Main Report

The District of Ucluelet is located on the Ucluth Peninsula between Barkley Sound and the Pacific Ocean. The coastal setting means that the area is exposed to coastal flood hazards from storms and tsunamis.  Climate change brings further hazards including sea level rise (SLR).  The District of Ucluelet recognises the importance of understanding coastal flood hazards and commissioned Ebbwater Consulting Inc. and its partner Cascadia Coast Research Ltd. to produce modern flood maps to better understand these hazards.

The final report will be used to identify ways to mitigate the risks associated with floods and tsunamis, and to help with emergency response planning and planning policy development.

The Technical Report, Appendices and Map Atlas Series are provided here.  Public Exhibit materials are currently in development and will be available on the website shortly.

Report Appendices

The main report is supported by the following appendices:

• Appendix A - Coastal Storm and Tsunami Hydrodynamic Modelling Analysis
• Appendix B - Coastal Erosion Preliminary Data Evaluation
• Appendix C - Coastal Flood Hazard Map Atlas (see below for map downloads)
• Appendix D - Coastal Storm Flood Depths and Flood Construction Level Differences

Appendix C - Map Atlas Series

Explanations of these maps and the scenarios illustrated can be found in the main project report.  For an explanation of the Flood Hazard Maps, please refer to page 47.  For an explanation of the Tsunami Flood Hazard Maps, please refer to page 56.

Series 1 - Coastal Storm Flood Hazard (Flood Depth and Extent)

This series of maps provide essential information on where water may go in a flood, and how deep that water might be.  The maps indicate where people, infrastructure, and cultural and environmental assets are most exposed to a flood hazard.

Series 2 - Coastal Storm Flood Planning Support (Sea Level Rise and Flood Construction Level)

This series of maps shows land that is not currently exposed to flooding from designated storms but will likely be in the future with sea level rises.  The Flood Construction Level (FCL) is used to establish the elevation of the underside of a wooden floor system or top of concrete slab for habitable buildings.

Series 3 - Tsunami Flood Hazard (Flood Depth and Extent)

This series of maps provide essential information on tsunami flood depths and extents as a result of a megathrust earthquake.

Series 4 - Tsunami Flood Planning Support (Tsunami Flood Planning Level and Vulnerability Zones)

The Tsunami Flood Planning level is the elevation below which areas are considered exposed to a tsunami hazard.  The Tsunami Flood Hazard Vulnerability Zones are related to the vulnerability of people as they walk or drive through flood waters, or as they remain inside a structure during a tsunami flood event.
