Narrative:

On downwind for runway 28. Looked like they were setting us for a visual; and approach slowed us to 180 knots abeam the field heading east. As we slowed and configured; saw EICAS message te flap disagree. Flap handle at 20; flaps looked like they froze at 15 to 16 degrees. Asked approach for delay; they kept us at 6;000 feet in a box pattern. Ran the checklist; recomputed approach speeds; and declared an emergency. Captain did a great job communicating with the passengers; the flight attendants and approach control while I ran the checklist. Asked for airfield rescue and fire fighters' response as a precaution; uneventful landing and rollout. Taxied to the gate; leaving flaps in position so maintenance could check out what caused the problem.kudos to approach. When we asked for a delay before continuing the approach; their response was impressive: no drama; straight forward box pattern; approach as soon as we were ready. A pat on the back for our training; as well. Having practiced this type of problem in the simulator made our handling of it seem like we were just practicing for another checkride at the training academy.
