The Recommended Choice: Segmented Hybrid Strategy
An evidence-based, equitable multimodal design combining the safety of Concept 3 with the community feasibility and parking protections of Concept 2.
When completing the City of Mountain View's online survey, we strongly recommend selecting Alternative B (Class IV Protected Bikeways & 4-to-3 Road Diet). Alternative B provides the ideal balance between Vision Zero safety, transit reliability, and housing equity.
Paint-only buffers fail Vision Zero goals; leaves cyclists exposed to door-zone collisions and high-speed traffic stress (LTS 3–4).
Delivers 35–47% crash cuts, physical Class IV protection, floating bus islands, and preserves vital multifamily parking on one side.
Removes 75–95% of on-street parking, creating severe equity burdens for apartment renters in Segment 1 lacking private garages.

Geometric Cross-Section
- Vehicular Lanes: 1 travel lane in each direction (10.5 ft) + continuous center Two-Way Left-Turn Lane (TWLTL, 10 ft) and dedicated left-turn bays.
- Bicycle Facilities: Directional Class IV protected bike lanes (6.5 ft) separated by concrete curb buffers and parked vehicles.
- Curbside Parking: Preserved on one side of the street (8 ft) in high-demand residential blocks, maintaining ~55–65% of stalls.
- Transit: Concrete floating bus boarding islands (8 ft wide) for VTA Route 40 stops at California, Stanford, and Latham.
Key Safety & Equity Interventions
- AB 413 Daylighting: 20 ft red curb zones upstream of all crosswalks with painted/bioswale curb extensions.
- Latham St Intersection: Seamless integration with the newly completed AI-detected protected left-turn signal.
- Parking Mitigation: Establish Residential Permit Parking (RPP) on adjacent side streets and negotiate nighttime shared-parking agreements with commercial lots.
Geometric Cross-Section ("Park-Side Promenade")
- Active Transportation: Widened 10–12 ft two-way separated sidepath/cycle track along the west (park/school) frontage.
- Vehicular Lanes: 2 travel lanes (11 ft each) + landscaped medians and dedicated turn pockets into Rengstorff Park access gates and Montecito Way.
- Green Infrastructure: Continuous 6–8 ft bioretention swales filtering runoff before entering Permanente Creek.
- Urban Canopy: 60+ new shade trees planted along the park buffer, mitigating urban heat island effect.
Park & School Safety Features
- School Routes (8-to-80 Standard): Direct, traffic-separated connection for Mariano Castro Elementary and Graham Middle School students.
- Mid-Block Crossings: Raised crosswalks with Rectangular Rapid-Flashing Beacons (RRFB) and pedestrian refuge islands connecting Monta Loma residents to the Community Center & Pool.
- Park Parking: Preserves 100% of dedicated off-street parking in Rengstorff Park lots.
Geometric Cross-Section
- Vehicular Configuration: 4-to-3 road diet (1 lane each direction + continuous center turn lane / landscaped median).
- Bikeway Class: Raised curb-protected Class IV bike lanes (7 ft) with concrete separation buffers (3 ft).
- Speed Calming: Road diet calms 85th percentile operating speeds from current >38 mph down to 25–28 mph.
- Freeway Gateway: Full alignment with VTA/Caltrans US 101 Charleston/Rengstorff interchange improvements.
Operational & Commercial Enhancements
- Middlefield Rd Intersection: Dutch protected intersection geometry with protected signal phases.
- Commercial Driveways: Center turn lane provides safe deceleration and queue storage for commercial vehicles without blocking through-traffic.
- Freight & Delivery: Accommodates industrial and commercial delivery access with dedicated curb loading bays.

Operational & Maintenance Commitments
Essential operational policies to ensure long-term durability and neighborhood harmony.
1. Dedicated Mini-Sweepers
City Public Works must procure compact 4–6 ft sweepers to ensure Class IV protected bike lanes remain clear of glass, leaves, and debris on weekly schedules.
2. Neighborhood Traffic Monitoring
Install pre- and post-construction automated speed/volume counters on Monta Loma side streets (Thompson, Laura, Mayfield) with rapid-response traffic calming if diversion occurs.
3. Caltrain Grade Separation Sync
Ensure interim Complete Streets infrastructure around Central Expressway utilizes modular components that directly tie into the long-term $395M rail underpass engineering envelope.
