I'll give the landscaper the benefit of a doubt and say the sprinkler was there first.

Electricians placed the box per the plan, which was drawn at the office, and no one noticed the sprinkler. It's an easy fix, though.

water cooled transformer, fancy

Yeah, like corpos do any better. Fuck off with this shit

The landscaping department is just conducting an IPx5 water ingress test!

How do you think the sprinklers get power?

Dont worry it's IP67

Those sprinkler heads can be re-pointed.

Regulations

I believe your complaints should be aimed at public works as they're the ones who did this - if indeed that sprinkler head is on city/county/state property.

Parks and recreation most likely.
