Flower Mound, TX Landscaping Rules: Water Restrictions (2026)

Flower Mound's water conservation ordinance establishes a permanent twice-per-week landscape irrigation schedule. Watering days are assigned by address (odd-numbered addresses on designated days, even-numbered on alternating days). Irrigation is prohibited between 10 AM and 6 PM from April through October to minimize evaporation. The town receives its water supply from the Upper Trinity Regional Water District and coordinates drought response stages accordingly. Stage 1 restricts watering to once per week. Stage 2 prohibits all automatic irrigation and limits hand-watering. Stage 3 bans virtually all outdoor water use. Stage 4 is an emergency rationing level. Newly installed sod and landscaping may receive a temporary variance for establishment watering with an approved irrigation plan. Rain and freeze sensors are required on all automatic irrigation systems. Flower Mound's drought-prone Cross Timbers ecology and clay soils make efficient irrigation critical; foundation watering with soaker hoses is exempt from most restrictions to prevent structural damage. Code Enforcement issues citations for visible waste, runoff onto streets, and watering during prohibited hours.
