Pittsburg Municipal Code (PMC) - Irrigation Practices

single sprinklerExcessive irrigation can contribute to pesticides flowing into the storm drains, creek, and bay. On December 20, 2010 the City of Pittsburg revised the City’s previously adopted water-efficient landscape ordinance in recognition of the mandate in Assembly Bill 1881(Laird) and in accordance with the State Department of Water Resources’ model water efficient landscape ordinance intended to ensure the conservation of water in irrigated landscaped areas. The revised ordinance outlines the current standards and requirements for projects creating or rehabilitating landscaping. See PMC Section 18.84.31 for project applicability.

Runoff due to excessive irrigation is considered to be a non-stormwater illicit discharge and is a violation in accordance with PMC 13.28.060, Prohibited Discharges. Any persons found to be violation will be issued notices of correction and may be subject to fines. Best management practices for landscape maintenance and efficient irrigation practices are to be used. Excessive irrigation runoff can be mitigated by reducing the irrigation run time and/or adjustments to spray heads to prevent overspray.
