The community celebration at BJ's Restaurant and Brewhouse at 4585 Chino Hills Parkway recognized Norton-Perry for her the dedication and service.
Earlier this year, after two decades of being on the City Council, Norton-Perry announced that she was stepping down from her elected seat when her term expires later this year. She was first elected in 1991 when the city was incorporated.
"This was a small group of people who have come together to honor my service, which is very humbling," Norton-Perry said.
"And I'm embarrassed to be in a position to be recognized, to be truthful, I've done it out of my heart, and I don't believe I am anyone special. The last few days has been very difficult ... I was very proud to serve."
Norton-Perry, who was a member of the city's incorporation committee, was the first female and youngest mayor in San Bernardino County when she was elected in 1991. She has served on the council since.
Norton-Perry has also represented the city and the region on numerous committees specializing in transportation, air quality, land-use planning and public policy.
Council members will honor Norton-Perry at its 7 p.m. Tuesday meeting at City Hall, 14020 City Center Drive.
Norton-Perry's last day on the council has not been finalized.
