Logan Flood Map: What to Check at Your Address

EcoFlow

In Logan, the house may remain dry while the road to it becomes impassable. A useful flood check therefore covers the whole lot, the building footprint and the routes you would use to leave. Begin with the address in Logan City Council’s Flood Portal, open the Property Flood Report, then look at nearby roads and creek crossings. The information is valuable for renters, buyers and current residents—but it is planning information, not a live picture of floodwater.

The main things to check

  • Confirm that the street address, suburb and lot are the property you actually want to assess.

  • Review every relevant source of flooding, including rivers, creeks and overland flow.

  • Remember that a 1% AEP event has a one-in-100 chance of being equalled or exceeded in each year.

  • Do not assume unshaded land is guaranteed to remain dry in every possible event.

  • When rain is falling, rely on current warnings and road advice—not an old saved report.

Finding your property on the Logan flood map

Start with the council’s portal

Open the official Logan Flood Portal and search for your property. The portal lets you inspect the flood information currently available for an address. A screenshot supplied with a property listing may be cropped, simplified or out of date, so it should not be your only source.

Search the address and open the report

Type in the street address, select the correct result, and double-check the suburb and lot details. Be especially careful with units, battle-axe blocks, recent subdivisions and neighbouring properties with near-identical addresses. Open the Property Flood Report for the selected lot and save a dated copy. That gives you a specific document to discuss with a property manager, selling agent, conveyancer or other adviser.

What does 1% AEP actually mean?

AEP means annual exceedance probability. A 1% AEP flood has a 1% chance of being equalled or exceeded in any given year. It is not a timetable, and two such events can occur close together. Read the legend for each map layer and note whether you are looking at a modelled scenario or the extent of a past event.

Check which version you are reading

As at 28 October 2026, Council had endorsed the proposed improvements to the Logan Flood Portal and Property Flood Reports on 14 October; that decision did not mean the revised maps and reports were already live. The related TLPI No. 1 2026, endorsed on 6 October, still required Queensland Government approval and subsequent Council adoption. Council expects the changes to take effect in early 2027, subject to those approvals. Its published timetable says the TLPI will commence and the portal changes will be released on the date specified in the adoption notice. Check Council’s flood-map updates and the report date before relying on a particular version.

Reading the report without jumping to conclusions

Study coverage varies across Logan. Work through the available information in layers: the land, the house, possible water depth or velocity, and the roads needed for access. One patch of colour on a map cannot answer all of those questions.

Is the shading on the house, the yard or the road?

Start with the map legend so you know which scenario is displayed. Then check whether the shading reaches the home itself, only part of the yard, or the road used to enter and leave. Those are different risks. If a mapped boundary sits close to the building, read the notes and seek clarification rather than treating the line as survey-level precision.

Look beyond the Logan and Albert rivers

Distance from the Logan or Albert River does not settle the issue. Local creeks, gullies and stormwater moving across the surface can also cause flooding. Check every source shown for the address, including overland flow. A low point or small watercourse near the property may be more relevant than the suburb’s broad reputation.

Check depth and access, where information is available

If the report provides modelled depth or velocity, check exactly where and under which scenario the figure applies. Water depth on a corner of the block is not automatically the depth inside the home. Pay equal attention to the route out; a creek crossing may become unsafe before the building is affected. Act early on official advice while a safe route is still available.

A model is not a live warning

A property report describes modelled possibilities. It cannot tell you whether a street is passable right now or when water will arrive during a particular storm. Neighbours’ memories can add useful context, but no one household has seen every possible event. Once severe weather begins, switch from planning documents to live warnings and road information.

Logan Disaster Dashboard

The Logan Disaster Dashboard brings together local warnings, road hazards and flood-camera information. Check more than your own street: the school run, a relative’s neighbourhood or the usual drive to work may be affected somewhere else. If a road is not shown as closed, that does not prove it is safe to use.

Logan Early Warning

Register for Logan Early Warning with up-to-date contact details. Alerts are available by SMS and email, with text-to-voice for landlines. The former Logan Early Warning app no longer sends notifications, so an old app on your phone is not enough. Review your account details and read the location and instructions in every alert.

