Montana Eye Care

Project Description

Working with Mosaic Architecture, the project included design and construction of a new 12,000 square foot clinic building. The new facility, located at the intersection of Montana Avenue and 11th Avenue in Helena, houses both an optometry clinic and retail showroom.
Site design included challenges associated with keeping the existing clinic building in service, while the new facility was being constructed. In addition to a fully accessible site design, the new facility includes 10,000 gallons of underground stormwater detention/retention, located directly underneath the new 38-stall paved parking lot. The underground facility is constructed of aluminized corrugated steel piping, with perforations to allow stormwater runoff to infiltrate on-site.

KEY PROJECT ELEMENTS

  • New 38-Stall Paved Parking Lot
  • Underground Stormwater Detention/Retention System
  • ADA Accessible Site Design
  • Site Landscaping and Privacy Fencing

Central Elementary School

Project Description

As a subconsultant to SMA Architects, RPA provided civil, site and landscape design services for the new Central Elementary School in Helena, Montana. The site posed significant grading challenges, due to an elevation change of nearly 30 feet across the 3-acre site. The design team incorporated site walls and variable building finished floor elevations to ensure usable and accessible exterior spaces. Construction of the new school was completed in August 2019, in time for the 2019- 2020 school year.
