Don't Mess with Mother Nature...I am sure that we have all heard that expression at one time or another. The natural order of things has been disturbed on this small lot and Mother Nature is not taking it well.
She has her left hand on her ample hips and her middle finger is pointed at the folks who have little or no concern for her hard work or the survival of the planet. The earth is the very best water maintenance system ever created. When the soil is left to do its job, much of the water is absorbed and we never see it. It goes where it fmay do some good for all of us. Once this system is disturbed by heavy bulldozers and the removal of the protective layers of earthworm worked topsoil, Mother Earth gets quite testy.
The complainers have created a real problem here in making this water slide made of dirt The high end of the garden still mostly subsoil since no topsoil has been replaced in this area. The soil remaining there is composed of a fair amount of clay. This clay has been packed tightly eliminating air spaces. Water slide anyone? Simple physics. Turn the soil on the high end. There is no danger of sinking into soft earth in that area. Soften up the earth so it will absorb the rain, duh. That is if we are really working together to get our garden back to normal and to protect area residents from flood and mosquitoes.
One wonders why the persons who complained about vegetation at the end of the season did not also complain about the absolute lack of drainage in the entire area. Perhaps that is a problem that has grown more unpleasant over time. Check out this corner where the water is accumulating. Take a walk in your neighborhoods and make a note of where the drainage gates are located. I took that walk in this neighborhood in the company of one of the residents. If I am not mistaken, I think drainage falls under the heading of City Engineer. Perhaps he has been left out of the equation for long enough.
