Frank, Dave Foster and I stopped by the Million Air ditch earlier and noticed a few items of concern: 1. The electric generator they were using did not appear to be properly grounded. 2. They dug sediment from the bottom of the ditch and laid it on the banks. I am concerned that it will erode and cause problems for the airport within their drainage network. Is it possible to place a rock check dam at the headwall for the 2-66” pipes? It may help prevent any erosion that may be occurring with this work. If you have any questions, please let me know.
