INFORMATION REPORT - ~IN Sll~EET MEDIAN ISLAND INSTALLATION
RECOMMENDED ACTION:
For the City Council meeting of September 2, 1986.
Pleasure of the City Council.
BACKGROUND:
At a previous City Council meeting, staff was requested to review the possibility
of installing raised median islands along Main Street between "B" Street and
Myrtle Avenue. It is assumed that the raised median islands would accommodate
landscaping similar to the areas throughout the City.
DISCUSSION:
The widths of Main Street between "B" Street and Myrtle Avenue vary from 53.3 feet
to 60 feet in width between curbs. This minimum width would accommodate the
following:
° Twelve foot wide landscaped median
° One 12 foot wide (minimum) travel lane in each direction
o XOne 8 foot wide parking lane on each side of the street
This configuration would 'be similar to the painted pavement markings which
currently exist.
In the event raised median islands were to be utilized along Main Street,
would recommend the following:
Continuous medians with openings only at street intersections.
This would eliminate any cross turning movements into or out. of
private driveways and could provide an inconvenience to the
residents.
2. Consideration of extending the median islands easterly to "C"
Street and westerly approximately 200-300 feet.
Installation of median islands at the same time Main Street is
reconstructed as an Orange County Unified Transportation Trust Fund
(OCUTT) project.

PAGE TWO
Median island installation has both advantages and disadvantages to the Main
Street area.
Disadvantages
Restricts number of travel lanes 1.
in each direction without future
widening/curb relocation.
2. Inconvenience to resident with 2.
regards to access to their
pcoperties.
Prohibition of U-turns at street
intersections due to narrow width
of street.
Increased cost for landscape
maintenance.
Advantages
Beautification of neighborhood
from additional landscaping.
Controlled access for cross
traffic. Elimination of cross
traffic into residential driveways.
If the City Council desires to pursue this matter further, staff will provide an
estimate of both construction cost and annual maintenance cost.
