Alpharetta GA Water Restrictions 2026

Current water restrictions in Alpharetta, Georgia

Alpharetta is operating under Drought Response Level 1 declared by the Georgia Environmental Protection Division (EPD) on April 27, 2026, layered on top of the permanent year-round restrictions imposed by the Georgia Water Stewardship Act of 2010. Outdoor irrigation is allowed only between 4 p.m. and 10 a.m., every day, year-round.

Alpharetta is the hub of Georgia's technology corridor in north Fulton County. The city is anchored by the GA-400 corridor, lined by office parks and corporate campuses that house hundreds of technology, financial-services, and professional-services companies. The city's identity in the 2020s revolves around three things: tech employers, the Avalon mixed-use development at GA-400 and Old Milton Parkway, and a residential population that runs higher-income than most metro Atlanta cities. Population is approximately 67,000.

The water-management challenge in Alpharetta has two distinctive features. First, extensive commercial landscaping at office parks along North Point Parkway, Windward Parkway, and the GA-400 corridor consumes substantial water. Office-park landscapes — manicured lawns, decorative shrub beds, large entry features — are subject to the same Water Stewardship Act 4 p.m.–10 a.m. window as residential properties, but the per-property water consumption is much higher.

Second, Alpharetta's rapid office and residential growth over the past two decades has added significant impervious surface — buildings, parking lots, roads — that reduces natural groundwater recharge. Stormwater that historically infiltrated the soil and slowly recharged the surficial aquifer now runs off into storm drains and out of the watershed. The cumulative effect is a hydrologic regime where rainfall produces faster, peakier runoff and less sustained groundwater recharge — a structural challenge that affects all developing North Atlanta cities.

Water is supplied by Fulton County Department of Water Resources, drawing from the Chattahoochee River via the same supply chain used by Sandy Springs, Roswell, and Johns Creek.

Watering schedule and allowed hours

Hand watering with a hose fitted with a shut-off nozzle is permitted any time. Drip and microirrigation for non-turf plantings are typically permitted outside the closed midday window.

• Office park landscaping (North Point, Avalon, GA-400 corridor): commercial schedule, also restricted to 4 p.m.–10 a.m.
• Avalon mixed-use complex: commercial landscape under the same window.
• HOA common areas: commercial schedule.
• New sod and seed: establishment exemptions through Fulton County Water Resources.

What happens if you violate restrictions in Alpharetta?

Alpharetta enforces through Code Enforcement and Fulton County Water Resources:

• First violation: a written warning.
• Second and subsequent violations: escalating civil fines.
• Persistent violators: service-restriction action available.

To report a violation, call Fulton County Water Resources at 404-612-8000.

Other outdoor water rules

• Watering during measurable rain: prohibited. Rain sensors required.
• Excessive runoff: water sheeting onto streets, sidewalks, or storm drains is a violation regardless of time. Particularly important given Alpharetta's impervious-surface concerns.
• Pressure washing: permitted only for paint, sealant, repair, or required for health and safety.
• Decorative fountains: must recirculate or be drained.

Where Alpharetta's water comes from — and the impervious-surface problem

Alpharetta water comes from the Chattahoochee River, supplied by Fulton County. The supply chain mirrors other north Fulton cities: Lake Lanier reservoir storage upstream, Buford Dam releases, Chattahoochee River flow, Atlanta-Fulton intake, treatment, and distribution.

The local hydrology is shaped by Alpharetta's development pattern. Big Creek flows through the city and is the main tributary draining the area; the creek joins the Chattahoochee just east of the city. Big Creek Greenway follows the creek through Alpharetta and is one of the city's premier recreational amenities. The greenway and adjacent floodplain provide some natural stormwater infiltration, but the overall watershed has been substantially urbanized over the past 30 years.

The impervious-surface problem is a structural concern across all of metro Atlanta's growth corridors. Roads, parking lots, building footprints, and other hard surfaces don't allow rainfall to soak into the ground. Instead, water runs off into storm drains and out of the watershed quickly. Compared to a forested or rural landscape:

• Less groundwater recharge. Surficial aquifers don't replenish as effectively.
• Higher peak stormwater flows. Heavy rainfall produces faster, more intense runoff.
• Lower sustained baseflow. Streams and creeks have less flow between rain events.
• More stormwater pollution. Runoff carries oils, fertilizers, and pesticides directly into waterways.

