A new Miami law would allow developers to build up to double the allowable density in certain neighborhoods if they agree to pay into the city’s Resilience Trust Fund, according to an article in The Real Deal.

The trust fund is designed to pay for flood control and climate resilience projects including raising streets, replacing seawalls, and pump stations. Critics of the policy say it would give developers an open door to building oversized projects in flood zones rather than planning for more sustainable development. 

The city commission approved the proposal, but it requires a second vote to go into effect. “Aaron DeMayo, who chairs the city’s Climate Resilience Committee, supports the proposal, but said he found it ‘somewhat ironic that we’re incentivizing additional development capacity in an area that obviously is already flooding significantly.’”
