Site work and paving for a mixed-use development in Riverdale, Iowa. Completed plans call for site work for a road / highway; and sidewalk / parking lot.

The design and construction between State Street and a point 75 feet northwest of the CPKC crossing will be funded by the City, and the portion that is 75 feet on both sides of the crossing will be funded by a grant through the State of Iowa State-Aid Grade Crossing Surface Repair Fund.
