Western Research Corporation <br /> <br />DATE: July 21. 1986 <br /> <br /> <br />RE: Clearin9 and Grubbing <br /> <br />1.0 Introduction <br /> <br />WRC's crop budgets include seed bed tillage operations specific to <br /> <br /> <br />each crop being grown. However, they do not include any canopy and brush <br /> <br />clearing costs required prior to preparation for crop production. Land <br /> <br />leveling costs are assumed to be negligible or incorporated into the costs <br /> <br />of developing the specific irrigation system to be used on the parcel and <br /> <br /> <br />are not included in the clearing costs or crop budgets. <br /> <br /> <br />This memorandum describes the land cover class assumptions, analytical <br /> <br /> <br />methodology, and clearing costs by land cover class. The clearing costs <br /> <br />are annualized assuming 8.375 percent interest over a 50 year project life. <br /> <br />2.0 Methodology <br />A. Classes of Land Cover <br />Three land cover classes are described by the amount of <br />juniper and pinion pine tree cover on the parcel: <br />. I - less than 10 percent tree cover <br />. II - 10 to 40 percent with an average of 25 percent tree cover <br />. III - more than 40 percent with an average of 70 percent tree <br />cover <br /> <br />jj ,~ <br />
