§ 40-61. Surveying and monumentation standards.  


Latest version.
  • (a)

    Adoption of Texas Coordinate System. Pursuant to V.T.C.A., Natural Resources Code § 1.071 et seq., the city hereby adopts a standard system of coordinates and elevations based upon the National Oceanic and Atmospheric Administration (formerly known as United States Coast and Geodetic Survey) data known as the Texas Coordinate System. Such standard system includes monumented control points, called survey markers in this chapter, large scale aerial photographs and city maps of engineering quality.

    (b)

    Approval of plats. The developer shall base all plats required by this chapter upon a survey upon the ground which must be tied to any survey marker which is located within 2,000 feet of the nearest boundary line or corner of the tract of land shown on such plat; provided, however, that if such tract of land shown on such plat is located farther than 2,000 feet from the nearest survey marker, but such tract is a part of a larger parcel of land in the same ownership, the nearest boundary line or corner of which is located within 2,000 feet of a survey marker, and which larger parcel is being developed and/or subdivided in sections, then the city shall require that the survey, upon which the tendered plat is based, is tied to the nearest survey marker.

    (c)
