Beneficial factors may include such items as desirable views, proximity to desirable public or cultural facilities, or proximity to dedicated open space or greenbelts. Detrimental factors may include such items as offensive odors, undesirable land uses, contamination, and noxious weeds. Farm properties can be especially impacted by environmental factors such as noxious weeds, frost, incidence of hail, floods and droughts, and variations in crop yields. Appraisers should list and describe those beneficial and detrimental factors that may impact the utility and value of the land.
