1 Ravenswood Avenue Railroad Crossing Project City Council Meeting Study Session April 4,

2 Presentation Outline Project Background Review Current Alternatives City Council Requests Council Direction Requested Next Steps 2

3 Council Feedback Requested Third track location Station configuration Hybrid alternative to move forward 3

4 Station Configuration Existing station platform Proposed platform additional width OCS Pole Height ~ 30 ft Caltrain Station Looking North North of Ravenswood 4

5 Project Background Previous Studies Feasibility Study, 2003 and 2004 Basic assumptions Expand 2 to 4 tracks Study 4 alternative methods At-grade at Atherton & Palo Alto boundaries Evaluate all 4 Menlo Park crossings Options considered Trench alternative elevate roads, lower tracks Overpass alternative elevate roads, tracks remain Underpass alternative lower roads, tracks remain Split alternative lower roads, elevate tracks 5

6 Trench Alternative Issues Requires roadway raising Deep trench, high fences Depressed station platforms High cost Utility relocations High construction impacts 6

8 Overpass Alternative San Antonio Road, Mountain View Issues Requires 30 ft bridge Overpass length: 1,100 ft Requires raising El Camino Real Major visual impacts Largest footprint 8

9 9

10 Underpass Alternative Jefferson Avenue, Redwood City Issues Retaining walls Limits access to adjacent properties Side street connectivity 10

11 11

12 Split (Hybrid) Alternative Holly Street, San Carlos Issues Long embankments Raised tracks Improved connectivity Reduced impact to adjacent properties 12

14 Feasibility Study General Findings Trench Alternative Partial trench due to City limits requires difficult road connections Construction required along entire length of tracks Overpass Alternative Largest footprint, major visual impacts Least desirable of all alternatives studied Underpass Alternative Road connection changes Long approaches required to meet elevations Split (Hybrid) Alternative Maintains road connections Requires raised track embankment 14

15 Viaduct Option 2003 study found viaduct option infeasible Constraints - City limits - Crossover tracks - Station area - Caltrain design criteria Hybrid grade separations needed Undesirable by community 15

16 Viaduct Option Atherton Caltrain Station Platform Atherton Channel Viaduct Encinal Ave Glenwood Ave Alternative A Existing Elevation Oak Grove Ave Menlo Park Caltrain Station Platform Ravenswood Ave Alternative B Alternative C Crossover Tracks San Francisquito Creek 16

17 Following Studies Coordination with adjacent cities Caltrain Modernization Updated HSR/Blended System Rail Subcommittee and City Council meetings, Spring 2015 Rail Policy & Position Statement Direction for current study 17

18 Scoping Current Study Project Study Report (PSR) Measure A grant funding Alternatives evaluation Basic assumptions Maintain 2 tracks and allow for possible 3 rd track in future Study 2 alternative types: Underpass and Hybrid At-grade at Atherton & Palo Alto boundaries Prioritize Ravenswood Avenue crossing 18

29 City Council Requests Legal counsel regarding passing track requirement Assess impacts of third track location Perform direct outreach to Felton Gables and Linfield Oaks residents Construction cost estimates 29

30 City Council Requests Legal counsel regarding passing track requirement Assess impacts of third track location Perform direct outreach to Felton Gables and Linfield Oaks residents Construction cost estimates 30

31 Passing Track Grant requirement Consistent with the Measure A funding requirements, at least one alternative would be developed to allow for the addition of a third passing track through Menlo Park, which is currently an alternative for the Caltrain/HSR blended system. Legal counsel - At least through project study area Caltrain s interpretation - Currently proposed Caltrain/HSR blended system Middle 3 Track option, continuous from San Mateo to south Palo Alto 31

32 Passing Track 32

33 City Council Requests Legal counsel regarding passing track requirement Assess impacts of third track location Perform direct outreach to Felton Gables and Linfield Oaks residents Construction cost estimates 33

34 Third Track Two Potential Locations for a Third Track: - Option 1: In the center of the two main tracks (Outboard platforms at the station) - Option 2: On the outside of the main tracks (Center platform at the station) Opportunities and constraints for each option 34
