zonewide

Zonewide is an adjective describing something that applies across an entire defined zone or geographic area, rather than to a subset. The term is widely used in urban planning, emergency management, transportation, and information technology to denote uniform applicability across a larger region.

In zoning and land-use planning, a zonewide regulation or code applies to all parcels within a zoning district or across the entire zone, ensuring consistent standards and compliance.

In public safety and emergency management, zonewide alerts, advisories, or restrictions propagate to all jurisdictions within the designated zone, enabling coordinated notification and response.

In transportation, zonewide service changes or fare schemes cover an entire zone or tiered area rather than individual routes or stations, facilitating scalable management.

In information technology and cybersecurity, zonewide policies, updates, or monitoring apply to all systems within a defined network zone, allowing centralized control and uniform security.

Implementation typically requires clearly defined zone boundaries and governance or infrastructure capable of propagating changes or messages across the zone. Limitations can arise from overlapping or ill-defined zones, or from variations in local rules and conditions across different parts of a zone.

The etymology is straightforward: zone + wide. See also citywide, statewide, nationwide.
