The Oleta State Recreation Area and Mangrove Preserve, located between NE 135 Street and NE 163 Street and east of U.S. Highway 1, has been designated as Environmentally Sensitive Land. These undisturbed natural areas of North Miami act as a natural storage area for flood waters; this helps reduce the possibility of flooding to nearby residences while helping to recharge the groundwater aquifer. Please help keep this area natural and beautiful by reporting any illegal dumping and littering violations to the City’s Code Compliance Department at 305-895-9832 or Miami-Dade County at 311.
