Bury Utilities by the Coast?

As chair of Scenic & Historic Corridor Management Council and President of A1A Scenic & Historic Coastal Byway, I am frequently asked about burying utilities along our scenic highway. We get push back from Florida Power and Light (FPL). So in an effort to once again understand this issue, I went to FPL's website and found:

FPL maintains, "The reliability of overhead and underground lines is comparable...The key difference between underground and overhead lines is that it typically takes more time with underground lines to diagnose the problem and make repairs. This difference in repair time is best characterized in days rather than hours." Additionally FPL states on their website: "Compared to overhead transmission lines, underground transmission lines take longer to repair and are five to fifteen times more costly to construct...FPL may only bury lines when another entity agrees to pick up the differential cost between underground and overhead construction."

Doing some quick research on the Internet, I found this report that states that underground lines are considerably more reliable than overhead, but again more expensive to bury. So, as we all suspected, it comes down to money.

In the above Edison Electric report, on page 11 it says, "The Florida House of Representatives requested that the Florida Public Utility Commission prepare a proposal to underground all electric facilities in the state following the unprecedented landfall of four major hurricanes in Florida in 2004."

We need to find the referenced proposal. I found it:
