Top 7 Yard Drainage Mistakes (And How to Avoid Them)

Bad drainage can silently destroy your lawn, damage your home’s foundation, and turn your landscaping into a soggy mess. Worse? Many homeowners try to fix drainage problems and unintentionally make things worse.

Here are the 7 most common yard drainage mistakes—and what you should do instead.


❌ Mistake #1: Letting Downspouts Drain Near the Foundation

Why it’s a problem:
When gutters dump water within a few feet of your house, it can saturate the soil, seep into the basement, or cause foundation cracking.

The fix:
Use 10+ foot downspout extenders or buried drainage pipes with a pop-up emitter to move water away from the structure.

❌ Mistake #2: Ignoring Poor Grading

Why it’s a problem:
Your yard should slope away from your house. A flat or reverse slope can cause pooling near your foundation or low spots in your yard.

The fix:
Regrade problem areas to ensure a slope of at least 1 inch per foot for the first 5–10 feet from your home.


❌ Mistake #3: Using Only Surface Solutions for Deep Problems

Why it’s a problem:
Splash blocks or extenders are fine for minor runoff, but they won’t fix deep pooling or water that doesn’t absorb into the soil.

The fix:
Use subsurface solutions like French drains or dry wells for areas where water consistently collects and doesn’t drain naturally.


❌ Mistake #4: Choosing the Wrong Drain Type

Why it’s a problem:
A trench drain is great for driveways, but useless in soggy lawns. A French drain handles soil saturation but won’t help with patio runoff.

The fix:
Match the drain type to your specific issue:

  • French drains = subsurface water
  • Trench drains = surface runoff
  • Catch basins = localized pooling

❌ Mistake #5: Not Accounting for Clay or Compacted Soil

Why it’s a problem:
Clay-heavy or compacted soils don’t drain well. Even with proper grading, water may pool on the surface instead of soaking in.

The fix:
Aerate the soil, amend it with compost or sand, and consider installing drainage features like dry wells or French drains.

❌ Mistake #6: Blocking Natural Drainage Paths

Why it’s a problem:
Fences, garden beds, retaining walls, and even mulch can block water from flowing where it naturally wants to go, leading to backups and ponding.

The fix:
Plan landscaping with water flow in mind. Use open-bottom edging, cut drain gaps in hardscaping, or install catch basins to redirect water.


❌ Mistake #7: Skipping Maintenance

Why it’s a problem:
Even well-installed drainage systems can fail if they’re clogged with debris, leaves, or sediment.

The fix:

  • Clean out gutters and downspouts regularly
  • Inspect French drain or trench grates after storms
  • Flush underground pipes annually if possible
