To view Natural Hazard mapping layers for bushfire, flood and storm tides, or landslides visit the Redlands Coast Disaster Dashboard.
Current mapping indicates that Wellington Point has a few scattered high bushfire hazard areas. The largest section is adjacent to Hilliards Park Drive. Another large section of high bushfire hazard areas can be found adjacent to Ormiston College, at the western end of Dundas Street. There is also high bushfire hazard surrounding land in Nelson Road, bordering Belford Drive.
Properties that are adjacent to bushland areas may be at risk of ember attack should there be a bushfire in the vicinity. During a wildfire, embers can travel up to 3 km in front of a fire line which means residents need to be vigilant and be prepared. For more information about bushfire preparedness and what to do during a bushfire, visit the Queensland Rural Fire Service website to create your Bushfire Survival Plan – PREPARE.ACT.SURVIVE.
Redland City Council employs a range of fire mitigation strategies to reduce the risk of bushfire in the area. These strategies include hazard reduction burning (back burns), fire breaks and weed management. Redland City Council works with its Local Disaster Management Group partners to undertake fire mitigation activities around the city.
Flood Prone, Storm Tide
Current flood prone, storm tide mapping indicates that Wellington Point has a number of areas susceptible to flooding from both tidal inundation and flash flooding, resulting from heavy rainfall events. Tidal inundation resulting from a storm tide event will have greatest impact on properties around Sovereign Lake and Allan Day Drive.
It is possible that tidal inundation would push inland far enough to surround the Redlands Sports Club and cause flooding to the sports fields along Birkdale Road. This section of Birkdale Road is also susceptible to flash flooding during heavy rainfall events and is identified on the list of roads known to be impacted by localised flooding. If Birkdale Road is cut due to flooding, it would prevent access from Wellington Point (to the east) to the Wellington Point High School, which is an Evacuation Centre.
Other areas of tidal inundation around Wellington Point include the Wellington Point Reserve, the coastline areas of the Wellington Point peninsula and a large area to the east of O’Connell Parade and Duke Street which is the mouth of Hilliard’s Creek which is mainly marsh land with no residential development. Hilliard’s Creek is also susceptible to flash flooding which can extend from the mouth of the creek in Ormiston, across the railway line at the end of Sturgeon Street, around Ormiston College and continue as far inland as Finucane Road, Cleveland.
Current mapping shows that the landslide hazard risk in Wellington Point is confined primarily to the northern peninsula areas of Main Street. This area has a low to medium landslide hazard and during Ex-Tropical Cyclone Oswald in 2013 experienced a small landslide that limited road access to the area. This peninsula area is accessed via one road – Main Street. Therefore, if a heavy rainfall event causes a landslide that cuts Main Street, the residential community to the north will become isolated.
These areas have a significant level of residential development and structures built within the area would need to comply with the requirements of the Redland Planning Scheme which, through the Landslide Hazard Overlay attempts to mitigate the impacts of the landslide hazard by requiring more robust engineering for developments built within the identified landslide hazard areas. It is important for engineers and geologists to evaluate slope stability and any landslide threat during development assessments so that effective and timely remedial measures can be implemented.
Critical infrastructure at the time of a disaster event includes utilities such as power, water, sewerage, telecommunications, gas, road and rail networks. Impacts of a disaster on these services may have far-reaching long-term affects for mainland communities.
The vast majority of Wellington Point is connected to the sewer network which links into the Thorneside Sewerage Treatment Plant located off Quarry Road. Current hazard mapping indicates that the Thorneside Sewerage Treatment Plant may experience impacts from tidal inundation during an extreme storm tide event.
The small number of acreage properties that are not connected to the sewer network rely on a mix of gravity-fed septic systems and on-site sewerage treatment plants located on the properties to manage the wastewater. The on-site sewerage treatment plants require electricity to function, therefore it is recommended that these systems have a back-up generator to cope with extended periods of power outages which can occur during severe weather events.
Wellington Point receives its water supply from the Alexandra Hills Reservoir located at Hilltop Circuit, Alexandra Hills. The Alexandra Hills Reservoir services the Redland City’s northern suburbs via a pipeline network that is both gravity-fed and pressurised. The reservoir holds a mix of water from the Leslie Harrison Dam and the Herring Lagoon bore field on North Stradbroke Island.
This is possible because the Alexandra Hills Reservoir connects to both the Leslie Harrison Dam and the Mount Cotton Reservoir at Tallow Wood Court. The Mount Cotton Reservoir is in turn connected to the Heinemann Road Reservoir at Mount Cotton which connects to both the SEQ Water Grid and North Stradbroke Island. Redland City is connected to the water grid via a pump station on Gramzow Road, Mount Cotton which allows water to be pumped to and from the city via the Heinemann Road Reservoir. This network of reservoirs, pump stations and pipelines ensures that water can be moved around the network and that multiple water supplies are available to residents living in all areas Redland City.
Wellington Point has even mix of both overhead and underground powerline networks servicing the suburb. This mix is due to the established farming and acreage areas of Wellington Point being sub-divided for urban development. The overhead powerlines are more susceptible to damage during severe weather which can result in power outages and fallen powerlines.
Fallen powerlines can cause significant dangers to the community, be aware that any object in contact with powerlines could be live. The area is more dangerous in wet conditions as water is an excellent conductor.
Remember: any metallic objects, including fences, will be electrified if they touch or are even close to a live fallen powerline. Even a tree branch can be a potential conductor of electricity if it is in contact with a live wire. Stay away from fallen powerlines and alert others of the danger – contact 000 or Energex on 13 19 62.
There is no domestic reticulated gas service within Redland City and no gas main that runs through the suburb of Wellington Point. There are however, homes within the area that use gas bottles to service hot water systems and cooking appliances. Residents are reminded to be diligent with the appropriate storage and maintenance of any gas bottles that they have located on their property.
Wellington Point is connected via landlines to the telecommunications and data networks. There is good mobile network coverage in Wellington Point with limited to no mobile reception black spots in the area. Telstra is the major supplier of telecommunications to the region; other suppliers include Optus and Vodafone.
The rail network enters Redland City via Thorneside, crossing the Tingalpa Creek to the north of the Thorneside Sewerage Treatment Plant and continues on to the Thorneside Station. From Thorneside Station the rail network continues east to Birkdale Station and Wellington Point Station where the line turns south-east to Ormiston Station and Cleveland Station where it terminates.
Current Flood Prone, Storm Tide mapping indicates the possibility of the rail network being cut by flood water on the Redland City side of Tingalpa Creek, north of the Tingalpa Station. If this were to occur, rail transport in and out of Redland City would be cut along with rail access to Brisbane City. This would prevent any evacuations via rail to the RNA Showgrounds which is the primary evacuation centre for Brisbane and an alternate evacuation centre for Redland City residents should the city’s infrastructure be significantly compromised by a disaster event.
