Highway designers often are faced with the problem of controlling seepage out of a highway cut face. The article describes one solution to the problem that was applied in Saddle River Borough, N.J. The problem involved not only groundwater flow, but also direct storm runoff which had eroded small watercourses down the steep face of a hill. A low berm was constructed on the low side of the hillside approximately 20 ft from the edge of the road. A shallow basin was also scooped out on the upstream side of the berm and a pipe was used at the low-flow outlet for the tributary area. A large diameter pipe placed in the basin serves as the collection and discharge point, and an emergency overlow weir and spillway handle flows exceeding the capacity of the outlet pipe.
