Cleveland has pockets of high to very high bushfire hazard areas scattered throughout the suburb. All of these areas are bordered by heavily populated residential developments and some back onto key infrastructure such as the Redlands Hospital, the commercial precinct of Enterprise Street and the Alexandra Hills Sewerage Treatment Plant (which is accessed from Weippin Street, Cleveland through the high bush fire hazard area).
Properties adjacent bushland areas may be at 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 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 Cleveland area has potential to experience flooding as a consequence of either tidal inundation or flash flooding resulting from heavy rainfall events. Cleveland has two main waterways running through it, those being Hilliard’s Creek and Ross Creek, both of which empty into Moreton Bay. Potential impacts for Cleveland of Hilliard’s Creek experiencing flash flooding are limited to the bushland areas that surround the creek. Ross Creek however cuts a path through central Cleveland via a combination of reserve land and culverts which skirt heavily developed residential areas until it runs under Shore Street West and into the Ross Canal which is part of the Raby Bay canal estate.
Current mapping also indicates that low lying areas of Cleveland may experience tidal inundation as a result of a storm tide event. Areas of greatest impact appear to be along the Cleveland peninsula to Cleveland Point, around the vicinity of Little Shore Street at Raby Bay, Toondah Harbour and the Priority Development Area precinct at the end of Middle Street, and the sports fields at the end of Bay Street. If tidal inundation were to impact the sports fields at the end of Bay Street, it is likely that the southern end of both Beach Street and South Street would be cut also. This would effectively isolate the residential community in this area which straddles the boundary of Cleveland and Thornlands.
Landslide Hazard mapping indicates that Cleveland has either no or low landslide risk. The areas of low landslide hazard are generally confined to parks and reserves along the shoreline areas and to west of the suburb near Wellington Street.
There is some residential development in these areas that 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 and road and rail networks. Impacts of a disaster on these services may have far reaching long term affects for mainland communities.
The sewer network services the entire suburb of Cleveland and connects into the Alexandra Hills Sewerage Treatment Plant located to the east of Hanover Drive. Current hazard mapping indicates that the Alexandra Hills Sewerage Treatment Plant is surrounded by bushland identified as being a high to very high bushfire hazard.
Cleveland 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 Mt Cotton Reservoir at Tallow Wood Court, Mt Cotton. The Mt Cotton Reservoir is in turn connected to the Heinemann Road Reservoir, Mt Cotton which connects to both the South East Queensland Grid and North Stradbroke Island. Redland City is connected to the South East Queensland Water Grid via a pump station on Gramzow Road, Mt Cotton which allows water to be pumped to and from the city via the Heinemann Road Reservoir, Mt Cotton. 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.
The Redland City’s primary power infrastructure, an 110kV overhead powerline that has passed from Brisbane, through Capalaba and Alexandra Hills, terminates in Cleveland at the top of the Enterprise Street industrial estate. From this point power is fed both north to Cleveland and south to Thornlands, Victoria Point and Redland Bay via a 33kV overhead pipeline network.
Cleveland has a mix of both overhead and underground powerline networks servicing the suburb. The more recently developed Raby Bay estate is primarily where the underground powerline network is located, whilst the remainder of Cleveland which has been the long established is 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.
Cleveland has a pressurised gas main that enters the suburb through bushland east of the Cleveland Cemetery. From the cemetery, the gas main runs both north and south along Wellington Street.
Heading south from the cemetery, the gas main continues along Wellington Street to Weippin Street where it services a number of industrial estates and the Redlands Hospital. The gas main continues along Wellington Street, past Weippin Street to Enterprise Street where it services yet another industrial area. This is where the gas main terminates its southern arm.
Heading north from the cemetery, the gas main continues along Wellington Street to Shore Street West, servicing the Cleveland Aquatic Centre along the way. At Shore Street West, the gas main travels west servicing the industrial area as well as travelling east into Cleveland town centre along Middle Street.
An arm of the gas main extends south from Middle Street, along Doig and Waterloo streets to service an industrial estate behind Ross Court. The trunk of the gas main continues along Middle Street servicing a number of commercial centres before terminating at Toondah Harbour. A second arm of the gas main extends from Toondah Harbour along Shore Street East to service the Grand View Hotel where it terminates.
There is no domestic reticulated gas service within Redland City; however there are homes within the area that use gas bottles to service hot water systems and cooking appliances. Residents are reminded to diligent with the appropriate storage and maintenance of any gas bottles that they have located on their property.
Cleveland is connected via landlines to the telecommunications and data networks. There is good mobile network coverage in Cleveland 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
Cleveland contains some of the city’s more critical marine infrastructure, namely Toondah Harbour and the Raby Bay marina and canal estate. Toondah Harbour is viewed by many as the gateway to North Stradbroke Island being the primary launch site for barge and ferry services to the island. Currently operating out of Toondah Harbour are two passenger only ferry services and two vehicular barge services. Toondah Harbour has been identified as a Priority Development Area with the view to developing a contemporary multi-use precinct in the current harbour location. For further details please visit the Council’s website.
The Raby Bay is a relatively large canal estate with two deep water access points and a marina development. The marina development is a multi-use precinct which includes a mix of businesses, cafes and restaurants, day spa and medium density unit complexes. The marina has refuelling capabilities and docking facilities for visiting vessels therefore increasing vessel traffic beyond that of the residential vessels only. Charter accompanies also operate out of the marina. Whilst current mapping indicates limited impacts from storm surge to the marina and canal estate areas, residents and business owners should be prepared for the possibility of their homes and businesses experiencing tidal inundation during an extreme storm tide event.
There are also a number of small boat moorings dotted along the Cleveland coast line. These moorings and vessels are at risk of structural damage should a storm tide event impact the area.
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.
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.
Priority Development Areas
The Queensland State Government has granted Priority Development Area (PDA) status to two sites within Redland City, those being Toondah Harbour in Cleveland and the Weinam Creek Transport Hub in Redland Bay. Both of these precincts will incorporate residential, retail and tourist facilities and will be the gateway to North Stradbroke Island and the Southern Moreton Bay Islands.
The Toondah Harbour and Weinam Creek redevelopment is one step closer after Council on Wednesday 19 March 2014 voted to make some recommendations on what these key areas could look like. The recommendations to the State Government are part of the planning process and reflect a range of community and commercial views.
Council is committed to getting the balance right to attract investors who will fund better access to the foreshores and improvements in these critical areas. This includes improved ferry ramps and passenger facilities, better transport interchange and parking, enhancements to parkland and improved pedestrian and cycle links to the bay.
To achieve this balance at Toondah Harbour, Council has recommended:
- Building height reduced by one third, now capped to 10 storeys (down from up to 15 storeys in the original draft scheme and an increase of three storeys to the seven storeys currently allowed at the site.
- No net loss of public open space (including GJ Water Park which remains as public open space).
- Marina berths halved to 400 (down from possible 800 berth in the original draft scheme).
