A playground surface is specified by what happens when a child falls on it. The grass is the top layer of a safety system, and the layer under it, the shock pad, is the part a cheap quote leaves out.
Playground artificial grass in Miami-Dade is bought by schools, daycare centres, churches, parks departments and parents turning a back garden into a play area. The build differs from a lawn in one fundamental way: the surface has a fall-height rating that depends on the shock-absorbing layer underneath, so the turf cannot be chosen until the equipment height and the required critical fall height are known. Published South Florida bands put sports and play surfaces at 15 to 20 per square foot for material and 12 to 15 per square foot for labour, above a standard landscape lawn, because the pad, the base and the edge detail all cost more.
| Job | Published 2026 range |
|---|---|
| Removal of the existing lawn and debris hauling, added to the installation | 1 - 3 per square foot |
| Excavation and a compacted crushed-rock base, added to the installation | 1 - 3 per square foot |
| Class II road base aggregate | $42 per ton |
| Washed open-graded drainage stone | $52 per ton |
| Non-woven geotextile soil separator placed under the base | $0.48 per square foot |
| Basic grass with silica sand infill, per square foot installed | $9.30 per square foot |
| Rapid-drain grass with zeolite infill, per square foot installed | $12.60 per square foot |
| Standard installation labour | $8.50 per square foot |
| Pet-spec installation labour, deeper dig and edge pinning | $11.50 per square foot |
| Hurricane-rated edge pinning and seam anchoring, where specified | 1 - 2 per square foot |
| Permit allowance, where the jurisdiction requires one | 100 - 500 |
| Spot repairs and small fixes | a few hundred to several thousand depending on scope |
The sequence is fixed. Measure the highest designated play surface on the equipment, decide the critical fall height the surface must meet, then choose a shock pad and a turf plus infill combination that carries that rating together. A turf sold as playground grass without a pad under it is a lawn. Ask any installer for the pad specification and the tested fall height of the assembled system, not the number printed on the turf roll.
Miami-Dade sits on oolitic limestone under a thin layer of sandy fill, and the Krome series mapped across the county is a very gravelly loam that drains very fast (https://soilseries.sc.egov.usda.gov/OSD_Docs/K/Krome.html, HTTP 200). Play areas still need a designed base: a compacted, open-graded aggregate layer with a geotextile separator and a graded fall to an outlet. The wet season runs roughly May to October with short heavy downpours (https://www.weather.gov/mfl/, HTTP 200), and a play surface that ponds is unusable for days and unsafe under a slide.
A playground is usually a smaller area than a lawn, so the fixed costs spread over fewer square feet. Expect the installed price per square foot to sit at the top of the published band, and expect the pad to be the line that moves it most.
Miami Beach is built on reclaimed and filled land over limestone, with a shallow water table that sits close to the surface in the low-lying blocks. Fill drains unevenly, so a turf build here is a drainage design first: grade away from the structure, keep the base open-graded, and plan where the water leaves the lot. The county is mapped on oolitic Miami Limestone, a soft, highly permeable rock that is often within a metre of the surface under a thin layer of sandy fill. The USDA-NRCS Krome series, mapped across Miami-Dade, is a very gravelly loam over limestone that drains very fast (https://soilseries.sc.egov.usda.gov/OSD_Docs/K/Krome.html, HTTP 200). Crews hit rock quickly, so a turf build usually goes up rather than down: a graded, compacted open-graded aggregate base over a geotextile separator, with a positive drainage outlet.
Water reaches Miami Beach through the county system, and the city bills its own customers. Salt is the local variable: yards within a few blocks of the Atlantic or Biscayne Bay take airborne chloride, which attacks low-grade backing and cheap infill long before the face fibres show wear.

If the surface has to meet a critical fall height, yes. The pad and the turf work as one tested system. Ask for the assembled rating rather than the figure printed on the turf.
Published South Florida bands put sports and play material at 15 to 20 per square foot and labour at 12 to 15 per square foot, both above landscape rates. The shock pad is priced by required fall height and quoted separately.
A dark-infill synthetic surface in full sun can reach the 140 to 160 F range on a hot day. Use lighter infill, add shade where the equipment allows, and hose the surface before afternoon use.
