Work Under Design:


Design work is underway on the following projects for letting in 2019.

1)         250th Street Grading Project - 2.25-mile grade for paving project south of Anthon.   Right of way will be necessary to allow construction of this road.   Final design is complete.  Plats for right of way acquisition are complete and acquisition has started. We completed right of way negotiations with landowners, but we are awaiting one signature on the agreement. We are working toward a July 2019 letting. This project is funded with the $1.3 million per year special project levy funds.


2)         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.   We expect that work to be completed in 2020 at this time.                     



3)         The county engineer is reviewing the cost to improve Benton Avenue south of 120th Street. The engineer will report estimated upgrade/improvement costs to the board ahead of their June 11, 2019 meeting.   Benton Avenue is a dead-end gravel road with several residences on either side of the road. For the second time in 10 years, the road suffered from severe instability during spring thaw. Options for improving the road to assure access are being explored by the Board and county engineer.
