Pole Life

27% of poles are over 60 yrs. old

Must replace >5,000 per year to

gradually reduce average age

Cable Life

4,500 miles of UG Distribution Cable

Replaced this year = 26 miles

Acceptable replacement rate = 60 miles/yr.

Fix-It Tickets

40,000+ repair orders backlogged

Target level is <5,000

Additional funding required to

decrease amount of backlog

Majority of poles installed during L.A.’s rapid growth (between 1940’s -1960’s)

At 5000 poles per year, it would take over 17+ years to replace poles currently 60+ years old

During that time, another 130,000+ poles will be 60+ years old, which would take another 26 years to replace.

Note: 60 years is estimated life. Actual life will vary.
