All along, Cedar Rapids city officials knew that the city’s voluntary flood-recovery buyout program would leave a small number of uninterested property owners with their properties standing in place.And the city knew, too, that some of those would be in the way of the city’s coming new system of flood-protection levees and flood walls.On July 22, the City Council will take a first soft step to signal to a small group of property owners remaining in the flood-devastated Time Check Neighborhood that the city’s coming flood-protection system will require the purchase of their property.The council is slated to discuss the imposition of a 90-day moratorium on any substantial building or development activities on those properties.
