They are all trunked. Newport News is P25, Type2 but right now only fire TAC 8 is using P2, All others still P1. Virgina Beach will soon be encrypting all LE. These are in the database and are accurate.
When I pass through, Ch. 16 is the best bet. Besides calling there to move to another channel, one get many warning from moving USN vessels. But if you are trying to hear from Petersburg, you may only hear USCG base stations as the ship's antennas are too low for your distance. The same is likely true for much of the commercial shore facilities. When I drive in, there is a great difference in the last 10 or 20 miles or so coming down I-64.I am the type that doesn't like to program an entire bandplan in for a select area, Does anyone have the frequencies and what their usage is for Norfolk/Virginia Beach/Newport News communications?
