Any ideas to fix this issue?
The yard slopes towards the flowerbed, which sets about 3 feet above the sidewalk you see on the far right. This one area floods and water sits until it evaporates if it rains, I water the yard, or I water the flower bed. The retaining wall does have pipes on the streetside for water to drain, and they do flow sometimes for several days after heavy rains when the yard itself appears otherwise normal. There's a lot of clay.
