In 1984, the City of Boulder approved plans for a
continuous linear park that would span the city from its eastern fringe to
the base of the mountains, and Love & Associates, Inc. was retained to
contribute engineering and design services to this monumental team effort.
The Project was to provide an off-street transportation link to a variety
of city resources for bicyclists, walkers, runners, joggers and the
handicapped. In addition, the Corridor Project would preserve and enhance
fish and wildlife habitat in this urban setting, expand recreational use
of the creek.
Love & Associates worked very closely with the City of Boulder staff in
designing the world renown Boulder Creek trail system. Multiple
underpasses were designed in order to eliminate all at-grade crossings.
Complicated hydraulic design work had to be completed in order to
accommodate many of the crossings including maintaining the flood-carrying
capacity of the waterway and negotiations with and design for 12
irrigation companies who had two major dam structures on the creek. These
dams were removed while maintaining the water rights of the irrigation
companies. Additionally, an underpass at the Burlington-northern Railroad
was hydraulically modeled. The design was to provide for construction of
the box within a 12-hour window in order to maintain an open railroad
service. This was accomplished.
The Corridor Project timetable was originally 6 years at a projected cost
of $3.6 million for the basic path and waterway. The concept was expanded
to include a revitalization of the creekbed for fish and wildlife and
recreation, including two boat chutes and a system of drops and pools, yet
the project was completed in just three years at a cost of $3.3 million.
The Boulder Creek Corridor is a powerful example of teamwork in the
integration of engineering technology, environmental respect and attention
to human needs. |
