If standing water in your yard is still there 2 or 3 hours after rain or watering, the Washington State University (WSU) Extension home lawn guide calls that a drainage problem. It says the yard may need subsurface tile drainage. The guide is general, not written for Florida.
Fixing a yard that won't drain after rain starts with finding where the water comes from and where it can go. UF/IFAS names three fixes for a wet spot: add soil to raise it, put in a new drain to divert the water, or build a rain garden. A French drain averages about $5,000 nationally, from $500 for minimal work up to $18,000, says the Bob Vila French drain guide updated in 2024. Your Tampa price comes from a written price after the crew comes out and measures.
How to tell a drainage problem from one wet week
Time the puddle
Start with a clock. After the next rain, note when the water stops falling and how long the low spot holds water. The WSU threshold is 2 to 3 hours.
If puddles in the lawn never dry, write down whether it rained, whether the sprinklers ran, and what day it was. Tampa water customers may water lawns once a week, on a day set by the last digit of the house number, and only from midnight to 4 a.m. or 8 p.m. to 11:59 p.m., according to the City of Tampa Water Department. Ask yourself whether the puddle follows rain or follows your sprinkler day.
Read the weeds
UF/IFAS says sedges, doveweed, dollarweed and eclipta point to soggy soil, and that they may signal a sprinkler leak or poor drainage. For dollarweed, UF/IFAS says it usually means overwatering or a naturally wet spot. A patch of these weeds sitting where water collects is a clue worth showing the crew.
Count the rain
NOAA's climate normals for Tampa International Airport show 49.48 inches of rain a year, with about 69 days a year at a tenth of an inch or more. June through September brings 30.24 inches, about 61% of the year's rain, and August is the wettest month at 9.03 inches in a normal year. The National Weather Service dates the rainy season in the Tampa Bay area from May 25 to October 10. November, the driest month, averages 1.40 inches, so note which season your puddles show up in.
What to check yourself
- Push a tool into the soil in the wet spot and in a dry part of the yard, and compare.
- Note which weeds grow where the water sits.
- Check your sprinkler's rain shutoff. Florida law requires every automatic lawn sprinkler system to have working technology that stops it when there is enough moisture, and a licensed contractor working on a system must test it and fix or add one. A rain sensor costs $10 to $100 nationally, according to the Bob Vila sprinkler guide.
- Skip watering after rain. UF/IFAS FAWN says that after 0.3 inch of rain in 24 hours, or 1 inch in 3 days, irrigation may not be needed that day.
Before anyone digs, know this: Florida law requires a call to Sunshine 811 at least 2 full business days before digging, and the locate ticket is good for 30 calendar days.
Why water stands in a Tampa yard
A water table close to the surface
UF/IFAS describes many Florida flatwoods soils as having a weakly cemented organic hardpan, usually 12 to 40 inches down, with a water table that rises to within 5 to 20 inches of the surface. The USDA calls Myakka fine sand, Florida's state soil, poorly or very poorly drained, with the water table less than 18 inches down for 1 to 4 months in most years. Both are statewide descriptions, not a survey of any one lot, but they help explain why some Tampa yards pond after rain.
Compacted soil
UF/IFAS Extension in Hillsborough County says urban development in Tampa and Hillsborough County often leaves compacted, nutrient-poor sandy soil.
A simple test from UF/IFAS: if you struggle to push a tool more than a few inches into the soil, the root zone is likely compacted, which leads to shallow roots and poor drainage. Our page on compacted soil in a lawn covers that problem on its own.
A low spot or a grade that sends water the wrong way
For a new lawn, UF/IFAS Hillsborough County says to grade the soil 1% to 2% away from buildings or toward drains, and to avoid slopes steeper than 3 to 1. If a low spot in the yard holds water after every storm, ask a crew what the slope does between your house, the low spot and the street.
Runoff with nowhere to go
The UF/IFAS Florida-Friendly Landscaping principle on reducing stormwater runoff lists what catches or absorbs it: rain gardens, swales and berms catch and filter runoff, porous patios and walkways let water soak in, and downspouts can be pointed into planted areas. When you check the yard, look at where each downspout empties and where water crosses paving on its way to the low spot.
