Dave went to the property today and did an informal measurement regarding the line of sight issue that I wrote about last week. He knows he can raise the road into the property 9 inches above grade, if necessary. Right now it's 4 inches below grade, giving a 13 inch difference, if needed. Based on that, and the measurement from the road to the hill that is creating the possible issue, that brings us somewhere between really close and over the requirement. He has already booked a surveyor to come out, and hopefully they'll confirm his findings from today.
