Resolution 2. Reconfiguration Plan 3. Intersection Plan 4. Cost Information Summary Statement: Petaluma Boulevard North from Washington Street to Lakeville Street currently has the following lane configuration: Two 9.5' wide lanes and one 6' wide parking lane in each direction except at the intersections where some parking is omitted. Due to the lack of adequate street width, and the reasons noted below, it is proposed that the lane configuration be changed to one 11' lane and one 8' parking lane in each direction with a 12' two way left-tuni lane in the center. Changing to this proposed configuration will result in the following: 1. The traffic signal at the intersection of Washington Street and Petaluma Boulevard North will facilitate synchronized left turn movements instead of inefficient split phase movements and will result in improved signal operation, efficiency, and through times at present and in the future. 2. Wider travel and parking lanes will provide more vehicle buffer space and should result in fewer collisions. 3. Crosswalks will become safer due to a decrease in the number of lanes necessary to cross. 4. Access to businesses will be dramatically improved because patrons and employees will no longer be forced to park with two wheels on the sidewalk in order to safely access their automobiles. 5. Bicycle safety will be improved due to the increased width of the travel way and adjacent parking area. 6. Access and egress from adjacent streets will be more efficient due to the presence of a two way left -turn lane. The end result of this lane reconfiguration change will be a roadway and an intersection that flows more smoothly and allows for more through volume now and in the future. Recommended Citv Council Action/Suggested Motion: Adopt the attached resolution, approving the lane and signal reconfiguration plan.

EXECUTIVE SUMMARY: Petaluma Boulevard North from Washington Street to Lakeville Street currently has the following lane configuration: Two 9.5' wide lanes and one 6' wide parking lane in each direction except at the intersections where some parking is omitted. Due to the lack of adequate street width, and the reasons noted below, it is proposed that the lane configuration be changed to one 11' lane and one 8' parking lane in each direction with a 12' double left -turn lane in the center. Changing to this proposed configuration will result in the following: 1. The traffic signal at the intersection of Washington Street and Petaluma Boulevard North will facilitate synchronized left turn movements instead of inefficient split phase movements and will result in improved signal operation, efficiency, and through times at present and in the future. The re -phasing of the signal at this intersection will allow for simultaneous protected left turns from Petaluma Boulevard North onto Washington Street. A full right turn lane on Southbound Petaluma Boulevard North at Washington Street will also be installed. Sufficient stacking room at the intersection will also be maintained in order to take full advantage of the more efficient signal phasing. 2. Wider travel and parking lanes will provide more vehicle buffer space and should result in fewer collisions. The majority of accidents reported on this stretch of roadway over the past five years have been "sideswipe" accidents. This lane configuration will help minimize these and other types of accidents. 3. Crosswalks will become safer due to a decrease in the number of lanes necessary to cross. Vehicle/pedestrian conflicts have been reported on this stretch of roadway. The elimination of one hazardous crosswalk at Kent Street and the presence of fewer through lanes will help minimize such conflicts. Additionally, pedestrian enhancements can be incorporated into the design to reduce pedestrian/vehicle conflicts. 4. Access to businesses will be dramatically improved because patrons and employees will no longer be forced to park with two wheels on the sidewalk in order to safely access their automobiles. This will allow for the placement of trees on this entire stretch which will, in turn, spur redevelopment. 5. Bicycle safety will be improved due to the increased width of the travel way and of adjacent parking. 6. Access and egress from adjacent streets will be more efficient due to the presence of a two way left - turn lane. Some of the accidents reported on this stretch of roadway were "broadside" accidents. This lane configuration will help minimize these and other types of accidents. The end result of this lane configuration change will be a safer more efficient stretch of roadway and an intersection that flows more smoothly and allows for more through volume now and in the future. 2 2. BACKGROUND: The "Road/Streetscape Improvements - Petaluma Boulevard" Capital Improvement Project, as approved in the FY 05/06 CIP, entails repaving Petaluma Boulevard North from Washington Street to Lakeville Street. It also entails streetlight beautification, signal replacement, tree planting, and concrete sidewalk upgrades over that same stretch. This plan adds signal modification and the lane configuration changes outlined above. ALTERNATIVES: A. Accept this proposed lane configuration change. B. Reject this plan and after paving, re -stripe with four I I' lanes and two 3' shoulders, and eliminate all parking between Lakeville Street and Washington Street. 4. FINANCIAL IMPACTS: The budget for the streetscape project has already been approved. All costs associated with the signal modification and the lane configuration changes will fall within that budget. Please see Attachment D for the incremental cost increases of these items. 5. CONCLUSION: The end result of this lane configuration change will be a safer more efficient stretch of roadway and an intersection that flows more smoothly and allows for more through volume now and in the future. 6. OUTCOMES OR PERFORMANCE MEASUREMENTS THAT WILL IDENTIFY SUCCESS OR COMPLETION: This project will be completed and accepted in FY 2005-06. RECOMMENDATION: Adopt the attached resolution, approving the lane and signal reconfiguration plan. Attachment 1 RESOLUTION # 2005 - DISCUSSION AND ACTION APPROVING THE PROPOSED LANE RECONFIGURATION PLAN FOR PETALUMA BOULEVARD NORTH FROM WASHINGTON STREET TO LAKEVILLE STREET C200304 WHEREAS, the existing lane configuration on Petaluma Boulevard North from Washington Street to Lakeville Street and the existing signal at Washington Street and Petaluma Boulevard North are inefficient; and WHEREAS, Winzler and Kelly, a reputable engineering firm, has performed an intersection study and traffic calculations finding that the circulation can be enhanced by implementing this lane reconfiguration plan; and WHEREAS, the City Engineer, City Planning Department, and City Consultant Traffic Engineer fully support the implementation of this proposed lane reconfiguration plan to improve intersection safety and through times. NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Petaluma hereby: 1. Approves the proposed lane reconfiguration plan. 2. Directs staff to complete the final design including the proposed lane reconfiguration plan.
