Balboa Island and Little Balboa Island: what this part of Newport Beach is
Balboa Island sits inside Newport Bay, in the harbor. The city's zoning area map A-1 treats Balboa Island and Little Balboa Island as one area. Neighborhood boundaries are informal, so when you call, the street name tells the listener more than a map line does.
The island is man-made. According to the Visit Newport Beach history page, a channel was dredged in 1908 to 1909 and the sand and silt were piled onto a mudflat. It became part of Newport Beach in 1916, and early on it was described as little more than a sandbar that high tide often swallowed. That history is why the question of where the water came from comes before anything else.
The bulkhead
The same history page says the first wooden bulkhead went in during 1909, was partly replaced with cement in 1912 and was rebuilt in 1922. The present Bay Front bulkhead was completed in 1938. If your lot touches the harbor, that wall is part of how water does or does not reach your building.
Getting on and off
A ferry service began in 1919, and a concrete bridge opened in 1929 and was rebuilt in 1981. Tell the person on the phone how your street is reached, because access shapes how a drying job is planned.
Associations on the map
The city's community association map lists the Balboa Island Improvement Association and the Little Balboa Island Property Owners Association. If you rent or live in a shared building, find out who manages it before you call anyone else.
Two kinds of water
Plumbing water comes from a supply line, water heater, appliance or roof. Harbor water comes over a wall or up through a drain. The first is often clean when it starts, and the second is not. Say which one you suspect when you call.
Water is spreading on the island: what to do first
Start with the source. If it is a supply line, a water heater or a washer, close the shutoff for that fixture or the main water valve. Then call (949) 670-0939, describe the damage and the street, and ask what to do while you wait.
Cut power to wet rooms only when the panel is dry and reachable without standing in water. A gas smell, sparking outlets or water running through a light fixture mean you go outside and call 911 or the gas utility before anyone else. Keep children and pets out of wet rooms.
If the water is coming from the harbor, the street or a drain, do not wade into it. Water that has crossed a seawall or come up through a storm drain can carry sewage and debris, and that is work for professionals. Photograph from a dry spot, move valuables up off the floor and call.
Water inside on Balboa Island?
Call (949) 670-0939, describe the damage and the street, and say whether you think it came from a pipe or the harbor.
Getting the house ready before drying equipment goes in
Each step takes a few minutes and makes the first visit go further.
Shut off what you can
Close the main water valve or the fixture valve and leave it closed until the leak is repaired.
Photograph before you move anything
Take wide shots and close shots of the water line on walls, wet floors and damaged belongings. Add short videos of any water still moving.
Lift valuables and clear floors
Move rugs, electronics, books and small furniture to dry ground. Leave heavy pieces where they stand.
Describe access
Mention stairs, gates, narrow side yards, parking limits and any building access code. Tight access makes this a real planning question.
Tell your manager or association
Renters notify the landlord or property manager. Owners in a shared building notify the association or manager, who may have rules about repairs.
Keep wet materials in place
Do not tear out wet drywall or carpet before it has been photographed and read with a moisture meter.
What water damage on Balboa Island can look like
Two things are on the public record. The city's king tide advisory names Balboa Island among the low-lying harborfront neighborhoods where evening high tides may cause localized flooding. And the regional hazard-mitigation annex says rising ocean levels are causing flooding more often on Balboa Island and the Balboa Peninsula. Those are harbor-water facts. They say nothing about the pipes in your walls, which depend on your building.
King tide evenings
The city says crews install flood-protection gap boards on Balboa Island and run pumps. For owners next to the harbor, the city suggests seawall plugs and sandbags in vulnerable spots. Prefilled sandbags are at the City Corporation Yard on Superior Avenue, and unfilled sandbags are at city fire stations.
Stop-boards at the wall
A 2017 report in The Log described harbor water topping the seawall during king tides and storm surges. It said the city approved a concrete cap adding 9 inches, and that 3-foot gaps at public docks and street ends take stop-boards bolted in place during high tides. If your lot sits near a street end, keep dated photos of any water line.
When the water came from the bay
Harbor water is treated as Category 3, grossly contaminated, under the ANSI/IICRC S500 standard. Carpet, pad and lower drywall that it touched are usually removed, and the area is cleaned before drying starts. Do not attempt this yourself.
Pipes and appliances
A supply line, water heater, washer or dishwasher leak is plumbing water, not tidal water. How far it spreads depends on your building, so check whether the wet area sits over a slab, a crawl space or living space below, and say so on the call.
