Zoning & Subdivision Code Update

The City of Johnston has been updating its Zoning and Subdivision Codes over the last 18 months to make sure its zoning and subdivision regulations are consistent with the goals, policies, and maps in Thrive 2040, the City’s recently adopted Comprehensive Plan. In addition, specific Zoning and Subdivision Ordinance inconsistencies and issues identified by the City Council, Planning and Zoning Commission, and City Staff will be studied as part of this project.

Review and Comment on the Draft Zoning and Subdivision Codes

The draft version of the Zoning and Subdivision Regulations are now available for review and comment here.  This site allows you to review the entire draft code and insert questions/comments you have directly within the draft code, and see comments/questions others have posted.  This site will be available and comments accepted until Sunday, January 29, 2023.

This site provides an overview of changes of most interest to homeowners, business owners, developers and designers, highlights sustainability efforts and provides an overview of some property rezonings that will be necessary upon adoption of the new codes.

Will my property be rezoned as part of this process?

As part of the update process, some properties in the community will need to be rezoned. The following highlights some of the major groupings of rezonings that are proposed. There are also individual parcels that will need to be rezoned to match the future land use designation in Thrive 2040, the City’s Comprehensive Plan.  A map book is available here (PDF)which depicts the areas that are anticipated to be rezoned.  The first page contains a table of contents that helps to show, which zoomed-in map to review for properties of interest. All of the proposed rezonings will not occur at the same time as the adoption of the new Zoning and Subdivision Code. Property owners will be notified when a public hearing will be held to consider the rezoning of their property.   To learn more about what some properties may be rezoned visit this link.

What are the Zoning and Subdivision Codes?

The Zoning Code is the set of rules that identifies how individual properties within the City can be used. It also sets standards for how buildings may be developed or changed. The Zoning Code is structured by dividing the City into districts and then identifying what can occur in each district. The Zoning Map, available here, shows where the City’s zoning districts are located. The Zoning Code also has standards that apply to all districts, such as parking, landscaping, screening, signage, etc.

The City’s Subdivision Regulations shape how properties can be subdivided into smaller parcels for development or sale. The regulations include standards pertaining to lots, streets, infrastructure such as water and sewer, and public areas. 

The City’s current zoning and subdivision regulations are available here

What is Thrive 2040?

Thrive 2040 is the City’s recently adopted Comprehensive Plan. It is a document that is a tool for guiding the growth, redevelopment, and overall improvement of the City. While the most recognized part of the Comprehensive Plan is its land-use plan, Thrive 2040 also includes a vision statement, guiding principles, goals, policies, and implementation initiatives that direct actions related to natural resources, transportation, economic development, housing, parks, trails, and open space, and utilities. Thrive 2040 also incorporates the 10 Iowa Smart Growth Principles throughout the Plan. More information about Thrive 2040 can be found here

Why do the Zoning Subdivision Codes need to be updated?

These potential updates will address specific standards in some zoning districts, parking, landscaping/screening, stormwater and natural resources, and definitions sections of the Zoning Code. In addition, the City’s last update/rewrite of its Zoning Ordinance occurred in 1982. While amendments have been made, a collective update and modernization of the Zoning and Subdivision regulations have not occurred.

How can I be involved?
