(CNN) A group of San Francisco neighbors came up with their own solution after they said the city wouldn't help them with the local homeless and drug dealer population, according to CNN affiliate KGO: They put boulders on the sidewalks.

The group has been going to city meetings and filing reports with the city for six months, according to KGO, but they haven't had any luck.

"It got to the point where everybody was just done," the person told KGO. "People had knives and guns and people were out fighting, carrying on and waking up people in the neighborhood."
