Bielins Hock Stream Restoration Project
Boulder County Parks & Open Space is implementing the restoration of 850 linear feet of Left Hand Creek on the Bielins-Hock Open Space Property from damage that occurred during the flood of September 2013.
Construction is expected to be completed by September 30, 2017. The LoBo Trail will not be closed during construction, however there may be short waiting periods to continue on the trail past the project site. Flaggers will be on the trail when large trucks are entering the trail corridor.
This project is supported by grants from United States Department of Agriculture, Natural Resource Conservation Service, Emergency Watershed Protection program and administered through the Colorado Water Conservation Board’s Colorado Watershed Program and State of Colorado funds provided from the State Disaster Emergency Fund with matching funds from Boulder County.
