HomeMy WebLinkAboutAgenda Report - January 20, 1999 H-03AGENDA TITLE: Report on Evergreen Drive at Elm Street Intersection Study
MEETING DATE: January 20, 1999
PREPARED BY: Public Works Director
RECOMMENDED ACTION: No action. Information only.
BACKGROUND INFORMATION: The intersection of Evergreen Drive and Elm Street has been
studied based on concerns received related to traffic congestion
and pedestrian safety.
The intersection of Evergreen Drive and Elm Street is a "T" intersection, with Elm Street terminating at
Evergreen Drive (Exhibit A). Elm Street traffic is controlled by a stop sign and Evergreen Drive traffic is
not controlled. A marked crosswalk was installed across Elm Street and across the south leg of
Evergreen Drive in March of this year. Traffic volumes entering the intersection on Elm Street and
Evergreen Drive are 1,105 and 1,920 vehicles per day, respectively. These counts were performed on a
weekday and include the additional traffic generated at the park due to soccer practice. Available
accident records for the four-plus years from 1994 to the present indicate that there have been two
accidents at the intersection, both occurring in 1994. Both of these accidents were solo -vehicle
accidents occurring during daylight hours; the drivers failed to stop at the posted stop sign on Elm Street
at Evergreen Drive, striking the curb in front of the park. One of the drivers was intoxicated, and the
other was only 15 years old. Based on these accidents, a warning sign was installed at the west end of
Elm Street in May 1995. There have been no accidents at the intersection since that time.
Staff's field review of the area adjacent to the intersection of Evergreen Drive and Elm Street indicated
that high pedestrian activity and vehicle congestion problems occur primarily during sporting events at
Peterson Park. As this neighborhood park has no parking lot, parking demand in the adjacent residential
area is high, and there are a number of pedestrians crossing at various locations along Evergreen Drive.
Staff also observed that due to the congested conditions, vehicles were traveling very slowly and drivers
were yielding to the pedestrians crossing the street.
STUDY RESULTS
The intersection of Evergreen Drive and Elm Street was reviewed for the installation of multi -way stop
controls. State of California Department of Transportation (Caltrans) guidelines are used when
considering the installation of multi -way stop controls. These guidelines consider traffic volumes,
accident history, and critical (85`h percentile) speeds. As indicated on Exhibit B, these guidelines are
not met.
Staff also considered other actions that would improve conditions at the intersection, such as driver and
pedestrian visibility. The visibility of drivers stopped on Elm Street at Evergreen Drive can be improved
by restricting parking adjacent to the intersection. Also, the removal of parking immediately adjacent to
the marked crosswalks will improve pedestrians' ability to see approaching vehicles, as well as the ability
of drivers to see pedestrians (Exhibit C).

RECOMMENDATION
Based on the relatively low traffic volumes, lack of an accident problem, and short congestion periods,
staff does not recommend the installation of multi -way stops at this intersection. A multi -way stop
control is also likely to lengthen the period of congestion by increasing the time it takes drivers to make
drop offs and pick ups because all vehicles will be required to stop at the intersection. However, we do
feel that restricting parking in some areas will enhance safety during the congested periods without
affecting traffic flow at other times of the day. Based on these factors, we will be installing no -parking
zones adjacent to the intersection and marked crosswalks as previously described and shown on
Exhibit C. Per Section 10.44.020(F) of the Traffic Ordinance, the Public Works Director has the authority
to install lengths of no -parking zones up to 20 feet without Council approval; therefore, no City Council
action is needed.
As an additional measure to reduce parking congestion and aid pedestrian safety during sporting events,
Council may wish to consider expanding the small paved area at the north end of the park to provide an
on-site parking lot. As shown on Exhibit D, a parking lot can be accommodated within the area between
the fence and Evergreen Drive. The example shown, utilizing the existing driveway for the pump station,
provides twenty-five parking stalls. The lot will require the relocation of some picnic tables and immature
trees. If the addition of a parking lot is going to be considered, it should either be constructed while the
immature trees can still be moved or the trees should be moved now to accommodate the future lot. A
more detailed layout and cost estimate can be prepared for presentation at a future meeting at Council's
request.
FUNDING: Funding for the installation of no -parking zones adjacent to the crosswalks from the
Street Maintenance Account at an approximate cost of $100.

BY: R. Kiriu
Any of the following conditions may warrant a multi -way STOP sign installation.

can be installed quickly to control traffic while arrangements are being made for the signal installation.
Satisfied Not Satisfied X
2. An accident problem, as indicated by five or more reported accidents of a type susceptible of correction
by a multi -way stop installation in a 12 -month period. Types of accidents susceptible of correction
include right angle and left turn collisions.

1.
A four-way STOP sign installation is a useful traffic control measure when other available means of
control are not adequate. It should not be used unless the volume of traffic on the intersecting roads
is about equal and is undesirable at low volume intersections.
