowa.  The most recent comprehensive planning process, the Thrive 2040 Plan, attempts to address a host of issues that have affected the community and will continue to have an impact in the next 20 years.

Housing was a significant issue to address during this planning process, particularly as the community is projecting the addition of 4,500-5,000 new households and between 11,000 and 13,000 new people by 2040.  To accommodate the growth in households and the need for affordable and mid-price homes, the community will need to diversify its housing stock and increase the density of housing across the community.  HKGi worked with the community to identify where that growth can take place and what shape it will take.  HKGi and the community also explored development scenarios for eight of the City’s growth areas and other redevelopment areas.
