Engineers who will be designing Minot's flood protection system visited with community representatives Wednesday to find out what residents want that system to look like.
Members of Minot city staff and the Minot Flood Recovery Committee met with representatives of Barr Engineering as part of a three-day workshop.
Engineers came away with a long list of buildings and facilities, in addition to individual homes, that the city would want protected. The list included business centers, recreational facilities, schools, the city's water wells and treatment plant, historic districts and connector roads. Participants also helped identify areas where potential hazardous material storage creates special dangers in times of flood and areas where environmental concerns could slow up the project's development if enveloped by the project.

Barr Engineering presented options for a dike system. Existing dikes could be raised, although there are some pitfalls in that plan that include a higher risk of dike failure. Other options involve setting back the dikes, which allows for a wider river and lower dikes, and then excavating the sides of a wider channel to create more depth.
Tim Fay, the project's manager with the State Water Commission, said the flood control system is likely to be a patchwork of the options. Setbacks or deeper channels won't be possible in some areas, such as the area around the water treatment plant where facilities and roads inhibit widening, he said.
The models presented by engineers provided for up to a 600-foot-wide corridor where properties would be acquired to make room for the flood protection.
Participants also discussed the possibility of altering major bridges or removing pedestrian bridges to provide for more flow and keep roads open. They touched on specific alternatives, such as straightening the channel where the river flows across 27th Street Southeast.
Discussion continues today, beginning at 8 a.m., in North Central Research Extension Center.
