Edited sentence: Members of the public have criticized the at-grade crossings included in the Expo Line, claiming that these at-grade crossings carry with them risks and impacts to the community, especially at crossing near schools such as Dorsey High and Overland Ave Elementary.Metro expects to begin operations of Expo Phase 1 by the end of 2011 although funding deficits have raised questions about the completion date.Other objections are directed at the grade-crossing policy itself, saying that the thresholds for requiring grade-separation are not based on existing traffic conditions, and that the policy leads to results which unfairly impact low-income and minority communities.The Overland Ave crossing was deemed to not meet the criteria for grade separation based on the removal of available street parking and the addition of lanes of traffic instead of the current traffic conditions.The community has raised questions about the legitimacy of the criteria.The policy's primary criterion is impact on traffic while neglecting safety and environmental concerns.These objections are directed at at-grade crossings are inherently unsafe (especially near schools), and that they will cause traffic (based on the addition of lanes of traffic in order to meet the policy requirement to avoid costly at grade separation) and noise
