                  of factors that can be considered: The large majority of 
                  jurisdictions include social, health, risk, and, to a lesser 
                  degree, economic factors as part of assessment. Other factors 
                  that are taken into account include cultural-historical heritage, 
                  archaeology, visual impact, material assets, land use by indigenous 
                  peoples, community structure, and landscape (see Box 4.5).
