• Parking Data Collected in Oct.
2024
Location:
• On-street on Hollenbeck Ave. and
side streets
• Off-street on driveways
Date/Time:
• Midweek
2-6pm, 11pm-1am

13City of Sunnyvale – Hollenbeck Avenue Bike Lane Study – May 2025 Alternatives
14City of Sunnyvale – Hollenbeck Avenue Bike Lane Study – May 2025 • Right-of-Way Constraint
Only considering improvements that will fit within existing curb-to-curb Generally 40’ width curb-to-curb
• Lane Width Requirements
Vehicle Lane – 10’ minimum width
Vehicle Lane on Bus Route – 11’ minimum width
• Northbound Hollenbeck from Fremont to Remington
Bike Lane – 5’ minimum width
Parking Lane – 8’ minimum width
General Constraints in Developing the Alternatives
15City of Sunnyvale – Hollenbeck Avenue Bike Lane Study – May 2025 • Intersection of Hollenbeck Ave./Remington Dr.
Downtown Specific Plan Amendment
• Approved by Council in Aug. 2020
• Environmental Impact Report (EIR) identified impact
• Feasible mitigation measure
Restripe NB and SB approaches to add dedicated left-turn lanes • Current road width can't accommodate turn lanes and bicycle lane • Potential to change mitigation measure
Requires an amendment to the Downtown Specific Plan/Environmental Impact Report

Parking Implications
Danforth <-> Remington Remington <-> Fremont Fremont <-> Alberta Otherwise, walk time to available parking = 2-4
minutes
May include pedestrian crossing improvements
Assumptions:
• All parking demand shifts to side-
streets
• Demand not relocated to
driveways
• Utilized peak demand for each
block segment for analysis

22City of Sunnyvale – Hollenbeck Avenue Bike Lane Study – May 2025 • Special Design Considerations
Same as Alternative 1 for Remington Dr., Torrington Dr., Fremont Ave. • Design Tradeoffs
Maximize on-street parking spaces with the proposed bike lanes Minimize parking spillover to side streets
Incorporate alternating on-street parking could have an effect on vehicle speed
Alternative 2 – Bike Lanes with Parking on One-Side

= 1-5 maximum parking displaced
Assumptions:
• Displaced parking relocates
within the same side of the street
(on Hollenbeck or on side street)
• Demand not relocated to
driveways
• Utilized peak demand for each
block segment for analysis
= 5-7 maximum parking displaced
