Drainage Assessment in Tulsa, OK

Before recommending any solution, a local contractor walks your property and assesses the actual drainage situation — where water is collecting, what the soil and grading conditions are, and what's causing the problem. You get a clear picture of the issue and honest options for addressing it — no charge for the assessment.

Tulsa sits along the Arkansas River on rolling terrain that's hillier than most of the state, with soil that shifts from river-bottom clay near downtown to shaley, rockier ground on the surrounding hills. That hillside grading means water moves fast off upper lots and concentrates in low points — the older neighborhoods of Brookside, Maple Ridge, and Swan Lake, built from the 1920s through the 1950s, were laid out before modern storm-sewer capacity was standard, and their combination of mature tree cover and aging drainage infrastructure means heavy rain backs up quickly. Tulsa's proximity to the river also means a higher water table in low-lying areas near the floodplain. Green Country's humid subtropical climate brings frequent heavy thunderstorm cells off the Gulf, and the hill-to-hollow terrain around Tulsa concentrates that runoff into specific yards and basements rather than spreading it evenly the way flatter Oklahoma City does.

What Gets Checked During a Drainage Assessment

A contractor checks the grade around your foundation, the slope of the yard toward or away from the house, downspout placement and outlet conditions, soil compaction and permeability, existing drainage features that may be failing or undersized, and low points where water naturally concentrates. In Tulsa County, clay-heavy soils often make drainage problems worse — that's factored into the evaluation.

What You Get After the Assessment

After walking the property, the contractor explains what was found in plain terms and gives an honest recommendation. If a simple fix like regrading or extending a downspout will solve the problem, that's what you'll hear. If a more involved drainage system is needed, you'll get an explanation of why, what it includes, and what it costs. There is no pressure to hire anyone after the assessment.
