How are these private signs legal?

"Caution Children Playing" sign looks like it was badly bent out of shape by some children playing.

Today is day 43, I am beginning to fear my comrades at public works have all but forgotten about me. The neighborhood children have finally accepted me as one of their own, but they know I have come from somewhere else. I long for the day that the other cones work together to bring me home!

Manhole cover coming off so opening partly exposed and may be broken. Previously reported by phone but never repaired.

50 cm pothole in middle of street. About 10 cm deep. Please fix.

Cracks everywhere. Super dangerous for skateboarders and bikers

Potholes and road is uneven

The property to the south (adjoining vacant lot) has severely broken sidewalk for about 15 feet and around half the width. There is a 2 inch heave on one side and one crack is large enough to put a hand inside the gap.
Please take a look. A cement patch could fill in the hole and in in the spring, the sidewalk could be repaired.
I would not recommend a city sidewalk plow towing a sander trailer drive over that section.

There has been a construction cone sitting in the middle of the road for at least 1-2 months.

There has been a constitution cone sitting in the middle of the road for quite a while. it causes multiple issues with circulation as cars are forced to go into the other lane to go around the cone.

Some kind of valve on the street looks broken. Appears to be a water shut-off valve.
