Platting and Traffic Concurrency Review

Platting is the mandatory legal process of dividing, subdividing or combining land into officially recorded lots, blocks and parcels, typically required before obtaining building permits for new developments. It maps out property boundaries, streets and easements, ensuring compliance with the Miami-Dade County's Subdivision Code.

Platting creates legally buildable sites, establishes accurate legal descriptions and ensures proper infrastructure such as roads and utilities.

The Platting process involves submitting a tentative plat for review, followed by a final plat that, once approved by the County Commission, is recorded in public records. The Plat Committee reviews applications every Friday to ensure compliance with zoning and traffic regulations. For certain smaller subdivisions that do not require new streets or extensive improvements, a Waiver of Plat may be approved, which becomes a legal building site 10 days after approval.

Why platting is required

The process is often required to ensure that new developments do not negatively impact existing traffic and infrastructure.

• Legality: You generally cannot obtain building permits or sell subdivided property in unincorporated Miami-Dade without an approved plat or waiver.
• Infrastructure: It ensures that new developments have proper access to utilities (FPL, AT&T, etc.), adequate traffic capacity, and integrated drainage systems.
• Public Record: Plats are recorded in the public records of Miami-Dade County, providing a clear "blueprint" for property ownership and preventing future boundary disputes.

Submittal requirements: A survey, legal description and sometimes a traffic concurrency review are necessary to evaluate the development's impact.
