Recorded by: Jeanette A. McKenna *Date March 4, 2014 X Continuation Update At this time, only¾ of the property is under trees (approximately 6.5 acres), with the remaining 3 acres left as open space for modern uses.
The Irrigation Pipe and Value System:
The irrigation pipe and value system identified within the property is quite typical of systems seen throughout Southern California. This particular type of system involves the establishment of one or more master valves that feed water into a buried concrete pipe system. These pipes have a series of "standpipe" distribution posts with individual flow channels. The system is gravity fed and, in the case of the orchard development , a row of pipe may be placed every 3 to 6 rows, depending on the size of the orchard. The establishment of a system of irrigation pipes and the master valve system is a considerable investment. The first recorded indication of such an investment in the property is recorded in 1921 and credited to D.B. Jack.
While the irrigation pipes are generally not marked, the master valve may have evidence of manufacturing. In this case, the master valve, identified along Victoria Avenue , was marked on the metal fixtures (gates, etc.). Here, the steel gate is marked "SNOW MFG. CO., LA CAL." The Snow Mfg. Co. of Los Angeles patented the "Gate Valve " in ca. 1933 (Serial No. 703,893), although its manufacturing and sales may easily have preceded 1933. The Snow Manufacturing Company of Los Angeles was operating as early as 1912.
Despite its early manufacturing and implementation on the property, this system is not unique to the area or indicative of any unusual or intricate design. It is a simple , gravity fed system used to water orchards via water pumped into the master valve system. In this case, it is possible the main source of water prior to 1914 was the Riverside Canal. However, once the canal was abandoned, alternative sources of water were required. It exact source of water for this property has not been determined , but given the master valve is along Victoria Avenue , the source is likely to be from Victoria Avenue or points north/northwest.
The Wind Machine:
The wind machine was located in the center of the property and consists of a single, tall and hollow metal pole with a single propeller style fan. No markings were found on this feature , as the base was too heavily overgrown to find any such markings.

Recorded by: Jeanette A. McKenna *Date March 4, 2014 X Continuation Update It is noted, however, that the Snow Manufacturing Co. also produced windmills and wind machines. Parsons (2010) notes that wind machines were often used to prevent frost damage to citrus. He states:
"Wind machines may regain popularity for citrus and blueberries. Wind machines are commonly used to protect crops in the western U.S. In calm conditions, an inversion of warmer air above the cold air at ground level can sometime develop .
Wind machines mix the upper warmer air with the colder lower air and raise the temperature in the crop zone by a few degrees. The volume of air moved and area covered are related to propeller design and horsepower. Newer types of wind machines have become available in recent years, and they range from 15 to more than 150 horsepower. While these wind machines are only effective in radiation frost conditions and raise temperatures only slightly, they can be useful in borderline frost conditions."
The design of the wind machine within the project area appears to be a later addition to the property, as it powered by electricity (not a gas driven system) and is made of galvanized steel.
Between 1941 and 1958, no improvements were noted for this property. In 1958, a $250 improvement is recorded.
McKenna et al. suggests this investment reflects the establishment of the wind machine by the owners of the L-Bar ranch. Assuming this feature dates to or before 1958, it is one of the historic (over 50 years of age) elements of the overall agricultural activities on the property.
McKenna et al. concluded the property, overall, is not a significant or important resource as defined in the various evaluation criteria. As a property failing to meet any of the criteria for recognition, McKenna et al. has also concluded there will be no adverse environmental impact if this property is redeveloped.
NOTE: None of the modern improvements are evident on the 1996 aerial photo. This photo shows the orange grove to cover the entire property.
