Greeley Salt Lake and Pacific Railroad Grade

Year Listed: 2009
County: Larimer County
Construction Date: 1881
Threat When Listed: Development
Status: SAVE

This National Register listed linear landscape is associated with early efforts to connect northern Colorado with the transcontinental railroad. Also significant is this site’s involvement with regional, commercial, and industrial development, as this line transported locally quarried sandstone used on many buildings throughout Northeastern Colorado. The railroad also transported limestone to eastern plains sugar beet factories. With its construction in 1881 and its eventual abandonment in 1988, this section of rail line represents more than 100 years of railroad history. Uniquely, this is one of the few abandoned rail lines in Colorado that retains its historic alignment, railroad bed, ballast, ties and rails. Included are three historic bridges, one of which is a turntable that was manufactured in Chicago in 1892 and originally used in Wyoming until it was installed over the New Mercer Ditch in 1926.

The threat to the site is that the City of Greeley has not increased their water carrying capacity in over 50 years and a pipeline is important for the continued growth of Greeley. The City intends to entrench a 5-foot-diameter water pipeline 10-foot deep along the route of the Greeley Salt Lake and Pacific Railroad line. Construction would effectively destroy this historic resource. While other potential routes exist, they have been deemed too expensive or too disruptive.

The City of Greeley is continuing with plans to install the pipeline in the Grade’s right of way. A recent settlement between the City and landowners will allow limited archaeological and biological surveying of the site, though a coalition of citizens, land owners, and preservation groups – including Colorado Preservation, Inc.– continue to lobby for the use of an alternative route that would preserve the Greeley Salt Lake and Pacific Railroad Grade.

The pipeline project is complete and was routed under one section of the railroad grade and buried. Site monitoring is ongoing by local property owners. Federal mandate required Greeley to respect historic structures and minimize environmental impact. Land was surveyed to assess what crews need to avoid or mitigate. The site needs continued monitoring to the disturbance of historic resources.

Preservation for a Changing Colorado

The 2017 update, Preservation for a Changing Colorado, resulted from a partnership between Colorado Preservation and History Colorado and Colorado Preservation, Inc. Prepared by Clarion Associates, the new report and accompanying website document the economic benefits of rehabilitation projects, analyzes property values and neighborhood stability in local historic districts, and summarizes the increasing impact of heritage tourism, private preservation development and the success of Colorado’s Main Street program. In a key finding, researchers found that for every $1 million spent on historic preservation in Colorado leads to $1.03 million in additional spending, 14 new jobs, and $636,700 in increased household incomes across the state! The 2017 report also considers the important role preservation plays in helping Coloradans provide new spaces for creative communities and co-working, create and sustain meaningful places, respond to the state’s changing demographics, and address climate concerns.
