Kiwanis-Mary Hall Park was originally part of the 160 acres homesteaded in 1892 by William and Mary Hall. In 1952 9.7 acres was conveyed to the city with the stipulation that it only be used as a park. Downtown and Westside Kiwanis Clubs teamed up to complete the project; formed a committee in 1999. On September 16, 2002 then Mayor Jerry Munson signed an agreement to allow the park to proceed.
 
MILESTONES:

Work began in 2001. Volunteers hewed a nature trail along Lime Creek (the nature trail was upgraded in 2003 because of plant incursion.)

Spring 2003 - A native plant area was begun in an effort to enhance the numbers and kinds of native plants visitors could enjoy. The park currently has over 100 different native and introduced species.
 
Summer of 2003 - A learning platform with steps was installed leading down to Lime Creek and ground was broken on August 21, 2003, for Phase I, the shelter, of the Learning Center. Construction was completed in November, 2003 and the staining of the wood was completed in April, 2004.
 
Spring 2004 - Rapid City Fire Department personnel accomplished a controlled burn on the native plant area to remove dead vegetation and to help control the smooth brome grass; 150 native plants were transplanted, a sign and brochure box were added. Trenching and placement of sewer and water lines was completed.

Spring 2005 - Over 100 additional native plants were added to the native plant area. Oak and aspen trees were donated and planted by volunteers. West Middle School eighth grade science classes visited the park on several occasions. Their first visit in 2005 was to determine what projects they might accomplish and on the second visit they made a short path, and placed stones in Lime Creek for crossing.
 
Spring 2006 - Kiwanis-Mary Hall Park was honored by the Rapid City Urban Forestry Committee for the tree planting efforts in the park. West Middle School science class students helped clean up park areas, including Lime Creek, and later joined adult volunteers in planting nearly 200 shrubs and seedling trees. Plumbing the water into the shelter was completed in the summer of 2006, allowing volunteers to save approximately 90% of the transplants.
