Hidden Hollow Natural Area Waterwise Enhancements

Hidden Hollow Natural Area Waterwise Enhancements

This project replaces the existing irrigation system in Hidden Hollow to support vegetation, tree and lawn health. It will also repair wooden stairs leading to a stream-side boardwalk, and improve the events amphitheater. 



Implementation and Construction beginning Spring 2023

Full Project Scope

This project will include replacing a failing irrigation system in Hidden Hollow to support central lawn areas, native planting beds, tree plantings, and habitat demonstration areas, and replace native turf and shrubs killed from lack of water, and will remove a few invasive tree species creating unsafe conditions in the park. The project will also complete the trail lighting project started in 2016, by installing remaining light bollards on south trail alignment. The power hookup to amphitheater for Hidden Hollow concerts and events will be replaced, and damaged stone monuments and plaques will be evaluated. Stairs to the boardwalk on the north side of the stream will be replaced as well.


Public Lands is working to address the aging irrigation system to support native vegetation, tree and lawn health in Hidden Hollow, and to improve the functionality and aesthetic of the amphitheater space.

The project is anticipated to substantially improve the aesthetic appearance of this natural area, improving public perception of stewardship and safety, which in turn is projected to increase public use and appreciation of this special place.

Hidden Hollow was established and protected in perpetuity as a wild open space area, per the terms of the conservation easement on the property held by Utah Open Lands, and the Hidden Hollow Master Plan and related improvements.

Hidden Hollow’s original irrigation system is reaching the end of its functional life; frequent irrigation line breaks and failing parts now make it virtually impossible to adequately water the central meadows and native planting areas, even while excess water is wasted. Many other improvements, including signage, benches, and other features are aging and damaged or missing. Lighting on the trail system was partially completed in 2016, but additional funds are required to complete the path lighting.

Overall, this project is necessary to give Hidden Hollow a much-needed face lift and facilitate the continuation of waterwise native planting areas and natural landscaping that was initially envisioned.
