Common exterior drainage problems
Wet lawns and recurring puddles may result from slope, roof discharge, compacted soil or a blocked drainage path.
Surface drains collect visible water. French drains intercept water in saturated soil. Grading and downspout routing solve different parts of the problem.
What to check before planning drainage work
- Observe the yard during rain
- Check low areas near patios and fences
- Confirm where collected water can leave the property
Check subdivision drainage paths before changing grade
The City of Simpsonville storm-water policy says the city maintains storm drainage within city street rights-of-way, while private-property drainage is generally the property owner’s responsibility.
A shallow swale may be serving several lots even when it looks like part of the lawn. Before filling a low strip or cutting a trench through it, confirm whether it is part of the intended drainage pattern or an HOA/shared drainage feature.
Confirm where the water can go
Any proposed drain needs a lawful and suitable outlet. Do not assume water may be directed onto neighboring land or into public infrastructure.
Confirm utility locations, drainage easements, permits and other local requirements before excavation.
