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.

The Tsunami Notification Zone classifications are used to differentiate the notification areas along the coast of BC. These Zones are used to add BC specific information to tsunami alerts issued from West Coast Alaska Tsunami Warning Center. BC tsunami alerts are disseminated via the Provincial Emergency Notification System (PENS) which encompasses automated phone calls to key stakeholders, faxes, email distribution and updates on the emergencyinfobc.gov.bc.ca website as well as Environment Canada's WeatherOffice, WeatherRadio and MediaWeb services. Each zone has a corresponding level of general risk associated with it, based on a suite of potential tsunami scenarios, which allows emergency managers to estimate the level of risk in each zone.
