Combine flat land with a thick clay subsoil and you'll get standing water regardless of the level of vegetation.

I think most people on the forum are aware of our subsoil composition from the excavation photos. Nothing about that will change. The water absorption of clay doesn’t diminish the effectiveness of denser vegetation that slows horizontal movement of storm water. There’s a multiplying effect of tree and brush canopies capturing, scattering and evaporating some precipitation. The decomposition that occurs in heavily vegetated area naturally builds up an absorptive topsoil that captures and slows surface runoff
