This appendix presents some of the basic data used in developing this plan. These data were taken from individual building permit records examined at the Santa Cruz County Building Department. The local household size used in the planning process was calculated from 1990 Census data for Block Group 99601, which includes most of the planning area. Total household size as calculated by dividing the population by all housing units was used because the current population estimate, water consumption, and other planning calculations based on household size should be based on housing unit counts, not counts of occupied homes. This chart is based on 1990 Census age data.
Acreages are approximate.
Note that the acreage of private land given in this table does not match that given in Table B-6 because the private land use data in that table come from a different source, covering a slightly smaller area. This table is based on tax assessment data for Elgin Elementary School District 2500, as provided by the Santa Cruz County Assessor's office and the Arizona Department of Revenue. The number of homes permitted on ranch lands was obtained by deducting lands that are not available for development, primarily the private lands of the Appleton-Whittell Research Ranch, from the total of ranch lands, deducting 180,000 square feet for each existing ranch home, then dividing the remaining ranch land by 180,000 square feet. These data come from the Arizona Department of Transportation's Traffic on the Arizona State Highway System.
