Plumber in Rowland Heights, CA

The Mexican land grant Rancho La Puente was granted by Governor Juan B. Alvarado to John Rowland in April 1842, totaling about 18,000 acres (7,284 ha). Three years later, Governor Pio Pico amended the grant, enlarging it to nearly 49,000 acres (19,830 ha) and adding William Workman as a co-owner. In 1868, after they received their federal land patent the prior year, Rowland and Workman divided Rancho La Puente, with Workman largely taking the western and central portions and Rowland the northern, southern and eastern sections, including what became most of Rowland Heights. The east section of Rowland Heights, between Nogales Street and Brea Canyon Road, falls within Rancho Rincon de la Brea. The ranch of Rowland’s grandson, John A. Rowland III was behind the 99 Ranch Market near the corner of Gale Avenue and Nogales Street and the Rowland family owns part of that property today, leasing most of it for commercial use. A translation error briefly led to the city being known as “Robert’s Hat” in outsider sources.

Rowland Heights grew significantly during the 1990s. Originally built on a pig farm that covered much of modern-day Rowland Heights, the Rowland Homestead was mostly orange groves until the eastward sprawl from Los Angeles spawned working-class communities and affordable housing developments then formed. As the 60 freeway was extended beyond the western boundary, the community continued growth equal to that of most communities in Southern California. Development next to the freeway, zoned for industrial investment, eventually helped to support the housing developments that continue well into the 21st century.

Since the 1990s, there has been a significant demographic shift as many upper-class immigrants from Taiwan, China, and South Korea have settled in the hillside homes of Rowland Heights (and in neighboring regions such as Hacienda Heights, Walnut, and Diamond Bar). Also, Rowland Heights has also attracted immigrants from mainland China because the area is advertised in China as having high-end homes and convenient shopping centers. Many work at or own businesses in the nearby City of Industry. Additionally, Latinos have maintained a long-standing presence in the lower sections. The city has developed an eclectic suburban “Chinatown”, “Little Tokyo”, and “Koreatown”, mostly in the form of upscale strip malls. There are several large Asian product supermarkets – such as a 99 Ranch Market (billed as the chain’s largest location during the late 1980s), Hong Kong Supermarket, and New York City-based Great Wall Supermarket.
