These footprint extents are collapsed from an earlier 3D building model provided by Pictometry of 2010, and have been refined from a version of building masses publicly available on the open data portal for over two years.The building masses were manually split with reference to parcel lines, but using vertices from the building mass wherever possible.These split footprints correspond closely to individual structures even where there are common walls; the goal of the splitting process was to divide the building mass wherever there was likely to be a firewall.
An arbitrary identifier was assigned based on a descending sort of building area for 177,023 footprints. The centroid of each footprint was used to join a property identifier from a draft of the San Francisco Enterprise GIS Program's cartographic base, which provides continuous coverage with distinct right-of-way areas as well as selected nearby parcels from adjacent counties. See accompanying document SF_BldgFoot_2017-05_description.pdf for more on methodology and motivation

Privately-owned public open spaces (POPOS) are publicly accessible spaces in forms of plazas, terraces, atriums, small parks, and even snippets which are provided and maintained by private developers. In San Francisco, POPOS mostly appear in the Downtown office district area. Prior to 1985, developers provided POPOS under three general circumstances: voluntarily, in exchange for a density bonus, or as a condition of approval. The 1985 Downtown Plan created the first systemic requirements for developers to provide publicly accessible open space as a part of projects in C-3 Districts. The goal was to “provide in the downtown quality open space in sufficient quantity and variety to meet the needs of downtown workers, residents and visitors.” (See Planning Code Section 138 for regulations). Since then, project sponsors for residential projects may provide POPOS instead of their required open spaces in the Downtown Residential (DTR) and Eastern Neighborhoods (Section 135 of the Planning Code).

The Mandatory Soft Story Program provides a weekly update on the status of properties identified as soft story.

The dataset represents the different Compliance Tiers for the Mandatory Soft Story Program and the current status of these properties. For more information on the Compliance Tiers, please contact the Soft Story Program.

Tier I. Buildings that contain a Group A, E, R- 2.1, R-3.1 or R-4 occupancy on any story

Tier II. Buildings containing 15 or more dwelling units, except for buildings assigned to Tier I or Tier IV

Tier III. Building not falling within the definition of another tier.

Tier IV. Buildings that contain a Group B or M occupancy on the first story or in a basement or underfloor area that has any portion extending above grade, and buildings that are in mapped liquefaction zones, except for buildings assigned to Tier 1.

San Francisco International Airport (SFO) data on Landings Statistics. Airport data is seasonal in nature, therefore any comparative analyses should be done on a period-over-period basis (i.e. January 2010 vs. January 2009) as opposed to period-to-period (i.e. January 2010 vs. February 2010). It is also important to note that fact and attribute field relationships are not always 1-to-1. For example, Aircraft Landings belonging to United Airlines will appear in multiple attribute fields and are additive, which provides flexibility for the user to derive categorical Aircraft Landings Statistics as desired.
