I was able to get a copy of the homes in my block that had the dimensions of each property (it came from the city from the recent plaza proposal built down the street).
I was able to find the reference points in front of my house. The reference markers have an "edged" on the walkway. My neighbor across the street helped me located them.
I am going to run a string to each side of the dimension to find my property line on the back.