Rain through the envelope
Rain that gets in through a roof, window or door is storm water damage. Mark where it entered and photograph the stain before it dries.
Whatever the source, give the caller two details: where the water entered and whether it touched anything dirty.
How extraction and drying work in a waterfront home
Standing water comes out first. Extraction units and wet vacuums pull it from floors, then moisture meters read the walls, subfloor and baseboards to map where it traveled. A thermal imaging camera helps find wet areas behind surfaces. Anything that cannot dry, such as soaked carpet pad, comes out.
Then the drying equipment goes in. Air movers push dry air across surfaces and LGR dehumidifiers pull moisture out of the air. Readings are taken daily, and the equipment stays until the materials match a dry reference. The EPA says water-damaged areas and items should be dried within 24 to 48 hours to prevent mold growth, which is why the first day matters.
Ask what should stay closed during drying, since open windows work against the equipment. If harbor water was involved, ask how contaminated materials will be removed and how the area is cleaned. Mold is assessed after drying, and mold remediation is a separate service.
Documenting the loss and telling the right people
The California Department of Insurance says standard homeowners insurance does not cover flood damage. Flood coverage is a separate policy, such as the federal National Flood Insurance Program, and an NFIP policy generally takes effect 30 days after purchase. Harbor water over a seawall is a flood question and a broken pipe is a different one. Check your policy and ask your insurer which applies, and ask about deadlines.
Photos, short videos and the moisture readings taken during drying all help document the loss. Keep receipts and a list of damaged items. The state's consumer help line for disputes with an insurer is 1-800-927-4357, and The NFIP line for claims and policy questions is 1-800-638-6620.
For water surfacing in the street or from a city main, call the city's water and sewer emergencies line at (949) 644-3011. Check your water bill to see whether the City of Newport Beach or another district, such as Irvine Ranch Water District or Mesa Water District, supplies your address. Whether a repair needs a permit is a question for the city Building Division.
Services that fit Balboa Island water problems
Match the service to where the water came from.
Harbor water and flooding
When water comes from the bay or a storm surge, flood damage restoration covers extraction, removal of contaminated materials and drying.
Contaminated water
Water that came up a drain or carried sewage falls under sewage backup cleanup. Stay out of it and call.
Limiting the spread
Water mitigation is the first stage: stop the spread, remove what is wet and protect what is still dry.
Wet framing and subfloors
Floors and wall cavities that stay wet after the surface looks dry need structural drying.
Standing water right now
If water is standing in the home, ask about emergency water removal on the call.

Balboa Island is one part of Newport Beach, and the service area page lists the rest. If you own property elsewhere in the city, you can also see the pages for the Balboa Peninsula and Corona del Mar. Each page covers the water problems that fit that area.
Balboa Island Questions
Is emergency water removal available in Balboa Island?
Call (949) 670-0939, describe the damage and the street, and ask what to do while you wait. Hours and timing are not promised on this page. While you wait, close the water source, keep people out of wet rooms and take photos.
Who do I call about water in the street or a city main on the island?
The city's Utilities Department lists a water and sewer emergencies line at (949) 644-3011, with the Police Department line at (949) 644-3717 after hours. You can also use the city's Report a Problem page or the MYNB app. Call the restoration line for whatever got inside your building.
Does insurance cover harbor water that came over the seawall?
Flood damage sits outside a standard homeowners policy, and flood coverage is bought separately. Check your policy, ask your insurer which cause applies and ask about deadlines. Photos and moisture readings help document the loss.
What changes in the cleanup when the water came from the bay?
Harbor water is treated as Category 3 under the ANSI/IICRC S500 standard, so porous materials it touched are usually removed and surfaces are cleaned before drying. That is a job for professionals, not for a mop and a fan.
What do the king tide gap boards and sandbags mean for my property?
The city says it installs gap boards on Balboa Island and runs pumps, and it suggests seawall plugs and sandbags for harbor-front owners. Prefilled sandbags are at the City Corporation Yard on Superior Avenue. Your own wall and lot are your responsibility to check, so ask the city what applies to your address.
How do I find out whether my address is in a flood zone?
A zone for individual Balboa Island addresses is not verified here. Check the city's flood zones map and the FEMA Flood Map Service Center for your address, and ask the city Building Division about elevation certificates.
