Drainage Engineer in Anderson, TX
Drainage is the Anderson issue that shows up as a neighbor dispute, a failed inspection, or a flooded slab. ALFA Engineering designs grading and drainage so stormwater leaves your site the way the rules require. Anderson's proximity to the Navasota River requires careful drainage design for site development. Those conditions are the design's starting point, not a footnote. The finished design gives Anderson owners a site that works in the weather, not just on paper.

Drainage and floodplain questions get answered from your parcel's actual conditions, not guesswork.
Send the property address, construction scope, available plans, photos, permit comments, and whether work is proposed, underway, or completed.
What Anderson property owners are deciding
A Anderson permit review just returned a drainage comment nobody on the project expected. Unmanaged runoff does not negotiate; it finds the lowest opening and bills you later. What your site needs depends on its soils, contours, impervious cover, and City of Anderson Planning Department's drainage criteria.
