 KNOX Newstime is 530. The City of Grand Forks says that starting Monday, crews will begin maintenance work on the concrete floodwalls along the Red River. This work may result in crews needing to work within the easement on the dry side of the floodwall. The maintenance is for concrete floodwalls only and not the earthen levees. The maintenance work is expected to be finished by the end of September, weather permitting.
