Mesa Storm Drain Law: Property Owner Responsibilities
In Mesa, Arizona, property owners share responsibility for preventing stormwater pollution and keeping on-site drainage features and adjacent curb inlets clear. This guide explains who must maintain what, how to report clogged or damaged storm drains, inspection and enforcement pathways, and practical steps to stay compliant under Mesa city rules and programs.
Who is Responsible?
Responsibility typically falls to the private property owner for maintenance of drainage features on their lot, and to the city for public right-of-way inlets and mains. For program details and reporting options see the City of Mesa Stormwater Quality program information page[1]. The municipal code sets standards for nuisances and illicit discharges; see the City of Mesa Code of Ordinances for applicable provisions and definitions. [2]
Routine Maintenance Duties
Common owner duties include removing leaves, sediment and trash from gutters, ensuring downspouts and swales convey water without eroding adjoining properties, and preventing oil or other pollutants from entering curb inlets. When work alters drainage patterns or requires grading, a permit from the city may be necessary.
- Clear fallen leaves, sediment and trash from gutter lines and inlet grates on or adjacent to your property.
- Repair or replace damaged grate covers or private drain components to prevent blockages.
- Obtain required permits before changing on-site drainage or performing work that affects stormwater flow.
Penalties & Enforcement
Enforcement is carried out by the City of Mesa through its Public Works/Stormwater program and code compliance units; specific inspection and complaint routes are provided by the city website and ordinance references. [1]
