Summary

Vista does not mandate recycled water for landscaping, but Chapter 18.56 encourages it and rewards it: Section 18.56.040 classifies any landscape irrigated with recycled/reclaimed water as a Special Landscaped Area, giving it a larger share of the city's Maximum Applied Water Allowance formula.

Recycled/reclaimed water means water obtained from the treatment of domestic water waste which is suitable for direct beneficial use or a controlled use that otherwise would not occur, and also meets the highest level in conformance with the California Code of Regulations, Title 22, Division 4, Chapter 3 (use of recycled water for irrigation and for impoundments), currently sections 60304 and 60305.

Full Breakdown

Vista's landscaping code treats recycled water as a conservation tool rather than a mandate. 56, the Water Efficient Landscaping ordinance, to encourage the use, when available, of tertiary treated recycled/reclaimed water. 040 defines recycled/reclaimed water as water obtained from the treatment of domestic water waste that is suitable for direct beneficial use or a controlled use that otherwise would not occur, and it ties the standard to the California Code of Regulations, Title 22, Division 4, Chapter 3, specifically sections 60304 and 60305, governing recycled water used for irrigation and impoundments.

The same section folds any landscape irrigated with recycled/reclaimed water into the ordinance's Special Landscaped Area (SLA) category, alongside community gardens and active recreation turf. 62)[(ETAF x LA) + ((1-ETAF) x SLA)], grants SLA square footage the full (1-ETAF) share of the water budget rather than the reduced ETAF-adjusted share applied to ordinary landscape area, so a project that irrigates with recycled water carries a larger water allowance under the same citywide formula. 050 for qualifying projects of 500 square feet or more must reflect that water source when the calculation is submitted for City review.

Violations & Fines

Because recycled water use here is a design classification inside the water budget calculation rather than a standalone permit, problems arise when a project overstates its Special Landscaped Area or submits an inaccurate Landscape Documentation Package. Chapter 18.82 makes any violation of Title 18 a misdemeanor enforced by the City Manager's designee and the County Sheriff under Section 18.82.010, penalized per Section 1.16.010, with each day of a continuing violation a separate offense under Section 18.82.030.

Frequently Asked Questions

Does Vista require developers to use recycled water for landscaping?
No. Section 18.56.010 only lists encouraging tertiary treated recycled/reclaimed water use, when available, as one purpose of the Water Efficient Landscaping ordinance; the chapter does not mandate a recycled water hookup for any project.
What counts as recycled water under Vista's code?
Section 18.56.040 defines recycled/reclaimed water as treated domestic wastewater suitable for direct beneficial or controlled use that meets the state's Title 22 standard, specifically California Code of Regulations sections 60304 and 60305 governing recycled water used for irrigation and impoundments.
Does using recycled water change my landscape's water budget?
Yes. Section 18.56.040 classifies land irrigated with recycled/reclaimed water as a Special Landscaped Area, which receives the full (1-ETAF) share of the Maximum Applied Water Allowance formula rather than the reduced share applied to ordinary landscaped area, effectively raising the allowed water use total.
