Victoria Point – Natural Hazards and Critical Infrastructure

Natural Hazards

Bushfire

Victoria Point bushfire hazard areas spread throughout the suburb with a large section of land identified as ranging from moderate to very high bushfire hazard running the length of Eprapah Creek, virtually from its mouth at Point O’Halloran to Kingfisher Road at the western boundary of the suburb. These bushfire hazard areas border both rural and residential developments along with shopping centres and the Victoria Point High School

Properties adjacent bushland areas may be risk of ember attack should there be a bushfire in the vicinity. During a wild fire, embers can travel up to 3 kilometres 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 Queensland Rural Fire Service website and download the 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 is also investigating arrangements with Queensland Fire and Emergency Services to support fire mitigation activities around the city.

Flood Prone, Storm Tide

The Victoria Point area has potential to experience flooding as a consequence of either tidal inundation or flash flooding resulting from heavy rainfall events. Victoria Point has a number of waterways running through it, the largest of these being the Eprapah Creek system which flows into Moreton Bay at the north-eastern coastline of Victoria Point. Eprapah Creek is impacted by both tidal inundation and flash flooding resulting from heavy rainfall events.

The Eprapah Creek system primarily runs through bushland reserve areas, however if the creek floods, current mapping indicates that it will impact the Lakeside Shopping Centre at Victoria Point, the Victoria Point Sewerage Treatment Plant, Faith Lutheran College and other large properties along Beveridge Road and could quite possibly cross Redland Bay Road near the Boundary Road intersection cutting access to Victoria Point.

Current mapping also indicates that low lying areas of Thornlands may experience tidal inundation as a result of a storm tide event. Areas of greatest impact appear to be the Point O’Halloran Conservation Area, Wilson Esplanade, White Street, Base Street, and the Thompson’s Beach area which includes Eagle Street, Thompson Esplanade, Beach Court and Simon Street. Also in the vicinity of Thompson’s Beach are two large retirement villages, current mapping indicates that both would experience some impact from tidal inundation during a storm tide event.

Landslide

Landslide Hazard mapping indicates that Victoria Point has a very limited landslide risk, with a few small pockets generally confirmed to parkland or bushland areas. There are a few residential properties to the north of the Redland bay Golf Course which are identified as having a low landslide hazard risk.

Residential development in these areas needs 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

Critical infrastructure at the time of a disaster event includes utilities such as power, water, sewerage, telecommunications, gas and road and rail networks. Impacts of a disaster on these services may have far reaching long term affects for mainland communities.

Sewage

Victoria Point has a mix of sewered and non-sewered areas. The residential areas, which cover the majority of the suburb, are connected to the city’s sewer network. Effluent from these areas is directed to the Victoria Point Sewerage Treatment Plant located off Link Road. Hazard mapping indicates that the Victoria Point Sewerage Treatment Plant is adjacent bushland identified as being moderate bushfire hazard and may be impacted by tidal inundation during a severe storm tide event.

The rural acreage areas, located in the south and west of the suburb are not connected to the city’s sewer network and 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.

Water

Victoria Point receives its water supply from the Heinemann Road Reservoir, located at Mt Cotton. The Heinemann Road Reservoir services the Southern Moreton Bay Islands, Redland Bay, Victoria Point and Thornlands and is connected to the Mt Cotton Reservoir at Tallow Wood Court, Mt Cotton which services Mt Cotton and Sheldon. The Mt Cotton Reservoir in turn is connected to the Alexandra Hills Reservoir located at Hilltop Circuit, Alexandra Hills making possible the supply of water to Redland City’s northern suburbs should there be issues with Leslie Harrison Dam which traditionally services the north of the city.

The Heinemann Road Reservoir is also connected to the Herring Lagoon bore field on North Stradbroke Island and the South East Queensland Water Grid via a pump station on Gramzow Road, Mt Cotton. The connection to the South East Queensland Water Grid 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.

Electricity

Victoria Point is serviced by a mix of both overhead and underground powerline networks, with the primary 33kV overhead powerline running through the suburb along Cleveland-Redland Bay Road to Redland Bay. An underwater 11kV powerline connects to Coochiemudlo Island from Victoria Point Reserve at the end of Colburn Avenue.

The more recently developed estates along Bunker Road behind the Victoria Point Shopping Centre, is primarily where the underground powerline network is located. The longer established areas near the waterfront are supplied by the overhead powerline network.
The overhead powerlines are more susceptible to damage during severe weather which can result in power outages and fallen powerlines. Fallen powerlines oppose 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 Energex on 13 19 62.

Gas

There is no domestic reticulated gas service within Redland City. Nor is there a gas main that runs through the suburb of Victoria Point. There are however homes within the area that use gas bottles the 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.

Telecommunications

Victoria Point is connected via landlines to the telecommunications and data networks. There is good mobile network coverage in Victoria 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.

Harbours and Marinas

The Victoria Point Reserve, located at the end of Colburn Avenue is the primary access point to Coochiemudlo Island. Passenger ferry services to the island launch from the deep water jetty whilst the barge service utilise the ramp facility. There is a boat ramp within the precinct to launch small vessels and Volunteer Marine Rescue Victoria Point also has their base and boat launching facilities within the Victoria Point Reserve area.

Current flood prone, storm tide mapping indicates that the area of Victoria Point Reserve that contains the marine infrastructure may be impacted by tidal inundation during an extreme storm tide event that could result in damage to essential infrastructure.
There are also a number of small boat moorings dotted along the Victoria Point coast line. These moorings and vessels are at risk of structural damage should a storm tide event impact the area.

Road Network

REMEMBER: If it’s flooded, forget it!

On 20 November 2012, Iain MacKenzie – Inspector General Emergency Management said “There is absolutely no excuse for motorists who deliberately drive or walk past a road closed sign and into floodwaters. Even if you are in familiar territory and believe local knowledge will get you through, think again. Floodwaters are treacherous and the dangers are hidden beneath the surface.”

Every year people are hurt, or die, trying to cross or play in flooded waterways. It can happen anywhere – roads, creeks, dams, parks or backyards. Residents should be aware of the dangers connected to floodwater or swift flowing water such as: slippery surfaces; uneven ground; strong currents; sharp objects; electrical current; fences; vehicles; rocks; long grass; tree branches; sewerage; and chemicals.

If you get trapped in floodwater, you not only put your life and the lives of the people with you at risk, but you also put the lives of the rescuers at risk too.

Localised flooding may temporarily restrict access and cut roads in some areas of Redland City. Please consider this when planning to drive during periods of heavy rain. A list of the areas impacted by localised flooding can be found here.

Rail Network

Currently there is no rail infrastructure in Victoria Point and there are no plans to extend to rail network to Victoria Point in the near future.
