HomeMy WebLinkAboutGuide to Iowa City's Form-Based Zoning DistrictsGUIDE TO IOWA CITY’S FORM-BASED ZONING DISTRICTS This reflects the code as it was adopted on 11-16-2021. Staff is currently considering multiple amendments. This document will be updated as those amendments are approved. This document highlights key form-based code standards to guide those new to developing in form-based zone districts. It is not comprehensive or intended to replace the use of the Iowa City Zoning or Subdivision Codes. Form-based zoning regulations are different than the conventional approach to zoning. Form-based zoning focuses less on land use (e.g., commercial v. residential) and more on the scale (e.g., bulk and height) of the development and its relationship to the street and the public realm. The City of Iowa City’s form-based code standards are designed to improve walkability, increase housing diversity and affordability, and provide for a more sustainable neighborhood pattern. The form-based code promotes a compatible mix of non-residential uses, including neighborhood nodes. These nodes may encompass commercial areas that serve local needs as well as open spaces within walking distance. Additionally, a key goal of the code is to create a highly interconnected network of streets and paths that provide easy access to homes and neighborhood amenities.
