New York-based sandcastle artist Calvin Seibert (previously featured here) recently traveled to Hawaii where he created more of his awesome abstract, geometric sandcastles. They’re an impressive and tantalizing distraction for those of us still surrounded by wintry weather.

This is an interesting renewal of an old plan, and while I have not researched it’s benefits fully, I am not fully sold on the idea as yet.
Twice, the power on my block in Russian Hill has been knocked out for upwards of 36-hours by car accidents that knocked out a utility pole nearby. This would definitely be a non-issue with underground utilities, so I see some value.
The city-wide effort to do this has been started and stopped multiple times due to cost overruns. Given the new fiscal climate we live in, I think it is unwise to spend the city’s funds on this effort unless it buys us other upgrades as well.
The coalition mentioned below does not provide a strong use case other than the argument that the cables mar the beauty of the city scape. Personally, I think they add character to the city scape, and link us to a recent past that includes the cable cars and Victorian architecture. Aesthetics and beauty are subjective, so I hate to see that as the core argument here.
This would be a worthwhile endeavor if the ongoing maintenance and upgrades are easier once complete, and if other advantages can be gained in reducing transmission loss, cable theft, upgrade to telephony infrastructure, etc. More importantly, this is an opportunity to create a new city infrastructure that can be shared with the private space for new benefits to the residents as well.
Given the state of Muni service today, this could either be a shot in the arm for them to upgrade their infrastructure and operations, or it would divert Muni funds to bus replacement, prior to other up improvements needed on the system, resulting in zero net-benefit to us city residents.
San Francisco’s Electric Bus Pollution ProblemThere are no emissions of pollutants or noise from these electric buses that receive power from overhead wires; but it’s the wires that are viewed by some as visual pollution. Powered from the city’s hydroelectric dam, they are truly carbon-free.
The electric trolley buses, dating back to 1935, may have more in common with the electric streetcars that plow Market Street and the Embarcadero in San Francisco than with new, battery-electric buses that are just entering the marketplace, e.g. New York. But for some, that day can’t come soon enough for San Francisco.
"It’s visual pollution," said Anne Brubaker, a founder of the San Francisco Coalition to Underground Utilities. “We’re living in what should be one of the most beautiful cities in the world, but you can’t see it for all the wires.”
For the record, “(t)rolley coaches (also known as ‘trolley buses’ or ‘trackless trolleys’) are rubber-tired vehicles with motors powered by electricity from overhead wires. ‘Trolley’ refers to the trolley poles on the roof of the bus that are used to transmit the electricity from the overhead wires,” according to the San Francisco Municipal Transportation Agency.
However, from Muni's perspective, it's not just a matter of being green for green's sake. Trolley buses offer advantages over the diesel-powered buses in the transit agency's fleet. San Francisco's famous hills, while scenic, pose major challenges to transit vehicles, as well as human-powered ones.
"You have to ask whether the visual pollution is more important than the operational advantages of the trolleys," said John Haley, director of transit for the San Francisco Municipal Transportation Agency. “For example, it’s impossible for buses to get up the grade of California Street.”
Supervisor Scott Weiner offered first-hand testimony to that effect.
I take the 24 (Divisadero) line, and sometimes Muni has to use a regular bus on the route,” Weiner said. “There are times when that bus can barely make it up the hills.”
John Wildermuth writes that “San Francisco is one of the few cities in the country that still uses electric trolleys, joined by Seattle, Boston, Philadelphia and Dayton, Ohio. Muni’s fleet of 311 trolleys (out of about 1,100 total transit vehicles) is the nation’s largest.”
Ultimately, it may come down to "the visual pollution versus the measurable and real pollution from even the cleanest of diesel vehicles," as SFMTA’s Haley put it. Throw in operational superiority, on hills at least, and the San Francisco Coalition to Underground Utilities might want to stick with power lines, not overhead wire for the city’s trolley buses, at least until battery-electric buses prove themselves.
