Dry ground sheds the first hard rain, then saturated clay holds water in place.
Clyde’s long dry stretches leave ground hard at the surface. When a short, heavy storm arrives, water runs across that hard ground instead of soaking in gradually. Once clay-rich soil takes on enough water, it drains slowly, so runoff can remain at the low points of a yard after the rain has ended.
That pattern makes the route of water more important than the presence of a drain alone. Water often gathers along slab edges, beneath downspout outlets, and beside paving or other hard surfaces that turn runoff toward the building. A catch basin placed in a low spot still needs a workable outlet; without one, it only collects water where it already wants to stay.
We start with the actual slope of the lot and the points where stormwater enters it. A shallow swale, a downspout extension that carries water away from the foundation, or a correctly sloped collection line each has a different job. The aim is to direct water away from the house without sending it toward another structure, washing out paving, or keeping the ground around buried plumbing and the foundation wet storm after storm.
