Project Description: This project will include bank stabilization along the pedestrian trail located south of Timberwood Drive and west of Long Meadow Drive in Greenwood Hills Plat 3, immediately upstream of improvements completed in the last several years in the Greenwood Hills Greenbelt. This project is located on property owned by the City and will focus solely on stabilizing the creek banks which are threatening the trail, primarily through the use of rip rap and sheet pile walls. A portion of the trail will need to also be reconstructed following completion of the stabilization work.
Project Funding: The Timberwood Drive Trail stabilization project is funded by the Johnston Stormwater Utility, which was implemented in July 2012 to create a dedicated funding source for projects that reduce erosion, protect properties and infrastructure from flooding and to improve water quality within the City of Johnston.
