because los angeles is older than most other cities in california, the ladwp is currently faced with several unique issues. most of the power lines in los angeles were built above-ground before it became customary to run power lines below-ground. starting in 2007, ladwp has a long-term project to upgrade the overhead power lines and convert them to underground. this difficult conversion has been slowed by budget constraints, the impact on traffic, the pursuit of other modernization projects, and the lingering effects of a workforce reduction over the last decade. budget issues are particularly acute in the department's transmission system, where underground transmission costs about 10 to 14 times the cost of overhead transmission, per unit length, and the technical and environmental challenges which confront such installations. additionally, undergrounding of the three 500 kv transmission lines (five lines, if the pacific ac intertie's two 500 kv lines terminating in los angeles are included) is presently technically infeasible. upgrading the overhead lines is expected to take 10 to 15 years. the upgrading of ladwp's overhead power lines consists of eliminating the v-shape brackets on the power poles that are holding up the crossarm and replacing them with cross-brackets that are put on the crossarm. some of the wooden power poles are being replaced with metal poles. also included in the upgrade of overhead power lines, are the upgrades of the insulators for the lower voltage distribution power lines, which are more modern than the old-fashioned ceramic insulators. the new modern insulators for lower voltage distribution lines look identical to southern california edison's distribution insulators.
