HARRISON STREET/OAKLAND AVENUE COMMUNITY TRANSPORTATION PLAN
INTRODUCTIONS
PROJECT OVERVIEW
Caltrans Funded (about 80%) /Oakland (about 20%)
A community-based decision making and problem solving process
Goal is to improve neighborhood livability along the streets
Built upon previous planning efforts on portions of the project area such as the TETAP Study and a previous study by Dowling Associates.
Project study area ties into several other planning efforts already underway such as the Broadway Specific Plan & Kaiser Center Expansion. BACKGROUND
PROJECT OVERVIEW
The Harrison/Oakland Community-Based Transportation Plan:
Review the entire project area as a whole
Look at workable and effective traffic calming measures
Balance transit, automobile, bicycle and pedestrian interests for a Multi-Modal transportation neighborhood
Set priorities, create cost estimates and identify funding sources

MULTI-MODAL TRANSPORTATION DESIGN
Harrison Street & Oakland Avenueprimarily residential uses with a mix of
institutional and commercial usesAll modes of travel must be considered- Pedestrians (ADA Issues)- Bicyclists- Buses- Vehicles
Maintain Connectivity throughout CityImpact to Economic Vitality of the Downtown CoreOakland Designated as a Transit-first City

ALTERNATIVES IN-BRIEF
Alternative 1: Pedestrian Improvements- Adds Bulbouts at side streets and crosswalks- Two-way conversion of couplet north of I-580
Alternative 2: Sidewalk Widening- Narrows travel lanes by restriping, two lane streets- Dedicated Bike Lanes- Widens Sidewalks where feasible
Alternative 3: Two-Way Conversion- Converts couplet to two way streets- Re-designs with signalization 29th St./Fairmount

ALTERNATIVES REVIEW
ALTERNATIVES IN-BRIEF
All Alternatives will:- Improve Quality of Sidewalks- Increase Street Trees Locations & Opportunities- Improve Pedestrian Pathways- Improve Bicycle Facilities - Improve or incorporate accessibility in design
Purpose of Review- Community input for major traffic pattern concept
changes, pedestrian improvements and transit proposals.
ALTERNATIVES REVIEW
URBAN DESIGN CONDITIONS
Re-configure Harrison & Oakland Two Way vs. One Way Major Impact to Neighborhood & Design Project
Option 1: Abandon and Close On-Off Ramps-regional transportation impacts-long time frame-environmental review required
Option 2: Reconfiguration of On-Off Ramps:-extremely long time frame, -environmental review -costly structural changes

Vehicle Intersection Levels of Service (LOS)
ALTERNATIVES ANALYSIS
Methodologies from the 2000 Highway Capacity Manual
- Scale is from A (best) to F (worst)
- Signalized intersection and all-way stop-controlled LOS calculated using the weighted average delay
- Side-street stop-controlled intersection LOS calculated using the weighted average delay of the intersection approach with the worst LOS
Oakland threshold is LOS “D”

MOTORIST LEVEL OF SERVICE
ALTERNATIVES ANALYSIS
Motorist LOS will be improved at the Harrison St/ 27th St-24th St-Bay Pl with all Alts
Alt 1 (2-way conversion)
Creates LOS problems north of I-580
Improves LOS at Fairmount-Orange at expense of access
Alt 2 (lane reduction)
Creates LOS problems at I-580 ramps
U-turns at Fairmount-Orange
Improves LOS at 29th at expense of access
PROJECT ALTERNATIVE 3
ALTERNATIVES ANALYSIS
Qualitatively assessed roadways near I-580
It would result in lower traffic capacity on city streets
Freeway operation not expected to be significantly affected
Freeway access modifications would require Caltrans’ approval
Further study needed for traffic operation’s feasibility
Harrison congestion reduced if freeway access from Santa Clara
ON-STREET PARKING INVENTORY
ALTERNATIVES ANALYSIS
Parking stall is considered 22 feet long
325 unmetered stalls counted along Harrison Street and Oakland Avenue
Project Alternatives will slightly reduce inventory, mostly at intersections
- Alternative 1 will result in 18 less stalls (6% reduction)
- Alternative 2 will result in 12 less stalls (4% reduction)
TRANSIT
ALTERNATIVES ANALYSIS
Alternatives propose 12-feet wide outer lanes wherever possible
Relocation of northbound Hamilton Pl bus stop to Westlake School crosswalk with bus bulb-out
Relocation of bus stops to the farside of most intersections with bus bulb-outs
Bus stops moved from Harrison St to Oakland Ave north of I-580 in Alternative 1 (2-way conversion)
Bus stops moved from Oakland Ave to Harrison St in Alternative 3 (full 2-way conversion)
ALTERNATIVES SUMMARY: QUALITATIVE ASSESSMENT
ALTERNATIVES ANALYSIS
Pedestrian experience improved with bulb-outs, plazas, and new path near I-580 for all Alts
Widened sidewalks on Harrison in Alt 2
Bicyclist experience improved with either Sharrows or bike lanes
Bike lanes in Alt 2 where possible
Sharrows in both directions on Harrison St and Oakland Ave in Alt 3
Bus operations improved for all alts with stop relocations
ALTERNATIVES SUMMARY: QUANTATIVE ASSESSMENT
ALTERNATIVES ANALYSIS
Motorist LOS will be improved at the Harrison St/ 27th St-24th St-Bay Pl with all Alts
Motorist access curtailed or eliminated at some side streets
24th St – eliminated for Alt 1, curtailed in Alt 2, altered for Alt 3
Fairmount-Oakland – curtailed for Alt 1
Stanley Pl - eliminated for all Alts
Santa Clara – EB access eliminated for Alt 2
ALTERNATIVES SUMMARY
ALTERNATIVES ANALYSIS
Alternatives will generally improve the pedestrian, bicycling, and transit experience
Preferred alternative will most likely require some mitigations to improve motorist LOS

Future Analysis Needed
Minimal for overall changes. Additional study for any intersections identified to produce LOS impacts
EIR for reduction of lanes overall. Additional study for any intersections identified to produce LOS impacts
Significant additional study/ Potential EIR trigger. Initial Study/Neg Declaration Analysis for closure of 24th Street, Stanley Place, and Two Way Conversion north of I-580
Initial Study/Neg Declaration Analysis for closure of 24th Street, Stanley Place, and Two Way Conversion north of I-580
Initial Study/Neg Declaration Analysis for closure of Stanley Place
Major level of ramp re- configuration must be justified by operational and/or safety requirements of the interchange which in turn must be supported by detailed traffic study

IMPLEMENTATION POTENTIAL
Key Design Aspects
Alternative 1: Pedestrian
Improvements
Alternative 2: Sidewalk
Improvements
Alternative 3: Two-Way
Conversion
Financial Considerations
Standard costs for implementation of bulbouts and pedestrian amenities. Minimal costs for re-striping required for lanes south of highway.
High Costs associated with widening of sidewalks and reducing curb-to-curb distances. Low-costs associated with re-striping to two lanes in the interim
High costs associated with additional studies and planning efforts.
Implementation Potential
Localized implementation per block. Feasible with City funding and implemented piece by piece.
Feasible with City funding. More difficult to implement piecemeal due to reduction in travel lanes. Striping for lane reduction possible in the short term.
Caltrans to initiate a Project Study Report, Project then to be included in State Transportation Improvement Program (STIP). Potential to not happen.
