Our work to stabilize a section of Monument Creek near Mesa Road Bridge is complete and the new pedestrian ramp and underpass at the bridge is open to trail users.
Critical wastewater infrastructure that lies beneath the creek bed is now protected from potential exposure and damage and Pikes Peak Greenway Trail users have safer access to the creek channel. Project work required us to temporarily close a small section of the Greenway Trail near Mesa Road for construction vehicle access and to ensure public safety.
We continue to complete revegetation of the riparian area. We will monitor revegetated areas up to five years to ensure plant growth.
Project details
Degradation and erosion along the creek between Mesa Road and Bijou Street caused the channel to lower significantly over time, increasing risk to a large (42-inch) wastewater interceptor along the creek. We also needed to protect nearby non-potable and finished water mains.
Beginning in October 2023, the creek channel was raised in select locations along a 3,500-foot section and returned to pre-erosion levels. Work included the installation of boulder drop structures to control energy dissipation, and bank reinforcement.
With generous support from City Parks, Recreation and Cultural Services (PRCS) we also:
- Installed a pedestrian access ramp from the nearby trail to provide safe access to the channel corridor for recreational activities.
- Constructed an underpass at Mesa Road to improve safety.
The project prioritized preservation of historic components of the corridor, as well as minimizing the environmental impacts of our work. Of note:
- We worked collaboratively with PRCS to ensure State Historic Preservation Office requirements were met.
- We adhered to deed restrictions of Monument Valley Park.
- We added protections for a portion of the historic rockwork in the channel that was built under FDR’s Works Progress Administration to control flooding.
- FEMA regulations were followed to ensure the 100-year floodplain was not negatively impacted.
