2 Slopes

Use the following guidelines for land selection:

1. Slopes under 1% do not drain well.

2. Slopes under 4% seem flat and are usable for all kinds of activity.

3. Slopes of 4 to 10% are easy grades.

4. Slopes over 10% are steep.

5. Slopes at 15% approach limit of an ordinary loaded vehicle.

6. Slopes at 25% are the limit of mowed surfaces.

7. Slopes over 50% may have erosion problems.

3 Site Selection

(For Temperate Climates)

Avoid or make special provision for steep north slopes; west slopes facing water; hilltops; frost pockets or positions at the foot of long, open slopes; bare, dry ground; nearby sources of noise or air pollution. Best sites are well-planted middle slopes facing south, near water.
