The issue of micro-trenching came up again in my brain, so I decided to inquire via my district supervisor (I live in the Mission on a block with buried lines). I got this response from the city:
I'm so happy to hear this is actually moving forward, and that Sonic is working with the city on a path forward. I hope to get this service ordered from Sonic the moment it's possible.Per PW's Infrastructure Design and Construction team, with the passage of Senate Bill SB378, we have developed draft microtrenching standard plans. Sonic Telecom has contacted us and has provided their input on draft standards. We have not yet finalized the standard plans as Sonic is clarifying a few issues with the California Public Utilities Commission, CPUC. We are waiting to hear back from Sonic and their discussion with the CPUC. We will allow microtrenching in order to comply with SB378, but will need to have an approved standard in place before allowing mircotrenching.
