Overview of Annexation and Boundary Changes

Annexation is the process by which Aurora adds adjacent territory to its corporate limits; boundary changes can include voluntary annexation, annexation by ordinance, and property detachment in limited circumstances. Common reasons include extending utilities, clarifying zoning authority, or consolidating parcels. Typical participants are property owners, the Planning Division, City Council, and affected service districts.

Steps in the Typical Process

  • Submit petition or application to the Planning Division according to submittal checklist and schedules.
  • Staff review and interdepartmental referrals for utilities, engineering, and public works.
  • Public notice and a Planning Commission or Council hearing; neighbors may testify.
  • City Council considers ordinance to approve, deny, or approve with conditions.
  • Recording of annexation ordinances and updating maps and tax/service records.
Petition completeness determines scheduling speed.
