Planning commission forwards water-efficient landscaping and turf restrictions to council

The Centerville City Planning Commission unanimously voted March 11 to forward a set of zoning-code amendments to the city council that would restrict turf in park strips, impose width- and area-based turf limits, and establish a consolidated water-efficient landscaping standard intended to make residents eligible for water-conservation incentive programs.

Staff explained the revised draft grew from discussions beginning in mid-2025 and was prepared in coordination with the Weaver Basin Water Conservancy District and state reviewers. Mr. Eggot summarized the history and scope of the proposal; staff member Lisa led a page-by-page review of the 16-page draft, saying the package represents “a 180” from previous lawn-first standards to a water-efficient approach that separates commercial landscaping rules from single-family rules.

Key changes the commission discussed include: prohibiting lawn in park strips (with a limited exception where no sidewalk exists), banning turf in areas narrower than 8 feet, limiting single-family front/side-yard turf to no more than 35% of landscaped area, capping total turf at 15% for non-single-family developments, and setting nonconforming triggers for new development (commercial thresholds tied to existing nonconformity code and single-family triggers tied to demolition/rebuild or expansions exceeding roughly 50% of structure size). Lisa noted many technical, recommended irrigation and planting practices were drawn from Weaver Basin guidance (for example, encouraging low-volume drip systems and a target of about 35% plant foliage coverage at maturity) and that some items remain recommendations while turf prohibitions are mandatory.

Staff said it had shared the draft with Weaver Basin; Mr. Eggot reported that David Rice reviewed the draft with the state and “said, ‘You’re good to go,’” which staff took as confirmation the proposal aligns with program expectations. Commissioners discussed a local difference with Weaver Basin: Centerville’s streets department will continue to prohibit rock, bark, mulch and similar materials in park strips for stormwater/street-maintenance reasons, so that part of Weaver Basin’s program cannot be implemented in park strips within Centerville.

A commissioner moved to forward a positive recommendation to city council and to grant staff scrivener authority to make non-substantive edits (including the three minor clarifications staff listed); the motion was seconded and passed unanimously. Staff said adoption would make residents eligible for local incentive programs but would not obligate immediate removal of existing lawns except where the code’s defined development triggers apply. The item will appear on a future city-council agenda for final action.
