New street names and addresses take effect Jan. 16, 2018

The final phase of a years-long process to change street names and addresses on Aberdeen Proving Ground will become effective Jan. 16, 2018.

On this date, covers will be removed from countless street signs, revealing new street names across the range and cantonment areas of APG North (Aberdeen) and APG South (Edgewood). The most recent changes will apply to all organizations assigned to APG receiving official mail.

Earlier in 2017, housing and recreation lodging areas converted to the new street names and addresses. The Directorate of Public Works continues to work with local and commercial partners to help expedite address databases updates.

“The address and street name changes on APG may seem like an unnecessary hassle, but it makes us safer in the long run,” said APG Garrison Commander Col. Rob Phillips. “Emergency services will now be able to get to locations on-post faster,” he said adding, the installation-wide effort will bring APG up-to-regulation with a standardized addressing system.

“We learned some tough lessons during the transition of residential addresses,” Phillips said.

“The Garrison is working diligently to bring us back on course as we move into the final phase of the change-over. Our subject matter experts are working to educate on- and off-post communities to ensure both mail and visitors can find their intended destinations on APG.”

Public safety

Charles Eckert, chief of the DPW Engineering Division, said public safety is the root cause of the changes.

“APG is converting to a street addressing system as a public safety initiative tied to APG’s enhanced 911 system, which will be compatible with the 911 Emergency Response System used in the surrounding counties,” he said.

“This involves renaming streets whose names are duplicates of those in the surrounding counties and revising the building addresses to comply with the United States Postal Service address numbering convention. This will eliminate confusion as to the location of emergencies and result in faster response times.”

He added that the updating of GPS systems is “an involved process.”

“[It] requires submission of the street and address revision to Harford County which then incorporates the changes into its roadway system database. The revised database is then pushed to the State of Maryland for incorporation into its database. GPS systems will download the state’s database to update their systems, based on each provider’s schedule,” Eckert said.

“Harford County has forwarded the revised database to the State of Maryland [and] it is anticipated that the new street names and addresses will take upwards of 180 days to be incorporated into third-party mapping services.”

Strip maps with the revised street names have been prepared and will be available at the visitor centers at the APG North (Aberdeen) and APG South (Edgewood) entry gates. Electronic copies of the strip maps have also been given to facility managers. It should be noted that while street names and numbers are changing, building numbers will remain the same.
