Reference Request # 1251920, originally filed August 2014, for this same issue that still has not been addressed.

Thanks for Reporting! In most cases the sidewalk is the responsibility of the homeowner, in accordance with City Municipal Code Title 10 (you can read the Code here: http://bit.ly/11cZkdr). If you would like more information or have questions/concerns regarding this, please feel free to call our Streets section at 707-648-4430.

Thanks for fixing this request!

Interesting. I never knew that, and I suspect others don't either.
So, pursuant to section you referenced and linked, will you be notifying the affected property owners of the necessary repairs needed?

Also, interesting enough, when I first reported this matter in 2014 (request # 1251920), the City did not respond with this information, and did not repair it.
