The analysis will include examination of the following intersections: • Santa Ana Bld./1-5 On and Off -ramp. • Santa Ana Bld./Fuller St.. • Santa Ana Bld./Lincoln Ave. • Santa Ana Bld./Santiago Street. We will coordinate with City staff and the PDT to develop an appropriate methodology for forecasting year 2035 volumes at the study locations, relying on the SCAG RTP (regional) traffic model (or as the City requires) data to forecast year 2035 volumes. Specific tasks to be performed for the traffic operations analysis include the following: 1. Peak period traffic counts will be collected at up to three study intersections, for two (a.m. and p.m.) three-hour peak periods. The peak periods to be evaluated will be determined in conjunction with the PDT. 2. Future year traffic volumes for the locations identified for examination will be developed using growth rates calculated from the RTP model SED, as described above. 3. Future year traffic volumes will be developed for the four build alternatives described above. 4. Opening year traffic volumes will be developed using growth rates calculated from the RTP model SED for an intermediate year, to be determined by the PDT. 5. The resulting intersection levels of service will be calculated using Highway Capacity Manual (HCM) 2000 analysis methodologies. 6. Based on the future levels of service, intersection lane geometrics will be identified to maintain minimum level of service standards. 7. Weaving operations will be analyzed for traffic movements on the westbound segment of Avenue P between the Avenue P Westbound Connector Road and Third Street for Alternatives 1 and 2 using Highway Capacity Manual (HCM) 2000 analysis methodologies 8. The results of the traffic operations analysis will be presented in a technical study. This study will document the level of service analysis methodologies employed, existing traffic conditions, forecast future (opening year and design year) traffic conditions for each alternative, and improvements needed to maintain satisfactory operations in each analysis year. 9. Our traffic subconsultant will attend up to eight meetings related to the proposed project. Engineering Studies of Various Feasible Plan Alternatives Roadway Task 1.5 Prepare Alternatives Concepts/Geometric Preferred Alternative Development Preliminary engineering will focus on the physical characteristics of the project area and the engineering features and standards required to develop the project. The alternatives we will develop will need to address cost effective ways to resolve access issues, for both vehicle traffic and rail traffic, to the local businesses. They will also address the potential expansion/changing needs of the SCRRA/OCTA. Deliverables: Preliminary Roadway Plans, Profile (1"=20' Scale), and Typical Sections City of Santa Ana
