Buildings will have more space, other improvements February 3, 2021 | 10:31 am February 3, 2021 via MCPS The Montgomery County Board of Education last week gave its stamp of approval to major projects at two schools: Burnt Mills Elementary in Silver Spring and Poolesville High School. Both school communities have long advocated for updates to their aging, crowded facilities. Burnt Mills is built to hold about 390 students, but has an enrollment of 600 students this year, according to MCPS documents. The school opened in 1964 and was last renovated in 1990. New plans call for a complete rebuild of the school, so it would be able to hold 647 students. There will be 100 parking spaces, as well as an expanded bus loop and dedicated student pick-up and drop-off areas, according to project documents.
