Have you noticed any maintenance needs at the Panhandle? Potholed pathways, faded paint, broken sinks or toilets? The best way to request repair is through SF311. Today, stencils on the pedestrian path near Shrader were repainted, perhaps the result of a resident's request.
I find it really easy to contact SF311 through Twitter. Everyone can see my 311 requests pertaining to the park by searching "@4thepanhandle @sf311" on Twitter.
