PURPOSE: This rule defines the various technical and legal terms used in this chapter. (1) Block: Block means a group of lots existing within well-defined and fixed boundaries, usually being surrounded by streets or physical barriers, and usually having an assigned number, name, letter, or other identifier through which it may be identified.

1. (2) Class of Property.

   1. (A) Rural property—Any property that is not urban or suburban that is used for the production of crops, livestock or minerals, or used as parks, forest or similar use.
   2. (B) Suburban property—Any property which is not urban property that is or is intended to be primarily used for residential purposes or property lying between residential areas whose value is influenced by the presence of such nearby developed real estate.
   3. (C) Urban property—Any property wholly or partly within the corporate limits of any city, town or village, and any commercial and industrial properties, condominium properties, town houses, apartments, and other multi-unit developments.
2. (3) Controlling corners. Controlling corners are the corners that determine the location of the record title boundary.
3. (4) Exterior corners of a parcel are the corners that define the shape and size of the parcel.
4. (5) Legal description. A description of real property by government survey, metes and bounds, or lot numbers of record. The description must be complete enough so a particular parcel of land can be located and identified.
5. (6) Linear error of closure is the square root of the sum of the squares of the error in north coordinates (Y) and in east coordinates (X).
6. (7) Material variations, whether between surveyed lines and lines of possession, or between record and measured distances or directions are variations so substantial and important that they would influence a reasonably prudent and otherwise knowledgeable person when making decisions in reliance upon the survey.
7. (8) Physical monument. The term physical monument refers to both natural and artificial physical objects which are accepted and used to mark boundaries and corners.

8. (9) Property boundary surveys.

   1. (A) A condominium survey is a survey executed to create and define condominium 10 CSR 30-2

property in accordance with Chapter 448, RSMo.

1. (B) An original survey is a survey which creates a new parcel out of a large parent tract, for the purpose of conveying the new parcel. Boundary adjustment plats, consolidation plats, riparian plats, lot splits, and minor subdivisions are examples of original surveys.
2. (C) A resurvey is a survey executed to remark, reestablish, restore or delineate the boundary line or corners of a parcel previously created by a deed, survey or subdivision.
3. (D) A subdivision survey is the partitioning of land into two or more parcels by platting the divisions of land in accordance with Chapter 445, RSMo and per the appropriate platting procedures, and from which parcels are then sold by reference to the plat of record.

1. (10) Radial survey measurement tolerance is the computed expected relative accuracy of any distance determined by radial surveying methods. It is computed using an analysis of component distance and direction errors.
2. (11) Radial survey method is the determination of the coordinate values of points by measuring directions and distance from a central point as opposed to determination of the coordinates of points by traverse. The determination of coordinates by “side shots” from a closed traverse is not considered a radial surveying method.
3. (12) Record title boundaries are the boundaries of the real estate described in the title of record.
4. (13) Relative position tolerance is the relative accuracy between all pairs of points in a survey. In practice it is computed for a sampling of pairs of points using either an analysis of component distance and direction errors or from a minimally constrained, correctly weighted least squares adjustment.
5. (14) Title of record. A title to real estate, evidenced and provable by one or more conveyances or other instruments all of which are duly entered on the public records.
6. (15) Traverse closure is the linear error of closure of the traverse computed either from an analysis of the component distance and direction errors or from the actual traverse measurements.
7. (16) United States Public Land Survey Corners. Corners of the United States Public Land Survey are those points that determine the boundaries of the various subdivisions represented on the official government plat such as the township corner, the section corner, the quarter-section corner, blank quartersection corners, center of section, fractionalsection corners, grant corner and meander corner.
