San Francisco Bay Trail - Fieldwork Results

About the Bay Trail The San Francisco Bay Trail is an interconnected system of on- and off-street trails circumnavigating San Francisco and San Pablo Bays. The ultimate vision for the Bay Trail is a continuous, 500-mile trail around San Francisco and San Pablo Bays serving 47 cities in all nine Bay Area counties. As of 2024, 352 miles (70%) of the 500-mile vision have been constructed. The Bay Trail welcomes a variety of users including people who walk, bike, and roll. It is intended to be used for many purposes including recreation, commuting to work and school, running errands, accessing transit, and visiting friends and family. **The Open Data viewer is intended for general display of features and is not appropriate for feature exploration.

Some segments were not ridden during the fieldwork inventory, including on-street sections of the Bay Trail and off-street sections designated as existing after the fieldwork inventory was completed. Data collected includes information on: Paved/unpaved status Shoulder presence Bollards/trail obstructions Narrow trail/pinch points Maintenance needs Poor pavement quality Missing curb ramps Wayfinding signs Otherwise substandard segments, per Bay Trail Design Standards Trail segments are split into roughly 250 foot subsegments. The following scores are calculated for each subsegment: Pavement Condition Index. Indicates the number of poor pavement quality deficiencies identified along the subsegment. Trail Quality Score. Indicates the total number of deficiencies identified along the subsegment. This includes bollards/trail obstructions, narrow trail/pinch points, maintenance needs, poor pavement quality, missing curb ramps, and substandard segment tags.

History Senate Bill 100, authored by then-state Senator Bill Lockyer and passed into law in 1987, directed the Association of Bay Area Governments (ABAG) to develop a plan for this regional trail system including a specific alignment for the Bay Trail. The Metropolitan Transportation Commission works with ABAG to implement the Bay Trail Plan, adopted by ABAG in July 1989. It includes a proposed alignment; a set of policies to guide the future selection, design, and construction of routes; and strategies for implementation and financing. Since its inception, the Bay Trail Plan has enjoyed widespread support in the region.
