Greenhouse Gas Emissions The impact threshold for Greenhouse Gas (GHG) emissions is 1,000 metric tons per year. Exhibit L is the GHG analysis for the proposed development. The project's GHG emissions were analyzed using the Bay Area Air Quality Management District's URBEMIS 2007 model and the BAAQMD GHG model for total carbon dioxide equivalent (CO emissions from transportation, electricity use, waste, and refrigerants, etc. Default model settings were used except for trip generation, pass -by trips (traffic already using the adjacent roadway), and diverted -link trips (when a diversion is made from the regular route to make an interim stop) from the Traffic Impact Study completed for this project. The GHG emission analysis also accounted for the market shift that is anticipated to occur for the proposed grocery store and restaurants whereby some residents who currently leave Pleasanton for such services will switch to using the services available at Pleasanton Gateway instead, resulting in fewer total vehicle miles traveled. By shopping at the project, some patrons will actually drive less than they would have otherwise, so no additional vehicle miles traveled were added to the GHG models for these trips. The Final EIR for the Bernal Property Specific Plan includes the Pleasanton Gateway site, but did not contain an analysis of GHG emissions, as there were no state guidelines, applicable air district thresholds or other such requirements in effect at the time. However, to establish the baseline for the Gateway property with the vested office entitlement, the GHG emissions for the 745,000 square -foot office project were modeled using the BGM and URBEMIS models and then compared to the proposed development. The results of the analysis are summarized in Table 4, below. Table 3: GHG Emissions of the Approved Office Project and the Proposed Retail /Office Project (CO metric tons per year).

The proposed change in land use from an office only development to a mix of retail uses and office uses catered to nearby neighborhoods and employment centers will substantially change the traffic generation and vehicle trip characteristics at the site. Generally, retail uses — supermarkets especially for the p.m. commute — will generate a greater volume of trips than office uses, but these trips tend to be much shorter in distance. Therefore, changing the previously approved office only project to the proposed Pleasanton Gateway Page 29 of 35 August 25, 2010
