One Inch Per Foot Slope
The best way to explain
a 1 inch per foot slope would be to examine the picture above. The brown
polygon or four sided object is 12 inches wide. At one end we have 6
inches and on the other end we have 7 inches.
For every 12 inches of horizontal distance (right to left), it will drop
1 inch in vertical distance (up and down).
Example: If I had a 10 foot sidewalk with a 1:12 slope, it would drop 10
inches in 10 feet. If I had a 15 foot driveway, it would slope 15 inches
to maintain the same slope.
Slopes like these provide good drainage during rainstorms and prevent
water from ponding up and becoming a problem.
