The Zoning Districts are a component of the Zoning Map which in turn is a key component of the San Francisco Planning Code. More information can be found here: https://sfplanning.org/zoning

This layer has 2 or more records for each intersection of the street centerline network. There is a record for each street name that intersects with a node.

Disclaimer: The Sea Level Rise (SLR) map shows the most extreme level of SLR possible. It is a very, very unlikely scenario that would only occur if no efforts to address SLR occur and both a King Tide and 100-year storm occur at the same time. The real purpose of the maps is to provide a broad net to help the City identify projects that that may be vulnerable. The data is based on what was in the ground as of 2010 and doesn’t include piers.

The inundation maps and the associated analyses are intended as planning level tools to illustrate the potential for inundation and coastal flooding under a variety of future sea level rise and storm surge scenarios. The maps depict possible future inundation that could occur if nothing is done to adapt or prepare for sea level rise over the next century. The maps do not represent the exact location or depth of flooding. The maps relied on a 1-m digital elevation model created from LiDAR data collected in 2010 and 2011. Although care was taken to capture all relevant topographic features and coastal structures that may impact coastal inundation, it is possible that structures narrower than the 1-m horizontal map scale may not be fully represented. The maps are based on model outputs and do not account for all of the complex and dynamic San Francisco Bay processes or future conditions such as erosion, subsidence, future construction or shoreline protection upgrades, or other changes to San Francisco Bay or the region that may occur in response to sea level rise. For more context about the maps and analyses, including a description of the data and methods used, please see the Climate Stressors and Impacts Report: Bayside Sea Level Rise Inundation Mapping Technical Memorandum, July 2014.

Coastal Zone Area The Coastal Zone Area is a component of the Zoning Map which in turn is a key component of the San Francisco Planning Code. The Zoning Map comprises: - Zoning Districts - Height and Bulk Districts - Special Use Districts - Preservation Districts - Coastal Zone Area - Special Sign Districts The official Zoning Map can be found in the San Francisco Planning Code: http://planningcode.sfplanning.org (click on the links under ZONING MAPS on the left navigation column).

Street Centerlines, active and retired.

This data layer is a mask covering the San Francisco mainland up to the county line, Treasure Island, and Yerba Buena Island.

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

These are the zoning districts and underlying parcels that are eligible to participate in San Francisco's Affordable Housing Bonus Program.
