Our History

Diamond Bar Country Estates emerged from the earliest developments meticulously orchestrated by the Transamerica Corporation in the 1950s. Establishing its association in 1966, initially under the name “Equestrian Estates,” the community swiftly transitioned to its lasting identity as “The Country Estates,” which persists to this day. During the 1980s, The Country stood as Southern California's largest equestrian community, boasting 720 horse lots. However, as urbanization and demographic shifts occurred, horse owners gradually relocated from the area. Consequently, fewer equestrian enthusiasts moved into the community over time. Formally established in 1989, the City of Diamond Bar attained incorporation 23 years following the inception of our distinguished Country Estates Association. The city derives its name from a local cattle brand rooted in the region’s Rancho heritage. Reflecting a cherished reverence for rural tranquility, “the Country living” is often regarded as the city’s unofficial motto, echoing the enduring spirit embodied by “The Country Estates.” During the 2000s, the integration of neighboring non-horse communities, including Crystal Ridge and Windmill, remolded the landscape of The Country Estates. Consequently, distinct architectural variations emerged, reflecting the diverse origins of these integrated neighborhoods, and contributing to the unique character of our community. The community’s response to these changes was transformative. The once bustling indoor horse show arena, once a centerpiece of equestrian activity, underwent a remarkable conversion. It was repurposed into an indoor community center, complete with sports courts, adapting to meet the evolving needs and interests of its residents. The evolution of our infrastructure has reshaped our community, transitioning it from a suburban rural enclave to a cosmopolitan hub with convenient access to amenities. Formerly rustic, uneven roads have been modernized into sleek urban streets, featuring stylish concrete swales flanking their edges. The trail easements originally intended for horse riding, once integral to our landscape, have regrettably ceased to receive maintenance from the association. However, the abiding presence of the two-rail country-style fence serves as a symbolic reminder of our community’s heritage.
