Summary
El Cajon bars landscape irrigation runoff and overspray onto adjoining property, walkways, or streets under Municipal Code Section 17.195.200, with the director able to order water audits and the city council empowered to fine violators. During a declared water emergency, Section 17.195.230 lets the council defer new landscaping installation citywide until the emergency passes.
Property owners shall prevent water waste resulting from inefficient or improperly maintained landscape irrigation on their property. In order to ensure that water is not wasted, the director may require water audits and may penalize property owners for water waste such as runoff leaving the target landscape due to low head drainage, overspray, or other similar conditions where water flows onto adjacent property, non-irrigated areas, walks, roadways, parking lots, or structures. Penalties for water waste resulting from inefficient landscaping may be imposed in the form of monetary fines, the amount of which shall be determined by the city council based upon the magnitude, duration and/or frequency of the ordinance violation.

Full Breakdown
' The same section requires every required landscape area to incorporate specific water-saving techniques, including drought-tolerant planting, hydrozoned irrigation circuits, mulch, and drip or low-evaporation irrigation systems, and it flags early morning watering as the preferred schedule because evening irrigation leaves foliage wet overnight and more prone to fungal disease. It also carries a location-specific caution against overwatering on the west rim of the El Cajon Valley, Fletcher Hills, because of that area's expansive soils and landslide risk. 230, Water emergencies, lets the city council, on a majority vote declaring a water emergency, defer installation of required landscaping citywide, except for landscaping installed for erosion control or fire protection, provided a suitable guarantee is posted to cover eventual installation, and the council may still require a full landscape documentation package and water budget for any deferred project.
Violations & Fines
Irrigation runoff or overspray that leaves the target landscape and reaches a neighboring property, sidewalk, roadway, or parking area is a violation of Section 17.195.200, and the director can order a water audit and recommend a fine set by the city council according to how large, frequent, or prolonged the violation is. Restrictions can be relaxed only where the runoff drains onto permeable surfacing or the adjacent hardscape is built to drain into the landscaping itself.
