If your development falls under one of the flood zones, a principal designer assesses the risks before a project is started. One vital task is to get a flood risk assessment report. An FRA details the main flood risk to a development site and also provides recommendations on how to mitigate the impact of flooding at the development site and its surrounding areas. It will help you determine if your new development is sustainable and how it could impact the environment and increase the risk of a flood. So, what exactly does this report focus on?
Assessing Flood Hazard
This includes assessing the magnitude of a flood such as the velocity of moving water, quality of water, duration of inundation, and more. It also considers the maximum level the water reaches annually, at a given location and if it could exceed that level at any given time.
Assessing The Performance Of Flood Protection
A flood risk assessment helps determine how the flood risk can be reduced through structural measures such as floodwalls or building reservoirs. The performance of these reservoirs during floods is analysed to prevent any impending dangers.
Assessing Vulnerability And Exposure
Assessing the vulnerability and exposure of your structure would help determine the damage that could be caused during a flood. The structure is often categorised according to its construction type or other characteristics that will help predict the damage, corresponding to specific water depths.
Assessing The Risks Involved
A flood risk assessment will help you find out if your proposed development may be affected by current or future flooding or if it would increase the risk of a flood elsewhere. It would also help you take appropriate measures to mitigate any risks in the future.
Knowing the components of a flood risk assessment would help you make an informed decision on risk management. Contact our principal designers for more information on flood risk assessment.
