Playground site preparation takes two to six weeks on most commercial projects and comes down to five jobs: assess the site, confirm compliance, clear and level the footprint, build the sub-base and drainage, and then install surfacing that matches your equipment's fall height. Skip any one of them, and the bill shows up later as standing water, a failed inspection, or an install crew waiting on a permit.
This guide walks through each step in the order a professional installer would tackle it. It's written for parks directors, school administrators, and childcare operators managing a first install.
Start with a comprehensive site assessment
Measure before you design, not after. A play structure needs its own footprint plus a use zone extending at least 6 feet in every direction under ASTM International standard F1487, so a 30 by 40 foot play structure really needs about 42 by 52 feet of usable ground.
A site assessment tells you what you're working with before anyone quotes a price. Here's what to look at:
Measure the total square footage first. Confirm the space holds your layout, every use zone, and enough room for kids to walk around the outside without cutting through the fall area.
Test the soil if the ground was ever farmland, fill, or pavement. A geotechnical analysis shows whether you need extra sub-base depth or reinforcement to keep footings from settling.
Walk the slope during or after a heavy rain. Low spots that hold water for more than a few hours will hold water under your surfacing too.
Map every obstruction above and below the ground. Trees, root systems, buried rubble, and old footings all change the excavation plan.
Two hours spent measuring and probing usually saves a change order. Design revisions are cheap on paper and expensive once the crew is mobilized.
Call 811 before anyone breaks ground
Call 811 or your state's one-call center at least two to three business days before excavation. Locators come out and mark gas, water, electric, and telecom lines in the public right-of-way at no cost to you.
That call doesn't cover everything on your property. Irrigation lines, landscape lighting, septic laterals, and old sprinkler runs are private utilities, and you're responsible for locating those yourself or hiring a private locator. Playground footings often go 24 to 36 inches deep, which is exactly the range where irrigation and low-voltage wiring live.
Confirm compliance with safety standards and local codes
Four sets of rules govern a public playground install, and your site plan should satisfy all four before the first delivery truck arrives.
ASTM F1487 sets the performance specifications for public-use equipment. It defines use zones, fall heights, and entrapment limits, including openings that must measure either under 3.5 inches or over 9 inches so a child's head can't get caught.
The Consumer Product Safety Commission (CPSC) publishes the Public Playground Safety Handbook. It's the practical reference for layout, spacing, and surfacing depth, and inspectors cite it constantly.
The Americans with Disabilities Act (ADA) requires accessible routes into and through the play area. That means a firm, stable surface from the parking lot to the equipment, plus accessible play components that a child using a mobility device can actually reach.
Local codes and permits vary by municipality. Some cities require a stormwater review, some want a site plan signed by an engineer, and some inspect after installation before the playground can open.
Having a Certified Playground Safety Inspector (CPSI) review your drawings before construction is the cheapest insurance in the process. Falls account for the majority of the roughly 200,000 playground injuries treated in United States emergency rooms each year, and most of those trace back to surfacing or layout decisions made at this stage.
Clear and level the installation footprint
Clear the full footprint plus a working margin of about 5 feet, then grade it flat. Crews need room to stage components, and a tree stump 3 feet outside the use zone still blocks a Bobcat.
Clearing means removing debris, vegetation, root systems, and any remnants of a previous structure. Old concrete footings are the usual surprise; they turn up right where a new upright needs to go.
Grading comes next. Machine-grade the area to a consistent plane, then verify slope with a laser level rather than by eye. ADA accessible routes cap running slope at 1:20 and cross slope at 1:48, so the tolerances are tighter than most people expect.
Finish by staking out each piece of equipment and its use zone with marking paint or flags. Seeing the footprint at full scale catches spacing problems while they're still free to fix.
Prepare the sub-base and drainage systems
Sub-base preparation
Plan on 4 to 6 inches of compacted crushed stone, usually a 3/4 inch clean aggregate, under loose-fill or poured surfacing. Compact it in lifts with a plate compactor so it doesn't settle unevenly in year two.
Set your playground border at this stage while the grade is still open. Edging holds loose-fill material inside the play area and keeps the perimeter from creeping outward every time someone runs through it.
Drainage considerations
Grade the finished sub-base to fall away from the playground at 1 to 2 percent, roughly 1/8 to 1/4 inch of drop per foot. That's enough to move water without creating a slope kids can feel.
If the site sits in a low area or has heavy clay soil, surface grading alone won't do it. French drains, drain tile, or a dry well tied into the existing storm system move water off the site instead of parking it under your surfacing.
Select and install safety surfacing for your fall heights
Match surfacing to the highest designated play surface on your equipment, not to your budget. CPSC recommends 9 inches of compressed loose-fill material for fall heights up to 10 feet, which means installing loose fill at about 12 inches so it settles into compliance.
Playground surfacing options each trade cost against maintenance:
Poured-in-place rubber costs the most up front and the least in upkeep. It's the usual pick for high-traffic sites and for meeting ADA accessible route requirements without extra work.
Rubber tiles install in modules and replace one panel at a time. Schools and urban sites like them because a damaged section doesn't mean redoing the whole surface.
Engineered wood fiber is the most affordable accessible option. It needs raking and topping off, typically once or twice a year, to hold its depth.
Synthetic turf with a shock pad looks like grass and drains fast. Surface temperature is the tradeoff in hot climates.
Whatever you choose, install it to the manufacturer's specifications. Depth, base preparation, and drainage all appear in warranty language, and shortcuts void coverage on the one component that exists to prevent injuries.
Plan your playground installation with AAA State of Play
Good playground site preparation is what separates a play space that lasts 20 years from one that needs drainage work in year three. AAA State of Play helps parks, schools, and childcare centers plan the site, choose commercial-grade equipment, and get the surfacing right the first time.
