The Integrated Library System (ILS) is composed of bibliographic records including inventoried items, and patron records including circulation data.
The data is used in the daily operation of the library, including circulation, online public catalog, cataloging, acquisitions, collection development, processing, and serials control.
This dataset represents the usage of inventoried items by active patrons. Per the California State Library definition, San Francisco Public Library defines active patrons as a) patrons with unexpired library cards and b) patrons who had circulation activity within the last three years.

A. SUMMARY
This dataset contains the current San Francisco Board of Supervisor district boundaries approved by the San Francisco Redistricting Task Force. This dataset was created in April 2022 following redistricting based on the 2020 Decennial Census.

B. HOW THE DATASET IS CREATED
This dataset will be updated to reflect the most current Supervisor District boundaries available. It currently reflects the same boundaries found in Supervisor Districts (2022). More information on how this was created can be found in the datasets by year: Supervisor Districts (2022) and Supervisor Districts (2012)

C. UPDATE PROCESS
Supervisor District boundaries are updated every 10 years following the federal Decennial Census. The Supervisor District boundaries reflected in this dataset will be manually updated after the next Decennial Census in 2030.

The dataset is also manually updated as new members of the Board of Supervisors are elected or appointed. The most recent manual update date is reflected in the 'data_as_of' field.

D. HOW TO USE THIS DATASET
This dataset can be joined to other datasets for analysis and reporting at the Supervisor District level.

If you are building an automated reporting pipeline using Socrata APIs, use this dataset for reporting that will automatically update after each census to reflect the most recent Supervisor District boundaries. If you'd like your boundaries to remain static, see the Supervisor Districts (2022) dataset.

***As of November 2023, this map has been updated to use a new format. For details, please see here.*** The City imposes development impact fees on development projects in order to mitigate the impacts caused by new development on public services, infrastructure and facilities. For example, the burden on the transit system created by a new office building is offset through the payment of an impact fee used to improve MUNI.

Impact Fees are different from, and apply in addition to, application fees, which are used to cover the cost of the City’s review of a given proposal. For the most part, impact fees are assessed by the Planning Department and are collected by the Department of Building Inspection (DBI) upon permit issuance.

Some impact fees apply throughout the City to various types of development projects. Others apply only in certain neighborhoods. Another type of impact fee only applies when a builder chooses to pay them in-lieu of meeting a particular Planning Code requirement (e.g. usable open space).

***As of November 2023, this map has been updated to use a new format. For details, please see here.*** The Department of Public Health and the Mayor’s Office of Housing and Community Development, with support from the Planning Department, created 41 neighborhoods by grouping 2010 Census tracts, using common real estate and residents’ definitions for the purpose of providing consistency in the analysis and reporting of socio-economic, demographic, and environmental data, and data on City-funded programs and services. They are not codified in Planning Code nor Administrative Code.
This dataset is produced by assigning Census tracts to neighborhoods based on existing neighborhood definitions used by Planning and MOHCD. A qualitative assessment is made to identify the appropriate neighborhood for a given tract based on an understanding of population distribution and significant landmarks. Once all tracts have been assigned a neighborhood, the tracts are combined to produce Analysis Neighborhoods which is available at https://data.sfgov.org/d/p5b7-5n3h

These are complaints from Housing, Building, Electrical, Plumbing, and Code Enforcement divisions within the Department of Building Inspection. Routine and non-routine inspections from the housing division are tracked using complaints only if violations are found during the inspections. The NOVTYPE field can be used to determine the source of the complaint.

The San Francisco Controller's Office maintains a database of payments made to vendors from fiscal year 2007 forward. This data is presented on the Vendor Payments report hosted at http://openbook.sfgov.org, and is also available in this dataset in CSV format, which represents summary data by purchase order. We have removed sensitive information from this data – this is intended to show payments made to entities providing goods and services to the City and County and to protect individuals. For example, we have removed payments to employees (reimbursements, garnishments) and jury members, revenue refunds, payments for judgments and claims, witnesses, relocation and rehousing, and a variety of human services payments. New data is added on a weekly basis.

Supplier payments represent payments to City contractors and vendors that provide goods and/or services to the City. Certain other non-supplier payee payments, which are made to parties other than traditional City contractors and vendors, are also included in this dataset, These include payments made for tax and fee refunds, rebates, settlements, etc.

Inventory of tall buildings in San Francisco, focusing on attributes that are relevant to building performance during an earthquake or to post-earthquake recovery. Where possible, the attributes were collected from permitting documents at the Department of Building Inspections. As of October 1, 2018, this database includes a complete list of the 156 buildings taller than 240 ft, as well as another 24 buildings over 160 ft. For more information on the Tall Building Safety Strategy, see http://OneSanFrancisco.org/Resilient-SF.

Consolidated Infant, Pre-K, and K-14 education points for facilities both public and private.

Point features are intended to be located within a building footprint relevant to each site, so that they can be used to select an appropriate building footprint or parcel as seed for any required buffering.

Buffering may be applied when limiting possible sites for certain businesses or specific individuals, whenever these must remain a minimum distance from school locations.

Data current as of December 8, 2015

The purpose of the San Francisco Communitywide Greenhouse Gas Inventory is to measure and track greenhouse gas emissions to determine progress towards meeting the City's climate action goals. The Department of the Environment collects this data from various sources and calculates the emissions per current greenhouse gas protocols. This data supports San Francisco's climate change planning and mitigation strategies.

Note: Greenhouse gas emissions were calculated based on the ICLEI 2012 U.S. Community Protocol Version 1.0. San Francisco inventories are completed in accordance with the ICLEI U.S. Community Protocol (USCP) for Accounting and Reporting of Greenhouse Gas Emissions. The methodology and sectors tracked were third party verified in inventory year 2012. The subsequent inventories are completed according to the guidance of the verifiers. The third-party verification memo for 2010 is available at http://sfenvironment.org/download/2010-community-greenhouse-gas-inventory-3rd-party-verification-memo-march-2013 and for 2012 at http://sfenvironment.org/download/2012-community-greenhouse-gas-inventory-3rd-party-verification-memo-january-2015. In 2015, the City began reporting its emissions to C40 to improve its GHG emissions inventory by using a newer protocol to estimate emissions referred to as the Global Protocol for Community-Scale Greenhouse Gas Emissions Inventories (GPC). GPC is a framework unifying emissions inventories globally while incorporating new categories to track. San Francisco has been tracking its emissions since 1990; hence, it continues to use the ICLEI USCP. Today, San Francisco continues to disclose emissions under the GPC framework for reporting purposes to and compliance with the Global Covenant of Mayors (GCOM).
