A temporary surveyor's mark refers to the style of marker rather than any permanence. This temporary marker has been in place for weeks. Surveyors were encountered during a walk in the park under high power lines. Conversation ensued as follows. "Is something new being built?" "No. We are surveying the existing high-power line towers." "SoCal Edison does not know where the towers are?" "Apparently not. We were hired and are doing the work." "Is the marker permanent?" "No temporary. We use a four-inch spike instead of an eight-inch spike." Temporary surveyor's mark is equivalent in concept to temporary buildings, both referring to the type of construction rather than any permanence. Temporary buildings at my high school are still standing 50 years later. (con0033a)
