How an Issue or Idea Becomes a Land Use Regulation

  1. Ordinance Development
    Staff research issues, work with identified interested parties, and develop potential code or plan language to address identified issues.
  2. Ordinance Filing
    Once proposed code or plan changes are developed, those changes are officially submitted or “filed.”
  3. Public Notice & Public Hearings
    Notice of filed ordinances and public hearings are published and posted on the County webpage. The Planning Commission conducts a public hearing(s) and makes a recommendation to the Board of County Commissioners. The Board conducts a public hearing(s) and makes a decision on the ordinance.
  4. Ordinance Engrossment
    The ordinance may be adopted as proposed or may be engrossed (changed) by the Board. If the Board engrosses a land use ordinance, further public notice is provided and additional hearings are scheduled.
  5. Board Decision
    At the conclusion of public hearings, the Board either adopts, rejects, or continues a land use ordinance to a specific future date.
  6. Ordinance Effective
    If adopted, most land use ordinances become effective 30 days after adoption.
