Seawalls are built to protect areas of human habitation along the coast against tides, waves, and sea level rise. Of the 63 miles of seawalls in Miami Beach, only three miles are publicly owned. This means that most of the responsibility for replacing seawalls falls on the private homeowner.  While homeowners are not being required by the City to replace seawalls at this time, all new seawalls are being required to be more resilient as per city code. New seawall construction guidelines have been changed to ensure that all new public seawalls can be elevated to a height of 5.7’ NAVD (North American Vertical Datum 1988).
