This map visualizes the 2013 pavement condition for local streets within each jurisdiction in the San Francisco Bay Area, as retrieved from MTC’s StreetSaver® database. Pavement condition is represented by the Pavement Condition Index, which was developed by the US Army Corps of Engineers, ranges from a like-new condition of 100 to a failed condition of 0. The average PCI in the San Francisco Bay Area is 66. Pavement deterioration is primarily caused by distress from vehicle weight and aggravated by weather conditions.
Local funding priorities also play a significant role in the condition of a road network. As an example, El Cerrito recently passed a “self-help” tax specifically for road and pavement preservation. As a result, nearly all of the road segments within the city limits are either in Excellent or Very Good Condition. In other areas, targeted improvements can stretch limited funds. The cities of Orinda recently passed funding measures for their street network and started by focusing on arterial streets. This ensures that although their very low traffic volume local roads have not been restored, nearly everyone in the community is able to immediately see benefits from their funding choice.