Alpharetta has invested in green-infrastructure stormwater management — rain gardens, bioswales, permeable paving — particularly in newer commercial developments like Avalon. These features partially offset the impervious-surface impact but don't fully compensate for the cumulative effect of decades of urban growth.

Brown lawn protections in Georgia

OCGA § 44-3-235 prohibits HOAs from enforcing rules that conflict with state law. Alpharetta's many HOA-governed neighborhoods cannot legally require watering during the 10 a.m.–4 p.m. closed window or penalize drought-dormant lawns.

Sample HOA response:

"Dear [HOA Board], the Georgia Water Stewardship Act and EPD Drought Response Level 1 restrict outdoor irrigation to 4 p.m.–10 a.m. year-round. Under OCGA § 44-3-235, the Association may not enforce rules that conflict with state law. Please withdraw the violation. Sincerely, [Your name]"

Lawn care during Level 1

Alpharetta lies in USDA Hardiness Zone 8a. Common turf options:

Mow on the high end. Bermuda and Zoysia retain moisture better at the high end of their recommended mow ranges.

Skip summer fertilizer. Fertilizer pushes growth that the limited evening irrigation cannot support.

Mulch beds heavily. Two to three inches of bark or pine straw mulch.

Brown is not dead. Bermuda is built for dormancy and recovers reliably with rainfall.

Common questions about Alpharetta water restrictions

What time can I water in Alpharetta?

Only between 4 p.m. and 10 a.m. Watering between 10 a.m. and 4 p.m. is a violation of the Georgia Water Stewardship Act.

What about commercial landscape at Avalon and the office parks?

Commercial properties — including Avalon mixed-use, office parks at North Point, and other large landscape installations along the GA-400 corridor — operate under the same Water Stewardship Act 4 p.m.–10 a.m. window as residential. Major commercial properties typically use professional landscape contractors who comply; if you observe noncompliance, it is reportable.

How does Alpharetta's growth affect water?

Decades of office and residential growth have added substantial impervious surface, reducing groundwater recharge and producing peakier stormwater runoff. The cumulative effect is a hydrologic regime where rainfall produces faster runoff and less sustained baseflow. Newer developments incorporate green-infrastructure features (rain gardens, permeable paving) that partially offset the impact but don't fully compensate.

Where does Big Creek go?

Big Creek flows through Alpharetta and joins the Chattahoochee just east of the city. The Big Creek Greenway follows the creek and provides recreational amenity and partial floodplain protection. Big Creek is not a municipal water source — Alpharetta draws from the Chattahoochee through Fulton County's system — but is part of the local hydrology that ultimately feeds the river.

Can my HOA require my lawn to be green?

Not when doing so would require violating state law. The Water Stewardship Act prohibits midday irrigation; OCGA § 44-3-235 prevents HOAs from enforcing rules that conflict with state law.

What if I have a smart irrigation controller?

Smart controllers must be programmed to comply with the 4 p.m.–10 a.m. window and to skip cycles after measurable rain. Smart controllers don't exempt the property from the Water Stewardship Act — they're a tool for compliance.

How long will Level 1 last?

Until EPD rescinds. The 4 p.m.–10 a.m. permanent rule does not lift.

What days can I water my lawn in Alpharetta?

Any day — 4pm-10am only Hand watering with a shut-off nozzle is typically allowed any day during permitted hours.

What are the fines for watering violations in Alpharetta?

First offense: Written warning. Repeat violations: Escalating fines. Contact Fulton County Department of Water Resources for the full enforcement schedule.

When will water restrictions end in Alpharetta?

Current Level 1 Drought Response + Year-Round Water Stewardship Act restrictions are in effect through Permanent + Level 1 until EPD rescinds. Monitor https://www.fultoncountyga.gov/water for the latest status.

Can I hand water during Alpharetta water restrictions?

Yes. Hand watering with a hose fitted with a shut-off nozzle is generally allowed on any day during permitted hours. Drip irrigation and soaker hoses are also typically exempt from the day-of-week schedule. Confirm specifics with Fulton County Department of Water Resources.

How do I report a water waste violation in Alpharetta?
