A U.S. Army Corps of Engineers plan to protect Miami-Dade County from hurricane storm surges over the next 50 years with flood gates across rivers, and a mile-long flood wall along its upscale waterfront, could cost nearly $4.6 billion.

The tentative plan, which is now open for public comment, is the latest and most fully detailed. The plan also calls for elevating about 2,300 flood-prone structures.

The rain that pounded South Florida last week, and dumped a half foot on Miami International Airport in just two hours, also tested the limits of the old Tamiami Canal.

South Florida came under another flood watch Wednesday evening as more rain threatened to drench already saturated ground.

The National Weather Service’s Miami office warned that the rain could prompt more flooding in Miami-Dade, Broward and Palm Beach counties as parts of Miami-Dade dug out from a Tuesday deluge.

Coping with storm surge fueled by rising seas in the Keys means elevating homes, buyouts in vulnerable areas, protecting important places like hospitals and wastewater plants and stabilizing parts of the Overseas Highway that could get washed out in storms.

The city of Miami officially rolled out its plan to fight sea rise and tackle threats from climate change at a rooftop ceremony overlooking Biscayne Bay Thursday.

The plan follows a yearlong effort focused on five critical areas that included flooding, increasing heat and the goal of cutting carbon emissions. That effort led to 86 specific actions, said Resiliency Chief Jane Gilbert — from increasing insurance discounts for flood-weary residents to overhauling the city’s aging stormwater system.

Engineers are designing for an increasingly soggy future in a rough industrial bay west of Riviera Beach, building Erector set-style defenses to keep out a wily intruder — water.

On a satellite map, the Lake Wales Ridge stands out as a sandy spine running through the middle of Florida. From Clermont in the north, south almost to Lake Okeechobee, rolling hills give the area a very un-Florida-like feel.

Florida is sending $25 million to South Florida to buy out homeowners ready to surrender to hurricanes and rising seas.

On Tuesday, the Florida Department of Economic Opportunity awarded $44 million in Hurricane Irma relief money to cities and counties around the state to purchase vulnerable property in an attempt to cut the cost of future damage. In South Florida, Monroe County will receive the lion’s share - $15 million - with another $5 million going to Marathon, about $4.5 million to Miami-Dade County and just over $200,000 to the Village of Islamorada.

In his new book, "The Geography of Risk: Epic Storms, Rising Seas, and the Cost of America's Coast," Pulitzer-prize winning author Gilbert Gaul takes a look at the U.S. history of coastal development since World War II - and finds a recipe for disaster.

Floridians have another year of reprieve before they face a likely hike in their flood insurance premiums, thanks to political pressure from Congress over a potentially drastic revamp to the National Flood Insurance Program.

The planned change to the way the NFIP charges policyholders is meant to claw the program out of its multibillion-dollar debts and help the nation adapt to the growing risk of climate change — in exchange for an end to the subsidies coastal residents have relied on for decades.

Ask any consumer — good credit goes a long way.

It works the same for local governments. Increasingly investors in the bonds of local governments want to know more about the risks those cities and counties face from climate change, and how those risks could affect the governments’ ability to repay their debts.

A new United Nations climate report released in Monaco this week paints another grim picture for the planet and Florida.

Seas are not only rising, but accelerating and worsening flood threats.

A King Tide forecast for the weekend could bring flooding to parts of South Florida.

The tide is expected to peak Sunday and Monday mornings between about 9 and 10 a.m. and may approach record highs as the moon sweeps closer to the earth.

"They do look like they'll be roughly comparable to the highest tide we saw in 2015 and 2016, which were pretty noteworthy," said Brian McNoldy, a hurricane researcher who tracks the tides at the University of Miami's Rosenstiel School of Marine and Atmospheric Science.
