Across the street are the green offices of the Environmental Protection Agency. On top of the 8th floor is the first vegetated roof in Colorado. Multiple varieties of sedum plants were pre-planted in trays then installed on the terrace. The Alliance Center roof is the control site for a 10-year test of the effectiveness of EPA's green roof. Instruments on both roofs are measuring samples of storm water runoff and the filtering of pollutants.
