What would happen if an Ian-like storm makes landfall on Biscayne Bay (Miami: homes)

What happens if a 15-foot storm surge impacts Miami-Dade?


<<
Public concern about hurricanes is centered mostly on wind damage, experts note. But a large, slow-moving Category 4 storm like Hurricane Ian would push a catastrophic surge across much of coastal Miami-Dade many times worse — and extending much farther inland — than Irma’s, National Hurricane Center surge risk maps show.


And that’s something that many experts say Miami-Dade remains in many respects unprepared for, both psychologically and physically, as we continue to add residents and pile on denser development in vulnerable areas from Miami Beach to Brickell and South Miami-Dade amid seas and underground water tables swollen by climate change....



But even the best solutions will at most reduce, but not block, the impact of surge from a major storm. Many of those are years away. And even then, they will only buy around 30 years of time before rising seas will overwhelm the defenses once again. Meanwhile, thousands of older homes and buildings at ground level remain highly vulnerable to surge.>>

The article explains that due to Bay of Biscayne's shallow depth, a large storm surge would imperil coastal communities such as Homestead, Cutler Bay, Palmetto Bay, Pinecrest, Coconut Grove, and Gables by the Sea.


The article details how change in paths of both Hurricanes Irma and Ian spared Miami-Dade much more significant damage.


This paragraph from the article analyzes the impact of a Cat 4 hurricane, not a Cat 5.


<<The Hurricane Center surge maps show a Cat 4 storm would send crashing waters for miles inland in some areas. Surging saltwater could overwhelm the east side of Miami Shores and Miami’s Upper East Side, overflow the Miami River all the way to Hialeah, devastate Coral Gables neighborhoods east of Old Cutler Road with more than nine feet of water, flood Pinecrest and invade farmland east of Homestead.>>


The article also emphasizes hurricane preparedness long before a hurricane threats manifests itself.
