The survey was <br />performed with Wild T-2 Theodolites and Electronic <br />Distance Measuring equipment. We have subsequently <br />tied this network to the California High Precision Geodetic <br />Network (HPGN) and has been readjusted to the North <br />American Datum of 1983 (NAD83) (1991.35 Epoch). <br />In 1988, Johnson -Frank & Associates, began providing subsidence monitoring services for the <br />City at the Turtle Rock housing development.
