Sullenberger, who lives in this San Francisco Bay Area suburb, has been lauded nationwide for gliding Flight 1549 to an emergency river landing on Jan. 15 after both of the plane's engines were disabled following a collision with a flock of birds. All 155 passengers and crew members were rescued.
Community members planned to celebrate his feat with music, an honor guard and other presentations.
Sullenberger has said little publicly about his experience. Although he and wife Lorraine planned to attend Saturday's ceremony, they were not expected to speak at length, a family spokeswoman said.
Sullenberger attended the inauguration of President Barack Obama on Tuesday, and the family returned to California this week.
Katie Couric has landed the first interview with Sullenberger and his crew. It is scheduled to be shown on CBS' "60 Minutes" on Feb. 8.
