Denver Zoo sues over leaky, rusty $19 million new sea lion exhibit

Apr 2, 2026, 10:13 AM

If you pay $19 million for anything, it better be top-notch. Unfortunately for the Denver Zoo, their $19 million might’ve got them some shoddy work…

Less than a year after its celebrated opening, the Denver Zoo’s $19 million sea lion habitat is at the center of a lawsuit alleging the exhibit was poorly designed, shoddily built and now leaks.

The Denver Zoological Foundation filed suit in mid-March against Barker Rinker Seacat Architecture P.C. and Vertix Builders Inc., accusing both firms of multiple design and construction failures at the Schlessman Shores exhibit. The case was filed in Denver District Court under case number 26cv30952. 

The complaint alleges a litany of defects: active water seepage, cracked demonstration beaches, rusting doors and peeling paint — problems the zoo says inflated costs and undercut the original vision for the marquee attraction. The nearly two-year renovation was intended to give the zoo’s California sea lions a modern, immersive habitat and serve as a centerpiece of the facility’s ongoing capital improvement efforts.

Despite the legal battle, the Denver Zoo Conservation Alliance told Denver Westword that the sea lions at Schlessman Shores are “safe and healthy” and that “there are no immediate health or safety concerns for the animals.” The zoo said some of the issues cited in the lawsuit have already been addressed and that it is committed to resolving the remaining problems to protect the long-term sustainability of the habitat.

Schlessman Shores remains open to the public, and daily sea lion demonstrations are still being held on schedule, according to the zoo.
