Table 4. Nominal and Actual Dimensions of Lumber and Maximum Rise for Con-
struction of Level Raised Beds.
To negotiate the 32 inch slope over a 14 foot span. 2x12 lumber is 11ΒΌ inches wide (high),
so 3 steps at 11.25 inches = 33.75 inches, so 3 steps would work using the 2x12 lumber. If
the slope had been over 33.75 inches, I would have had to add a step, shorten each bed or
keep three steps but have to shorten the span.
