April 30, 2019 - Contractor is scheduled to be on site in Mid-May to begin survey and preliminary clearing activities. Residents along the project will be notified prior to construction. 

A public meeting will be held on May 9th from 4:30 – 6:30pm in the multi-purpose room at City Hall. It will be an open house format. Information will be available on timelines, impacts, and road closures. 

April 30, 2019 - Contractor is scheduled to be on site in Mid May to begin survey and preliminary activities. Residents will be notified prior to construction. 

April 1, 2019 – Contractors are currently bidding on the project. A contractor should be on board and ready to begin in May. Construction is expected to last through November 2019. A more detailed schedule with be available after a contractor is selected and residents will be notified before construction begins on their property.

December 17, 2018 -  Easement documents will be going out in the mail this month. A letter will be included in the mailing that explains the process for signing easements. to The city will be working on acquiring all the easements in January. You may see utility companies in your neighborhood this winter adjusting their facilities for this project.

October 10 - The City has completed preliminary plans for this project. Staff has been coordinating individually with residents adjacent to the channel improvements. A public meeting will be held October 24 in the Multi-purpose room at City Hall as an opportunity to share the design with the neighborhood and receive feedback from residents. Please come anytime between 4:30 & 6:30 p.m. as there will not be a formal presentation. City staff and the engineers will be available to discuss the project. 

August 9 – Preliminary design continues for this project. Coordination has also begun with utility companies to plan utility relocation that may be required as part of the improvements. 

Individual resident meetings will begin in September to review the preliminary design with property owners adjacent to the improvements. After individual property meetings occur, a public meeting will be held to review the project and schedule.

Construction is currently planned to occur in 2019.

March 29 - Progress is being made and most of the field surveying is complete. Utilities have been located and surveyed. During the week of April 1, 2018, four locations will have soil borings taken to determine sub surface information. View the Soil Boring Location Map here (PDF). Once that is complete all the utility flags can be removed from properties.

We are now starting the detailed design based on Option 3 of the Preliminary Engineering Study. As we develop the design we may have meetings with individual properties along the way. Once preliminary design is complete we will have a resident meeting.

February 27 -
A letter was sent to residents of the neighborhood to make them aware of the current status of the project. View the letter here.
