HomeMy WebLinkAboutAgenda Report - February 20, 19854 -WAY SIOP SIGNS ESTABLISHED AT SlT)C= AND PINE SIP =1 Council was apprised that the intersection of Stockton and Pine Streets has warranted signals for several years. Because of the number and severity of accidents at that location, it appears that the installation of a 4 -way stop as an interim measure would be very beneficial. The accident record for the last several years was presented to Council for its perusal. A lengthy discussion followed with questions being directed to Staff. RES. NO. 85-34 On motion of Mayor Pro Tempore Hinchman, Snider second, Council adopted Resolution No. 85-34 establishing 4 -way stop signs at Stockton and Pine Streets. The motion carried by the following vote: Ayes: Council Members - Hinchman, Olson, Reid, and Snider (Nbyor) Noes: Council Members - Pinkerton Absent: Council biers - None Staff was requested to submit a report of the accidents that have occurred at the subject intersection to the Council six months from this date. FROM: City Manager DATE: SUBJECT: February 1, 1985 COUNCIL COMMUNICATION 4 -Way Stops - Beckman Road/Lodi Avenue Beckman Road/Pine Street Stockton Street/Pine Street RECOMMENDED ACTION: That the City Council adopta resolution establishing the intersections of Beckman Road and Lodi Avenue, Beckman Road and Pine Street, and Stockton Street and Pine Street as 4 -Way stops BACKGROUND INFORMATION: In April, 1.983, the Engineering Department conducted traffic studies with*re alts that showed 4-Waystops were not warranted at either of the Beckman Road locations. At that time, in an effort to reduce accidents, approach warning signs were installed, additional pavement markings were added, and measures were taken to improve intersection visibility. The Engineering Department has recently completed a follow-up study to determine whether the corrective measures have reduced. accidents, or if other traffic condi- tions now exist to warrant the installat.ion of 4 -Way stops as shown on Exhibits A C B. The study showed .that although traffic volumes on Beckman Road, Lodi Avenue and Pine Street have not increased, the number of accidents per year correctible by 4 -Way stop signs have increased from 4 accidents to 7 at Lodi Avenue, and, from 3 to 5 at Pine Street.`as shown on attached Exhibits C and D respectively. It does not appear that there are any changes at the intersection that would appre- ciably decrease -the number of accidents and that the best way to reduce the number and severity.of the accidents is with a 4 -Way stop. The intersection of Stockton and Pine has warranted signals for several years. Because of the number and severity of accidents at that location, it appears that the installation of a 4 -Way stop as an interim measure would be very beneficial. The accident record for the last several years is shown on Exhibit E. k L. Ronsko ublic Works Director Attachments JLR/cag APPROVED: FILE N0. HENRY, 'A.:_GLAVES, City Manager A$: EXHIBIT A .
