Project Status

Should you wish to receive regular construction updates as the project progresses, please provide your email address to dwilwerding@cityofjohnston.com.

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. As the project is about to kick off we wanted to be sure you were aware of important information related to the project:
  • Prior to commencement of construction, construction fencing will be installed throughout the project area to clearly delineate the construction limits for the project.
  •  Initial construction activities will include clearing and grubbing of the trees and landscaping that need to be removed throughout the entire project area.
  • Following clearing and grubbing operations, construction will begin at the downstream eastern portion of the project closest to Beaver Creek. The project has been broken into five separate phases and will generally move from east to west.
  • 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.
We recognize this construction is occurring in your backyards and we will work with the contractors to do everything we can to limit disruption to your neighborhood. However, the project will require large construction equipment and take several months to complete, so we ask for and appreciate your patience throughout the project.

Project Description


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.

Project Funding


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.
