The short answer: excavate, lay 4 to 6 inches of compacted base, top with 3 to 4 inches of surface stone, crown it, and edge it. Most failed gravel driveways skip one of those steps: no base, no crown, or no edge restraint. Get the layers right and a gravel driveway handles South Florida rain and daily traffic for years with light maintenance.
Step 1: Plan the layout and check the rules
Mark the driveway footprint with stakes and string, keeping it at least a foot wider than the tire tracks on each side. Before you dig, check two things: underground utilities (call 811) and your HOA. Many South Florida HOAs restrict driveway materials and colors, and some prohibit loose stone entirely. Our HOA delivery guide covers the logistics side once the design is approved.
Step 2: Excavate and shape the subgrade
Remove grass, roots, and soft topsoil down to firm ground, usually 8 to 10 inches below the finished surface height. Shape the subgrade with a slight crown or cross-slope so water runs off instead of sitting under your base. On soft or mucky soil, lay geotextile fabric now: it keeps the base from sinking into the subgrade over time. On firm sand it is optional.
Step 3: Lay and compact the base
Spread crusher run or FDOT limerock base in lifts no thicker than 3 inches, watering and compacting each lift with a plate compactor or roller. Target 4 to 6 inches of compacted base. This layer is the structural heart of the driveway: it spreads the weight of vehicles and keeps the surface stone from punching into soft ground. Do not substitute clean #57 stone here; it never locks together.
Step 4: Add the surface layer
Top the compacted base with 3 to 4 inches of surface stone. Crusher run is the best all-around surface: it compacts, drains reasonably, and looks like a proper driveway. Asphalt millings are a solid budget pick that knit together in Florida heat. Spread evenly, then compact once more. Our best driveway material guide compares every option in detail.
Step 5: Crown, edges, and drainage
Crown the finished surface so the center sits an inch or two higher than the edges, or slope it to one side; standing water is what kills stone driveways. Install edge restraint (pavers, timbers, or a concrete ribbon) so tires do not push the edges outward. If the lot holds water, add a trench drain with #57 stone along the low side to carry runoff away.
Ordering the materials
Measure length by width by depth in feet and divide by 27 for cubic yards, then add about 20 percent extra for compaction loss on the base layers. Our material calculator runs the numbers, and the tons vs cubic yards guide explains weight conversions.
