The third and final phase of the City of Longmont’s Spring Gulch #2 Greenway Project is now complete and the greenway is opened for pedestrian and recreational use. This greenway marks an important connection between Union Reservoir and Sandstone Ranch.

The entirety of this project took more than 10 years and $11 million to complete, with the flood in 2013 altering the design of the project to better help protect people, property and infrastructure from increased flood risk.

Spring Gulch #2 was created/completed in three phases:

• Phase 1 of the project was complete in 2013 and included a pedestrian underpass and box culvert under State Highway CO 119 as well as the construction of a sidewalk along the north side of the highway, extending from its intersection with 3rd Avenue east to Spring Gulch #2.
• Phase 2 was completed in the summer of 2021 and its work included the connection between Stephen Day Park and Union Reservoir. It also included the construction of the greenway trail and drainage improvements, installation of a 10-foot-wide concrete greenway, box culvert system that consisted of a pedestrian underpass, two drainage culverts and relocation of the Lower Oligarchy Ditch. Total construction cost of this phase was approximately $7.2 million.
• Phase 3, connecting the greenway trail segments of Phase 1 and Phase 2 between Union Reservoir and State Highway CO 119, is now complete. This section included stabilization of a stream bank that was severely eroded to improve drainage as well as the installation of a pedestrian underpass under the Great Western Railroad. The total construction cost of this phase was approximately $4.6 million.

As part of every City project, the importance of sustainability and environmentally responsible planning are at the forefront of design and implementation. The layout of the trail was sustainably designed to preserve existing native vegetation such as rabbitbrush that is an important flowering shrub for pollinators. In areas where vegetation disturbance could not be avoided, City staff seeded the areas with a diverse native prairie seed mix and further protected stream banks with native willows.

Residents who use the greenway over the next few weeks may still see some construction happening on adjacent to the trail. These are ongoing projects, but do not impact the use and availability of the trail. It is still safe to use.
