The barn had some initial drainage problems. To fix them I had to build a French drain. Its time to upgrade the drain and do a little grading.
Here I have dug a new trench at the end of the barn with the drainage problem.
I waited until we had a thunder storm and used the standing rain water as a guild to help me properly grade the drain.
After the grade I had to build a bridge so my tractor could access the inside of the barn for little grade maintenance.
I took several inches off the high end of the barn. I made sure the inside of the barn floor stayed higher than the outside grade.
