McKay Dee Hospital



  • 1900 trees were planted.
  • 4.2 acres of land with trees were saved along the perimeter of the site.
  • A pre-design soil assessment was conducted, allowing healthy soils to be conserved and others to be amended.
  • Wetland plants were planted along the lake’s edge, offering root stability to prevent erosion control and habitat creation.
  • Plants are allowed to go to seed/flower life. Prairie grass and wildflower mixes were specified.
  • The project avoids annual planting.


  • Trees have the potential for intercepting 950,000 gallons of water which equal the water usage for 9,500 American residents for one day. This is also the equivalent amount of water for 1.4 Olympic-sized swimming pools.*
  • The site design mitigates runoff with drainage swales located on the west side of the project.


  • The trees sequester 228,000 pounds of carbon annually, which offset 27.4 cars per year.**
  • The project uses regional materials.
  • A water feature was introduced to reduce temperatures.
  • The planting strategy reduces temperatures in urban areas.
  • During construction, pollutants were controlled and retained.
  • Exposure to environmental tobacco smoke was minimized through designated smoke-free zones and prohibited smoking on-site.


  • The property value of a home adjacent to the site has doubled since 2000.
  • Posts on social media brag about the quality of the outdoor environment, stating, "Took a stroll around the pond at lunch today. Pretty sure my workplace is prettier than yours" or "Behind me was this amazing fountain and a park and everything. It was made so you can chill and visit it."

* The tree average for water interception is 500 gallons. American’s use an average of 100 gallons of water per day (EPA’s water trivia facts) Colloquial volume of an Olympic pool is 660,000 US gallons assuming the depth of 2m.

**120 pounds of CO2 per tree annually (This number is based on an average from the National Tree Benefits Calculator) One car produces an average of 8,320 pounds of CO2 per year. (The Code of Federal Regulations - 40 CFR 600.113)

McKay Dee Hospital

McKay-Dee Hospital selected this 63-acre site for expansion and ultimate relocation of its regional facility. Surrounded by rolling topography and lush vegetation, this former agricultural site is ideal for a new healing environment. 

In order to provide patients with the best views from their recovery rooms, the hospital was situated on the higher end of the site where the blue and green peaks of the nearby Wasatch Mountains are seen in the distance. Adjacent to the bedroom tower is a serpentine pond, a dining terrace, and a series of inviting courtyards, all linked by a winding path. A semicircular arbor frames one side of the dining terrace, inviting patients, staff, and visitors to relax in the shade and enjoy the views of the pond with its mountainous backdrop.
