Summary
Vista's Water Efficient Landscape Ordinance goes beyond the state model: Section 18.56.130 requires drip irrigation in every landscaped area except slopes graded 4:1 or steeper, and confines turf to spaces with recreation utility or that function as bio-swales or bio-retention areas.
This Landscape Manual and the Water Efficient Landscape Ordinance (Chapter 18.56 of the Vista Development Code) meets or exceeds the California Department of Water Resources Model Water Efficient Landscape Ordinance by making the Plant Factors and Irrigation Efficiency more restrictive; by requiring drip irrigation in all landscaped areas except slopes (grades 4:1 or steeper) and turf areas, and by restricting the use of turf to areas that have recreation utility or serve as bio-swales/bio-retention areas.
Full Breakdown
56. The section states that Vista's Landscape Manual and Water Efficient Landscape Ordinance exceed the state model by making Plant Factors and Irrigation Efficiency standards more restrictive, by requiring drip irrigation in all landscaped areas except slopes (grades 4:1 or steeper) and turf areas, and by restricting turf to areas that have recreation utility or that serve as bio-swales or bio-retention areas. In practice, ordinary front and side yards on a covered project cannot be planted in lawn merely for appearance; turf is confined to spaces used for active recreation, such as a private play area, or to areas functioning as stormwater bio-retention.
090. 130 also states this local approach substitutes for some state model requirements, waiving the installation of flow sensors, master valves and separate irrigation water meters, and the requirement to perform landscape irrigation audits, on single-family residential projects. 060.
Violations & Fines
A landscape plan that puts turf outside a recreation or bio-retention area, or that uses overhead spray where drip is required, fails the Landscape Documentation Package review under Section 18.56.080 and cannot receive final approval. Beyond permit denial, Chapter 18.82 makes any Title 18 violation a misdemeanor enforced by the City Manager's designee and the County Sheriff under Section 18.82.010, with penalties set by Section 1.16.010 and each day of noncompliance a separate offense under Section 18.82.030.
