Key Highlights
About Trilogy
Trilogy at Glen Ivy is a premier 55+ active adult community located in the Temescal Valley, California. Developed by Shea Homes between 2001 and 2008, the master-planned neighborhood consists of 1,317 single-family and attached homes nestled in the foothills of the Santa Ana Mountains. The community's design integrates the natural topography of Temescal Canyon with resort-style amenities. At its center is the Trilogy Golf Club, featuring a scenic 18-hole, par-72 championship course designed by renowned architect Ted Robinson Sr. The neighborhood's cultural and social life revolves around two major landmarks: the 13,000-square-foot Pacific Crest Lodge, which serves as a hub for continuing education and social clubs, and the 15,000-square-foot Blue Water Sports Club, dedicated to resident wellness and fitness.
The neighborhood features a deliberate design that balances dense suburban housing with expansive outdoor access. Residents benefit from a robust network of sidewalks that connect the entire community, making it highly walkable compared to the surrounding region. The aesthetic character is defined by large, well-maintained homes and consistent green parkways, which contribute to a pleasant visual environment. According to iHuus data, the area maintains high air quality despite the presence of nearby surface mining operations, which occasionally contribute to heavy truck traffic in the broader valley.
