The cost of Davenport's East River Drive resurfacing project is going up.

Alderman will vote next week on a series of 22 change orders totaling $1,199,066 for additional work done on the project that was originally budgeted at $2.36 million.

"The project became more significantly complicated than what we first expected," said Alderman Ray Ambrose, 4th Ward, who chairs the Public Works Committee.

The list was presented to aldermen Wednesday at the Committee of the Whole meeting.

A final stretch of East River Drive between Oneida Avenue and Mound Street that didn't get resurfaced last year because of delays caused by the sewer repairs was to start this week, but was delayed by weather. It is uncertain whether the project would be further delayed by Mississippi River flooding.

The change orders range in cost from $25,293 to $133,774. The most expensive was for a complete reconstruction of the storm sewer system at College Avenue and East River Drive.

Before starting resurfacing last year, the infrastructure was investigated and a number of sewer lines were televised, but some were blind connections and couldn't be viewed, according to a city fact sheet.

The change orders included disconnecting sanitary sewer lines from storm sewers, replacing failing pipes, correcting the size of pipes used, resizing catch basins and replacing brick manhole structures.

When announced earlier this month, the resurfacing of River Drive from Oneida to Mound was expected to take until July.
