Unlike other parts of the world, we cannot protect our homes with only levees or seawalls: ground water levels are rising and coming up from underneath us through the small holes and cracks in the bedrock.
Of the 63 miles of seawalls in Miami Beach, only 3 miles are publicly owned. A private seawall owner can expect to spend $1000-$1500 per linear foot to bring an old seawall up to code (this is a general rule of thumb of course).
While homeowners are not being required by the City to replace seawalls now, all new seawalls are being required to be more resilient.
New seawall construction guidelines have been changed to ensure that all new seawalls can be elevated to a height of 5.7' NAVD.
To see what the new regulations for seawall construction are like, you can visit the City's new seawall at 23rd and North Bay Road, or the Cherokee Avenue street end in Lakeview.