Checklist
What the fix involves, what it costs and how to compare quotes
Regrading, drains and rain gardens
The fixes fall into three groups. One is raising a low spot with soil, or leveling the yard. Another is a drain; WSU says tile lines fall 1 to 3 inches per 100 feet. The third is a rain garden, swale or berm, as the UF/IFAS runoff guidance above describes. Ask any company how it will find where your water comes from before it quotes a fix.
National ranges from the guides named below:
| Item | National range |
|---|---|
| French drain, average | about $5,000 on average; from $500 for minimal work up to $18,000 |
| French drain in the yard | $20 to $40 per linear foot |
| Curtain drain | $1,000 to $5,000 on average |
| Dry well, gravel or plastic tank | $50 to $700 (concrete up to $3,000) |
| Backyard drainage system | about $4,340 on average, up to $18,000 for major problems |
| Leveling a yard | $1,006 to $3,237, national average $2,122 |
| Leveling a 5,000 to 10,000 sq ft yard | $1 to $2 per square foot |
| Topsoil, per cubic yard | $12 to $55 (fill dirt $5 to $15) |
| Drainage installation labor | $50 to $100 an hour |
The French drain, curtain drain, dry well and labor figures come from Bob Vila's 2024 French drain guide. The backyard drainage average comes from its 2023 pavers-versus-concrete guide, and the leveling and soil figures from its 2023 yard leveling guide.
What moves the price: the length of the drain, because drains are priced per linear foot, and the hours of labor. Regrading adds its own line. Bob Vila's 2023 landscape design guide puts regrading or leveling at $1,000 to $3,000 extra nationally for labor and equipment when a yard needs it. For the wider picture, see our cost guide for Tampa landscape work, and see our landscaping page for how drainage fits into a full yard project.
Timeline, warranty and permits
Ask for a written start date and finish date with the quote. Bob Vila says a contractor will likely warranty French drain work for about a year; that is a general norm, not a rule, so get the warranty in writing, with what it covers and for how long.
Inside Tampa city limits, the City of Tampa Construction Services Division issues building permits through its Accela Citizen Access portal. Addresses in unincorporated Hillsborough County go to the county instead. Tampa Landscaping Pros pulls the City permit when the job needs one.
How to compare quotes for a drainage fix
The Better Business Bureau says a company that quotes without seeing the yard cannot know what it needs, so get a price after an on-site look. The BBB and the Federal Trade Commission agree on comparing bids for the same work and asking for an explanation when the estimates differ a lot. The FTC says a written estimate should list the work, the materials, the completion date and the price.
Ask for a certificate of insurance sent from the business's insurance agent. Do not pay the full amount up front, and do not make the final payment until the work is done and you are satisfied. In Florida, a residential contract over $2,500 must carry a lien warning: unpaid subcontractors or suppliers can claim against your property even if you paid the contractor in full, so ask for a written release of lien.
Questions about standing water in a yard
How long should water stand in a yard after rain?
WSU says that if surface water has not drained 2 or 3 hours after rain or watering, the yard has a drainage problem. Time it after the next storm.
Why is my Tampa yard soggy after every rain?
UF/IFAS describes flatwoods soils with a water table that can rise to within 5 to 20 inches of the surface, and UF/IFAS Hillsborough County says urban development here often leaves compacted soil. Neither is a survey of your lot. Check the grade, the downspouts and the weeds in the wet spot too.
Can a rain garden fix a soggy backyard?
UF/IFAS says rain gardens, swales and berms catch and filter runoff. Ask a crew whether one suits the spot where your water collects.
What does it cost to fix a yard that won't drain?
Nationally, a French drain averages about $5,000 (Bob Vila, 2024), and a backyard drainage system averages about $4,340 and can reach $18,000 for major problems (Bob Vila, 2023). Ask for a written, itemized price after the crew walks your Tampa yard and measures it.
Do I need to call 811 before a drain goes in?
Yes. Florida law requires a call to Sunshine 811 at least 2 full business days before digging.
Can my sprinklers cause puddles in the lawn?
They can: UF/IFAS says sedges, doveweed, dollarweed and eclipta in a soggy spot may signal a sprinkler leak. Tampa allows lawn watering only once a week, on your set day. If puddles appear without rain, have the sprinkler system checked along with the grade.
