PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: This project will install a Stone Hoop native plant garden to serve as a bridge of learning between Native American cultures and park visitors. The selected site will encompass approximately 2000sqft of open ground near the entrance of the memorial. The garden construction will include site preparation, concrete flatwork for visitor access, a 4ft high natural stone retaining wall, and aluminum fencing. The selected contractor will be briefed on the design pertaining to Lakota star knowledge by the Mount Rushmore Cultural Resource Program

Manager. The design implementation will require imported compactable base material, excavation for the boulder retaining wall, final backfill, and subsurface drainage system for the new flatwork. The aluminum fencing will further organize the space and protect against falling per the Architectural Barriers Act standards. The accessible decorative concrete flat work and six inch raised curb to create the circular shape of the Stone Hoop will highlight the area and allow visitors to view up close a unique cultural feature.
