Sixty-three percent of Alachua County sits in a high sinkhole risk zone. That’s not a statistic to ignore — it’s the ground condition every excavation contractor in this area works on.

The limestone bedrock beneath Alachua is covered in many areas by less than 25 feet of permeable sand. When that thin layer gets disturbed without proper compaction — cut incorrectly, filled loosely, graded without attention to drainage — the Florida Department of Environmental Protection specifically identifies improperly compacted excavation fill as a documented cause of ground subsidence. What looks like a completed job can become a problem the next rainy season.

Human activity has increased sinkhole events in Alachua County by 42% over the past 20 years. Construction and excavation are part of that increase when they’re done without respecting the terrain.

At On Track Land Management, we do earthworks and excavation the way it has to be done here — with site assessment upfront, proper sequencing, and compaction at every lift. We serve the US-441 and Progress Park corridor and residential communities like Turkey Creek with the same standard: work that holds up, because our name is on every job we leave behind.
