Transportation Commission Study Session
Public Comments
August 26, 2009
Significant increase in delays and queues along Park Street during the peak times will
adversely impact businesses and commute traffic
Access to Miller- Sweeney Bridge from 9th Street in Oakland will be eliminated
increasing congestion along Park Street
County's bridge operations (raising and lowering) for maritime traffic will be affected
because queues are projected to extend well beyond the bridge
Elimination of access to Miller Sweeney Bridge via 9th Street in Oakland will impact
truck deliveries to businesses
Since the project impact analysis is for the future year 2035, an additional analysis
should be conducted for an interim year like 2020 to fully understand the impacts
immediately after the completion of the project
Bicycle access to Embarcadero via 29th Avenue should be maintained during
construction and after the completion of the project
The various phases of the project should be coordinated
Staff Comments
Project provides several benefits to the freeway and regional traffic but
increases congestion, delays, and queues in Alameda
The project will increase traffic volumes and delays and change traffic
circulation in the Park Street Triangle area, north of the Park Street Bridge
No mitigation is provided to address queues and delays along Park Street.
The queue at the northbound Park Street increases by 1000 feet during the
morning peak hour and could extend beyond Buena Vista Avenue
The project has reduced capacity at the 23rd Avenue on ramp to northbound
I -880 by consolidating the ramps causing significant increase in delays
The project will also add a new signal at the new consolidated on ramp
creating additional delays for motorists attempting to take northbound I -880
from the cities of Alameda and Oakland
Staff Comments Continued...
The signalized intersections of Blanding Avenue and Clement Avenue along
Park Street will have significant impacts (increase in delays and queues) due
to the project
Increase in queues and delays will impact emergency access along Park
Street
Future development along Ford Street area will adversely impact traffic
access by increasing delays and queues at Ford Street and 29th Avenue
intersection
Traffic that currently uses 9th Street to access Miller Sweeney Bridge will be
diverted to Park Street
Due to a shared left turn and through lane at 23rd Ave. and 7th Street in
Oakland, traffic will suffer additional increase in delays and queues for traffic
from Alameda accessing 23rd Ave. on ramp to I 880
Staff Recommendations
Include the following 1 to 6 mitigations in the environmental document as project mitigations
1. Provide Transit Queue Jump lanes during peak times by limiting parking from Buena Vista to the
Bridge. These lanes could become exclusive transit lanes. The parking limitations will coincide with the
peak direction of travel.
2. Provide full traffic signal detection at three signals (Buena Vista Avenue, Clement Avenue, and
Blanding Ave.) using most up -to -date technology.
3. Modify signals and cabinets to accommodate transit queue jumps.
4. Provide appropriate signage and striping changes to implement the peak time queue jumpers /exclusive
transit lanes.
5. Provide Opticom at upgraded signals (Buena Vista Ave., Clement Avenue, and Blanding Avenue) to
allow transit buses to have signal priority.
6. Include transit improvements along 23rd and 29th Avenues in Oakland to improve transit access to the
freeway.
7. Caltrans accident data show that southbound I -880 segment at Fruitvale Ave. off-ramp is worse than
the northbound I -880 at 29th Avenue and 23rd Avenue off-ramps (current project). Southbound I 880
freeway improvements, including improved access to Fruitvale Avenue, at Fruitvale Ave. off-ramp
should be pursued as a priority.
