Beginning with the 2018 Construction Season

The City of Davenport will be adopting SUDAS, Statewide Urban Design and Specifications, as well as a supplemental specification beginning with the 2018 construction season.

As part of the process of adopting new standards, we invited engineering, construction and utility agencies to review and comment on the proposed supplemental specifications. The first review and comment period closed in August 2017, and the second review period closed in February 2018.

The supplemental specifications will be placed for council consideration and approval in March, with adoption anticipated on March 28, 2018.

We would like to thank all agencies who participated for taking time to review and comment on the proposed specifications.

The Zoning Ordinance is a critical implementation tool of the City’s Comprehensive Plan, which is used to guide development and redevelopment in the City. The Zoning Ordinance itself contains specific rules for development while the companion Zoning Map lays out zoning “districts” that outline specific land uses, densities and design criteria for specific locations.

Changes to the Zoning Ordinance and map (rezonings) can only be accomplished through an open process by the Plan and Zoning Commission and City Council.

The Zoning Ordinance can be found under Section 17 of the Davenport City Code.

Davenport is currently updating the Zoning Ordnance to ensure the current and future needs of the City are met. Stay tuned for future updates on this important project.