Bureau of Meteorology warnings

Use the Bureau of Meteorology’s Queensland warnings page for current Flood Watches and Flood Warnings. Read the named catchment, affected locations and issue time rather than relying on a headline shared on social media. A BOM warning tracks developing conditions; a property report explains modelled exposure at an address. They serve different purposes.

QLDTraffic and local road updates

Check QLDTraffic before leaving, then continue to follow local directions as conditions change. Your street can be dry while a low-lying section or creek crossing farther along the route is underwater. Never drive, ride or walk through floodwater, and do not ignore a closure because Google Maps or another navigation app still shows the road.

Preparing for a blackout during wet weather

Decide where you would go, how the household would stay in contact and what must travel with you before thinking about backup power. A charged battery can keep essential devices running in a safe place; it is never a reason to remain after authorities tell you to leave.

Check outages with Energex

Use Energex’s Outage Finder to check known network outages in Logan; Council’s disaster dashboard also links to outage information. If yours is the only property without power, do not investigate wet switches or damaged wiring yourself. Keep at least 10 metres away from fallen powerlines and report them to Energex. Call Triple Zero (000) if life is in immediate danger.

Keep water and electrical equipment apart

If you have time and it is safe, move portable electrical gear to a high, dry location before water arrives. Never touch a wet switchboard, socket or appliance. Flood-affected wiring and fittings must be checked by a licensed electrical contractor before they are used again or reconnected. Renters should notify the property manager promptly, but evacuation instructions always come first.

Decide what really needs power

Prioritise phones, basic lighting and a battery radio. If anyone depends on medical equipment, prepare a specific backup and evacuation plan with their healthcare team, equipment supplier and electricity retailer. For ordinary devices, multiply watts by hours to estimate watt-hours, then allow for conversion losses. EcoFlow AU’s flood-preparation guide covers the broader household checklist.

Choose backup power around those essentials

Charge batteries while mains power is still available. When comparing EcoFlow AU portable power stations, look at both storage capacity in Wh and output in W, including the start-up surge of appliances such as a fridge. A 72-hour emergency-kit guide is useful for organising leads and essentials, but the label does not mean every power station will run your own device mix for three days.

Keep any portable power station dry, upright and ventilated, and connect only compatible appliances in line with the manual. Never plug its output into a household wall socket or use it to energise flood-damaged wiring. Runtime depends on the real load and whether safe recharging is available. If an evacuation order is issued, leave rather than spending time collecting or charging equipment.

Turn the map into a household plan

Turn the report into a short household plan: where you will go, which routes must be checked, who needs help and what leaves with you. Keep the dated report for reference, but return to Council, BOM and road updates whenever conditions change. The map improves awareness; acting early on current advice is what reduces risk.

Questions Logan households often ask

Can I get a report for a rental?

Yes. The public portal is available whether you own or rent. Check the exact address and lot, save the report, and raise questions about the building or access route with the property manager.

What if the house has never flooded?

A dry history is reassuring, but it is not a guarantee. Rainfall, development and flood behaviour can differ from past events. Consider the available modelled scenarios as well as local experience, and continue to follow official warnings.

Will the map change my insurance premium?

Council does not set insurance premiums. Each insurer assesses the address under its own model and policy terms. Ask specifically about flood cover, exclusions and the applicable excess; a Council mapping update does not automatically produce the same change in every policy or premium.

Can I check a vacant block?

Yes. Search the address or select the correct lot on the map. If you plan to build, use the report to frame questions for Council, your certifier and other advisers. The flood report is information, not development or building approval.

Will rooftop solar keep working in a blackout?

Usually not by itself. Most standard grid-connected solar systems shut down during a blackout for network safety. Backup operation depends on the inverter, battery and changeover arrangement installed at the property. Check the system documentation and ask the installer before relying on solar in an outage.

Who checks electrical equipment after a flood?

Have a licensed electrical contractor assess affected wiring and fixed equipment. Water-damaged appliances also require professional assessment; plugging one in to ‘see if it works’ is unsafe. If Energex has disconnected the premises, follow the required inspection and reconnection process.
