0 AECOM growth rates calculated from the RTP model SED, as described above. 3. Future yeartraffic 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. 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. Deliverables: • Traffic Analysis • Traffic Management Plan Task 1.5 Prepare Alternatives Concepts/Geometric Preferred Alternative Development Roadway 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 and Typical Sections Railroad Track Design Provide track design plans, draft shoofly layout plans, to include shoofly track geometry plans, mainline track geometry plans, shoofly typical sections, mainline typical sections, track grading plans, and special trackwork plans. Railroad Coordination We will coordinate with the SCRRA/OCTA regarding alternative grade separation study alternatives, including additional trackage, construction activity constraints due to train operations, both freight and passenger trains, clearances, modifications to and reconstruction of a temporary at -grade crossing to facilitate construction of the grade separation. Railroad Permitting We will be responsible for assisting the SCRRA/OCTA in obtaining the Agreement with the SCRRA/OCTA. This will be done by: • Coordinate with the SCRRA/OCTA during the development of the preliminary plan for the grade separation and solicit their input and separation requirements. • Request the SCRRA/OCTA to prepare the Construction and Maintenance Agreement. • Meet and confer with the SCRRA/OCTA regarding the terms and conditions of the Agreement. • Furnish plans and cost estimates to the SCRRA/OCTA for said agreement. • Coordinate with the Project Surveyorfor the legal descriptions for the permanent bridge crossing of the SCRRA/OCTA right of way and the temporary construction easement. • Monitor and coordinate the development of the Agreement with the SCRRA/OCTA and the City. • Keep City updated with regards to the progress of the Agreement development. • Make recommendations to the City regarding the terms of project specific conditions addressed in the Agreement. • With City concurrence, negotiate with the SCRRA/OCTA the terms of project specific conditions. • Coordinate with and provide assistance to the City staff and City attorney regarding the terms of the agreement. • Coordinate the development and approval by the SCRRA/OCTA of shoofly plans. Shoofly plans prepared by AECOM. • Coordinate the development and approval by the SCRRA/OCTA of temporary at grade crossing for the shoofly.
