HANNIBAL | It will likely be close to the spring flood season before the temporary repairs to the North Street storm sewer begin, according to Mathew Munzlinger, interim general manager of the Hannibal Board of Public Works.
During the December meeting of the HBPW Board Munzlinger reported that Poepping, Stone, Bach & Associates, the engineering firm hired earlier this year by the HBPW to conduct a preliminary engineering investigation of the damaged storm sewer, had been working on putting the necessary documents together for the project.
“We are working with the engineer to complete the bid package and have it available for contractors in the next couple weeks,” Munzlinger said earlier this month.
Munzlinger offered a tentative timeline regarding when the work might begin.
“The plan would be to receive board approval of the contractor at the February board meeting. That would put it in early March before any work could likely begin,” he said.
The temporary fix would not be performed by HBPW personnel.
“This is something that would be completed by an outside contractor that specializes in this type of work,” Munzlinger said.
Once the contractor begins working the repair should not take too long to complete if weather conditions cooperate. “We are hoping (the project will take) only a couple of weeks from start to finish,” Munzlinger said, adding that the work will be “extremely weather dependent.”
The HBPW Board approved late last year undertaking a temporary repair that is intended to get the storm sewer, damaged during a torrential rain event in May 2019, through the upcoming spring flood season.
The least expensive of the permanent repair options will cost in the neighborhood of $5 million to $5.5 million. The HBPW's storm water utility currently lacks the funds necessary to undertake a permanent repair.
In contrast, it is estimated that the temporary repair, which is intended to prevent further damage from occurring to the downtown storm sewer, will cost approximately $60,000.
