2015 List – Colorado’s Most Endangered Places


The 2015 sites have been selected and officially announced!  

Colorado Preservation Inc’s Most Endangered Places for 2015 are……

2015 sites

Four diverse sites were selected in 2015 that speak to Colorado’s evolution and development.  The sites include one of Denver’s early streetcars, a cultural landscape tied to the orchard industry, one of the most intact gold dredges in the state (and possibly the nation), and one of Colorado’s largest producing lead & silver mines.

Colorado Preservation, Inc. through its Endangered Places Program devotes staff time and resources to raise funds and rally concerned citizens so that listed, as well as non-listed, sites can be saved. We are proud to be able to work within communities as issues and threats arise in order to advocate for preservation throughout the state.

Preservation for a Changing Colorado

Historic preservation has a direct economic benefit to communities and Colorado! Take a look at the 2017 study, which considered the ways adaption of historic places has a direct financial effect on the state.

This updated, most resent study, was the result of a partnership between Colorado Preservation, Inc and History Colorado, funded by a grant from History Colorado's State Historical Fund. Prepared by Clarion Associates, the new report 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 determined that for every $1 million spent on historic preservation in Colorado it produced $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, responds to the state’s changing demographics, and addresses climate concerns.
