Thank you.

Nothing has been touched.

By there so called referral to code enforcement PWD considers this a private property issue. The fronting property owners are responsible for the maintenance and repair of there sidewalks.

Still nothing! I am waiting for someone to be impaled on the metal sticking up.

Still nothing done.

Nothing - waiting for someone get impaled on this. Where is the city inspector?

PWD call center will not do anything. It is up to you and your concerned neighbors to file complaints with code enforcement 238-3381. It take a week for an inspector to come out and then they have to give the property owners 30 days to respond. If nothing has happen after 6 weeks you will need to call back.

Thanks for the advice.

As per David Coleman's suggestion I called the city and they acknowledged the call and had an inspector here within two days.
