Removing a street that is government property

Hello! I was wondering if it is possible to remove about 50% of a street that is part of the Jet Propulsion Laboratory (JOL/NASA)? It is located on Oak Grove Drive in La Cañada , CA? Thank you!

If there is no access or it is limited you can do this yourself on Open Street map which is where the source data comes from. Your map / progress will then be updated at some point when the city is synced with OSM.
