Green Meadows West Central Channel Stabilization Project
Should you wish to receive regular construction updates as the project progresses, please provide your email address to firstname.lastname@example.org.
On November 6, 2017, the Johnston City Council awarded the construction contract for the project to Synergy Contracting, LLC from Bondurant, Iowa. Synergy and their subcontractors will be responsible for completing the project. Construction is anticipated to begin the week of November 13, 2017, with progress throughout the winter with a targeted completion date of May 31, 2018.
The following is a brief construction status as of January 22, 2018.
The first phase of the project, the easternmost portion of the project closest to Beaver Creek, is complete except for some final grading, this will occur as they work on the second segment and have excess soil available to move to this phase.
The contractor has finished most of the grading needed in the second phase, which is the central portion of the channel between Foxboro Road and Beaver Creek. Toe rock/rip rap is being installed on both sides of the stream through the second phase of the project currently. The contractor plans to have the rock placement and riffles within this phase completed within the next 2 weeks, depending on weather.
The current plan is to begin construction within phase 3, the area immediately east of Foxboro Road at the outlet of the box culvert which drains under Foxboro Road around the week of February 5.
To ensure the construction occurs within the designed parameters, the City has contracted HR Green to provide a Construction Inspector who will be onsite monitoring construction activity anytime the contractor is working. Josh Babcock is the Construction Inspector who will be onsite, should you have questions or concerns during construction he can be reached at 515-205-5731.
Construction access to the project will be provided via Foxboro Road to the eastern portion of the project and Foxboro Road and Hadfield Circle for the western portion of the project. This activity will require increased truck traffic and intermittent lane and sidewalk closures. Please use caution as you are traveling through this area.

This drainage channel is located on outlots owned by the Green Meadows West Homeowners Association, and runs between Hadfield Circle and Heather Bow west of Foxboro Road and Heather Bow and Tiburon Circle east of Foxboro Road. The purpose of the project would be to correct erosion and to stabilize the stream banks from the outlet of the storm sewer project completed in 2010 easterly to Beaver Creek.
The Green Meadows West Central Channel Stabilization stormwater improvements are 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, for more information on the stormwater utility, visit the stormwater projects page.
