The Carroll County Board of Supervisors Monday approved $700,000 in waterway projects scheduled for completion by the end of June.

The five projects include three box culverts, a new bridge and a streambed stabilization around the county. In all cases, the projects' winning bids came in well under engineers' estimates.

County Engineer Dave Paulson opened bids Monday morning in the Carroll Courthouse, an event attended by several contractors involved in the projects or seeking to be.

"It looks like you had some very active bidding," said Carroll County Supervisor Gene Meiners.

At $193,622, Cunningham-Reis Co. of Van Meter was the low bidder for the Grote Bridge project, the removal of an old bridge and placement of a new 70-by-30-foot bridge on Kittyhawk Avenue roughly 1 mile north of Mount Carmel. The bridge traverses Storm Creek, otherwise known as Drain 23. The bridge is named after the late Paul Grote of Mount Carmel, Paulson said.

The current bridge is too small and narrow.

At $199,544, Murphy Heavy Contracting of Anita was the low bidder for a streambed stabilization 2 miles south of Manning and south of 330th Street over the Nishnabotna River. The project involves the placement of a 6-foot-tall sheet-pile dam aimed at improving streambed stabilization so structures downstream aren't in as much jeopardy of deteriorating due to a deepening river bed, Paulson said.

The streambed work is expected to have the added benefit of improving the well performance in the West Central Rural Water field. West Central provided $50,000 in funding for the project, and Hungry Canyons Alliance, a western Iowa collection of 23 counties with a mission of controlling stream erosion in the Loess Hills, financed it with $200,000 in state and federal money. Original estimates placed the project at more than $300,000, Paulson said.

"We have good contractors," Paulson said. "We're getting low bids from good contractors. You just can't beat that."

The county also approved construction of three box culverts.

At $88,139, Richards Construction of Sac City earned the low bid award for a project on Birch Avenue about 2 miles north of Arcadia. Richards also was the low bidder on the culvert being built 2 miles south of Lidderdale on Robin Avenue at a cost of $83,974.

At $135,378, Midwest Contracting of Marshall, Minn., was the low bidder for a culvert 2 miles north of Manning on Birch Avenue.

The supervisors voted 5-0 to approve all of the low bids.
