Existing Vulnerabilities
- Halifax is highly vulnerable to coastal flooding, storm surges, and erosion due to its extensive 2,400 km coastline, which is subject to high wave energy and rising sea levels.
- The region has a history of significant flooding events, such as the July 2023 floods, which caused extensive damage to infrastructure and highlighted the vulnerability of certain river systems and urban drainage areas.
- Certain populations, including seniors, low-income residents, and those with disabilities, are disproportionately affected by extreme weather events due to limited adaptive capacity and housing challenges.
- The municipality maintains a vulnerable persons registry to assist in emergency response, reflecting the recognized need for targeted support during severe weather.
Weather Impact Thresholds
- Coastal flooding: High hazard level; potentially damaging waves are expected to flood the coast at least once in the next 10 years, with storm surges significantly increasing the risk during high tides.
- Rainfall: While specific municipal thresholds vary by catchment, historical data indicates that extreme rainfall events (e.g., 250 mm in less than 24 hours) cause catastrophic flooding, infrastructure damage, and service disruptions.
- Wind: Coastal areas are particularly susceptible to high winds, with slopes facing the coast receiving the most impact; wind-borne debris can cause structural damage and exacerbate the impact of other weather hazards.
Exposed Populations and Assets
- Coastal communities and infrastructure are at high risk from storm surges, erosion, and inundation, particularly in low-lying areas.
- Critical infrastructure, including transportation networks and power systems, is vulnerable to damage from heavy precipitation, flooding, and high winds.
- Equity-deserving groups and historically marginalized communities may be disproportionately exposed to flood risks due to systemic factors affecting land use and infrastructure quality.
