We are currently expanding our reach in SF, and I saw a meeting outline for later this week with our development group to discuss another significant build there. We also have a lot of infill in our pipeline, for areas in SF where we could not reach due to unsafe poles, where that issue has now been resolved and we can finally deploy. (Hopefully, your location is in this category.)
But even with these projects, SF will always have inconsistent coverage because the City does not currently have standards that allow new utilities to place conduit using modern trenchless construction methods. Without these methods, widely used elsewhere, both boring and microtrenching, it just is not possible for any utility that does not already have a conduit to every home to build infrastructure there. We remain very interested in achieving uniform coverage in SF, but their standards will need to be updated. Perhaps tell your Supervisor that you want more than two choices for internet access someday.
