Southern Miami-Dade County serves as a critical buffer zone located between two national parks. In this project, we examine the process of rapid suburbanization as agricultural lands transition to residential development. Strategies to slow suburbanization at local and regional scales include growth management policies and zoning regulations. In particular, zoning ordinances serve the primary method for lessening and preventing the conversion of agricultural and forested lands-though zoning has also been implicated in increased landscape fragmentation. To understand the role of zoning in shaping (or not) the conversion of agricultural lands into residential lands in southern Miami-Dade County, FCE researchers have been analyzing parcel-scale zoning data (supplied by Miami-Dade County, Dept. of Planning and Zoning) using GIS.
