The thing about Brisbane that people may not realise is that it is located on a flood plain. This means that there are some areas that are prone to flooding. The Brisbane City Council and State Government bodies work to ensure that they have the infrastructure in place to minimise the harm caused by flooding, but there are no guarantees. It is for this reason that the maps of flood zones can be really helpful for people who are looking to purchase in the area. However, for those who have already settled into a home and who are looking for ways of protecting their property from the possibility of flash flooding, the avenue of house-raising can provide peace of mind. But before we go any further into solutions, let’s take a look at two of the key factors that actually cause flooding in the Brisbane area.
Excessive Rainfall in the Eastern Areas of the Country
It doesn’t take a genius to realise that the more rain that is coming down in Brisbane and its surrounding areas, the more chance there will be of flooding. Depending which catchment areas are getting all the rain at any given time will determine the amount of flooding that will occur in the Brisbane area.
Water Releasing from Wivenhoe Dam
Water releases from the Wivenhoe Dam, are done for a variety of reasons and for a variety of different and sometimes opposing purposes. One is to release pressure on the dam to maintain its structural integrity, especially during times of increased rain and flooding where it may be full to capacity. Another is to lower the water content of the dam to allow for it to have space for capturing rainfall before a flooding event, so as to mitigate the possibility of flooding occurring. Unfortunately, there can sometimes be flooding downstream in the Brisbane flood prone areas, due to the functioning of the dam.
How to Keep Your Home High and Dry
Flood waters rising can be devastating for homes and their residents. It causes expensive damage to the infrastructure of the house, as well as possessions. For some residents, the choice to raise their house is a helpful solution that assists them in several different areas. One is that their property is lifted above the possibility of being damaged by flooding. Two, their insurance costs may decrease due to the increase in the safety of their house from flooding. Three, they gain peace of mind that they are protected from future weather events.
