Full Breakdown
Laredo Engineering Department issues grading permits under Chapter 31 and the Land Development Code. Grading over 50 cubic yards of cut or fill, or any excavation over 3 feet deep, requires an engineered grading plan stamped by a Texas licensed professional engineer. Plans must show existing and proposed contours, drainage patterns, retaining wall locations, and erosion controls. The engineer must certify no adverse impact on upstream or downstream neighbors: diverting runoff onto adjacent property is a civil tort and code violation. New residential construction requires positive drainage: grade falls minimum 6 inches in the first 10 feet from foundations (IRC R401.3). Lots with slopes over 15 percent require geotechnical review. Retaining walls over 4 feet tall (measured from bottom of footing to top of wall) require engineered plans and building permits.
Violations & Fines
Unpermitted grading: stop work, 500-2,500 dollars. Runoff onto neighbor: civil liability plus abatement order. Wall over 4 feet unpermitted: tear-down risk.
