Peoria, IL Environmental Rules: Erosion Control (2026)

Under Sec. 5-51, anyone building a new single- or two-family dwelling must first obtain a general erosion and sediment control permit, filed as a standard plan ($100 fee) or a site-specific plan ($150 fee); commercial, institutional, or multi-family projects disturbing more than 5,000 square feet need the fuller erosion, sediment and stormwater control permit under Sec. 5-76, with an application fee of $50 per acre (minimum $250, maximum $2,000). Sec. 5-29(a) requires all control measures to conform to the Illinois Urban Manual and the city's own erosion and sediment control criteria, and to be sufficient to prevent sediment from leaving the site during a 20 percent frequency storm event; if sediment does escape, the owner, developer, or contractor must remove it within four hours or by the end of the work day.

Sec. 5-30 requires sediment control measures to be built and functional before any clearing, grading, stripping, excavating, or filling starts, and to remain in place until the ground is permanently stabilized, with permanent cover established within three days of removing sediment barriers. Developers of subdivisions must post surety for 100 percent of the cost of permanent erosion control measures under Sec. 5-79, and no certificate of occupancy issues until those measures are installed and approved. The erosion control administrator, appointed by the city manager, enforces the chapter through periodic inspections and can revoke a permit outright if standards are being violated.
