What to Do About Gang Violence in Salinas California

Is there any connection between the fact that Salinas has the gang problem that it does, and the fact that Monterey County's restrictions on the building of housing are very strict? I can see why the inhabitants of the Monterey Peninsula might want to protect the coastal strip. But if they apply their policies to the whole county, it becomes very difficult to build any housing. I saw a proposal 40 years ago from Ralph Nader's think tank that would encourage the building of Italian style hill towns along the hills along both sides of the South Santa Clara Valley, thus leaving the lowlands along the river for agriculture; such a plan could be applied to the Salinas Valley as well. I don't have the expertise to draw the connection between restricted housing and the gang situation in Salinas, but surely the situation is worth looking at. What kind of novels would a John Steinbeck write, if he were growing up in Salinas today?
