A global network helping cities build resilience to urban flooding

The Urban Flooding Network supports cities to identify, plan and implement projects that increase resilience to flooding.

As part of C40’s wider work on climate adaptation, the network enables cities to share practical solutions and remove the technical, financial and political barriers to flood resilience. It works closely with the Water Security Network and Cool Cities Network to address interconnected climate risks.


How the Urban Flooding Network supports collaboration between cities

The network enables cities to:

  • share knowledge through peer-to-peer exchange, webinars and city-to-city calls
  • collaborate and problem-solve on removing technical, financial and political barriers to flood resilience
  • build capacity through workshops and study tours
  • work with the Water Security Network on sustainable water management and the Cool Cities Network on urban heat adaptation
  • coordinate with other C40 networks on energy, buildings, transportation, land use and waste to ensure flood resilience is integrated across city systems

Core areas of action of the Urban Flooding Network

Governance and holistic water management

Promoting integrated water management by engaging stakeholders and communities in flood planning and response.

Measuring and monitoring

Sharing tools and technologies to map flood-prone areas and model impacts on residents, workers and critical infrastructure.

Flood response

Sharing best practices in emergency preparedness and response strategies for significant flood events.

Flood reduction

Supporting cities to adapt through sustainable drainage, retention, storage, infiltration and blue-green infrastructure.
