Lizard Rock Designs, LLC – Civil Design for New Armory Building

Civil design for 6-story senior housing downtown development

Prev Prev

As a subconsultant to Lizard Rock Designs, Cornerstone provided civil design for a six-story assisted living apartment building in Tucson, Arizona. Services included site grading and drainage, and utility work. This project required extensive coordination with other design team members (geotechnical, structural, hydrologists, architectural and landscaping), as well as coordination with other developers working in the immediate area.

The New Armory building will contain 143 modern 1-bedroom apartments for low income seniors, and is located in the Mission district, adjacent to the downtown area. This area is also in the heart of the Rio Nuevo District, an historic area being redeveloped as part of a major downtown revitalization project.

One of the major project design elements was preservation of an existing tree on the site. This tree, which grows adjacent to the proposed building footprint, next to the sidewalk, has been declared to be the largest tree in Tucson, and has been given the name of “Mel.”  Mel has a no-compaction zone designated around the trunk, which was addressed in Cornerstone’s grading design and had to be protected during construction.
