Well, good to see a response and position statement from public works.
Of course, I'd argue the opposite: the complexity and congestion of the existing underground space makes microtrenching an ideal solution for new infrastructure deployment. It's used in New York City and Chicago for example - similarly complex and dense environments.
I contacted Supervisor Mandelman's office back in October 2019 about micro trenching in SF but didn't get anything other than a "we'll look into it."
Dane, do you see any forthcoming solutions to those of us stuck in areas that can't get fiber? Are there 5G or other potential solutions? Even my x2 DSL is ending up insufficient when games are 120 GB+ to download. I know 5G is over-hyped, but it seems like it actually may have some high bandwidth applications in an environment like SF.
