Legal Authority and Scope

The City regulates development in mapped flood hazard areas through municipal ordinances and building regulations; specific standards are set at the city level and often reference federal flood maps for delineation.[1] City building and planning review incorporate floodplain compliance into permit approvals and local code enforcement.

Civil fines, stop-work orders, and corrective orders are available remedies under city authority, and violations may be subject to administrative citations or prosecution where the municipal code permits. If a specific fine amount or escalation schedule is required by law, it must appear in the municipal code or specific fee resolution cited by the city; such amounts and escalation rules are not specified on the cited permit pages below.[1]

  • Enforcer: Building & Safety and Planning divisions handle inspections and enforcement; complaints and permit inquiries go to the city permit office.[2]
  • Common sanctions: stop-work orders, corrective orders, administrative citations, withholding of occupancy permits; criminal or civil prosecution may follow where authorized in code.
  • Fine amounts and daily penalties: not specified on the cited permit pages; see municipal code or city fee resolution for exact figures.[1]
  • Appeals and review: appeal routes often run through the city’s appeals board or planning commission; specific time limits for filing appeals are not specified on the cited permit pages and must be confirmed in the governing ordinance or appeal procedure notice.[1]
If you receive a stop-work order, contact Building & Safety immediately to learn required corrective steps.
