# Standing water in yard fixes in Plano, TX > Standing water in your Plano, TX yard: we work out whether it comes from rain, sprinklers or soil that can't drain, then build the fix that matches the cause. URL: https://clayplanodrainagecompany.com/standing-water-in-yard/ Working out whether a puddle comes from rain, sprinklers or soil that can't drain, then matching the fix: a downspout line, a basin, a drain, a regrade or a pump. Last Updated: November 11, 2026 - **Catch:** downspouts, low spots, side swales - **Carry:** solid pipe at a steady fall - **Release:** to the street, never the neighbor ## Puddles that won’t go away? Standing water is a symptom, not a diagnosis. The same puddle can come from roof water, a low spot, a sprinkler zone or clay that can’t drain, and each one has a different fix. [Clay Plano Drainage Company](https://clayplanodrainagecompany.com/) works out where standing water comes from in yards across Plano and nearby cities, then builds the fix that matches. Sometimes that’s a drain. Sometimes it’s a sprinkler head. > Check the sprinklers first > > If the wet spot is there on days it hasn’t rained, run the sprinkler zone that covers it on its own and watch for broken heads, leaks or overspray. The guide to a [soggy yard with no rain](https://clayplanodrainagecompany.com/guide/soggy-yard-no-rain/) walks through it. ## What happens on the first visit The first question is timing: when the water shows up, and how long it stays. Photos with the date and time on them help more than anything else you can send. - **When it appears.** During the storm, a day later, or on dry days. - **How long it stays.** Hours, days, or all week. - **The probe.** We push a soil probe in around the wet area to see whether the ground below the surface is saturated or dry. - **Upstream.** Downspouts, the patio, the neighbor’s grade and any sprinkler zones that reach the spot. - **The way out.** Spot elevations to find the low point and the fall to an outlet. We explain the cause in plain terms. If two causes overlap, we say which to fix first and why. ## Why water sits on Plano clay Plano’s clay is slow to take in water. Houston Black, under much of central, east and north Plano, absorbs about 0.03 inches an hour, so a one-inch storm can take more than a day to soak in. That slowness turns small features into standing water: - **Flat lots.** Most of Plano sits on 0 to 3 percent slopes, so a dip of an inch or two holds water. - **Compacted soil.** Construction traffic, play sets and worn foot paths press clay tight, and even less soaks in. - **Perched water.** Topsoil or sand laid over clay holds rain in the top layer, because the clay below won’t take it. This is easy to mistake for a high water table, which is less likely on Plano’s clays. - **A low yard.** A lot that sits below the street or its neighbors collects everyone’s runoff. Wet topsoil sitting on dense clay: perched water, not a high water table. ## Matching the fix to the cause Once we know where the water comes from and where it can go, the choice of fix follows. Here’s how the causes line up with the work. | Cause | Fix | | --- | --- | | Roof water dumped in one place | [Downspout lines](https://clayplanodrainagecompany.com/downspout-drainage/) in solid pipe | | Surface water collecting in a low spot | A [catch basin](https://clayplanodrainagecompany.com/catch-basins/) at the true low point | | A shallow bowl or reverse slope | [Regrading](https://clayplanodrainagecompany.com/yard-grading/) the area | | Soil that stays wet after the surface dries | A [French drain](https://clayplanodrainagecompany.com/french-drain-installation/) | | Several sources across the lot | A [whole-yard drainage system](https://clayplanodrainagecompany.com/yard-drainage/) | | No fall to any outlet | A [yard sump and pump](https://clayplanodrainagecompany.com/sump-pump-drainage/) | | Water on dry days | A sprinkler or plumbing repair | A dry well sounds like an easy answer, but in clay this slow it fills and stays full. The guide on whether [dry wells work in clay](https://clayplanodrainagecompany.com/guide/do-dry-wells-work-in-clay/) explains why. ## What standing water does to a yard A puddle that clears in a few hours is just a wet lawn. One that lasts for days starts doing damage, and the damage depends on where it sits. - **In the lawn.** Grass under standing water thins and dies back, and the bare patch holds water even longer next time. - **Underfoot.** Walking or mowing on soaked clay packs it tighter, so less water soaks in at the next storm. - **Beside the house.** Water against the beam soaks the clay under one part of the slab, which [foundation drainage](https://clayplanodrainagecompany.com/foundation-drainage/) is built to stop. - **At the fence and beds.** Constantly wet soil rots fence posts and drowns plant roots. ## What you can check before we visit A little homework narrows the cause before anyone digs. These checks cost nothing and take one storm and one dry day. 1. **Log the timing.** Note when the water appears and when it’s gone, with a photo each time. 2. **Run each sprinkler zone alone** on a dry day and watch the wet spot. 3. **Do a meter test.** With every tap and the sprinklers off, see whether the water meter still moves. 4. **Watch the downspouts** during a heavy rain, and follow where their water goes. 5. **Look uphill.** Note what the neighbor’s yard, patio or driveway sends your way. ## Water from next door If a neighbor’s yard, sprinklers or a new fence line sends water onto yours, part of the fix may sit on their side. - **Water sent over.