ABSTRACT
Zoning for industry has historically followed the Euclidian principle of single-purpose districts. Increasingly, nonindustrial uses have been permitted through district-wide rezonings, incremental zoning changes, special permits, variances, and tolerance of illegal conversions. These scenarios are as true in Rust Belt cities like Cincinnati as in hot real-estate markets such as San Francisco. To hold market forces at bay, some municipalities have responded with rigidly regulated, single-purpose industrial zones. Other cities have employed mixed use to reconcile industry with higher-value, competing uses. The nature and pros and cons of each of these basic approaches are described in this chapter, leading to a discussion of whether there are ways to regulate land uses for manufacturing that are proactive in nature.
