Your best bet may be to install underground pvc piping to manage water runoff.
Best way to run gutters away from house.
My plan was to use 4 pvc pipe with fittings to make a y shape away from the house.
Attach elbow to bottom end of downspout and connect a downspout extension to carry rainwater away from the foundation.
They should direct water at least 6 feet 1 8 m away from the foundation of your house.
The drainage pipe used for extending downspouts is non perforated schedule 40 pvc pipe with 4 inches diameter.
On the flip side burying drain pipe is more work intensive but it s a guaranteed way to keep water away.
The most difficult part is digging the trench.
We suggest topping the pipe off with a pop up emitter.
Water flows downhill so you have to have some amount of slope so the water will run somewhere.

Besides making sure the slope is correct you ll want to make sure the pipe run ends in a good location.
Downspouts are the parts of the gutter that run vertically from the roof gutter to the ground.
While the house sits on flat ground there is enough slope in the back yard for this project to work.
