Why Yard Drainage Comes Before Hardscape
Water that pools near a house can soak foundations, crawlspaces and new patios. Yard drainage should get fixed before pouring concrete or planting beds, because those projects lock in the grade. Most fixes involve sloping soil away from the house, extending downspouts and adding drains where water collects.
Watch the yard during a heavy rain to see where water actually goes.
Signs of Drainage Problems
Standing water after storms, damp crawlspaces, soil washing away and stains on foundation walls signal trouble. Also mold or musty smells in lower areas may point to water. So note every wet spot on a sketch.
Grading Away From the House
Soil should slope away from the foundation so water flows out. Over time, beds and paths can build up against walls. Then water runs toward the house instead.
Yard Drainage and Downspouts
Roof water concentrates at downspouts. Extending them away from the foundation or connecting them to drains spreads that water safely. Because a roof sheds large volumes, this step often helps most.
- Extend downspouts away from walls
- Regrade soil to slope outward
- Add surface or channel drains
- Keep gutters clean
Drains and Dry Wells
Surface drains collect water from low spots. Channel drains catch runoff across patios. Where allowed, dry wells let water soak in away from the house.
Patios and Slope
New patios need slope away from the house. The article on concrete versus pavers explains surface choices, including permeable pavers.
Yard Drainage and Foundations
Water drives many foundation problems. The article on foundation repair before remodeling explains warning signs.
Neighbors and Runoff
Redirecting water onto a neighbor’s lot can cause disputes. So plan outlets carefully and ask local officials about rules.
Permits
Rules differ by city. Rancho Cordova publishes a permit list that shows which projects need permits, so check grading or retaining walls against it. The City of Sacramento notes plan reviewers check site items during plan review for larger projects.
Yard Drainage Costs
Simple fixes such as downspout extensions cost little. However, regrading and drain systems cost more. So start with the simple steps and watch results.
Yard Drainage and Soil Types
For example, dig a small hole, fill it with water and watch how long it takes to drain. Then use the result to decide between surface drains and areas where water can soak in. Also remember that compacted soil from construction drains worse than undisturbed ground. So loosen compacted areas before planting.

Planning the Sequence
Fix drainage, then build patios and plant. Good yard drainage protects both the house and the new landscape.
