In 2018, Designs By Sundown was honored to partner with GE Johnson Construction on a project at one of the most prestigious zoological institutions in the country: Cheyenne Mountain Zoo. Known for its conservation efforts and immersive exhibits, the Zoo consistently ranks among the top in the nation. So when we were asked to help rebuild part of the hippo enclosure, we knew this was a big deal.
The scope included reconstructing a retaining wall between the hippo and penguin habitats and making improvements to the suspension bridge that gives visitors an elevated view of the animals. The vision was ambitious — to create a South African beach-inspired replica of the Nile River right in Colorado.
This project came with unique challenges. Working inside a functioning zoo required extraordinary precautions beyond standard safety protocols. Each morning began with team safety meetings, PPE checks, and even group stretches. Materials underwent dual inspections — first for quality and then for “Hippo Safety,” ensuring rocks were smooth, stable, and non-toxic. Deliveries had to occur after hours due to visitor traffic, and once inside, every load was escorted by flaggers to maintain safety throughout the grounds. Work schedules were carefully coordinated around hippo feeding and recreation times.
From the Zoo’s perspective, this wasn’t just an aesthetic upgrade. The new exhibit was designed to improve sustainability with a state-of-the-art filtration system that reduces water use and lowers the Zoo’s carbon footprint. The space would house the Zoo’s two Nile hippos, Zambezi and Kasai, with room for up to five hippos total. Plans even included welcoming a male hippo in hopes of future babies. During construction, Zambezi and Kasai were sent on “vacation” to Dickerson Park Zoo in Missouri, ensuring their comfort and safety while the transformation took place.
For our team, this was one of the most technically challenging and rewarding projects we’ve ever completed — blending creativity, precision, and a deep respect for wildlife and conservation.
