The century-old concrete silos topped with Rio Grande Co. signage along Santa Fe Drive could be coming down.

The building materials company, which owns the site and still operates there, has applied for a demolition permit for the structure, which is set back from the road at 123 Santa Fe Drive in the Baker neighborhood, next to a light-rail line.

In early March, city landmark preservation staff — which reviews all total demolition permit applications — determined that the site had the potential for historic designation. Laura Swartz, spokeswoman for Denver’s Community Planning and Development Department, said the finding kicked off a three-week period during which notice was posted at the site and various community organizations were contacted so that any interested parties could submit a landmark preservation application, which could halt demolition.

Swartz said Friday, two days after the end of the three-week period, that no one had submitted a preservation application for the silos.

The landmark review process is just one component of the demolition permit application process, and Rio Grande needs to receive additional approvals before a demolition permit is issued for the silo site.

Rio Grande President Dave Wenman did not return a Friday voicemail. Alpine Demolition would perform the work, according to the permit application.

Swedish immigrant Elmer J. Peterson established the Rio Grande Fuel & Feed Co. in 1908, and the company remains in the family. According to a report by city staff, the silos were constructed between 1915 and 1925, and used to store coal. When natural gas heating replaced coal heating in the mid-1900s, the company shifted its focus to supplying construction materials, such as cement, sand and gravel.

“Due to their height and uniqueness, the silos have become a visually orienting feature within the Baker neighborhood,” city staff wrote in the report.

Other properties currently facing demolition for which the city has found the potential for historic designation are the medical office building at 7060 E. Hampden Ave. (where a new medical building is planned) and the home at 400 S. Monaco St. Pkwy, once part of the homestead of a Colorado Supreme Court justice. Those properties are in the midst of their three-week posting period.

One of the more prominent structures recently demolished in Denver was the research bridge over 9th Avenue that was part of the University of Colorado’s Health Sciences Center. Additionally, a five-story office building in the Golden Triangle is being demolished.
