Cutler Bay is an incorporated town in Miami-Dade County, Florida established in 2005, with a population of approximately 43,718 as of 2019.
The borders were established as running from SW 184th Street (Eureka Dr) east of US 1 to the coast, and north of Black Point Marina, at 25°34′50″N 80°20′48″W. The town's boundaries include the northeast section of Biscayne National Park, areas formerly known as Cutler Ridge to the west, as well as the neighborhood and former CDP of Lakes by the Bay to the east.
In August 1992, Hurricane Andrew made landfall near the area and caused extensive destruction. Lakes by the Bay was one of the areas of Miami most affected by Hurricane Andrew, and most homes and businesses in the area were completely destroyed. The area has since been rebuilt.
Cutler Bay is located just west of Biscayne Bay at 25°34′58″N 80°20′48″W.
According to the United States Census Bureau, the CDP had a total area of 4.9 square miles (13 km2). 4.8 square miles (12 km2) of it is land and 0.1 square miles (0.26 km2) of it (2.26%) is water. The total square miles is ten.
Cutler Ridge, an ancient coral formation, stretches from south Miami, where it rises approximately 22 feet, through the Cutler Bay area, at a height of 14 feet, to Homestead, Florida, where it is about 8 feet. Cutler Ridge has been incorporated into the hurricane emergency plans for the area as lands east of the ridge are subject to storm surge, but areas west of the ridge would generally be protected.
Due to Cutler Bay's position in a flat, low-lying coastal wetland area on Biscayne Bay, the area is prone to flooding.
