The US city of Miami is to invest billions of dollars to tackle its vulnerability to rising sea levels, a reality that already affects the daily lives of residents used to constant flooding.

Miami-Dade County Mayor Daniella Levine-Cava said Friday she will protect communities hardest hit by rising sea levels, which eat away at beaches and leave residents particularly vulnerable to flooding during hurricane season. 

"We must continue to focus on restoration, preservation and protection of this sacred space," she told a news conference. 

"And so we will be together investing billions of dollars... in our infrastructure so that we can lift this community and others that are so affected by sea level rise," she added.

She cited "adaptation action areas" as a first priority to be studied, which would include raising low-lying roads, and waterproofing and converting southern Florida's widely used septic tanks into sewage systems. 

The area, with extensive wetlands and sitting on porous stone that acts like a sponge, makes the state one of the most at risk from rising sea levels. 

The problem is so visible that, during the summer rainy season, it is common to see Miamians kayaking along flooded avenues and cars sunk up to their windows. The city of Miami Beach, which is part of Miami-Dade County, invested millions of dollars in raising the level of many of its streets in 2016. And some private entrepreneurs have proposed creative, if expensive, ways to adapt to the challenge. 

It is valued at $5.5 million and adjusts to rising sea levels.
