After publication of our post “Dear City, Turn on the lights in Cedar Park” a number of readers commented about their experience with submitting maintenance requests via 311 phone, online or Twitter service. But if you own a smartphone, one reader, Andy L., recommended downloading the new Philly 311 mobile app. The app came out just a few months ago and works great.

“It lets you upload photos and gives you status updates until it’s done. I just started using it, and it’s working for me. For best response, try to pick the right category, like graffiti, or dumping, or problem with a vacant property, abandoned car, etc.,” Andy L. recommends.
