EXHIBIT 2 <br /> �OAA Santa Ana Boulevarei <br /> A <br /> /�iZ M Grade Separation Proje <br /> Therefore, under each phase of construction, four travel lanes will be maintained (two on <br /> Santa Ana Boulevard, and two on Fruit Street). Figures of both phases of construction, <br /> showing the proposed detour configurations are provided in Appendix J. <br /> The existing ADT reported in the Transit Zoning Code EIR Traffic Study for this segment <br /> was grown by 0.5 percent per year to estimate Opening Year (2016) ADT. Per the City's <br /> significance criteria, roadway segments are compared to LOS E capacities reflected in the <br /> General Plan Circulation Element. Table 11-1 summarizes the results of the roadway <br /> segment analysis. <br /> Table 11-1 Santa Ana Boulevard Roadway Segment Analysis <br /> Opening Year #of LOS E <br /> Roadway From To (2016) ADT' Lanes Capacity2 LOSS <br /> Opening Year(2016) <br /> Santa Ana Blvd Santiago St 1-5 Freeway 20,093 6 56,300 A <br /> Opening Year(2016) during Construction (reduction of two travel lanes) <br /> Santa Ana Blvd Santiago St 1-5 Freeway 20,093 4 37,500 A <br /> Notes: <br /> Opening Year ADT referenced from existing ADT from Transit Zoning Code EIR Traffic Study,grown to year 2016 <br /> 2 LOS E Capacity referenced from City of Santa Ana General Plan Circulation Element <br /> 3 LOS determined by assigning a letter grade based on the numerical value of the volume-to-capacity ratio. <br /> As shown in Table 11-1, a reduction from six lanes to four lanes during construction of the <br /> proposed project would not impact operations of Santa Ana Boulevard based on ADT. <br /> 10.2 Alternative Route Capacity Analysis <br /> Since the analysis indicates that the detour route would have adequate capacity to <br /> accommodate the demand, it is not anticipated that a substantial number of vehicles <br /> would shift to alternative routes. However, some vehicles may shift to upstream and <br /> downstream ramps along 1-5 to avoid the construction area, and it may be advantageous <br /> from a construction phasing perspective to encourage the use of alternative routes. As <br /> such, an additional roadway segment analysis along the potential alternative routes (17th <br /> Street, Fourth Street, Grand Avenue, Penn Way) was conducted to confirm that these <br /> alternative facilities have adequate capacity to accommodate any overflow from Santa <br /> Ana Boulevard. Fourth Street and 17th Street represent parallel facilities in which <br /> eastbound and westbound traffic could utilize instead of Santa Ana Boulevard. Grand <br /> Avenue and Penn Way have ramp locations north and south of Santa Ana Boulevard in <br /> which traffic could utilize during construction. The alternative route roadway segment <br /> analysis is summarized in the Table 12-1 below. <br /> Traffic/Circulation Study—Final May 18,2012 <br />
