Wylie, TX Environmental Rules: Erosion Control (2026)

Wylie's erosion and siltation control article, Chapter 42 Article IV, opens with the property owner's baseline duty in Sec. 42-71: control erosion and siltation of soil materials on the owner's own property and stop water runoff from carrying silt, earth or topsoil onto others' properties or into city streets, alleys, drainage easements, drainage facilities or storm drains. The section makes the owner liable for damages caused by builders, contractors or developers performing construction on the property that creates or worsens erosion, so a homeowner cannot point to a contractor to escape responsibility.

Sec. 42-72 layers on a contractor-specific duty, requiring construction plans and specifications to address erosion and siltation control measures and requiring the site be left in a stabilized condition at completion, with the city free to deny approval of plans it finds inadequate. Sec. 42-73 backs the article with a permitting lever: the city can withhold plat, drainage, building permit or certificate-of-occupancy approval if adequate erosion controls are not in place or if the property is a major contributing cause of off-site sedimentation. This dovetails with the grading-permit article, Sec.

42-92 through 42-98, which requires a grading permit and, for sites disturbing five acres or more, an erosion control plan approved by the city engineer plus a TCEQ stormwater permit under Sec. 42-95. Sec. 42-74 sets the penalty for any Article IV violation at the general penalty in Sec. 1-13.
