Speed Limits per Street Segment
A. SUMMARY Maximum speed limits per street segment for the City of San Francisco. Speed limits are indicated primarily for streets that have speeds greater than 25 MPH, unless the speed limit has been changed from a higher speed or a speed survey has been conducted to enforce the de facto speed limit of 25 MPH. 25 MPH is the de fact speed limit for most residential and commercial streets, and apply to streets on this map denoted by a 0 MPH label. Alleys narrower than 25 feet can have de facto speed limits of 15 MPH. B. METHODOLOGY Speed limit legislation information is taken from MTAB legislation and in some cases directives from engineers in the 5212 classification. Speed limit implementation information is taken from SSD Shops Reports and then parsed via python code. Implementation for speed limits will specify when signs are put in stating the new speed limits, and the work order that the sign installation was spec'd in. C. UPDATE FREQUENCY Updated quarterly or on an as need basis by request

For deployment status of new services beginning in February 2025, see https://gis.data.ca.gov/pages/city-and-county-boundary-data-status. Additional roadmap and status links at the bottom of this metadata.,Purpose City boundaries along with third party identifiers used to join in external data. Boundaries are from the California Department of Tax and Fee Administration (CDTFA). These boundaries are the best available statewide data source in that CDTFA receives changes in incorporation and boundary lines from the Board of Equalization, who receives them from local jurisdictions for tax purposes. Boundary accuracy is *not* guaranteed, and though CDTFA works to align boundaries based on historical records and local changes, errors will exist. If you require a legal assessment of boundary location, contact a licensed surveyor.,This dataset joins in multiple attributes and identifiers from the US Census Bureau and Board on Geographic Names to facilitate adding additional third party data sources. In addition, we attach attributes of our own to ease and reduce common processing needs and questions. Finally, coastal buffers are separated into separate polygons, leaving the land-based portions of jurisdictions and coastal buffers in adjacent polygons.
