In 2009, the baseball/softball field was renovated and renamed the Randy Johnson Junior Giants Field after hometown boy Randy Johnson, a Hall of Famer and five-time winner of the Cy Young award for professional baseball pitchers.
The award-winning playground park was renovated in 2019 and features the May Nissen Swim Center, group picnic reservation areas, basketball courts, restroom building, horseshoe pits, multi-use sports field, tennis courts, pickleball courts, baseball/softball field, dog park, and a preschool.
