On Monday, H-mom sent an email to the Fort Lauderdale Building Department and they came right out, marked it all up with white paint, and then sent a crew on Tuesday to fill it in with gravel and sand.
The crew even named it "SINK HOLE."
Today the hole opened back up and now you can see the landscaping pipes underneath. Looks like it's a hungry Sink Hole.
H-mom sent another e-mail to the city. They are going to need to institute a more aggressive sink-hole-management program.
