A general purpose map viewer for New Brunswick / Visualiseur de cartes du Nouveau-Brunswick.

Approximate boundaries for all land parcels in New Brunswick. The boundaries are structured as Polygons. The Property Identifier number or PID is included for each parcel.

The New Brunswick Flood Hazard Maps present a series of flood hazard maps for the province of New Brunswick. The maps outline the predicted location, frequency and depth of coastal and inland flooding in New Brunswick and incorporate the future impacts of climate change.Flood events are usually expressed in terms of a return period or an Annual Exceedance Probability (AEP). The return period or the AEP gives the likelihood that a flood event could occur in any given year, and so helps estimate how often an area will be impacted by flooding. Flood extent mapping in New Brunswick delineates a zone where floods have a 5% chance of occurring in any year (5% AEP or 20-year return period) and a zone where floods have a 1% chance of occurring in any year (1% AEP or 100-year return period).In a coastal environment, these flooding events could be caused by a storm surge coinciding with a high tide. For more information on coastal flooding, click here. The upper end of the range of uncertainty was used in mapping flood hazards on the coast. This report also contains water levels for other return periods (AEPs) and time horizons that were not mapped in this viewer. These additional water levels are presented in the Tables of Appendix A and Appendix B. As explained in the report, the risk remains for the potential collapse of portions of the West Antarctic ice sheet which could cause global mean sea level to rise further. This report has addressed this uncertainty by projecting a further 0.65 metres of sea-level rise be added to the 2100 water level estimates. These projections are available in Appendix A and Appendix B of the report.In an inland environment, these flooding events could be caused by heavy rainfall or combination of rainfall and snowmelt.

(In development)Present Day Flood, 1 in 20 year (5% Annual Exceedance Probability) – This is a present-day flooding event that has a 5% chance of being reached in any given year. This is also known as a 1 in 20-year return period flood event.Present Day Flood, 1 in 100 year (1% Annual Exceedance Probability) - This is a present-day flooding event that has a 1% chance of being reached in any given year. This is also known as a 1 in 100-year return period flood event.2100 Flood with Climate Change, 1 in 20 year (5% Annual Exceedance Probability) - This is a flooding event that will have a 5% chance of being reached in any given year, when adjusting for climate change impacts to the year 2100. This is also known as a 1 in 20-year return period flood event, adjusted for climate change.2100 Flood with Climate Change, 1 in 100 year (1% Annual Exceedance Probability) - This is a flooding event that will have a 1% chance of being reached in any given year, when adjusting for climate change impacts to the year 2100. This is also known as a 1 in 100-year return period flood event, adjusted for climate change.2100 Higher High Water Large Tide (HHWLT) - This is the projected extent of the high tide in the year 2100. With sea levels continuing to rise due to climate change, this serves as a good reference to understand what sea levels will look like in the future.
