Underwood Park History In 1964, plans were approved for Maplewood Park, a 10-acre facility off Linden and Jersey. The project would cost between $70,000 and $80,000 and would take several years to complete. It included an outhouse building, multi-purpose area for basketball, shuffleboard, ice-skating and volleyball. In 1982, the park was renamed Underwood Park in honor of Robert C. Underwood, a former Illinois Supreme Court Justice and an active member in the Normal community. In 2007, another 6 acres was bought to expand the size of Underwood connect it to Constitution Trail.
