"With Miami Beach set to break ground this year on the most ambitious piece yet of its aggressive anti-flooding project, some homeowners worry that raising streets to keep them dry will cause flooding on their properties.
The city will embark on a $100 million project to raise roads, install pumps and water mains and redo sewer connections during the next two years across a swath of single-family homes in the La Gorce and Lakeview neighborhoods of Mid-Beach. A sizable chunk of a citywide effort estimated to cost $400 to $500 million, the work is meant to keep streets dry in the face of sea level rise.
Along the way, engineers will have to figure out how to smoothly join private property to the public right-of-way, which will be an average of two feet higher than it is now. In some cases, private property that drains excess water into the street will no longer do so, creating a conundrum that public works officials believe could be solved with a new form of public-private partnership."
