Tucson requires grading permits for earthwork that alters natural drainage patterns under the Unified Development Code. The city mandates that post-development drainage must not adversely impact adjacent properties. Development must accommodate the unique desert drainage patterns including sheet flow and wash channels that activate during monsoon storms.
Grading permits are required for cuts or fills exceeding specified thresholds. Drainage reports prepared by a registered engineer are required for most development projects. The city's standards require that development not increase runoff volume or peak discharge to downstream properties. Retention basins, area drains, and engineered channels are common solutions. The UDC includes specific provisions for preserving natural washes and drainage corridors.
Grading without a permit can result in fines, restoration orders, and stop-work orders. Diverting drainage onto neighboring properties can trigger code enforcement action and civil liability.
