1.0 Introduction
This report describes the Level B economic analysis of arable
parcels in the San Juan West Watershed that were preliminarily
classified as practicably irrigable 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 Irrigable 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,
