Narrative:

While coming in to land, we were unable to attain trailing edge flap extension beyond 1 degree. The checklist led us to the alternate flap extension procedure, which proved unsuccessful (in fact, when toggling the alternate extension switch down, the trailing edge flaps went up in the opposite direction). Dispatch and maintenance control were consulted. All safe and logical options were explored, and the decision was made to land on runway 19L with the leading edge devices out and only 1 degree of trailing edge flaps extended. As a precaution, an emergency was declared. The subsequent approach and landing were uneventful. The passenger were briefed by myself twice, and the message expressed that this was not a dangerous situation. The flight attendants were both prebriefed, and postbriefed with no subsequent concerns. While deplaning, everyone expressed gratefulness. There were no negative comments or concerns expressed by the passenger. Maintenance was briefed face-to-face along with a logbook write-up. They mentioned to me that this was a previous write-up.
