There are 48 known historic properties in the study area for Alternative 1, including the five existing rail stations. The study area for Alternative 2 includes 33 known historic properties. Impacts associated with these properties would depend on the need for acquisitions and future design. In general, historic properties adjacent to the existing, active UPRR alignment are not expected to be adversely affected, because the impacts to these historic properties, which are already adjacent to an active rail line, would likely be negligible.
