Zoning

Welcome to the Zoning Homepage. Most people wonder "What is zoning?" The Supreme Court upheld the authority of governments to enforce zoning regulations in 1926 in the landmark case of Village of Euclid, Ohio v. Ambler Realty ExternalLink.gif. Since then, almost every major city has adopted a zoning code. Zoning regulates land use, including the size, shape and permitted uses of lots and structures. Zoning dictates where people live and where they work. It controls the size of our houses and the location of stores. In most cities, it is the primary tool that guides land use.

What Does Zoning Affect?

Local governments in Illinois are granted extensive powers from the state via home rule ordinances. One of those powers is to create and enforce regulations that promote public safety, health and general welfare. In 2000 Rock Island County adopted the Quad City Unified Ordinance. Since then we have made some minor changes to the ordinance, you can find a digital copy in our downloads section. Below you will find some common topics.

Zoning can preserve natural features, promote infill development and mixed-use development, minimize dependence on the car, provide public community spaces and otherwise help make cities and towns more livable.

Uncoordinated development at the suburban fringe can permanently destroy farmland and wildlife habitats and exacerbate traffic gridlock. Regional and local policies to promote infill development can direct new jobs and housing to mature communities that have the necessary infrastructure to support them. Zoning, for instance, can prohibit new development on certain parcels and encourage more compact development on others.

Zoning must also consider the market demand for land uses, since a zoning map essentially allocates the amount of land available for industry, commerce and housing within the city. The zoning code should have the flexibility to adapt to changes in the market's demand for space.

Zoning will rarely be the only sensible growth tool communities use, but it can help communities reach their land-use goals when combined with effective planning.
