Why Triangle yards stay wet: clay, grade, and what actually works
Piedmont clay does not percolate like sand. Here is the order we use before anyone talks plants.
Wake County soil is heavy. After a storm, water sits in low corners, along the slab, and in the side yard that was never graded when the house was built. Homeowners often buy more mulch or more sod and the wet spot comes back.
The first question is where the water is allowed to go. Downspouts that dump next to the foundation, a patio that pitches toward the house, and a fence line that dams the lot are more common than a ‘bad French drain.’ We watch the yard after rain or run a hose, then pick the shortest path to daylight or an approved outlet.
Surface grade is cheaper than pipe. If we can tilt the lawn two percent away from the house, we do that before we trench. When pipe is needed, we use catch basins at the low spots and a solid or perforated run that can be maintained. Rock and fabric belong in the trench, not as a decorative pile that clogs.
Only after water has a path do we talk sod, beds, or hardscape. That order is how a Raleigh yard stays usable in July thunderstorms instead of turning into a repair loop.
