Policy Solution

Cool corridors

Commitment

Overview:

Summary: Green and blue infrastructure immediately adjacent and parallel to prevailing winds cools corridors. Incorporating addtional urban design principles in zoning can be used to optimize natural wind flow for cooling and prevent heat from radiating off of other buildings.

Implementation: Update design guidelines to encourage creation of cool corridors.

Considerations for Use: This is most applicable to new developments and is harder to implement in existing, highly dense areas. Natural landscape features like hills, valleys, or bodies of water can also function as ventilation corridors.

  • Policy Levers: The mechanism municipalities can use to actualize the intervention. These policy levers will likely be used in combination with each other.

    CommitmentGovernments set ambitious goals or targets to guide prioritization and investment.
  • Trigger Points: Opportunities for municipalities to implement risk reduction and preparedness interventions based on the policy lever, building on the United Nations Environment Programme triggers used in the Beating the Heat handbook (2021).
