Dry ground and hard rain need a planned route for runoff.
Round Rock often gets fast, heavy rain after a dry stretch. When clay is dry or compacted, it sheds water rather than letting it soak in quickly. Shallow swales and small collection points can fill faster than they can carry runoff away, leaving water to spread across the yard or collect beside the house.
Variable clay and limestone ground also limit how much a drainage plan can rely on infiltration alone. We start with the surface grade and the path water actually takes during a storm. That shows whether the problem calls for reshaping the flow of water, collecting it at a low point, or using inlets and solid pipe to move water from a defined problem area.
Moving water is only part of the job. A discharge route needs enough fall to keep flowing and an outlet that does not send runoff against a slab, along a fence line, or into another low area. Protecting the outlet also helps keep sediment, rock, and storm debris from repeatedly blocking the system.
