First published in December 2011, the National Flood Risk Assessment (NFRA) has provided Scotland with the knowledge and tools to assess the causes and consequences of flooding. The assessment has considered the likelihood of flooding from rivers, groundwater and the sea, as well as flooding caused when heavy rainfall is unable to enter drainage systems or the river network.
Now that we have reached the end of the of the first Flood Risk Management planning cycle, SEPA is working with key stakeholders to review and update the NFRA as part of preparations for the second planning cycle. This is a key requirement of the FRM (Scotland) Act 2009 which states that SEPA must carry out a NFRA every 6 years.
Reviewing the NFRA every 6 years is essential because SEPA and its stakeholder's understanding of flood risk is constantly developing and it is important that this knowledge is captured. This will ensure SEPA is working with the most up to date information to effectively support sustainable Flood Risk Management.
Since the publication of NFRA in December 2011 a number of changes will influence its re-release in 2018 including:
The NFRA is the product used to guide the identification of Potentially Vulnerable Areas (PVAs) - the primary unit for managing strategic flood risk management activities. PVAs are being reviewed and updated within cycle 2 in line with the NFRA update. As there have been significant changes to the NFRA between cycle 1 and cycle 2 including advances in our modelling and mapping data and the methodology behind the assessment, a full re-designation of PVAs is being undertaken.
A national public consultation of the outputs will take place during late spring 2018, and the second NFRA and PVAs will be formally published on 22 December 2018.
