Level 1 strategic flood risk assessment - October 2020
The purpose of this strategic flood risk assessment is to collate and present the most up-to-date flood risk information from all sources for use by ourselves to inform the preparation of local plans and prudent decision-making by development management officers on a day-to-day basis.

Level 2 strategic flood risk assessment - January 2021
Where land outside flood zone 2 and 3 cannot appropriately accommodate all development, the NPPF's exception test must be applied. The scope of the level 2 strategic flood risk assessment is to inform the exceptions test by considering the flood risk from all sources, as well as the detailed nature of the flood characteristics and mechanisms within a flood zone including:
- flood probability
- flood depth
- flood velocity
- rate of onset of flooding and
- duration of flood

Level 1 strategic flood risk assessment - December 2015
We have completed the level 1 strategic flood risk assessment which will be followed shortly by a level 2 assessment.
The Environment Agency is continuously monitoring and updating flood risk data, so reference should always be made to the latest published flood maps. Please always visit the Environment Agency website for more information.
When reading the strategic flood risk assessment and guide to sequential testing for planning applications, the flood risk SPD draft is currently not adopted and cannot be given any weighting. Please discuss the current flood risk sequential test with development management.

Level 1 strategic flood risk assessment - November 2008
The level 1 strategic flood risk assessment which was first published in November 2007 has been updated to take account of more recent data released by the Environment Agency regarding Selby Dam and its tributaries and to reflect our emerging core strategy.
Since the publication of the level 1 report, the Environment Agency has issued a revised flood map for the River Ouse and the River Wharfe. The Environment Agency is continuously monitoring and updating flood risk data, so reference should always be made to the latest published Flood Map. Please visit the environment agency website for more information.

Level 2 strategic flood risk assessment - February 2010
The flood risk information in the level 1 strategic flood risk assessment has been used to undertake a PPS25 sequential test and a level 2 strategic flood risk assessment.
The purpose of the sequential test (pdf / 702 KB) is to steer development to areas with the lowest probability of flooding. Since the scale of growth required exceeds the amount of low flood-risk land available, particularly in Selby, this means accommodating some development in higher flood-risk areas, including a number of strategic development sites.
The level 2 strategic flood risk assessment (pdf / 7 MB) provides detailed information on specific flood risks for each of the strategic development sites, including recommendations for managing and mitigating the risk.
Addendum to level 2 strategic flood risk assessment and PPS25 sequential test
Following the publication of the revised flood maps we have reviewed the PPS25 sequential test previously undertaken as part of the level 2 strategic flood risk assessment in order to test the findings in light of the new data. The results are published as a separate addendum to the PPS25 sequential test (pdf / 315 KB).
In view of the fact that a much larger area of land at the proposed Cross Hills Lane strategic development site is now within flood zone 3 (high flood risk) the level 2 strategic flood risk assessment for this site has also been reviewed. This is published as a separate addendum to the level 2 strategic flood risk assessment (pdf / 14 MB).
