The attached resolution authorizes the award of the public improvement contract for the

The existing sewer located along Southgate Drive is damaged in several locations.

replacement.

The project will provide for the replacement of 276 linear feet of 8-inch diameter sanitary
sewer main having a depth of fourteen to twenty-one feet, including the replacement of
two sanitary sewer manholes, restoring sanitary service lines, crossing water main and
other utilities, and pavement removal and replacement.

The City received sealed bids on February 20, 2025 for the Southgate Drive Sanitary
Sewer Improvements Project. Tschiggfrie Excavating of Dubuque, Iowa submitted the
