You are aware that when an agency narrowbands their radios they nearly never change frequencies, they just start using a mode that transmits using a narrower signal width. A user that used a wide band frequency of 155.500 using a bandwidth of up to 25 kHz would remain on 155.500 but only use a bandwidth of up to 12 kHz after narrowbanding. That would free up two narrow band channels on either side of it for future users.
Think of it this way. When you trade out your car to a motorcycle, do you have to stop using the roads designed for a car and move to one designed for a bike? No, you simply ride on the same road, but take less space on the lane. When you ride with a buddy, you can ride side by side on that lane so two vehicles now take up the space originally designed for one.
