That the Tustin City Council approve alternative No. 3 and authorize the
installation of fifteen conventional style marbelite street lights along Main
Street between "C" Street and SR -55.
BACKGROUND:
In October, 1988 the City Council 'authorized staff to proceed with the
installation of ornamental street lighting along Main Street between "C" Street
and Pacific Street. The selected style of ornamental lighting was the
Washington Post style standard with dual luminaires as pictured in the attached
drawing. At that time the selected style was only manufactured by a private
firm and consisted of a black cast iron standard with dual luminaires. This
style of light would be a City owned and maintained system which would be
totally different than the remaining street light system within the City which
are owned and maintained by the Edison Company for a monthly fee.
In late 1988, the Edison Company
supplying an ornamental street light
Company at this time has developed a
a black prestressed concrete standard
unit.
DISCUSSION:
expressed an interest in manufacturing and
of the Washington Post style. Edison

The original Main Street reconstruction project between "C" Street and Pacific
Street would require the installation of ten (10) new street light standards
and the exchange of one (1) existing light standard to the new ornamental type
light standards for a total of eleven (11) new ornamental units.
The second segment of Main Street improvements between Pacific Street and SR -55
freeway would require the installation of five (5) new street light standards
and the exchange of four (4) existing light standards to the new ornamental
type units for a total of nine (9) new ornamental units.
The following is a recap of the estimated costs for the installation of
ornamental street lighting along Main Street:

Currently the City has budgeted $27,600 for ornamental street light
installations along Main Street between "C" Street and Pacific Street in the
1989-90 Capital Improvement Budget. ,
Following are three alternatives related to the street light installations
along Main Street:
1. Install eleven Washington Post style street lights between "C" Street
and Pacific Street as previously authorized and five conventional
style marbelite street lights between Pacific Street and S.R.-55 at, a
total estimated cost of $46,914. This would require a supplemental
1989-90 budget appropriation of $19,314.
2. Install twenty Washington Post style street lights between "C" Street
and S.R.-55 at a total estimated cost of $77,080. This would require
a supplemental 1989-90 budget appropriation of $49,480.

3. Install fifteen conventional marbelite street light standards between
"C" Street and S.R.-55 freeway at a total estimated cost of $13,560.
No supplemental budget appropriation is required for this alternative.
A $14,000 savings could be achieved with this alternate.
Staff recommends that street lights be installed along the entire length.of
Main Street between "C" Street and S.R.-55 regardless of which alternative is
selected, so that adequate lighting can be provided for improved pedestrian and
traffic safety.
