Land disturbance of one acre or more in Coconino County needs coverage under Arizona's AZPDES construction stormwater general permit from ADEQ, plus a stormwater pollution prevention plan and county drainage review.
Construction that disturbs one acre or more, or is part of a larger common plan, must obtain coverage under the Arizona Department of Environmental Quality's AZPDES Construction General Permit and prepare a Stormwater Pollution Prevention Plan (SWPPP). On the Colorado Plateau, snowmelt and violent summer monsoon storms move sediment fast, and runoff off the Museum and Pipeline Fire burn scars has overwhelmed Flagstaff channels. Coconino County's drainage and grading provisions add on-site retention and detention requirements for new development, and the City of Flagstaff runs its own stormwater program. Discharging sediment or pollutants to the Rio de Flag or other washes is prohibited.
Disturbing an acre or more without AZPDES permit coverage draws ADEQ enforcement and penalties. Uncontrolled sediment discharge to a wash or the Rio de Flag brings stop-work orders and fines.
