How steep is the average slide?
How steep is the average slide? The simple rules are that the overall angle from top to bottom must not exceed 40 degrees. 35 degrees is more normal, 40 is a little steep. A drop slide can be as steep as 60 degrees at the top, but will need a much longer run out at the bottom to make the overall average angle stay within the 40 degree guideline.
What slope is too steep?
Steep slopes are legally defined as hillsides having a 15 foot, or greater, vertical rise over 100 feet of horizontal run, or 15% slope (Figure 1). They are often undesirable ar- eas for development due to the difficulty of building on steep grades.
