Environmental Checklist <br />For CEQA Compliance <br />2010, (2) 1990 levels by the 2020, and (3) 80% below the 1990 levels by the year 2050. In <br />2006, this goal was further reinforced with the passage of Assembly Bill 32 (AB 32), the <br />Global Warming Solutions Act of 2006. AB 32 sets the same overall GHG emissions <br />reduction goals while further mandating that ARB create a plan, which includes market <br />mechanisms, and implement rules to achieve "real, quantifiable, cost-effective reductions of <br />greenhouse gases." Executive Order S-20-06 further directs state agencies to begin <br />implementing AB 32, including the recommendations made by the state's Climate Action <br />Team. <br />Climate change and GHG reduction is also a concern at the federal level; however, at this <br />time, no legislation or regulations have been enacted specifically addressing GHG emissions <br />reductions and climate change. According to the IPCC report, Climate Change 2007: The <br />Physical Science Basis: Summary for Policymakers (February 2007), there is no doubt that <br />the climate system is warming. Global average air and ocean temperatures as well as global <br />average sea level are rising. Of the last 12 years, 11 years have ranked as among the <br />warmest on record since 1850. While some of the increase is explained by natural <br />occurrences, the 2007 report asserts that the increase in temperature is very likely (> 90%) <br />due to human activity, most notably the burning of fossil fuels. <br />For California, similar effects are described in the California Climate Change Center report, <br />Our Changing Climate: Assessing the Risks to California (July 2006). Based on projections <br />using state of the art climate modeling, the temperatures in California are expected to rise <br />between 3° F and 10.5° F (1.7° C and 5.8 ° C) by the end of the century dependent on how <br />much California is able to reduce its GHG emissions. The report states that these <br />temperature increases will negatively impact public health, water supply, agriculture, plant <br />and animal species, and the coastline. <br />Impacts <br />Automobiles have been identified as the greatest source of greenhouse gas emissions, and <br />the quantity of GHG emissions from automobiles is directly correlated with the amount of <br />vehicle miles traveled (VMT). The SCAQMD is in the process of releasing an updated <br />version of the URBEMIS 2002 emissions estimation/evaluation model that will calculate the <br />impacts associated with greenhouse gas emissions, especially carbon dioxide emissions <br />from mobile sources. Because automobiles are the largest contributor to COz emissions, it <br />can be deduced that if a project does not result in an increase of daily trips or VMT, that the <br />project would not result in an increase of GHG emissions. As discussed in Response XV-A. <br />under Transportation/Traffic, the proposed project would result in a net decrease of 6 daily <br />trips, 20 AM peak hour trips, and 13 PM peak hour trips. This net decrease in trips results in <br />a net decrease of VMT, and ultimately in a net decrease of GHG emissions. Consequently, <br />there would be an overall net beneficial impact to GHG emissions. <br />IV. Biological Resources <br />A. No Impact. The project site is located in a fully urbanized setting and is void of any native <br />• vegetation or wildlife habitat; therefore, it does not have the potential to accommodate <br />sensitive biological resources. No impacts would occur. <br />B. No Impact. The site is void of any riparian habitat or other natural communities; therefore, it <br />does not have the potential to accommodate sensitive biological resources. No impacts <br />would occur. <br />Alton Court August 200 <br />Initial Study/Mitigated Negative Declaration 3-20 <br />gas oosss.o~ <br />75A-86 <br />
