Raising Columbus Junction’s levy has become a team effort. Federal, state and local officials have been enlisted to asses the project and its costs. Columbus Junction city council member Harold Prior says they hope to lessen the roughly $600,000 price tag by using local soil. One snag in the process is the impact it might have on local wildlife. The Army Corp of Engineers requires a wetland charting, which could take several weeks. A review of the charting by the Corp of Engineers might not be completed until late this summer.
