Based on 2035 transportation emission rates. ' For purposes of this GHG analysis, buildings on proposed land uses are assumed to comply with the 2013 Building and Energy Efficiency Standards, which are 25 and 30 percent more energy efficient for residential and nonresidential buildings, respectively, than the 2008 standards. This analysis assumes new buildings of all land use types exceed the 2008 standards by 25 percent. Includes water efficiency improvements required under CALGreen. 2 For the purposes of this GHG analysis, existing buildings are assumed to achieve the 2005 Building and Energy Efficiency Standards. However, it is likely, that based on the existing housing stock many of the units were constructed prior to the modem building and energy efficiency standards and are therefore even less efficient. 3 Service population based on: Existing - 3,252 residents and 1,386 employees within the Harbor Boulevard Mixed Use Transit Corridor Plan boundaries. Future - 18,579 residents and 1,559 employees within the Harbor Boulevard Mixed Use Transit Condor Plan boundaries. As shown in this table, the net increase in GHG emissions of 43,747 MTCO2e from Project related operational activities would exceed SCAQMD's draft bright line screening threshold of 3,000 MTCO2e for all land use types. The increase in residential and retail land uses within the specific plan boundary is the main factor for the increase in overall GHG emissions. Since the draft bright line screening threshold would be exceeded, a detailed emissions analysis of the project's efficiency compared to the draft SCAQMD GHG per capita threshold is included. The project's efficiency is determined from the total emissions divided by the project's service population, which is the number of people who live or work within the specific plan area. At buildout, the project would generate approximately 74,115 MTCO2C of GHG per year and exceed the SCAQMD draft bright line screening threshold of 3,000 MTCO2e. However, buildout of the proposed project would decrease the per capita GHG emissions within the specific plan area to 3.68 MTCO2e per service population (employees and residents), which would be below the SCAQMD efficiency standard of 4.8 MTCO2e per service population. Although implementation of the proposed project would increase overall emissions, it would also increase the land use intensity along the Harbor Boulevard corridor resulting in a reduction of per capita emissions. The corridor is currently served by public transit bus lines, and there are plans within the coming decade for the establishment of a bus rapid transit route and stops along the section of the corridor within the proposed project plan area (see Impact 5.5 -2 discussion). In addition, development of residential and nonresidential land uses in proximity to each other along with the public transportation options would likely reduce VM'17. Furthermore, construction of new structures would introduce buildings Page 5.5 -14 PlaceWorkr
