Rolling Dip Timelapse - Sonoma RCD

This is a timelapse video of a road drainage feature called a rolling dip. Rolling dips are used to help roads drain more efficiently and to disconnect road surface runoff from draining directly to streams, thus improving the longevity of the road and reducing road related sediment from entering nearby waterways. This was a part of a larger project implemented on a ranch in Sonoma, CA and funded by the State Coastal Conservancy and the State Water Resources Control Board. Sonoma RCD managed both grants and worked with Campbell Grading to implement the road work. Note that both a bulldozer and an excavator where used for this particular rolling dip, but the work can also be done using only a bulldozer.
