A spring start is expected for the work planned at Mid-Prairie Middle School.Using money from a bond issue approved by voters earlier this year, an addition is being built for the district’s Home School Assistance Program and a geothermal system is being installed. According to Superintendent Mark Schneider, the design for the geothermal system came in over budget. To bring the cost down to the original estimate, the gym will not be air conditioned. Schneider adds construction is slated to begin in early April.
