Solving a Soggy, Muddy Lawn with Proper Drainage

A lawn that stays wet for days after rain, with water cracking the driveway, signals a serious drainage issue. In Lanham, MD (Zone 7a), clay soils, low elevation, and runoff from neighboring yards compound the problem. An old above-ground pool site may have compacted the soil further.

Why It's Urgent

• Standing water kills grass roots and invites moss, algae, and disease.
• Water under the driveway causes cracking and structural damage.
• Foundation risk increases if water pools near the house.

Recommended Solution: French Drain & Dry Well

1. Install perforated drainage tile (French drain) in a trench sloped 1–2 inches per 10 feet.
2. Line trench with landscape fabric, add 6–8 inches of coarse stone, lay pipe, cover with more stone, wrap fabric, then backfill.
3. If no legal outlet exists, build a dry well: 3×3×3 ft hole lined with fabric, filled with large stone, wrapped, and covered with 12+ inches of soil.
4. Route downspouts and surface runoff into the system.

When to Call a Pro

For complex grading, high water tables, or suspected springs, hire a landscaper or drainage contractor. DIY is possible for simple cases, but mistakes worsen the problem.
