Marana enforces erosion and sediment control through the Land Development Code grading and drainage provisions and the EPA NPDES stormwater permit program. Construction sites disturbing one acre or more must obtain an Arizona Pollutant Discharge Elimination System (AZPDES) Construction General Permit.
The Marana Land Development Code requires erosion and sediment control plans for all development projects involving grading or land disturbance. The Sonoran Desert terrain around Marana, particularly in the Tortolita Mountain foothills and Santa Cruz River floodplain, is highly susceptible to erosion during monsoon storms. Construction sites disturbing one acre or more must file a Notice of Intent with the Arizona Department of Environmental Quality (ADEQ) and obtain coverage under the AZPDES Construction General Permit (CGP). The CGP requires a Stormwater Pollution Prevention Plan (SWPPP) with best management practices for erosion control including silt fencing, stabilized construction entrances, fiber rolls, and sediment basins. Marana building inspectors verify erosion control measures during site inspections. Post-construction permanent erosion control such as riprap, retention basins, and stabilized slopes must be maintained by the property owner. The Pima County Regional Flood Control District also has jurisdiction over erosion hazard areas along washes and watercourses within the Marana planning area.
AZPDES permit violation: ADEQ administrative penalties up to $25,000 per day. Failure to implement erosion control: Marana stop-work order and grading permit revocation. Damage to downstream properties: civil liability and additional town penalties.
