As part of our surveys, we look to ascertain what types of flooding may affect the property, and why this may occur. Once the root cause is understood, we then look towards working together to manage and minimise the risk to the property. We often explain a true flood survey should be like forensics, assessing every aspect in close detail to establish why the flood occurred.
Our flood risk management approach is hierarchal, with various aspects considered prior to making any recommendations.
Whilst flood mapping provides a useful overview on risk, it should be noted that flood maps are undertaken on a national scale and may not represent the true risk. Surface water flood maps are also unlikely to account for localised drainage connections.
As part of the survey, we also conduct a consultation to understand any historic flood occurrences and client concerns. Data on historical floods is highly useful to establish a picture of what contributes to flooding in a catchment or on the coast. Additional information can be used to build a good understanding of the links between the sources and impacts of flooding.
Where a more detailed risk assessment is required, we can obtain Environment Agency, SEPA, or Natural Resources Wales model data to compare with land levels, providing depth indications for different return periods.
