1.0 Introduction
The Level A economic analysis of potentially irrigab1e acreage
(PIA) on the Southern Ute and Ute Mountain Ute Indian Reservations
specifies crop budgets and gives estimates of on-farm returns for
potentially irrigab1e lands in ten different climatic zones. (The
Level A economic analysis is described in a separate report.) The
results of the Level A economic analysis were used by Boyle
Engineering to identify land parcels in the San Juan Watershed that,
based upon pre1iminary,investigations, had sufficient on-farm returns
to justify water delivery costs. This report describes a Level B
economic analysis of individual parcels in the San Juan Watershed
preliminarily classified as PIA by Boyle Engineering. The purpose of
this Level B economic analysis is to make any necessary adjustments in
the economic analysis to reflect the unique characteristics of
individual parcels.
The Level B economic analysis includes three factors that were
not considered in the Level A analysis. First, land classes (soil
types) that may affect crop suitability are considered and changes in
cropping patterns are made when indicated. Second, the Level B
economic analysis incorporates land preparation charges for tree,
brush and grass removal that will be necessary prior to irrigated
agricultural use. Finally, the Level B economic analysis considers
economies of scale and farm efficiency factors as they apply to
individual parcels or groups of parcels and makes any adjustments in
cost and/or returns necessary for a final PIA determination. The
methods used in making these adjustments are described below.
