When they met Tuesday, Leavenworth city commissioners approved two design contracts to address flooding issues.

One contract is with Wilson & Co., Kansas City, Missouri, in the amount of $33,900 for the replacement of a culvert at 14th and Pawnee streets.

Public Works Director Mike McDonald said the design work should take about 90 days. The construction work can take place next year. It is estimated the replacement of the culvert will cost about $300,000.

McDonald said the culvert replacement is only one part, or phase, of a larger project that is needed to address the flooding issues in the area. It is estimated the entire project would cost between $1.3 million and $1.4 million.

City Manager Paul Kramer said this project involves flooding related to a drainage basin, most of which is located on the U.S. Penitentiary grounds.

He said city officials have tried to work with the federal government regarding a cost effective solution involving USP land.

“We have been unsuccessful at every turn,” he said.

The other design contract that was approved Tuesday involves a planned detention basin at the north end of 16th Terrace.

This contract is with Water Resources Solutions, Prairie Village, for the amount of $38,665.

This design work also should take about 90 days, and construction can take place next year, McDonald said.

It is estimated the detention basin will cost about $350,000.

McDonald said the detention basin will be constructed on property owned by the city.

He said the detention basin also is only the first phase of a larger project to address flooding issues in this area of the city. It is estimated this entire project would cost about $1.4 million.
