# Duluth UDC § 1011.05

Soil Stabilization

**Governing jurisdiction: Duluth.** A "Duluth, GA" mailing address is usually NOT in the City of Duluth. Unincorporated Gwinnett is 67.3% of the county's land area and is governed by a different code, a different board and a different permit portal. Resolve the governing jurisdiction before answering any zoning question.

## Text

While most soils in the area can be safely stabilized at a 2:1 slope, some soils exhibit a low shearing resistance and
a low cohesiveness. These soils typically are micaceous silts and sandy soils with little or no clay. If the 2:1 slope
shows evidence of shearing, non-cohesiveness, sliding, or inability to maintain compaction, the slope shall be
stabilized at 3:1 or by using such mechanical methods as needed (such as retaining walls or "grow mats" stapled in
place) to maintain slope, height, and integrity.
