Allowed Watering Hours
Flagstaff sits at 7,000 ft elevation in northern Arizona and operates under a snowpack-driven water framework that is different from the Phoenix metro Tier 2 / SRP / CAP system. The city draws from Upper Lake Mary, the Inner Basin springs of the San Francisco Peaks, the Lake Mary and Woody Mountain well fields, and in-city wells. Following a historically dry winter, Upper Lake Mary entered the 2026 season at very low levels and Flagstaff has shifted toward greater reliance on its groundwater wells. As of this update, the city has not declared a mandatory drought stage, voluntary conservation guidance applies. Verify the current status with City of Flagstaff Utilities at flagstaff.az.gov before assuming any specific schedule.
Still Allowed

Fines & Enforcement
Verify with City of Flagstaff Utilities

Citations begin Spring 2026 watch, verify current status🏠 HOA Rules During Restrictions
Arizona Revised Statute §33-1808 protects every Arizona homeowner's right to install desert-adapted xeriscape regardless of HOA covenants, this applies year-round, not only during droughts. ARS §33-1902 prohibits HOA fines for brown or dormant lawns during a declared water shortage. Flagstaff HOAs cannot mandate cool-season turf or block native high-desert plantings.
If your homeowners association sends a violation notice for a dormant or brown lawn during the current restriction period, respond in writing citing the applicable law and include a copy of the City of Flagstaff Utilities's current restriction order. Most HOAs will rescind the notice once they are made aware of the legal protections in place. If the issue persists, contact your county’s code enforcement division for assistance.
Why These Restrictions Exist
Flagstaff is structurally different from the Phoenix-area cities. At 7,000 ft elevation in the San Francisco Peaks, the city is NOT served by Salt River Project (SRP) and is NOT subject to Colorado River Tier 2 cuts via the Central Arizona Project (CAP) the way Phoenix-area cities are. Flagstaff's water comes from a snowpack-driven mix of Upper Lake Mary surface water, springs in the Inner Basin of the San Francisco Peaks, and groundwater from the Lake Mary, Woody Mountain, and in-city well fields. The 2025–26 winter was historically dry, leaving Upper Lake Mary very low and increasing the city's dependence on groundwater wells for the 2026 season. The Coconino Plateau aquifer that supplies Flagstaff is not subject to the same Active Management Area regulation as the Phoenix and Tucson AMAs, which makes long-term sustainability a separate policy question for the city. Verify any current mandatory restrictions directly with City of Flagstaff Utilities, this page reflects voluntary conservation framing as of the publication date.
This deficit has accumulated over the current water year and represents a significant departure from historical averages for the Flagstaff area. Water supply reservoirs and aquifer levels are well below seasonal targets, necessitating mandatory conservation measures.
How to Keep Your Lawn Alive During Flagstaff Water Restrictions
11 tips tailored for Flagstaff homeowners during Voluntary Conservation - Snowpack-Driven Watch restrictions.
Flagstaff is NOT under Phoenix Stage 2 / SRP / CAP rules, different water source, different framework. Verify your local utility status before assuming a schedule.
Kentucky Bluegrass and tall fescue are the practical lawn grasses at 7,000 ft elevation, both can survive periodic dormancy and recover when monsoon rains arrive.
Water deeply and infrequently, Flagstaff's clay-loam soils benefit from cycle-and-soak (5 minutes on, 20-minute pause, 5 minutes on) more than continuous spray.
Mow at 3–3.5 inches in summer to shade the crown and reduce evaporation; mountain UV at 7,000 ft accelerates surface drying.
Replace ornamental turf with native high-desert species: Apache Plume, Rabbitbrush, Penstemon, Native Yarrow, all thrive on Coconino Plateau rainfall alone after establishment.
Mulch deeply with bark or wood chips on ornamental beds, at Flagstaff's elevation, evaporation rates are lower than in the Phoenix metro and organic mulches last longer.
Take advantage of monsoon July–September: skip the next scheduled irrigation cycle after any 0.25" rainfall, deep monsoon storms reset soil moisture for 7–10 days.
Fix leaks within 48 hours, Flagstaff's freeze-thaw cycle in shoulder seasons can crack older valves and PVC; spring is the highest-risk window.
Harvest snowmelt and rainwater into seasonal cisterns for landscape use, Flagstaff's 22-inch annual precipitation supports modest passive harvesting.
Track monthly use at flagstaff.az.gov, Flagstaff Utilities encourages 10% reductions during voluntary conservation watches to delay any mandatory stage activation.
Verify any current mandatory restrictions or rebates directly with City of Flagstaff Utilities at 928-779-7685 before committing to large landscape changes.
