the concrete spillway was already there, it isnt an emergency spillway, its the only way water leaves the pond. the couple works in the yard all day, usually using a small garden/lawn tractor pulling a trailer. he wanted us to pave the top of the dam so he would have a better walking surface, place to drive his tractor smoothly, and drive the mini suv to side of the house to unload groceries. they were great customers for me this past year. we paved there main driveway also early this year.
