Checking that you have the proper drainage for your yard is more than simply checking that the downspouts aren't clogged. Proper sloping away from your home ensures that you don't have a soggy basement or standing water issues. To determine if you have proper drainage, check the slope from your foundation. Healthy drainage occurs when the slope is between 2 percent and 5 percent, which equates to 2 to 5 inches of drop-off for every 10 feet you measure as you move away from your home.
1. Pound the first garden stake into the ground immediately adjacent to your foundation.
2. Measure off 10 feet of string from the first stake walking directly away from the house.
3. Pound the second garden stake into the ground at the 10-foot distance.
4. Attach the string to the first stake and then the second stake.
5. Attach the string level to the string and adjust the string and stakes until the string level shows that the string is horizontal.
6. Measure the distance between the ground and the string on the first stake. Measure the distance between the ground and the string on the second stake.
7. Subtract the measurement of the first stake from the measurement of the second stake. Divide this number by 120, the number of inches in 10 feet. Then multiply by 100 to determine the percentage of the slope. If the percentage is less than 2 percent, you will need to regrade your yard to obtain the proper slope.
