The top picture shows the drain/culvert on the east side of the house. Before we installed the drain system on the west side of the house, all water from the west side traveled across the front of the basement and went down the east drain. I put a 90 degree elbow on the end of the pipe you see here, and I cut a hole in the bottom of the drain box for the other end of the elbow to go through. The top is a 20 inch round grate that is rated for 1,000 pounds.
It took about 12 wheel barrow's full of dirt to fill the hole. I then put plastic over the box and cut out a hole in the center, then raked the rock over everything. No more tripping hazard and there should be a lot less soil erosion.
