In other parts of the city, there are parking signs limiting when cars can be parked in certain neighborhoods (i.e. parking from 8AM - 6PM only; No Parking without permit after 6PM, etc.) In my neighborhood (Washington/Redondo), there are random cars on our streets at all hours of the day and night. The only restriction is during street cleaning. My neighborhood would definitely be safer if parking were limited to residents only. How do I attempt this kind of change?
