Associates added the calculated Project traffic to the EVTM traffic counts, <br />effectively counting the Project traffic twice. Additionally, 100% of the <br />Project traffic volumes are added to the traffic calculation beginning in the <br />Opening Year. However, it is anticipated that the Project will be built out <br />over several years, currently estimated to extend into Year 2011. <br />Therefore, assuming that 100% of the volume of the Project traffic will <br />begin in year one, rather than gradually increasing over several years, <br />represents a worst case scenario. <br />Calculation of Year 2030 ADT Volume: (See Exhibit B for a numerical <br />calculation of the steps described below.) <br />1-3) The first three steps for calculating Year 2030 ADTs are the same as those <br />above for calculating Opening Year ADTs. <br />4) This is not a required step for calculating Year 2030 estimated ADTs <br />because the 10% minimum increase only applies to the Opening Year <br />ADTs. <br />5) The fifth step for calculating Year 2030 ADTs is the same as step 5 above <br />for calculating Opening Year ADTs. <br />6) Sixth, Annual Growth is added per the EVTM to future years to arrive at <br />the projected Year 2030 ADT volume. <br />Exhibit B illustrates the methodology above using figures (both eastbound and <br />westbound) from Agua Mansa Road immediately north of El Rivino Rd. <br />In summary, the methodology used begins with existing traffic in 2007, adds <br />Annual Growth per the EVTM and finally adds Project traffic starting in Opening Year <br />2009. The combination of these three components results in the estimated 2030 traffic <br />volume. <br />3. SANBAG's Valley Signal Synchronization Program <br />SANBAG's Valley Signal Synchronization Program (also known as the SB <br />Valley Coordinated Traffic Signal System Plan) is a strategic plan for interconnecting <br />and coordinating traffic signals on major streets in the San Bernardino Valley area across <br />several jurisdictional boundaries. Four phases, or tiers, were recommended for <br />implementation of the program. Tiers 1 and 2 have been completed. Tiers 3 and 4 are <br />completely funded and scheduled. The funding source for Tiers 3 and 4 is the <br />Congestion Mitigation and Air Quality (CMAQ) funds.
