In 1967 and 1968, Tranby Park was expanded when the City closed sections of Parkview, Virginia and Edward avenues. In 1969, construction on the nearby Isabelle Park subdivision was in its final phase, and the City began negotiating with the construction company to ensure that an adequate storm drainage system would be installed at Tranby Park. Ultimately, the City and the construction company each paid half of the cost, an amicable financial arrangement which led to a much improved, and drier, Tranby Park. Later, a portion of Shiller's Bush was added to the land parcel through a subdivision development parkland dedication. Today, Tranby Park is equipped with softball diamonds, walking trails, a creative play unit and a small stormwater management pond.
