Drainage & Culverts

Surface drainage comes first

Before anyone sells you pipe, the surface needs to be right. Water has to have a continuous path downhill to an outlet. On ground this flat, that path often has to be cut — a shallow swale or a graded ditch with consistent fall. It does not take much fall, but it has to be continuous. One flat section or one high spot and the whole run backs up. This is unglamorous work and it solves more problems than any buried system.

Where the water is going to go

This is the question that determines whether a drainage job is possible. Every system needs a legal outlet: a roadside ditch, a county drainage ditch, a creek, or a pond on your own property. You cannot simply discharge onto a neighbor's land, and doing so creates liability. In many parts of Chambers and Jefferson County the outlet is a drainage district ditch, and connecting to it may require coordination with that district. We identify the outlet before designing anything.

Culverts, sizing, and the cost of getting it wrong

A culvert that is too small will not pass a heavy rain, so water backs up behind it and goes over the top — usually taking your driveway with it. Culverts also silt in and need occasional cleaning. Where a culvert crosses under a county road approach, the county typically specifies the size and requires a permit. Where it is entirely on your property, sizing is our call and we would rather go a size up than have you rebuild it.

French drains and subsurface work

A French drain — perforated pipe in a gravel trench, wrapped in fabric — handles subsurface water and is useful around foundations and in specific wet spots. On heavy clay it has real limits: clay does not deliver water to the pipe quickly, so a French drain in gumbo will underperform what people expect from it. We use them where they are appropriate and we will tell you when surface grading would serve you better for less money.
