Jacksonville launches climate-change resiliency plan with 45 actions over 50 years to mitigate flooding risks.

Jacksonville has launched its first resiliency strategy to combat intensified flooding linked to climate change. The plan, developed by the city's resiliency office, outlines 45 actions over 50 years to mitigate risks, including prioritizing low-risk development areas, improving drainage, and preserving green spaces. Without changes, up to 430,000 residents could face flooding risks, up from nearly 140,000. The strategy also addresses extreme heat through increased tree coverage and splash pads.
