This should've been done as the foundation of the house was being built. The ground needs to slope away from your house so that it provides as a water runoff away from your house. From a level base, a 10 to 20 degree slope is what you need to have the ground slope away from your house. This slope should be at a minimum distance of 1 meter to a max of 3 meters. The countour of the rest of your lawn shouldn't matter past this point.
Good drainage is vital to having a dry house. A solid foundation with the drainage system and a waterproof membrane are critical. The ground around the house needs to slope away from the foundation. A good roof also protects the house, as do the siding materials.
I usually like 12" from dirt to the 1st wood Code requires AT the building a min of 6" If you will be adding mulch then you need to allow more clearance The ground must then slope away from the house for 10' The slope must be around a 5% slope
Slope dirt downward and away from foundation, extend downspouts and keep gutters clean, and in severe cases, install drainage ditches.
Ideally, you would start a foundation 12" out of the ground at the grounds highest point. Remember to check for drops and slopes such as porches, garages. Exceptions can be made for situations where the ground is sloped as long as the slope will take water away from the slab.
A pithouse (pit house) uses natural land features, such as a depression of ground in front of a bank or slope of land, to build a protective enclosure for people or animals. The slope of land forms one "side" of the house and is a natural wind break. Poles set at four corners in front of the slope can then be blocked (such as fencing) or covered (roof and walls). During warm weather, the slope provides coolness from exposed ground at the back of the pit house. Leaves, branches, and mud form semi-sturdy walls and roof.
you dont
The slope of the land makes the water go downhill faster, giving it less time to saturate into the ground, so less will get into the ground
An inclined plane is basically a slope. So just find somewhere in your city where the ground slopes.

Ground that has a natural incline, as the side of a hill.
