This series specification describes the two classifications of Survey Technician III and Land Surveyor which, under direction at the lower level and under general direction at the higher level, performs routine and difficult land surveying duties in the field and office in both the Survey Support and County Surveyor Sections of the Survey Division of the Public Works Agency; and performs other related duties. The class of Land Surveyor is distinguished from the next lower one of Survey Technician III in that the former class is the first level of the professional Land Surveyor classifications exercising the independent control and direction of land surveying work and land surveying decisions which can only be made by a licensed Land Surveyor and are described in the following Examples of Duties. Certain positions in this class may be responsible for assigning, monitoring and reviewing the work of multiple survey parties within one of the Division's major specialized survey activities, such as Global Positioning System (GPS) Surveys, Boundary Determinations, and in the examination of record maps in the County Surveyor Section.
