This document discusses land use inventories and the LBCS (Land-Based Classification Standards) model. It explains that land use inventories help understand existing conditions, identify trends, and are important for comprehensive planning. The LBCS model provides a more detailed and flexible classification system than traditional models by using five dimensions: activity, function, structure, site, and ownership. The document gives examples of how LBCS has been used in different cities and provides two sample property codings to illustrate how LBCS can capture a variety of land uses. While more labor intensive than traditional models, LBCS provides benefits like revealing mixed-use areas and better tracking changes over time.
