Coastal Design Sea Levels- Coastal Flood Boundary Confidence Intervals
PLEASE NOTE: The Coastal Design Sea Levels – Coastal Flood Boundary datasets currently show data published in February 2011. An update to the data is currently planned for August 2019. This statement will be updated when the data update is complete. This metadata record is for AfA product AfA188-2. Extreme Sea Level Confidence information is part of Coastal Design/Extreme Sea Levels, a GIS dataset and supporting information providing design / extreme sea level and typical surge information aroun
