All subdivision plats must be based upon a survey upon the ground using the official coordinate system. The official coordinate system is defined as “the standard system of coordinates and elevations based upon the National Oceanic and Atmospheric Administration data known as the
Texas State Plan Coordinate Grid System of 1983…”
All Ca, C2, C3F and STD plats must contain the following information:
