Homeowners receiving Arizona’s Historic Property Tax Reclassification in Pima County

GIS By February 20, 2017 Tags: , , , , 4 Comments

For its recipients, Arizona’s Historic Property Tax Reclassification is a pretty great deal. Homeowners who qualify get their assessment ratios slashed from 10% to 5%, cutting their property tax bills in half. This map shows the residential properties in Pima County that receive this benefit. If you zoom in and click on an individual parcel, the map should display that property’s street address and parcel number. For a re-sizable window in a separate tab, click here.

How Gary Johnson and Jill Stein fared in Pima County’s voting precincts

GIS By February 8, 2017 Tags: , , , , No Comments

Libertarian presidential candidate Gary Johnson received 15,620 votes in Pima County, 3.66 percent of the total 427,102 ballots counted. Green Party presidential candidate Jill Stein received 6,200 votes, or 1.45 percent of the total. The color gradient on the maps below represents the range of vote percentages for each candidate. The darkest areas are the precincts where each did best. Johnson’s strongest showing was in Precinct 114 (Davis-Monthan Air Force Base), where he received 42 votes out of 412 cast, or 10.19 percent of the vote. Stein’s strongest was in Precinct 44 (West University and downtown), where she received 50 votes out of 1,433 ballots cast, or 4.4 percent of the vote. As with the previous presidential map, you can zoom in to see areas in greater detail. If you click somewhere on the map, statistics for that precinct (including percentages and vote totals for all presidential candidates) should display above your cursor.

This map shows each of Pima County’s 248 voting precincts with a shades of blue and red to indicate the respective degrees to which they favored the Democratic or Republican candidate, Hillary Clinton or Donald Trump. You can zoom in for a closer look, and click on any precinct for more detailed information. For a resizable version in a separate window, click here.

Although they were on the ballot, I chose to ignore vote totals for the Libertarian and Green party candidates for the purpose of this map. I also ignored write-in votes, over-voted, and under-voted ballots. None occurred in percentages that exceeded single digits, with the exception of Gary Johnson, who received 42 out of 412 votes—10.19% of the total—in precinct 114.

This map shows Arizona’s 353 golf courses. (For a resizable version in a separate window, click here.) If you click on one of them, the map should display the course’s name, number of holes, whether it is public or private, and in some cases, what type of water source it uses. (The source file only contained this data for a limited number of courses.)

The GIS data shown here is provided by the Central Arizona Project, and was obtained via the AZGEO Clearinghouse, an great resource for GIS professionals and enthusiasts.
