ITEM TITLE Report on the Installation of Left Turn Lanes on East "L"
Street Between Melrose and Nacion Avenues
SUBMITTED BY City Engi7neer via Director of Public Works 1
.~~/
ITEM EXPLANATION (4/5TH'S VOTE REQUIRED YES NO x )
In September, 1978, East "L" Street between Melrose and Monserate
Avenues was restriped to provide for left turn lanes at Melrose, Myra,
Maria and Monserate Avenues. East "L" Street is a major east-west
arterial street carrying 20,000 vehicles a day and there have been
many accidents occurring along this section during the past few years.
• We believed that the left turn lanes would reduce accidents and
stabilize the traffic flow on East "L" Street. It should be noted
that insufficient time has passed to adequately evaluate changes in
accident rates. However, our field observations indicate that the left
turn pockets are working satisfactorily.
Since the left turn lanes were installed, we have received several
• requests from residents on Monterey Court and Mission Avenue for action
to alleviate the access/egress problems for them to East "L" Street.
The problems result from limited sight distance due to the vertical
curve on East "L" Street between Melrose and Nacion Avenues and the
lack of a refuge area for vehicles turning from East "L" Street onto
l~lonterey Court, Mission Avenue and Nolan Way (see plat).
Residents were invited to Safety Commission meetings in December, 1978,
and January, 1979, to discuss alternative solutions with staff and
commissioners. The discussion included: the modification (lowering)
of the vertical curve to allow for better sight distance; installation
of a raised curb median to eliminate left turns; and installation of a
traffic signal to alternate vehicle right of way. However, it was
realized that these solutions would be very expensive and should be
considered for future Capital Improvement Programs (CIP), if necessary.

Supplemental Page Two
It was decided by staff and Safety Commission that the best, low cost
solution would be the continuation of the left turn lanes easterly from
rielrose Avenue to Nacion Avenue (see plat). This restriping would
provide primarily for a refuge area for vehicles turning left from
East "L" Street and secondarily a partial refuge for vehicles turning left
onto East "L" Street. Traffic Engineering staff recommends this
alternative be used and evaluated for a 12-month period. After the
12-month period, further action or a more expensive alternative may be
recommended.
The provisions of the left turn lanes necessitates removal of on-street
parking between Monterey Court and Nolan Way. Although there are
four residences which front on East "L" Street in this segment, the
• parking survey conducted prior to installation of left turn lanes
last September, indicated that there was very little on-street parking.
(During the week long survey, one vehicle was noted in front of one
of these residences at one observation. Twenty separate observations
were made during the survey.) The residents who would lose parking
adjacent to their property have been notified by mail that the City
Council will consider this matter on February 6, 1979.
