Water needs a complete route away from the house.
In Manor, low-relief lots do not always give rainwater a natural direction away from the house. During intense rainfall, water can collect around downspouts, across flat side yards, and in low spots that have settled beside patios or foundations. Clay-rich ground is especially slow to take in more water once it is already saturated, leaving runoff on the surface instead of letting it soak away.
A useful drainage system handles the whole route, not just the spot where water first appears. We look at where runoff is collected, how a drainage pipe is pitched, where it discharges, and whether that outlet stays open when rain is heaviest. A catch basin without a clear destination simply moves the collection point and can leave standing water behind.
Keeping surface water away from the foundation matters when the soil repeatedly becomes wet and then dries out. Changes in moisture make clay soil change volume, and repeated cycles beside the building contribute to uneven movement in the ground. Drainage planning focuses on directing that water away rather than allowing it to remain against the house.
