SFCTA Congestion Pricing Study

The San Francisco County Transportation Authority (SFCTA) is exploring congestion pricing in San Francisco. This would impose a fee to all motorists crossing into the downtown San Francisco area from Van Ness, Laguna, Fulton, Division, 14th St., Mariposa St., and from the Bay Bridge. The proposed fee would be between $7-$14 for each trip and is intended to reduce traffic congestion by 15% of pre-pandemic levels in select areas of San Francisco. This directly affects anyone who lives, works, or runs a neighborhood business in these boundaries. Service providers (including ride-hail), vendors, or commercial vehicles will also be charged.

More study and public comment is needed!  This project has the potential to fundamentally impact businesses, commuters, and residents traveling to SF’s Downtown Area and residents who need to traverse The City.

Please click here to review SFMTA’s quick factsheet about the Congestion Pricing Study. You can also visit the SFCTA Downtown Congestions Pricing Page here for more information.

Bees At Work

100 First is excited to be the home to a honey bee hive! Located on the Sun Terrace in a locked location, the bees are buzzing and producing honey. We are happy to provide a home for local honey to be produced with plant and flower nectar collected in the neighboring areas.

Urban beekeeping creates the opportunity to educate citizens about the environment, repurpose unused spaces within our cities, and produce hyper-local honey.

We invite you to visit our hive’s very own webpage here to follow along for live updates on our bees traveling through the neighborhood.
