6 Meadow + Charleston Trench TEMPORARY Permanent Fence (Typical) Temporary Fence (Typical) EXAMPLE SECTION - TRENCH

7 PLACEHOLDER FOR 3D ANIMATION

8 Meadow + Charleston Trench Pros Less visually impact with trains are below existing grade between Charleston and Meadow Cons Blocks creeks at Adobe and Barron potential flooding issues Requires subsurface right-of-way ROW acquisition for deep walls o Limits types of planting allowed along Alma Street and private properties backing up to Caltrain ROW Requires high fence along trench walls for safety to protect high-voltage lines High long-term maintenance cost o Trench is below ground water requires pumping ground water and runoff to sewer system o Right-of-Way required for pumping station Requires design exception from Caltrain for 2% grade Closes Meadow and Charleston for construction of roadway bridges o Major utilities relocations along Meadow and Charleston Relocate railroad cross-over just north of San Antonio Station

9 Meadow + Charleston Hybrid TEMPORARY Sound Wall Barrier (Typical) Temporary Fence (Typical) EXAMPLE SECTION - HYBRID

10 PLACEHOLDER FOR 3D ANIMATION

11 Meadow + Charleston Hybrid Pros Does not block creeks Minor right-of-way impacts at driveways Restore landscaping with trees at completion of construction Shorter shoofly than trench Lower long-term maintenance costs No Caltrain railroad design exceptions required Cons Stage construction severely impacts traffic o Closes portions of Alma, Meadow and Charleston for lowered roadways to maintain 2 lanes of traffic Alma Street reduced to 2 lanes (one in each direction) during construction (there are 4 lanes existing) Meadow and Charleston reduced to 2 lanes Relocate railroad cross-over just north of San Antonio Station

12 Meadow + Charleston Viaduct Sound Wall Barrier (Typical) TEMPORARY Temporary Fence (Typical) EXAMPLE SECTION - VIADUCT

13 PLACEHOLDER FOR 3D ANIMATION

14 Meadow + Charleston Viaduct Pros Minimal impact to roadways during construction Option to build without shoofly Landscaping can be fully restored on both sides of track Opportunity for linear park Does not block creeks Low long-term maintenance cost Minor utility impacts Cons Requires design exception from Caltrain for 1.4% grade Visual impact with raised railroad Relocate railroad cross-over just north of San Antonio Station

15 Pedestrian / Bicycle Discussion Pedestrian / Bicycle considerartions are being added to alternative evaluations.

16 Adopted City Council Criteria

17 Meadow + Charleston Evaluation Matrix Adopted Criteria by City Council Hybrid (MCL) Trench (MCT) Viaduct (MCV) Comments Improve East-West Connectivity Same connectivity for all three in the final configuration Reduce traffic congestion and delays Provide clear, safe routes for pedestrians and bikes Support continued rail operations Finance with feasible funding sources Same traffic improvements for all three in final configuration Safe routes for all three in final configuration Temporary railroad (shoofly) constructed for continuous rail operations for two checking on viaduct solution Improvement Minimize right-of-way acquisition Reduce rail noise and vibration Noise and vibration designs can be incorporated into all three. Impact Maintain or improve local access Same improvement for all three in final configuration Minimize visual changes along the corridor Minimize disruption and duration of construction Slight improvement for the trench, greatest impact for the viaduct. Order of Magnitude Cost $ M* 3x to 4x Hybrid ** 2x to 3x Hybrid** **Construction cost still being evaluated * Preliminary (Subject to Change)

18 Meadow + Charleston Evaluation Matrix Technical Criteria Other Considerations Hybrid (MCL) Trench (MCT) Viaduct (MCV) Comments Traffic Impacts During Construction Bike/Ped Impacts during construction Construction Duration Improvement Impacted Creek Groundwater Impacts Impact

19 Financing Update Once the construction costs are completed then we will be able to match up where there are opportunities for funding and financing sources and where there are gaps and how/if these gaps can be closed. 19
