Summertime is a busy time for maintenance crews in North Wasco County School District 21.  D-21 Chief Financial Officer Randy Anderson says the district’s maintenance personnel are busy “flipping” school buildings to get them ready for the 2019-20 school year, which means full deep cleanings of all of the facilities.  Chenowith Elementary is an especially busy place as it hosts 300 students in a migrant education program for the families of those working the cherry harvest.  Anderson says that will continue through the end of July.
