Why is my yard wet after rain?

Water is arriving faster than it can leave. Check downspouts dumping near the spot, soil that slopes the wrong way, compacted ground, runoff from next door, and sprinklers running after rain.

Do I need a French drain?

Only after the cheaper causes are ruled out. A French drain is a perforated pipe in wrapped stone, sloped to an outlet the water is allowed to reach. Without an outlet it fills and stays wet.

What should I check first?

Watch the yard during heavy rain. Note where water arrives and ponds, follow each downspout, and check the fall away from the house with a string line.

My basement is wet. Is that a yard problem?

Start with downspouts and the grade at the wall. If the wall stays wet after those are fixed, call a foundation or waterproofing contractor.

Water runs even in dry weather. Why?

That is not rain. Check the irrigation and look for a supply leak by watching the water meter with every tap off. A plumber may be the right call.

Can I drain my water onto a neighbor’s yard?

Do not send it onto their lot. Rules on runoff between properties vary by state and city, so ask your city before any work.

Will a rain garden help?

It can, for roof water you can redirect into soil that soaks it up, set back from the foundation. In a spot that already ponds, it can become a pond.

Yard drainage diagnostic

Pick where the water shows, when it appears and what you know about the grade. You get the first thing to check and who to call.

50% of irrigation water can be wasted EPA WaterSense: “as much as 50 percent of this water is wasted due to overwatering caused by inefficiencies in irrigation methods and systems.” Before blaming the soil, check the sprinklers, the downspouts and the grade.

To fix a wet yard, find where the water comes from before anyone digs. Watch the yard in heavy rain, follow each downspout, check that soil falls away from the house, and turn irrigation off for two weeks. A French drain needs an outlet, and it comes last.

Find where the water comes from before anyone digs

The first question is not how to drain the soil. It is where this water arrives from, and why it lands there.

A roof collects rain and drops it at a few points. Those spots get far more water than the sky delivers. A soil that copes with rain can still pond under a downspout.

Our soil study says so. Its first “not a soil finding” is downspouts on the lawn: “Roof water concentrated at two or four points will pond a well-drained soil. That is a conveyance problem, not a map-unit problem.”

Irrigation counts too. US Environmental Protection Agency, WaterSense: “as much as 50 percent of this water is wasted due to overwatering caused by inefficiencies in irrigation methods and systems”. Standing water the morning after the sprinklers ran is a controller problem.

So work in this order: watch it rain, extend downspouts, fix the grade, and only then consider digging a drain.

Causes that are not a soil problem

From HyreYard’s soil study, which labels this list as its own analysis. The last column is the cheap first move.

What is happening	Why it is not the soil	First move
Downspouts discharging onto the lawn	Roof water concentrated at two or four points will pond a well-drained soil. That is a conveyance problem, not a map-unit problem.	Extend the downspout so it lets go well away from the house and the wet spot, on solid pipe with fall.
The lot was regraded for the slab	Cut-and-fill around a new house can leave a bowl, a reverse slope toward the foundation, or compacted fill that no longer matches the survey map unit.	Check the fall with a string line and a level. Regrading so the soil falls away from the house is earthwork, and it may be the fix.
Compaction from construction or traffic	A well-drained map unit can still perch water in the top six inches if the structure was destroyed. Aeration treats compaction; a French drain does not.	Core aeration and organic matter, repeated over seasons.
A neighbor’s yard, a sidewalk or a street that sheds onto you	Off-site water is a grading or drainage-easement question. The soil survey describes the soil, not the neighbor.	Find where the water crosses your boundary. It is a grading or drainage-easement question, and it may not be yours to solve alone.
An irrigation clock that runs after rain	Standing water the morning after a scheduled watering is not a drainage class.	Turn the clock off, then fix the schedule. A rain sensor or a WaterSense labeled controller stops it recurring.

What a French drain is, and when it fits

What it is. A perforated pipe in washed stone, wrapped in fabric so soil cannot clog it, sloped to an outlet the water is allowed to reach.

The outlet is the design. Daylight on a slope, a permitted storm connection, or a dry well sized to the soil. Without one, the trench fills and the ground stays wet.

When it fits. After downspouts, grade, irrigation and compaction have been ruled out, and the soil or a high water table is the cause.

What it does not fix. Compaction, a reversed grade, or water that runs in dry weather.

What the free soil lookup tells you

USDA NRCS Web Soil Survey shows the mapped soil at your address and two properties that answer “is the ground the problem?”

Drainage class

A scale from excessively drained to very poorly drained. “Somewhat poorly drained” means: Water is removed slowly so that the soil is wet at a shallow depth for significant periods during the growing season. Wetness markedly restricts mesophytic crops unless the soil is artificially drained.

At that end of the scale, the ground is part of the problem, and the question becomes what the site can support.

Hydrologic soil group

Runoff in four groups. Group A: low runoff. Group D: high runoff. On group D, water that lands on the surface tends to stay there.

What it does not tell you

It is a survey map of an area, not your bed after a builder cut, filled and compacted it. It cannot see a downspout or a neighbor’s runoff.

The test in your own yard

Dig a hole about a foot deep in the wet spot. Fill it, let it drain, fill it again and time the drop over an hour or two. Water still standing hours later means the soil is part of it.

How to diagnose it yourself

1
Watch it rain
Where water arrives, where it ponds, how fast it appears and how long it stays. Take photos.
2
Follow every downspout
Including the ones behind shrubs. Note where each lets go and where that water travels.
3
Check the fall with a string line
A reverse slope of an inch or two is hard to see. A line level and a tape settle it.
4
Turn irrigation off for two weeks
If the wet spot dries, the schedule was the cause.
5
Look up the soil and dig a test hole
Web Soil Survey gives drainage class and soil group; the hole tells you about the wet spot itself.
6
Then brief a contractor
You know the mechanism. Ask each bidder where the water will go.

What you build changes where water goes

EPA on developed land: “much of the land surface is covered by buildings, pavement and compacted landscapes. These surfaces do not allow rain and snow melt to soak into the ground which greatly increases the volume and velocity of stormwater runoff”.

The EPA page states the mechanism and does not publish a runoff percentage. We do not publish one either.

Every patio, path and shed base is a new hard surface. Rain that soaked in where it fell now runs somewhere else.

Downstream is someone else’s yard. Delivering your water to a boundary can have legal consequences. Settle where it goes before the work.

Slow it down. A rain garden, a planted swale, or a downspout spread across a wide planted area lowers the peak flow instead of moving it.

What to ask before anyone digs

Where does the water go, and with what fall?
A named outlet and a slope. “It will drain away” is not an outlet.
What did you rule out first?
Downspouts, grade, irrigation and compaction.
Is fabric in the spec?
Without it, soil can silt up the stone.
What happens in a big storm?
The overflow route should be safe and chosen, never toward the foundation.
Are permits or easements involved?
Storm connections, easements and discharge across a boundary can be regulated.
Call 811 before digging
Utilities mark buried lines for free before a trench goes in.
A fix proposed without seeing it rain
A dry-day diagnosis, ours included, is a description, not a finding.

What this diagnostic cannot do

See your yard. It turns three answers into questions and next steps. A site visit in the rain is the diagnosis.

Design a drain. Pipe size, slope, outlet and permits are a designer’s job.

Judge a wet basement. Water through a foundation wall is a foundation question. HyreYard does not install drainage. Checked 5 September 2026.
