When driving down the road, there are often road destruction signs stating that the left lane is closed, but usually the right lane is the one closed, or the opposite of whatever the sign states.
In the case of that neighborhood, the road used to make a big U. Parking was on the left, driving on the right. People used this street as a shortcut, going both ways, so the one way and DO NOT ENTER signs were placed. No change, so a small dog park was built at the base of the U, thus closing off the street, or so the thought was, but people drove over the (accessible) curb, through the park. So, barrier poles were added. The residents refused to have reflective signs placed, and people were crashing into the barriers. Wrecked cars were difficult to remove, and blocked the street--often for days. From then on, cars in violation have been ticketed and towed. I suppose they could be ticketed for blocking traffic, parking in the driving lane, or any number of things. The street was never striped differently, and the city still lists the street as 1-way.
Gated communities pay a FORTUNE for their streets. The only good way to handle the streets is to have one of the residents actually do the street repairs, cleaning, etc. Then there's the trash pickup issues, yard waste disposals, etc. The other residents need to be the mayor, a councilman, the chief of police, the towing company operator, and the judge. There is a reason we call them ”sewed up communities”.
