Please provide a photo as we would like to resolve this matter.

The morning after my original posting about erosion of this dirt area, a RIOC crew was out working on the problem -- by putting up boards to stem the flow from the west edge into the RY Management area -- so it's obvious that a photograph isn't necessary. The only thing that's still needed is a bit more blockage on the south edge -- the flow still goes around the uphill (east) end of the concrete slab, and another slab or two should fix that.
Plantings in that area, which is a desolate mess, would be a big help in preventing soil runoff, not to mention making it look a lot better. Where are the promised 3 young trees to replace the big one that was removed in mid-April because its roots were damaged?

Here's a photo of the southwest corner, with the concrete slab on the south edge. Runoff still occurs uphill from the east edge of the slab -- see both the dark soil and the light soil to its right.
The photo also illustrates how barren the area is...

I responded (twice), more than 2 weeks ago, to the request for a photo of the problem. It should be easy to fix -- why the delay? (And why the lack of acknowledgment of my response to the request?)

This issue has since been corrected.
Thank you for reporting.

The problem has NOT been resolved!!! I noticed a sizable amount of soil runoff a few days ago. Please give this serious attention. There's no point in losing the soil, which will be needed if you ever get around to doing some planting in that barren area. Also, the soil on downstream paved surfaces is dangerous for anyone on wheels (especially children).
