STREET IMPROVEMENTS
The past year was noteworthy for the number of street improvements
on major traffic lanes requiring changes on important trunk lines. Among
them were:
The old 30 inch riveted steel line on the hillside above Riverside
Drive from the High Bridge at Fletcher Drive to the Dayton Avenue
Bridge was replaced by a 40 inch line in Riverside Drive. The total
length of this trunk line was 12,330 feet, of which 2829 feet were 14 inch
riveted steel pipe and 9501 feet were 5/16 inch steel bell and spigot
pipe with automatic electrically welded longitudinal seams.
A fill with a maximum depth of 18 feet was made on Vermont
Avenue, between Fourth and Sixth Streets, requiring the temporary
removal of 1250 feet 30 inch Cast Iron, for a period of over eight months.
The construction of the First Street viaduct over the Los Angeles
River, made necessary the relocation of 197 feet of the 30 inch riveted
steel Santa Fe trunk line around the west abutment of the viaduct.
Approximately 60D feet of the 24 inch Cast Iron Garvanza Trunk
Line were lowered, due to improvement of Fletcher Drive westerly from
Avenue 36.
Another fill on Third Street, between Berendo Street and Kenmore
"I Avenue, necessitated the changing of the grade of the 27 inch riveted
line for a distance of 598 feet, requiring the installation of 465 feet of
reconditioned pipe.
Improvement of Glendale Boulevard was the cause of lowering 54
feet of the 30 inch high gravity trunk line on a private right-of-way
south of Waverly Drive.
It was necessary to lower 469 feet of 24 inch Cast Iron on Angeles
Mesa Drive southerly from Santa Barbara Avenue, due to reestablishment
of street grade.
In connection with the effect of street improvements on the work of
this Division, mention is made of 118,964 feet of pipe, mostly 1 inch and
2 inch, used for temporary side lines during the year,
Three other jobs of a similar nature must be done in the near future.
They are:
