What a yard drainage plan looks at
A real drainage plan starts at the roof and follows the water all the way to an outlet. It maps where downspouts dump, how water sheets across the yard, which spots collect and hold water, and where the slope is running back toward the house. On most Athens lots that means combining several tools: french drains under the low spots, catch basins at downspouts and patios, extensions that carry roof water out to the lawn, and small regrades where the ground has settled toward the slab.
Why full-yard planning matters on Henderson County lots
Henderson County sits on sandy loam over dense clay subsoil. That clay swells shut when wet, so nothing soaks in during heavy rain. Water sits, moves along the surface, and pools at the lowest point it can reach. Fixing one wet area without planning the whole lot usually just pushes the water to the next low spot. In older Athens subdivisions and newer builds along the I-35E corridor, this shows up as a fence line that grows moss, a bed of dead shrubs, a patio that stays wet a day after every rain, or worse, water stains creeping up the foundation.
Common pieces of a Athens yard drainage system
- French drains under the wettest low areas and along the back of the yard.
- Catch basins at downspouts, patios, and any spot where surface water collects.
- Downspout extensions that carry roof water 10 to 20 feet away from the slab.
- Channel drains across driveways and pool decks that would otherwise sheet water back at the house.
- Regrading in small areas where the ground has settled and now slopes toward the foundation.
- One or two outlets that daylight to a lower part of the yard, a curb cut, or a swale.
Step by step: how a full yard drainage project runs
- Site walk. A licensed local pro walks the lot, ideally after a rain, and notes every wet area, every downspout, and the elevations that matter.
- Design and quote. The plan lays out trench lengths, catch basin locations, pipe sizes, outlet, and any regrading, with a written price.
- Utility locates. Called in before any trenching in Henderson County.
- Trenching and pipe. French drain trenches are cut, lined, filled with gravel, and piped to the outlet.
- Basins and tie-ins. Catch basins and downspout extensions tie into the main drain line.
- Regrading and restoration. Small regrades, fresh soil, sod, or river rock finish the job.
- Test. Crew runs water at every basin and downspout to confirm flow.
How long does it take?
Most full-yard drainage projects run two to five days once the crew is on site. Larger lots, multiple long trench runs, and jobs that include regrading can push a week. sandy loam over clay subsoil slows every step, and heavy rain during the job usually pauses trenching for a day.
What to have ready when you call
- How many wet spots and where they are on the lot.
- Whether water reaches the foundation, patio, or garage.
- Where your downspouts are and where they dump.
- Whether the yard slopes to daylight or is basically flat.
