Standing Water in the Yard: Finding the Actual Cause

Water standing in a Florida yard after rain is common, and the right fix depends entirely on why it is standing.

The four common causes

1. Grade

The ground slopes toward the problem area, or does not slope away from it. This is the most common cause and frequently the cheapest fix.

Check: watch where water actually runs during rain, and look at where the property is low relative to its surroundings.

2. Compaction

Water cannot infiltrate because there is no pore space in the soil. Extremely common on new construction, and the water sits on the surface rather than soaking away.

Check: screwdriver test. If it stops within an inch or two, the soil is compacted.

3. A high water table

In low-lying parts of Central Florida the water table rises during the wet season, and once the ground is saturated from below there is nowhere for surface water to go.

Check: if the whole area is soggy for days after rain and neighbouring properties are similar, this is likely part of it. It is also the hardest to change.

4. Concentrated discharge

Downspouts, gutter outlets and A/C condensate lines all discharging in the same place. Roof water is a large volume concentrated into a small area, and a downspout emptying beside a foundation is both a drainage problem and a foundation problem.

Check: walk the property during rain and look at where every downspout goes.

The fixes, matched to the cause

• Regrading for a grade problem — establishing fall away from the house and toward somewhere water can go. Cheapest and most durable where it applies.
• Aeration and soil improvement for compaction, which improves infiltration.
• Downspout extensions to carry roof water well away, which is frequently the single easiest fix on the list.
• A French drain to collect and move subsurface water, where there is somewhere legal and sensible to take it.
• A dry well to hold and infiltrate water where there is nowhere to discharge to.
• A rain garden or bog planting where the area cannot realistically be drained — turning the wet spot into a designed feature rather than a failure.

Where the water goes matters legally

You cannot simply move water onto a neighbouring property. Any drainage design has to discharge somewhere it is permitted to go, and in some jurisdictions that means a permit. It is worth establishing before work starts rather than after a complaint.
