If you’re a children’s park solutions provider like me, you already know that designing spaces where kids can run, climb, and laugh is equal parts creativity and responsibility. But one of the most underdiscussed, yet critical, parts of that work is flood-proofing. Last year, we wrapped up a project for a small suburban park that had suffered two flash floods in three years—each time, the playground equipment was waterlogged, the mulch turned to muck, and the park was closed for a month or more. That’s when I realized flood-proofing for children’s parks isn’t just about keeping sand dry; it’s about protecting memories, cutting down operational costs, and making spaces kids can enjoy year-round. Over the past two years, we’ve refined a set of science-backed, kid-friendly flood-proofing measures that work for playgrounds of all sizes, and I want to share what we’ve learned. Children Park Solutions
First, let’s talk about the biggest flood risk for most children’s parks: their location. When a school or city hires us to build a new playground, we don’t just look at how much fun the slides look or how many kids they can fit. We pull 50 years of local flood data—from the National Weather Service, FEMA, and even local historical societies that track heavy rains and river crests. For example, a park in a low-lying neighborhood might be at risk from slow-rising river floods, while a park on a hill but near a creek could face flash floods after a summer thunderstorm. The key here is that one size doesn’t fit all. Last year, we worked on a project in a small town that sat between two creeks, with a 100-year flood zone designation. We didn’t just pick a bunch of expensive materials and call it done; we mapped the exact flood paths so every solution we used was targeted to where water would actually flow. That’s the foundation of any good flood-proofing plan: know your water before you build your park.
Next, the playground surfaces themselves. If you’ve ever stood in a playground after a heavy rain, you know that some surfaces turn into mud, while others drain almost instantly. For flood-prone parks, we avoid loose mulch and sand, which can wash away in a hard rain and get carried into nearby waterways—plus, they turn to muck that’s impossible to clean. Instead, we use permeable safety surfaces. The science here is simple: these surfaces are made with small, interconnected gaps that let water seep through instead of running off. We tested a few different types for a park in Tampa, which gets frequent tropical storms. The permeable rubber tiles we installed can let through 15 gallons of water per square foot per minute—way more than the average heavy downpour, which is about 1.5 gallons per square foot per minute. The best part? They’re still soft enough for kids to fall on, so we didn’t have to compromise on safety. We also add a gentle slope to all surfaces—usually 1% to 2%—that directs water toward designated drainage areas, not toward the play structures or picnic spots. That small slope makes a huge difference: instead of water pooling under the swing sets (which would make them slippery and hard to use), it flows slowly to the edges of the park and into the ground.
Then there’s the play equipment, which is the heart of any children’s park. Even if the surface can drain well, if a metal swing set or wooden playhouse is sitting in water, it will rust or rot over time. We recently switched all our metal equipment to hot-dipped galvanized steel, which is coated in a thick layer of zinc that resists rust even when it’s submerged in water for days. For wooden structures—like small tree houses or picnic shelters near the play area—we use pressure-treated wood that’s rated for ground contact, so it can handle being wet without rotting. We also elevate the base of every piece of equipment at least 12 inches above the highest expected flood level, per FEMA guidelines. That’s not just a rule; when we installed the first elevated swing set in that Tampa park, we tested it with a garden hose spraying water hard at the base for two hours, and the stand never got wet. We also add waterproof seals to all moving parts—like swing chains, slide tracks, and climbing wall hinges—so water can’t get inside and cause them to seize up. Last year, during a minor flood in Cincinnati, that’s exactly what happened: a nearby park with our equipment was able to re-open three days after the water receded, while the other park in the neighborhood had broken swing chains and waiting two weeks for parts.
Drainage is another critical piece, and it’s not just about putting in a few pipes. For parks that face slow-rising floods, we install underground French drains along the perimeter. A French drain is just a trench filled with gravel, with a perforated pipe at the bottom that carries water away from the park to a nearby storm drain or low-lying area. For flash-flood-prone parks—like the one in that small town between two creeks—we add dry swales, which are shallow, grass-filled ditches that can hold extra water during a storm. Kids love them too; we’ve had parents tell us their children splash in the swales after heavy rains, which turns a flood mitigation tool into a fun play spot. We also make sure all drainage systems are clear of debris—leaves, sticks, and trash can block pipes and make flooding worse, so we add simple, kid-safe grates over all drains. Kids can climb on them, and they keep big debris out. We never want to build something that feels like a barrier between kids and fun, so we design every drainage feature to be part of the park, not an afterthought.
Another thing most people don’t think about is utilities. If a flood knocks out electricity to the park, or if water gets into the electrical outlets for things like the spray ground or lighting, the park can be closed for weeks. For all our projects, we install electrical outlets and control panels at least 18 inches above the highest expected flood level, and we use GFCI (ground fault circuit interrupter) outlets that cut power if they get wet. We also run all underground utilities—water, gas, and electricity—in PVC pipes, which are resistant to water damage and corrosion. Last year, a park we built in Indianapolis had a major thunderstorm that dropped 7 inches of rain in two hours. Other nearby parks had to shut down because their lighting panels were flooded, but our park was fully operational the next morning, because all utilities were elevated and protected.
Kid-friendly design is non-negotiable, too. I’ve walked into parks where flood-proofing looks like a construction zone—big pipes sticking out, steep slopes that are hard for little kids to climb. That’s not acceptable. Every flood-proof measure we add has to be something kids can interact with or play around. For example, the permeable rubber tiles come in bright, fun colors, so they look like a design choice, not a functional one. The dry swales are edged with small rocks that kids can climb on or skip stones across. Even the elevated play bases are made to look like small platforms, like a tree house on stilts, so kids think it’s just a cool feature, not something that keeps them safe. We did a survey of parents at that Tampa park a year after it opened, and 92% said they didn’t even notice the flood-proofing features—they just thought the park was really well-designed. That’s the goal: protect the park without making it feel like a defense system.
We also work closely with cities and park districts to create emergency plans, because even the best flood-proofing measures can’t keep a park completely dry during a major 100-year flood. We help them create a checklist: what to move (like benches and picnic tables), how to turn off utilities, and when to close the park to keep kids safe. We also offer annual maintenance checks—we go out every spring before rainy season to clean the drains, tighten equipment bolts, and make sure the permeable surfaces aren’t clogged with dirt or leaves. That small step makes a big difference; last year, a park in Cleveland had a small backup because their drains were clogged with leaves, so we went out the same day and cleared them, and the park was back to normal within a few hours.
For any children’s park solutions provider, the bottom line is that we’re building spaces for families to make memories. A flood can take that away for months, even years. But with the right research, targeted design, and kid-friendly features, we can make parks that are fun, safe, and resilient. If you’re a city planner, park director, or business owner looking to build a new children’s park or update an existing one, and you want to talk through flood-proofing solutions that fit your space, feel free to reach out. We’ve worked with parks of all sizes, from small neighborhood spots to larger community centers, and we’re here to help you create a space that lasts.
