Danbury is seeing a population increase, including families with kids. That means higher enrollment in schools. Mayor Mark Boughton plans to propose this summer a plan to expand the lower grade buildings to accommodate that increase. He noted that with the DHS expansion, with the worst case enrollment scenario, there's room in the middle and high schools.  He wants to make Mill Ridge Primary School and kindergarten through 5th grade facility.  King Street Intermediate could become a K-5 STEAM academy for Science, Technology, Engineering, Art and Math.  Boughton says at Mill Ridge Primary there's room on the campus to expand the building with traditional brick and mortar.  He says there's a need for 13 classrooms.  For the two schools, he estimated the cost at about $30 million.
