How to Read a Yard Drainage Estimate

Read a drainage estimate in construction order: investigation, access, excavation, materials, outlet, restoration, and follow-up.

A total is easier to judge when you can picture what happens on the property from arrival through the first rain after completion. Use this line-by-line reading order to find vague or missing parts of the scope.

Problem statement

Look for the location and observed symptom the estimate is addressing. A clear scope should avoid promising a universal result when elevations or concealed conditions still need verification.

Access and protection

Confirm the equipment route, surfaces that need protection, staging, utility coordination, and how the crew reaches the beginning and end of the drainage path.

Excavation and materials

The estimate should describe the work areas and the relevant pipe, stone, inlet, soil, or grading components without relying on a product name to explain the entire solution.

Outlet and finish grade

Find the intended destination and the elevations or surface transitions that make the route work. Ask for clarification if the scope collects water but does not explain where it goes.

Restoration and follow-up

Identify backfill, settlement expectations, lawn or bed restoration, cleanup, maintenance access, and what to observe during early rain events.
