HOUSTON, Texas (NBC) - Volunteers in Houston are working around the clock to reopen Buffalo Bayou Park.
The recreation area took a huge hit after Hurricane Harvey.
Workers are now taking a bite out of mountains of sand that was dumped in the park.
The park is designed to flood, but nothing prepared it for Harvey.
Harvey dumped more than 70,000 cubic yards of silt in the park.
In all, it will take more than 5,000 truck loads to pick up and remove the sand.
The work is estimated to take about ten to twelve weeks.
Ann Olson is the president of the Buffalo Bayou partnership.
Olson says there could be changes to the lighting system and to the dog park.
Olson says volunteers have been a big help at picking up the pieces.
