D Dexman PE Mar 9, 2010 #2 CERM (10th edition) Chapter 82: Construction & Jobsite Safety. Part 2. Trenching & Excavation. It explains there are 3 soil classifications for trenching A, B, & C with C being the most unstable. Type A: .75/1 (H:V) max slope Type B: 1:1 Type C: 1.5/1 In Colorado, the standard practice is to assume ALL soils are Type C unless proven otherwise. Last edited: Mar 9, 2010
