CityFloodMap.Com

In-depth data and analysis on extreme weather and flood risks on www.cityfloodmap.com share engineering insight on complex topics of infrastructure design and performance, urban hydrology, flood risk assessment, and cost-effective risk management. Our goal is to promote critical, evidence-based "Thinking Slow on Floods and Flow" to improve flood and stormwater management policies and achieve effective environmental outcomes. R.J. Muir, Toronto, ON.
