The United States Postal Service is seeking a site for a long-term post office in Bolinas after it rejected the latest citizen-led plans for a temporary site earlier this month. The community group twice submitted plans for a prefabricated building at Mesa Park, but the postal service rejected them, first citing size deficiencies and later saying that a temporary post office was simply not feasible. Aenor Sawyer, a member of the group spearheading the effort to return postal service to town, said the postal service is looking for available property, but that establishing a new office could take as many as five years. “None of these plans are immediate, but some are more short-term achievable than others,” she said. Ms. Sawyer said the postal service had been a difficult partner, despite her group having the support of government officials like Rep. Jared Huffman. “They shut down the working group between us and Huffman’s office,” she said. “Since then, we’ve had a very tough time getting in touch with them.” The post office debacle began in February after a landlord-tenant dispute over asbestos forced the office out of its Brighton Avenue location. A committee of Bolinas residents, activists and architects soon began to devise an interim solution. A postal service team approved a temporary plan for Mesa Park, but the service abruptly put it on hold and then rejected it due to previously undisclosed square footage deficiencies, said Bolinas resident John Borg. After the group changed the square footage and resubmitted the project, the plan was rejected again. This time the service said an interim office was not possible. “They’re just moving the goalpost,” he said. “We don’t get any feedback until we’re inches from getting a lease. It’s like pulling teeth to get information. It seems like we’re blocked at every step, and it’s hidden in this opaque bureaucratic bubble that is really difficult to pierce. But we’re not going to cave and give up; we’re going to keep pushing. We want to work with them to establish a long-term plan.” Since October, Bolinas residents have had to pick up their mail from the Olema Post Office, which floods during heavy rains and has no public transportation from Bolinas. Before that, mail had been delivered to the Stinson Beach office, an easier location for many, advocates said. “We’ve lost so much ground by being shunted there,” Ms. Sawyer said. “With Stinson, there was wall space for boxes and public transit. It’s mind-boggling that they didn’t listen to what the town needed. It just seems to get worse and worse.”
