Crabtree Creek Trail Structure #106 New Repairs

The City of Raleigh has closed a section of the Crabtree Creek Trail between Capital Boulevard and Mile Marker 7. This map shows the location of the closed section of trail. Boardwalk structure #106 of the was constructed as part of the Middle Crabtree Creek Greenway project in 2003. The original boardwalk construction incorporated standard timber pile construction typical of boardwalk design/construction and is consistent with methods applied to other boardwalk structures constructed throughout the Capital Area Greenway System.

At the time of the original construction, the eastern streambank of Crabtree Creek along structure #106 provided adequate stability to support timber pilings with concrete base installations. Since the completion of this project and over time, the stream banks of Crabtree Creek in this section have become significantly eroded which has caused scouring of the concrete pier footers exposing them and subsequently leading to structure failure.

In April 2018, two shorts sections of structure #106 were damaged and repaired as a result of several storm events including Hurricane Matthew.

Due to the continuous scouring of Crabtree Creek’s stream banks along this section of trail, the design and construction methods used in this repair incorporated steel pilings imbedded into bedrock rather than timber piles and footers. With the potential of continued scouring, the steel piles embedded into bedrock was the best approach. This is an improved design to the original method of construction. Since the April 2018 repair, structure 106 has experienced two additional areas of extensive damage due to storm events, continued stream bank erosion and surface water run-off from adjoining properties. The April 2018 repair was not compromised as a result of the most recent events.

This phase is complete.


In the Spring 2019, Park staff completed two (2) feasibility studies; repairing the existing timber boardwalk structure and two (2) trail realignment options. On August 20, 2019 the City of Raleigh City Council approved the recommendation to move forward with the design and construction of the Option #1 to reroute this section of the Crabtree Creek Trail around the damaged timber boardwalk structure and to construct the trail at-grade along an existing sewer easement and along the existing Ratchford Drive.

Staff has contracted with Dewberry Engineering to complete the design, permitting, bidding assistance and construction administration for the staff recommended realignment option #1.

This map shows the alignment of Option 1 as well as the other options considered.

Once the final construction plans and permits have been approved the project will be publicly bid for construction.


Phase details coming soon.

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.
