with a baseline of the traffic volume in Year 2000 and projects Year 2030 traffic volumes based on certain growth projections, which assume that property in the region will gradually be developed according to the applicable General Plan designations, and that this development will add to the existing traffic volume. s The exact timing of the annual growth between Years 2000 and 2030 is not speciiied in the EVTM. Rather, it simply contains a starting count (2000) and an ending count (2030). Therefore, the SANBAG methodology requires the assumption of equal growth each year, which is calculated by dividing the total growth in traffic volume by 30, the total number of years in the study period ("Annual Growth").6 3) Third, the Annual Growth (determined in step two) for both 2008 and 2009 (326 ADT plus 326 ADT) is added to the baseline Year 2007 existing ADT volumes (determined in step one) to equal the Opening Year 2009 trafiic volumes without the Project. 4) Fourth, for purposes of calculating the Opening Year ADT only, the SANBAG methodology requires that regardless of what traffic growth actually occurs during Years 2000-2030, the assumption for any Opening Year's traffic count shall be no less than 10% above the last known existing traffic count for that roadway. The purpose of this requirement is to provide a conservative minimum growth rate for the calculation of Opening Year proj ect impacts. 'This test is not required for any subsequent year after the Opening Year, including the Year 2030 ADTs. 5) Fifth, the projected traffic volumes for the Project are added to the forecasted Opening Year ADT Without Project (the larger of the volume calculated in Step 3 and Step 4). The projected traffic volumes for the Project were calculated using the High-Cube Warehouse, Industrial Park and Truck Parking Facility trip generation rates and the square footage of each use set forth in Figure 1-3 of the EIR. As noted in Step 2 above, the EVTM already accounts for traffic generated by proposed and existing land uses in the San Bernardino County East Valley region. The Court raised a concern about calculating the traffic volumes in the region before the Project traffic volumes were added into the calculation. (Ruling, p. 9, footnote 2) However, this methodology is correct. The traffic generated by future High-Cube Warehouse, Industrial Park and Truck Parking Facility land uses (such as the Project) is already incorporated into the EVTM traffic volumes. However, to be conservative, Kunzman 5 Samples of the Year 2000 and Year 2030 EVTM plots describing total traffic volume at Agua Mansa Road immediately North of El Rivino Road are attached as Exhibit C(Year 2000) and Exhibit D(Year 2030). 6 For instance, the Year 2000 total eastbound and westbound traffic volume per the EVTM is 5,482 Average Daily Traffic ("ADT") (see Exhibit C), and the Year 2030 projected traffic volume per the EVTM is 15,266 ADT (see Exhibit D. The City assumed that traffic at that location increases by 326 ADT [(15,266 — 5,482)/30] in each of the thirty years between 2000 and 2030. wc-141612 g
