CC - Item 3I - Lengthening Left Turn Lanes Walnut Grove Ave at Hellman• • ROSEMEAD CITY COUNCIL STAFF REPORT TO: THE HONORABLE MAYOR AND CITY COUNCIL FROM: ANDREW C. LAZZARETTO, CITY MANAG DATE: NOVEMBER 28, 2006 SUBJECT: LENGTHENING OF LEFT TURN LANES FOR NORTHBOUND AND SOUTHBOUND WALNUT GROVE AVENUE AT HELLMAN AVENUE SUMMARY The recent traffic signal modification at the intersection of Walnut Grove Avenue and Hellman Avenue has caused a need for additional storage length for left turn traffic. This need is in both the northbound and southbound directions. With the new traffic signal at Hellman Avenue and the 1-10 Freeway ramps and the associated signal operation, this left turn storage demand is not likely to diminish. Staff Recommendation Staff recommends that the City Council approve the Traffic Commission's recommendation to: • Lengthen the southbound left turn lane to 120 feet; • Lengthen the northbound left turn lane to 200 feet; • Install 85 feet of "No Parking Any Time" on the west side of Walnut Grove Avenue; and • Install 185 feet of "No Parking Any Time" on the east side of Walnut Grove Avenue. ANALYSIS Field observations during various times of the day revealed that the existing left turn lanes on Walnut Grove Avenue at Hellman Avenue were not long enough to store all left turning vehicles. This results in vehicles blocking the Number 1 lanes of through traffic in each direction. In addition, vehicles wanting to access the left turn lane in the northbound direction were unable to "sneak" around the vehicles in the Number 1 lane because of the double yellow centerline separating traffic. The traffic signal operation at this intersection has changed with the installation of the traffic signal at the 1-10 ramps. These two signals are connected and work together as one unit and the left turn storage demand is not likely to diminish. APPROVED FOR CITY COUNCIL AGENDA: ' 0 0 City Council Meeting November 28, 2006 Page 2 of 2 The extension of the northbound left turn lane will require the removal of parking on both sides of Walnut Grove Avenue from Hellman Avenue to approximately 380 feet to the south. On the west side of Walnut Grove Avenue, there will be a removal of approximately 6 parking spaces. On the east side of Walnut Grove Avenue, there will be a removal of approximately 7 parking spaces. The number of removed parking spaces is based on a parking length of approximately 20 feet and the number of driveways on either side of the street. Exhibit A depicts the proposed recommendations.
