Business Improvement Districts - mattyschell/nyc-spatial-rolodex GitHub Wiki

The Department of Information Technology and Telecommunications maintains Business Improvement Districts in the Citywide Street Centerline database. The Department of Small Business Services provides Citywide Street Centerline editors with info on Business Improvement District boundaries by indicating a list of tax lots or by sending shapefiles.

Citywide Street Centerline editors create a single Business Improvement District by snapping polygons to street centerlines and shore lines. Snapping to the centerline is important for geocoding, which in some functions interpolates geocoded points as slightly offset from the centerline. Polygons defined by tax lots or on the sidewalk side of the curb line may not geocode in these cases.

Some Business Improvement Districts are multi-part polygons and may be geometrically invalid depending on the software you are using. The standalone Citywide Street Centerline ESRI Geodatabase feature class is named "businessimprovementdistrict."
