Narrative:

I was acting as first officer and PF of flight. Approaching dulles we received a flaps fail message on the EICAS. After completing the QRH, we notified dispatch and maintenance control of the problem and elected to declare an emergency while continuing for [a no flap] landing at dulles. We completed the descent and approach checklist, notified the flight attendant of the situation and made an announcement to the passenger of the abnormality and that we would experience a 'normal approach and landing with fire trucks approaching the aircraft after the completion of the landing.' my captain then assumed the controls and we executed a visual approach to runway 19L to a normal [no flap] landing. The captain brought the aircraft to a stop clear of the runway on taxiway K6 and had the operations vehicle and fire chief inspect the aircraft. With their clearance we taxied to the gate and shut down uneventfully.
