20th Avenue Traffic Calming Project
This project was made possible through the efforts of Supervisor Chu.
Local residents have expressed their concerns regarding speeding and cut-through traffic on 20th Avenue between Taraval and Ulloa Streets. The Traffic Calming Program monitored speeds, which exceed 30 mph in the downhill direction. While some motorists use 20th Avenue to avoid red lights on 19th Avenue, many others must use 20th Avenue for local access to parts of Parkside and West Portal. Regardless, their speeds ought to reflect the fact that they are travelling through a residential neighborhood, not a designated arterial. This section of 20th Avenue is 46 feet wide and a designated bicycle route. It has a prima facie speed limit of 25 mph.
The angled parking near Taraval Street was installed and midblock island were approved by a ballot of nearby residents and have been installed. The proposed pedestrian island at Ulloa Street and the midblock bulb-out were rejected by a ballot of the residents. Evaluation of the effectiveness of the midblock island should be completed by June, 2011.
