Drainage Engineer in Columbus, TX
Grading looks like dirt work until the first hard rain rewrites the plan in Columbus. The drainage package covers grading, routing, calculations, and the documentation reviewers require. Columbus's proximity to the Colorado River requires careful drainage design for development. Those conditions are the design's starting point, not a footnote. The finished design gives Columbus owners a site that works in the weather, not just on paper.

What Columbus property owners are deciding
The Columbus project is designed, but nobody has shown where the water goes. Every drainage shortcut resurfaces as a review comment, a repair, or a lawsuit. What your site needs depends on its soils, contours, impervious cover, and City of Columbus Planning Department's drainage criteria.
