HomeMy WebLinkAboutAgenda Report - February 6, 19854 -WAY STOP SIGNS Agenda item a -1-L - "Adopt Resolution establishing 4 -way
ESTABLISH® AT stops at Beckman and Lodi Avenue, Beckman and Pine and
BBCKWN;AND UDI Stockton and Pine: was introduced by Public Works Director
AVENUE AND BBCiiSMAN Ronsko who apprised the Council that in April, 1983, the
AND PINE SIRE IS Engineering Department conducted traffic studies with results
that showed 4 -way stops 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 coapleted a follow-up
study to determine whether the corrective measures have
reduced accidents, or if other traffic conditions now exist
to warrant the installation of 4 -way stops as shown on
Exhibits presented to Council for perusal. The study showed
that although traffic volumes on Beckman Road, Lodi Avenue
and Pine Street have not increased, the number of accidents
per year correctable by 4 -way stop signs have increased from
4 accidents to 7 at Lodi Avenue, and from 3 to 5 at Pine
Street.
It does not appear that there are any changes at the
intersection that would appreciably 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 nunber 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 for Council's information.
A lengthy discussion followed with questions regarding the
subject being directed to Staff.
'a M. NO. 85-21 Following discussion, on motion of Mayor Snider, Hinebman
second, Council adopted Resolution No. 85-21 establishing
4 -way stops at Beckman and Lodi Avenue and Beckman and Pine
Street. Further, Council continued to the Regular Meeting of
February 20, 1985, consideration of establishing a 4 -way stop
at Stockton Street and Pine Street
