San Antonio Heights, California

San Antonio Dam is an embankment flood control and debris dam on San Antonio Creek in San Bernardino County, California, about 5 miles (8.0 km) north of Ontario. The dam was authorized by the Flood Control Acts of 1936 and 1938 as part of a major program to provide flood protection in the Santa Ana River system. Construction began in April 1952 and finished in May 1956. The dam controls runoff from a rugged catchment area of 27 square miles (70 km2) in the San Gabriel Mountains.The dam was built by the Los Angeles District of the U.S. Army Corps of Engineers. The dam is 3,850 feet (1,170 m) long, 160 feet (49 m) high above the foundation, and 130 feet (40 m) above the riverbed. The main embankment contains 6,050,000 cubic yards (4,630,000 m3) of material. The reservoir behind the dam is usually dry, but can fill with up to 11,880 acre-feet (14,650,000 m3) of water after large flooding events. A concrete overflow spillway on the west side prevents overtopping and drains to the San Antonio and Chino Creek channels, which were lined with concrete between 1956 and 1960 to protect against such an event.A project has been underway since 2012 to remediate seepage problems at the toe of the dam during heavy rainstorms. The dam is considered a high hazard structure.

Maloof also replaced many of the house's functional elements with his own creations, including door handles and surrounds, rafters, and even toilet seats. Maloof used the adjacent workshop and display room to build and show his furniture, and he experienced his greatest period of success in the 1960s and 1970s while working in the house. The house was relocated in the early 2000s when California State Route 210 was built through the area; it is now a museum of Arts and Crafts work.The property was added to the National Register of Historic Places on November 9, 2010.

Created by sculptor August Leimbach and funded by contributions, the Madonna of the Trail monuments were intended to provide a symbol of the courage and faith of the women whose strength and love aided so greatly in conquering the wilderness and establishing permanent homes. Dedicated in 1928 and 1929, the twelve statues became sources of local pride. Through the continuing efforts of local and national groups, all are currently in good condition and on display.

The Casa de Rancho Cucamonga, commonly known as the John Rains House, is a historic house located at 8810 Hemlock St. in Rancho Cucamonga, California. The house was built in 1860–1861 after John Rains purchased the Rancho Cucamonga land grant in 1858 from the Tapia estate. The brick house featured its own cooling system, which used ducts to send creek water under the house. John Rains was a prominent businessman and socialite who opened California's first commercial winery, and his house hosted lavish parties for other local elites. Rains' fortunes soon took a turn for the worse, though; he had to mortgage the house after several business failings, and in 1862 he was murdered. Maria Merced Williams, Rains' wife, who had originally inherited the property from her father, attempted to regain ownership after Rains' death but the rancho was gradually parceled out until she lost the entire property in the 1870s due in part to Rains arranging through his personal attorney to have only his name listed on the deed to all the properties. Through this lawyer the properties were signed over to his brother-in-law who gained his property from marrying Merced William's sister who had received it as the other half of the inheritance.The house was added to the National Register of Historic Places on April 24, 1973. It is currently open to the public as a historic house museum and is a branch site of the San Bernardino County Museum.
