The new retaining wall located on the Crabtree Creek Trail at Mile Marker 12 between the trail access at North Hills Drive and the Mine Creek Trail opened on December 15, 2020.
High levels of rain and stormwater runoff caused excessive erosion and damage to the streambank and previous retaining wall.
A unique design approach was used to replace the wall utilizing steel piles embedded into the rock below the stream and a sheet pile wall placed behind the piles. To counteract the overturning of the wall, tie-back anchors were installed.
