3. An Edison street light located on the north-east corner of the
subject intersection is currently not operating.
Regarding ItemNumber 1 above, the Engineering Division will
continue to monitor the traffic control for this project to ensure
compliance with the approved Traffic Control Plan.

well as 250 watt lamps in safety lights at intersections throughout
the City. The existing flanged bell-type
intersection are no longer used by the City in g new ore subject
replace
installations of safety lights - the cobra -head type are currently
installed at new or replaced locations. The flanged bell -type of
housing tends to direct the light in a more focused downward
direction rather than in the more dispersed fashion of the cobra -
head.
The Engineering Division is currently reviewing the safety lighting
at this intersection and investigating the possible installation of
four new cobra -type safety lighting heads with 250 watt lamps.
This would increase the total lighting at the intersection.
Regarding Item Number 3 above, staff has already contacted So
