Checking that you have the proper drainage for your own lawn is more than simply checking that the downspouts aren’t clogged. Good sloping away from your house guarantees that you don’t have a sloping basement or standing water difficulties. To determine if you have proper drainage, check the slope from your base. Wholesome 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 house.
Pound the first garden stake into the ground immediately adjacent to a base.
Step off 10 feet of string from the first stake walking directly from your house.
Pound the second garden stake into the ground in the 10-foot distance.
Attach the string to the first stake and then the next stake.
Attach the string amount to the string and adjust the string and stakes until the string amount shows that the string is horizontal.
Assess the distance between the ground and the string around the first stake. Assess the distance between the ground and the string around the next stake.
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, then you’ll need to regrade your lawn to acquire the proper slope.
