Yard Drainage Solutions in Shreveport, LA

The Diagnosis Comes First

A good drainage estimate in Shreveport starts with a walkover during or right after a rain event. The contractor looks for: (1) where runoff enters the property, (2) where it collects, (3) where the natural low points and existing swales are, (4) how the roof discharge integrates or fights the yard grading, and (5) what the soil profile looks like — a small pit or a soil probe tells the crew whether the topsoil is 6 inches of loam over 3 feet of gumbo clay or something more workable. In North Shreveport and along the Red River bluffs the profile is very different from the flat, clay-dominated lots in southeast Bossier.

Six Fixes We Actually Deploy

1. Downspout extensions and buried discharge lines — cheapest fix in the toolkit, solves a shocking percentage of soggy-corner problems. 2. Regrading and swale cuts — moving 6-12 inches of soil to give water a defined path. Often paired with sod re-lay. 3. Surface drains (catch basins + solid PVC) — for a low pocket that catches runoff from an impervious surface. 4. French drains — for subsurface saturation and hillside seepage; see the French drain page. 5. Dry wells and infiltration basins — where you have nowhere to daylight and the soil below the clay layer takes water. 6. Sump pumps — mechanical answer when gravity really has run out; see sump pump installation.

Which Fix Belongs on Which Yard

A soggy strip 3 feet out from the foundation on the northwest side of a Broadmoor house is usually a downspout-extension job — the gutters are dumping 20 feet of roof at a corner and no French drain is going to keep up. A whole-yard bathtub in a flat South Highland lot is almost always a regrading and swale job, sometimes with a light French drain on the property line. A wet crawlspace under an East Ridge or Southern Hills 1950s ranch is a curtain-drain-and-sump problem. A hillside seep in Ellerbe Woods or above Long Lake Estates is textbook French drain. Getting the diagnosis wrong is how you spend $8,000 and still have standing water.

Clay Soils and Percolation Rates

Percolation in NW Louisiana clay is typically under 1 inch per hour, and often close to zero once the soil is saturated. That's why dry wells sized by rule-of-thumb often fail here — a chamber sized for sandy percolation floods out within a season. A quick percolation test (dig a 12-inch hole, saturate overnight, then measure drop-per-hour) gives you a real number to size dry wells and infiltration basins around. Any contractor unwilling to do or defer to a perc test on a dry-well job in Caddo Parish is guessing.

Downspout Discharge — The Cheapest Big Win

A single 6-inch downspout dumps roughly 1 gallon of water per minute per 100 square feet of connected roof at a moderate rainfall rate. Multiply by 4-6 downspouts, times a 1-inch-per-hour Shreveport rain, and you're moving thousands of gallons off the roof in an hour — all of it currently going into a 4-inch splash block. Extending each downspout with a 4-inch solid PVC line out at least 8-10 feet — or all the way to a rain garden, dry well, or property-line daylight — is often the highest-leverage first pass before spending on trench work. Buried is better than surface for lawn mowing and aesthetics. See downspout drainage.

Regrading When the Yard Slopes Wrong

IRC and most builder specs call for at least 6 inches of drop in the first 10 feet away from the foundation. A lot of older Shreveport homes never had that, and many that did have settled backward over the decades. Correcting negative grade around the foundation is the single most important thing you can do for a wet crawlspace, seepage in a slab, or brick-mold rot. The work is often quiet — a bobcat pushing 4-6 inches of topsoil, a light sod re-lay, sometimes a swale cut down-slope — but it changes the water balance around the house for the next 40 years. See grading and regrading.

What the Callback Includes

When you request a callback, a coordinator schedules a walkover — typically during or just after a rain if possible, or a hose-test if the weather isn't cooperating. The contractor sketches a proposed system, marks approximate trench lines and discharge points, calls LA811 for utility locates before any digging is scheduled, and gives you an itemized written quote. No high-pressure sales visits, no 'sign today for a discount' tactics.
