There are now 36 ground depressions in the Lakeside Woodlands Community in Pasco County -- that's up from 20 holes on Tuesday. 

The number of sinkholes in Florida has surged since Hurricane Irma.

Some 400 sinkholes have been reported statewide since Hurricane Irma hit in September.

Anthony Randazzo of the engineering and geology firm Geohazards says water flowing underground during such heavy rain events brings with it clay and sand.

“Once you begin to do this you promote a lack of support for the ground surface to be able to hold or support a structure,” said Randazzo. 

Even though a Florida sinkhole hasn't grown in several days, officials said that the debris-strewn site is still considered dangerous and that residents of five homes remained evacuated Tuesday due to the dangers.

The first public meeting will be held in Polk County for residents to hear more about the safety of drinking water in the wake of a massive sinkhole at a fertilizer plant that's sent millions of gallons of contaminated water into Florida's main aquifer.
