IT TITLE: Ordinance - Iq9 ~ Establishing
speed limits on Telegraph Canyon Road between
Interstate 805 and Old Telegraph Canyon Road (the
access road to Ar hway Inn) SECOND READING AND AD(3#'T,~f
SU ITTED BY: City Engineer (4/Sths Vote: Yes No x )
In response to the Council referral of a traffic hazard at the
me ian opening to Canyon Plaza Shopping Center on July 18, 1981
an a request from the Police Department, the Traffic Engineer
in estigated the current speed limit on Telegraph Canyon Road
bet een Interstate 805 and Old Telegraph Canyon Road (access road
to Arch way Inn). As a result of these investigations, lower
spe d limits were posted as a trial traffic reg ulation. Coupled
wi h this, the Police have increased the enforcement of the
pos ed speed limits along this segment of Telegraph Canyon Road.
The a trial traffic regulations have been functioning as intended
for one year. Therefore it is my
RE OMMENDATION: That Council adopt this ordinance establishing a
35 ph speed limit on Telegraph Canyon Road between Interstate
805 and Oleander Avenue and a 45 mph speed limit between Oleander
• Ave ue and Old Telegraph Canyon Road (access to Archway Inn).
BO D/COMMISSION RECOMMENDATION: The Safety Commission voted 5-0
on February 11, 1982, to recommend that these speed limits be
mad permanent.
DISCUSSION:
With the construction of Telegraph Canyon Road between Interstate
805 and Oleander Avenue and the opening of the shopping center
along the north side of Telegraph Canyon Road, there was a
significant increase in the number of accidents at the median
opening to the shopping center entrance and at the Halecrest
Dri e traffic signal.
In May of 1981, two segments of Telegraph Canyon Road were
sur eyed and the following trial speed limits were posted:

axpected, the posting of a lower speed limit did not change
85th percentile speed. The posting of a lower speed limit is
opriate, however, for the following reasons:
This segment of Telegraph Canyon Road is transitioning from
a high speed rural road to a urban arterial street. The 35
mile per hour speed limit matches the speed limit on
Telegraph Canyon Road/"L" Street to the west.
A higher westbound approach speed to the I-805 and Halecrest
Drive traffic signals increases the potential for rear end
accidents. Because these signals are so close together, the
signals at I-805 are designed with limited visibility
programmed heads for traffic approaching from the east.
This reduces the potential for drivers mistaking the traffic
signals at the I-805 freeway for the Halecrest Drive
signals. This limited visibility increases the rear end
accident potential for higher speed traffic.
The nature of adjacent land use is changing on this segment
of Telegraph Canyon Road. The presence of a shopping center
and apartments has increased the potential for conflicts
between pedestrians and vehicles entering/exiting driveways.
Telegraph Canyon Road east of Paseo Del Rey has limited
access control - therefore higher speeds are permissable.
;AL IMPACT: The cost of posting this trial traffic reg ulation
approximately $400.
