Building a sewer line to a potential Davenport casino near the interstates 80 and 280 interchange could take up to three years and $12 million — although a timeline could be accelerated, aldermen heard Wednesday.

During a presentation to aldermen on the third phase of the westside diversion tunnel by Public Works director Mike Clarke, Mayor Bill Gluba asked about a sewer line to the potential casino site.

Estimated at about 4 1/2 miles, Clarke said the project could take 18 months to design and just as long to build at a price of $10 million to $12 million.

The proposed casino’s projected construction timeline is 22 months.

In designing a sewer line project, several factors, including topography and land ownership, have to be considered, so that possibly as many as six alternative plans could be developed.

City administrator Craig Malin told the council that if a $100 million development were to go into that northwest Davenport site, the city would call on the resources necessary to accelerate construction of a sewer line.

The third and final phase of the diversion tunnel is estimated at $6 million and won’t reach the depths of the second phase, which went as deep as 160 feet in places under the city. The third phase will go about 12-15 feet under Duck Creek and will close the bike path for a time.

Estimated at $33 million, the tunnel’s highly technical second phase is likely to cost less than $20 million. Alderman Nathan Brown, 1st Ward, asked if Clarke expected more bidders since the work is less specialized. Clarke said the third phase will involve excavation and pipe installation.

“We will see how favorable the bidding climate is,” Clarke said.

Alderman Ray Ambrose, 4th Ward, raised concerns about security around the project, with a trench 20 to 45 feet deep at times. Clarke said temporary 6-foot chain-link fence will be put up around the work.

Clarke also answered questions about snow and ice removal in residential areas, but mostly received praise and understanding from aldermen.

Clarke said heavy rain that turned to ice under snow followed by unfavorable temperatures for melting has made removal difficult. The average life expectancy of a road grader blade used to remove ice is about five hours.

Salt is being put down, but temperatures need to be in the 20s for it to be effective, so the cold temperatures haven’t helped in the removal process, Clarke explained.

Alderman Sheilia Burrage, 5th Ward, described her street as “an ice skating rink.”

“I hope everyone understands, the weather is causing the problems, not public works,” she said.

Clarke said that people with specific issues should call public works so they can be addressed.

Alderman Barney Barnhill, 7th Ward, said he has received some phone calls about clearing streets.

“Once you explain it, people were OK,” he said.

In other action, the council learned that budget meetings will begin Jan. 12.

$12,000,000.00 could plow a lot of streets and buy plenty of salt. BTW, the secondary streets of locust remain ice-packed and dangerous. But now i'm just being far too practical.


On top of the $42 million? Now it's $54 million. What about the other parts of the power / utility grid updates that will be required?


I think you guys are missing the mission here. Do you REALLY think that the city wants the casino out by I80/I280? They have been vocal the whole time about keeping it downtown. They have this $12 million dollar price tag for a reason, to keep it downtown.

Do you REALLY think that the city cares what you think about spending your money?


The sewer project isn't worth commenting on, it's obvious the City leaders are going to push through on this regardless of practicality and cost.
Aldermen...the street conditions are a result of the weather AND the lack of the city doing their job appropriately. I've been on Bettendorf streets and they were immediately treated to prevent the ice build-up we have in Davenport. Correct, you cannot plow and salt AFTER everything has frozen. Now we just have to wait for it to melt. What you should be asking is why and how it got this way in the first place!


$46M + $12M = $58M....Oh well, what's another $12M in borrowing when the city will have all those millions rolling in each year?

Force the taxpayers into owning a casino business.

Borrow $46M to $58M.

Without asking the citizens and taxpayers if they approve of either action....That's what I call democracy in action!


You've got be kidding. Three years and twelve million dollars? In the photo above it appears they are building concrete forms from wood. Whatever happened to precast concrete sewer lines?


Did these people ever think to ask the taxpayers (voters) what they thought about all this money being spent on this fiasco? This city places to much stock in gambling and not enough in bringing in long term manufacturing and businesses. I guess it's easier just to spend money instead of recruiting industry.
