I do not know that preventing parking on cul-de-sacs is going to help.
I live on a cul-de-sac where nobody parks and the plow still doesn't get anywhere near the curb in the winter. The pile last year reached from the fire hydrant -- 2 feet from the curb -- to 10 feet into the circle.
The garbage trucks were having a terrible time turning around. I was afraid of what would happen if an ambulance or fire truck would need to come. It would also have been difficult to get a hose from the hydrant to any house except ours.
I hired a construction company to come with a dump truck and a skid loader. They hauled away nine full truck loads from the edges of the circle to the curb. It cost $800. The city hauled the snow away from the curbs at the other end of the street but not the cul-de-sac.
