The Swaner Nature Preserve is a 1,200-acre non-profit land trust located in the Snyderville Basin of Utah. The preserve features a 10,000 SF state-of-the-art visitors’ educational center.

As a part of a team, Psomas provided civil engineering and land surveying services for all site improvements including grading, drainage and utility plans. A pervious concrete design to manage the stormwater runoff was developed, a year-round rooftop water collection and storage system was incorporated into the design, and assistance was provided throughout the documentation process for the building’s LEED® Platinum Certification.

Because all stormwater had to be retained on-site, Psomas produced an erosion control plan to ensure the sensitive wetland area was preserved in its natural state throughout the construction process.

In a further effort to harvest all stormwater on-site, Psomas developed a system that collected rainwater runoff from the rooftop in an underground cistern for use in the building’s toilets and irrigation systems. Consequently, the building requires zero domestic water for sewage conveyance and irrigation.
