Denver Central Platte Campus


1271 and 1241 West Bayaud Street, Denver, Colorado

The Bayaud Street site had a long history of economic production dating back over a hundred years to the time that Denver's economy was dominated by mining and mineral processing. But for the owner, General Chemical, the facilities were old, expensive to maintain, and no longer optimally located.

1. Please provide a brief overview of the project.

Goal of the project.
This project achieved multiple goals including:
  • revitalization of a historical brownfield,
  • modernization of facilities for a chemical manufacturer and the City and County of Denver (Denver), and
  • realization of the economic and social benefits of a new light rail system.

The Bayaud Street site had a long history of economic production dating back over a hundred years to the time that Denver's economy was dominated by mining and mineral processing. But for the owner, General Chemical, the facilities were old, expensive to maintain, and no longer optimally located. General Chemical was looking to sell the property and build a new facility. For Denver, the site was strategically located adjacent to the iconic Art Deco city waste water building and a perfect site to centrally locate key municipal services. Denver needed such a property because the expansion of the regional light rail system required the acquisition of a Denver property that was being used for maintenance operations. A major sticking point quickly emerged between Denver and General Chemical when Denver could not indemnify General Chemical from environmental liability associated with the site's contamination. International Risk Group, LLC (IRG) was able to provide a solution - they would acquire the site, integrate the cleanup with the site preparation, and sell the property ready for development to Denver and do so within the very tight time schedule. The innovative approach taken on this project enabled Denver to acquire the property despite significant issues due to environmental indemnities. Denver, through their public-private partnership with the IRG, was able to integrate a significant environmental cleanup with the site preparation and construction of their new facilities, was able to use environmental insurance to back the indemnities needed for the transaction, and was able to revitalize a catalytic brownfield property that is yielding benefits to surrounding properties. Denver was able to vacate and transfer properties in a timely fashion to the regional transportation effort. Denver was able to construct their new facilities in a compressed time frame and was able to meet schedule constraints presented by the complexities of this project. General Chemical also achieved their goal of modernization through the construction and opening of a new, more efficient manufacturing facility on another property in an industrial area of the city.

Location of the site.
The site is located in Denver, Colorado (1271 and 1241 West Bayaud Street), adjacent to the South Platte River and Interstate 25, approximately two miles from downtown Denver. Approximate size of the site (in acres): 37 acres.

Former use of the site.
Starting in the 1880's and continuing through 2008, the property was heavily used for the roasting of mineral ores, the production of acids, and the manufacturing of various chemicals. Much of the property contained fill materials from the beneficiation of mineral ore, and a large area of the site was used for historical disposal of roaster ash, slag, and materials associated with demolition of process plants throughout the history of the facility.

Actual end use of the site.
The end use includes public works offices, a public works maintenance facility, storage for snow plows and other equipment, a centralized fueling facility for the city maintenance fleet, an animal shelter, and storage facilities for road salt and road de-icing chemicals. These facilities cover the majority of the 37 acres with buildings, roadways, or asphalt parking lots, helping to form a protective cap on the site. The facilities are fully integrated into and part of the environmental remedy. They, along with a 2-foot thick soil cap within the unpaved portions of the site, effectively form a barrier to exposure to subsurface materials, prevent direct human contact with contaminated soil, and prevent infiltration that would come into contact with waste and ultimately impact groundwater at the site.

Date the project was complete.
Most of the facilities were opened in 2009 and 2010, and the final facility, the Animal shelter, was completed and opened in June 2011.
