Addressing basic repairs in all 142 D.C. public school buildings will cost an additional $120 million in the coming year, on top of the roughly $80 million already spent to rehab dozens of facilities and upgrade a handful of athletic fields, city officials said Wednesday.

The $120 million will finance essential and long-neglected repairs at roughly 70 schools — including fixing roofs and bathrooms and clearing health- and fire-code violations. It will also be used to ensure heat and air conditioning systems are installed and working in every classroom.
