| Flood Risk Areas and Historical Floods |
Data purpose:
- To show the locations of potential and historical flood areas so that informed decisions can be made with respect to future planning and development.
- To help New Brunswick property owners and decision makers understand the spatial extent of flooding for the 2008 and 2018 lower Saint John River spring floods.
- Flood risk areas display the extent of known historical flood events as well as areas that have a probability of flooding as determined from historical records.
- The polygon data includes the description of the flood event, the typical causes of the flood and any associated place name keys.
- The line data indicates the limits of the flood risk mapping information and the 2008 and 2018 flood data.
- Flood extents for the 2008 and 2018 Lower Saint John River floods are included.

Data issues:
- Accuracy – Flood extents should only be used as a rough guide as the accuracy of the modeling and digitizing of flood information is unknown.
- Completeness – there are areas where the flood extents are not completely represented. Adjacent areas beyond the flood limit lines may also be at risk of flooding.
- Some properties that experienced flooding in 2008 may not be shown as flooded in this application if the landscape was altered between 2008 and when the elevation data was collected in 2018.
