How can I fix a SERIOUS drainage problem by my front porch?
We live on a rural hillside & during heavy rain, water rushes down our gravel driveway, makes a 90° turn, and pools in the parking area under our carport;
the sidewalk runs parallell and, over time, it has sunk to the point that it is now below ground level. Last year, we laid patio blocks on top of the sidewalk (after 1st photo was taken) but the added weight has caused it to sink even more (sometimes it is completely under water!) We tried trenching out an area (2nd photo) but that helps only with yard drainage, not the parking area.
Can someone kindly tell these senior citizens the most cost-effective way to solve this problem? Any help is much appreciated!
