The heaviest spending to overhaul the city’s four Combined Sewer Outfalls (CSOs) is slated to occur FY22-23, with expenditures in each year exceeding $100 million. Similarly, $259 million (over half) of the school system’s CIP spending will occur FY21-23. Among other capital expenses, those years contain three major construction projects: additional high school capacity, swing capacity/new future school, rebuilding Douglas MacArthur Elementary School.
