Facts About The Florida and Miami-Dade
Limestone Industry
• The highest quality limestone aggregate in Florida comes from western
Miami-Dade, home of White Rock Quarries and other mining operations.
• This area is one of only a few locations in the state able to produce
high quality limestone aggregate products that meet state and national
specifications for cement, concrete, concrete products, and asphalt, which are
needed to build the state’s roads, schools, homes, hospitals, and offices.
• Florida is the third highest consumer
and producer of aggregate products in the nation, consuming 92
million tons of aggregate per year. Of that, 60 million tons comes from western
Miami-Dade.
• The limestone quarries in northwest Miami-Dade contribute significantly
to the region’s long-range environmental protection plans, acting both as a
vital water storage area, and as a buffer between urban areas to the east and
the Florida Everglades to the west.
• Miami-Dade’s limestone industry provides more than 14,000 jobs, has a
$500 million payroll, and pays almost $20 million in local sales and property
taxes each year.
• Miami-Dade’s mining firms and distribution networks have invested more
than $10 billion into this vital industry.
• The mines use the most advanced blasting technology available to fragment
the limestone for processing, with vibration levels well under the established
limits.
