Multnomah County and the State of Oregon engaged Richard Zerbe and Associates though the University of Washington determined the ROI of the Raptor and Bridge Emergency Management Systems. The results found that both RAPTOR and Bridge appear to be efficient and highly beneficial investments. Utilizing a series of conservative assumptions, they found that the net benefits from the use of RAPTOR were at least $1,752,196 over the past year, for a benefit-cost ratio of 6.73:1. They also found that that the net benefits from the use of Bridge were at least $1,770,035 over the past year, for a benefit-cost ratio of 3.48:1.
