Late this morning, we had another intense monsoon here in town. It was not as bad as the July 18th storm, but the road in front of the house flowed for about fifteen minutes with runoff from higher terrain to the west and north. These Arizona monsoon thunderstorms sure do dump a lot of rain in a short period.
The retention walls we had built continue to do the jobs we intended for them. The wall in the back wash diverted runoff to the west side of the property and the wall around the RV drive kept runoff from the hill behind us from coming onto the driveway (mostly). The front wall, seen in the twelve second video above directs the flow downstream on the road rather than eroding the frontage any further.
I panned the camera from west through south to eastward down the road. It was still raining as I made the video, albeit not as hard as during the peak intensity ten minutes prior to this. After these last two episodes of rain, we can know that our money building walls and paving the RV drive was well spent.
