Why Some Yards Flood After Heavy Rain
Standing water in a yard after rain is usually a sign that the ground cannot drain water fast enough or that the property grading directs water toward a low point. In the Fraser Valley, frequent rainfall and clay-heavy soil can make drainage problems more noticeable, especially on flat or poorly graded lots.
Flooding does not always require major reconstruction, but it does require identifying where the water is coming from and where it should be directed.
Common Causes of Yard Flooding
The most common issue is improper grading. If the ground slopes toward a structure or dips in the middle of a lawn, water naturally collects in those areas. Compacted clay soil can also prevent water from soaking into the ground.
Another frequent cause is runoff from nearby roofs, driveways, or neighbouring properties. During heavy rainfall, these surfaces move large amounts of water into the yard.
When Drainage Systems Are Needed
Some drainage problems can be solved by adjusting surface grading so water flows away from the problem area. In other cases, underground drainage such as trench drains or French drains may be required.

Addressing the Problem Early
Water that sits on the surface can lead to lawn damage, soil erosion, and moisture problems near foundations. Identifying the drainage path early prevents more costly issues later.
