New development and grading in Mohave County must control runoff on-site and keep it out of desert washes. Land disturbance of one acre or more needs an ADEQ AZPDES construction stormwater permit.
Across Mohave County's Mojave Desert terrain, from Kingman to the Colorado River, monsoon storms send fast, muddy flows down arroyos and washes. County engineering reviews drainage for new construction and grading so stormwater is retained or conveyed without worsening flow onto neighbors or downstream lots. Projects disturbing one acre or more must obtain Arizona's AZPDES construction general permit from the Arizona Department of Environmental Quality and keep a stormwater pollution prevention plan on site. Kingman, Lake Havasu City, and Bullhead City run their own municipal storm-sewer and drainage programs.
Discharging sediment or pollutants into washes or storm drains draws ADEQ enforcement and fines. Building without required drainage review can trigger stop-work orders and corrective grading.
