Alley Maintenance

I just ran across this link from the city of Seattle
http://www.seattle.gov/transportation/alleys.htm

The city states 'Property owners are responsible for alleys next to their property. (Alleys are defined as any unopened street areas next to their property.'

I guess I assumed this, but it is nice to get confirmation that this is actually the law. Keep in mind however that most of the dumping that I list on this site is actually on AM/PM's property, not just in the alley behind their property.

Keep in mind also that they own a dumpster, it would only take them a few minutes a week to maintain their property and the public access next to their property, but they still refuse to do this.
