Commissioners give early feedback on South Palo Alto bike–ped connectivity plan; priorities, crossing sites debated

The Planning and Transportation Commission spent the bulk of its May 14 meeting on an extended study session for the South Palo Alto bike and pedestrian connectivity project, reviewing an existing‑conditions report and draft design and evaluation criteria as staff begins a multi‑phase process to identify two locally preferred grade‑separated crossings of the Caltrain corridor.

Charlie Cole, senior transportation planner with the Office of Transportation, said the project’s purpose is to improve east–west bicycle and pedestrian accessibility across the rail corridor in southern Palo Alto and to identify two preferred crossing locations and concept designs taken to roughly 15% engineering for future funding, environmental review and construction.

What staff presented

Staff summarized the technical inputs used in the existing conditions report: a network accessibility analysis that maps walk and bike travel times using the street network (walk speed set at 3 mph, bike speed 10 mph), a bicycle “level of traffic stress” (LTS) analysis to identify high‑stress segments, and a big‑data origins‑and‑destinations analysis using a third‑party provider (Replika) filtered to one‑way trips under five miles that cross the Caltrain corridor. Staff noted the big‑data results are shown in transportation analysis zones (TAZs) consistent with Valley Transportation Authority modeling.

Staff asked for commissioner feedback on draft priorities and the initial list of candidate crossing locations (labeled a–f) shown in the packet. The project timeline calls for two phases of public engagement and development of conceptual crossing alternatives, followed by a final plan and an implementation and funding strategy; the team expects to produce 15% design concepts and aim for council adoption of a final plan in 2026.

Key concerns raised by commissioners and the public

- Study area boundaries and data presentation: several commissioners urged staff to broaden or better justify the geographic extent used for detailed analysis. Commissioners said neighborhood connections — especially to Barron Park, Gunn High School and other neighborhood destinations — felt underrepresented in some figures and asked for clearer maps showing specific destinations and time‑of‑day patterns (for example school peaks). Commissioner Gee recommended showing “hot spot” destinations overlayed on origins/destinations maps to clarify where trips concentrate.

- Methodology and inputs: Commissioners asked staff to confirm the assumptions in the accessibility maps (3 mph walk speed, 10 mph bike speed, and exclusion of high‑stress streets for bike travel) and to explain why some short walking shortcuts or informal paths (for example, an underused bridge near Cal Ave shown in field visits) may not appear in network calculations.

- Safety, personal security and flooding: multiple commissioners urged that evaluation criteria explicitly address personal security (crime prevention through environmental design), suicide prevention/response and flood risk in underpasses. Commissioner Templeton asked that “mental illness” and self‑harm risk be considered under design priorities; others urged attention to lighting, sight lines and pump/mitigation needs where underpasses are in low‑lying areas.

- Network connectivity and future demand: commissioners emphasized that demand projections should account for planned housing growth and likely trip patterns to and from the San Antonio/101 growth area; several commissioners noted the importance of modeling how adding one crossing changes flows and interacts with other crossings (serial dependence). Staff said the evaluation will include projected weekday peak usage and account for future land‑use scenarios.

Candidate locations and commissioner preferences

Staff presented six candidate crossing opportunity locations (a–f) developed from existing data and feasibility considerations. Commissioners discussed pros and cons at length. Preferences voiced during the session clustered around the following:

- Several commissioners and commenters supported a site in the Loma Verde/Matadero corridor area (candidate area generally referred to as “b” in staff materials) as a high priority because it lies in the center of a long stretch without crossings and could serve existing neighborhoods.

- Commissioners also debated southern options near San Antonio (c/e/f on staff maps). Some favored an option that better serves anticipated growth near San Antonio/101 and connects to Mountain View’s existing facilities; others urged caution because San Antonio Road is a high‑traffic corridor and calmer neighborhood‑street connections might be preferred.

- Commissioners noted that the city is concurrently advancing rail grade‑separation projects at Meadow and Charleston; staff said those vehicle grade separation efforts are separate but that this bike/ped project should be coordinated with related work and planned construction schedules.

Next steps and timeline

Staff said phase 1 community engagement is ongoing and will inform the development of alternative crossing concepts in phase 2. The project team expects to complete 15% conceptual designs for two preferred crossings and produce a final plan that would include an implementation and funding strategy; the schedule anticipates community and council steps through 2026. Staff emphasized the role of competitive grant funding for later design and construction phases.

Why it matters: the project could alter east–west connectivity citywide for pedestrians and bicyclists, affect school commute routes, and change how new housing growth interfaces with active‑transportation networks. Commissioners asked staff to explicitly factor future housing growth, school peak travel, personal security/CPTED, and flood resilience into the final evaluation framework.
