Full Breakdown
LMMC § 14.29.140 sets the operative turf rules inside the city's Water Efficient Landscape Regulations. Only low volume or subsurface irrigation may water turf on a slope steeper than twenty-five percent grade where the toe meets impermeable hardscape, or wherever a landscaped area is narrower than six feet in any dimension. On commercial, industrial, institutional or multi-family projects, turf is barred outright on center island median strips and parking lot islands. Ball fields, parks, golf courses, cemeteries and similar facilities must confine turf to the portions actually needed for operation, and no turf is allowed anywhere it cannot be efficiently irrigated without runoff or overspray.
These rules attach to any project needing a building or discretionary permit with 2,500 square feet or more of landscaped area (commercial, industrial, institutional, multi-family, or developer-installed residential common areas), a public agency project of the same size, or a new single-family home with 5,000 square feet or more of homeowner-provided landscaping, per LMMC § 14.29.030. The community development director administers and enforces the chapter under LMMC § 14.29.040 and reviews the landscape documentation package required by § 14.29.050, including planting and irrigation plans, before any building or discretionary permit issues.
Violations & Fines
The community development director enforces Chapter 14.29 under LMMC § 14.29.040. A landscape plan that puts turf on a prohibited median, parking island, narrow strip or steep slope fails review of the landscape documentation package required by § 14.29.050, and the city withholds the building or discretionary permit until the plan is corrected. There is no separate turf fine; enforcement runs entirely through the permit and plan-approval process.
