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