Centerville City Zoning Code
12.50 Existing
Conditions Inventory
12.50.010 Purpose
The purpose of an existing conditions inventory (ECI) is to gather information about a development site prior to approval of a site plan in order to avoid approving plans that create land use conflicts and to protect natural and cultural resources that may be adversely affected by construction activities.
12.50.020 Scope
Before a site plan or other development approval is reviewed and approved, an existing conditions inventory, as required in CZC 12.50.040, shall be provided for the subject property and for the first 100 feet of adjoining property. The intent of an ECI is to consolidate existing information in one place, and not to require applicants to conduct original research to address the information requirements of this Chapter except as may be required by State or federal law.
12.50.030 Definitions
Certain words and phrases in this Chapter are defined in CZC 12.12 (Definitions).
