Broken Arrow, OK Environmental Rules: Erosion Control (2026)

The City of Broken Arrow requires anyone excavating, grading, regrading, landfilling, berming, or diking land within city limits to first obtain an earth change permit from the city manager under Broken Arrow Code § 13-19. The permit can carry conditions such as a drainage plan, finish-grade drawings, retaining walls, detention facilities, and erosion controls, and must be renewed if a project isn't substantially underway within one year. Small projects, under 12 inches of cut or fill, tracts under three acres, or bona fide farming operations meeting the zoning code, are exempt under § 13-23, unless the land is in the regulatory floodplain or drains more than 40 acres.
