Boulder High School is in the middle of the Boulder Creek flood zone . The school 's adjacent soccer fields were the site of housing as late as the 1970s , but the houses were removed due to the flash-flood risk . The City of Boulder continues to remove residential buildings in the path of the most dangerous portions of the creek , replacing them with parks and fields . The Boulder Creek 100-year flood took place in 1894 , destroying all buildings in the area . The 2013 Colorado floods caused the school to be closed for several days . Serious water damage was reported in several areas of the building , including many classrooms , the weight room , and the cafeteria . The soccer fields flooded , as did the softball field , which was the most damaged