** A higher yard, a patio or a sprinkler zone that throws water across the line. - **Water held back.** A raised bed, a rock pile or a solid fence along the lot line can dam water on your lot just as surely. - **The rules.** Plano lots are designed to drain to the street, not across each other, and Texas law bars diverting natural flow in a way that damages another property. Many fixes stay on your side of the line, such as a basin and solid pipe that carry the incoming water to your own outlet. The guide to [neighbor water runoff](https://clayplanodrainagecompany.com/guide/neighbor-water-runoff-texas/) explains where the rules draw the line. ## A creek, a floodplain or a drainage problem? A yard near a creek that floods only in the biggest storms may sit in a mapped floodplain. That’s a different question from yard drainage, and the answer changes what can be built. - Water that rises from the creek side and recedes with the creek points to the floodplain. - Water that collects from the house, the roof and the lawn points to drainage. - Both can happen on the same lot. The guide on [floodplain or drainage problems](https://clayplanodrainagecompany.com/guide/floodplain-or-drainage-problem/) shows how to check your address. ## What fixing standing water costs We price standing water as whichever fix the visit calls for, because the cause decides the job. Each fix has its own typical range on its page, and the written estimate shows the one your yard needs. What moves the total is the source of the water, which fix applies, the distance to a legal outlet, whether a pump is needed, and the restoration afterward. - The [drainage cost guide](https://clayplanodrainagecompany.com/guide/drainage-cost-plano/) lays the fixes side by side. - The [drainage assessment](https://clayplanodrainagecompany.com/tools/drainage-assessment/) helps you sort the symptoms before we visit. ## What's included - A visit that pins down when the water appears and how long it stays - A soil probe to tell water on the surface from water held in the ground - A check of sprinkler zones, heads and the controller schedule near the wet area - Spot elevations to find the low point and the fall to an outlet - A look at downspouts, paving and the neighbor's grade upstream - A plain explanation of the cause, and what to rule out next if two causes overlap - A written estimate for the fix that matches ## When does the water show up? | | During or right after the storm | Days after the storm | When it hasn't rained | | --- | --- | --- | --- | | Likely source | Surface runoff from the roof, paving or a higher lot | Soil that can't drain, or water moving through the ground | Sprinklers, a leak or a seep | | What we check | Downspouts, grade and the low point | Soil probe, fall and the outlet | Zones, heads, the controller and the water meter | | Likely fix | Downspout lines, a catch basin or regrading | A French drain or curtain drain | A sprinkler or plumbing repair, not a drain | ## Related resources - [Learn**Is it a floodplain problem or a yard drainage problem?** A flooded back yard by a creek and a flooded back yard on a flat lot look alike from the patio.

Water stands where it arrives faster than it can soak in or run off. In Plano that can be a low spot on slow clay, roof water dumped in one place, a higher lot draining onto yours, or a sprinkler zone. The timing of the puddle tells you which. ### Is standing water in the yard bad for the house? It depends on where it stands. A puddle in open lawn mostly costs you grass. Water that stands against the slab, or soaks one side of the house more than the others, works on the clay under the foundation, and that's worth fixing soon. ### How do I get rid of standing water fast after a storm? Clear any blocked grate or emitter, move downspout extensions away from the low spot and stay off the soaked area so the clay doesn't compact. Don't pump it onto the neighbor's lot. Then note how long it lasts, which tells us what the right fix is. ### How do I stop water puddling in a play area? A play area dug out and filled with mulch or rubber makes a bowl over clay that can't drain. The fix is to give the bowl an exit: a basin or a short drain under the fill with solid pipe to an outlet, or a shallow regrade so it sheds water. ### Could my yard be in a floodplain instead? If the water rises from a creek or comes only in the largest storms, check the plat and the floodplain maps for your address. Floodplain flooding is a different problem from yard drainage, with its own rules, and our floodplain guide explains how to tell them apart. ## Related services - [Service**Yard drainage systems** One planned route that collects roof, surface and soil water from several parts of the yard and carries it in solid pipe to a legal outlet.](https://clayplanodrainagecompany.com/yard-drainage/) - [Service**Catch basins** A grated box set at the lowest point of a lawn, bed edge or patio that takes in surface water and sends it through solid pipe to an outlet.](https://clayplanodrainagecompany.com/catch-basins/) - [Service**Yard sump pumps** An outdoor pump basin that collects yard water on a lot with no downhill path and pushes it through a buried line to the street or another approved outlet.](https://clayplanodrainagecompany.com/sump-pump-drainage/) ## Get an estimate for standing water Tell us where the water stands and when.
