Work Under Design:

 

Design work is underway on the following projects for letting in 2020.

1)         The Mason Avenue bridge was severely damaged by flooding on the Little Sioux River in July 2018.   The bridge has been closed to traffic due to damage caused by the bridge being struck by a large tree.   The county engineer’s office was notified that FEMA has determined that the damage is eligible for repair/replacement assistance. The county road department has filed required documentation requesting assistance from FEMA with eligible costs and has started work on design of a new bridge at this location.   Preliminary design work is underway for a 209’ x 24’ continuous concrete slab bridge that meets the hydraulic requirements of this crossing.   There will still be road grade overflow on both sides of the bridge for extreme flooding, similar to the way the current truss has worked.   We will be submitting the design to FEMA shortly to obtain approval for an improved project.   We expect the bridge replacement project will be undertaken in 2020.  

 

2)         Design work is starting on a project to replace the K64 pavement from Highway 141 north to Old Highway 141. This work includes new pavement through the town of Hornick.   The project is proposed for letting in spring 2021.     

 

Other Projects:

 

1)         Iowa DOT is starting a bridge project on Highway 141 next week.   County roads including K67, Old Highway 141 and K64 will be used as detours during construction on the project.   The detour started on Monday, May 4th. A temporary stop sign has been placed for both directions of travel at the intersection of Hancock Avenue and Old 141 during construction to improve safety at this intersection.   It will be a four way stop for the duration of the project. A fall 2020 completion date is anticipated.

2)         Iowa Highway 31 will be closed for repaving in September 2020 between Washta and Correctionville. During this time, County Route L36 will be used as part of the detour. Right now, we are anticipating the detour starting the week of September 8, 2020.

 

COVID Impacts:

Woodbury County secondary road department revenues are being adversely affected by the reduced level of travel and reduced commerce related to COVID-19 precautions.   Our largest revenue sources are Road Use Taxes and Local Option Sales Taxes.     Total fuel tax receipts are reduced due to lower state-wide travel levels. Road use tax receipts are also affected by registration fees and vehicle sales, which are also down. The latest projections for fuel tax revenues are that we will be 25-30% lower for the last quarter of FY 2020.   This translates into a $325,000 to $400,000 loss to our road funds potentially for April-June.   At the same time, our local revenues are heavily affected by reduced sales taxes, as we receive just $1,450,000 in property taxes for FY 2020, but anticipated $2,000,000 in Local Option Sales Tax revenues. This primarily affects our local expenditures and projects. Depending on the duration of budget shortfalls, next fiscal year may involve delays in locally funded and let construction projects.   The department’s emphasis with reduced funding will be to maintain the county’s current level of maintenance, including gravel purchases and snow removal.
