El Cajon's Water Use Rules: The Rules That Matter
Every city handles water use rules a little differently. In El Cajon, California, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Turf Replacement Rebates
Non-residential landscape projects in El Cajon can't put turf grass on more than 25 percent of the total landscaped area, under Municipal Code Section 17.195.150(E). Sports fields, parks, golf courses, and cemeteries are exempt, and low-volume or subsurface irrigation is mandatory on narrow strips and steep slopes.
Key details: Turf cap, non-residential: 25% of landscaped area. Exempt uses: Sports fields, parks, golf courses, cemeteries. Turf banned in: Medians and parking lot islands. Governing section: § 17.195.150. Review path: Landscape Documentation Package, § 17.195.240.
A non-residential project that installs turf on more than 25 percent of its landscaped area, or that places turf in a median, parking lot island, or a strip narrower than six feet, fails to meet Section 17.195.150 and can be held up at the Landscape Documentation Package or certificate-of-completion stage under Sections 17.195.240 and 17.195.330 until the design is corrected.
Leak Reporting Duty
El Cajon treats water that escapes, flows or seeps from a property connected to the public water system as proof of illegal water waste under Municipal Code Section 13.04.020. The person in possession or control of the leaking property is presumed responsible for the violation, which the city can abate as a public nuisance.
Key details: Trigger: Water escaping, flowing or seeping from property. Evidence standard: Prima facie evidence, no intent required. Responsible party: Person in possession, control or ownership. Classification: Public nuisance, abatable by city.
Letting water escape, flow or seep from a connected property is prima facie evidence of unlawful water waste under Sections 13.04.010 and 13.04.020, and the person in possession, control or ownership of the property is presumed responsible under Section 13.04.030. Because the violation is also a public nuisance under Section 13.04.040, the city can abate it directly under the nuisance-abatement procedures in Chapter 1.16, potentially charging the cost to the property owner.
Recycled Water Rules
If recycled water runs in the street in front of a covered property, El Cajon requires the project to use it for irrigation, not potable water, under Municipal Code Section 17.195.190. Recycled-water users must install a purple-piped dual distribution system and get credit toward their water budget through a 1.0 evapotranspiration adjustment factor.
Key details: Trigger: Recycled water available in street frontage. Requirement: Use recycled water for irrigation. Pipe color: Purple, dual distribution system. Water credit: ETAF of 1.0. Governing section: § 17.195.190.
A covered project that fails to connect to available recycled water for irrigation, or that pipes it through a standard, non-purple distribution system, does not meet Section 17.195.190 and can be denied approval of its Landscape Documentation Package or certificate of completion under Sections 17.195.240 and 17.195.330 until corrected.
The Bottom Line
El Cajon's water use rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming El Cajon is broadly strict or permissive.
