currently leave Pleasanton for such services will instead switch to using the local services instead. According to the Market Assessment, only 20 percent of the grocery sales and 55 percent of restaurant sales are assumed to be new. The remainder of the sales are projected to shift from the existing market base. I.e. these would not generate new trips, but represent existing trips that would be shortened. Trip generation rates have accordingly been reduced for these uses. Baseline: Previously Approved Office Only Protect In 1999, the City of Pleasanton certified an EIR for the Bernal Property Specific Plan, which includes the subject site. That 1999 EIR 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, if such analysis had been conducted for the approved Office Only Project using the current methodologies, the results would have been as shown in Table 1. TABLE 1: OFFICE ONLY PROJECT GHG EMISSIONS, BASELINE Emission Source Vehicle Miles GHG Emissions Traveled 1 ' (CO2e metric tons per year) Transportation 138,293 20,822.52 Area Source 0.45 Electricity _ 6,404.53 Natural Gas 1,043.84 Water and Wastewater 100.13 Solid Waste 5,187.33 Refrigerants 0 Baseline Emissions 33,558.81 1. Vehicle Miles Traveled presented in this table include no adjustment for pass -by trips. 2. Per the Trip Length Analysis, the following trip lengths and speeds were assumed for office uses: commute =24.4 miles at an average speed of 45 miles per hour, non - commute=9.9 miles at an average speed of 35 miles per hour. The emission of 33,558.81 metric tons per year of CO2e represents the baseline emissions that can be assumed would have been generated from the previously approved Office Only Project. Change to the Proposed Retail and Office Project The proposed change in land use from office only use to a mix of retail and office uses has substantially changed traffic generation and vehicle trip characteristics at the site. Generally, retail uses generate a greater volume of trips than do office uses, but these trips tend to be much shorter in distance. Whereas, if the site was developed as office, the office commute trip would be 24.4 miles, if it was instead developed as retail, a typical retail customer would travel only 4.6 miles. Retail uses also generally have lower utility usage than office, which factor in to the total GHG emissions. Therefore, while retail uses generate a greater number of overall trips, the increase in GHG emissions associated with such uses is not as great, as shown in Table 2.
