Rock Creek Erosion Control at Lake Link Trail

Broomfield has contracted with Civil Specialties, Inc. to construct the Lake Link Trail Erosion Control Improvements project.  The construction project will address existing erosion, and limit future erosion by adding an inlet and culvert under the trail, and installing a low tailwater basin, to prevent the Lake Link Trail from being undermined. The construction plans were developed in tandem with Boulder County’s Parks and Open Space Department which owns the property at the project location. Construction plans are also designed to minimize disturbance to the surrounding open space. 

Construction began in late October 2023. The trail closure is anticipated to last for approximately 8-12 weeks.  The intent is to complete the project and re-open the trail as quickly as possible. A detour will be provided for trail users during construction. Construction equipment will also be utilizing the Lake Link Trail to access the construction site.  Please use caution and share the trail when encountering construction vehicles.

Background

In 2005 Boulder County granted the City and County of Broomfield (CCOB) a Permanent Trail Easement for the construction of the Lake Link Trail on Boulder County’s Ruth Roberts Preserve.  The easement identified erosion of a drainage gulley near the SE corner of the parcel and required Broomfield to monitor the head cutting back toward the trail.  In recent years the erosion was identified as a threat to undermine the trail, if not mitigated. 

The City and County of Broomfield engaged Enginuity Engineering Solutions in 2022 to develop a solution and construction documents to address erosion threatening the Lake Link Trail.  Enginuity  surveyed and studied the area and developed a set of construction plans to address the existing erosion, add an inlet and culvert under the trail, and install a low tailwater basin, all in an effort to mitigate the current erosion, limit future erosion and prevent the Lake Link Trail from being undermined.  The construction plans were developed in close coordination with Boulder County’s Parks and Open Space Department, who manages the property, and CCOB’s Open Space and Trails Department.  An objective of the construction plans is to minimize disturbance to surrounding open space and limit trail closures.  Construction documents were approved and an invitation to bid on the construction was issued in August 2023.  Civil Specialties, Inc. was identified as the lowest qualified bidder.
