Oops. Florida Communities Up To 20 Miles Inland Flooded During Eta In 2020 - Canals Couldn't Drain

Sea-level rise may appear to be a problem only for coastal residents, a hazard that comes with the awesome views and easy access to the beach. But neighborhoods 20 miles inland are starting to feel the impact, as the Atlantic Ocean’s higher elevation makes it harder for drainage canals to keep them dry. The problem showed up last year in Tropical Storm Eta, when floodwater remained in southwest Broward neighborhoods for days, partly because the elevated ocean blocked canals from draining the region.

“It was pretty scary,” said Barb Besteni, who lives in far west Miramar. “I stepped out of house into ankle-deep water. It came three-fourths up the driveway. I’d never seen the water that high. It was scary because I didn’t know if it was going to continue to rise.” Although her house in the Sunset Lakes community stands at the edge of the Everglades, the Atlantic’s higher elevation prevented it from draining as efficiently as in the past.
“It took a very, very long time to recede,” she said. “Two or three weeks to recede to normal levels.”

The South Florida Water Management District, which operates the big canals that sweep water into the ocean, submitted a funding request to the state this week for fixing the system, with the preliminary list of projects carrying a price tag of more than $1.5 billion. Although expensive, the pumps and other improvements would help restore the efficiency of a system built after World War II that has become more difficult to operate at a time of rising sea levels.

“When ocean water is higher, we cannot discharge, so we close the gates to avoid ocean water coming inside,” said Carolina Maran, district resiliency officer for the South Florida Water Management District. “During Eta, it was much higher than normal. And that means again that we cannot discharge to the ocean and that diminished our capacity to prevent and address flooding.”

1. Kick and recommend. This part

stood out to me because of all it will and does mean:
A NOAA study says global sea levels have gone up 3.4 inches from 1993 to 2019.
In South Florida, estimates from the Southeast Florida Regional Climate Change Compact, which represents local governments, call for sea levels to rise another 10-17 inches by 2040.

2. Miami

My understand is Miami has had to install substantial infrastructure to pump water out of the city. Apparently the storm drains flow backward in storms! Well I don't know what causes that we all know global warming is fake.
