Are there kids playing on that sidewalk who might be exposed?

It's likely the local Councilmember will have to be convinced to lobby for the construction of the missing curb there... :-(

Dear Sir or Madam,

Thank you for contacting the Department of Public Works, unfortunately city planted trees on private property, planter strip, is the responsibility of the home owner and not Public Works. If you have any question please contact us at (510) 615-5566.

Thank you
