St. Augustine Beach water outage set for single-customer meter work

St. Johns County Utility Department will shut off water service to 401 A1A Beach Boulevard in St. Augustine Beach for six hours on November 3 to replace a master meter, followed by a mandatory precautionary boil-water notice that will remain in effect for at least two days.

The planned outage will run from 9 a. m. to 3 p. m. and affects one customer at the A1A Beach Boulevard address, according to a public notice posted by St. Johns County. The county notified the impacted customer by door tag.

What's happening

St. Johns County Utility Department scheduled the outage to replace the master meter serving 401 A1A Beach Boulevard. The work is set to begin at 9 a. m. on November 3, 2026, and conclude by 3 p. m. the same day.

The county identified the primary cause of the outage as "master meter replacement. " One customer will be impacted by the service interruption, and the utility department used door tags to provide advance notification.

Following the outage, a precautionary boil-water notice will take effect for the address. Under the notice, all water used for drinking, cooking, making ice, brushing teeth, or washing dishes must be boiled at a rolling boil for one minute. Bottled water may be used as an alternative.

The boil-water notice will remain in place until laboratory tests confirm the water is safe to drink and a retraction notice is posted—a process that typically requires a minimum of two days. The county will post door tags again once the notice is rescinded.

Residents may call the county's Boil Water Notice Hotline at (904) 209-2731 for updated information on when the precautionary notice is lifted.

Why master meters require boil-water notices

Master meters are large-scale water meters that measure consumption for entire buildings, complexes, or multi-unit properties before water flows to individual units or sub-meters. When a utility replaces a master meter, the work requires shutting down the water main, opening the system to perform the swap, and then re-pressurizing the line.

Any time a pressurized water distribution system is opened or depressurized, Florida Department of Health rules and industry best practices require utilities to issue a precautionary boil-water notice. The concern is that during the work, contaminants could enter the system through the open connection or low pressure could allow groundwater or surface water to infiltrate the pipe.

The notice remains in effect until the utility collects water samples from the affected section of the system and a certified laboratory tests them for coliform bacteria, which serve as an indicator of potential contamination. Florida rules typically require at least 24 hours of incubation time for the bacterial cultures, meaning even expedited test results take a minimum of one to two days.

Once lab results confirm no contamination, the utility posts a retraction notice and customers may resume normal water use. For a single-customer outage such as this one, the process is straightforward: the county will deliver door tags to notify the customer when the all-clear is given.

What the work signals for coastal water systems

Master-meter replacements are a routine but essential element of water-system maintenance, particularly in aging coastal communities where salt air and humidity accelerate corrosion of metal components. St. Augustine Beach, one of St. Johns County's oldest beach communities, includes a mix of mid-century homes, small apartment buildings, and newer mixed-use developments along the A1A corridor.

The address affected by the November 3 outage—401 A1A Beach Boulevard—sits on the primary beachside artery, a stretch that has seen steady redevelopment and infill construction in recent years as property owners renovate older motels, shops, and residential buildings. Master meters are common at older multifamily and commercial properties, where the building owner pays the utility and sub-meters or allocates costs to tenants.

Replacing a master meter can be driven by age, calibration drift, or the need to upgrade to newer "smart" metering technology that allows remote readings and leak detection. St. Johns County, like many Florida utilities, has been gradually modernizing its metering infrastructure to improve billing accuracy and identify system leaks more quickly.

For the single customer affected, the outage and boil-water period represent a minor inconvenience—six hours without running water and two days of boiling or buying bottled water. But the work is part of a broader capital-maintenance cycle that utilities across Northeast Florida must manage as the region's population grows and development intensifies along the coast.

St. Johns County Utility Department serves unincorporated areas of the county, including the beaches, Ponte Vedra, and parts of the SR 16 and CR 210 growth corridors. The department has been expanding capacity and upgrading aging lines to keep pace with one of Florida's fastest-growing counties, where new master-planned communities such as Nocatee and SilverLeaf are adding thousands of rooftops each year.

Impact on nearby businesses and residents

The A1A Beach Boulevard corridor is a mixed commercial and residential zone, home to beach shops, restaurants, vacation rentals, and year-round residents. A six-hour daytime outage on a Monday will require any affected business or residential units at the address to plan ahead: restaurants would need to stock bottled water for food prep and dishwashing, and any overnight guests or tenants would need advance notice to fill containers for flushing toilets and washing hands.

Because the outage affects only one customer—likely a single building or property with a master meter serving multiple units or tenants—the broader neighborhood will not experience service interruptions. Neighboring properties along A1A Beach Boulevard will maintain normal water service throughout the day.

The two-day boil-water period that follows poses a greater operational challenge for any food-service business at the address. Under Florida Department of Business and Professional Regulation rules, restaurants and food establishments must use potable water for all food contact, ice production, and dishwashing. During a boil-water notice, operators must either boil all water or switch to bottled water, adding labor and cost.

For residential tenants, the inconvenience is modest but requires attention: boiling water for coffee, cooking, and tooth-brushing, and avoiding tap water for drinking until the all-clear. Showers and laundry are generally safe during a precautionary notice, since the concern is ingestion, not skin contact.

What happens next

The six-hour outage is scheduled to run from 9 a. m. to 3 p. m. on November 3, 2026. St. Johns County Utility Department crews will replace the master meter during that window and restore service by mid-afternoon.

Once water service resumes, the precautionary boil-water notice takes effect immediately. County staff will collect water samples from the system and submit them to a certified laboratory for coliform bacteria testing. Results typically take a minimum of 24 to 48 hours.

If lab results show no contamination, the county will post a door-tag retraction notice at 401 A1A Beach Boulevard, lifting the boil-water advisory. Customers may call the Boil Water Notice Hotline at (904) 209-2731 to check the status of the notice before the door tag is delivered.

The work is one of hundreds of routine infrastructure projects St. Johns County manages each year to maintain a water system serving a rapidly growing population. As coastal Northeast Florida continues to attract new residents and redevelopment, utilities face the dual challenge of expanding service to new areas while replacing aging pipes, meters, and treatment equipment in established neighborhoods—a balancing act that plays out one planned outage at a time.
