The database here is not clear at all on this. I don't have my computer in front of me, so I'm not 100% positive about their SILVER-1, but it should go like this:
SILVER-1 - 40384
SILVER-2 - 41600
SILVER-3 - 41632
SILVER-TA - 867.7625 N247
OC Harbors, Beaches and Parks split off from R&DMD and R&DMD is now reoganized as OC Public Works.
