Gravel, Stone and Soil Delivery in Kissimmee, FL

Storms over a city gauge

The NOAA normals station at Kissimmee 2, FL, about 2 miles away, gives the weather averages for this ZIP. It records 52.6 inches of precipitation in an average year and 0.0 inches of snow. Summer storms can bring a large share of that in a few hours, and on flat, wet sand the water has few places to go.^[1]

Freezing nights are scarce at Kissimmee 2. That gauge logs 3 days in an average year when the low drops to 32 F or below. January 28 is its median last freeze date, and January 6 is its median first freeze date. Base work and planting can go on through most of the year, so long as the ground is not flooded.^[1]

Heavy rain also moves mulch and loose stone. Edging around beds and paths holds them in place when storm water runs across a flat yard, and a slight lip at the edge of a drive keeps its top stone from floating into the lawn.^[1]

Wait a day or two after a heavy storm before compacting a new base. Sand that is saturated will not pack firmly, and a base rolled over wet ground stays soft and ruts in the next rain.^[1]

Myakka sand and the water table

The USDA soil survey maps Myakka-Urban land complex at the ZIP's center point. Myakka makes up 50 percent of the map unit, and urban land, ground that is paved, graded or built over, makes up 40 percent.^[2]

Myakka is rated poorly drained. Its hydrologic group is A/D, a split rating. With the water table up, the soil takes water slowly and sheds a lot of it, like group D. Once ditches or pipes have lowered the water, it soaks rain in quickly, like group A. Fine sand forms its top mineral layer.^[2]

Urban land at 40 percent of the map unit means much of the ground near the center point has already been graded or filled. Old fill can be firmer or softer than the native sand, so a test hole before a big pad shows what the base will sit on.^[2]

Shrink-swell in the top meter rates low, at 1.5 percent, so the soil does not heave. The challenge is wet sand that loses strength. Myakka soils can hold a dark, hard layer some way below the surface that slows water moving down, which adds to the wet feel in the rainy season.^[2]

The geologic map shows Undifferentiated sediments at the same point, made of sand, clay, silt, marl, peat and gravel, with a Pleistocene age. Those layers vary from place to place under the city. The ground at the center point stands 70 feet above sea level.^[3],[4]

Building up instead of down

Graded Aggregate Base is the stone layer the Florida Department of Transportation names in Section 204 of its Standard Specifications for Road and Bridge Construction (FY 2026-27). Highway crews here place it on built-up fill when the ground is wet, and the same rule works for a home drive or a pad.^[5]

Peel off the grass and dark topsoil first. Then lift the work area with Fill Sand or Fill Dirt, packed in layers, until the finished top will stand clear of the lawn around it. A woven fabric across that fill holds the stone up out of the wet sand. Road Base or Crushed Concrete then goes on in thin lifts, each one compacted before the next.^[2]

Plan the outlet before the base goes in. On ground this flat, water from a drive needs a low place to drain to, such as the street gutter, a ditch or a stone-filled dry well at the far side of the lot. Without one, the water runs off the drive and then sits at its edge, softening the base from the side.^[1],[2]

Top it with a thin layer of 3/4" Crushed Stone or #57 Crushed Stone. Crown the surface so rain leaves at the sides, and leave a shallow swale or a strip of Drain Rock along the low edge. A pad for a shed, a trailer or a hot tub follows the same steps on a smaller scale.^[1]

Beds and small yards

Roots do poorly in waterlogged sand. Raised beds of Garden Soil, or Topsoil mixed with Compost, lift plants above the wet season water table. The Compost also holds water and nutrients through dry spells, when fine sand drains quickly.^[2]

Shredded mulch is the usual bed cover. Brown Shredded Mulch, Black Shredded Mulch and Red Mulch knit together and stay in place in heavy rain. Wood Chips under trees break down slowly and feed the soil. Keep any mulch a few inches from siding and trunks.^[1]

In a small yard, a stone patio or a gravel seating area turns a soggy patch into usable space. Raise it a few inches, lay fabric, and use #89 Crushed Stone or Pea Gravel over a compacted base. River Rock along the drip line of the roof keeps falling water from digging into the sand.^[2]

Choosing between Fill Sand and Fill Dirt

Fill also changes how a lot drains next door. Raising one corner of a yard can push runoff onto the neighbor's ground, so grade new fill toward the street or a swale on your own property.^[2]

Raising ground is part of most jobs here, and two fill materials cover it. Fill Sand drains fast and compacts firmly in thin, wetted lifts. It suits the bed under a pad, a paver patio or a drive, where water must pass through and the surface must stay level.^[2]

Fill Dirt holds together better and resists washing, so it suits raising a low part of a lawn or building up a berm. It drains more slowly than Fill Sand. Top it with a few inches of Topsoil if grass or plants will grow on it.^[2]

Whichever fill is used, place it in thin layers and compact each one. A thick layer dumped at once settles unevenly for months, and on wet ground those dips fill with water after every storm.^[1]

Homes in ZIP 34741 and Kissimmee

ZIP 34741 holds 22,386 housing units in the Census count. Only 26 percent of them are detached single-family houses. Owners occupy 33 percent of the lived-in homes, so most residents rent. Half the homes in the ZIP went up before 1992.^[6]

Citywide, Kissimmee has 30,926 housing units, and 46 percent of those are detached houses. The city's median build year matches the ZIP at 1992. Apartments, townhomes and condos fill out the rest, and their usual orders are mulch for shared beds, stone for walkways and fill for low spots.^[6]
