These department codes are maintained in the City's financial system of record. Department Groups, Divisions, Sections, Units, Sub Units and Departments are nested in the dataset from left to right. Each nested unit has both a code and an associated name.

The dataset represents a flattened tree (hierarchy) so that each leaf on the tree has it's own row. Thus certain rows will have repeated codes across columns.

Data changes as needed.

A list of officially valid street names contained in the City's GIS Basemap

A. SUMMARY
This dataset is derived from parcels and several other overlay administrative boundaries (listed below). The dataset was developed by DataSF as a convenience for matching parcels to districts where appropriate. This can be simpler than running a geospatial process every time you want to join parcels to a boundary. The districts provided here run along streets and are non-overlapping so that the parcels will be contained within a single district.

The boundaries included are:
1. Analysis Neighborhoods
2. Supervisor Districts
3. Police Districts
4. Planning Districts

B. HOW THE DATASET IS CREATED
A script runs daily that overlays parcels with each of the boundaries to produce the composite dataset.

C. UPDATE PROCESS
Updated daily by a script based on the upstream parcels dataset which is also updated daily.

D. HOW TO USE THIS DATASET
You can use this dataset to match to administrative districts provided here to datasets that contain a parcel number. This can be a simpler process than running these joins spatially.

In short, we pre-process the spatial overlays to make joins simpler and more performant.

All active addresses from the City's Enterprise Addressing System (EAS), including sub-addresses, such as units. Includes references to parcel and street centerline data (Note: not all addresses are associated with parcels). Updated nightly. See EAS Base Addresses for base addresses not including units.

Active base addresses from San Francisco's Enterprise Addressing System (EAS). This dataset does not include sub-addresses, such as units, and does not include a block/lot value for each record. For units and block/lot values, see the "Addresses with Units - Enterprise Addressing System" dataset.
Note: this dataset now includes as of 12/17/2020, base addresses that may not have any block/lot value associated.

A list of Street Segment and Intersection (CNN) changes including new, dropped, realigned, divided and split records.

A list of street segments and intersections sorted by street name and ascending address number. This data set is based on the City's GIS basemap and contains CNN id numbers for each record.
