Work In Progress
The contractor is starting upstream at the South St. Vrain Road bridge and working downstream; weather permitting.
Primary activity this week is grading and excavation; excess material is being hauled off-site for screening, reuse and disposal
1. Erosion control BMPs installed.
2. Continue downstream bench and overflow channel cut.
3. Continue to haul excess material.
4. Continue to screen material for usable boulders and cobbles for rock
features.
5. Large cottonwood across channel at Station 11+20 removed.
6. The stream bank at the Labyrinth will be reinforced with boulders and vegetation to provide improved flood resiliency. Additionally, two sets of sandstone steps will be added to provide safe and convenient access between the Labyrinth and the stream.

Preliminary steps for the South St. Vrain Creek Restoration Project, Reach 4b, Site 3 (SSV4b-3 or SSV3) are underway. Upon receiving final permits, hard construction will begin. Like previous stream restoration work, this project will improve stream health and increase flood resiliency, resulting in lowered risk to adjacent properties.
While the final outcomes are vast improvements to the creek and adjacent properties, the construction process unavoidably increases turbidity in the channel for the short duration of construction, meaning we will create “muddy water”. Or in other words, it looks worse before it gets better.
The construction contractor, Naranjo Civil Constructors, is a leader in reducing temporary impacts during river work. The team has employed continuous video recording along the reach of the project, to be used for real-time observance and time-lapse progress footage, among other applications.
