Summary

Temecula's Water Efficient Landscape Ordinance, Chapter 17.32 of the Municipal Code, requires recirculating systems for every water feature and mandates recycled water for decorative water features whenever a recycled water supply is available. The rule applies to new landscape projects of 500 square feet or more and rehabilitated landscapes of 2,500 square feet or more that need a building or landscape permit, plan check, or design review from Community Development.

O. Decorative Water Features. 1. Recirculating water systems shall be used for water features. 2. Where available, recycled water shall be used for decorative water features. 3. The surface area of a water feature shall be included in the high water use hydrozone area of the water budget calculation.

Full Breakdown

060(O) sets the decorative water feature rule inside the Water Efficient Landscape Design chapter: recirculating water systems are mandatory for any water feature, and where a recycled water supply is available, that supply must be used for decorative fountains, ponds, and similar features rather than potable water. 020. 0. 030 to new construction landscape projects of 500 square feet or more and rehabilitated landscape projects of 2,500 square feet or more that require a building or landscape permit, plan check, or design review. 060(P). 090 must be designed to accommodate a future conversion to nonpotable water in any area scheduled for it, meeting standards set by the city, the Regional Water Quality Control Board, the State Department of Health Services, Riverside County's health department, and the local reclaimed water purveyor.

Before a certificate of use and occupancy issues, the project's landscape architect must certify in a letter of completion that the irrigation system and water features were installed as approved. The chapter was last amended by Ordinance 2025-15 on November 18, 2025.

Violations & Fines

Community Development will not approve a landscape or building permit, or issue a certificate of use and occupancy, without a compliant water budget and a signed letter of completion from a licensed landscape architect confirming installed water features meet Section 17.32.060(O). Under Section 17.32.170(E), the city relies on local water purveyors to enforce ongoing compliance for existing landscapes, including tiered water rate structures, irrigation audits, and penalties for water waste on properties misusing potable water in a feature designed for recycled supply.

Frequently Asked Questions

Does Temecula require recycled water for backyard fountains?
Only decorative water features covered by the Water Efficient Landscape Ordinance, which applies to new landscape projects of 500 square feet or more and rehabilitated projects of 2,500 square feet or more needing a permit or design review. Where a recycled water supply is available, Section 17.32.060(O) requires that supply for the feature; smaller residential landscape work below those thresholds falls outside the chapter.
What counts as a decorative water feature under the code?
Section 17.32.020 defines water features as ponds, lakes, waterfalls, fountains, artificial streams, spas, and swimming pools where open water serves an aesthetic or recreational purpose. Their surface area is added to the high water use hydrozone in the project's water budget, and Section 17.32.060(O) requires a recirculating system regardless of whether recycled water is available.
Who enforces recycled water compliance after installation?
Section 17.32.170(E) puts ongoing enforcement on local water purveyors rather than city staff alone. The city coordinates with purveyors on tiered rate structures, irrigation audits, and penalties for water waste. Community Development handles compliance at the permit and certificate-of-completion stage before occupancy is granted.
Does recycled water use change how much water a project can apply?
Yes. Section 17.32.020 defines special landscape areas irrigated with recycled water as not subject to the tighter 0.55 residential or 0.45 nonresidential ET adjustment factor cap, allowing an ETAF up to 1.0 in the Maximum Applied Water Allowance formula, which lets those areas carry a larger water budget than ordinary landscape.
