Drainage Engineer in Dayton, TX
Grading looks like dirt work until the first hard rain rewrites the plan in Dayton. ALFA Engineering designs grading and drainage so stormwater leaves your site the way the rules require. Dayton's Liberty County soils include expansive clays and alluvial deposits requiring specialized foundation design. Soil behavior determines how the site absorbs, sheds, and routes stormwater. The finished design gives Dayton owners a site that works in the weather, not just on paper.
