  1. Boundary Surveys

  2. Lecture Outline • Cover Boundary Surveys as needed by civil engineers to locate a site ( property) • Sections covered: parts of 21-1 to 21-6 • Figures discussed: 21-1, 21-2 • Examples: all examples of property description within the sections discussed.

  3. Boundary Surveys • To define property boundaries, using plane surveying methods. • Usually deal with small areas. • Were applied as a early as 1400 BC, and still applied today. • Importance for engineers: to define the project boundaries when needed.

  4. Property Description • A property is described by one or a combination of the following methods: • Metes (to measure) and Bounds (boundary lines): • “Point of Beginning”, well referenced, given coordinates if possible. • Definite corners: given coordinates if possible • Lengths and directions of property lines • Names of adjoining property owners • Areas fig 21-1 • Read first description page 634

  5. Block-and-Lot • Adjoining parcels are subdivided into blocks and Lots. individual lots within the subdivided area are identified by block and lot number. • Map books in the record’s office give the location and dimensions of all lots and blocks. • Example: Lot 34of Tract 12314 as per map recorded in book 232 pages 23 and 24of maps, in the office of the county recorder of Los Angeles area.

  6. Description by Coordinates • Best method. • Coordinates of all the corner points are given in a state Plane Coordinate System. • Must mention the datum.
