1.0 Introduction
This report describes the Level B economic analysis of arable
parcels in the San Juan Watershed that were preliminarily classified
as practicably irrigab1e acreage (PIA) by Boyle Engineering. The
purpose of the Level B economic analysis was to make any necessary
adjustments in the Level A economic analysis to reflect the unique
characteristics of individual parcels. The Level A economic analysis
is described in a separate report entitled "Economic Analysis of
Potentially Irrigab1e Acreage on the Southern Ute and Ute Mountain Ute
Indian Reservations", Western Research Corporation, June, 1987. That
report presents the results of crop budget analyses for 10 different
climatic zones on the two reservations.
The Level B economic analysis includes three factors that were
not considered in the Level A crop budget analyses. First, land
classes (soil types) that may affect crop suitability were considered
and changes in cropping patterns were made where 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
incorporates economies of scale and farm efficiency factors as they
apply to on-farm costs and returns for individual parcels or groups of
parcels. The methods used in making these adjustments are described
below.
