Anderson Furniss holds a factory he built as students at Blackridge Elementary School in Herriman get a lesson in building a city from scratch Monday. City planners from Lehi, Draper, Sandy, Herriman and Riverton spent the day with the students, who built little cities to scale using Styrofoam. The students even had to go before a planning and zoning commission to get their new buildings approved.
