Allina Health is one of the leading regional healthcare providers, drawing patients and visitors from throughout Minnesota and nationally. Abbott Northwestern Hospital’s (ANWH) 10-year Facility Master Plan created a framework to support the anticipated growth of the hospital campus which will allow the hospital to continue providing world-class services to the region. A critical goal of the master plan was to increase parking capacity at the campus to allow for future growth.

Allina Health’s mobility plan prioritized the reduction of single-occupancy vehicles on the ANWH campus, spurring the need for holistic parking and multimodal transportation solutions that integrate into the wider Minneapolis transportation network. Allina understood that the Purple Ramp could be transformative for the campus and the broader community. This project provides a horizontal and vertical expansion of the existing parking ramp at the south end of the hospital campus and accommodates multiple transportation modes including cars, bicycles, pedestrians, and transit—and offers connections to the Midtown Greenway, a heavily used and highly prized bicycle and pedestrian tail along a 5.5-mile former railroad corridor. The Purple Ramp also provides a welcoming “front door” to the ANWH campus with an activated streetscape designed to enhance the visitor experience.

Kimley-Horn led the design of the new Purple Ramp, providing project management, entitlement, structural engineering, parking consulting, civil engineering, landscape architecture, and traffic engineering services. The Purple Ramp consists of an eight-level parking structure (approximately 1,425 parking stalls), approximately 2,000 square feet of retail/office space, and a two-level vertical expansion of existing Ramp 6 (approximately 425 parking stalls). This parking ramp provides parking for patients and employees and includes a storage facility for approximately 200 bicycles. Allina Health also proved their commitment to the neighborhood and the environment by incorporating the following sustainability features:

  • Community Solar Garden. The Purple Ramp community solar garden will generate approximately 1 megawatt of electricity—enough energy to power 250 homes.
  • Community Promenade. Along the Midtown Greenway, a sidewalk promenade connects Chicago Avenue and Elliot Avenue. This previously unused space creates a more vibrant streetscape and native plants that will attract pollinators and help manage stormwater.
  • Electric Vehicle Charging Stations. Allina Health is providing 20 electric vehicle charging stalls in the Purple Ramp which was designed to be expanded in the future.

“Kimley-Horn was a new design partner selected by Allina Health to lead the design of one of our largest parking structures, the Purple Ramp at the Abbott Northwestern Hospital Campus. Kimley-Horn was selected based on their experience, technical abilities, team approach, city entitlement experience, and financial stewardship. They did not disappoint.

The Kimley-Horn team’s ability to lead a collaborative design process with Allina Health and other stakeholders, including governing agencies, the general contractor, and the community, was impressive and professional. Allina Health felt well represented with Kimley-Horn taking the lead in the City of Minneapolis entitlement, planning and permitting process, which resulted in successful outcomes for Allina Health.

Kimley-Horn laid a solid foundation from which to build Allina Health’s expansion of the Abbott Northwestern Hospital campus, and have secured a long-term partnership for Allina Health.”

Noteworthy Features

  • Activated Chicago Avenue tenant space.
  • Connections to Midtown Greenway to reduce single-occupant vehicle trips.
  • Plantings that attract pollinators.
  • Enhanced space-by-space parking guidance system.
  • Improved loading dock area on the ground level of the parking ramp.
  • Rooftop solar installation that transfers energy back to the grid.
  • Architectural façade on the entire building complements the surrounding area.
  • Enhanced pedestrian experience through streetscape elements and connections to transit and bicycle/pedestrian facilities.
  • Relocated oxygen tanks and screened the view, while maintaining critical hospital services.

Kimley-Horn leveraged experience and longstanding relationships with the City of Minneapolis and the other project stakeholders to lead this project through the entitlement and neighborhood engagement process in a way that provided meaningful involvement by the community while prioritizing the interests of ANWH.
