It’s boom time in San Francisco, and it seems as though there’s more construction happening now than ever before. All over town, construction crews are busy building homes, hospitals and office towers to accommodate an impressive influx of new residents and businesses. Last Summer, Curbed mapped forty of San Francisco’s most prominent development projects. Since then, ground has been broken on a slew of hotly-anticipated towers, while construction has wrapped up on some staples from the old list. As such, it’s high time for a map update. See a project that deserves to be on the list, but hasn’t been featured? Drop us a line, or let us know in the comments. Here now, without further ado, an updated map of SF’s forty most notable active development sites.
