That green swath (or flowered patch or hardscaped segment) is truly the city's. But, be that the case or not, the home owner feels he/she has a vested interest in shooing pooing pooches as they seek to mark the parkway. As with all things urban the best defense is common sense. Not many neighbors would applaud an owner and pet doing their business amid an oasis of blooms though it be on the parkway. Nor are goldstars given to the militant ones whose walks are not deterred by areas newly seeded for grass to be. By the same token, precious little empathy is expressed for the vein-throbbing overseers with anti-dog agendas. One thing sure to be received well should you ambulate with a female dog - carry a water bottle on the journey and freely dowse her peed-upon area to alleviate the "burn" her high nitrogen content urine tends to leave. These marks are frowned upon by most who see them.
Happy trails to you,

As the previous answers stated the parkway is city property, however the home owner is responsible for maintaining this area.
While I realize this doesn't apply to everyone, I have found good luck in respectfully asking dog owners to not allow their dogs to eliminate in the parkway in front of my house. If you have a good reason such as your children playing there let them know. In my experience dog owners would rather go ahead and walk a couple doors down than upset a neighbor.
Best of Luck with your situation.

In many communities there is a pooper scooper law that requires you to pick up your dog's poop. If caught not doing so, there is a fine.
Good luck to all of us home owners.
