Miami-Dade County Department of Planning
The Miami-Dade County Department of Planning serves as the primary agency responsible for guiding land use, population growth, and long-range development across one of the most complex urban regions in the United States. This page covers the department's legal mandate, how it processes applications and formulates policy, the most common situations in which residents and developers interact with it, and the boundaries of its authority relative to other agencies and municipalities. Understanding the department's role is essential for anyone navigating development approvals, zoning amendments, or comprehensive plan updates in Miami-Dade.
Definition and scope
The Miami-Dade County Department of Planning operates under the authority of the Miami-Dade County Charter and Florida's Community Planning Act (Chapter 163, Florida Statutes). The department is responsible for administering the Miami-Dade Comprehensive Development Master Plan (CDMP), the foundational land use policy document that governs how approximately 2,431 square miles of county territory — both incorporated and unincorporated areas — are designated and developed over time.
The department's core functions include:
- Preparing and maintaining the CDMP and its land use element amendments
- Reviewing land use applications for consistency with adopted policy
- Conducting environmental and demographic impact analysis
- Providing technical support to the Miami-Dade Board of County Commissioners
- Coordinating with state and regional planning bodies, including the South Florida Regional Planning Council
Scope limitations: The department's direct regulatory authority applies primarily to unincorporated Miami-Dade County and to countywide plan amendments affecting all municipalities. It does not govern zoning decisions within the 34 incorporated municipalities — such as the City of Miami, Miami Beach, Coral Gables, or Hialeah — which each maintain their own local planning functions. However, all municipal plans must be consistent with the CDMP under Florida law, giving the county's planning framework indirect influence over every incorporated jurisdiction.
How it works
Applications for CDMP land use amendments follow a structured review cycle. Miami-Dade County holds two amendment cycles per calendar year — a Small-Scale cycle for parcels under 10 acres and a Large-Scale cycle for broader policy changes. Each cycle involves:
- Pre-application consultation between the applicant and department staff
- Technical sufficiency review to confirm the application package meets submission requirements
- Interagency review coordinating with departments including Miami-Dade Environmental Regulation, Miami-Dade Water and Sewer, and Miami-Dade Transportation Planning Organization
- Public hearings before the Community Zoning Appeals Board and the Board of County Commissioners
- State review by the Florida Department of Economic Opportunity for large-scale amendments that meet statutory thresholds
For rezonings in unincorporated areas, the department reviews applications for consistency with the CDMP's land use designation before the Zoning Hearing Master or the Board of County Commissioners takes final action. Zoning decisions in unincorporated Miami-Dade are governed by the Miami-Dade County Zoning Code, which the department administers jointly with the Department of Regulatory and Economic Resources (RER).
The department also produces the annual Miami-Dade County Budget-aligned capital improvement element, which reconciles five-year infrastructure investment schedules with concurrency requirements — the legal obligation to ensure roads, schools, parks, and utilities can support proposed development before approvals are issued.
Common scenarios
Three situations account for the majority of public interactions with the Department of Planning:
CDMP land use amendment requests — Property owners or developers seeking to change a parcel's land use designation from, for example, Low Density Residential to Business and Office submit amendment applications during the biannual cycle. Staff analysts evaluate criteria including traffic impact, environmental sensitivity, proximity to transit, and consistency with adopted policy objectives.
Developments of Regional Impact (DRI) — Projects exceeding thresholds established under Chapter 380, Florida Statutes — such as a retail center exceeding 400,000 square feet in Miami-Dade — trigger a DRI review coordinated by the department and the South Florida Regional Planning Council. These reviews examine regional transportation, housing, and environmental effects beyond the project site.
Evaluation and Appraisal Reports (EAR) — Florida law requires each county to periodically evaluate its comprehensive plan against current conditions and state requirements. The department prepares the EAR, which can trigger mandatory plan updates affecting future development patterns countywide.
A fourth common point of contact occurs when property owners in unincorporated areas seek site-specific rezoning. The department issues a staff report analyzing CDMP consistency, which becomes part of the public record before the hearing examiner's recommendation and the commission's final vote.
Decision boundaries
The Department of Planning makes recommendations — it does not issue final approvals autonomously. Decision authority is distributed across several bodies:
| Decision type | Recommending body | Final authority |
|---|---|---|
| CDMP large-scale amendment | Department of Planning | Board of County Commissioners + Florida DEO |
| CDMP small-scale amendment | Department of Planning | Board of County Commissioners |
| Unincorporated rezoning | Department of Planning / Zoning Hearing Master | Board of County Commissioners |
| DRI development order | Department of Planning / SFRC | Board of County Commissioners |
The department does not have authority over building permits, which fall under the jurisdiction of Miami-Dade Building Permits and Inspections. It does not administer affordable housing finance programs, which are handled by Miami-Dade Public Housing and Community Development, though planning staff coordinate with that department on housing element compliance.
The department's mandate also does not extend to Community Redevelopment Agencies, which operate under separate enabling legislation and boards, or to the Miami Urban Development Authority. Climate-related planning overlaps with the Miami-Dade Climate Resilience Office, with the two offices coordinating on sea level rise projections embedded in the CDMP's coastal management element.
