Procedure for the Change of Public or Private Street Names in Unincorporated St. Louis County, Missouri Prepared by the St. Louis County Department of Transportation & Public Works 1)
Follow these step-by-step instructions if you wish to change a public or private street name or road name in unincorporated St. Louis County, or a St. Louis County maintained major road on the St. Louis County Arterial Road System ("ARS") in both incorporated (City or municipality) or unincorporated St. Louis County, go to step #3. For streets or roads in a City (municipality), not an ARS road, go to step #2. A current listing of ARS roads can be found at: https://stlouiscountymo.gov/st-louis-county-departments/transportation-and-publicworks/roadway-publications-and-manuals/. This procedure is not for unnamed roads needing to be officially named. For more information on the naming of an unnamed road, contact the St. Louis County Assessor's Office (at the phone number listed on Page 3 of 4).
2)
Street and road name changes within a City (municipality) (other than an ARS road), shall take place through that City (municipality), not through St. Louis County. The Assessor's Office and the appropriate City (municipality) should be contacted prior to the changing of a street or road name within that City (municipality), to check for duplication of street names and focus on any addressing problems that would occur as a result of the street name change.
3)
The Department and Assessor's Office should be contacted prior to the preparation of the street name change petition in unincorporated St. Louis County and for roads maintained by St. Louis County in a City or municipality (ARS roads). They will try to help you with this procedure. Contact information can be found on Page 3 of 4 of this document.
4)
For unincorporated streets or roads (or ARS roads), a "Petition for Change of Street Name" is to be prepared by a Petitioner, on forms approved by the Director of the St. Louis County Department of Transportation & Public Works ("Department"). The Petitioner is typically someone who lives on or owns property on the street or road proposed for a street name change. A blank PDF Petition, a fillable PDF Petition, and a copy of the "Street Name Change" procedure wording contained in Chapter 1105.125 - Procedure for Change of Street Name (Chapter 1105, Title XI SLCRO 1974 as Amended) (most recently amended by St. Louis County Ordinance No. 26,072, 2015), are attached to this procedure list, and is also available on the Department's "Roadway Publications & Manuals" Internet webpage at: https://stlouiscountymo.gov/st-louis-countydepartments/transportation-and-public-works/roadway-publications-and-manuals/ . A listing of ARS roads is also shown on this webpage.
5)
The petitioner should list on the "Petition for Change of Street Name", the printed names and addresses of all the current property owners abutting and affected by the proposed street name change. The street location and property information can be found in the "Property Lookup" app, located on the "Interactive Maps for St. Louis County" GIS webpage at: https://datastlcogis.opendata.arcgis.com/app/e70f8f1814a34cd7bf8f6766bd950c68 . The current property owner's information should be shown on the map when using a left mouse click inside the property lines. This list of current property owners would include all the abutting owners of record for occupied buildings, vacant buildings, rental property, vacant lots, common ground, etc. All abutting and/or affected property owners, as previously described, shall be notified of the proposed street name change request by the petitioner. Proof of proper notice shall be by signature on the petition,
