Adams County Celebrates Major Milestone for Brantner Gulch Project

November 17th, 2025

On Monday, Nov. 17, Adams County Parks, Open Space & Cultural Arts marked a major milestone for the Brantner Gulch project by transitioning water flow into the new channel. These long-planned improvements, more than 20 years in the making, are necessary to protect natural resources, wildlife, and nearby residents and businesses.

The partnership with Mile High Flood District played a key role in advancing this work. The improvements are designed to reduce flood risk, protect property, and enhance stormwater quality. The project also enhances the natural character of the surrounding golf course and park and replaces an aging concrete channel with a more resilient and visually appealing system.

The previous concrete channel was undersized and failing, requiring significant annual repairs to keep it functioning. The Brantner Gulch project demonstrates the value of regional coordination through Adams County’s ongoing partnership with Mile High Flood District.

“Reaching this point in the Brantner Gulch project is a major accomplishment for our community,” said Lynn Baca, Chair of the Adams County Board of Commissioners. “By investing in this aging and undersized channel, we are protecting nearby homes and businesses while also restoring the natural character of the area. This project has been years in the making, and we are grateful for our partnership with Mile High Flood District and their commitment to improving safety and resilience for Adams County residents.”

With Brantner Gulch now flowing through its new channel, the project has reached 50% completion. Work will continue through summer 2026 to naturalize the area surrounding the new channel, create more spaces for enjoying nature, and improve access for pedestrians and emergency vehicles within Riverdale Regional Park, resulting in a safer and more resilient environment for the community.
