Boundaries

For matching and analyzing demographic data collected and compiled by the U.S. Census Bureau & American Community Survey(ACS) to the geography of Census Block Group boundaries within the City of Philadelphia. These boundaries can change every ten years when the decennial census is conducted.

The basic unit of aggregation published by the US Census Bureau. Population statistics published for redistricting are distributed at the block level. In an urban area, this corresponds to approximately one city block. This block map has been altered to improve accuracy and align with the City of Philadelphia’s street centerline.

Update frequency of dataset: Weekly

Last Update Date: August 2023

Accuracy of attribute: Attributes are correct as per County of Chester Assessment Department

Positional accuracy of dataset:

The PARCELS layer (and derived copies PARCEL_PUBLISH and PRCL_POLY) was originally created through a conversion process of digitizing hand drawn tax maps into digital form and orientating the tax map sheets and parcels to the features depicted in the 1993 orthophotos. These parcel polygon features were adjusted based on aerial photography dated April 7, 1993, and road centerlines, right-of-way lines and other physical features generated from the same photography. While the imagery has a pixel resolution of 1.5 square feet, a positional accuracy of +/- 5 feet and is designed for use at a scale of 1 inch = 200 feet, the resulting PARCELS horizontal accuracy varies from reasonably accurate in the best cases to less accurate in the worst cases. Subsequent and current map update processes include metes and bounds entry from subdivision and deed information, as well as property corner locations based on GPS points and the utilization of our newest imagery datasets. While the update processes include more accurate methods, the resultant overall accuracy is still dependent on the surrounding parcel fabric's varied accuracy. Planimetric coordinates are based on the Pennsylvania State Plane Coordinate System South Zone and North American Datum 1983

Note: There is a difference between land use code and zoning. Land management occurs via a land use designation which determines the land use code. This designation specifies how land and resources within it is managed. Zoning designations define how a property can be developed and used and it is controlled by each township/borough. See below for list of codes.

City Council Districts for a variety of different years.

This layer was developed to aid the Surveys Division in planning, modifying and referencing the streets within a city plan of the City of Philadelphia. Examples include: building new streets, modifying existing streets, or observing current streets.

Data includes commercial and industrial zones, i.e. areas with specific federal-granted special amenities (tax incentives, loans/grants) meant to attract and support businesses in blighted areas. Blighted areas are defined as meeting one of seven city mandated criteria, including unsafe, unsanitary and inadequate conditions; economically or socially undesirable land use; and faulty street and lot layout.

This is the H3 (https://h3geo.org/) hex grid covering Philadelphia. H3 indexes points and shapes into a hexagonal grid. It is meant to be used as a standardized grid for aggregating data at different resolutions. Grids exist for resolution levels 7 to 10. Any cells that overlap the city limits were included.

Please note that the dataset below is a snapshot of data captured at one time and does not receive regular updates.

The Highway Districts dataset shows the boundaries of highway districts used for managing maintenance of roads.

This layer delineates the fifty-six sections of the Highway Division of the City of Philadelphia Streets Department. Sections can be aggregated into districts and subdivided into subsections. A Highway Engineer is responsible for each district. The section layer was developed to aid the Highway Division in the planning, organizing, and maintaining of the streets within each of the six districts. Examples of maintenance include: paving, snow removal, concrete maintenance, and the monitoring/repairing of ditches and potholes.

Election results are published at the Ward and Ward-Division levels. However, wards and ward divisions are adjusted on an ongoing bsais, and in order to map historic election results, it is necessary to have ward divisions that match the boundaries in effect at the time of the election. Historic ward and ward division boundary data are from PASDA, Azavea, and Robert Cheetham archives. In addition, some results from open records requests to teh City of Philadelphia. Data has been collected for 2003 to 2020. Attribute tables were modified to match across all years.

Districts with special sidewalk vending rules pursuant to Sections 9-204 (Sidewalk Vendors in Center City) and 9-206 (Sidewalk Vendors in Neighborhood Business Districts) of The Philadelphia Code.

This layer was developed to aid the Traffic Division in planning, organizing, and maintaining traffic flow within the City of Philadelphia. Examples include: the maintenance and placing of stop signs and signals and monitoring street travel direction.

The polygons in this dataset show the locations of vending regulations and relevant details like code references, links to the code reference, and regulation types (prohibitions, exceptions, or special vending districts). This dataset is updated on an as needed basis as governing legislation is passed.

The purpose of this dataset is to represent the Zip Code areas for the City of Philadelphia. The edges of Zip Codes are slightly modified for logical and cartographic purposes.

Polygon boundaries of Zoning Base Districts based on existing City zoning\ districts with revised codes applied per enactment of the new Zoning Code of December\ 2011, made effective August 22, 2012.
