Flooding poses increasing risks to cities, transportation networks and critical infrastructure. CDM Smith partners with clients to plan, design and deliver flood protection solutions that reduce risk, enhance resilience and support sustainable growth—today and into the future.
Flood risk is increasing as climate change, urbanization and aging infrastructure place greater pressure on communities and critical assets. CDM Smith helps clients understand, manage and reduce flood risk through integrated planning, advanced modeling and resilient engineering solutions. Our teams address all sources of flooding—riverine, pluvial, coastal and groundwater—combining technical rigor with practical delivery. From early risk assessment to detailed design and construction support, we partner with clients to deliver solutions that are effective, sustainable, and adaptable to future conditions.
We take a holistic approach to flood protection—addressing riverine, pluvial, coastal and groundwater flooding through integrated planning, engineering design and infrastructure delivery. Our solutions balance technical performance, environmental considerations and long-term resilience.
Our teams use advanced hydraulic and hydrologic modeling to understand flood behavior, assess risk and test mitigation options. These insights inform right-sized designs for flood defenses, drainage systems and floodplain management strategies.
Where appropriate, CDM Smith integrates nature-based and green infrastructure solutions with traditional engineering to reduce flood risk, improve water quality and enhance public spaces—supporting both resilience and livability.
We support clients across the full project lifecycle—from flood risk assessments and master planning to detailed design, tender support and construction services—ensuring solutions are implementable, compliant and durable.
