Name: Right of Way Street and Alley Openings

Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description:

Open in: [Superset)] [ArcGIS] or [Request format]

This dataset displays the City of Detroit’s public rights-of-way that have been dedicated to the City of Detroit. This includes the widening and expansions of streets, alleys, sidewalks, and berms. This layer also includes Joe Louis Greenways that have been processed as dedications. All proposed dedications must follow City Engineering’s standards.

This data is intended as a reference material of street and alley openings, but not designed for survey, accurate positioning, or legal documents. It is created as polygon feature class, dedicated information based on field measurements, types of Right of Way, and citations of Journal of the Common Council (J.C.C.) and legal description are included. The paper maps of the Street and Alley Openings, the raster layer version of those maps (Linen Map Markup Mosaic), and the Detroit parcel layer are used as base maps to create this data. The street and alley openings were recorded from 1831 till now throughout the whole city, and it will be updated on a monthly basis.
