Crabtree Creek Trail Retaining Wall Project

Greenways

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.

This phase is complete.

Construction

On July 09, 2020 project staff identified some additional improvements necessary to complete the project which will require additional time to construct.  These improvements will require additional material fabrication and construction which may unfortunately extend the project completion into November 2020.  

As volatile as Crabtree Creek can be during storms the City of Raleigh wants to ensure this project is constructed to withstand the frequent high-water events which causes so much damage to structures along Crabtree Creek Greenway.  The City is confident that once this project is completed the final retaining wall will protect this section of the greenway from any future erosion or damage.

This project is now complete.


History

The Capital Area Greenway System was first adopted by City Council in 1976. This plan proposed a system of linear parks located primarily along rivers, streams, and creeks, and included the opportunity for an interconnected system of pedestrian trails across the region.
