Cumberland County averages over 55 inches of rain per year, and the clay-heavy soils across the Plateau don't drain freely. If you're dealing with standing water, soggy areas, or erosion on your property, you're not dealing with bad luck — you're dealing with a drainage problem that has a solution.
Diagnose the Problem First
Not all standing water has the same cause. Water pooling near the foundation usually means the grade is sloping toward the house. Soggy areas in the middle of the yard typically indicate a high water table, subsurface clay layer, or low spot accumulating surface runoff. Erosion on a slope means runoff velocity is too high and needs to be slowed and directed.
French Drains
The most versatile drainage solution — a perforated pipe in a gravel trench that intercepts water moving through the soil and carries it to a discharge point. French drains work well for foundation moisture, soggy yard areas, and managing water behind retaining walls. Cost in Cumberland County: $25–$60 per linear foot installed depending on depth and soil conditions.
Channel & Trench Drains
Linear surface drains that catch sheet flow at a specific location — across a driveway, at the edge of a patio, or at the bottom of a slope. The water enters through a grate and is piped away. Best used when you need to intercept a large volume of surface water at a precise point.
Downspout Extensions & Underground Routing
Downspouts dumping water directly against your foundation are one of the most common and easiest-to-fix drainage problems. We route downspouts underground in rigid pipe to a daylight discharge point 10–15 feet away from the structure. Cost: $300–$800 per line.
Dry Creek Beds
A dry creek bed is both functional and decorative — it channels water during rain events through a stone-lined swale while looking like a natural landscape feature the rest of the time. Works well on sloped lots where you want to control where water flows without hard infrastructure.
Regrading
Sometimes the fix is simply re-establishing proper slope. If your yard is graded toward the house or has accumulated low spots over time, regrading with a skid steer and box blade may be the most cost-effective solution before adding any pipe system.
