Phoenix Stormwater Quality Protection Code

The city code defines green stormwater infrastructure as infrastructure constructed with a range of measures that use plant or soil systems, permeable pavement or other permeable surfaces or substrates, stormwater harvest and reuse, or landscaping to store, infiltrate, or evapotranspirate stormwater and reduce flows to the public storm drain system or to surface waters. These features are also sometimes referred to as low impact development (LID). The City Manager will encourage the use of green stormwater infrastructure to control the release of pollutants into the public storm drain system.

A person who conducts an activity on nonresidential property or conducts an activity for a fee or charge on residential property that has the reasonable potential to affect the quality or volume of stormwater impounded upon or released from the property, regardless of whether it is raining at the time, shall prepare a written stormwater management plan.
