Application Process

  1. Confirm whether the parcel is inside a municipality or in unincorporated Canadian County.
  2. Check whether the work is in a mapped floodplain; the county floodplain map states a permit is required for any development in the floodplain.
  3. Contact Canadian County Floodplain Management or the Permit Office before site work, grading, fill, new structures, substantial improvements, or manufactured home placement in regulated flood areas.
  4. Obtain the applicable county form or routing instructions; if the project also needs driveway, utility crossing, septic, state highway, or OWRB/DEQ approvals, the county may direct the applicant to those agencies.
  5. Submit the completed permit package and any site/floodplain documents to the county office.
  6. Wait for review and any requested corrections, then obtain approval before work begins.
