Linwood ? City officials say they need Leavenworth County’s help to stop erosion along Stranger Creek that’s threatening Linwood’s water supply.

The well that supplies Linwood with water is about 200 feet from the erosion site, said city worker Dwayne Call.

The project, designed by the State Conservation Commission, calls for the eroded area of the creek to be filled in with shot rock.

John Zoellner, the county’s director of planning and zoning, said the project included eight weirs, structures similar to levees. Those weirs, set around the sides of the creek, divert the flow of water.

Call said the city could supply labor for the project, but it could not afford the rock. Instead, the city wants the county to supply it from a quarry at Tonganoxie. Phil Balch of the State Conservation Commission estimates the Stranger Creek project would take about 2,800 tons of rock.

County commissioners learned about the project earlier this week but say they have to know more about the quantities and costs before they can commit any resources.

Balch said that in rural areas of the state such stream bank projects cost about $13 a foot. In this case, the size of the project is about 1,150 feet, for a cost of $14,950. But being near urban areas doubles the price, he said. For example, a project along the Neosho River cost about $20 a foot. If costs reach that much in the Linwood project, the total would be about $23,000.
