VTA Light Rail in Median Landscaping and Sound Walls on Both Sides Example Cross-section Between Fair Oaks Ave. and Vienna Dr. 5City of Sunnyvale – Tasman Drive Pedestrian-Bicycle Improvements Study – July 2025 Tasman Dr. west of Vienna Dr.
Since 2020 (during the COVID-19 Pandemic)
Existing Temporary Condition
• Temporary lane closure on
Tasman Dr. (between Tasman Ct.
and Vienna Dr.)
• Creates a temporary two-way
bicycle and pedestrian pathway
• Includes temporary barriers
separating the path from
vehicular traffic
• Not designed to ADA or for
emergency access

Multi-Use Path
Design Alternative 2:
Sidewalk and Buffered Bike Lane
Design Alternatives – Not to scale
Example Cross-section Between Fair Oaks Ave. and Vienna Dr. 7City of Sunnyvale – Tasman Drive Pedestrian-Bicycle Improvements Study – July 2025 Design Alternative 1: Multi-Use Path
W Frontage Rd,
Berkeley, CA
Typical midblock cross-section
• Wide surface (12’ min) that pedestrians and bicycles share • Path at sidewalk level, separated from autos by curb and in limited locations by landscaping • Two-way walking and biking travel on both sides of the street • Tree impacts: 12 likely, 66 potential
Multi-Use Path
with raised
curb
Moffett Park Drive,
Sunnyvale, CA
8City of Sunnyvale – Tasman Drive Pedestrian-Bicycle Improvements Study – July 2025 • Separates bicycles and autos
• Average 6’ wide bike lane
• 4.5’ painted buffer between bikes and autos
• No vertical separation
• Pedestrians are separated from both auto traffic and bike lane by raised curb and in limited locations by landscaping
• Tree impacts: 1 likely, 6 potential
Design Alternative 2: Sidewalk and Buffered Bike Lane

Traffic Analysis and Counts
• Count data:
Temporary lane closure
Recent counts between Vienna Dr. and
Lawrence Expwy.
• Existing conditions and concerns:
AM peak eastbound queue at Lawrence Expwy.
Congestion during Levi’s Stadium events
• Analysis results of lane removal:
No notable effect to travel time and delay
Some additional traffic queues eastbound at
Lawrence Expwy.
No notable effect to queueing west of Vienna Dr.

NextDoor and Facebook)
➢ Engaged with over 400 peopleSticky notes on presentation boards left by meeting attendees
11City of Sunnyvale – Tasman Drive Pedestrian-Bicycle Improvements Study – July 2025 • DPS has concerns with both design alternatives
Reduced travel lanes = narrower roadway clear width
Difficulty accessing mobile homes from Tasman Drive
Potential need to direct drivers to move over
Increased response times
• Design Alternative 1 has detrimental impact to public safety
Drivers cannot pull to right onto raised path
Emergency vehicles have no room to pass on left
California Vehicle Code passing laws
• Design Alternative 2 – slightly less concern
No vertical elements
Drivers would pull into bike lane
Emergency vehicles would pass on the left
Public Safety and Emergency Access Impacts
Design Alternative 1
Design Alternative 2
12City of Sunnyvale – Tasman Drive Pedestrian-Bicycle Improvements Study – July 2025 • Mobile Home Deliveries
Final design would account for space
Buffered bike lanes roadway width is
similar to existing
• More Midblock Crossings
Safety concerns of adding rail crossings
Grade separated crossings are expensive

14City of Sunnyvale – Tasman Drive Pedestrian-Bicycle Improvements Study – July 2025 Temporary Lane Closure
Temporary
Lane Closure
• Intended to be temporary during shelter in place order • Temporary construction devices
• Not designed to meet ADA requirements
• Not designed for emergency access
15City of Sunnyvale – Tasman Drive Pedestrian-Bicycle Improvements Study – May 2025 BPAC Recommendation
16City of Sunnyvale – Tasman Drive Pedestrian-Bicycle Improvements Study – July 2025 Motion Approved 6-0, 1 abstention
BPAC Recommendation to City Council
• Implement the project (Design Alternative 1) in phases:
Phase 1 – Remove one travel lane on each direction on Tasman Dr. between Fair Oaks Ave. and Vienna Dr. to install a Class I Multi-use path on both the north and south side of Tasman Dr. Phase 2 – Remove one travel lane on each direction on Tasman Dr. between Vienna Dr. and Lawrence Expwy. to install either a Class I Multi-Use path or sidewalk and Class IIB buffered bicycle lane on both north and south sides along Tasman Dr. between Vienna Dr. and Lawrence Expwy.
Continue and expand temporary closure until Phase 1 is completed – continue existing closure and temporary bike lane on eastbound Tasman Dr. Provide a new lane closure and
temporary bike lane on westbound Tasman Dr. between Vienna Dr. and Fair Oaks Ave.

19City of Sunnyvale – Tasman Drive Pedestrian-Bicycle Improvements Study – July 2025 Staff Recommendation
• Alternative 3: Sidewalk and Buffered Bicycle Lane: Fair Oaks to Vienna. Approve Design Alternative 2 to remove one travel lane in each direction on Tasman Drive between Fair Oaks Avenue and Vienna Drive (Phase 1 segment) to install sidewalk and a Class IIB buffered bicycle lane on both north and south sides along this segment, find that the action is exempt from CEQA pursuant to CEQA Guidelines Section 15301(c) and Public Resources Code Section 21080.25(b)(1), and recommend that the City Council direct staff to include the concept plan as an unfunded project in the FY 2025/26 Budget pending future identification of funding. • Alternative 6: Pre-Pandemic Configuration: Vienna to Lawrence. Maintain the existing (pre-COVID- 19 pandemic) Tasman Drive configuration between Vienna Drive and Lawrence Expressway (Phase 2 segment) pursuant to the Active Transportation Plan (no change to pre-pandemic conditions).
