Street and Address Data Maintenance Program


Cuyahoga County presently maintains a spatial (GIS) database of address points and 'intelligent' street centerlines for various purposes. This data set was originally compiled in 2006 and follows the State Of Ohio Location Based Response Systems (LBRS) Standard, detailed here: Ohio OGRIP

This set is currently being brought up to the date of the most recent aerial photography (March 2015), with quality checks and the addition of mostly residential housing developments initiated or continued since the initial compilation date.

It can and should be shared among public agencies interested in a standard set of validated, existing streets and addresses for Cuyahoga County.

Some important uses of this data are, but not limited to:

  • GIS Analysis and Mapping
  • Geocoding
  • LBRS (Emergency Services)
  • Linear Referencing - Road Engineering
  • Address Entry Form Design and a wide variety of other application development


Cuyahoga County GIS presently maintains this data using ArcGIS Desktop (version 10.3.1) in an Oracle Spatial RDBMS. The data can be converted to most standard GIS formats.

Cuyahoga County Addressing Notification System (CCANS) is an HTML5 Web Application developed using the Geocortex Framework to provide a collaborative notification effort. After enrollment in our participation program, this application should be used to alert the editing staff to the following conditions:

  • Errors in the existing data:
    • Data prior to 2006, despite our best efforts, may still be inaccurate.
    • Use the CCANS Standard Operating Procedures (SOP) document, provided upon enrollment in the participation program, to digitize notification features where errors exist straight on the CCANS map.
  • New addresses and centerlines:
    • Most missing development from the years 2006 - 2015 have been noted already and are actively being added. It is not necessary to notify the County about new development if it already appears in CCANS.
    • Most new developments take years to build after dedication. Some never get built! The County has a building permit database that is used to track these additions.
    • The "up-to-date standard" goal is to match the latest photography (currently March 2015). The County hopes to acquire new photography every two years.

Participation and Contact

If you would like to participate, please contact the GIS Department to begin the application process.
If you are already a participant, please access the application using the link that was provided after enrollment.

For more information on using the CCANS site, please view or download the CCANS Standard Operating Procedure PDF.


Data can be acquired through our GIS Data website.

  • Data can be provided in most standard GIS and some non-GIS formats upon request
  • Any static download must be understood to be static: any changes made to the data after download will not be replicated in the County's database (See upload information below)


  • Cuyahoga County hopes to serve as the central repository for Address and Centerline data throughout the County
  • If you have a set of address points or centerlines already in a GIS format for an area, the County may be able to accept them. However, this is not the preferred standard operating maintenance procedure and will be handled on a case-by-case basis.
    • There are digitizing rules and data design models to be followed, so in most cases, data provided to the County will serve merely as a template for re-digitizing
