Miami FAQ
Do I need a permit to plant a tree in Miami?
Planting native species typically requires no permit, but removal of any tree larger than the minimum diameter under Ch. 17 requires a permit and replacement. Check the Public Tree Master Plan species list before planting.
Are cool pavements required on driveways?
No. Cool-pavement specifications apply only to city street resurfacing pilots. Private driveways follow Miami 21 lot-coverage and pervious-surface rules but are not required to be reflective.
Miami Gardens FAQ
How do I find a cooling center?
Miami-Dade publishes cooling center locations during heat advisories on its 311 portal and through the Office of Emergency Management notifications.
Is there a heat ordinance for workers?
Florida HB 433 preempts local outdoor heat standards; the county relies on voluntary employer programs and OSHA federal guidance.
