Zoning

Re-Zoning Video Opens in new windowNew Castle County’s Comprehensive Plan estimates future conditions and, at least every 10 years, the Plan and its corresponding Zoning Code may be adjusted in response to changing conditions and circumstances. In such cases, re-zoning of County land may be necessary due to new economic conditions that render a specific land use infeasible or technologically obsolete and/or shifting community needs and priorities. Accordingly, New Castle County employs a 7-step re-zoning process that is described in this brief animated video: New Castle County Re-Zoning Explained
