What is a Flood Survey?
A Flood Survey assesses the level of risk that your property may be exposed to in the event of potential flooding. Skilled Surveyors from Geosurv analyse the topography of the land and take into consideration various other factors to determine the level of flooding risk on your residential property. They also determine which potential flooding or drainage problems your land or proposed development may face, and prepare detailed reports and certifications to satisfy the requirements of local councils.
In higher risk, flood-prone areas, a licensed flood survey may be necessary to permit approval for residential developments to take place.
Do I need a Flood Survey?
Unless it is very obvious that your property is not at any risk of flooding, only a skilled Surveyor can determine if a Flood Survey is necessary or if the risk of flooding is significant. At Georsurv, our experienced Surveyors can look into records and seek information from authorities, but a site inspection may be necessary to determine the specific level of risk relating to your property.
Is a Flood Survey mandatory?
If you propose to build in a flood-prone area, a Flood Survey will be necessary. Local councils may only issue building approvals if the proposed floor level meets certain criteria based on flood level risks.
But whenever you are buying residential property or redeveloping, checking for flood risk is wise and therefore recommended so you can ensure your investment and your family are safe. The survey will tell you if your property may flood as a result of what is called the ‘Australian Height Datum’, or because of insufficient drainage.
What does a Surveyor do?
Experienced Surveyors in Australia determine land levels based on sea level together with the average of meticulously recorded tide gauges, known as the ‘Australian Height Datum’. Factors of flood expectancy are also taken into consideration, expressed in 1:5 (a once in five years flood), 1:20 and up to 1:100.
A Topographic Survey will determine the precise elevation of your land relative to sea level, compare it to the data and assess its relevance to the details of your land, the buildings and other features located or proposed to be built on it.
